All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
As shown in fig. 4, the invention relates to a method for detecting linkage control faults of urban rail transit platform doors, which comprehensively judges the causes of linkage faults by collecting the state and command operation information of each specialty and combining with the current linkage faults, and specifically comprises the following steps:
step S1, establishing normal and fault models of platform door linkage control;
s2, acquiring a control command and state interface information of a platform door;
step S3, carrying out collaborative monitoring based on the model established in the step S1 and the information acquired in the step S2;
s4, comprehensively judging the reason of failure of linkage control;
and S5, giving a corresponding risk prompt according to the reason of failure of linkage control.
The specific process of each step is as follows:
1) Establishing a platform door normal work flow model, as shown in the model of fig. 1:
in the process that the train enters the station and stops at the station, once the train stops stably and is stopped at the station, the train-mounted device sends a door opening command, and synchronously sends a door opening command to a trackside signal system, and the trackside signal system sends door enabling and door opening commands to the station door based on the train-mounted command; the platform door system receives a platform door opening command, drives a door control motor, sends a door opening state to the trackside signal system, and finally forwards the door opening state to the vehicle-mounted signal system to judge whether the linkage door of the vehicle door and the platform door is normal or not.
When the train finishes the operation of getting on and off the bus, preparing to leave the bus, under the condition that the train stops stably and is accurate at a platform, sending a door closing command to the vehicle-mounted device, and synchronously sending a door closing command to a trackside signal system, wherein the trackside signal system sends a door prohibiting and door closing command to the platform door based on the vehicle-mounted command; the platform door system receives a platform door closing command, drives a door control motor to control the platform door to be closed, sends a door closing state to the trackside signal system, and finally forwards the door closing state to the vehicle-mounted signal system so as to judge whether the linkage door closing of the vehicle door and the platform door is normal or not.
2) Building a platform door linkage fault model, as shown in the model of fig. 2: there are two types of station door linkage fault conditions. First kind: when the train is not arranged in the line area where the platform door is positioned, the state of the platform door is changed; second, the train is parked at the station, and the correct feedback status of the station door system is received within a specified period of validity, although the train has issued a station door control command. According to the two conditions, the condition for judging the linkage fault state of the platform door is given:
judging the linkage fault state of the platform door when any one of the following conditions is met:
1. the platform rail being idle and the platform door becoming open, or
2. Detecting that the platform door is in the open state within the validity period of the door closing command (predefined time 60 s), or
3. The platform door is detected in a closed state during the expiration of the door opening command (predefined time 6 s).
And when the platform door and the train are in a safe state, the risk between the platform door and the train door is required to be relieved by manual confirmation, and after a confirmation command is sent out, the linkage fault state of the platform door can be restored.
When all the following conditions are met, judging that the platform door linkage is in a normal state:
1. the platform door being in a closed state, and
2. does not receive a door opening command, and
3. and receiving a manual confirmation fault recovery command.
3) By cross-specialty collaborative analysis of the cause of platform door and door linkage failure, an activity diagram model is built as shown in FIG. 3:
when a failure of the platform door to link with the vehicle door occurs,
1. if the manual control platform door button activation state is acquired from the platform door system and the platform door end door is not in the 'automatic' mode, determining that the reason of the platform door linkage failure is that the platform door system receives a manual control platform door command with higher door control priority, so that the linkage control of the door and the platform door is invalid.
2. If the platform door end door is in an 'automatic' mode and the 'interlock release' button is activated from the platform door system, the reason for the platform door linkage failure is determined to be the failure of the door to platform door linkage control due to the platform door system receiving the manual control bypass platform door command.
3. If the platform door end door is in the "automatic" mode and the "interlock release" button is collected from the platform door system and has not been pressed after the train is stopped and stabilized, then the reason for the platform door linkage failure is determined to be "platform door out of control".
4) And giving a corresponding risk prompt according to the reason of failure of linkage control:
when the platform door and the vehicle door are in linkage failure, risks of casualties caused by clamping passengers can occur, so that the fault cause of the platform door is identified through a cross-specialty collaborative analysis method, a corresponding emergency plan is started based on a corresponding risk prompt, and after corresponding risk relief is ensured, the platform door is restored to a normal state through manual confirmation.
According to the invention, the platform door cross-specialty collaborative analysis method is used for rapidly positioning faults and implementing corresponding maintenance, and simultaneously, the rapid starting of the matched emergency plan is started to relieve risks, so that the minimum influence on the operation of the train is ensured.
