Dear Scott and Leonard:

Thank you for considering Saluki Engineering Company to design a solution to the lake water
temperature monitoring problem.

Attached is the proposal from the group identified as SP11-#62-SIPCLAKE. This proposal does
mimic some commercially available products but can be delivered to you at a greatly reduced
cost with the specific outputs required to connect into the monitoring system already in place.
This proposal was also written with the need of reliability and dependability in mind.

Thank you again for your consideration and we look forward to your response about our
proposal.




Sincerely,




Todd Peterson
Project Leader
SP11-#62-SIPCLAKE




                                                                                                  i
Executive Summary: TP


Due to the changing EPA requirements for water temperature at the edge of the mixing zone
and the lake water a way to monitor that temperature is now needed. This data needs to be
recorded at least every hour to maintain compliance with the EPA.

The Saluki Engineering Company group SP11-#62-SIPCLAKE proposed to build a buoy that will
transmit temperature, location and time data to a receiver that will be compatible with the DCS
control requirements. This project is designed to meet the EPA requirements for temperature
monitoring at the edge of the mixing zone.

This proposal shows how SP11-#61-SIPCLAKE plans to meet those requirements. They plan to
use a commercially available buoy with solar panels and batteries from the same supplier to
add to the reliability of the system and give them a stable platform to build from. They plan to
use temperature probes at three separate depths and a GPS receiver to pinpoint the location of
the buoy and give an extremely accurate time stamp.

All the signals will be processed and stored by an on board CPU and transmitted via RF signal to
a receiver at the plant approximately every 10 minutes. The receiver will also have a CPU that
will error check the data provide output ports compatible with DCS requirements.

The proposed cost of this project is $9750. This will include one buoy built and tested, with
spare components for the following systems; Temperature probe assembly, Buoy CPU with
GPS, Receiver CPU, one transceiver, and one solar panel assembly.

The proposed work will be completed by 22 December 2011

Introduction: TP

       Due to the ever changing laws and requirements of the Environmental Protection

Agency, EPA, a need to monitor the water temperature in the zone between the mixing zone of

a power plant outflow and the larger body of water used by the power plant during operation.

This problem is compounded by the fact that power plants are sensitive sites when it comes to

national security. This adds another layer of complexity in how data is handled inside the power

plant. Currently commercial systems available on the market would require modifications, or

additional components to be engineered to allow them to interface with the sensitive systems

of the power plant and already cost in the tens of thousands of dollars.


       A reliable, cost effective system to monitor the temperature at the edge of the mixing

zone is required to maintain compliance with the EPA requirements. This system must be a self

sustaining and maintenance free for a minimum of six months, preferably more. This system

must also report collected data at least once an hour to meet the EPA requirements. It also will

need to interface with the current systems at the power plant in such a manner as not to cause

any interference or open window for a malicious attack in some manner.


       It is understood that more features and sensors were requested for this project. With

the seriousness of the primary objective of this project of maintaining and the time restraints in

place the focus of this project will be exclusively the creation of a system to maintain

compliance with EPA regulations.




                                                                                                 1
Literature Survey: TP

        It is known commercial products are on the market already with some of the

functionality required as a solution to the monitoring and reporting problem. The literature

survey looks at the components required to construct a system of this type and the cost of

these systems. The survey is broken down in to sections or subsystems, which are as follows;

Platform or Buoy, Temperature probes, Long distance communication, GPS, Power

Requirements, Central Processing Unit or CPU.

Temperature Probes EB

         An accurate and reliable temperature sensor will be crucial to the functionality of the

entire system. There are many temperature sensors available on the market today. Sensors

from many different suppliers were looked at before making any decisions on which particular

sensor to use for the project. Table 2 shows some of the potential sensors that could be utilized

for this system.

GPS MR

         The device has to be within the mixing zone to satisfy the EPA requirements. Therefore

it must have a GPS feature. It will have to relay its position to the control room along with

temperature at set times. The GPS will also provide a time stamp so that the CPU can catalog

the data points. Table 4 shows three different GPS systems that could be used.

