[0024] In order to enable those skilled in the art to better understand the technical solutions of the present application, the communication method of the rail transit dispatching system and the related device thereof provided by the present application are further described in detail below in combination with the drawings and specific embodiments.

[0025] In an embodiment, as shown in Figure 1 the rail transit dispatching system 10 comprises a vehicle-mounted station 13, a wireless forwarding device 11 and a dispatching station 12.

[0026] One or more wireless forwarding devices 11 are arranged along the track of the vehicle, so that the vehicle can communicate with the dispatching station 12 through the wireless forwarding device 11 when it is at a corresponding position on the track.

[0027] The wireless forwarding device 11 is used to broadcast position information. Moreover, the track of the vehicle can be within the communication coverage of the wireless forwarding device 11, so that the vehicle can receive the position information broadcast by the wireless forwarding device 11 and communicate with the dispatching station 12 through the wireless forwarding device 11 when it is at any position on the track.

[0028] The wireless forwarding device 11 can be composed of a vehicle station terminal and a control circuit. The wireless forwarding device 11 can be connected to the vehicle-mounted station 13 in a wireless manner. Alternatively, the wireless forwarding device 11 can communicate with the vehicle-mounted station 13 in a direct mode operation (DMO).

[0029] In addition, the communication coverage of two adjacent wireless forwarding devices 11 can overlap or not overlap.

[0030] In addition, the wireless forwarding device 11 can be configured with at least two channels, one of which is used to broadcast the current position and send / receive short messages, and the other of which is used for voice communication, so as to ensure that the short messages and the call do not interfere with each other.

[0031] The vehicle-mounted station 13 is arranged on the vehicle. The worker on the vehicle can communicate with the dispatching station 12 through the vehicle-mounted station 13. The vehicle-mounted station 13 is used to obtain position information, determine the position of the vehicle-mounted station 13 according to the position information, and send the position information of the vehicle-mounted station 13 to the dispatching station 12 through the wireless forwarding device 11. The vehicle can be a train.

[0032] The dispatch station 12 is arranged in the dispatch hall of the control center. The dispatch station 12 is communicatively connected with each wireless forwarding device 11 through a wired network. The dispatch station 12 can be used to acquire and display the position information of the vehicle-mounted station 13, and communicate with the vehicle-mounted station 13 through the wireless forwarding device 11.

[0033] The dispatch station 12 can dynamically and real-timely display the positions of all vehicles. If a vehicle is to be called, a corresponding group can be selected to initiate a call. The dispatch station 12 initiates a call to the vehicle-mounted station 13 through the private protocol to control the wireless forwarding device 11 in the area where the vehicle is located. After the call is established, the wireless forwarding device 11 forwards the voice of the dispatcher to the vehicle-mounted station 13, and receives the voice of the vehicle-mounted station 13 to forward to the dispatch station 12, thereby realizing the function of calling the vehicle.

[0034] Optionally, the vehicle-mounted station 13 and the wireless forwarding device 11 can both work in the DMO mode, i.e., the vehicle-mounted station 13 communicates with the wireless forwarding device 11 through the DMO mode. In this way, the track dispatching system 10 can not need a base station as an information transfer station, thereby reducing the construction difficulty and cost.

[0035] In addition, the track dispatching system 10 can further include a handheld station 14 and a station duty room vehicle station 15. The handheld station 14 and the station duty room vehicle station 15 can be communicatively connected with the dispatch station 12 through the wireless forwarding device 11. In addition, the handheld station 14 / station duty room vehicle station 15 in the same station or within the communication coverage range of the same wireless forwarding device 11 can directly communicate with the vehicle-mounted station 13.

[0036] For details, please refer to Figure 2 , Figure 2 This is an interactive schematic diagram of the first embodiment of the communication method of the track dispatching system according to the present application based on the above. The communication method of the track dispatching system according to the present embodiment includes the following steps.

[0037] 101: The wireless forwarding device broadcasts device position information.

[0038] The wireless forwarding device broadcasts the device position information, so that the vehicle-mounted station on the vehicle running or staying on the track can determine the position where the vehicle-mounted station is located based on the device position information.

[0039] The wireless forwarding device generally broadcasts the device position information every 5s, 10s, etc., so that the vehicle-mounted station can timely determine the position where the vehicle-mounted station is located.

