In order to effectively correct the temperature error curve of aeroengine bearing, obtain accurate temperature measurement results and fully prolong the life cycle of engine components, an aeroengine bearing temperature real-time monitoring system based on wireless sensor is designed. The output power in the JTAG serial port circuit is distributed to the power concentrator and ARM wireless sensor elements according to the actual application requirements. With the help of the temperature acquisition node chip, the underutilized power signal is integrated and stored in the temperature sensing signal coordinator to complete the hardware development of the real-time temperature measurement system. According to the constraint standards of ZigBee protocol stack and Z-stack protocol stack, determine the calculation results of temperature threshold, improve the timing conditions of measured temperature data, and collect aeroengine bearing temperature data. Then, according to the arrangement of temperature measurement nodes, the modeling and processing of engine bearing temperature measurement data are implemented, and the design of aeroengine bearing temperature real-time monitoring system based on wireless sensor is completed. The experimental results show that under the action of wireless sensor elements, the temperature error curve of aeroengine bearing is well corrected, and the obtained temperature measurement data really fits the actual situation, which can play a certain role in prolonging the life cycle of engine elements.
