Background

An automatic Electronic Toll Collection (ETC) is one of the service functions of an intelligent traffic system, and is particularly suitable for being used in an expressway or a bridge and tunnel environment with busy traffic. The highway toll collection department is provided with a special ETC toll collection channel. The vehicle owner only needs to install the induction card on the front windshield of the vehicle and prestore the fee, the fee is not paid manually when passing through the toll station, the vehicle is not required to be parked, the high-speed toll is automatically deducted from the card, and the automatic charging can be realized. The toll collection system takes less than two seconds per vehicle, and the traffic capacity of the toll collection channel is 5 to 10 times of that of the manual toll collection channel. By using the full-automatic electronic toll collection system, the highway toll collection can be managed in a paperless and cashless manner, the loss phenomenon of toll ticket money is fundamentally avoided, and the problem of disordered financial management in the highway toll collection is solved.

In the ETC system, an On Board Unit (OBU) is arranged On a vehicle, a Road Side Unit (RSU) is erected On a Road Side, and the OBU and the RSU are in communication connection through microwaves. When the vehicle passes through the RSU at high speed, the OBU and the RSU are communicated by microwave to carry out electronic fee deduction. However, when abnormal driving behavior of the vehicle occurs, the toll cannot be normally deducted through the OBU. The abnormal driving behavior of the vehicle is different from the normal driving behavior, for example, the vehicle owner performs the breakthrough in order to achieve the purpose of paying less or not paying the high-speed toll, so that the vehicle speed is too high to identify the OBU, and the normal fee deduction cannot be performed. Or different OBUs are used alternately to achieve the purpose of paying less or not paying high-speed toll, so that overtime payment of the OBUs can be realized. In the related art, the vehicles with abnormal deduction are usually intercepted in a manual inspection mode, so that a large amount of manpower and material resources are required to be input, the efficiency is low, the vehicles with abnormal deduction cannot be controlled quickly and effectively in real time, and the problem of partial loss of the toll can be caused.

Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Fig. 1 is a flowchart illustrating an on-board unit control method according to an embodiment of the present disclosure, where the method may be performed by an on-board unit control system including an on-board unit including a processor, a controller, and a communication device. The communication device is electrically connected with the controller through the processor. The communication device is connected with road side units distributed on different lanes in a communication mode. And the external server is in communication connection with the drive test unit. The on-board unit control system may control the use state of the on-board unit by the on-board unit control method. As shown in fig. 1, the method comprises the steps of:

s110: and acquiring an opening state instruction sent to the vehicle-mounted unit by the external server through the drive test unit.

Because the external server is in communication connection with the drive test unit, the drive test unit can receive the on-state instruction sent by the external server. The drive test unit is in communication connection with the communication device of the vehicle-mounted unit, so that the on-state instruction sent by the external server through the drive test unit can be acquired through the communication device. For example, when the external server detects that the vehicle has abnormal driving behavior, the external server may send an on-state instruction to the drive test unit, and the drive test unit transmits the on-state instruction to the on-board unit. Alternatively, for example, when the external server needs to control the on-board unit, the on-state command may be sent to the on-board unit by the drive test unit.

S210: and controlling the processor of the vehicle-mounted unit to be started based on the starting state instruction.

After the communication device of the vehicle-mounted unit acquires the opening state instruction sent by the external server through the drive test unit, the communication device is electrically connected with the processor, so that the opening state instruction can be sent to the processor through the communication device. The processor of the on-board unit may control the processor to turn on based on the on-state command.

S310: when the processor is started, the use state of the vehicle-mounted unit is controlled by the controller of the vehicle-mounted unit to be adjusted from the normal use state to the abnormal use state.

When the processor is started, the controller of the vehicle-mounted unit can control the use state of the vehicle-mounted unit to be adjusted from the normal use state to the abnormal use state.

Specifically, because the on-board unit is in a normal use state under a normal condition, when the external server detects that the vehicle has abnormal driving behavior or needs to control the on-board unit, the external server may issue an opening state instruction to the on-board unit, the on-board unit opens the processor of the on-board unit according to the opening state instruction, and after the processor is opened, the controller of the on-board unit may adjust the use state of the on-board unit from a normal use state to a non-normal use state. Therefore, the automatic control of the external server to the vehicle-mounted unit can be realized.

Therefore, according to the technical scheme provided by the embodiment of the disclosure, the on-state instruction sent to the vehicle-mounted unit by the external server through the drive test unit is obtained. Therefore, the communication connection between the vehicle-mounted unit and the external server can be realized, so that the vehicle-mounted unit can receive the opening state instruction sent by the external server to the vehicle-mounted unit. The on-board unit may control the processor to turn on based on the on-state instruction. Therefore, the external server can control the opening state of the processor of the vehicle-mounted unit through the opening state instruction, and the purpose that the external server controls the vehicle-mounted unit is achieved. When the processor is started, the controller of the vehicle-mounted unit can control the use state of the vehicle-mounted unit to be adjusted from the normal use state to the abnormal use state. Since the external server can only control the on-board unit processor to be turned on, the controller of the on-board unit cannot be directly controlled, and the controller of the on-board unit is used for controlling the use state of the on-board unit. Therefore, the normal use of the vehicle-mounted unit is not influenced when the processor is not started, namely the vehicle-mounted unit can be normally used when the external server does not control the vehicle-mounted unit, and the vehicle-mounted unit can be controlled not to be normally used when the external server controls the vehicle-mounted unit. Therefore, the vehicles with abnormal fee deduction are not required to be intercepted in a manual inspection mode in the related technology, manpower and material resources can be saved, automatic control of an external server on the vehicle-mounted unit can be achieved, the vehicles can be controlled quickly and effectively in real time, and the problem that the toll in the related technology partially runs off is solved. And control the on-board unit through the outside server, the outside server is equivalent to the supervisory organization of on-board unit, can play the effect of information verification, avoids directly controlling by oneself through on-board unit and causes the chaotic problem of on-board unit use, has improved stability, security and the rationality of on-board unit use, has strengthened user experience.

