[0002] The railway electrical department is an important organization in the railway system. It is mainly responsible for managing and maintaining the ground signals, locomotive signals and turnouts of trains during operation. In layman's terms, it is the unit responsible for the "traffic lights". Its responsibilities include maintaining signal equipment to ensure normal display of signals, maintaining switch machines and turnouts to ensure normal turnout operation, and ensuring the normal operation of trains.

[0003] At present, the terminal equipment used in the railway electrical field operation safety monitoring system is usually assembled in a shell during actual use on site to prevent dust from adhering to the shell and causing short circuits in the equipment, resulting in interruption of the monitoring system, etc. However, after being assembled in the shell, the shell is opened with tools such as screwdrivers every time it is inspected, and then the shell is installed again after the inspection. The inspection operation is not convenient enough, which greatly reduces the inspection efficiency of the terminal equipment.

[0030] The Beidou high-precision personnel positioning terminal can realize high-precision position feedback and has the function of receiving safety warning information broadcast by the dispatching center; develop high-precision GIS maps to provide a time and space benchmark for the entire scene, all elements, and the entire process for system platform development; develop an automated early warning system that can calculate and judge the card control management of the time and space relationship between personnel and skylights in real time, and can push relevant early warning reminders to the background personnel terminals in a timely manner through the system.
