[0002] Subway electromechanical equipment is an essential and important part of the subway system. They are responsible for ensuring the normal operation of the subway and stations and the safe and comfortable travel of passengers. Generally, they include ventilation equipment, water supply and drainage equipment, power supply equipment, transportation equipment, guiding equipment, and communication equipment, which are arranged along the subway line during the subway line laying process. The traditional maintenance mode mainly relies on regular maintenance plans, but it is difficult to accurately predict when the equipment will fail. With the development of technology, the equipment health management system has gradually been introduced into the maintenance and management of subway electromechanical equipment. Existing management systems for subway electromechanical equipment can basically meet the daily use requirements, but there are still certain deficiencies. Firstly, most of the acquisition terminals of existing subway electromechanical equipment management devices are fixed around the equipment. In order to ensure the comprehensiveness of monitoring, multiple arrangements are required along the line, increasing the operation and maintenance management costs. Secondly, the support structure of existing management devices is single, and the device is prone to breakage of the support part when impacted, thus affecting the service life of the device. Thirdly, existing management devices require on-site circuit debugging and assembly, and the installation and disassembly process of the monitoring terminal is cumbersome, thus increasing the labor intensity of maintenance personnel. Therefore, it is necessary to design a comprehensive monitoring and management device for subway electromechanical equipment based on remote visualization. Summary of the Invention

[0020] Working principle: When in use, the top guide rail 27 and the rolling support 20 respectively provide limit support for the side support plate 25 at the top and bottom.
