Description

Control method and device of vehicle-mounted unit, storage medium and electronic device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and apparatus for controlling an on-board unit, a storage medium, and an electronic apparatus.

Background

In a highway system, the traffic speed of a vehicle flowing freely at a high speed is much higher than that of an entrance or an exit of an electronic toll collection (Electronic Toll Collection, abbreviated as ETC) lane, in order to increase the transaction success rate of the ETC portal free flow toll collection, the signal coverage area of a portal Side Unit (RSU) antenna is generally set to be about 80 meters, the wake-up sensitivity of an On Board Unit (OBU) is generally about-45 dBm to 52dBm, and the signal coverage area of 80m can be achieved by matching with the adjustment of the antenna pitch angle when the emission power of the RSU antenna is usually at the maximum. The wake-up sensitivity of the OBU of some manufacturers is higher, the wake-up receiving area of the OBU can even reach 100m, the transmitting power of the OBU is generally less than 10dBm, and the receiving sensitivity of the antenna is also limited by the technology, so that after the OBU enters the coverage area of the RSU antenna and is waken up by the wake-up signal transmitted by the RSU antenna, the OBU transmits a reply signal, and the RSU antenna cannot receive the reply signal of the OBU, so that the OBU can continuously reply the same signal in the area 100 m-40 m away from the antenna, and the power consumption of the OBU is increased, namely, 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 succeeds, the OBU is also in a high power consumption state continuously awakened by the RSU antenna. On the one hand, if the OBU transaction is successful and does not exit the coverage area of the antenna signal, the RSU antenna continuously transmits a beacon service table (Beacon Service Table, BST for short) signal without changing beacon service table identifier BeaconID, and the OBU continuously and repeatedly enters a state of waking-recognizing BST-sleeping, so that the power consumption of the OBU is increased; on the other hand, after the RSU antenna on the portal fails to transact with other OBUs, the beacon id in the signal transmitted by the antenna is usually changed, after a certain OBU transacts successfully and does not exit the coverage area of the antenna signal, the antenna continuously transmits the BST with the beacon id changed, so as to cause the OBU to continuously reply the signal, and the RSU antenna considers that the OBU transacts successfully and therefore refuses to reply the OBU, so that the same situation as when the OBU just enters the coverage area of the antenna of the RSU is caused, namely, 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 passes through the portal RSU antenna normally for a single time, there is additional high power consumption except for the power consumption of normal transaction, so that the service life of the OBU is shortened, and more serious, when the traffic jam occurs under the ETC portal area of the vehicle provided with the OBU, the OBU is continuously in a high power consumption state, so that the service life of the OBU is greatly influenced.

Aiming at the technical problem that the power consumption of the vehicle-mounted unit in the signal coverage area of the RSU antenna is high in the related art, an effective technical scheme is not proposed yet.

step S102, determining whether a target vehicle-mounted unit accords with a preset condition according to a first beacon service table BST signal received by the target vehicle-mounted unit, wherein the preset condition is a condition for indicating the target vehicle-mounted unit to switch to a target state;

step S104, determining a first duration corresponding to the target state under the condition that the target vehicle-mounted unit accords with the preset condition;

and step S106, controlling the target vehicle-mounted unit to switch to the target state and keeping the target state for the first duration, wherein the target vehicle-mounted unit is not awakened in the target state.

It should be noted that, the above embodiment may be applied to an ETC free flow scenario, that is, the method in the above embodiment may control a vehicle-mounted unit installed in a vehicle in the ETC free flow scenario, so as to save power consumption of an OBU in the ETC free flow scenario. The target on-board unit receives a first BST signal from the target roadside unit, namely, the target on-board unit is located in the signal coverage area of the roadside unit antenna.

In the above embodiment, the first BST signal is a signal received from the target roadside unit. The target state is also referred to as a low power consumption frozen state, in which the on-board unit is in a low power consumption state and does not receive the wake-up signal (i.e., the RSU signal in the above embodiment) sent by the RSU, so that the on-board unit in the target state is not woken up by the road side unit, i.e., the on-board unit in the target state is in a low power consumption state that is not woken up by the wake-up signal sent by the RSU. The wake-up signal sent by the road side unit is used for waking up the vehicle-mounted unit.

Wherein the Beacon identity is the Beacon id. After the target virtual resource is successfully transferred, the target vehicle-mounted unit generates and stores a transfer log corresponding to the target virtual resource. Optionally, the successful transfer of the target virtual resource corresponding to the target on-board unit may include payment of completion of the order corresponding to the target on-board unit (for example, payment of transaction completed by the on-board unit), that is, the time when the transfer of the target virtual resource corresponding to the target on-board unit in the above embodiment is successful may include the time when the transaction of the order of the target on-board unit is completed, and the transfer log corresponding to the target virtual resource may include a transaction log, that is, the Beacon identifier recorded in the transfer log is a Beacon id in the BST signal when the transaction of the target on-board unit is completed.

