Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for controlling a vehicle-mounted unit, a storage medium, and an electronic apparatus.
Background
In an expressway system, the passing speed of vehicles flowing at high speed freely is much higher than that of an entrance or an exit of an Electronic Toll Collection (ETC) lane, in order to increase the transaction success rate of ETC portal free flow charging, the signal coverage area of a portal Road Side Unit (RSU) antenna is generally set to be about 80 meters, the awakening sensitivity of an On Board Unit (OBU) is generally about-45 dBm-52 dBm, and when the transmitting power of the RSU antenna is maximum, the RSU antenna is matched with the adjustment of the pitch angle of the antenna, so that the signal coverage area of 80m can be reached. The wake-up sensitivity of the OBU of some manufacturers is high, the wake-up receiving area of the OBU even reaches 100m, the transmission power of the OBU is generally less than 10dBm, and the receiving sensitivity of the antenna is also limited by technology, so that the OBU sends back a reply signal after entering the RSU antenna coverage area and being woken up by the wake-up signal transmitted by the RSU antenna, and the RSU antenna cannot receive the reply signal of the OBU, so that the OBU can continuously reply the same signal in an area 100-40 m away from the antenna, and the power consumption of the OBU is increased, that is, the OBU enters a high power consumption (or high power consumption) state.
And after the normal transaction of the RSU and the OBU on the ETC portal frame is successful, the OBU is also in a high power consumption state which is continuously awakened by the RSU antenna. On one hand, if the OBU does not exit the antenna signal coverage area after successful transaction, the RSU antenna continuously sends a Beacon Service Table (BST) signal without changing the Beacon ID of the Beacon Service Table, and the OBU continuously and repeatedly enters a state of awakening-identifying BST-sleeping, so that the power consumption of the OBU is increased; on the other hand, after the transaction between the RSU antenna on the portal and other OBUs is failed, the BeaconID in the signal transmitted by the antenna is usually changed, after a certain OBU is successfully transacted and does not exit the antenna signal coverage area, the antenna continuously transmits BST with changed BeaconID, so that the OBU continuously replies a signal, and the RSU antenna considers that the OBU is successfully transacted and therefore refuses to reply the OBU, so that the same condition as when the OBU just enters the antenna coverage area of the RSU is caused, that is, the OBU continuously replies the same signal to the RSU antenna.
Therefore, in the related art, because the signal coverage area of the ETC portal RSU antenna is too large, when the OBU normally passes through the portal RSU antenna at a single time, extra high power consumption except for the power consumption of normal transaction exists, so that the service life of the OBU is shortened, and more seriously, when a vehicle provided with the OBU is in a traffic jam condition in the area of the ETC portal, the OBU can be continuously in a high power consumption state, so that the service life of the OBU is greatly influenced.
In the related art, no effective technical scheme is provided for the technical problem that the power consumption of the vehicle-mounted unit is high in the signal coverage area of the RSU antenna.

Alternatively, the control method of the on-board unit in the above embodiment may be applied to the apparatus shown in fig. 5, which includes a main control module, a radio frequency module, a power consumption detection module, and a low power consumption freezing module, wherein,
the main control module is respectively connected with the radio frequency module, the power consumption detection module and the low-power consumption freezing module, is responsible for the main functions and logic processing of the OBU, and can complete a 5.8G transaction fee deduction process through the radio frequency module and the RSU antenna;
the power consumption detection module is used for detecting whether the OBU generates power consumption in the antenna area;
the low-power consumption freezing module is used for confirming that the OBU enters a low-power consumption freezing state and freezing holding time corresponding to the low-power consumption freezing state according to a detection result of the power generation and consumption detection module, when the OBU is in the low-power consumption freezing state, the OBU cannot respond to a 5.8G radio frequency wake-up signal (also called a 5.8G radio frequency wake-up interrupt wake-up signal), namely the OBU cannot be woken up, and microampere standby current in the OBU (namely the OBU is in a low-power consumption standby state which is not woken up) is provided, and when the set freezing holding time is over, the OBU continues to keep the low-power consumption state (namely the preset sleep state in the embodiment) and can respond to the 5.8G radio frequency wake-up interrupt.
In the related art, when the OBU enters a signal coverage area of the gantry RSU antenna, the OBU enters a 5.8G service processing procedure due to a 5.8G wake-up signal, receives downlink frame data sent by the RSU antenna, and performs processing and replying according to a received data instruction. Generally, after the OBU is awakened by the 5.8G signal, the OBU can receive and correctly decode BST signal data transmitted by the RSU antenna, and the main Control module of the OBU can process a data command in the BST signal and reply a Vehicle Service Table (VST) frame signal with a Media Access Control Identity (MACID) of the OBU; if the RSU antenna receives the VST signal with the MACID, the RSU antenna sends a new frame signal to further complete information interaction with the OBU with the MACID, and therefore transaction deduction is completed. When the vehicle provided with the OBUs of different manufacturers is blocked under the portal RSU antenna or the OBU transaction is successful, a high power consumption state exists, namely continuous BST-VST signal transmission, namely the high power consumption state after normal transaction; on the other hand, if the OBU recognizes a successful transaction, 255s are kept not to reply to the BST signal with the same beacon id, but the OBU is continuously woken up by the signal sent by the RSU, and the OBU receives the BST signal and determines that the beacon id is the same and then goes to sleep.
