Specific embodiments of the present invention are described in detail below with reference 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 an on-board unit according to an embodiment of the present invention. In the context of the present invention, the aforementioned scenario may be an interactive scenario in which a function detection is performed between the in-vehicle unit 101 and the device 102 mounted on various types of vehicles. For example, the method specifically may include a scenario of function detection before the front-loading OBU is offline, a scenario of function detection after the rear-loading OBU is sold, or other application scenarios in which the OBU needs to perform function detection. The specific installation position of the OBU is not limited herein, and may be installed, for example, at a windshield of a vehicle or other suitable location. And the specific structure of the device 102 will be described below.
In the practical application process, the vehicle-mounted unit 101 can support multiple communication protocols, and the device 102 interacts with the vehicle-mounted unit 101 based on the communication protocols, so that high-efficiency and accurate detection of functions of the vehicle-mounted units on different vehicles can be realized.
Fig. 2 is a flow chart illustrating one method 200 for detecting an on-board unit according to an embodiment of the present invention. It should be noted that the method 200 may be understood as a specific interaction procedure between the device 102 and the on-board unit 101 in fig. 1, and may be specifically performed on the device 102 side. Accordingly, the detailed description hereinbefore described with reference to fig. 1 applies equally to the following.
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 herein may include an existing communication protocol that may be supported by the on-board unit, such as a dedicated short-range communication protocol, a bluetooth communication protocol, or other supportable communication protocol, or a communication protocol that is newly added as the function of the on-board unit is improved, or the like. And the aforementioned first identification information may include information capable of uniquely identifying the on-board unit, such as a product serial number SN, etc. It should be noted that the detailed description of the communication protocol and the first identification information is only an exemplary description.
Next, at step S202, a function detection operation with respect to each communication protocol may be performed in response to acquiring the first identification information with respect to the in-vehicle unit based on the plurality of communication protocols. In some embodiments, the on-board unit may send its own 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 can be implemented by the interaction data forwarded by the corresponding communication protocol.
Next, at step S203, the function detection result for each communication protocol may be stored in association with the aforementioned first identification information. By combining the function detection of the vehicle-mounted unit with a communication protocol supporting the function detection, and binding different detection results with the first identification information of the vehicle-mounted unit. According to the scheme, the comprehensive and efficient function detection of the vehicle-mounted unit can be completed without introducing excessive manual intervention. Particularly, the detection before the front loading vehicle-mounted units are off line in a batched mode can greatly shorten the detection time of the whole production line, and meanwhile, the matching accuracy of the detection result and the vehicle-mounted units is improved.
Fig. 3 is a flow chart illustrating another method 300 for detecting an on-board unit according to an embodiment of the present invention. It should be noted that the method 300 may be understood as a specific interaction procedure between the device 102 and the on-board unit 101 in fig. 1, and further optimization and expansion of the method 200 in fig. 2. Accordingly, the detailed description hereinbefore described with reference to fig. 1 and 2 applies equally to the following. In addition, in the present embodiment, description will be given taking an example in which the aforementioned plurality of communication protocols may include a first communication protocol and a 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 herein may include the aforementioned first identification information and second identification information regarding the second communication protocol. In some embodiments, the first identification information may include SN information, as previously described. 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, and 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 the aforementioned target information being acquired based on the first communication protocol. It should be noted that, in practical application, the on-board unit may perform different functions based on different communication protocols, so 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 via the second identification information and establish a connection therewith in a second communication protocol. Then, after the first identification information is obtained through the second communication protocol, a corresponding function detection operation can be performed (specifically, the setting and adjustment can be performed according to the functions supported by the second communication protocol and actual test requirements).
Next, at step S305, the function detection result regarding 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 corresponding detection operation by fully utilizing the advantages of different communication protocols. In particular, the functions of the on-board unit can be detected independently, so that after the short-time function detection of the on-board unit is completed, the function detection of the next on-board unit can be executed, and the function detection of the next on-board unit does not need to be started after all other functions of the current on-board unit are detected, thereby further improving the detection efficiency.
Fig. 4 is a flow chart illustrating yet another method 400 for detecting an on-board unit according to an embodiment of the present invention. It should be understood that the method 400 is understood to be a specific interaction process between the device 102 and the on-board unit 101 in fig. 1, and further optimization and expansion of the method 300 in fig. 3. Accordingly, the detailed description hereinbefore described with reference to fig. 1 and 3 applies equally to the following. In addition, in the present embodiment, description will be given taking an example in which the aforementioned first communication protocol may include the dedicated short-range communication protocol DSRC and the second communication protocol may include the 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 on-board unit, etc.) and second identification information (e.g., bluetooth address information of the on-board unit, etc.). After the on-board unit establishes connection with the device through the dedicated short-range communication protocol, the on-board unit may send its own SN information and bluetooth address information to the device.
