All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The embodiment of the application discloses a method and a system for updating a vehicle-mounted signal system of a tramcar based on UWB, and the method and the system are described in detail below with reference to the attached drawings.
Referring to fig. 1, fig. 1 is a schematic flowchart of a first embodiment of an update method for a vehicle-mounted signal system of a tram based on UWB according to an embodiment of the present application. In a first embodiment, a plurality of UWB (ultra wide band) wayside devices are arranged at intervals along the length direction of a tram track beside the track, and a first UWB antenna is arranged on each UWB wayside device. As shown in fig. 1, the update method of the vehicle-mounted signal system of the UWB-based tram may include the steps of:
101. the dispatching command center monitors whether a vehicle-ground communication device included in a vehicle-mounted signal system of a first tramcar running on the tramcar track breaks down or not, if so, detects whether a second tramcar running in front of the first tramcar exists on the tramcar track or not and whether a vehicle-ground communication device included in the vehicle-mounted signal system of the second tramcar is normal or not, and if so, sends information to be updated corresponding to the vehicle-ground communication device included in the vehicle-mounted signal system of the first tramcar to the vehicle-ground communication device included in the vehicle-mounted signal system of the second tramcar.
For example, the dispatching command center may monitor whether a heartbeat connection between a vehicle-ground communication device included in a vehicle-mounted signal system of a first tramcar running on the tramcar track and the dispatching command center is interrupted, and if the heartbeat connection is interrupted, it may be determined that the vehicle-ground communication device included in the vehicle-mounted signal system of the first tramcar is faulty; on the contrary, if the interruption is not performed, it can be determined that the vehicle-ground communication device included in the vehicle-mounted signal system of the first tramcar is normal (i.e. has no fault).
For example, the information to be updated corresponding to the vehicle-mounted signal system of the first tram may include an instruction to be updated of a turnout controller in the vehicle-mounted signal system of the first tram, a version to be updated of a vehicle-mounted cab man-machine interface (MMI), and the like.
102. The second tramcar acquires information to be updated corresponding to the vehicle-mounted signal system of the first tramcar from vehicle-ground communication equipment included in the vehicle-mounted signal system of the second tramcar, and when the distance between a second UWB antenna arranged at the front end of the train head of the second tramcar and a first UWB antenna of a first target UWB roadside device to be driven is calculated to be smaller than or equal to a preset distance threshold value during the track running of the tramcar, the information to be updated corresponding to the UWB of the vehicle-mounted signal system of the first tramcar is sent to the first UWB antenna of the first target UWB roadside device through the second UWB antenna, so that the first target UWB roadside device stores the information to be updated corresponding to the vehicle-mounted signal system of the first tramcar; the first target UWB wayside device belongs to a UWB wayside device of the plurality of UWB wayside devices that is closest to the second tram that the second tram has not yet driven.
In the embodiment of the present application, the second tram can utilize UWB (ultra wide band) technology to calculate the distance between the second UWB antenna arranged at the front end of the head of the second tram and the first UWB antenna of the first target UWB wayside device to be driven on the way of tram rail running, and when determining that the distance is less than or equal to a preset distance threshold value, the second UWB antenna sends the information to be updated corresponding to the vehicle-mounted signal system of the first tram to the first UWB antenna of the first target UWB wayside device. The UWB technology mainly has 3 major characteristics, namely, the positioning speed is very high, and the positioning precision is high; secondly, the distance between the two UWB antennas can be accurately calculated; and thirdly, the UWB has the characteristic of high bandwidth and can support the rapid transmission of signals such as data, audio and video and the like.
The preset distance threshold may be set according to actual needs, and the embodiment of the present application is not particularly limited.
103. When the distance between a third UWB antenna arranged at the front end of the train head of the first tramcar and a first UWB antenna of the first target UWB roadside device to be driven to is calculated by the first tramcar on the way of the tramcar track running and is smaller than or equal to the preset distance threshold, a request for acquiring information to be updated is sent to the first UWB antenna of the first target UWB roadside device through the third UWB antenna.
104. The first tramcar acquires the information to be updated corresponding to the vehicle-mounted signal system of the first tramcar, which is sent by the first target UWB roadside device through the first UWB antenna of the first target UWB device, through the third UWB antenna.
105. And the first tramcar correspondingly updates the vehicle-mounted signal system of the first tramcar according to the information to be updated corresponding to the vehicle-mounted signal system of the first tramcar.
The first tram does not affect the normal running of the first tram on the tram track when the first tram correspondingly updates the vehicle-mounted signal system of the first tram according to the information to be updated corresponding to the vehicle-mounted signal system of the first tram.
For example, when the information to be updated is an update instruction of a switch controller in the on-board signal system of the first tramcar, the first tramcar may perform instruction update on the switch controller in the on-board signal system of the first tramcar according to the update instruction of the switch controller; the first tram may update the command of the switch controller in the on-board signal system of the first tram according to the update command of the switch controller before the first tram performs switch control, and this process does not affect the normal running of the first tram on the tram track.
It can be seen that, by implementing the method described in fig. 1, even if the vehicle-ground communication device in the on-board signal system of the first tram fails, the on-board signal system of the first tram can be updated while the first tram is running, which is advantageous for improving the safety while the tram is running.
