Problems solved by technology

This has the following disadvantages: setting a temporary speed limit will cause the signal at the beginning of the route to be closed, reducing the operating efficiency of the train, and the speed limit command is valid once. If multiple trains pass through the same place, it needs to be set multiple times, which is cumbersome and error-prone

Embodiment 1

[0052] see figure 1 , the present embodiment provides a method for temporarily limiting the speed of a train. The method starts at step 101. The interlocking subsystem obtains an information data packet according to the operation information of the train and the real-time state of the track equipment and sends the information packet correspondingly according to the operation information. The above information data packet; wherein, the operation information includes current route information, turnout information, whether to temporarily limit the speed and the temporary speed limit command corresponding to the current route information. In this embodiment, the information data packet is obtained by writing the train operation information and the real-time status of the track equipment into the data packet in a predetermined format by the interlocking subsystem.

[0053]Specifically, the predetermined format is obtained by adding a temporary speed limit related field in an existi...

Embodiment 2

[0066] see image 3 , Figure 4 as well as Figure 5 , image 3 with Figure 4 This embodiment provides a temporary train speed limiting system, including: an interlock subsystem 301 , an LEU subsystem 302 , a transponder 303 and an on-board ATP subsystem 304 . The realization principle of this system is as follows:

[0067] In step 501, the interlocking subsystem 301 writes the running information of the train and the real-time status of the track equipment into a data packet of a predetermined format, obtains the information data packet, and sends the information data packet to the corresponding LEU subsystem according to the operation information. LEU module; wherein, the operation information includes current route information, switch information and a temporary speed limit command corresponding to the current route information.

[0068] In step 502, the LEU subsystem 302 receives the information data packet and converts the format of the information data packet to ob...

Abstract

The invention provides a temporary train speed restriction method. The temporary train speed restriction method comprises the steps of obtaining an information data packet according to train running information and a real-time state of a track device and correspondingly sending the information data packet according to the running information, wherein the running information includes current forward road information, turnout information, the temporary speed restriction situation and a temporary speed restriction instruction corresponding to the current forward road information; receiving the information data packet and performing format conversion on the information data packet to obtain response data packet; obtaining a train running curve according to the response data packet and confirming a driving mode according to the obtained train running curve. By adopting the temporary train speed restriction method, the temporary speed restriction cannot cause closing of a forward road starting-end signal machine, phone confirmation between a watchman and a drive is not needed, the speed restriction instruction is effective for multiple times, multiple-time setting is not required, and the running efficiency of a train is improved.

Description

technical field [0001] The invention relates to a train control system, in particular to a method and system for temporarily limiting the speed of a train. Background technique [0002] In the urban rail transit train control system, the temporary speed limit function under the CBTC control level is realized through the following process: a set of temporary speed limit servers are set up on the entire line, the operator on duty at the center handles the temporary speed limit operation, and the control command is sent through the temporary speed limit server To each ground ATP (Automatic Train Protection, automatic train protection) on the whole line, when the ground ATP subsystem calculates the movement authorization for the train, it will check the movement authorization area. When the range overlaps with the temporary speed limit area set by the center, Send the temporary speed limit information to the on-board ATP device as part of the mobile authorization. After the veh...