Power Requirements KD

         Provide power to multiple devices which have different voltage and power

requirements. The techniques used to achieve the required DC voltages are extremely common

and will involve utilizing standard design techniques and electrical components. Many common

systems require voltage regulation such as this system does. A simple example is a wall

transformer that converts an AC voltage into a pulsating DC voltage to power devices such as

phone chargers. Each of the desired voltages will be easily achieved using standard power




                                                                                                          6
supply components, such as, transformers, rectifiers, solid state voltage regulators, filter

capacitors, and other common passive components.


CPU TP

       To store and report the data desired requires the use of a device called a data logger.

There is almost an endless supply of different data loggers available on the market. Data

loggers can range in size, functionality, and cost. Due to the exacting nature of the project

designing a customizable data logger integrated with the other subsystems was researched.

The PIC microcontroller or Stamp-2B microcontroller are commercially available offer the ability

to manage the required inputs and outputs while maintaining minimum power consumption.




Project Overview: TP


       To meet the requirements put forth in the request for proposal and subsequent

communications the following design is being proposed. A buoy with solar panels & batteries,

GPS receiver, transmitter, and CPU on board will store and transmit data from the buoy to a

receiving station at the power plant. The Receiver will pass the data to a decoder/encoder

which will translate the signal into a usable format for the power plant. On the following page

Figure 1 is an overall system block diagram and subsystem assignments for our design.


       The design attempts to be modular for easy replacement of parts. The temperature

probes will be attached to a solid structure and removable in one unit. The GPS receiver chip

will be on the same PC board as the CPU which will make that whole unit replaceable. The solar

                                                                                                  7
panels and batteries while housed on the buoy are also replaceable as individual components.

Modular design will allow operators to make repairs in the event of system failure within an

hour. Failure to be repaired within one hour will result in loss of compliance with EPA permit.


       The encoder/decoder is specifically designed to interact with the power plant systems.

Translating the data communicated from the receiver, error checking it, and outputting it into a

signal usable by the control room.

Subsystems:


Buoy: TH
       The proposed buoy system is the NexSens MB-300 buoy. It is a self sustaining buoy that

has a buoyant force of 300 lbs and uses three solar power packs that produce 5W of power per

power pack. This Buoy system is specifically designed for river and lake water data logging. The

table below is taken from the MB-300/MB-400 user manual and it shows all of the buoy’s

specifications:


                                     Table 5 Buoy Specifications




                                                                                              10
         This buoy is rather light-weight (150 lbs), self sustaining, has a simple mooring system

and also has a six inch diameter cylinder to hold our electronics system. That cylinder is shown

below, in Figure 2, is a picture taken from the MB-300 manual. As one can see, the power

cables come up through the bottom and into the cylinder.




Figure 2 MB 300 with Solar Panels




         Another nice feature about this buoy system is the 6 inch diameter hole running down

through the middle of the buoy. This will allow us to run all of our sensors down into the water




                                                                                                    11
via this hole. Pictured in Figure 3 is a drawing from the MB-300

manual depicting the sensors the sensors could be deployed.


       Overall, the MB-300 is a great choice for the buoy system. It

has sufficient buoyant force, is self-sustaining, housing for

electronics, and is rather cheap. The total price for the buoy,

electronics housing, LED beacon, and mooring system is $4,700.

company has stated to offer upon purchasing.                                and Sensors



Temperature Probes: EB

       The temperature subsystem is important in that the temperature is the main area of

focus for the request for proposal. The temperature will be monitored at three different

depths in the lake, surface, 1ft, and 5ft respectively. The sensors will have a rigid structure to

keep them in place, which will also facilitate the running of the cables. The required operating

voltage of 2.5V will be supplied from the power subsystem. The sensors provide an analog

voltage output from 0V to 2.2V. The data outputted from the sensors will be interpreted and

stored in a CPU unit.


