Abstract

The invention relates to an SPKS switch box jointly controlled with a driving signal system and an access control system,. The SPKS switch box comprises a box body, an outer door and an inner door, anSPKS switch is located in a locking space of the inner door, the outer door is provided with an outer door mechanical lock, and the inner door is provided with an inner door electric mortise lock; aPLC electric control system is further arranged in the locking space of the inner door, the PLC electric control system is in signal connection with the inner door electric mortise lock, an inner doortravel switch arranged on the inner side of the inner door and an outer door travel switch arranged on the outer side of the inner door, and the PLC electric control system is further in signal connection with a driving signal system and an access control system. The SPKS switch is in signal interconnection with the driving signal system and the access control system to form logic control, and technical control is added on the basis of existing process control, so that safety interlocking is realized technically instead of only depending on the quality of related personnel, and the safety risk of operation is reduced.

Description

technical field [0001] The invention relates to a car body surface protection accessory, in particular to an SPKS switch box for joint control 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 spaces. In order to ensure the safety of the maintenance personnel when working in the maintenance area, each maintenance area is equipped with a SPKS switch (Staff Protection Key Switch, staff protection switch), which is connected to the traffic signal system. When the SPKS switch is activated, the traffic signal system does not allow Corresponds to the vehicle entering and exiting the maintenance area. The SPKS switch is usually installed in a lockable SPKS switch box, set in the DCC (Depot Control Center) or close to the maintenance area. The interior ...
