Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims.

Thus, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section.

The following detailed description of embodiments of the invention refers to the accompanying drawings.
In order to better understand the solution of the present invention, the detection process of the on-board unit will be described below with reference to fig. 1.
FIG. 1 is a diagram illustrating an exemplary scenario of a system 100 for detecting on-board units according to an embodiment of the present invention. In the context of the present invention, the aforementioned scenario may be an interaction scenario for function detection between the onboard unit 101 and the device 102 mounted on various types of vehicles. For example, the function detection method may specifically include a scenario for function detection before the front-mounted OBU is offline, a scenario for function detection after the rear-mounted OBU is sold, or another application scenario requiring function detection of the OBU. It should be noted that the specific installation position of the OBU is not limited herein, and may be installed at the windshield of the vehicle or other suitable positions, for example. And the specific structure of the device 102 will be described below.
In the actual application process, the on-board unit 101 can support multiple communication protocols, and the device 102 interacts with the on-board unit 101 based on the communication protocols, so that the functions of the on-board units on different vehicles can be efficiently and accurately detected.
FIG. 2 is a flow chart illustrating one method 200 for detecting an on-board unit in accordance with an embodiment of the present invention. It should be noted that the method 200 may be understood as a specific interaction process between the device 102 and the vehicle-mounted unit 101 in fig. 1, and may be specifically executed on the device 102 side. Therefore, the detailed description above in connection with fig. 1 also applies below.
As shown in fig. 2, at step S201, it may be detected whether first identification information about the in-vehicle unit is acquired based on a plurality of communication protocols. The communication protocol may include an existing communication protocol that the on-board unit can support, such as a dedicated short-range communication protocol, a bluetooth communication protocol, or other supportable communication protocols, or a communication protocol added as the function of the on-board unit is improved. And the aforementioned first identification information may include information capable of uniquely identifying the on-board unit, such as a product serial number SN or the like. It should be noted that the detailed descriptions of the communication protocol and the first identification information are only examples.
Next, at step S202, a function detection operation with respect to each communication protocol may be performed in response to acquisition of the first identification information with respect to the in-vehicle unit based on the plurality of communication protocols. In some embodiments, the onboard unit may send its first identification information to the device after establishing a communication connection with the device via a different communication protocol. The function detection of the on-board unit may be specifically implemented by interactive data forwarded by a corresponding communication protocol.
Next, at step S203, the function detection result with respect to each communication protocol may be stored in association with the aforementioned first identification information. The function detection of the vehicle-mounted unit is combined with a communication protocol supporting the function detection, and different detection results are bound with the first identification information of the vehicle-mounted unit. Therefore, the scheme of the invention can complete comprehensive and efficient function detection of the vehicle-mounted unit without introducing excessive manual intervention. The detection before the line is unloaded to the on-vehicle unit of front-mounted of batch very much, can reduce whole production line check-out time greatly, improve the matching precision of testing result and on-vehicle unit simultaneously.
FIG. 3 is a flow chart illustrating another method 300 for detecting on-board units in accordance with an embodiment of the present invention. It should be noted that the method 300 can be understood as a specific interaction process of the device 102 and the on-board unit 101 in fig. 1, and further optimization and expansion of the method 200 in fig. 2. The same applies to the following, therefore, as described in detail above in connection with fig. 1 and 2. In addition, in this embodiment, a description will be given taking an example in which the plurality of communication protocols may include the first communication protocol and the second communication protocol.
As shown in fig. 3, at step S301, it may be detected whether target information is acquired based on the first communication protocol. The target information here may include the aforementioned first identification information and second identification information regarding the second communication protocol. In some embodiments, as previously described, the first identification information may include SN information. And the second identification information may include information capable of identifying the second communication protocol attribute, such as address information or the like. It should be noted that the description of the first identification information and the second identification information is only an exemplary description, for example, the second identification information may be specifically adjusted according to the communication connection attribute of the second communication protocol.
