The fault diagnosis method of filling machine mechatronics system based on single chip microcomputer is studied to improve the fault diagnosis accuracy of filling machine mechatronics system.The TMS320C54X single-chip microcomputer is selected as the core processor of the filling machine mechatronics system.The TMS320C54X single-chip microcomputer uses the built-in intelligent processing model to preprocess the operation signal of the filling machine mechatronics system collected by the sensor, filter and process the collected signal, and select the EMD decomposition method to complete the processing.After filtering the processed signal, the fault signal feature vector of the filling machine mechatronics system is extracted, the GRNN neural network is selected to realize the fault diagnosis based on the extracted fault feature vector, and the CAN bus communication method is used to transmit the fault diagnosis result to the filling machine mechatronics system’s remote control center to realize fault diagnosis of filling machine mechatronics system.The experimental results show that the method can effectively diagnose different types of faults in the mechanical and electrical integration system of the filling machine, the fault diagnosis accuracy is higher than 98%,and the average fault diagnosis time is less than 220 ms.
