Abstract

The utility model provides a train control and monitoring system based on two-level bus, wherein the improvement of the system is that: each train comprises two central control units, a plurality of train sub-systems, and a CAN train bus which penetrates through the entire train; all sub-systems on the train communicate with one of two central control units on the train through the CAN train bus; two redundant WTB buses are arranged between the trains; the WTB buses and the CAN train bus realize information exchange through a gateway. The central control units are redundant with each other so as to ensure that train control and diagnosis system normally operates; the trains are connected by the two redundant WTB buses when the trains are hung together; all data can be simultaneously transmitted through the two WTB buses; the information transmission between the trains is not affected by the fault of one bus and the master processor of each hung train is independent with each other without effect to each other.

Description

Train Control and monitored control system based on the two-stage bus

Technical field

The utility model relates to the control and the monitored control system of a kind of control and fault localization system, particularly a kind of inter-city train.

Background technology

Present inter-city train is a complication system that a plurality of decentralised controls unit is arranged; The task of Train Control and monitored control system is for the driver effective train status information to be provided in train operation, maintenance period; Send some control commands simultaneously, the control part mobile unit.The inter-city train network mainly adopts the MVB bus at present; Its core technology is grasped by several international famous big company always; Present home market is almost these companies and monopolizes, thereby buying, maintenance and replacement cost are very high, and it is high to cause the user to run with maintenance cost.

Summary of the invention

The utility model technical matters to be solved is, overcomes the above-mentioned shortcoming of prior art, and a kind of Train Control and monitored control system based on the two-stage bus is provided, characteristics such as it has the reliability height, and equipment cost is low, maintainability is strong.

In order to solve above technical matters; Train Control and monitored control system that the utility model provides based on the two-stage bus; It is characterized in that: every train comprises two Central Processing Unit (CPU)s, some train subsystems and a CAN train bus-line that runs through full car, and subsystems all on the train are all through a communication in two Central Processing Unit (CPU)s on said CAN train bus-line and this train; Be provided with two mutual redundant WTB buses between train and the train, said WTB bus realizes information exchange through gateway and CAN train bus-line.

Under the normal circumstances; A primary processor (Central Processing Unit (CPU)) control train network; Another primary processor is in the state of intercepting; When controlling the primary processor fault of train network, the primary processor that is in the state of intercepting will be taken over the fault primary processor immediately automatically, thereby guarantee that Train Control and diagnostic system normally move.Train joins when hanging, and adopts two mutual redundant WTB buses between train and the train, and all data can be transmitted through two WTB buses simultaneously, and a bus failure does not influence the information transfer between the train.And each primary processor that joins the extension train is relatively independent, is independent of each other.

Further, the information between train and the train exchanges through the WTB bus, is provided with the driver's cab touch sensitive display unit in the two ends driver's cab of every train, in order to showing the relevant information of all trains, and all trains is controlled and is managed.

It is thus clear that, the utility model ingenious conception, reliability height, equipment cost is low, maintainability is strong.The utility model will be widely used in field of track traffic, have good market outlook.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is based on the Train Control of two-stage bus and monitored control system composition frame chart.

The specific embodiment

As shown in Figure 1; Present embodiment is based on the Train Control and the monitored control system of two-stage bus; Its improvements are: train T1, T2, T3 include two Central Processing Unit (CPU)s, some train subsystems and a CAN train bus-line that runs through full car separately; Subsystems all on the train are all through a communication in two Central Processing Unit (CPU)s on said CAN train bus-line and this train, and the arbitrary node fault can not influence the normal operation of whole network; Be provided with two mutual redundant WTB buses between train and the train; Has the automatic network-building function; Said WTB bus realizes information exchange through gateway and CAN train bus-line, and data can be transmitted through two WTB buses simultaneously, and a bus failure does not influence the information transfer between the train.

Information between train and the train exchanges through the WTB bus, is provided with the driver's cab touch sensitive display unit in the two ends driver's cab of every train, can show the train failure message, also can sending controling instruction.Join the information of hanging train and exchange, show the relevant information of all trains at the touch display of driver's cab through the WTB bus; In addition, the driver can carry out part control and management to all trains (comprise joining and hang train) through the touch display that activates driver's cab.The failure message that driver's cab shows mainly contains primary processor to be provided.

Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
