Fig. 1 is a schematic diagram illustrating an application scenario of a method and a system for supervising functional units in an intelligent traffic management system, which are applicable to an embodiment of the present invention. The intelligent traffic management system is a comprehensive transportation system which effectively and comprehensively utilizes advanced information technology, data communication technology, sensor technology, electronic control technology, computer technology and the like to strengthen the relation among vehicles, roads and users, thereby ensuring safety, improving efficiency, improving environment and saving energy. The intelligent traffic management system also includes a plurality of subsystems such as a vehicle control system, an electronic toll collection system, ETC. A main application scenario ETC of the embodiment of the present invention will be described below with reference to fig. 1.

As shown in fig. 1, the ETC system 100 may include a Road Side Unit (RSU) 110, an On Board Unit (OBU) 120, and a backend management end 130. The RSU is usually disposed on the ETC lane (or on a gantry in some scenarios) and used as a roadside base station, and in some application scenarios, the RSU may be composed of a read-write antenna and a radio frequency controller. The read-write antenna is a microwave transceiver module and can be responsible for sending, receiving, modulating, demodulating, encoding, decoding, encrypting, decrypting and the like of signals and data. The radio frequency controller is a module for controlling data transmission and reception and processing information transmission and reception to an upper computer.

As further shown in fig. 1, the OBU may be mounted on a vehicle windshield to record traffic information and the like for the vehicle. The OBU and the RSU generally use Dedicated Short-Range Communication (DSRC) for half-duplex Communication, and use 5.8GHz microwave band, and the Communication distance is generally 10 m. The background management terminal can perform information interaction with the RSU to receive the parameter information of the RSU transmitted by the RSU, the interaction information of the RSU and the OBU and the like so as to identify the vehicle information of the passing vehicle. The background management end can be connected with an electronic payment center, so that the purpose of paying without stopping when the vehicle passes through the expressway or the bridge toll station is achieved. The background management end can comprise a background server and the like. The background management terminal can also communicate with the user terminal to transmit the state information, the payment information and the like of the vehicle-mounted unit to the user.

In other embodiments, the ETC system 100 may further include a lane control system, which may include: lane computers, lane controllers, and other ancillary equipment (e.g., loop sensors, balustrades, traffic displays, etc.). Wherein the lane computer is a carrier of a lane application program (comprising charging software and communication software) and a central hub of lane processing. The lane controller refers to a device for processing signal conversion between a lane computer and an external device.

The inventor finds that the working states (such as radio frequency parameters, battery voltage, transaction success rate, transaction logs, anti-disassembly switch states, Bluetooth states and the like) of the existing vehicle-mounted unit are often checked by field workers on site, or when the vehicle-mounted unit and the road side unit are successfully interacted, the working states are transmitted back to a background management end through the road side unit. However, when the communication between the on-board unit and the roadside unit is abnormal, the roadside unit cannot return data related to the on-board unit, and therefore the background management end may not timely and accurately acquire the working state information of the on-board unit.

The inventor also finds that the existing road side unit can transmit the working state of the road side unit or the working state of the vehicle-mounted unit interacted with the road side unit back to the background management end in a wired mode such as an interface RS422, an interface RS232, an interface RS485 or Ethernet. However, since the rsus usually communicate with each other by a pair of multiple on-board units, problems such as link collision, large data amount, single backhaul link, redundant information, and untimely backhaul are likely to occur. Furthermore, when the roadside unit is abnormal, the roadside unit with the abnormality cannot be timely positioned, so that the roadside unit is often required to be reported by field personnel, the working efficiency is greatly influenced, and the labor cost is increased.

Aiming at the defects of the prior art, the invention provides a brand-new realizable solution. Particularly, the method for supervising the functional units in the intelligent traffic management system can communicate with the functional units through the first communication mode and communicate with the background management end through the second communication mode to transmit information related to the functional units, can integrally change a supervision system of the functional units, effectively solves the problem that the RSU is in fault or the interactive link of the OBU and the RSU is abnormal and cannot transmit information to the background management end, and therefore the effectiveness and timeliness of supervision of the functional units are improved. As will be understood by those skilled in the art from the following description, in some embodiments, the method of the present invention may further utilize the positioning module to acquire second location information related to the on-board unit, and send the second location information to the backend management terminal via the second communication method, so as to assist in positioning the on-board unit or the roadside unit. The following detailed description of specific embodiments of the invention is provided in connection with the accompanying drawings.