[0040] The channel and / or time slot resource used by the wireless forwarding device to broadcast the device location information can be consistent with the channel and / or time slot resource used by the vehicle-mounted station in general, so that the vehicle-mounted station in the broadcasting range of the wireless forwarding device and not having established a communication connection with the wireless forwarding device can normally receive the device location information after the wireless forwarding device broadcasts the device location information, so that the vehicle-mounted station can establish a communication connection with the wireless forwarding device based on the device location information.

[0041] The content of the device location information can include the current area of the wireless forwarding device. For example, the content of the device location information can include "XX station XX area".

[0042] In addition, in an implementation, the wireless forwarding device can be loaded with a positioning module for obtaining the location information of the wireless forwarding device and sending the location information to the control circuit, so that the control circuit integrates the location information into the device location information and broadcasts the device location information.

[0043] In another implementation, the wireless forwarding device can be used to receive the location information input by the staff and / or the device location information and broadcast the device location information.

[0044] 102: The vehicle-mounted station determines the location of the vehicle-mounted station according to the device location information.

[0045] After receiving the device location information, the vehicle-mounted station can parse the device location information and determine the location of the vehicle-mounted station.

[0046] 103: The vehicle-mounted station sends the vehicle-mounted station location information to the wireless forwarding device.

[0047] The vehicle-mounted station can arrange the location of the vehicle-mounted station into the vehicle-mounted station location information and send the vehicle-mounted station location information to the wireless forwarding device.

[0048] The vehicle-mounted station can send the vehicle-mounted station location information to the wireless forwarding device. The channel and / or time slot resource used by the vehicle-mounted station to send the vehicle-mounted station location information can be inconsistent with the channel and / or time slot resource of the wireless forwarding device, so as to prevent the wireless forwarding device from colliding when transmitting and receiving information, and avoid the wireless forwarding device from failing to normally receive the vehicle-mounted station location information sent by the vehicle-mounted station due to packet loss.

[0049] 104: The wireless forwarding device forwards the vehicle-mounted station location information to the dispatching station.

[0050] After receiving the vehicle-mounted station location information sent by the vehicle-mounted station, the wireless forwarding device can forward the vehicle-mounted station location information to the dispatching station, so that the dispatching station knows the location of the vehicle-mounted station and can determine the wireless forwarding device as an information transfer station.

[0051] 105: The dispatching station displays the location of the vehicle-mounted station.

[0052] The dispatching station can display the position of the vehicle station after receiving the position information of the vehicle station, so that the dispatcher can select the staff of the vehicle corresponding to the vehicle station to communicate according to the data displayed on the interface of the dispatching station.

[0053] 106: The dispatching station communicates with the vehicle station through the wireless forwarding device.

[0054] The dispatching station can communicate with the vehicle station through the wireless forwarding device.

[0055] The dispatching station can be connected with each wireless forwarding device through a wired network. The wireless forwarding device can be wirelessly connected with the vehicle station.

[0056] The dispatching station can control the wireless forwarding device to send voice or short message to the vehicle station through a private protocol, or the wireless forwarding device uploads the short message or voice initiated by the vehicle station to the dispatching station, so as to realize voice communication and short message transmission between the dispatching station and the vehicle station. The wireless forwarding device plays a role of communication data relay in the rail transit dispatching system.

[0057] In addition, in the process of voice communication between the dispatching station and the vehicle station, the wireless forwarding device needs to convert the network voice data of the dispatching station into analog voice and send it to the vehicle station, and at the same time, convert the analog voice of the vehicle station into network voice data and send it to the dispatching station.

[0058] In an application scenario, the process of the dispatching station initiating voice communication with the vehicle station can include: the dispatching station sends voice data to the wireless forwarding device, and the wireless forwarding device sends the voice data to the corresponding vehicle station according to the call number.

[0059] In another application scenario, the process of the dispatching station initiating short message communication with the vehicle station can include: the dispatching station sends short message data to the wireless forwarding device, and the wireless forwarding device sends the short message data to the corresponding vehicle station according to the call number. Specifically, the dispatcher sends a short message to the vehicle station by operating the interface of the dispatching station, and the short message is transmitted to each wireless forwarding device along the line through a wired network. The wireless forwarding device analyzes the short message and then forwards the short message through a wireless network. Since each vehicle will establish a communication connection with a wireless forwarding device when running on the track, the vehicle station on the vehicle will always receive the short message.

