In the embodiment of the invention, the special vehicle-mounted equipment only comprises a train safety monitoring function and a function of interacting with ground equipment.
Illustratively, the special in-vehicle devices are denoted as a special in-vehicle device a and a special in-vehicle device 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 onboard equipment system compatible with various train control systems. The general vehicle-mounted equipment comprises 10 modules, namely a train monitoring function, a wireless transmission function, a transponder transmission function, a speed 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 general vehicle-mounted equipment and ground equipment and between 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 for the general vehicle-mounted equipment and the special vehicle-mounted equipment. The speed and distance measuring functional module is used for calculating the position, the speed and the direction of the train and providing the position, the speed and the direction for general vehicle-mounted equipment and 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 data recording function module is used for recording the operation data of the general vehicle-mounted equipment and the special vehicle-mounted equipment. The train interface function module is used for collecting train interface input information and providing the train interface input information for general vehicle-mounted equipment and special vehicle-mounted equipment. The braking interface functional module is used for outputting braking commands to the train by 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 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 the 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 the special vehicle-mounted equipment can be controlled through the special vehicle-mounted equipment control function module, and the control right between the general vehicle-mounted equipment and the special vehicle-mounted equipment can be switched. 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 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 bus (or other buses, such as an MVB bus), and shares information acquired by 8 functional modules of a wireless transmission function, a transponder transmission function, a speed 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 the 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 exchange information with the ground equipment through the special ground information transceiving unit A and the special ground information transceiving unit B respectively, and the special vehicle-mounted equipment A and the special vehicle-mounted equipment B are used for monitoring the safe operation of the train on a specific line provided with corresponding ground equipment. The special ground information transceiver unit is an information receiving unit which is installed on the special vehicle-mounted device and can receive the information of the ground device on the specific line, and the special ground information transceiver 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 collected, one type of special ground information transceiver unit is used; if there are two different types of ground information to be collected, two different types of special ground information transceiver units need to be used.
The specific lines refer to lines supporting different special train control systems, and corresponding special ground equipment is installed on the lines. For example, if there is a line supporting a special train control system X, then special ground equipment L is installed on the ground. When the train needs to enter the line to run, the train control right of the vehicle-mounted equipment needs to be converted into the special vehicle-mounted equipment A through a ground command 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 the sharing functions of the general vehicle-mounted equipment.
After a train control vehicle-mounted equipment system compatible with various train control systems is powered on, the special vehicle-mounted equipment requests to establish communication connection with the general vehicle-mounted equipment, and the general vehicle-mounted equipment receives the request and checks the system version of the special vehicle-mounted equipment. If the versions of the special vehicle-mounted equipment and the universal vehicle-mounted equipment are compatible, the universal vehicle-mounted equipment and the special vehicle-mounted equipment are successfully established in communication connection; and if the versions are not compatible, the general vehicle-mounted equipment refuses to establish communication connection with the special vehicle-mounted equipment.
In the process of controlling the right of train switching by the vehicle-mounted equipment, the general vehicle-mounted equipment can receive a switching command from a driver or ground equipment, and authorizes the right of train control to the general vehicle-mounted equipment or the appointed special vehicle-mounted equipment of the switching command according to the switching command, so that the running of the train is monitored by the matched vehicle-mounted equipment on different lines, and the running safety is ensured. Only one vehicle-mounted device can own the train monitoring right at any time. For example, a general line supports general vehicle-mounted equipment, a specific line supports special vehicle-mounted equipment A, and when a train runs on the general line, the general vehicle-mounted equipment monitors the safe running of the train; when the train needs to leave a general line and enter a specific line, the general vehicle-mounted equipment switches the train control right to the special vehicle-mounted equipment A according to a ground command or a driver command, and the special vehicle-mounted equipment A monitors the safe running of the train on the specific line.
In the process of switching the vehicle control right of the vehicle-mounted equipment, 8 working states including an unpowered state, a powered 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.
Powering on the special vehicle-mounted equipment, and automatically entering a powered-on state from an unpowered state;
in a power-on state, the special vehicle-mounted equipment and the general vehicle-mounted equipment establish communication connection; meanwhile, the special vehicle-mounted equipment sends a request for entering a configuration state to the general vehicle-mounted equipment, the general vehicle-mounted equipment sends a command for entering the configuration state to the special vehicle-mounted equipment, and the special vehicle-mounted equipment enters the configuration state;
and in the configuration state, the general vehicle-mounted equipment sends general train data, a train interface state, a brake interface state, speed and distance measuring performance parameters and brake performance parameters to the special vehicle-mounted equipment.
If the special vehicle-mounted equipment needs special train data, the special vehicle-mounted equipment sends a request for entering a data input state to the general vehicle-mounted equipment, the general vehicle-mounted equipment sends a command for entering the data input state to the special vehicle-mounted equipment, and the special vehicle-mounted equipment enters the data input state;
if the special vehicle-mounted equipment does not need special train data, the special vehicle-mounted equipment sends a request for entering the cold standby state to the general vehicle-mounted equipment, the general vehicle-mounted equipment sends a command for entering the cold standby state to the special vehicle-mounted equipment, and the special vehicle-mounted equipment enters the cold standby state.
The meaning of the special train data is that the special train data refers to those train data which are not included in the general train data but required by the special on-board device. For example, a Chinese CTCS-2 level train control system is a special train control system, and a driver needs to select a carrier frequency, so that the vehicle-mounted equipment can correctly decode the carrier frequency information on the ground track circuit. However, the track circuit information is not suitable for the general vehicle-mounted equipment, a track circuit interface is not available, and a driver does not need to select carrier frequency.
In a cold standby state, the special vehicle-mounted equipment cannot receive data transmitted on the ground through the special ground transceiving unit; in the cold standby state, if the special vehicle-mounted equipment receives a command of 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; in the cold standby state, if the general vehicle-mounted equipment receives a switching command from the ground equipment or a driver, the switching command designates the special vehicle-mounted equipment to enter the hot standby state, the general vehicle-mounted equipment sends a command for entering the hot standby state to the designated special vehicle-mounted equipment, and 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 the data after entering the vehicle control state; if the special vehicle-mounted equipment receives a command of 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; and if the command of entering the cold standby state is received from the general vehicle-mounted equipment, the special vehicle-mounted equipment 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 man-machine interface function, after the special train data is input, the special vehicle-mounted equipment sends a request of entering a cold standby state to the general vehicle-mounted equipment, the general vehicle-mounted equipment sends a command of entering the cold standby state to the special vehicle-mounted equipment, and the special vehicle-mounted equipment enters the cold standby state.
Under 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 has a fault, or the general vehicle-mounted equipment detects that the special vehicle-mounted equipment has a fault and sends a fault state entering command to the special vehicle-mounted equipment, the special vehicle-mounted equipment enters the fault state; the general vehicle-mounted equipment prohibits switching the vehicle control right to the special vehicle-mounted equipment with faults, and driving safety is guaranteed.
And under 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 unpowered state.
