In order to solve the problem of wear,pollution or interference caused by contact,and find out the abnormal temperature in time,a temperature monitoring system for the main bearing of marine diesel engine is designed.Based on high frequency radio frequency identification technology,HF RFID temperature sensor is designed to collect the temperature information of main bearings of marine diesel engine in real time.The radial basis function neural network is used to compensate the error of the temperature sensor,and the local reader in the engine room is used to start and receive the main bearing temperature information collected by the HF RFID temperature sensor.Transmitting temperature information to the local PLC control module of the engine room through the local wireless sensor network module of the engine room;The PLC control module protects and controls the temperature of the main bearing of the marine diesel engine according to the received temperature information,and finds out the abnormal temperature in time;Real-time display of main bearing temperature monitoring results by using engine room local display module.The experimental results show that the system can effectively collect the temperature information of the main bearing,compensate the error of the temperature sensor,effectively monitor the temperature of the main bearing of the marine diesel engine and find the abnormal temperature in time.