Next, at step S302, a function detection operation with respect to the first communication protocol may be performed in response to acquisition of the aforementioned target information based on the first communication protocol. It should be noted that, in practical applications, the on-board unit may perform different functions based on different communication protocols, and therefore, the function detection operation herein may be set and adjusted according to the functions supported by the first communication protocol and the actual test requirements.
Next, at step S303, communication may be established with the in-vehicle unit based on the aforementioned second identification information to acquire the first identification information through the second communication protocol. And at step S304, a function detection operation with respect to the second communication protocol may be performed. In some embodiments, the device may determine the on-board unit from the second identification information and establish a connection with it in the second communication protocol. Then, after the first identification information is obtained through the second communication protocol, a corresponding function detection operation may be executed (specifically, the setting and adjustment may be performed according to the function supported by the second communication protocol and the actual test requirement).
Next, at step S305, the function detection result with respect to each of the above-described communication protocols may be stored in association with the first identification information. Therefore, the scheme of the invention not only can realize the accurate matching of the detection result and the vehicle-mounted unit, but also can independently execute the corresponding detection operation by fully utilizing the advantages of different communication protocols. In particular, different functions of the on-board unit can be independently detected, so that the function detection of the next on-board unit can be executed after the function detection of one on-board unit with short time is completed, and the function detection of the next on-board unit is started without waiting for the completion of all other function detections of the current on-board unit, thereby further improving the detection efficiency.
FIG. 4 is a flow chart illustrating yet another method 400 for detecting an on-board unit in accordance with an embodiment of the present invention. It should be understood that the method 400 can be understood as a specific interaction process of the device 102 and the on-board unit 101 in fig. 1, and further optimization and expansion of the method 300 in fig. 3. Therefore, the same applies to the following description in connection with the details in fig. 1 and 3. In addition, in the present embodiment, a description will be given taking an example in which the aforementioned first communication protocol may include a dedicated short range communication protocol DSRC and the second communication protocol may include a bluetooth communication protocol.
As shown in fig. 4, at step S401, it may be detected whether the target information is acquired based on the dedicated short range communication protocol. In some embodiments, the aforementioned target information may include first identification information (e.g., SN information of the in-vehicle unit, etc.) and second identification information (e.g., bluetooth address information of the in-vehicle unit, etc.). After the on-board unit establishes connection with the device through a special short-range communication protocol, the on-board unit can send the SN information and the Bluetooth address information of the on-board unit to the device.
Next, at step S402, a detection operation regarding the electronic toll collection transaction function may be performed in response to the acquisition of the aforementioned target information. It should be noted that, the description is given by taking an example in which a dedicated short-range communication protocol can support the electronic toll collection transaction function, and the scheme of the present invention is not limited thereto. For example, the detection of other functions supportable by the dedicated short-range communication protocol may also be performed according to test requirements.
Next, at step S403, communication may be established with the on-board unit based on the second identification information to acquire the first identification information through the bluetooth communication protocol. As described above, the second identification information may be bluetooth address information. Specifically, after the bluetooth address information is acquired through the dedicated short-range communication protocol, the bluetooth function of the on-board unit may be triggered to be started first, and the connection with the on-board unit is established through the bluetooth communication protocol according to the subsequent detection requirement.
Next, at step S404, a detection operation regarding the bluetooth communication function may be performed based on the bluetooth communication protocol. For example, the basic communication function of bluetooth, a protocol (e.g., an execution standard of the protocol) with respect to an issuer, and the like may be detected. Next, at step S405, the function detection result with respect to each communication protocol may be stored in association with the first communication identification (e.g., SN information of the in-vehicle unit).