Fig. 2 is a schematic flowchart of another on-board unit control method provided in the embodiment of the present disclosure, and as shown in fig. 2, the method includes the following steps:

S210: and controlling a processor of the vehicle-mounted unit to be started based on the starting state instruction.

S3101: when the processor is turned on, a shutdown control instruction is obtained.

When the processor of the on-board unit is turned on, the controller of the on-board unit may be controlled to obtain the turn-off control command. The closing control instruction is a control instruction sent by an external server to the vehicle-mounted unit through the drive test unit, or the closing control instruction is a control instruction generated by the controller.

For example, the external server may send a shutdown control command to the drive test unit, and the drive test unit may transmit the shutdown control command to the communication device of the on-board unit. And after the communication device of the vehicle-mounted unit acquires the closing control instruction, transmitting the closing control instruction to the processor of the vehicle-mounted unit, transmitting the closing control instruction to the controller of the vehicle-mounted unit by the processor, and acquiring the closing control instruction sent by the external server by the controller of the vehicle-mounted unit.

Illustratively, the shutdown control command may be generated by the controller itself. For example, when the processor is turned on, the controller of the in-vehicle unit may determine the running behavior of the vehicle, and when it is determined that there is an abnormal running behavior of the vehicle, the controller may generate the turn-off control instruction by itself.

S3102: and controlling the use state of the on-board unit to be adjusted from the normal use state to the abnormal use state through the controller of the on-board unit based on the closing control instruction.

For example, the controller of the in-vehicle unit may control the use state of the in-vehicle unit to be adjusted from the normal use state to the abnormal use disabled state based on the shutdown control instruction.

According to the technical scheme provided by the embodiment of the disclosure, the closing control instruction can be sent to the vehicle-mounted unit through the external server, and the closing control instruction can also be generated by the controller of the vehicle-mounted unit. Various ways for obtaining the closing control instruction are provided, and the diversity of the vehicle-mounted unit control method can be improved. And adjusting the use state of the on-board unit to a normal use disabled state based on the closing control instruction. When the use state of the vehicle-mounted unit is adjusted from the normal use state to the abnormal use state, the external server can conveniently and automatically check the vehicle, so that manpower and material resources can be saved, and the vehicle can be quickly and effectively controlled in real time. The vehicle-mounted unit is controlled through the external server, the external server is equivalent to a monitoring mechanism of the vehicle-mounted unit, an information checking effect can be achieved, the problem that the vehicle-mounted unit is disordered in use due to the fact that the vehicle-mounted unit is directly controlled by the vehicle-mounted unit is avoided, the use stability, the use safety and the use rationality of the vehicle-mounted unit are improved, and user experience is enhanced.

In some embodiments, the onboard unit control method, for example, further includes:

when the abnormal driving behavior of the vehicle is determined, the control processor reports the vehicle data of the abnormal driving behavior to the external server through the drive test unit, so that the external server verifies the vehicle data of the abnormal driving behavior, and sends a closing control instruction to the vehicle-mounted unit after the verification is passed.

The abnormal driving behavior of the vehicle is different from the normal driving behavior, for example, the vehicle owner drives the vehicle in an overspeed manner to break through the vehicle in order to achieve the purpose of paying less or not paying high-speed toll, so that the vehicle speed is too high to identify the OBU, and further normal fee deduction cannot be performed. Or different OBUs are used alternately to achieve the purpose of paying less or not paying high-speed toll, so that overtime payment of the OBUs can be realized. For example, when the processor of the on-board unit determines that the vehicle has abnormal driving behavior, the processor may report the abnormal driving behavior vehicle data to the external server through the drive test unit. After the external server obtains the abnormal driving vehicle data, the abnormal driving behavior vehicle data can be verified, the abnormal driving behavior of the vehicle is further judged through the external server, the verification is passed when the abnormal driving behavior of the vehicle is determined, and a closing control command is sent to the vehicle-mounted unit after the verification is passed.

According to the technical scheme provided by the embodiment of the disclosure, the abnormal driving behavior of the vehicle can be judged through the vehicle-mounted unit, when the abnormal driving behavior of the vehicle is determined, the vehicle-mounted unit reports the vehicle data of the abnormal driving behavior to the external server, the vehicle data of the abnormal driving behavior is verified through the external server, and a closing control instruction is sent to the vehicle-mounted unit after the abnormal driving behavior is verified, so that the abnormal driving behavior of the vehicle can be further judged through the external server, the accuracy of the external server in controlling the vehicle-mounted unit is improved, the influence of the external server on the normal use of the vehicle-mounted unit in the vehicle due to misjudgment or misoperation is avoided, the influence on a user is reduced, and the user experience can be enhanced.

In some embodiments, step S3101: when the processor is turned on, after the shutdown control instruction is obtained, for example, the method includes:

storing the information data included in the closing control command.

The closing control command comprises a door frame number and position information data of a drive test unit for transmitting the closing control command, acquisition time information data of the closing control command, execution time information data of the closing control command and execution place information data of the closing control command.