It should be noted that, in the above embodiment, the preset time period is a fixed-length time period, that is, the length of the preset time period is fixed, for example, 255s. Alternatively, the first time period may be a value between 100ms and 30 s. As shown in fig. 2, the start time of the preset time period is t0, the length is t4-t0, the first BST signal is received at a certain time t1 in the preset time period, and when it is determined that the target vehicle-mounted unit meets the preset condition, the target vehicle-mounted unit is controlled to be in the target state and kept for a first duration.

Based on the above embodiment, after the target on-board unit is in the target state, the start time and the end time of the preset time period are updated, and after the target on-board unit ends the target state, the target on-board unit is controlled to be in a preset sleep state between the end time of the first duration corresponding to the target state and the end time of the preset time period (i.e., the end time after the update of the preset time period), where the preset sleep state may be a sleep state (also referred to as a sleep state) of the on-board unit in the related art, and in the preset sleep state, the target on-board unit may receive the wake-up signal sent by the road side unit and may be awakened by the received wake-up signal. As shown in fig. 3, the starting time of the preset time period is updated to be the time indicated by the timestamp in the first BST signal (i.e., t 1), the ending time of the preset time period is updated to be t5 according to the length of the preset time period, when the ending time t3 of the first duration is reached, the target vehicle-mounted unit is controlled to be in a preset dormant state in the time from t3 to t5, and in the time from t3 to t5, if the Beacon identifier in the second BST signal received by the target vehicle-mounted unit is the same as the target Beacon identifier, the target vehicle-mounted unit is controlled to enter the target state again.

Optionally, the target time period is a single wake-up time interval of the target on-board unit, that is, a time interval between when the target on-board unit is woken up by the BST signal and is woken up again by the BST signal after being in the sleep state, so that the BST signal with the first Beacon identifier received in the target time period in the above embodiment is a signal received by the target on-board unit in the single wake-up time interval.

It should be noted that, in the above alternative embodiment, after each time it is determined that the target on-board unit is switched to the target state, a beacon id (for example, a beacon id in the first BST signal and a beacon id in the second BST signal in the above embodiment) triggering the target on-board unit to switch to the target state and a determined duration corresponding to the target state are stored in the target on-board unit, and when it is determined that the target on-board unit is switched to the target state again according to a certain BST signal, a duration corresponding to the last target state corresponding to the beacon id in the certain BST signal is found from the stored data, and a duration corresponding to the target state of the target on-board unit at this time is determined based on the duration.

In an alternative embodiment, before determining whether the target on-board unit meets the preset condition, the method further includes: at least one preset condition and a one-to-one correspondence between each preset condition in the at least one preset condition and a default time length are configured, wherein the default time lengths corresponding to different preset conditions are different.

Wherein, in the case that the third duration is not found, the method further includes: acquiring a default time length corresponding to the preset condition met by the target vehicle-mounted unit, and determining the acquired default time length as the first time length.

Optionally, for preset conditions: the method comprises the steps that the time difference between the ending time corresponding to one Beacon identifier and the starting time corresponding to the Beacon identifier exceeds a first default time length corresponding to a time difference threshold, and the preset conditions are as follows: and the reply times corresponding to the Beacon identifiers which are different from the target Beacon identifiers exceed a second default time length corresponding to the time threshold, and the second default time length is smaller than or equal to the first default time length.

In the related art, when the OBU enters the signal coverage area of the portal RSU antenna, the OBU enters the 5.8G service processing flow due to the wake-up signal of 5.8G, receives the downlink frame data sent by the RSU antenna, and processes and replies according to the received data command. After the OBU is awakened by the 5.8G signal, the OBU can receive and correctly decode BST signal data sent by the RSU antenna, and a main control module of the OBU can process a data command in the BST signal and reply a vehicle service table (Vehicle Service Table, VST) frame signal with a media access control identifier (Media Access Control Address Identity, MACID) of the OBU; if the RSU antenna receives the VST signal with the MACID, the RSU antenna can send a new frame signal to further interact with the OBU completion information with the MACID, so that transaction fee deduction is completed. When vehicles provided with OBUs of different manufacturers are blocked under a portal RSU antenna, or the OBU is successful in transaction, a high power consumption state exists, and on one hand, continuous BST-VST signals are sent out, namely, the high power consumption state after normal transaction; on the other hand, if the OBU recognizes a successful transaction, 255s will be kept without replying to the BST signal with the same beacon id, but the OBU is continuously awakened by the signal sent by the RSU, and the OBU receives the BST signal and judges that the BST signal is the same beacon id and then enters sleep.

