Embodiment 2

[0136] This embodiment is a further description of Embodiment 1. For the same or similar parts as Embodiment 1, please refer to the relevant description of Embodiment 1 for details, and details will not be repeated here. Such as image 3 As shown, the OBU bluetooth communication in this embodiment also includes:

[0137] S105. When a Bluetooth start command is received, start the Bluetooth device.

[0138] Specifically, when the Bluetooth device is not activated, the OBU Bluetooth device does not have the function of forwarding vehicle road information. When the Bluetooth start command sent by the user is received, the OBU Bluetooth device can be started according to the Bluetooth start command, so that when the OBU Bluetooth device is started, the state of the Bluetooth subscription function can be updated according to the instruction sent by the user terminal.

[0139] As an example and not limitation, the user can generate a Bluetooth start command by performing various o...

Embodiment 3

[0154] Figure 4 It shows a schematic flowchart of the OBU Bluetooth communication method provided by the present application. As an example but not a limitation, the method can be applied to the RSU, and the RSU is connected to the OBU in communication.

[0155] The above-mentioned OBU Bluetooth communication method includes:

[0156] S201. When it is detected that the vehicle arrives at a preset position, send a Bluetooth status information acquisition instruction to the OBU of the vehicle, and receive the Bluetooth status information returned by the OBU.

[0157] Specifically, when detecting that the vehicle arrives at a preset location, the RSU needs to send an information acquisition instruction to the OBU. Wherein, the information obtaining instruction includes but not limited to the vehicle information obtaining instruction and the Bluetooth state information obtaining instruction, and is used to obtain the vehicle information and the Bluetooth state information of the...

Embodiment 4

[0167] This embodiment is a further description of the third embodiment. For the same or similar parts as the third embodiment, please refer to the relevant description of the third embodiment for details, and details will not be repeated here. Such as Figure 5 As shown, in this embodiment, when it is detected that the Bluetooth status information and the type of the RSU meet the preset conditions, a Bluetooth startup command is generated, including:

[0168] S2021. When it is detected that the type of the RSU is the first preset type, check whether the Bluetooth status information satisfies a first preset condition; wherein the Bluetooth status information includes Bluetooth service subscription information.

[0169] Specifically, the Bluetooth state information includes, but is not limited to, Bluetooth service subscription information and Bluetooth state variables. The first preset type means that the RSU only needs to determine whether it needs to control the OBU Bluetoo...

Abstract

The invention is suitable for the technical field of Bluetooth communication, and provides an OBU Bluetooth communication method and device, an OBU and an RSU. The method comprises the following steps: starting a Bluetooth device and establishing a Bluetooth connection relation between the Bluetooth device and a user terminal when a Bluetooth subscription function is detected to be started and a Bluetooth starting command sent by the RSU is received, and starting a Bluetooth connection relation between the Bluetooth device and the user terminal when vehicle road information sent by the RSU is received. And sending the vehicle and road information to the user terminal, and turning off the Bluetooth device when detecting that the vehicle and road information is sent completely. According to the invention, the Bluetooth device can be started only when needed, the power consumption of the Bluetooth device is reduced, and the communication efficiency between the OBU and other terminal equipments is improved.

Description

technical field [0001] The present application belongs to the technical field of bluetooth communication, and in particular relates to an OBU bluetooth communication method, device, OBU and RSU. Background technique [0002] The electronic toll collection system ETC is an intelligent transportation system, which mainly includes the roadside unit (Road SideUnit, RSU) and the on-board unit (On Board Unit, OBU). In recent years, the electronic toll collection system ETC is often used to implement ETC toll service and vehicle-road coordination service. [0003] However, the related method of implementing vehicle-road coordination services based on OBU Bluetooth usually requires a large amount of power consumption of OBU equipment, resulting in the inability to send vehicle-road information to other terminals in real time and effectively, and the communication efficiency is low. Contents of the invention [0004] The embodiment of the present application provides an OBU blueto...