According to the technical scheme provided by the embodiment of the disclosure, after the closing control instruction is acquired, the information data included in the closing control instruction can be stored, for example, the information data can be stored in the memory of the vehicle-mounted unit, so that the information data controlled by the vehicle-mounted unit is stored, that is, the history information of the external server controlling the vehicle-mounted unit is reserved. If the information inquiry requirement exists in the later period, the detailed information of the vehicle-mounted unit controlled each time can be inquired at any time through the information data stored in the vehicle-mounted unit. Therefore, the historical information of the vehicle-mounted unit controlled by the external server can be conveniently inquired, the external server is restrained, traces of the external server for controlling the vehicle-mounted unit are reserved, and the influence on user experience caused by random operation of the external server on the vehicle-mounted unit is avoided.

In some embodiments, the on-board unit control method further includes, for example:

and when the use state of the vehicle-mounted unit is a normal use disabled state, controlling the vehicle-mounted unit to stop working, or controlling the vehicle-mounted unit not to identify the ETC card meeting the preset condition, so that the vehicle-mounted unit cannot work normally. For example, a particular ETC card may not function properly on an OBU. The preset condition may be set according to a requirement of an actual on-board unit control method, for example, which is not limited in the present disclosure.

In some embodiments, the external server includes a first server and a second server. The processor comprises an active control module and a passive control module. Fig. 3 is a schematic flowchart of another vehicle-mounted unit control method provided in the embodiment of the present disclosure, and as shown in fig. 3, the method includes the following steps:

S120: and judging the signal source of the opening state instruction.

Since the first server may send the on-state instruction to the on-board unit, the second server may also send the on-state instruction to the on-board unit. And the opening state instructions of different signal sources correspondingly control the opening of different control modules in the processor. For example, an authentication module is arranged in the processor, and the authentication module can judge the signal source of the start state instruction after acquiring the start state instruction sent by the external server to the vehicle-mounted unit through the drive test unit.

S2101: and controlling the active control module to be started when the signal source of the starting state instruction is the first server, or controlling the passive control module to be started when the signal source of the starting state instruction is the second server.

Because the opening state instructions of different signal sources correspondingly control the opening of different control modules in the processor, when the signal source of the opening state instruction is the first server, the active control module can be controlled to be opened. When the signal source of the start state instruction is the second server, the passive control module can be controlled to start. That is, the start state instruction sent by the first server is only used for starting the active control module in the processor, and the start state instruction sent by the second server is only used for starting the passive control module in the processor.

S2102: and when the active control module and the passive control module are both started, determining that the processor is started.

S3101: when the processor is turned on, a turn-off control instruction is obtained.

According to the technical scheme provided by the embodiment of the disclosure, the active control module and the passive control module are arranged in the processor, the active control module can only receive the starting state instruction sent by the first server, and the passive control module can only receive the starting state instruction sent by the second server. That is, the first server can only control the active control module to be turned on, and the second server can only control the passive control module to be turned on. Therefore, the opening of the processor of the vehicle-mounted unit can be controlled through the two different servers, so that the vehicle-mounted unit can be controlled only after the first server and the second server send opening state instructions, and the normal use state is adjusted to be the state which cannot be used normally. If one of the first server and the second server does not send the opening state instruction, the vehicle-mounted unit cannot be controlled by the server. The first server and the second server are used for restricting the control of the vehicle-mounted unit together, abuse of the control function of the vehicle-mounted unit by any one of the first server and the second server is avoided, the opening state instructions are issued to the vehicle-mounted unit through the two different servers respectively, and the vehicle-mounted unit can be controlled only when the two servers agree to control the vehicle-mounted unit. The effect of carrying out hierarchical control to the vehicle-mounted unit not only can be realized, validity and rationality that external server carries out control to the vehicle-mounted unit can also be realized, avoid carrying out arbitrary deduction of toll through control vehicle-mounted unit, user's information and property safety have been ensured.

In some embodiments, the time interval between the on state instruction sent by the first server and the on state instruction sent by the second server is greater than zero.

When the active control module and the passive control module are both started, the processor is determined to be started, and at the moment, the vehicle-mounted unit can obtain a closing control instruction, so that the control of the external server on the vehicle-mounted unit is realized. According to the technical scheme provided by the embodiment of the disclosure, when the time interval between the opening state instruction sent by the first server and the opening state instruction sent by the second server is greater than zero, the vehicle-mounted unit can be controlled in a grading manner through two different servers, for example, the vehicle-mounted unit can be controlled through two servers in different grades, and the two servers can be in a relationship of upper and lower grades, so that the effectiveness and the rationality of the control of the vehicle-mounted unit are realized. The time-sharing control of the vehicle-mounted unit can be realized, so that the flexibility of the control of the external server on the vehicle-mounted unit can be improved.

In some embodiments, step S2101: when the signal source of the start state instruction is the first server, the active control module is controlled to start, or when the signal source of the start state instruction is the second server, the passive control module is controlled to start, for example, the method includes:

performing a cycling step, the cycling step comprising: the method comprises the steps of obtaining an opening state instruction sent by an external server to a vehicle-mounted unit through a road test unit, judging a signal source of the opening state instruction, controlling an active control module to be opened when the signal source of the opening state instruction is a first server, and controlling a passive control module to be opened when the signal source of the opening state instruction is a second server.

And ending the execution cycle step until the active control module and the passive control module are both started.

