In addition, using the touch screen monitor, reliability and flexibility of the electric system is improved.

Abstract: With the continuous development of milling machine, the normal milling machine was not suitable with modern processing. In order to adapt to the requirements of modern production process and quality, the electrical control system of milling machine need be improved. The electrical control system and circuit of X62W milling machine is analyzed and designed. The PLC program is compiled. All of it is proved to be reasonably and feasibly based on the experimental results.

Abstract: This paper is to present a fault diagnosis method for electrical control system of automobile based on support vector machine. We collect the common fault states of electrical control system of automobile to analyze the fault diagnosis ability of electrical control system of automobile based on support vector machine. It can be seen that the accuracy of fault diagnosis for electrical control system of automobile by support vector machine is 92.31%; and the accuracy of fault diagnosis for electrical control system of automobile by BP neural network is 80.77%. The experimental results show that the accuracy of fault diagnosis for electrical control system of automobile of support vector machine is higher than that of BP neural network.