Then, at step S406, it may be detected whether the function detection result associated with the aforementioned first identification information satisfies a preset condition. In some embodiments, as described above, the function detection result associated with the aforementioned first identification information may include a detection result of the electronic toll collection transaction function and a detection result of the bluetooth communication function. When the detection results meet the preset conditions, the normal functions of the ETC transaction and the Bluetooth communication are indicated. At this time, step S406 may be executed to write the vehicle identification information VIN of the vehicle in which the aforementioned vehicle-mounted unit is located into the vehicle-mounted unit. Specifically, the vehicle identification information VIN may be written into the on-board unit based on the second identification information and the channel constructed by the on-board unit. For example, when the second identification information is bluetooth address information, after determining that the electronic toll collection transaction function and the bluetooth communication function are both normal, the bluetooth channel is not disconnected, and the operation of writing the vehicle identification information VIN into the vehicle-mounted unit is continuously performed through the bluetooth channel. Correspondingly, the device 102 may store the corresponding relationship between the first communication identifier (for example, SN information of the vehicle-mounted unit) and the vehicle identification information VIN in advance, or may obtain the first communication identifier and the vehicle identification information VIN from the outside. Based on this, it is possible to effectively prevent the vehicle identification information from being wrongly written in the malfunctioning on-board unit or other on-board units.
Fig. 5 is a block diagram illustrating a structure of an apparatus 500 for detecting an in-vehicle unit according to an embodiment of the present invention. It is noted that one possible exemplary implementation vehicle for the method 300 described above in connection with fig. 3 may be the apparatus 500. Therefore, the detailed description above in connection with fig. 3 also applies below.
As shown in fig. 5, the apparatus 500 may include a roadside simulator 501, at least one communication host 502, and a controller 503. Wherein, the roadside simulator 501 may be configured to acquire first identification information on the on-board unit through a first communication protocol; the communication host 502 may be configured to establish a communication connection with the on-board unit through a second communication protocol, and acquire the aforementioned first identification information; and a controller 503, which may be connected with the roadside simulator 501 and all communication hosts 502, and may be configured to perform the following operations: after the first identification information is acquired by the roadside simulator 501, a function detection operation with respect to the first communication protocol may be performed. It should be noted that, during the execution of the function detection operation with respect to the first communication protocol, the required interaction information may be transmitted or received by the roadside simulator 501. Next, after each communication host 502 acquires the first identification information, a function detection operation with respect to the second communication protocol may be performed. Then, the function detection results on the first communication protocol and the second communication protocol may be stored in association with the first identification information.
Therefore, the scheme of the invention can complete comprehensive and efficient function detection of the vehicle-mounted unit without introducing excessive manual intervention. The whole detection process can not only realize the accurate matching of the detection result and the vehicle-mounted unit, but also independently execute the corresponding detection operation by fully utilizing the advantages of different communication protocols. In particular, different functions of the on-board unit can be independently detected, so that the function detection of the next on-board unit can be executed after the function detection of one on-board unit with short time is completed, and the detection efficiency is further improved.
Fig. 6 is a block diagram illustrating the configuration of another apparatus 600 for detecting an in-vehicle unit according to an embodiment of the present invention. It should be noted that one possible exemplary execution vehicle for the methods described above in connection with fig. 2-4 may be the apparatus 600. Additionally, the apparatus 600 may be seen as a further optimization and expansion of the apparatus 500. Therefore, the detailed description above in connection with fig. 2 to 5 also applies below.
As shown in fig. 6, device 600 may include an RSU antenna 601, a plurality of bluetooth hosts 602 and controllers 603, an output module 604, a database module 605, and a transport mechanism 606. The performance of the RSU antenna 601 is calibrated to meet the actual road application standard. Specifically, the RSU antenna 601 may be disposed on the gantry and used for transmitting and receiving radio frequency signals. And the bluetooth host 602 may be connected to the on-board unit and the controller. The controller 603 may run service control software and databases and all control strategies may be performed by the control software. The output module 604 may include a display or a printer, which may be used to output the detection results for the on-board unit. The database module 605 may record the relevant information (e.g., vehicle VIN information, SN information of the vehicle-mounted unit, and the corresponding relationship thereof) of the vehicle to be tested and the vehicle-mounted unit mounted on the vehicle. For example, when an OBU is installed for a vehicle on a transport mechanism, a one-to-one correspondence of vehicle identification (VIN code) and OBU identification (SN number) may be recorded and stored to the database module. The database module can exist independently or can be designed integrally with the controller. In addition, the transport mechanism 606 may employ a general conveyor transport mechanism for carrying the vehicles to be tested.