       The proposed sensors that will be used to do the temperature monitoring of the water

are the CS109L underwater temperature probes. The sensors are designed to be used

underwater. The CS109L gives accurate readings for the required temperature range and has

an analog voltage output. This output voltage will change linearly within the temperature range

of 0°C to 70°C. The manufacturer Campbell Scientific offers price discounts for educational use.

                                                                                                     12
Its price of $86 is relatively cheap when compared to some of the other high end sensors, while

still having a comparable accuracy and expected lifetime. Custom cable lengths are offered, and

support from the applications engineers is available if needed.


GPS: MR

        A GPS is a primary subsystem required for the project. It will provide latitude, longitude,

elevation, time, and date. The position is the primary reason for the GPS, as the buoy will have

to transmit where it is at in the lake. The time and date will be necessary for providing a time

stamp for the temperature and position data points. In the event that the buoy was to break

away this would also provide aid in locating it.


        There are two main parts of the GPS subsystem. The first is the antenna. The antenna

that will likely be used is the ANT-GPS-SH-SMA manufactured by Antenna Factor. It will be

mounted on the exterior of the buoy in a position to receive adequate reception. Power will be

drawn from the module by the cable that also relays the info from the antenna. The relevant

specifications are included in Table 6

        The second part of GPS subsystem is the module. The module that is proposed to be

used is the RXM-SG Module w/Ext Antenna (#28505) by Parallax Inc. The module will be

mounted directly on the CPU; therefore will draw its power from it. The antenna will be

connected to this module. The job of the module is to translate the data from the antenna and

send it to the CPU. The data can be found in Error! Reference source not found.Error!

        Once these parts are received, software will have to be written so that the data can be

interpreted by the CPU. The communication done by the GPS to the CPU is done at 3.3 V. This

voltage is made by an internal voltage regulator so it will not need to receive this from the

voltage regulator subsystem. All power used for the GPS is from the CPU.


Power systems: KD

        The system’s power will be provided by three 8.5 A/Hr batteries connected in parallel.

The three batteries will each be charged by its own 5 watt solar panel. A controller will be

required for the charging circuit to ensure safe and effective operation. The battery, solar

panel, charging controller, and watertight enclosure are a package from Fondriest

Environmental called the solar power pack (NexSens SP5). This solar power pack is specifically

designed to fit the buoy (MB-300), which is the primary choice for the platform. The buoy is



                                                                                                 14
designed to hold a maximum of three solar power packs. This system will utilize all three

positions on the buoy so that maximum power capabilities are achieved, effects of rate of solar

charging differences are minimized, and allowing the system to still function correctly in the

case of battery and/or solar panel failure. Therefore, 3 solar power packs from Fondriest

Environmental will be required and the relevant specifications and pricing of the solar power

pack is shown in Table 8Error! Reference source not found.Error! Reference source not found..

                                                                    Contents

         This will provide the system with a sufficient amount of power so that the system will

remain within the requirements of being low maintenance; operate for well beyond the

minimal requirement of 6 months of self-sustained operation, according to the manufacturer.

Also, the solar power pack (NexSens SP5) is designed for applications similar to this application,

therefore, weather and constant exposure to water should not create any problems for this

system.


         The power system will provide power to the subsystems listed below in Table 9:

       The solar power pack will provide 12 volts for our system and approximately 25.5 A/Hr

with a load drawing a current of 500 mA and will also be charged regularly via the solar

charging circuit. The electronics of our system will require a range of voltages and will all be

stepped down to the appropriate voltages using common solid state regulators and the

required circuitry for proper operation. All the voltage regulation will be completed on a

custom PCB which will also include the computer subsystem and its supporting circuitry. The

voltages generated on the PCB will be 5 volts and 3.3 volts which can be easily obtained be

voltage regulators such as the L7805 voltage regulator for the five volts and then utilize the five

volts as an input to the LM3940 to achieve the 3.3 volts. Both of these devices are common and

the cost of these parts may be included into a general expense, or electronic components

expense section of the itemized expense list as the components themselves and supporting

circuitry will be approximately $100.00. The transmitter located on the buoy will receive the 12

volts, filtered, from the battery directly. The receiver at the power plant will require a 12 VDC,

and 3.3 VDC source as well, which will be provided by a power supply that rectifies and filters

the 120 VAC at the power plant which will supply a regulated 12 VDC, and 3.3 VDC. The receiver

will be located at the power plant and will require 12 VDC. Other devices being powered at the

plants receiver location will be a 3.3 VDC in order to provide power to the CPU and 5 VDC.

These voltages will be provided by a standard 120 VAC power source at the plant, which will be

converted into a pulsating DC source offering the required voltages. The AC voltage will be

stepped down to an appropriate voltage by a step-down transformer, rectified, filtered, and

regulated using common solid state components. A PCB (printed circuit board) will be required

                                                                                                   16
for both transmit and receive locations. The PCB can either be etched by hand or machined.

However, there is a substantial difference in cost. The price differences will be noted in Table

10, below. A general outline of the costs associated with the power system is located in Table

10.

Long Range Communication: AA


         The transceiver device that will be mounted to the buoy will transmit serial data to the

Southern Illinois Power Cooperative (SIPC) receiver. The device must be accurate to a point that

no data will be lost causing the Southern Illinois Power Cooperative to become in danger of not

being able to provide requested temperature readings taken trough out the year.




                                                                                                                           17
       The CDR-915XL transceiver incorporates all the elements

that are needed to successfully transmit and receive necessary

information to and from the SIPC control room. The distance the

CDR-915XL can communicate between two points is up to 10 miles           Figure 4 Mobile Antenna


when paired with the proper antenna [1]. For this

application the buoy will have a mobile antenna as seen in

Figure 4, while the control room will have a Yagi antenna as

seen in Figure 5 which will be attached to the

communication tower on the power plant. The CDR-915 XL
                                                                 Figure 5 Yagi Antenna
will transmit/receive in the frequency range of 902-928MHz

which is designated for Amateur/Radiolocation by the U.S. Department of Commerce [5]. The

CDR-915XL has also been tested and approved by the department of Federal Communications

Commission (FCC). As seen in Figure 6 the CDR-915XL device is self contained except for an

external antenna. With this if there is ever a need to replace the device it would only require

unplugging it. In Table 11 all necessary accessories are listed that make the CDR-915XL

operational for the project at hand.

Buoy CPU: TP

         A microcontroller is proposed to coordinate the input of the various signals and the

timing of transmissions to the receiver. The CPU will receive the three temperature probes

signals and convert them into a digital signal and correlate them with the GPS information to




                                                                                                       19
give an accurate report of time, temperature and location in latitude, longitude and altitude.

This information will be stored at a minimum every minute in the RAM.

       Approximately every 10 minutes the micro controller will cue the transmitter and send

the stored data to be transmitted. The data will be sent at least 5 times from the transmitter to

the power plant receiver to ensure minimal corruption of the data. Below is the basic block

diagram of the CPU interactions. The GPS receiver is included in the diagram because it will be

soldered to the same PC board as the other CPU components.

$75 to $90 dollars and common electronic components making up the rest of the expense. The

CPU can be put on the same PCU board that the power supply is on to save money and space in

the buoy. The software or the license to burn the instructions onto the chip will not need to

purchased, the Department of Technology already has them.

voltage varied between 0 and 10 Volts. Both of these functions rely heavily on the micro

controller. The error checking will be done in a manner similar to that used by NASA and their

space probes. The buoy CPU will have the transmitter send the same data at least five times

and the micro controller will perform a comparison between the sets of data and forward the

data which matches the most sets of the received sets. This operation will be completed

entirely within the micro controller.

