Problems solved by technology

Taking a high-speed train depot as an example, the total number of ground signals is 340, and 340 sets of LEU coding equipment and 340 cables need to be paired to connect with 340 active transponders on site, thereby realizing the communication between the ground and locomotives. The cost is too high, and the construction difficulty also increases

Embodiment 1

[0023] The embodiment of the present invention provides a method for controlling the vehicle directly through the signal machine and the active transponder. This method is not only applicable to the shunting protection system of the train, but also suitable for other similar vehicle control occasions that are simply connected with the signal machine. Specifically include:

[0024] The active transponder is connected to the signal machine, and the lighting control conditions are extracted from the signal machine;

[0025] Select the corresponding transponder message from the internal memory according to the lighting control condition;

[0026] After receiving the activation signal of the vehicle equipment, the active transponder sends the transponder message to the vehicle equipment.

[0027] Such as figure 1 As shown, the active transponder is installed in the center of the two rails 10 to 15 meters in front of the signal machine, and is directly connected to the signal mach...

Embodiment 2

[0034] The embodiment of the present invention provides an active transponder applied to the method described in the first embodiment of the present invention, which is obtained by improving the existing "European standard" active transponder, and is applied directly through the active transponder In the method of controlling the vehicle with the transponder and the signal light, such as Figure 4 As shown, the active transponder specifically includes: an interface module for connecting with the signal machine, the lighting control condition extracted from the signal machine; a storage module for storing the transponder message; A judging and selecting module for selecting the corresponding transponder message in the storage module; and a sending module for sending the transponder message to the vehicle-mounted device;

[0035] Specifically, the interface module in the embodiment of the present invention is mainly composed of lightning protection, rectification and filtering, ...

Abstract

The invention discloses a method for controlling a train directly by using an annuciator and an active transponder and the active transponder used for the method, and belongs to the field of railway train operation safety. The method comprises the following steps of: connecting the active transponder with the annunciator, and extracting a lighting control condition from the annunciator; selecting a transponder message to be transmitted according to the lighting control condition; and after the active transponder receives an activation signal of onboard equipment, transmitting the transponder message to the onboard equipment. According to the method and the active transponder, the active transponder is not required to be controlled by a line-side electronic unit (LEU), so that the conventional system is simplified, the construction cost is low, construction is simple, popularization and application are facilitated, and the aims of preventing overrun and realizing the safety protection of the train can also be fulfilled; and meanwhile, the method and the active transponder can be adapted to various types of domestic onboard equipment, and are high in expansibility.

Description

technical field [0001] The invention relates to railway driving safety, and is suitable for the field of safety protection of railway vehicle control and / or shunting operations, in particular to a method for directly realizing vehicle control through a signal machine and an active transponder without using LEU and other equipment. Background technique [0002] The ground electronic unit, referred to as LEU (Line-side Electronic Unit), is an important ground signal device of the contemporary railway train operation control system. The LEU and the active transponder are connected by a special shielded cable. [0003] At present, in my country's high-speed railways, the basic working principle of car control and / or shunting is: the display information of the ground signal machine is used to generate data signals through coding equipment such as LEU at the station, and the LEU is passed through a special cable with a length of 0.5km to 2.5km Connect with the on-site active transp...
