Embodiment 1

[0058] A train control system suitable for retrofitting existing lines, including ground equipment and on-board equipment. Among them, the ground equipment such as Figure 1a shown, including, interlocking system, parallel port LEU, and active transponder installed at the station and connected in sequence. The interlocking system can be a computer interlocking system or a relay interlocking system, both of which have an execution relay group, and the parallel port LEU can be connected to the execution relay group through the parallel port I / O (input / output). The parallel port LEU collects the contact status of the interlocking system from the parallel port I / O, and combines the contact status of the interlocking system into an entry selection condition (it can be considered that the combination relationship of the contact status of the relevant switch representing the relay group represents the entry route selection condition), send the station message stored in the parallel p...

Embodiment 2

[0076] During construction along the railway, it is necessary to temporarily limit the speed of the trains passing through the construction section of the railway to ensure the safety of construction personnel and trains. How to safely set a temporary speed limit on a transportation route that does not exceed 160km / h is a difficult problem. The existing existing cable car system is set up by IC card, and the temporary speed limit information is compiled in advance, and then burned into the IC card. Insert the vehicle control system interface (generally set on the DMI), and import the data into the control system (LKJ for the C0 system). Usually a large construction plan is a monthly plan, such as submitting the construction plan for the next month in the middle of each month; in actual implementation, it can be required to report the construction plan for the next week every week to determine the temporary speed limit. How long to download the temporary speed limit informatio...

Embodiment 3

[0086] As a more optimized solution of the second embodiment, the updated temporary speed limit information is sent to the in-vehicle device only when the temporary speed limit information is updated.

[0087] Specifically as Figure 1b As shown, a "temporary speed limit message update button" is set at the station to select the "updated" state and "not updated" state of the "temporary speed limit message update" status bit. It can be considered that these two states are represented by a binary "temporary rate limit message update" status bit, for example, "0" represents the "unupdated" state, and "1" represents the "updated" state. The "temporary speed limit message update button" can be pressed by the station attendant when the temporary speed limit information is updated.

[0088] The initial status bit of "temporary speed limit message update" is "not updated"; when the temporary speed limit server updates the temporary speed limit message, the station attendant can press...

Abstract

The invention relates to a train control system applicable to the transformation of existing lines, which includes ground equipment and vehicle equipment. The ground equipment includes an interlocking system installed at the station and connected in sequence, a parallel port LEU and an active transponder; the parallel port LEU combines the contact states of the interlocking system into route selection conditions, and sends the station message to The corresponding active balise; when the active balise has a train passing through its scope, it will send the corresponding station message to the on-board equipment of the train. The on-board equipment includes BTM, BTM antenna, train overspeed protection system; BTM receives the station message sent by the active balise when the train passes the range of the active balise, and sends the station message to the train overspeed protection system Subsequent processing. The invention sends route information to the vehicle-mounted BTM through the station message, so that the driver can directly obtain the correct route information, avoiding the risk of train entering the station caused by the wrong route information selected by the driver's misoperation.

Description

technical field [0001] The invention relates to the field of train control in the railway industry, in particular to the field of train operation control systems and methods suitable for the reconstruction of existing lines. Background technique [0002] With the continuous improvement of the national economy's requirements for railway transportation, the requirements for railway train operation management and safety control are also constantly upgraded. The China Train Operation Control System (CTCS) is divided into different levels according to the train speed and the demands of railway operation. Among them, my country's main railway lines (existing railway lines) are CTCS-0 (referred to as C0), and the train running speed is below 160km / h. Circuits, interlocks and automatic blocking devices are used as ground equipment. In the C0 system, when the train is running, it relies too much on the driver's operation, which is labor-intensive, and the most important thing is low...