In an optional embodiment of the present invention, after the OBU transaction is successful, when it is detected that the OBU is woken up by the BST signal having the same BeaconID as that when the transaction is successful, it is determined that the OBU is in a power consumption on-demand state, and the low power consumption freezing module controls the OBU to enter the low power consumption freezing state (i.e., the target state in the above embodiment) within a certain time period according to the detected power consumption on-demand state. After the OBU is awakened, the OBU immediately exits the radio frequency service flow when receiving a BST signal that is the same as the Beacon id (i.e., the target Beacon identifier in the above embodiment) at the time of completing the transaction within a preset time period, so that the OBU enters a low power consumption frozen state within the shortest time and is kept for a certain time. Optionally, the preset time period is a fixed time duration, for example, 255s, and the start time is a start time when the last transaction is completed, for example, a time indicated by a Unix timestamp carried in a BST signal when the transaction is completed. It should be noted that, when a BST signal with the same beacon id is received within a preset time period, the start time of the preset time period is updated to the time of the newly received BST signal with the same beacon id (optionally, the time indicated by the Unix timestamp in the newly received BST signal with the same beacon id is taken). Optionally, the first duration is a duration between 100ms and 30 s.
Optionally, before or after the OBU and the RSU trade, a time of a BST signal with a certain BeaconID received by the OBU (for example, a time indicated by a timestamp in the BST signal) is recorded and determined as a start time of the BeaconID, and when the BST signal with the BeaconID is continuously received and the OBU replies a corresponding VST reply signal, a time indicated by the timestamp in the BST signal to which the VST reply signal corresponds is recorded as an end time corresponding to the BeaconID, and when a difference between the end time corresponding to the BeaconID and the start time corresponding to the BeaconID is greater than or equal to a time difference threshold, the OBU is controlled to enter a low power consumption frozen state of a fourth duration. For example, in the related art, when the OBU blocks the vehicle before the transaction with the RSU, the transmitting power of the antenna of the gantry RSU is high, so that a part of the OBU is woken up to receive the BST signal transmitted by the antenna of the gantry RSU and reply to the VST signal, and the gantry antenna may not receive the reply signal of the OBU due to insufficient receiving sensitivity, so that the OBU may continuously reply to the VST signal, thereby causing high power consumption. In an alternative embodiment of the present invention, the OBU uses the Unix timestamp of the received BST signal with a certain BeaconID as the start time of the BeaconID, uses the Unix timestamp of the BST signal with the same BeaconID as the end time of the BeaconID when receiving the BST signal with the same BeaconID and replying the VST signal, and updates the BST end time of the BeaconID in real time each time the BST with the same BeaconID is received; when BST signals with different BeaconIDs are received, the different BeaconIDs are used as judgment bases, time stamps of the BST signals with the different BeaconIDs are stored as starting times of the different BeaconIDs, the corresponding ending times of the different BeaconIDs are restarted to circularly update according to the different BeaconIDs, and when the difference value between the ending time and the starting time of the different BeaconIDs is larger than or equal to a time difference threshold value, the OBU enters a low-power-consumption frozen state.
Optionally, when the difference between the ending time and the starting time of the beacon id is smaller than the time difference threshold, the above embodiment further includes: under the portal RSU antenna, after the OBU transaction that has certain MACID succeeds, when the OBU detects that the BST signal of other BeaconID (for example BeaconID1) that has different with the BeaconID when the transaction succeeds is received, and continuously receive the BST signal of BeaconID1 and reply the VST signal more than the preset number of times, and when not receiving other downlink frames about the OBU, think that the OBU is in a to-and-fro high power consumption state promptly, the low-power consumption freezes the module and controls the OBU to enter the low-power consumption frozen state and keep for a certain time according to the to-and-fro high power consumption state that detects. After the OBU completes the transaction, receiving a BST signal with BeaconID different from the BeaconID when the transaction is successful in a preset time period, recording the frequency of replying the VST signal when the OBU receives the BST of the same different BeaconID (such as BeaconID1) in a single awakening time interval, and when the frequency of replying the VST is greater than a frequency threshold value, entering a low-power-consumption frozen state and keeping for a certain time; the number threshold value can be a numerical value from 1 to 10, and the larger the number threshold value is, the larger the overall traffic jam power consumption after the OBU transaction is; the less the frequency threshold value is, the less the high-power-consumption current consumption time of the OBU is, and the smaller the overall traffic jam power consumption after the OBU transaction is.
Optionally, recording a power consumption detection result (including the BeaconID in the BST signal received by the on-board unit) detected by the power consumption detection module when the OBU is waken up last time and a duration (namely, low-power-consumption freezing time) corresponding to the low-power-consumption freezing state, and setting longer low-power-consumption freezing time when the BeaconID in the detection result of the power consumption detection module is the same as the last power consumption result; the detection result of the current power generation and consumption detection module is different from the last power generation and consumption condition, and the initial low-power consumption freezing time is correspondingly set.
