Detailed Description
Currently, a maglev transportation operation control system generally comprises a maglev train positioning system (which may also be referred to as a positioning device in the present embodiment), a train-ground wireless communication system and a maglev traction control system. The train-ground wireless communication system is an important component of a magnetic suspension traffic operation control system.
The train-ground wireless communication system establishes a spatial wireless communication link with a vehicle-mounted terminal on a train by utilizing a ground base station erected beside a track, provides a real-time, high-speed and reliable bidirectional wireless data transmission channel between a maglev train and the ground, and meets the data transmission requirements of maglev traffic system operation control, traction control, operation voice communication, diagnosis information, passenger information and the like.
For example, the train-ground wireless communication system transmits the positioning information acquired by the maglev train positioning system to the traction motor control unit of the maglev traction control system for controlling the traction motor. The magnetic suspension traction control system obtains real-time positioning information of the train and controls the traction force for driving the magnetic suspension train to run in real time according to the real-time positioning information and the line parameters of the train. The magnetic suspension traction control system requires that the transmission delay of train positioning data is not more than 5 milliseconds so as to meet the traction control requirement of the magnetic suspension train. This requires a high degree of redundancy in the communication between the magnetic levitation train positioning system and the train-ground wireless communication system in order to ensure the transmission reliability of the train positioning information.
In general, after the maglev train acquires the positioning information through the maglev train positioning system, the maglev train can send the acquired positioning information to the ground base station through the wireless communication network.
The speed of the maglev train is fast, so that a wireless communication network between the maglev train and the ground base station is unstable, and the situation that the positioning information is not transmitted to the ground base station when the maglev train transmits the positioning information to the ground base station is easily caused.
Based on this, the present embodiment provides a train operation control system, a train operation control method, and a train operation control device, where each of at least two vehicle-mounted radio control units in the train operation control system is connected to each other, so that positioning information interaction can be performed between each of the vehicle-mounted radio control units, positioning information acquired by all positioning devices is acquired, and the acquired positioning information acquired by all the positioning devices is transmitted to a ground traction control device, and after each of the vehicle-mounted radio control units performs positioning information interaction with other vehicle-mounted radio control units, positioning information acquired by all the vehicle-mounted radio control units in the train operation control system can be transmitted to the ground traction control device, thereby greatly increasing redundancy of positioning information transmission.
Example 1
This embodiment proposes a train operation control system, includes: at least two on-board radio control units, a positioning device, and a ground traction control device.
The vehicle-mounted radio control units in the at least two vehicle-mounted radio control units are mutually connected, and are respectively connected with ground traction control equipment and different positioning equipment.
The vehicle-mounted radio control unit is used for acquiring the positioning information acquired by the connected positioning equipment, sending the acquired positioning information to other vehicle-mounted radio control units connected with the vehicle-mounted radio control unit, receiving the positioning information sent by the other vehicle-mounted radio control units, and sending the acquired positioning information and the received positioning information to the ground traction control equipment.
The vehicle-mounted radio control unit is also used for collecting and utilizing information, collecting and decomposing the information, encoding and decoding information sources, transmitting an information safety transmission mechanism and the like; the system can collect train positioning information and pack and send the train positioning information to a subarea radio control unit on the ground. The in-vehicle radio control unit is a computer device storing a computer program.
And the positioning equipment is used for acquiring the positioning information of the magnetic-levitation train.
In order to further improve the redundancy of the positioning information transmission, the train operation control system provided in this embodiment may further include: at least two redundant vehicular radio control units.
Each redundant vehicle-mounted radio control unit of the at least two redundant vehicle-mounted radio control units is connected with each other, each redundant vehicle-mounted radio control unit is respectively connected with a ground traction control device and a different vehicle-mounted radio control unit, and the redundant vehicle-mounted radio control units are also connected with positioning devices connected with the connected vehicle-mounted radio control units;
the redundant vehicle-mounted radio control unit is used for acquiring the positioning information acquired by the connected positioning equipment, sending the acquired positioning information to the vehicle-mounted radio control unit and other redundant vehicle-mounted radio control units connected with the redundant vehicle-mounted radio control unit, receiving the positioning information sent by the vehicle-mounted radio control unit and other redundant vehicle-mounted radio control units connected with the redundant vehicle-mounted radio control unit, and sending the acquired positioning information and the received positioning information to the ground traction control equipment.
It can be seen from the above that, each positioning device is connected with one vehicle-mounted radio control unit and one redundant vehicle-mounted radio control unit, so that each positioning device can send positioning information to the connected vehicle-mounted radio control unit and the redundant vehicle-mounted radio control unit, so that in the train operation control system, one vehicle-mounted radio control unit and one redundant vehicle-mounted radio control unit can obtain the same positioning information, even if the positioning information obtained by the vehicle-mounted radio control unit or the redundant vehicle-mounted radio control unit has a problem in the transmission process to the ground traction control device, the positioning information can be transmitted to the ground traction control device, and the redundancy of the positioning information sending is increased.
Since each vehicle-mounted radio control unit and the connected redundant vehicle-mounted radio control unit transmit positioning information in different network frequency bands, in order to enable each vehicle-mounted radio control unit and the connected redundant vehicle-mounted radio control unit to smoothly transmit the positioning information to the ground traction control device, the train operation control system provided by the embodiment further comprises: a plurality of sectorized radio control units of sectorized operating respectively in different network frequency bands.