Fig. 2 is a flow chart generally illustrating a method for supervising functional units in an intelligent traffic management system according to the present invention. As shown in fig. 2, method 200 may include: in step 210, the functional unit is communicated via a first communication means to transmit information related to the functional unit. The communication with the functional unit via the first communication means may be direct or indirect. In some embodiments, the first communication mode may be a dedicated short-range communication DSRC mode, and may use a 5.8GHz microwave band.

According to one embodiment of the invention, the functional unit may comprise an on-board unit and/or a roadside unit, and communicating with the functional unit via the first communication means to transmit information related to the functional unit may comprise any one or more of: communicating directly with the on-board unit to transmit first information related to the on-board unit; communicating directly with the rsu to transmit second information related to the rsu; and communicating with the road side unit via the on-board unit to transmit second information related to the road side unit. The communication with the rsu via the on-board unit may be indirectly communication with the rsu, that is, may communicate with the on-board unit via the first communication manner, so as to obtain the second information by the on-board unit, where the second information may be obtained by the on-board unit when the on-board unit interacts with the rsu.

According to another embodiment of the present invention, the first information may include at least one of: parameter configuration information for the on-board unit; status information of the on-board unit; parameter information of the on-board unit; and the interactive information of the vehicle-mounted unit and the road side unit. In some embodiments, the parameter configuration information for the vehicle-mounted unit may be information sent by the backend management end to configure the parameter of the vehicle-mounted unit. The status information of the on-board unit may include, for example, an operating voltage of the on-board unit, and the like. The parameter information of the on-board unit may include, for example, a radio frequency parameter of the on-board unit, a network card physical address (MAC ID), and the like. The interaction information of the on-board unit and the road side unit can comprise information such as transaction logs, transaction success rate and the like.

According to yet another embodiment of the present invention, the second information may include at least one of: parameter configuration information for the roadside unit; status information of the roadside unit; parameter information of the roadside unit; first location information of a roadside unit; and the interactive information of the road side unit and the vehicle-mounted unit. In some embodiments, the parameter configuration information for the roadside unit may be information for configuring a parameter of the roadside unit sent by the backend management. The state information of the roadside unit may include, for example, an operating voltage of the roadside unit, and the like. The parameter information of the rsu may include, for example, radio frequency parameters of the rsu, etc. The first location information of the rsu may include, for example, an antenna number, a station number, a lane number, etc. of the rsu. The interaction information of the road side unit and the vehicle-mounted unit can comprise transaction logs, transaction success rate and the like.

Next, in step 220, the backend management terminal may communicate with the backend management terminal via a second communication method different from the first communication method to transmit information related to the functional unit, so that the backend management terminal monitors and manages the functional unit according to the information. In some embodiments, the second communication means may be a wireless communication means different from the first communication means. In other embodiments, the second communication mode may be a mobile communication mode, such as a 3G communication mode, a 4G communication mode, a 5G communication mode, a 6G communication mode, and the like. The information related to the functional unit may include first information related to the on-board unit and/or second information related to the roadside unit, and the first information and the second information are already described above in connection with step 210 and are not described herein again.

According to yet another embodiment of the invention, method 200 may be implemented by a tachograph. According to the embodiment, the automobile data recorder can directly communicate with the vehicle-mounted unit through the first communication mode to transmit first information related to the vehicle-mounted unit, and can also directly or indirectly communicate with the road side unit to transmit second information related to the road side unit. The automobile data recorder can also communicate with the background management terminal through a second communication mode to transmit the first information and/or the second information. According to the arrangement, the automobile data recorder can be independent of the functional unit and can be used as a communication bridge for connecting the functional unit and the background management end, information cannot be transmitted to the background management end due to the fact that the functional unit is abnormal, and therefore the functional unit can be monitored more stably and more effectively.

