Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, specific embodiments of the present disclosure are described below in detail with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a schematic flowchart of a vehicle position obtaining method according to an embodiment of the present disclosure. The method is applied to the bus-mounted terminal. As shown in fig. 1, the method includes the following step S101:
s101, when a bus arrives at a stop, the vehicle-mounted terminal sends the unique identification of the bus to the bus stop board at the stop through close-range communication, so that the bus stop board at the stop receives the unique identification of the bus and then knows the information that the bus arrives at the stop, the information that the bus arrives at the stop is sent to all adjacent bus stop boards through D2D communication, and then each adjacent bus stop board continues to transmit the information that the bus arrives at the stop to the adjacent bus stop board through D2D communication until all the bus stop boards receive the information that the bus arrives at the stop.
Wherein, every bus all has the unique sign of vehicle to be different from other buses. For a certain stop, all buses on the same line only communicate with the bus stop boards on the corresponding line of the stop in a short distance, for example, all 39 buses communicate with the 39 bus stop boards on the stop in a short distance. Moreover, the adjacent bus stop boards communicated through the D2D are all bus stop boards of the same line, for example, all bus stop boards are 39 lines; the D2D communication may specifically employ the 5G D2D communication technology.
The near field communication technology can adopt Bluetooth (Bluetooth) or ZigBee, and the transmission frequency bands of the Bluetooth and the ZigBee are both 2.4 GHz. Because bluetooth and zigBee are present mature technology, no longer give unnecessary details here.
The Device-to-Device name of D2D refers to Device-to-Device, and may be referred to as terminal-through. The D2D communication technology refers to a communication method for directly communicating between two peer user nodes. In the distributed network consisting of D2D communication users, each user node can send and receive signals and has the function of automatic routing (forwarding messages). Participants of the network share a portion of the hardware resources they own, including information processing, storage, and network connectivity capabilities. These shared resources provide services and resources to the network that can be accessed directly by other users without going through intermediate entities. In the D2D communication network, user nodes play the roles of both a server and a client, and users can realize the existence of each other and form a virtual or actual group in a self-organizing way.
In the embodiment of the disclosure, when a bus arrives at a certain stop, the vehicle-mounted terminal sends the unique identification of the bus to the bus stop board of the stop through close-range communication, so that the bus stop board of the stop knows the information that the bus arrives at the stop (for example, 39-way No. 001 bus arrives at stop B), and then the bus stop board of the stop transmits the information that the bus arrives at the stop to the adjacent bus stop boards through D2D communication until all the bus stop boards receive the information that the bus arrives at the stop; of course, if the same bus arrives at the next stop, all the bus stop boards receive the information that the bus arrives at the next stop, and at the moment, all the bus stop boards should update the information that the bus arrives at the stop, that is, only the latest received information that the bus arrives at the stop is reserved. It can be seen that, when a bus arrives at a stop, all the bus stop boards can acquire the information that the bus arrives at the stop, in other words, after each bus on the same line arrives at the corresponding stop, all the bus stop boards can acquire the information that each bus on the same line arrives at the stop, which is equivalent to all the bus stop boards sharing the information that each bus arrives at the stop.
Fig. 2 is a schematic flow chart of another vehicle position obtaining method according to the embodiment of the disclosure. The method is applied to a bus stop board system, and comprises a plurality of bus stop boards distributed at each stop, wherein each bus stop board corresponds to one stop. As shown in fig. 2, the method includes the following steps S201 to S203.
S201, after a bus arrives at a certain stop, a bus stop board of the stop receives a unique vehicle identification of the bus sent by a vehicle-mounted terminal of the bus through near field communication, and information that the bus arrives at the stop is obtained based on the unique vehicle identification;
s202, the bus stop board of the stop sends the information of the bus arrival stop to all adjacent bus stop boards through D2D communication;
s203, each adjacent bus stop board continuously transmits the information of the bus arrival station to the adjacent bus stop board through D2D communication until all the bus stop boards receive the information of the bus arrival station.