And each subarea radio control unit in the plurality of subarea radio control units is respectively connected with the vehicle-mounted radio control unit and the redundant vehicle-mounted radio control unit with the same network frequency band as the ground traction control equipment.
And the subarea radio control unit is used for transmitting the positioning information sent by the connected vehicle-mounted radio control unit and the redundant vehicle-mounted radio control unit to the ground traction control equipment.
Here, the term "location information exchange" refers to a vehicle-mounted radio control unit or a redundant vehicle-mounted radio control unit, which transmits the acquired location information to the vehicle-mounted radio control unit and the redundant vehicle-mounted radio control unit connected to the vehicle-mounted radio control unit itself or the redundant vehicle-mounted radio control unit itself, and receives the location information transmitted from the vehicle-mounted radio control unit and the redundant vehicle-mounted radio control unit connected to the vehicle-mounted radio control unit itself or the redundant vehicle-mounted radio control unit itself.
And all the positioning information comprises the positioning information acquired by the vehicle-mounted radio control unit or the redundant vehicle-mounted radio control unit from the positioning equipment and the positioning information obtained by interacting with other equipment.
The operation principle of the train operation control system is further described by the following example.
Referring to fig. 1, a schematic structural diagram of an implementation manner of the train operation control system includes: a plurality of positioning devices 1, a vehicle-ground communication device 2 and a ground traction control device 3.
The vehicle-ground communication device 2 includes: a plurality of on-board radio control units 21 and a plurality of sectorized radio control units 22, wherein each on-board radio control unit 21 of the plurality of on-board radio control units 21 is connected with each of the plurality of positioning devices 1, and the plurality of on-board radio control units 21 are connected with the ground traction control device 3 through the plurality of sectorized radio control units 22.
Each vehicle-mounted radio control unit 21 in the vehicle-ground communication device 2 respectively acquires the positioning information acquired by the positioning device 1 connected with the vehicle-mounted radio control unit 21, acquires the positioning information acquired by all other positioning devices 1 through the interaction of the positioning information of other vehicle-mounted radio control units 21 connected with the vehicle-mounted radio control unit 21, and transmits the acquired positioning data packet including all the positioning information to the ground traction control device 3 through the subarea radio control unit 22.
Specifically, the number of the plurality of positioning devices is at least two. It should be noted that, of course, fig. 1 is a diagram schematically illustrating an example in which the number of positioning devices is four, but the specific number of positioning devices 1, that is, the number of the plurality of in-vehicle radio control units 21, is not specifically limited in this embodiment.
Specifically, the in-vehicle radio control unit may be an in-vehicle terminal.
Specifically, the plurality of vehicle-mounted radio control units 21 have a connection relationship therebetween to implement location information interaction, but it should be noted herein that the connection manner between the plurality of vehicle-mounted radio control units 21 may be determined according to actual situations, as long as it is ensured that each vehicle-mounted radio control unit 21 can acquire location information collected by all other location devices through information interaction with other vehicle-mounted radio control units. This is exemplified below.
For example, it is assumed that the plurality of in-vehicle radio control units include an in-vehicle radio control unit a, an in-vehicle radio control unit B, and an in-vehicle radio control unit C. One connection mode can be that the vehicle-mounted radio control unit A is respectively connected with the vehicle-mounted radio control unit B and the vehicle-mounted radio control unit C, at the moment, the vehicle-mounted radio control unit A respectively carries out information interaction with the vehicle-mounted radio control unit B and the vehicle-mounted radio control unit C, namely, the vehicle-mounted radio control unit A can acquire the positioning information acquired by the vehicle-mounted radio control unit B and the vehicle-mounted radio control unit C, at the moment, the vehicle-mounted radio control unit B can acquire all the positioning information through the interaction with the vehicle-mounted radio control unit A, and similarly, the vehicle-mounted radio control unit C can acquire all the positioning information through the interaction with the vehicle-mounted radio control unit A, so that each vehicle-mounted radio control unit can acquire the positioning information acquired by the other two vehicle-mounted radio control units, further obtaining all positioning information; in addition, the two connection modes are that the vehicle-mounted radio control unit a is connected with the vehicle-mounted radio control unit B, the vehicle-mounted radio control unit B is connected with the vehicle-mounted radio control unit C, at this time, the vehicle-mounted radio control unit a performs information interaction with the vehicle-mounted radio control unit B, the vehicle-mounted radio control unit B performs information interaction with the vehicle-mounted radio control unit C, that is, the vehicle-mounted radio control unit B can acquire the positioning information acquired by the vehicle-mounted radio control unit a and the vehicle-mounted radio control unit C, at this time, the vehicle-mounted radio control unit a can acquire all the positioning information by interacting with the vehicle-mounted radio control unit B, and similarly, the vehicle-mounted radio control unit C can acquire all the positioning information by interacting with the vehicle-mounted radio control unit B. Therefore, through information interaction among the plurality of vehicle-mounted radio control units, each vehicle-mounted radio control unit can acquire the positioning information acquired by all the positioning devices, and the integrity of the positioning information transmitted by the vehicle-mounted radio control units is ensured.
In addition, specifically, the communication mode between the vehicle-mounted radio control unit 21 and the sectorized radio control unit 22 is a wireless communication mode, that is, a wireless connection is made between the vehicle-mounted radio control unit 21 and the sectorized radio control unit 22. At this time, each of the on-vehicle radio control units 21 may transmit the acquired positioning data packet including all the positioning information to the ground traction control apparatus 3 through the sectorized radio control unit 22 with which wireless communication is performed.
