Description
Technical Field
The invention belongs to the technical field of urban railway vehicle transportation, and particularly relates to a method for remotely relieving normal braking and not relieving braking.
Background
The most used braking method is used for parking the train in the service braking mode when the urban railway vehicle operates, when the service braking is not relieved, a driver is prompted on a cab monitoring screen HMI, the driver needs to observe more contents when the driver is on the front line and operates, a certain time is needed when the driver finds that the action is not relieved, after the train is temporarily parked, the air braking isolation plug door of the vehicle is not relieved in the corresponding carriage, the front line operation efficiency is reduced, the wheel set and the basic braking unit of the bogie are found to be damaged greatly at a later time, and the wheel set and the braking brake pad or the brake shoe need to be replaced seriously.
Disclosure of Invention
The invention aims to provide a method for simply, safely and reliably realizing the remote release of a service brake non-release brake control unit of a train control center without adding a train configuration scheme, and improve the front line operation efficiency and the train availability.
In order to achieve the above object, the present invention provides a method for remotely controlling service brake non-release braking, which is characterized by comprising the following steps:
1) the brake system detects the fault information that the common brake of the train is not released, and reports the fault information to the train signal system, the train control network system and the operation control center.
2) When the center receives the prompt of not relieving the brake, the dispatcher sends a releasing instruction of the wire network control center to a train signal system of a corresponding vehicle through a signal system LTE antenna by operating a forced releasing brake soft button of the corresponding vehicle in the control interface;
3) after receiving the command, the train signal system verifies whether the service braking unreleasing fault occurs, if so, the train signal system sends the command to a train forced release service braking command line through a hard line, and simultaneously sends the command to a train control network system through a train control network;
4) a hard wire forced release common brake instruction is transmitted to an IO module of a train control network system;
5) the train control network system receives a hard wire forced service brake release instruction and compares the instruction with whether the vehicle receives a service brake unreleasing fault or not, and if the unreleasing fault occurs, a hard wire release signal is output to a corresponding brake system;
6) the brake system receives a hard-wire forced release service brake instruction, and the service brake is forcibly released under the braking condition.
The invention does not need to add a scheme of train configuration, is a simple, safe and reliable control method for realizing the remote release of the common brake of the train by the center, is convenient to operate, can realize the release of the common brake without stopping and the release of the fault, and can improve the positive line operation efficiency and the availability of the train.
Drawings
FIG. 1 is a control logic diagram;
fig. 2 is a circuit for train enforcement of a forced-release service brake control.
Detailed Description
Referring to fig. 1, the invention comprises a wire network control center dispatcher, a wire network control center human-computer interface, a train signal system, a train control network system and a brake control system, and realizes the purpose of relieving service brake without stopping and relieving faults by the system, and specifically comprises the following process steps:
1) service brake non-release fault uploading
The brake system identifies that the common brake of the vehicle does not relieve the fault, the common brake is sent to a train control network system through a train control network, the train control network system transmits information to a train signal system, and then the common brake does not relieve the fault and gives an alarm through a signal system transmission channel to a network control center (OCC).
2) The central dispatcher gives a forced relieving instruction
The train network control system identifies that the service braking does not release the braking control unit and outputs a hard wire signal to the corresponding braking control unit, and the braking control unit executes forced release.
Referring to fig. 2, the service brake non-relief fault is transmitted to the center through the network, and the central remote forced relief service brake command is sent to the train signal system through the signal channel from the wire network center, and is sent to the network system IO module through the hard wire and is transmitted to the brake control unit through the diode. The relieving function is realized through a train signal system, a train control network system and a hard wire, and the instruction safety is ensured.