In step S202, it is possible for the stop to be an origin, an intermediate or a destination on a bus route. If the bus station is a starting station or a terminal station, only one bus station board is arranged adjacent to the bus station board of the station, and the bus station board of the station transmits the information of the bus arriving at the station to only one adjacent bus station board through D2D communication; if the bus stop board is the middle station, two bus stop boards adjacent to the bus stop board of the station exist, and the bus stop board of the station sends the information of the bus arrival station to the two adjacent bus stop boards through D2D communication.
In the embodiment of the disclosure, after a bus arrives at a certain stop, the bus stop board at the stop can receive the unique identification of the bus sent by the vehicle-mounted terminal through close-range communication, so that the bus arrival stop information is known, and then the bus stop board at the stop transmits the bus arrival stop information to the adjacent bus stop boards through D2D communication until all the bus stop boards receive the bus arrival stop information, so that all the bus stop boards share the bus arrival stop information obtained by themselves. Of course, if the same bus arrives at the next stop, all the bus stop boards receive the information that the bus arrives at the next stop, and at the moment, all the bus stop boards should update the information that the bus arrives at the stop, that is, only the latest received information that the bus arrives at the stop is reserved.

If the station where the 001-number bus arrives in step S201 is the station a, the bus stop board at the station a in step S202 sends the information that the 001-number bus arrives at the station a to the bus stop board at the only adjacent station B, the bus stop board at the station B in step S2031 has the result that the bus stop board to which the information that the 001-number bus arrives at the station a is the bus stop board at the next station on the bus route, and step S2035 is executed to continuously determine whether the station where the bus stop board at the station B is located is the terminal station, and if not, the steps S2036 to S2037 are repeatedly executed, and the information that the 001-number bus arrives at the station a is sequentially transmitted to all stations in front of the station B through D2D communication until the information is transmitted to the terminal station Z.
If the station where the 002 bus arrives is the Z station in step S201, the bus stop board at the Z station in step S202 sends the information that the 002 bus arrives at the Z station to the bus stop board at the only adjacent Y station, the bus stop board at the Y station in step S2031 has the judgment result that the bus stop board to which the information that the 002 bus arrives at the Z station is sent is the bus stop board at the previous station on the bus route, and step S2032 is executed, whether the station where the bus stop board at the Y station is located is the departure station is continuously judged, and the judgment result is that the station is not the departure station, steps S2033 to S2034 are repeatedly executed, and the information that the 002 bus arrives at the Z station is sequentially transmitted to all stations behind the Y station through D2D communication until the information is transmitted to the departure station a.
If the station where the No. 003 bus arrives is the station D in the step S201, the bus stop board at the station D in the step S202 sends information that the No. 003 bus arrives at the station D to the bus stop board at the adjacent station C and the bus stop board at the adjacent station E respectively, the bus stop board at the station C in the step S2031 has the judgment result that the bus stop board to which the information that the No. 003 bus arrives at the station D is the bus stop board at the station before the bus stop board on the bus route, the step S2032 is executed, whether the station where the bus stop board at the station C is located is the starting station is continuously judged, and the judgment result is not the starting station, the steps S2033 to S2034 are repeatedly executed, and the information that the No. 003 bus arrives at the station D is sequentially transmitted to all stations behind the station C through the communication of the D2D until the information is transmitted to the starting station A; meanwhile, in step S2031, the bus stop board at the E stop is the bus stop board at the next stop on the bus route to which the information that the No. 003 bus arrives at the D stop is sent, and step S2035 is executed, whether the stop where the bus stop board at the E stop is located is the end stop is continuously judged, and if the judgment result is not the end stop, steps S2036 to S2037 are repeatedly executed, and the information that the No. 003 bus arrives at the D stop is sequentially transmitted to all stops in front of the E stop through D2D communication until the information is transmitted to the end stop Z.
