In the embodiment of the invention, the special vehicle-mounted equipment only comprises a train safety monitoring function and an interaction function with ground equipment.
The special in-vehicle apparatus is exemplarily represented by a special in-vehicle apparatus a and a special in-vehicle apparatus B. It should be noted that, a person skilled in the art may set more than two special vehicle-mounted devices in the train control vehicle-mounted device system according to actual needs.
Referring to fig. 1, fig. 1 shows a schematic diagram of a combined train control vehicle device system compatible with a plurality of train control systems according to the present invention. The general vehicle-mounted equipment comprises 10 modules including a train monitoring function, a wireless transmission function, a transponder transmission function, a speed measuring and distance measuring function, a man-machine interface function, a reference time function, a data recording function, a train interface function, a brake interface function and a special vehicle-mounted equipment control function.
The wireless transmission function module is used for wireless data transmission between the general vehicle-mounted equipment and the ground equipment and between the special vehicle-mounted equipment and the ground equipment. The transponder transmission function module is used for receiving the ground transponder message and providing the ground transponder message to the general vehicle-mounted device and the special vehicle-mounted device. The speed and distance measuring function module is used for calculating the position, speed and direction of the train and providing the position, speed and direction to the general vehicle-mounted equipment and the special vehicle-mounted equipment. The human-computer interface functional module is used for realizing human-computer interaction between the general vehicle-mounted equipment and the special vehicle-mounted equipment and a driver. The reference time function module is used for providing system time for the general vehicle-mounted equipment and the special vehicle-mounted equipment.

The train interface functional module is used for collecting train interface input information and providing the information for the general vehicle-mounted equipment and the special vehicle-mounted equipment. The braking interface functional module is used for outputting braking commands to the train through the general vehicle-mounted equipment and the special vehicle-mounted equipment. The wireless transmission function module, the transponder transmission function module, the speed and distance measuring function module, the man-machine interface function module, the reference time function module, the data recording function module, the train interface function module and the brake interface function module in the general vehicle-mounted equipment are all used for sharing by special vehicle-mounted equipment.
In addition, the train monitoring function module is used for realizing the core logic of train safety monitoring based on train data and ground information. The special vehicle-mounted equipment control function module is used for managing all special vehicle-mounted equipment by the general vehicle-mounted equipment; the special vehicle-mounted equipment control function module is a bridge between the general vehicle-mounted equipment and the special vehicle-mounted equipment, and can control the special vehicle-mounted equipment and control right switching between the general vehicle-mounted equipment and the special vehicle-mounted equipment. The train monitoring function module and the special vehicle-mounted equipment control function module in the general vehicle-mounted equipment are not used for sharing by the special vehicle-mounted equipment.
In the embodiment of the invention, one end of each of the special vehicle-mounted equipment A and the special vehicle-mounted equipment B is connected with the general vehicle-mounted equipment through a Profibus (or other buses such as an MVB bus) to share information acquired by 8 functional modules of a wireless transmission function, a transponder transmission function, a speed measuring and distance measuring function, a man-machine interface function, a reference time function, a data recording function, a train interface function and a brake interface function of the general vehicle-mounted equipment. The special vehicle-mounted equipment realizes safety monitoring of the train by processing the acquired information. Meanwhile, the other ends of the special vehicle-mounted equipment A and the special vehicle-mounted equipment B respectively interact with the ground equipment through the special ground information receiving and transmitting unit A and the special ground information receiving and transmitting unit B, and are used for monitoring the safe running of the train on a specific line provided with corresponding ground equipment. The special ground information receiving unit is an information receiving unit which is arranged on special vehicle-mounted equipment and can receive the information of the special line ground equipment, and the special ground information receiving unit can be one unit or a combination of more than two units. For example, the train control system receives ground information, and if only one type of ground information needs to be acquired, one type of special ground information receiving and transmitting unit is used; if two different types of ground information need to be collected, two different types of special ground information receiving and transmitting units need to be used.
The specific lines refer to lines supporting different special train control systems, on which corresponding special ground equipment is installed. For example, if a line is supporting a particular train X, then a particular surface facility L is installed on the surface. When the train needs to enter the line for running, the control right of the vehicle-mounted equipment is required to be converted into the special vehicle-mounted equipment A through ground commands or driver operation, the special vehicle-mounted equipment A can normally receive the information of the special ground equipment L on the line, and the safety control of the train is realized under the support of sharing functions of the general vehicle-mounted equipment.