Specifically, when the time interval between the start state instruction sent by the first server and the start state instruction sent by the second server is greater than zero, the on-board unit may, for example, obtain the start state instruction sent by the external server to the on-board unit through the drive test unit, determine a signal source of the start state instruction, and control the active control module to start when the signal source of the start state instruction is the first server. After the preset time interval, the vehicle-mounted unit can acquire an opening state instruction sent to the vehicle-mounted unit by the external server through the drive test unit, judge a signal source of the opening state instruction, and control the passive control module to be opened when the signal source of the opening state instruction is the second server, so that the active control module and the passive control module are both opened. Or, when the time interval between the start state instruction sent by the first server and the start state instruction sent by the second server is greater than zero, the on-board unit may, for example, obtain the start state instruction sent by the external server to the on-board unit through the drive test unit, determine a signal source of the start state instruction, and control the passive control module to start when the signal source of the start state instruction is the second server. After the preset time interval, the vehicle-mounted unit can acquire an opening state instruction sent to the vehicle-mounted unit by the external server through the drive test unit, a signal source of the opening state instruction is judged, and when the signal source of the opening state instruction is the first server, the active control module is controlled to be opened, so that the active control module and the passive control module are both opened. Execution of the loop step may be terminated when both the active control module and the passive control module are turned on.

According to the technical scheme provided by the embodiment of the disclosure, the starting state instruction sent by the external server is obtained through circulation, the signal source of the starting state instruction is judged, the active control module is controlled to be started or the passive control module is controlled to be started according to the signal source of the starting state instruction, and the circulation step is finished after the active control module and the passive control module are both started, so that the classification and time-sharing control of the vehicle-mounted unit can be realized, and the method is simple and easy to realize.

In some embodiments, the signal source is an on state instruction of the first server for turning off when the using state of the on-board unit is the abnormal using state, and/or the signal source is an on state instruction of the second server for turning off when the using state of the on-board unit is the abnormal using state.

Specifically, the signal source is an on-state instruction of the first server, that is, the on-state instruction sent by the first server, and is used for stopping when the use state of the vehicle-mounted unit is the abnormal use state. The active control module is used for controlling the on-board unit to be in a normal use state, and the on-board unit is used for sending an on-board command to the first server. Therefore, the on-state instruction sent by the first server has timeliness, namely, when the controller of the vehicle-mounted unit controls the use state of the vehicle-mounted unit to be adjusted from the normal use state to the abnormal use state based on the closing control instruction, the on-state instruction sent by the first server is controlled to be invalid. The first server sets a time-based constraint on the control authority of the vehicle-mounted unit, so that the first server cannot control the vehicle-mounted unit indefinitely. Therefore, the requirements of different vehicle-mounted unit control methods can be met, and the diversity of the vehicle-mounted unit control methods is improved.

Specifically, the signal source is an on-state instruction of the second server, namely, the on-state instruction sent by the second server, and is used for stopping when the use state of the on-board unit is a normal use disabled state. Namely, when the use state of the vehicle-mounted unit is adjusted from the normal use state to the abnormal use state, the opening state instruction sent by the second server is invalid, and the opening state instruction sent by the second server is used for opening the passive control module, so that the passive control module is closed after the opening state instruction sent by the second server is invalid. Therefore, the on-state instruction sent by the second server has timeliness, namely, when the controller of the vehicle-mounted unit controls the use state of the vehicle-mounted unit to be adjusted from the normal use state to the abnormal use state based on the closing control instruction, the on-state instruction sent by the second server is controlled to be invalid. The second server sets a time-based constraint on the control authority of the on-board unit, so that the second server cannot control the on-board unit indefinitely. Therefore, the requirements of different vehicle-mounted unit control methods can be met, and the diversity of the vehicle-mounted unit control methods is improved.

According to the technical scheme, the signal source is the starting state instruction of the first server and used for stopping when the using state of the vehicle-mounted unit is the abnormal using state, and/or the signal source is the starting state instruction of the second server and used for stopping when the using state of the vehicle-mounted unit is the abnormal using state. Therefore, the on-state instruction sent by the first server and/or the second server has timeliness, namely, when the controller of the vehicle-mounted unit controls the use state of the vehicle-mounted unit to be adjusted from the normal use state to the abnormal use state based on the closing control instruction, the on-state instruction sent by the first server and/or the second server is controlled to be invalid. The first server and/or the second server set a time-based constraint on the control authority of the vehicle-mounted unit, so that the second server cannot control the vehicle-mounted unit indefinitely. Therefore, the requirements of different vehicle-mounted unit control methods can be met, and the diversity of the vehicle-mounted unit control methods is improved.

In some embodiments, for example, the signal source may be an on-state command and an off-control command of the first server at the same time, and/or the signal source may be an on-state command and an off-control command of the second server at the same time.

According to the technical scheme, the signal source is the opening state instruction and the closing control instruction of the first server, and/or the signal source is the opening state instruction and the closing control instruction of the second server. Therefore, the requirements of different vehicle-mounted unit control methods can be met, the diversity of the vehicle-mounted unit control methods is improved, and the method is simple and easy to implement.

For example, when the signal source is an on-state command of the first server and is used for being cut off when the use state of the on-board unit is the abnormal use state, and/or the signal source is an on-state command of the second server and is used for being cut off when the use state of the on-board unit is the abnormal use state, the time interval between the acquisition of the on-state command and the acquisition of the off control command of the first server is set to be zero, and/or the time interval between the acquisition of the on-state command and the acquisition of the off control command of the second server is set to be zero. Therefore, the control time of the first server and/or the second server to the vehicle-mounted unit is further shortened, the first server and/or the second server are prevented from controlling the vehicle-mounted unit for a long time, the information and property safety of a user is guaranteed, and the user experience is improved.

