Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.
As shown in fig. 4, the method for detecting linkage control failure of platform doors in urban rail transit according to the present invention comprehensively determines the cause of the linkage failure by collecting the state of each specialty and command operation information and combining the current linkage failure, and specifically comprises the following steps:
s1, establishing a normal and fault model for linkage control of a platform door;
s2, acquiring a control command and state interface information of the platform door;
s3, performing cooperative monitoring based on the model established in the S1 and the information acquired in the S2;
s4, comprehensively judging the reason of linkage control failure;
and S5, giving corresponding risk prompt according to the reason of linkage control failure.
The specific processes of the steps are as follows:
1) Establishing a platform door normal work flow model, as shown in the model of fig. 1:
in the process that a train enters a station and stops at the station, once the train is stopped stably and accurately at the station, the train sends a door opening command and synchronously sends the door opening command to the trackside signal system, and the trackside signal system sends the door enabling and door opening command to the station door based on the vehicle-mounted command; and the platform door system receives the platform door opening command, drives the door control motor, sends the opening state to the trackside signal system, and finally forwards the opening state to the vehicle-mounted signal system so as to judge whether the linkage opening of the vehicle door and the platform door is normal.
When the train finishes the operation of getting on and off passengers, the train prepares to leave the station, and under the condition that the train is stably stopped at the station, a command of closing the train door is sent to the train, and a command of closing the door is synchronously sent to a trackside signal system, and the trackside signal system sends a command of forbidding the door and closing the door to the station door based on the vehicle-mounted command; and the platform door system receives the platform door closing command, drives the door control motor to control the platform door to close, sends the closing state to the trackside signal system, and finally forwards the closing state to the vehicle-mounted signal system so as to judge whether the linkage closing of the vehicle door and the platform door is normal.
2) Establishing a platform door linkage fault model as shown in the model of fig. 2: two types of platform door linkage fault conditions are distinguished. The first method comprises the following steps: when no train is arranged in the line area where the platform door is located, the state of the platform door is changed; second, the train stops at the platform, and although the train issues a platform door control command, the train receives a correct feedback status of the platform door system within a specified validity period. According to the two types of conditions, the condition for judging the linkage fault state of the platform door is given:
and when any one of the following conditions is met, judging the platform door linkage fault state:
1. the platform rail is free and the platform door is opened, or
2. Detecting that the platform door is in the open state within the valid period of the door closing command (predefined time 60 s), or
3. The platform door is detected to be in a closed state within the valid period (predefined time 6 s) of the door opening command.
In the platform door linkage fault recovery scene, when the platform door and the train are both in a safe state, the risk between the platform door and the train door needs to be confirmed manually to be relieved, and after a confirmation command is sent out, the platform door linkage fault state can be recovered.
And when all the following conditions are met, judging that the platform door linkage is in a normal state:
1. the platform door is in a closed state, and
2. has not received a door open command, and
3. a manually acknowledged fault recovery command is received.
3) Through cross-professional collaborative analysis of the cause of the platform door and vehicle door linkage failure, an activity diagram model is established as shown in fig. 3:
when the linkage failure of the platform door and the vehicle door occurs,
1. and if the activated state of the manual control platform door button 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 fault is that the platform door system receives a manual control platform door command with higher door control priority level, so that the vehicle door and the platform door linkage control are disabled.
2. And if the platform door end door is in an 'automatic' mode and the 'interlock release' button activation state is acquired from the platform door system, determining that the reason of the platform door linkage fault is that the vehicle door and platform door linkage control failure is caused because the platform door system receives a manual bypass platform door control command.
3. If the platform door end door is in an 'automatic' mode and the 'interlock release' button is not pressed after the train is stopped and allowed to stop stably and is collected from the platform door system, the cause of the platform door linkage fault is determined to be 'platform door out of control'.
4) And giving corresponding risk prompt according to the reason of linkage control failure:
when the linkage of the platform door and the vehicle door fails, the risk of casualties caused by the fact that passengers are clamped possibly occurs, therefore, the fault cause of the platform door is identified through a cross-professional collaborative analysis method, the corresponding emergency plan is started based on the corresponding risk prompt, and the platform door is recovered to be in a normal state through manual confirmation after the corresponding risk is guaranteed to be relieved.
According to the invention, the platform door cross-professional collaborative analysis method is used for quickly positioning the fault and implementing corresponding maintenance, and meanwhile, the matched emergency plan is started quickly to relieve the risk, so that the operation influence degree on the train is ensured to be lowest.
