Embodiment 1
[0036] Embodiment 1: This embodiment provides a method for detecting the operating state of the sliding door lock in the platform door system. The detection method detects the operating state of the sliding door lock in the platform door system by calculating time, including the following steps:
[0037] When opening the door, record the time when each sliding door lock mechanism of the same type on the whole line network sends out the electromagnet pull-in signal T a , The time to receive the action signal of the lock in place switch T b , to calculate the unlocking time of each sliding door lock ΔT 1 , ΔT 1 = T b - T a ;Divide the unlocking time of the sliding door lock into normal state 1, normal state 2, warning value 1, warning value 2 and fault value according to the length of time, and establish the unlocking time fault with the time as the abscissa and the running state as the ordinate Threshold curve, the curve status is as figure 1 shown.

Embodiment 2
[0048] Embodiment 2: The similarities between this embodiment and Embodiment 1 will not be repeated. The difference is that when the detection requirements cannot be met by the close position switch and the lock position switch, the electromagnet is detected by the door state detection module. Action time of instruction, close limit switch and lock limit switch.
[0049] like Figure 4 As shown in the figure, when the DCU receives the door opening command, it sends the electromagnet pull-in command, and the detection module starts timing when it detects this state; after the electromagnet receives the pull-in command, it controls the lock to unlock, and after the unlocking is completed, the lock position detection switch operates , when the detection module detects the action state of the lock in-position switch, the detection module ends the timing, completes the record of the unlocking time, and uploads the data to the intelligent operation and maintenance host.