        To facilitate the output required by the power plant the micro controller will serially

send the data to a digital to analog converter. The converter will send the signal to a de-

multiplexer which will be controlled by the micro controller. This will allow the minimal usage

of parts while giving the maximum number of outputs. Below in Figure 8 is a block diagram of

the receiver decoder/encoder. The cost is broken down in Table 13 and total cost is about

                                                                                                  22
$125. Again the micro controller is the most expensive component but the serial digital to

analog converter is priced between 15-25 dollars. This too can also be added to the Power

Supply’s PCU to save space and expense.

Experiments and Data:

Temperature Sensors EB


       Experiments will need to be done to verify that the sensors are operating properly and

providing accurate temperature readings. Multiple tests can be performed after connecting the

sensors to a power supply and then by submerging the sensors underwater and measuring the

analog voltage output with a voltmeter. The voltage read by the meter should be in the range

of 0V to 2.2V and should change proportionally and linearly corresponding to the change in

temperature. These tests should be repeated at several different times when the temperature

is different. Also, a cheap underwater thermometer can be submerged at the same location as

the sensors to compare the results. If the sensors pass all of these tests they should be safe to

use as our source of temperature data for the system.


Power System KD


       Testing procedures for the power subsystem will require testing each output voltage of

the power system to ensure that the measured voltage is within the requirements of the device

being powered. Also, the load current draw will be tested to ensure the power system offers an

adequate amount of current for the given load. Short circuit protection will be included for all

of the power system outputs and will be tested to prevent damage to the power system or

other subsystems

Appendix 2: Communications TP

Updated Objectives’




                                VII
I: Project Primary Objectives:

   1. Meet all recording requirements of Lake of Egypt as required by the Environmental
      Protection Agency (EPA) under the Clean Water Act. The requirements are as followed.
          a. Monitor the temperature of the lake water at a given location every hour at the
             edge of the designated mixing zone.
          b. Record this temperature for reporting purposes.
   2. Sensors must report output data in a non-routable analog format. Data may be
      transmitted from the sensor to an intermediary receiver as a digital signal and
      converted by the receiver. Format can be in one of two options.
          a. A voltage output between 0 and 10 volts.
          b. A current between 0 and 20 milliamps.
   3. The system will include a method to determine the sensor position at the time of each
      data point.
   4. Other objectives related to Objective I-1, I-2, and I-3
          a. Sensors must be reliable without attendance for periods of at least 6 months,
             preferably longer.
          b. The components determined most likely to fail shall have a backup, failure to
             report for an hour is out of compliance with EPA permit.
          c. Temperature will be gathered at three depths to ensure an accurate reading of
             the lake water temperature has been recorded. These temperatures will all
             need to be reported to the DCS.
          d. The sensors will report alert operators to any faults.
          e. Upon sensor fault, the system shall have a method to provide a basic indication
             of the fault cause.
          f. The system will make the change from primary to backup automatically, without
             the intervention of operators.
          g. Included in the project proposal should be a of Tier III replacement parts needed
             to ensure continued operations.
          h. Parts shall be able to be changed out with the sensor in place without
             interrupting operations for longer than 45 minutes.

II: Project Secondary Objectives

       1. Record the following basic weather data at the lake level.
             a. Air Temperature
             b. Humidity
             c. Air Speed

                                                                                           VIII
               d. Air Flow Direction

III: Project Tertiary Objectives

       1. Provide a duplicate data collection sensor to record the intake water temperature.
             a. Sensor must meet same reliability as sensors from primary objectives.
             b. Sensor should have a method to prevent it from passing into the condenser
                 in the event of mounting failure.
       2. Record and monitor additional weather data.
             a. Solar incidence at lake level.
             b. Precipitation rate at a given time.
       3. Record flow rate and direction of the lake water out of the mixing zone at the
          primary monitoring point.
       4. Provide a temperature sensor at the effluent point of the condenser water.