After the train control vehicle-mounted equipment systems compatible with various train control systems are electrified, the special vehicle-mounted equipment requests to establish communication connection with the general vehicle-mounted equipment, and the general vehicle-mounted equipment receives the requests and checks the system version of the special vehicle-mounted equipment. If the special vehicle-mounted equipment is compatible with the version of the general vehicle-mounted equipment, the general vehicle-mounted equipment and the special vehicle-mounted equipment are successfully connected in a communication way; if the versions are not compatible, the generic vehicle-mounted device refuses to establish a communication connection with the specific vehicle-mounted device.
In the vehicle control right switching process of the vehicle-mounted equipment, the general vehicle-mounted equipment can receive a switching command from a driver or ground equipment, and the vehicle control right is authorized to the general vehicle-mounted equipment of the switching command or the appointed special vehicle-mounted equipment according to the switching command, so that the operation of a train is monitored by the matched vehicle-mounted equipment on different lines, and the driving safety is ensured. Only one kind of vehicle-mounted equipment can have train monitoring rights at any time. For example, a general line supports a general vehicle-mounted device, a specific line supports a special vehicle-mounted device A, and when a train runs on the general line, the general vehicle-mounted device monitors the safe running of the train; when the train needs to leave the general line and enter the specific line, the general vehicle-mounted equipment switches the control right to the special vehicle-mounted equipment A according to the ground command or the driver command, and the special vehicle-mounted equipment A monitors the safe running of the train on the specific line.
In the vehicle control right switching process of the vehicle-mounted equipment, 8 working states including a non-power-on state, a configuration state, a data input state, a cold standby state, a hot standby state, a vehicle control state and a fault state are designed for the special vehicle-mounted equipment.
The special vehicle-mounted equipment is electrified and automatically enters an electrified state from an unpowered state;
in the power-on state, the special vehicle-mounted equipment and the general vehicle-mounted equipment are in communication connection; meanwhile, the special vehicle-mounted equipment sends a configuration state entering request to the general vehicle-mounted equipment, the general vehicle-mounted equipment sends a configuration state entering command to the special vehicle-mounted equipment, and the special vehicle-mounted equipment enters a configuration state;
in the configuration state, the general vehicle-mounted device transmits general train data, a train interface state, a brake interface state, speed and distance measurement performance parameters and brake performance parameters to the special vehicle-mounted device.
If the special vehicle-mounted equipment needs special train data, the special vehicle-mounted equipment sends a data input state entering request to the general vehicle-mounted equipment, the general vehicle-mounted equipment sends a data input state entering command to the special vehicle-mounted equipment, and the special vehicle-mounted equipment enters a data input state;
if the special vehicle-mounted equipment does not need special train data, the special vehicle-mounted equipment sends a cold standby state entering request to the general vehicle-mounted equipment, the general vehicle-mounted equipment sends a cold standby state entering command to the special vehicle-mounted equipment, and the special vehicle-mounted equipment enters a cold standby state.
The meaning of special train data means that the general train data does not include those train data that are required by the special on-board devices. For example, the CTCS-2 level train control system in china is a special train control system, and a driver is required to select carrier frequency, so that the vehicle-mounted device can correctly decode carrier frequency information on the ground track circuit. However, the general vehicle-mounted device does not use the track circuit information, and therefore, the track circuit interface is not needed, and a driver is not required to select carrier frequencies.
In the cold standby state, the special vehicle-mounted equipment cannot receive data sent by the ground through the special ground receiving and sending unit; in the cold standby state, if the special vehicle-mounted equipment receives a command for entering the vehicle control state from the general vehicle-mounted equipment, the special vehicle-mounted equipment enters the vehicle control state and monitors the running of the train; in the cold standby state, if the general vehicle-mounted equipment receives a switching command from the ground equipment or the driver, the switching command designates the special vehicle-mounted equipment to enter the hot standby state, and the general vehicle-mounted equipment sends a command for entering the hot standby state to the designated special vehicle-mounted equipment, so that the designated special vehicle-mounted equipment enters the hot standby state.
In the hot standby state, the special vehicle-mounted equipment can receive ground data and prepare data after entering the vehicle control state; if the special vehicle-mounted equipment receives a command for entering a vehicle control state from the general vehicle-mounted equipment, the special vehicle-mounted equipment enters the vehicle control state and monitors the running of the train; if a command to enter a cold standby state is received from the general vehicle-mounted device, the special vehicle-mounted device enters the cold standby state.