While the method for supervising functional units in an intelligent traffic management system according to the present invention is described above with reference to fig. 2, it will be understood by those skilled in the art that the above description is exemplary and not limiting, for example, the method 200 may not be limited to be implemented by a tachograph, but may be implemented by other devices or apparatuses as needed, such as a central control device, a navigation device, a steering wheel, a dashboard, etc. For example, the method of the present invention is not limited to transmitting only the first information or the second information via the second communication means, and in other embodiments, for example, the position information of the functional unit or the like may be transmitted via the second communication means. For ease of understanding, the following exemplary description is provided in connection with FIG. 3 a.

Fig. 3a is a flow chart illustrating a method for supervising functional units in an intelligent traffic management system according to an embodiment of the invention. As shown in fig. 3a, the method 300a may include: in step 310, the functional unit can be communicated with via a first communication mode to transmit information related to the functional unit; in step 320, the backend management terminal may communicate with the backend management terminal via a second communication method different from the first communication method to transmit information related to the functional unit, so that the backend management terminal monitors and manages the functional unit according to the information. Step 310 and step 320 have been described in detail in the foregoing with reference to step 210 and step 220 shown in fig. 2, and are not described in detail here.

Next, in step 330, second location information associated with the on-board unit may be obtained using the positioning module. For example, the second location information may be obtained using a positioning module associated with the on-board unit. In some embodiments, the location module may be connected to an on-board unit. In other embodiments, the positioning module may be disposed within a vehicle in which the on-board unit is mounted. In still other embodiments, the positioning module may be disposed within the tachograph. In still other embodiments, the location module may be disposed within the on-board unit. In some embodiments, the positioning module may include a global positioning system GPS positioning module or a beidou satellite positioning module, or the like.

As further shown in fig. 3a, in step 340, the second location information may be sent to the back management end via the second communication mode, so that the back management end locates the vehicle-mounted unit according to the second location information, or locates the road side unit according to the second location information and the second information. In some application scenarios, since the second location information is related to the on-board unit, the backend management end can be directly located to the location of the on-board unit according to the second location information. In other application scenarios, when the on-board unit interacts with the roadside unit, the on-board unit is closer to the roadside unit, and at this time, the background management terminal can be accurately positioned to the position of the roadside unit according to the second position information when the on-board unit interacts with the roadside unit and the first position information in the second information. According to the arrangement, the remote diagnosis of the vehicle-mounted unit and the road side unit is facilitated, and more accurate and timely position information can be provided for the on-site investigation of the road side unit.

While the method for supervising functional units in an intelligent traffic management system according to the embodiment of the present invention is described above with reference to fig. 3a, it will be understood by those skilled in the art that the method 300a shown in fig. 3a is exemplary and not limiting, for example, the execution sequence of the

steps

330 and 340 may not be limited to the one shown after the step 320, and in some embodiments, the step 330 may be executed simultaneously with the step 310 or before the step 320. In other embodiments, step 340 may be performed simultaneously with step 320 or prior to step 320.

Fig. 3b is a flow chart illustrating a method for supervising functional units in an intelligent traffic management system according to yet another embodiment of the present invention. As shown in fig. 3, method 300b may include: in step 350, the functional unit may be communicated via a first communication means to transmit the deduction information and/or deduction result related to the functional unit. It is to be understood that step 350 may be an embodied expression of step 210 described above in connection with fig. 2, and thus the description above with respect to step 210 of fig. 2 may be equally applicable to step 350. For example, the functional unit may be an on-board unit and/or a roadside unit, and in some embodiments, the functional unit is in direct or indirect communication with the roadside unit via the first communication manner, and the transmitted second information may include: fee deduction information for deducting the fee of the vehicle-mounted unit; and a fee deduction result for deducting the fee of the vehicle-mounted unit. In other embodiments, the deduction information may include one or more of a deduction amount, a deduction time, a remaining amount, and the like.

Through the embodiment, in the process of fee deduction of the RSU and the OBU, the fee deduction instruction sent by the RSU can be received through the first communication mode, wherein the fee deduction instruction carries fee deduction information for fee deduction of the OBU to be paid. Optionally, the execution subject of this embodiment may be a vehicle event data recorder, but is not limited thereto, and may also be other vehicle-mounted terminal devices that can receive a related instruction sent by the RSU to the OBU to display the deduction information, such as a central control device, a navigation device, a multifunctional steering wheel, a multifunctional dashboard, and the like.