In some embodiments, step S310: when the processor is started, after the controller of the on-board unit controls the use state of the on-board unit to be adjusted from the normal use state to the abnormal use state, for example, the method includes:

and acquiring an opening control instruction and a closing state instruction sent to the vehicle-mounted unit by the external server through the drive test unit.

And closing the processor based on the closing state instruction, and controlling the use state of the vehicle-mounted unit to be adjusted from the abnormal use state to the normal use state based on the opening control instruction.

Specifically, when the use state of the on-board unit is the abnormal use state, the on-board unit can be controlled to obtain the opening control instruction and the closing state instruction sent by the external server to the on-board unit through the drive test unit. For example, the controller of the on-board unit may be controlled to acquire the opening control command. The starting control instruction is a control instruction sent by an external server to the vehicle-mounted unit through the drive test unit, or the starting control instruction is a control instruction generated by the controller.

For example, the start control command may be sent to the drive test unit through the external server, and then transmitted to the communication device of the on-board unit by the drive test unit. And after the communication device of the vehicle-mounted unit acquires the opening control instruction, transmitting the opening control instruction to a processor of the vehicle-mounted unit, transmitting the opening control instruction to a controller of the vehicle-mounted unit by the processor, and acquiring the opening control instruction transmitted by the external server by the controller of the vehicle-mounted unit.

For example, the start control command may be generated by the controller itself. For example, when the usage state of the on-board unit is the abnormal usage state, the controller of the on-board unit may determine whether or not the usage state of the on-board unit can be restored to the normal usage state, and for example, when the duration of the abnormal usage state of the on-board unit is equal to or longer than a preset time threshold, the usage state of the on-board unit can be restored to the normal usage state, and the controller may generate the start control command by itself. The controller of the onboard unit sets the judgment condition for whether the use state of the onboard unit can be recovered to the normal use state according to the design requirements of the actual onboard unit control method, which is not limited by the present disclosure.

For example, the processor of the on-board unit may be controlled to acquire a close state instruction that the external server transmits to the on-board unit through the drive test unit.

Since the external server is in communication connection with the drive test unit, the drive test unit can receive the shutdown state instruction sent by the external server. The drive test unit is in communication connection with the communication device of the vehicle-mounted unit, so that the closing state instruction sent by the external server through the drive test unit can be acquired through the communication device. For example, when the use state of the vehicle-mounted unit is a normal use disabled state and the external server detects that the vehicle has no abnormal driving behavior, the external server may send a shutdown state instruction to the drive test unit, and the drive test unit transmits the shutdown state instruction to the vehicle-mounted unit. Alternatively, for example, when the external server needs to stop controlling the in-vehicle unit, the shutdown state command may be transmitted to the in-vehicle unit by the drive test unit.

The on-board unit shutdown processor can be controlled based on the shutdown state instruction, and the use state of the on-board unit is controlled to be adjusted from the abnormal use state to the normal use state based on the startup control instruction.

According to the technical scheme provided by the embodiment of the disclosure, the starting control instruction can be sent to the vehicle-mounted unit through the external server, and the starting control instruction can also be automatically generated through the controller of the vehicle-mounted unit. A plurality of ways for acquiring the starting control instruction are provided, and then the diversity of the control method of the vehicle-mounted unit can be improved. And based on the opening control instruction and a closing state instruction sent by the external server to the vehicle-mounted unit through the drive test unit, closing the processor and adjusting the use state of the vehicle-mounted unit to a normal use state. The vehicle is automatically controlled by the external server conveniently, manpower and material resources can be saved, the vehicle can be controlled quickly and effectively in real time, and the method is simple and easy to implement.

Corresponding to the onboard unit control method provided by the embodiment of the present disclosure, the embodiment of the present disclosure also provides an onboard unit control system, fig. 4 is a block diagram of a structure of the onboard unit control system provided by the embodiment of the present disclosure, and as shown in fig. 4, the onboard unit control system includes an onboard unit 1. The on-board unit 1 includes a processor 11, a controller 12, and a communication device 13. The communication device 13 is used for communication connection with the road side units 2 distributed on different lanes. The communication device 13 is used for acquiring an on-state instruction sent by the external server 3 to the on-board unit 1 through the drive test unit 2. The processor 11 is electrically connected to the communication device 13. The processor 11 is configured to control the processor 11 to be turned on based on the on-state instruction. The controller 12 is electrically connected to the processor 11. The controller 12 is configured to control the usage state of the on-board unit 1 to be adjusted from a normal usage state to an abnormal usage state when the processor 11 is turned on.

Therefore, according to the technical scheme provided by the embodiment of the disclosure, the communication device can acquire the opening state instruction sent by the external server to the vehicle-mounted unit through the drive test unit. Therefore, the communication connection between the vehicle-mounted unit and the external server can be realized, so that the vehicle-mounted unit can receive the opening state instruction sent by the external server to the vehicle-mounted unit. The processor of the on-board unit may control the processor to turn on based on the on-state instruction. Therefore, the external server can control the opening state of the processor of the vehicle-mounted unit through the opening state instruction, and the aim of controlling the vehicle-mounted unit by the external server is further fulfilled. When the processor is started, the controller of the vehicle-mounted unit can control the use state of the vehicle-mounted unit to be adjusted from the normal use state to the abnormal use state. The external server can only control the processor of the on-board unit to be started, so that the controller of the on-board unit cannot be directly controlled, and the controller of the on-board unit is used for controlling the use state of the on-board unit. Therefore, the normal use of the vehicle-mounted unit is not influenced when the processor is not started, namely the vehicle-mounted unit can be normally used when the external server does not control the vehicle-mounted unit, and the vehicle-mounted unit can be controlled not to be normally used when the external server controls the vehicle-mounted unit. Therefore, the vehicles with abnormal fee deduction are not required to be intercepted in a manual inspection mode in the related technology, manpower and material resources can be saved, automatic control of an external server on the vehicle-mounted unit can be achieved, the vehicles can be controlled quickly and effectively in real time, and the problem that the toll is partially lost in the related technology is solved. And control the on-board unit through the outside server, the outside server is equivalent to the supervisory organization of on-board unit, can play the effect of information verification, avoids directly controlling by oneself through on-board unit and causes the chaotic problem of on-board unit use, has improved stability, security and the rationality of on-board unit use, has strengthened user experience.

