Sinamics S120 is a new drive and control system introduced by Siemens. It can be used to control many types of motors. 　　Its speed regulation function is accurate and reliable. Its powerful positioning function can also realize the absolute and relative positioning of the feed shaft. Siemens S120 single axis controller is applied to the

The use environment of the controller is complex, and the electromagnetic interference will have a serious impact on the performance of the product. Therefore, the EMC design of products can meet the requirements of alarm control. This paper systematically analyses the interference that gas alarm controller may encounter in the course of using, and gives

In Communication Based Train Control (CBTC), the on-board controller plays a key role. It ensures that the train is positioned accurately, always in the safe speed control range, and makes the two-way communication between the train and the ground real-time and efficient. Because of the effect of urban rail traffic environment, the train is adhering

This paper analyses the basic overview of the driver controller, expounds the fault of the driver controller, and finally summarizes the overhaul fault of the driver controller. Through the analysis, we hope to further clarify the problems of driver controller, ensure the normal use of driver controller, and improve the safety and stability of metro

In this paper, a design scheme of RTU controller is proposed to solve the problem that field equipment can not be controlled manually under special circumstances. According to the scheme, the hardware and software of the controller are designed, and the acquisition of field signals and the control of field equipment are realized. The design

Traditional network data fluctuation controllers often have large amount of computation and complex operation, which results in the shortcomings of the controllers themselves, such as short holding time of network non-fluctuating data and large communication error. Therefore, a more intelligent and practical network data fluctuation controller is designed. The designed controller constructs the network data