Next, in step 360, the deduction information may be saved. The OBU equipment has relatively weak storage and data processing functions, cannot realize the purpose of viewing consumption information at any time, and cannot realize historical data summarizing and analysis, so that some big data analysis and display functions which provide convenience for users cannot be realized; on the other hand, the operation of the user on the OBU is relatively less, typically, the card information is obtained by plugging and unplugging the card, and the media access control address MAC, the serial number SN, the historical transaction record and the like of the OBU cannot be inquired or need a special method, which undoubtedly increases the difficulty of using the OBU for the user. According to the embodiment of the invention, the fee deduction information can be stored on the vehicle-mounted terminal equipment such as a vehicle data recorder and the like, so that the operations such as displaying to a user, subsequent user inquiry and the like are facilitated. In some embodiments, the vehicle-mounted terminal device may store the fee deduction information according to the corresponding relationship between the fee deduction time and the fee deduction information after each transaction is successful, so as to facilitate query of the fee deduction information.

As an optional implementation scheme, in order to realize the display of the deduction information of the OBU, the vehicle-mounted terminal device may be firstly bound with the OBU, wherein the vehicle-mounted terminal device and the OBU may be unidirectionally bound, and the vehicle-mounted terminal device is bound with the OBU, but the OBU may not be bound with the vehicle-mounted terminal device. For example, before receiving a deduction instruction sent by the RSU, the vehicle-mounted terminal device may send a broadcast message, where the broadcast message is used to request to acquire identification information of an OBU located within a broadcast range of the vehicle-mounted terminal device; the method comprises the steps that a vehicle-mounted terminal device receives a first response message sent by an OBU response broadcast message, wherein the first response message carries target identification information of the OBU; and the vehicle-mounted terminal equipment binds the vehicle-mounted terminal equipment and the OBU according to the target identification information.

In order to bind with the OBU, the vehicle-mounted terminal device sends a broadcast message to the broadcast range of the vehicle-mounted terminal device to acquire identification information (for example, OBU identification) of the OBU in the broadcast range. The broadcast message may be: a standard broadcast frame BST.

After receiving the broadcast message, the OBU located in the broadcast range may carry identification information (target identification information) of itself in a first response message, and send the first response message to the vehicle-mounted terminal device, where the first response message may be: the frame VST is repeated.

After receiving the first response message, the vehicle-mounted terminal device may extract the target identification information carried in the first response message, and bind the vehicle-mounted terminal device and the OBU according to the target identification information, where the binding mode may be: and writing the target identification information into a specific position of the vehicle-mounted terminal equipment so as to limit the binding relationship between the vehicle-mounted terminal equipment and the OBU.

In other embodiments, after receiving the deduction instruction, the vehicle-mounted terminal device may first determine whether the OBU to be deducted is the OBU bound by the vehicle-mounted terminal device. If yes, the fee deduction information (pre-stored fee deduction information) carried in the fee deduction instruction can be stored. In the case of no judgment, the in-vehicle terminal device may ignore the deduction instruction.

In still other embodiments, after receiving the deduction instruction, the OBU may interact with the RSU according to the deduction instruction, so as to realize deduction of the OBU (the deduction account bound to the OBU). After completing the interaction, the RSU may send a deduction result to the OBU to indicate whether the deduction was successful for the OBU. Besides the OBU, the vehicle-mounted terminal device can also receive the deduction result, and the deduction result is determined to be the deduction result of the OBU bound with the vehicle-mounted terminal device according to the identification information of the OBU carried in the deduction result. In addition, the fee deduction result can be determined to be the fee deduction result corresponding to the received fee deduction instruction through fee deduction identification information carried in the fee deduction result.

Next, as shown in fig. 3b, in step 370, in case that the deduction result is that the deduction is successful, the deduction information may be presented in various ways. For example, according to one embodiment of the present invention, the prompting for fee deduction information may include at least one of the following ways: displaying fee deduction information; and sending out prompt tones for prompting fee deduction information.

As an alternative, displaying the deduction information may include: and displaying the fee deduction information on a screen of the vehicle-mounted terminal equipment. After receiving the deduction result, deduction information may be displayed on a screen of the in-vehicle terminal device, for example, information of the deduction amount, the deduction time, the remaining amount, and the like may be displayed.