In some embodiments, as shown in FIG. 4, the processor 11 includes a passive control module 14, an active control module 15, and an authentication module 16. The communication device 13 is electrically connected to the passive control module 14 via an authentication module 16. The passive control module 14 is electrically connected to the controller 12 through the active control module 15. The authentication module 16 is configured to determine a signal source of the open state command when the external server 3 includes the first server 31 and the second server 32. The active control module 15 is configured to control the active control module 15 to start when the signal source based on the start state instruction is the first server 31. The passive control module 14 is configured to control the passive control module 14 to start when the signal source based on the start state instruction is the second server 32.

According to the technical scheme provided by the embodiment of the disclosure, the active control module, the passive control module and the authentication module are arranged in the processor, the active control module can only receive the starting state instruction sent by the first server, and the passive control module can only receive the starting state instruction sent by the second server. That is, the first server can only control the active control module to be turned on, and the second server can only control the passive control module to be turned on. Therefore, the opening of the processor of the vehicle-mounted unit can be controlled through the two different servers, so that the vehicle-mounted unit can be controlled only after the first server and the second server send opening state instructions, and the normal use state is adjusted to be the state incapable of being used normally. If one of the first server and the second server does not send the opening state instruction, the vehicle-mounted unit cannot be controlled by the server. The first server and the second server are used for restricting the control of the vehicle-mounted unit together, the abuse of the control function of the vehicle-mounted unit by any one of the first server and the second server is avoided, the opening state instructions are respectively issued to the vehicle-mounted unit through the two different servers, and the control of the vehicle-mounted unit can be realized only when the two servers agree to control the vehicle-mounted unit. The effect of carrying out hierarchical control to the vehicle-mounted unit not only can be realized, validity and rationality that external server carries out control to the vehicle-mounted unit can also be realized, avoid carrying out arbitrary deduction of toll through control vehicle-mounted unit, user's information and property safety have been ensured.

Optionally, the communication device 13 is electrically connected to the passive control module 14 via the authentication module 16. The passive control module 14 is electrically connected to the controller 12 through the active control module 15. The communication device 13 is communicatively connected to the external server 3. Thus, the external server 3 transmits the status command to the active control module 15 through the passive control module 14. The controller 12 reports vehicle-related information data to the external server 3 through the passive control module 14 via the active control module 15.

In some embodiments, the first server and the second server may be communicatively connected, for example, the first server may be a superior control mechanism of the second server, and the second server is used for directly issuing the shutdown control command to the on-board unit to realize the control of the on-board unit, but the second server must pass the permission of the first server before issuing the shutdown control command. Alternatively, for example, the second server may be a superior control mechanism of the first server, and the first server is a mechanism for directly issuing a closing control instruction or an opening control instruction to the on-board unit, that is, the first server is a mechanism for issuing a control instruction to the on-board unit, but the first server must pass permission of the second server before issuing the closing control instruction or the opening control instruction. The constraint relationship between the first server and the second server is not limited by this disclosure.

In some embodiments, as shown in FIG. 4, the on-board unit control system further includes, for example, a card reader 17, a power source 18, and a memory 19. The card reader 17 is used to read information data in an ETC card inserted into the on-board unit. The power supply 18 provides a source of electrical power for the on-board unit 1. The memory 19 is electrically connected to the passive control module 14, the active control module 15 and the authentication module 16, respectively, for storing control-related information data. For example, the memory 19 can be used for closing information data comprised by the control instruction. The closing control command comprises a door frame number and position information data of a drive test unit for transmitting the closing control command, acquisition time information data of the closing control command, execution time information data of the closing control command and execution place information data of the closing control command.

The vehicle-mounted unit control system disclosed in the above embodiments can execute the vehicle-mounted unit control method disclosed in each of the above embodiments, has the same or corresponding beneficial effects, and is not described herein again to avoid repetition.

For example, with respect to the structure of the on-board unit control system provided by the embodiment of the present disclosure, a plurality of different types of control modes may be set in the on-board unit by using the on-board unit control method provided by the embodiment of the present disclosure, for example, the control modes of the on-board unit include a normal mode, an active control mode, a passive control mode, a to-be-controlled mode, and an abnormal mode. The technical scheme provided by the embodiment of the disclosure includes and is not limited to the control modes of the vehicle-mounted units. Fig. 5 is a schematic diagram of mode instruction switching provided by an embodiment of the present disclosure, and a control mode of an on-board unit is exemplarily described below with reference to fig. 5, where the control mode of the on-board unit is executed by an on-board unit control system, and the structure of the on-board unit control system may refer to the structure shown in fig. 4.