In the embodiment of the invention, in a data input state, the special vehicle-mounted equipment requests a driver to input special train data through a human-computer interface function, and after the special train data input is completed, the special vehicle-mounted equipment sends a cold standby state entering request to the general vehicle-mounted equipment, and the general vehicle-mounted equipment sends a cold standby state entering command to the special vehicle-mounted equipment, so that the special vehicle-mounted equipment enters the cold standby state.
In the power-on state, the configuration state, the data input state, the cold standby state, the hot standby state and the vehicle control state, if the special vehicle-mounted equipment detects that the special vehicle-mounted equipment fails, or the general vehicle-mounted equipment detects that the special vehicle-mounted equipment fails and sends a command for entering the failure state to the special vehicle-mounted equipment, the special vehicle-mounted equipment enters the failure state; the general vehicle-mounted equipment prohibits switching the control right to the special vehicle-mounted equipment with faults, and driving safety is ensured.
And in the power-on state, the configuration state, the data input state, the cold standby state, the hot standby state, the vehicle control state and the fault state, the special vehicle-mounted equipment is powered off, and enters the power-off state.
The train control vehicle-mounted equipment system compatible with various train control systems designed according to the invention further introduces a train control right switching process between the special vehicle-mounted equipment and the special vehicle-mounted equipment.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for switching the control right of the special vehicle-mounted device a to the special vehicle-mounted device B in the embodiment of the invention. The process is as follows:

The special vehicle-mounted device B in the hot standby state provides information such as the allowable speed of the special vehicle-mounted device B, a device switching confirmation area and the like for the general vehicle-mounted device, the general vehicle-mounted device forwards the information to the special vehicle-mounted device A in the vehicle control state, the special vehicle-mounted device A brings the allowable speed of the special vehicle-mounted device B into a speed monitoring curve (taking the minimum value of the allowable speed of the special vehicle-mounted device B and the allowable speed of the special vehicle-mounted device A as the allowable speed of a device switching execution point), and the train is ensured to pass through the device switching execution point at a smooth speed. After the train passes through the equipment switching execution point, the general vehicle-mounted equipment controls the special vehicle-mounted equipment A in the car control state to enter a cold standby state, and the special vehicle-mounted equipment A sends cold standby state information to the general vehicle-mounted equipment; the general vehicle-mounted equipment controls the special vehicle-mounted equipment B to enter a vehicle control state from the hot standby state, the special vehicle-mounted equipment B starts to monitor the train operation, the special vehicle-mounted equipment B enters the vehicle control state, the general vehicle-mounted equipment stops temporarily monitoring the train operation, and the vehicle control right is completely given to the special vehicle-mounted equipment B, so that the equipment is successfully switched.

After receiving the device switching confirmation command, the driver sends a service braking command to the train by the general vehicle-mounted device after overtime in a certain time if the driver does not confirm the device switching until the driver confirms the device switching.
In the process that the special vehicle-mounted equipment A switches the train control right to the special vehicle-mounted equipment B, after the train passes through the equipment switching execution point, the general vehicle-mounted equipment commands the special vehicle-mounted equipment A to enter a cold standby state from the train control state, and the general vehicle-mounted equipment temporarily monitors the train operation until the special vehicle-mounted equipment B enters the train control state.
Meanwhile, after the train passes through the equipment switching execution point, the general vehicle-mounted equipment controls the special vehicle-mounted equipment A to enter a cold standby state, and the special vehicle-mounted equipment A sends cold standby state information to the general vehicle-mounted equipment; if the general vehicle-mounted equipment does not receive the information that the special vehicle-mounted equipment A enters the cold standby state within a certain time, the general vehicle-mounted equipment controls the special vehicle-mounted equipment A to enter the fault state.
In the process that the special vehicle-mounted equipment A switches the vehicle control right to the special vehicle-mounted equipment B, the general vehicle-mounted equipment controls the special vehicle-mounted equipment B to enter a vehicle control state, and the special vehicle-mounted equipment B sends the vehicle control state information to the general vehicle-mounted equipment; if the general vehicle-mounted equipment does not receive the information that the special vehicle-mounted equipment B enters the vehicle control state within a certain time, the general vehicle-mounted equipment controls the special vehicle-mounted equipment B to enter the fault state, and the equipment switching fails.
