Abstract

The invention relates to an SPKS switch box jointly controlled with a traffic signal system and an access control system, including a box body, an outer door and an inner door. There is an electric mortise lock for the inner door; the locking space of the inner door is also equipped with a PLC electric control system, the PLC electric control system and the electric mortise lock for the inner door, the travel switch for the inner door set on the inner side of the inner door, and the outer door set on the outer side of the inner door The travel switch signal is connected, and the PLC electric control system is also connected with the driving signal system and the access control system. The invention interconnects the SPKS switch with the driving signal system and the access control system to form logical control, adds technical card control to the existing process card control, and realizes safety interlocking technically, instead of only relying on the quality of relevant personnel , to reduce operational security risks.

Description

technical field [0001] The invention relates to a vehicle body surface protection accessory, in particular to an SPKS switch box which is jointly controlled with a driving signal system and an access control system. Background technique [0002] The parking lanes of the subway parking train inspection garage are usually divided into several maintenance zones, each zone contains multiple lanes, and each lane contains one or two parking bays. In order to ensure the safety of maintenance personnel when working in the maintenance area, each maintenance area is provided with a SPKS switch (Staff Protection Key Switch, staff protection switch), which is connected to the driving signal system. When the SPKS switch is activated, the driving signal system does not allow Corresponding to the maintenance area to enter and exit the vehicle. SPKS switches are usually installed in a lockable SPKS switch box, located in the DCC (Depot Control Center) or near the maintenance area. The ins...