The five control modes of the on-board unit, i.e., the normal mode, the active control mode, the passive control mode, the to-be-controlled mode, and the abnormal mode, will be described in detail below with reference to fig. 4 and 5. The external server is used for sending different types of state instructions to the vehicle-mounted unit, and the state instructions are used for controlling the opening or closing of the processor, namely controlling the opening or closing of the active control module and the passive control module. The status instruction is used for realizing switching among different control modes. And the external server or the controller of the on-board unit may transmit different types of control instructions for controlling the use states of the on-board unit including the abnormal use state and the normal use state.

Normal mode

The normal mode is set such that the onboard unit is in a normal use state, in which the processor is in an off state, and the onboard unit cannot receive an off control command.

Active control mode

The active control mode is set to be a processor opening state instruction sent to the on-board unit by the external server through the drive test unit when the on-board unit is in a normal use state, the processor of the on-board unit controls the processor of the on-board unit to be opened based on the opening state instruction, and when the processor is opened, the controller of the on-board unit can be controlled to obtain a closing control instruction. The controller of the on-board unit may control the use state of the on-board unit to be adjusted from the normal use state to the abnormal use disabled state based on the shutdown control instruction. When the using state of the on-board unit is a normal use disabled state, the control mode of the on-board unit is an abnormal mode, and when the abnormal control mode is ended, the external processor simultaneously sends an on control instruction and an off state instruction to the on-board unit, and the processor of the on-board unit switches the control mode of the on-board unit to the normal mode based on the off state instruction. The controller of the on-board unit controls the use state of the on-board unit to be adjusted from the abnormal use state to the normal use state based on the opening control instruction.

And the closing state instruction and the opening state instruction are issued to the vehicle-mounted unit by the external server through the drive test unit. The starting control instruction is a control instruction sent by an external server to the processor through the drive test unit, or the starting control instruction is a control instruction sent by the controller. The closing control instruction is a control instruction sent by the external server to the vehicle-mounted unit through the road test unit, or the closing control instruction is a control instruction generated by the controller.

Mode to be controlled

The mode to be controlled is set to be, for example, that the second server may be a superior control mechanism of the first server, and the first server is used for directly issuing the closing control instruction or the opening control instruction to the on-board unit, that is, the first server is a mechanism for issuing the control instruction to the on-board unit, but the first server must pass permission of the second server before issuing the closing control instruction or the opening control instruction. The starting state instruction sent by the first server is an active control module starting state instruction which is only used for starting an active control module in the processor. The opening state instruction sent by the second server is a passive control module opening state instruction which is only used for opening a passive control module in the processor. The mode to be controlled includes: when the using state of the vehicle-mounted unit is a normal using state, the vehicle-mounted unit can acquire an opening state instruction sent to the vehicle-mounted unit by the external server through the drive test unit, judge a signal source of the opening state instruction, and control the active control module to be opened when the signal source of the opening state instruction is the first server. At this time, the control mode of the vehicle-mounted unit is a to-be-controlled mode, wherein the active control module is started, the passive control module is not started, and the controller of the vehicle-mounted unit does not receive a control instruction. In the standby control mode, when a passive module opening state instruction sent by the second server is received, after the signal source of the opening state instruction is judged, the passive control module can be controlled to be opened according to the passive module opening state instruction, so that the active control module and the passive control module are both opened, and the control mode of the vehicle-mounted unit is switched from the standby control mode to the active control mode and operates according to the operation mode of the active control mode.

Passive control mode

For example, the first server may be a higher-level control mechanism of the second server, and the second server is used for directly issuing a close control command or an open control command to the on-board unit, that is, the second server is a mechanism for issuing a control command to the on-board unit, but the second server must pass permission of the first server before issuing the close control command or the open control command. The starting state instruction sent by the first server is an active control module starting state instruction, and the active control module starting state instruction is only used for starting an active control module in the processor. The opening state instruction sent by the second server is a passive control module opening state instruction which is only used for opening a passive control module in the processor.

The passive control mode includes: when the use state of the vehicle-mounted unit is the normal use state, the vehicle-mounted unit can acquire an opening state instruction sent to the vehicle-mounted unit by the external server through the drive test unit, judge the signal source of the opening state instruction, and control the passive control module to be opened when the signal source of the opening state instruction is the second server. At this time, the control mode of the on-board unit is a passive control mode, wherein the passive control module is started, the active control module is not started, and the controller of the on-board unit does not receive a control instruction. In the passive control mode, when a temporary starting state instruction of the active control module sent by the first server is received, after the signal source of the starting state instruction is judged, the active control module can be controlled to be started according to the temporary starting state instruction of the active control module, so that the active control module and the passive control module are both started. The active control module temporarily starts the state command to be used for stopping when the using state of the vehicle-mounted unit is a normal using disabled state. And a closing control command is sent to the on-board unit by the first server. In the passive control mode, the active module opening state instruction sent by the first server is a one-time instruction, and before the first server executes the closing control instruction every time, the active control module temporary opening state instruction needs to be sent first, so that the closing control instruction can be obtained after the active control module and the passive control module are both opened.

Non-normal mode

The abnormal mode is set such that the usage state of the on-board unit is a normal usage disabled state, and the processor is in an on state. When the abnormal mode is finished, the external processor simultaneously sends an opening control instruction and a closing state instruction to the vehicle-mounted unit, and the processor of the vehicle-mounted unit switches the control mode of the vehicle-mounted unit to the normal mode based on the closing state instruction. The controller of the on-board unit controls the use state of the on-board unit to be adjusted from the abnormal use state to the normal use state based on the opening control instruction. And the closing state instruction is issued to the vehicle-mounted unit by the external server through the drive test unit. The starting control instruction is a control instruction sent by an external server to the processor through the drive test unit, or the starting control instruction is a control instruction sent by the controller.