[0060] In another application scenario, the process that the vehicle station initiates the short message communication with the dispatch station can include: the vehicle station sends the short message data to the wireless forwarding device, and the wireless forwarding device sends the short message data to the dispatch station. The short message data sent by the vehicle station can include the short message data of the call request. Specifically, when the vehicle station sends the short message, the wireless forwarding device in the coverage range receives the short message. After the wireless forwarding device analyzes the short message, the wireless forwarding device forwards the short message to the dispatch station through the wired network. After the dispatch station analyzes, the dispatch station presents to the dispatcher, and the short message transmission from the vehicle station to the dispatch station is realized.

[0061] Of course, the specific communication process can not be limited to this.

[0062] In this embodiment, the wireless forwarding device broadcasts the device location information as a communication relay station. The vehicle station can realize the communication between the vehicle station and the dispatch station and determine the location of the vehicle station through the wireless forwarding device. Without setting other location determination devices and communication relay devices, the construction difficulty and construction cost can be reduced.

[0063] For details, please refer to Figure 3 , Figure 3 This is an interactive schematic diagram of the second embodiment of the method for communicating based on the above rail transit dispatching system. The communication method of the rail transit dispatching system in this embodiment includes the following steps.

[0064] 201: The wireless forwarding device broadcasts the device location information.

[0065] 202: The vehicle station determines the location of the vehicle station according to the device location information.

[0066] 203: The vehicle station switches to the DMO group of the wireless forwarding device based on the location of the vehicle station.

[0067] Among them, the voice communication channels of different wireless forwarding devices are configured with different DMO groups, so that the vehicle station only communicates with the dispatch station through one wireless forwarding device, avoiding the voice data sent by the vehicle station located in the overlapping area of the communication coverage of the two adjacent wireless forwarding devices from being received by the two wireless forwarding devices, and preventing the waste of communication resources.

[0068] After the vehicle station receives the device location information broadcast by the wireless forwarding device, the vehicle station can confirm the DMO group of the voice communication channel of the wireless forwarding device that broadcasts the device location information based on the device location information, and then switch the DMO group of its voice communication channel to the DMO group of the wireless forwarding device, so as to communicate with the control station through the wireless forwarding device. In other implementations, the vehicle station can first confirm the location of the vehicle station based on the device location information, and then confirm the DMO group of the voice communication channel of the wireless forwarding device required to establish a communication connection with the dispatch station based on the location of the vehicle station.

[0069] Optionally, the correspondence between the DMO group of the voice communication channel and the device position information or the on-board station position information can be stored in the on-board station, so that the on-board station can determine the DMO group of the voice communication channel after the device position information or the on-board station position information is confirmed.

[0070] 204: The on-board station sends the on-board station position information to the wireless forwarding device.

[0071] 205: The wireless forwarding device forwards the on-board station position information to the dispatch station.

[0072] 206: The dispatch station displays the position of the on-board station.

[0073] 207: The dispatch station communicates with the on-board station through the wireless forwarding device.

[0074] 208: The handheld station / station duty room on-board station communicates with the dispatch station through the wireless forwarding device.

[0075] The handheld station / station duty room on-board station can communicate with the dispatch station through the wireless forwarding device in voice and short message.

[0076] In an application scenario, the process of the dispatch station initiating voice communication with the handheld station / station duty room on-board station can include: the dispatch station sends voice data to the wireless forwarding device, and the wireless forwarding device sends the voice data to the corresponding handheld station / station duty room on-board station according to the call number.

[0077] It can be understood that the execution sequence of step 208 is not limited to this, and can be before or after step 203 in the embodiment.

[0078] 209: The handheld station / station duty room on-board station communicates with the on-board station.

[0079] The handheld station / station duty room on-board station and the on-board station under the communication coverage of the same wireless forwarding device can directly communicate when there is a communication demand.

[0080] Or the handheld station / station duty room on-board station and the on-board station located in the same station have a communication demand, and since they are in the same station, they can directly communicate.

[0081] The execution sequence of step 209 is not limited to this, and can be after step 203 in the embodiment.

[0082] In the embodiment, the device position information is broadcasted by the wireless forwarding device as a communication relay station, so that the on-board station can realize communication with the dispatch station and determine the position of the on-board station through the wireless forwarding device, without the need to set other position determining devices and communication relay devices, which can reduce the construction difficulty and construction cost.

[0087] The wireless forwarding device communicates with the vehicle-mounted station through the DMO mode.

[0088] In addition, different wireless forwarding devices are configured with different DMO groups.

[0089] In addition, the wireless forwarding device is configured with at least two channels, one of which is used for broadcasting location information and short message communication, and the other is used for voice communication, so that the call and the short message do not interfere with each other.
