Overview Background Project Summary Physical System Microcontroller and Touch Screen LCD Control System Conclusions

Slide 3

Background Intels problem Many testing machines Machines are too specific Want to expand to be able to test different types and sizes of processor with one machine Solution to Intels problem Build a new system that uses heated water to test processors under high temperatures New system will be able to test a variety of processors

Slide 4

Project Summary Build a heated water delivery system Use a microcontroller to read sensors Microcontroller sends commands to pumps, heater, and valves Create a stand alone control system Use a touchscreen LCD to create a easy to use HMI

Slide 5

Physical System Made up of one pump that circulates water though the heater and chiller. Valves control where a major portion of water runs. Sensors are used throughout system to gain information from the circulated water

Slide 6

Microcontroller Reads sensors and uses values to control physical system Values read from sensor are sent over serial to LCD to be displayed Interrupt driven control system uses sensor inputs to drive both heater and pump values

Slide 7

Touch Screen LCD Menus that allow users to easily navigate through and change values Each menu is specific to different parts of the physical system. Set point menu allows users to change the temperature of the water and the flow or pressure the pump outputs An easy to use key pad allows users to enter new values PID Values Set Point Values MAIN MENU Temp: 12.75 Set Point: 22.0 Flow: 2.0 Set Point:2.5 Pressure: 2.15 Set Point: 3.4 Current PID: FLOW Menu