Exemplarily, the active control mode of the on-board unit is explained as follows: the vehicle-mounted unit of the vehicle-mounted unit is controlled to be in communication connection with the drive test unit, and when the opening state instruction of the processor is obtained, the control mode of the vehicle-mounted unit is determined to be in the active control mode. When the control mode of the vehicle-mounted unit is determined to be in the active control mode, and after the communication device of the vehicle-mounted unit is in communication connection with the drive test unit, the fields required by the active control mode are stored in the memory, so that the fields required by the active control mode can be called from the memory by the processor of the vehicle-mounted unit conveniently. And the active control module of the processor analyzes the abnormal driving behavior of the vehicle on the fields in the storage unit. When the active control module of the processor determines that the vehicle has abnormal driving behaviors, when the vehicle enters high speed again, the active control module of the processor transmits the vehicle data of the abnormal driving behaviors to the passive control module, the vehicle data are transmitted into the external server by the passive control module, the external server verifies the vehicle data of the abnormal driving behaviors, and after the verification is passed, a closing control instruction is sent to the vehicle-mounted unit, the use state of the vehicle unit is adjusted from a normal use state to a non-normal use state, and for example, the vehicle-mounted unit can not work normally.

Illustratively, the passive control mode of the on-board unit is exemplified: the vehicle-mounted unit of the vehicle-mounted unit is controlled to be in communication connection with the drive test unit, and when the opening state instruction of the passive module is obtained, the control mode of the vehicle-mounted unit is determined to be in the passive control mode. And after the passive control mode is started, starting the passive control module. And then the passive control module can receive the opening state instruction of the active control module, transmit the opening state instruction of the active control module to the active control module and open the active control module. After the active control module is started, the external server may send a closing control instruction to adjust the use state of the vehicle unit from a normal use state to a non-normal use state, for example, so that the vehicle-mounted unit cannot work normally. And simultaneously storing the information data included in the closing control instruction in the passive control mode into a memory for data backup. The closing control command comprises a door frame number and position information data of a drive test unit for transmitting the closing control command, acquisition time information data of the closing control command, execution time information data of the closing control command and execution place information data of the closing control command.

For example, the passive control module can be applied to the following two scenarios:

in a first scenario, at a drive test unit of a high-speed entrance, a vehicle-mounted unit device is in a passive control mode, the vehicle-mounted unit receives an active control module opening state instruction and a closing control instruction sent by an external server, and the use state of the vehicle unit is adjusted from a normal use state to a non-normal use state according to a control method of the passive control mode, for example, the vehicle-mounted unit cannot normally work. This prevents the vehicle from being allowed to drive into high speeds.

And in a second scenario, in the process that the vehicle runs on the expressway, the vehicle-mounted unit equipment is in a passive control mode, when the external server determines that the vehicle has abnormal running behaviors, the external server sends a passive control module opening state instruction and a passive control module closing control instruction through any road test unit arranged on the road, so that the vehicle-mounted unit is in the passive control mode, the use state of the vehicle unit is adjusted from a normal use state to a non-normal use state according to a control method of the passive control mode, and for example, the vehicle-mounted unit can not normally work.

Illustratively, switching between control modes of different on-board units is exemplified as follows:

in the first situation, when the control mode of the vehicle-mounted unit is in the normal mode, the second server sends out a passive control module opening state instruction, and the control mode of the vehicle-mounted unit is adjusted to be the passive control mode. After entering the passive control mode, the first server has the right to start the active control module, and the control mode of the vehicle-mounted unit is adjusted to the active control mode.

And secondly, when the control mode of the vehicle-mounted unit is in the normal mode, the vehicle has abnormal running behaviors in the past and the time span is long, namely when the abnormal running behaviors of the vehicle are found in the past long time period, the second server sends out an instruction for starting the passive control mode, so that the vehicle is in the state that the passive control module is started in the passive control mode, and the passive control module is activated. When the first server determines that the vehicle has abnormal driving behaviors, the first server transmits a temporary state opening command and a temporary state closing command of the active control module, and controls the state of the vehicle-mounted unit to be in a normal use disabled state while activating the active control module.

And in the third situation, after the active control module is activated by the active control module starting state instruction sent by the first server, the control mode of the vehicle-mounted unit is in a to-be-controlled mode. When the vehicle has abnormal running behaviors in the past and the time span is short, namely the vehicle is found to have the abnormal running behaviors in a short period of time in the past, the second server sends a passive control module opening state instruction to activate the passive control module, and the vehicle-mounted unit can directly receive a closing control instruction.

According to the technical scheme, the vehicle with abnormal fee deduction is intercepted without adopting a manual inspection mode in the related technology, manpower and material resources can be saved, automatic control of an external server on a vehicle-mounted unit can be achieved, the vehicle can be controlled rapidly and effectively in real time, and the problem that the toll part runs off in the related technology is solved. And control the on-board unit through the outside server, the outside server is equivalent to the supervisory organization of on-board unit, can play the effect of information verification, avoids directly controlling by oneself through on-board unit and causes the chaotic problem of on-board unit use, has improved stability, security and the rationality of on-board unit use, has strengthened user experience. Meanwhile, various types of vehicle-mounted unit control modes can be set in the vehicle-mounted unit according to the technical scheme provided by the embodiment of the disclosure, so that the design diversity of the vehicle-mounted unit is improved, and the design requirements of different vehicle-mounted units are met.
