Embodiment 1

[0036] Embodiment 1: This embodiment provides a method for detecting the operating state of a sliding door lock of a platform door system. The detection method detects the operating state of a 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 of the whole line network sends out the electromagnet pull-in signal T a 、Time of receiving the action signal of the lock-in-position switch T b , 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 state such 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-in-position switch and the lock-in-position switch, the electromagnet pull-in is detected by the door head state detection module. Command, close position switch and lock position switch action time.

[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 in-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 recording of the unlocking time, and uploads the data to the intelligent operation and mainte...

Abstract

The invention belongs to the technical field of operation and maintenance monitoring, and in particular relates to a method for detecting the operating state of a sliding door lock of a platform door system. The detection method calculates the time difference between the sliding door lock sending the electromagnet pull-in signal and receiving the lock-in-position switch action signal, and the time difference between receiving the close-in-position switch action signal and receiving the lock-in-position switch action signal. The operating status of the sliding door lock in the platform door system is detected. The detection is simple and accurate, which can greatly improve the reliability of the sliding door lock operation and reduce the failure rate of equipment.

Description

technical field [0001] The invention belongs to the technical field of operation and maintenance monitoring, and in particular relates to a method for detecting the operating state of a door lock of a sliding door of a platform door system. Background technique [0002] The sliding door lock device of the platform door system is installed in the top box, located in the upper center of the sliding door position, including the mechanical part and the electronic part; the mechanical part ensures that the sliding door can be locked after running to the locked position, and the electronic part ensures that it can pass the travel switch Feedback the state of the sliding door to the DCU of each door unit. At present, the sliding door lock devices commonly used in the platform door system all use the detection mode of the closed in-position switch and the locked in-position switch to detect the state of the sliding door. [0003] Through years of experience in on-site maintenance o...
