Design Of Indoor Environment Control System In Thermal Power Plant Control Building

Thermal power plant is the layout of electrical equipment and thermal equipment of the building,is the control center of the whole thermal power plant,for the normal operation of the entire thermal power plant has a vital role.Centralized control building good indoor environment to ensure the normal operation of the device in the system to ensure the operators to concentrate on efficient and concentrated on the system control has a very important significance.In this thesis,we mainly study the design of the measurement and control system based on the three parameters of indoor temperature,humidity and light intensity.Due to the centralized control of building interior space larger,the temperature and brightness distribution difference obviously,the short distance wireless communication technology ZigBee networking technology,can flexibly realize acquisition and adjust the control in different spatial locations in the building temperature and the brightness of the light.In the data acquisition of the lower position machine and control of central air conditioning each tuyere gate open degree of the lower position machine and adjusting each of the brightness of the lamp tube lower position machine,respectively using the CC2430 chip as the core components,temperature measurement circuit,humidity measurement circuit,optical measurement circuit design and air conditioning outlet gate control circuit design and lighting control circuit design.Part of the PC to am335 x processor as the main control chip,through the ZigBee communication gets lower position machine gathering of temperature,humidity and light intensity data,respectively through the fuzzy PID control algorithm to calculate the corresponding control command value,and through the ZigBee communication channel sent to actuator corresponding lower machine,thus achieving control regulation of building temperature,humidity and brightness of the lamp tube.Through the debugging and testing of the system design results,the design of the thermal power plant control building indoor environment to achieve a standard of indoor environment control system.
