Train tracing running method implemented without secondary railway testing equipment and communication based train control (CBTC) system

The invention discloses a train tracing running method implemented without secondary railway testing equipment and a communication based train control (CBTC) system. The method comprises the following steps that in the train running process, a vehicle on board controller (VOBC) of a train checks whether an object controller (OC) waiting to set up communication connection exists or not in the front of a present running line; if the OC waiting to set up communication connection exists, a communication setting request is sent to the OC; the state of a present jurisdiction is checked after the OC receives the communication setting request; if the OC confirms that the present jurisdiction is in a normal communication state, responses to identification (ID) information of all communication trains in the jurisdiction of the OC are sent to the train; the VOBC can recognize the ID information of a front train adjacent to the present train according to the ID information of all the communication trains; the VOBC sets up communications with the adjacent front train according to the ID information of the adjacent front train and obtains running state information of the adjacent front train; and according to the running state information of the adjacent front train and the running state information of the present train, movement authority (MA) in the jurisdiction of the OC is obtained so as to trace running of the front train. Efficiency of railway transportation can be improved greatly by means of the train tracing running method.

Method of movement authority calculation for communications-based train control system

The present invention discloses a calculation method of movement authority for communications-based train control system, comprising: handling a route information for a train, and determining a searching range of the train according to the route information; initializing the limit of movement authority with the end position of the searching range; searching for static obstacles within the searching range, and successively determining whether each static obstacle meets the safety requirements for train operating, if not, setting the position of the last static obstacle within the searching range as the limit of the movement authority; if so, modifying the limit of movement authority as the end of route having been matched; searching for dynamic obstacles within the searching range, and determining whether there is a train, if so, modifying the end of movement authority as the beginning point of the track section where the train is occupying; if there is no dynamic obstacle within the searching range, modifying the final end is of movement authority as the position of the last static obstacle within the searching range. In accordance with the present invention, it is possible to increase line capacity and improve traffic fluidity for rail transit.

The invention discloses a vehicle monitoring system based on Beidou system. The invention is characterized in that the system is composed of a Beidou ground monitoring centre, a Beidou navigating and locating satellite and a Beidou vehicle-mounted system, wherein the Beidou navigating and locating satellite is dependent on current satellite system built by Beidou network system. The Beidou vehicle-mounted system comprises a Beidou terminal and a train network. The train network is a current TCMS system, wherein the TCMS system comprises a vehicle dragging sub-system, a vehicle braking sub-system, a vehicle signal sub-system and a vehicle broadcasting sub-system. The TCMS system is communicated with a Beidou terminal via an RS232 interface to provide vehicle state information to the Beidou terminal on one hand, and to receive Beidou navigating and locating information, time service information and control instruction from the ground monitoring centre on the other hand so as to control the operation of the vehicle. The Beidou terminal is communicated with the locating satellite. The locating satellite is used for transmitting the locating information and vehicle state information to the ground monitoring centre. The centre is used for transmitting the information to all ground monitoring terminals so that the operated vehicle can be monitored and all operated vehicles can be monitored and controlled.
