According to many temperature measuring points, the large delay, nonlinear and time-varying characteristics of the temperature control system of test bench for thermal insulating property, By combining fuzzy-PID control technology with Zigbee WSN technology, a design scheme of the automatic control system of test bench for thermal insulating properties of building doors and windows is put forward, which is low-cost and high precision. The microprocessor of sensor node adopts CC2530 wireless MCU. The system adopts Zigbee wireless network and RS-485 bus to transmit digital temperature and humidity signals, and is no wiring, intermediate links are lessened, transmission error is reduced and temperature measuring accuracy is improved. By adopting Fuzzy-PID control, the self-adaptability of controller and the precision of temperature control is improved.

The new fuzzy PID control system presented in this thesis is a combination of the models used in traditional temperature control system and Dual cross limiting temperature control system that took problems such as the slow response and overshoot of furnace temperature caused by the drastic change of the value of gas and the pressure in to account. The fuzzy PID control system helps to conquer the drawbacks of Poor dynamic tracking performance and has the distinction of being flexible, quick and adaptable. It is also proven by practice that, it is environmental friendly and energy-saving with the high-accuracy and lower consumption of this new control system.