In an alternative embodiment of the present invention, after the OBU transaction is successful, when it is detected that the OBU is awakened by the BST signal having the same beacon id as that of the transaction success, it is determined that the OBU is in a power-on-power-consumption state, and the low-power-consumption freezing module controls the OBU to enter a low-power-consumption freezing state (i.e., the target state in the above embodiment) within a certain period of time according to the detected power-on-power-consumption state. After the OBU is awakened, if the OBU receives the BST signal same as the Beacon id (i.e., the target Beacon identifier in the above embodiment) when the transaction is completed in a preset period of time, the OBU immediately exits the radio frequency service flow, so that the OBU enters a low-power-consumption frozen state in the shortest time and keeps for a certain period of time. Optionally, the preset time period is a fixed 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 the BST signals with the same beacon id are received within the preset time period, the start time of the preset time period is updated to the time of the newly received BST signals with the same beacon id (optionally, the time indicated by the Unix timestamp in the newly received BST signals 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, recording the time of the BST signal with a certain beacon id received by the OBU (for example, the time indicated by the timestamp in the BST signal), determining the time as the start time of the beacon id, and when the BST signal with the beacon id continues to be received and the OBU replies to the corresponding VST reply signal, recording the time indicated by the timestamp in the BST signal for the VST reply signal as the end time corresponding to the beacon id, and when the difference value between the end time corresponding to the beacon id and the start time corresponding to the beacon id is greater than or equal to the time difference threshold, controlling the OBU to enter the low power consumption frozen state of the fourth duration. For example, in the related art, when an OBU is blocked before a transaction with an RSU, the transmission power of the mast RSU antenna is high, so after a part of the OBU is awakened, the BST signal sent by the mast RSU antenna is received and the VST signal is recovered, and the mast antenna may not receive the reply signal of the OBU because of insufficient receiving sensitivity, which results in that the OBU continuously replies the VST signal and thus high power consumption is caused. In an alternative embodiment of the present invention, the OBU takes the Unix timestamp of the BST signal of a certain beacon id as the start time of the beacon id, takes the Unix timestamp in the BST signal of the same beacon id as the end time of the beacon id when the BST signal of the same beacon id is received and the VST signal is replied, and updates the BST end time of the beacon id in real time each time the BST signal of the same beacon id is received; when BST signals with different Beacon IDs are received, the different Beacon IDs are used as decision basis, the time stamp of the BST signals with the different Beacon IDs is saved as the starting time of the different Beacon IDs, the corresponding ending time of the different Beacon IDs is updated again according to the different Beacon IDs in a circulating way, and when the difference value between the ending time and the starting time of the different Beacon IDs is larger than or equal to a time difference threshold value, the OBU enters a low-power consumption freezing 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: after the OBU with a certain MACID is successful under the portal RSU antenna, when the OBU detects that BST signals with other Beacon IDs (such as Beacon ID 1) different from the Beacon ID when the transaction is successful are received, the BST signals of the Beacon ID1 are continuously received and the VST signals with more than preset times are recovered, and when other downlink frames about the OBU are not received, the OBU is considered to be in a state of high power consumption, and the low power consumption freezing module controls the OBU to enter the low power consumption freezing state and keep for a certain period of time according to the detected state of high power consumption. After the OBU finishes the transaction, receiving a BST signal with a Beacon ID different from the Beacon ID when the transaction is successful in a preset time period, recording the number of times of replying the VST signal when the OBU receives the BST of the same and different Beacon ID (e.g. Beacon ID 1) in a single wake-up time interval, and when the number of times of replying the VST is larger than a number-of-times threshold, entering a low-power-consumption freezing state and keeping for a certain period of time; the number threshold can be a value from 1 to 10, and the larger the number threshold is, the larger the overall traffic jam power consumption after OBU transaction is; the smaller the number threshold value is, the smaller 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 detection result (including a beacon id in a BST signal received by the on-board unit) of the power generation detected by the power generation detection module when the OBU wakes up last time and a duration (i.e., a low-power freezing time) corresponding to the low-power freezing state, and setting a longer low-power freezing time when the beacon id in the detection result of the power generation detection module is the same as the last power generation result; the detection result of the current power generation detection module is different from the previous power generation condition, and the initial low-power consumption freezing time is correspondingly set.