As another alternative, the issuing of the prompt tone for prompting the fee deduction information may include: and sending out prompt tone for prompting fee deduction information through audio equipment of the vehicle-mounted terminal equipment. After receiving the fee deduction result, an prompting sound can be sent out through an audio device of the vehicle-mounted terminal device to prompt fee deduction information, such as fee deduction amount, fee deduction time, remaining amount and the like. According to the setting, the user can still know the vehicle fee deduction information under the condition that the user cannot check the display screen, so that the distraction operation of the user can be reduced to ensure the driving safety of the user.

According to the embodiment, the fee deduction information is displayed immediately and/or is prompted through the prompt tone, so that the prompt timeliness of the fee deduction information prompt can be guaranteed, and the user experience is improved.

As further shown in fig. 3b, in step 380, in case the deduction result is a deduction failure, the saved deduction information is deleted. As an alternative, after the vehicle-mounted terminal device receives the deduction result of deducting the fees of the OBU sent by the RSU, if the deduction result is that the fees are not deducted, the vehicle-mounted terminal device may delete the deduction information stored in the vehicle-mounted terminal device.

If the deduction result indicates that the deduction fails, the vehicle-mounted terminal device can delete the deduction information stored in the vehicle-mounted terminal device so as to save the storage space of the vehicle-mounted terminal device. Meanwhile, the vehicle-mounted terminal equipment can also prompt the prompt information of fee deduction failure so as to prompt the user of fee deduction failure. When the user knows the deduction failure, the user can carry out fee compensation through operating the vehicle-mounted terminal equipment or other terminal equipment, and the influence of the deduction failure on the OBU used by the user is avoided.

Through the embodiment, the stored fee deduction information is deleted when the fee deduction fails, so that the storage space of the vehicle-mounted terminal equipment can be saved, and the resource utilization efficiency of the vehicle-mounted terminal equipment is improved.

It should be noted that, in consideration of the low power consumption characteristic of the OBU, in the conventional fee deduction information prompting mode, after the OBU receives the fee deduction result and the fee deduction result is successful, the OBU starts bluetooth and other modes to establish connection between the OBU and the vehicle-mounted terminal device, and the fee deduction information can be sent to the vehicle-mounted terminal device, so that the information prompting is not timely, and the communication burden of the OBU is increased. The information prompting method provided by the embodiment of the invention can directly use the first communication mode to communicate with the OBU and/or the RSU, can be based on the data transmission protocol and mode of the existing ETC transaction system, and can be completely compatible with the existing OBU transaction system, so that the transaction information can be directly obtained in the transaction process of the OBU, and can be displayed immediately, and other software and hardware resources of the OBU are not additionally used, which is particularly important for the OBU powered by a battery.

According to another embodiment of the present invention, after prompting the deduction information, the method 300b may further include: in response to receiving a query instruction, acquiring fee deduction bill information corresponding to the target time length from the saved fee deduction historical record, wherein the query instruction can be used for querying the fee deduction bill information of the vehicle-mounted unit in the target time length; and displaying the information of the deduction bill. In some embodiments, the saved deduction history may include deduction information or the like.

In some application scenarios, a user may query the charging bill information (or called consumption bill information) within a target time length by operating a touch screen of the vehicle-mounted terminal device or by means of a voice instruction. The target time duration may be a user-specified time duration, such as a specified month (e.g., monthly bills of consumption), a specified year (e.g., yearly bills of consumption), a specified date or a specified start-stop time (e.g., bills of consumption for a particular period of time), and so forth. The vehicle-mounted terminal device can display a selection interface of the target time length through the touch screen, and after receiving a selection operation of the target time length and determining a control instruction of query, or after receiving a voice query instruction containing indication information of the target time length, obtains the fee deduction bill information corresponding to the target time length by querying the stored fee deduction history record, and displays the fee deduction bill information on a screen (such as the touch screen) of the vehicle-mounted terminal device.

Through the embodiment, the vehicle-mounted terminal equipment is used for storing the deduction history record and responding to the inquiry instruction to display the deduction bill information in the target time length, so that the operation on the OBU can be reduced, and the improvement on the information acquisition capability of a user can be facilitated.