Referring to fig. 2, fig. 2 is a schematic flowchart of a second embodiment of an update method for a vehicle-mounted signal system of a tram based on UWB according to an embodiment of the present application. In a second embodiment, a plurality of UWB wayside devices are arranged at intervals along the length direction of a tram track beside the track, and each UWB wayside device is provided with a first UWB antenna. As shown in fig. 2, the update method of the vehicle-mounted signal system of the UWB-based tram may include the steps of:
201. the dispatching command center monitors whether a vehicle-ground communication device included in a vehicle-mounted signal system of a first tramcar running on the tramcar track breaks down or not, if so, detects whether a second tramcar running in front of the first tramcar exists on the tramcar track or not and whether a vehicle-ground communication device included in the vehicle-mounted signal system of the second tramcar is normal or not, and if so, sends information to be updated corresponding to the vehicle-ground communication device included in the vehicle-mounted signal system of the first tramcar to the vehicle-ground communication device included in the vehicle-mounted signal system of the second tramcar.
As an optional implementation manner, after the dispatching command center monitors that a vehicle-ground communication device included in a vehicle-mounted signal system of a first tramcar running on the tramcar track has a fault, the dispatching command center may further determine whether information to be updated corresponding to the vehicle-mounted signal system of the first tramcar exists in a local database, and if not, end the process; if so, the step of detecting whether a second tram running in front of the first tram exists on the tram track and the vehicle-ground communication equipment included in the vehicle-mounted signal system of the second tram is normal is executed.
202. The second tramcar acquires information to be updated corresponding to the vehicle-mounted signal system of the first tramcar from vehicle-ground communication equipment included in the vehicle-mounted signal system of the second tramcar, and when the distance between a second UWB antenna arranged at the front end of the train head of the second tramcar and a first UWB antenna of a first target UWB roadside device to be driven is calculated to be smaller than or equal to a preset distance threshold value during the track running of the tramcar, the information to be updated corresponding to the UWB of the vehicle-mounted signal system of the first tramcar is sent to the first UWB antenna of the first target UWB roadside device through the second UWB antenna, so that the first target UWB roadside device stores the information to be updated corresponding to the vehicle-mounted signal system of the first tramcar; the first target UWB wayside device belongs to a UWB wayside device of the plurality of UWB wayside devices that is closest to the second tram that the second tram has not yet driven.
203. When the distance between a third UWB antenna arranged at the front end of the train head of the first tramcar and a first UWB antenna of the first target UWB roadside device to be driven to is calculated by the first tramcar on the way of the tramcar track running and is smaller than or equal to the preset distance threshold, a request for acquiring information to be updated is sent to the first UWB antenna of the first target UWB roadside device through the third UWB antenna.
204. The first tramcar acquires the information to be updated corresponding to the vehicle-mounted signal system of the first tramcar, which is sent by the first target UWB roadside device through the first UWB antenna of the first target UWB device, through the third UWB antenna.
205. And the first tramcar correspondingly updates the vehicle-mounted signal system of the first tramcar according to the information to be updated corresponding to the vehicle-mounted signal system of the first tramcar.
206. When the first tramcar calculates that the distance between the third UWB antenna and the first UWB antenna of the second target UWB roadside device to be driven is smaller than or equal to the preset distance threshold value during the tramcar track driving process, the first tramcar sends vehicle-mounted signal system updating completion response information of the first tramcar to the first UWB antenna of the second target UWB roadside device through the third UWB antenna so that the second target UWB roadside device stores the vehicle-mounted signal system updating completion response information of the first tramcar; wherein the second target UWB roadside device is another UWB roadside device that is located in front of the first target UWB roadside device and closest to the first target UWB roadside device in the traveling direction of the first tram, of the plurality of UWB roadside devices.
207. When a third tramcar calculates that the distance between a fourth UWB antenna arranged at the front end of the car head of the third tramcar and a first UWB antenna of the second target UWB roadside device to be driven to is smaller than or equal to the preset distance threshold value in the process of running of the tramcar track, an information acquisition instruction is sent to the first UWB antenna of the second target UWB roadside device through the fourth UWB antenna; wherein the third tram is traveling on the tram track and is located behind the first tram.
208. And the third tramcar acquires the vehicle-mounted signal system updating completion response information of the first tramcar, which is sent by the second target UWB roadside device through the first UWB antenna of the second target UWB roadside device according to the information acquisition request, through the fourth UWB antenna.
209. And the third tramcar reports the updated response information of the vehicle-mounted signal system of the first tramcar to the dispatching command center through vehicle-ground communication equipment included in the vehicle-mounted signal system of the third tramcar.
As an optional implementation manner, after the third tram acquires, through the fourth UWB antenna, vehicle-mounted signal system update completion response information of the first tram, which is sent by the second target UWB wayside device through the first UWB antenna of the second target UWB wayside device according to the information acquisition request, the following steps may be further performed:
the third tram detects whether the vehicle-ground communication equipment included in the vehicle-mounted signal system of the third tram is normal, and if the vehicle-ground communication equipment is normal, step 209 is executed; on the contrary, if the third tram detects that the vehicle-ground communication equipment included in the vehicle-mounted signal system of the third tram is abnormal, the vehicle-mounted signal system update completion response information of the first tram may be discarded.
In the above steps 206 to 209, the vehicle-ground communication device included in the vehicle-mounted signal system of the third tram running on the tram track and located behind the first tram may report the vehicle-mounted signal system update completion response information of the first tram to the dispatching command center, so that the dispatching command center may also know that the vehicle-ground communication device in the vehicle-mounted signal system of the first tram has failed as soon as possible, thereby avoiding the same configuration from being repeatedly performed on the vehicle-mounted signal system of the tram during tram running, and facilitating improvement of safety during tram running.
It can be seen that, by implementing the method described in fig. 2, even if the vehicle-ground communication device in the on-board signal system of the first tram fails, the on-board signal system of the first tram can be updated while the first tram is running, which is advantageous for improving the safety while the tram is running. In addition, the implementation of the method described in fig. 2 can avoid repeated and identical configuration of the on-board signal system of the tram during tram running, which is beneficial to improving safety during tram running.
