Vehicle-mounted unit control method and device, storage medium and electronic device

Abstract

The invention provides a vehicle-mounted unit control method and device, a storage medium and an electronic device, and the method comprises the steps: determining whether a target vehicle-mounted unit meets a preset condition or not according to a first beacon service table BST signal received by the target vehicle-mounted unit; under the condition that the target vehicle-mounted unit meets the preset condition, determining a first duration corresponding to the target state; controlling the target vehicle-mounted unit to be switched to the target state, and keeping the target state within thefirst duration, wherein the target vehicle-mounted unit is not awakened in the target state. According to the invention, the technical problem of high power consumption of the vehicle-mounted unit inthe signal coverage area of the RSU antenna in the prior art can be solved, the power consumption of the vehicle-mounted unit in the signal coverage area of the RSU antenna is reduced, and the service life of the vehicle-mounted unit is prolonged.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a control method and device for a vehicle-mounted unit, a storage medium and an electronic device. Background technique [0002] In the highway system, the speed of vehicles under high-speed free flow is much higher than that at the entrance or exit of the Electronic Toll Collection (ETC) lane. In order to increase the transaction success rate of ETC gantry free flow , the signal coverage area of ​​the gantry road side unit (Road Side Unit, referred to as RSU) antenna is generally set to about 80 meters, and the wake-up sensitivity of the on board unit (referred to as OBU) is generally about -45dBm ~ 52dBm , usually when the transmit power of the RSU antenna is turned on to the maximum, combined with the adjustment of the antenna pitch angle, the signal coverage area of ​​80m can be achieved. The OBU wake-up sensitivity of some manufacturers is relatively high, and the wake-up...

AI Technical Summary

Problems solved by technology

On the one hand, if the OBU transaction is successful and does not drive out of the coverage area of ​​the antenna signal, the RSU antenna will continue to send the Beacon Service Table (BST) signal that does not change the Beacon ID of the Beacon Service Table, and the OBU will continue to repeat Entering the wake-up-recognition BST-sleep state increases the power consumption of the OBU; on the other hand, after the RSU antenna on the gantry fails to communicate with other OBUs, it usually causes the BeaconID in the signal transmitted by the antenna to change. After an OBU transaction is successful and does not drive out of the antenna signal coverage area, the antenna will continue to send the BST that changes the BeaconID, which will cause the OBU to continue to reply to the signal, and the RSU antenna will refuse to reply to the OBU because it believes that the OBU has been successfully traded. This results in the same situation as when the OBU first entered the coverage area of ​​the RSU antenna, that is, the OBU continuously replies the same signal to the RSU antenna

[0004] Therefore, in the related art, because the signal coverage area of ​​the ETC gantry RSU antenna is too large, when the OBU normally passes through the gantry RSU antenna once, there will be additional high power consumption in addition to the power consumption of normal transactions, thereby shortening The service life of the OBU is shortened, and what is more serious is that when the vehicle with the OBU installed is in a traffic jam under the ETC gantry area, the OBU will continue to be in a state of high power consumption, which greatly affects the service life of the OBU

[0005] Aiming at the technical problem of the high power consumption of the vehicle-mounted unit in the signal coverage area of ​​the RSU antenna in the related technology, no effective technical solution has been proposed
