Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. 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. 1, the invention provides a method for dividing a test pull authorization area based on train connection and disconnection, which is applied to a CBTC signal system, and aims to quickly and reasonably determine the length of the test pull authorization area according to factors such as a train length, a test pull length, a parking precision of a connected train, a compression distance of a coupler, a moving distance of the connected train after collision in normal connection and the like in order to consider various factors such as safety, economy, efficiency and the like in order to improve the throughput of the train, and specifically comprises the following steps:
step S1: the connected trains and the disconnected trains are positioned in the connecting and disconnecting area. When the project is configured with the trial pull function, the service parking points of the linking and unbinding area are used as searching starting points, and searching is carried out upwards and downwards according to the directions of the service parking points respectively, so that a trial pull authorization area is generated. Wherein service stops may overlap as long as they contain different attributes, such as service stop type; the connecting and unbinding area with the function is not configured, and after the mechanical hook state is changed, the vehicle-mounted direct control electric hook stretches out.
Step S2: as shown in fig. 2, for an upstream service stop point, the upstream extension length to the service stop point is: the maximum target train connection grouping length of the service stopping point, the stopping precision of the connected train and the maximum test pulling distance correspond to the starting end of the test pulling area. The extension length upstream of the service stop is: and the grouped length of the hung train of the service stopping point- (the compression distance of the coupler, the moving distance of the hung train after being collided in normal hanging and the parking error of the hung train) corresponds to the terminal of the test pulling area.
And the connected train parking error is used for clamping the parking range when the request is started to be sent and connected. And the maximum trial pulling distance is used for immediately triggering the emergency braking to stop and exiting trial pulling when the displacement of the train to be disconnected exceeds the maximum trial pulling distance. The distance moved by the hung train after collision during normal hanging is used for preventing the hung train from canceling the hung request after exiting the hung area in the hanging process, and the ZC cancels the hanging-off authorization, so that the hanging-off train is misjudged to be failed in hanging-off.
Step S3: as shown in fig. 3, for a downstream service stop point, the downstream extension length to the service stop point is: the maximum target linking group length of the service parking spot, the linked parking error and the maximum trial pull distance correspond to the terminal of the trial pull area. The downstream extension length to the service stop is: the grouped length of the linked trains of the service stopping point- (the compression distance of the coupler, the moving distance of the linked trains after being collided in normal linking and the linked parking error) corresponds to the start end of the test pulling area.
Step S4: and deleting the test pull authorization area which does not meet the condition, namely, the test pull authorization area which does not exist in the linking and unbinding area partially or completely.
The invention has been put into practical use, and the division of the trial pull authorization area improves the accuracy of train linking and unbinding.
