Project Introduction

Railway is the foundation of social and economic development. With the sustained and rapid development of our country's economy, people's requirements for railway transportation speed are also increasing. Contact Network isolation switch is an important device for electrified railway electric traction power supply. Its main function is to isolate faults, work in sections and change operation mode. The screen control terminal RTU is responsible for centralized monitoring of the terminal station and the section isolation transformer, real-time acquisition of the operation status of the isolation transformer, real-time data communication with the power supply SCADA dispatching center, reporting the operation data of the field equipment to the dispatching center, and executing the control, parameter, setting and other commands issued by the dispatching center.

There are a large number of contact Network switches with wide distribution in the hub station. If manual transmission operation mode is adopted in the site, it would be very inefficient and restricts the improvement of the automation level of the whole contact Network line. In order to implement the remote centralized monitoring of these switches, our customer choose our Touch Think 12 inch industrial tablet PC, and use a serial port to connect the I / O version to display the switch status, which integrates the video monitoring system of the isolation switch, solves the problems of remote monitoring and video monitoring, and enables all the isolation switches in contact Network line to have the remote viewing function, so as to improve the system security and efficiency.