In practical application, when different types of vehicles provided with vehicle-mounted units approach the RSU antenna through the transmission mechanism, the RSU antenna can acquire SN (serial number) and Bluetooth address information of an OBU (on-board unit) on a certain vehicle through a special short-range communication protocol DSRC (dedicated short range communication). Then, an OBU Bluetooth broadcast opening instruction can be sent, and the acquired SN number and Bluetooth address information of the OBU are transmitted to the controller to be stored. After the detection of the non-stop charging transaction function (hereinafter referred to as transaction function) of the OBU is completed, the DSRC detection link with the OBU can be disconnected, and the transaction detection result can be transmitted to the controller for storing the transaction information of the OBU. Due to the relatively fast DSRC-based detection speed, the RSU antenna can continue transaction function detection for OBUs on other vehicles. And the controller will store the acquired SN number of the OBU, bluetooth address information and corresponding transaction detection results in succession.
In some embodiments, the controller may turn on the scan mode of a significant number of bluetooth hosts according to the number of acquired bluetooth addresses to be detected. Specifically, the bluetooth host may connect according to the order of the bluetooth address information acquired by the controller. If the number of the Bluetooth addresses to be detected exceeds the number of the Bluetooth hosts, the Bluetooth hosts can be waited to release the idle state and then scan and connect.
In some embodiments, the OBU may turn on the bluetooth broadcast mode after receiving the bluetooth broadcast turning on instruction sent by the RSU antenna. Specifically, the bluetooth broadcast state of the OBU may last for a certain time to wait for a connection with an idle bluetooth host. After having idle bluetooth host computer and OBU to be connected, can acquire this OBU's SN number through bluetooth communication protocol to begin to detect OBU's bluetooth communication function. The detection result information may then be sent to the controller for storage.
In some embodiments, when the controller detects that the bluetooth function of the OBU is qualified and a transaction detection result corresponding to the SN number of the OBU is also qualified by querying, the controller may query the database module to obtain the vehicle identification VIN code corresponding to the SN. Then, the VIN code can be written into the corresponding OBU through the currently established bluetooth communication link, and the bluetooth connection is controlled to be disconnected. Then, the detection results of the transaction function and the Bluetooth function of the OBU can be displayed through a display or printed out through a printer. And when one of the transaction function and the Bluetooth communication function of the OBU is unqualified, the Bluetooth connection can be directly controlled to be disconnected. Then, the controller can store and record the detection result information, display or print the detection result information, and the VIN code is not written to the fault OBU any more.
Based on the technical scheme, the automatic detection degree of the OBU (especially the OBU of the vehicle and the enterprise is offline) can be improved, and the Bluetooth function detection is added on the basis of detecting the transaction function so as to improve the comprehensiveness of the function detection. Simultaneously, still solved the poor problem of the matching degree of accuracy that current OBU detection technique exists that rolls off the production line, effectively practiced thrift ETC and produced line check-out time to detection efficiency when the OBU rolls off the production line has been improved greatly.
In addition, for higher detection efficiency, the RSU antenna is not limited to starting to detect the next vehicle after completing the OBU full function detection of the current vehicle. Instead, the RSU antenna may continue to detect DSRC functions for the next or more close-range vehicles while the bluetooth host detects bluetooth functions for the current vehicle. And other idle Bluetooth hosts are connected with corresponding OBUs according to the sequence of the Bluetooth addresses received by the controller so as to detect the Bluetooth communication function of the OBUs. From this, the controller can be with the detection independent processing of transaction function and bluetooth function, can improve detection efficiency greatly on the basis of ensureing the degree of accuracy.
