Problems solved by technology

Therefore, when wireless communication cannot be performed or a vehicle without a wireless device, such as a maintenance locomotive, travels within the wireless train control system, there is a problem that the position of the vehicle cannot be grasped.
[0009] In spite of this, once a vehicle breaks down or a maintenance vehicle is running, if the wireless train control system is stopped, it will have a great impact on the operation of the train

Embodiment Construction

[0046] Below, through Figure 1 to Figure 6 One embodiment of the present invention will be described. First of all, the wireless train control system of the present invention will be described, as an example of which the overall functional outline is as follows figure 1 shown.

[0047] Such as figure 1 As shown, the linkage device 1 has a route control unit 11 and a train online detection unit 12, and has a route setting device 5 and a physical detection device 6, and an IF (Interface) with the ATP (Automatic Train Protection) ground device 2 ).

[0048] The ATP ground device 2 has a train control unit 21 and a train online detection unit 22 , and has an IF with the ATP on-board device 3 via the linkage device 1 and the wireless device 4 . The ATP on-vehicle device 3 has a brake control unit 31 and a position detection unit 32 , and has an IF with the ATP ground device 2 via the wireless device 4 .

[0049] The train on-line detection unit 12 of the linkage device 1 reco...

Abstract

The invention provides a control system for CBTC train. In the control system for CBTC trains, a backup system which can minimize the impact on the operation of a train under the condition that a system is not entirely shifted to a backup system is needed, when ground devices can not access the location of the train, such as train failure or a train used for maintenance. The control system can perform a communication-based train control (CBTC) on CBTC trains through simultaneously use of a backup route and a CBTC route, when a non-CBTC train (non-T1-T3) (a train having communication failure or a train used for maintenance) is in operation, so as to minimize the impact on operation of T1-T4 trains. Namely, a backup zone is defined, and non-CBTC trains and CBTC trains continue to operate.

Description

technical field [0001] The present invention relates to a wireless train control system. In the APT ground device that receives the position information from the train via wireless to perform train online detection, the wireless train control system enables non-wireless trains and installations that cannot detect the position through wireless Wireless trains (CBTC-controlled trains: Communication Based Train Control) run safely within the same line area at the same time. Background technique [0002] In consideration of the reliability of wireless communication, many users have put forward the requirement of having a backup system in case of wireless failure in the wireless train control system. However, from a cost point of view, it is unrealistic to install two sets of systems, a wireless train control system and a backup signal safety guarantee system, in a new line. Therefore, the equivalent of the current ATC / ATS (Automatic Train Control / Automatic Train System) securit...