Next, at step S402, a detection operation regarding the no-parking charging transaction function may be performed in response to the acquisition of the aforementioned target information. It should be noted that, the specific short-range communication protocol is taken as an example to support the function of toll collection, and the scheme of the present invention is not limited thereto. The detection of other functions that can be supported by the dedicated short-range communication protocol can also be performed, for example, according to test requirements.
Next, at step S403, communication may be established with the on-board unit based on the second identification information to obtain the first identification information through a bluetooth communication protocol. As described above, the second identification information here may be bluetooth address information. Specifically, after the bluetooth address information is obtained through the dedicated short-range communication protocol, the bluetooth function of the vehicle-mounted unit can be triggered to be started first, and connection with the vehicle-mounted 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 underlying communication functions of bluetooth, protocols regarding the issuer (e.g., the execution standard of the protocols), etc. may be detected. Next, at step S405, the function detection result for each communication protocol may be stored in association with a 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 previously described, the function detection result associated with the aforementioned first identification information may include a detection result of a toll collection transaction function and a detection result of a bluetooth communication function. And when the detection results are determined to meet the preset conditions, the non-stop toll collection transaction function is normal and the Bluetooth communication function is normal. At this time, step S406 may be performed to write the vehicle identification information VIN of the vehicle in which the aforementioned in-vehicle unit is located in the in-vehicle unit. Specifically, the vehicle identification information VIN may be written in the in-vehicle unit based on the second identification information and the channel constructed by the in-vehicle unit. For example, when the second identification information is bluetooth address information, it is possible to, after determining that both the toll collection transaction function and the bluetooth communication function are normal, not disconnect the bluetooth channel and continue to perform an operation of writing the vehicle identification information VIN to the in-vehicle unit through the bluetooth channel. Correspondingly, the correspondence between the first communication identifier (for example, SN information of the on-board unit) and the vehicle identifier information VIN may be stored in the device 102 in advance, or may be obtained from the outside. Based on this, it is possible to effectively avoid the vehicle identification information from being wrongly written into the faulty on-board unit or other on-board units.
Fig. 5 is a block diagram showing the construction of an apparatus 500 for detecting an on-board unit according to an embodiment of the present invention. It should be noted that one possible exemplary implementation carrier of the method 300 described above in connection with fig. 3 may be the apparatus 500. Accordingly, the detailed description hereinbefore described with reference to fig. 3 applies equally as well to the following.
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 obtain first identification information about the on-board unit via 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 obtain the aforementioned first identification information; and a controller 503, which may be connected to the roadside simulator 501 and all communication hosts 502, and may be configured to perform the following operations: after the roadside simulator 501 acquires the first identification information, a function detection operation with respect to the first communication protocol may be performed. It should be noted that, in performing the function detection operation process with respect to the first communication protocol, the required interaction information may be transmitted or received through 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 result regarding 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 not only can realize the accurate matching of the detection result and the vehicle-mounted unit, but also can independently execute corresponding detection operation by fully utilizing the advantages of different communication protocols. In particular, the different functions of the on-board unit can be independently detected, so that after the short-time function detection of the on-board unit is completed, the function detection of the next on-board unit can be performed, thereby further improving the detection efficiency.
Fig. 6 is a block diagram illustrating another apparatus 600 for detecting an on-board unit according to an embodiment of the present invention. It should be noted that one possible exemplary implementation carrier of the method described above in connection with fig. 2-4 may be the apparatus 600. In addition, the apparatus 600 may be viewed as a further optimization and extension of the apparatus 500. Accordingly, the detailed description hereinbefore described with reference to fig. 2 to 5 applies equally to the following.
As shown in fig. 6, the apparatus 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. Wherein the performance of the RSU antenna 601 is calibrated to meet the actual road application standard. In particular, the RSU antenna 601 may be provided on a gantry and used to transmit and receive radio frequency signals. And bluetooth host 602 may be connected to an on-board unit and a controller. The controller 603 may run traffic control software and databases and all control strategies may be implemented by the control software. The output module 604 may include a display or a printer that may be used to output the detection results of the on-board unit. The database module 605 may record information regarding the vehicle under test and the on-board unit installed on the vehicle (e.g., vehicle VIN information, SN information of the on-board unit, correspondence thereof, etc.). For example, when an OBU is installed for a vehicle on a transmission 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 alone or can be designed integrally with the controller. In addition, the conveyor mechanism 606 may be a general purpose conveyor belt conveyor mechanism for carrying the vehicle under test.
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 the SN number and Bluetooth address information of an OBU on a certain vehicle through a special short-range communication protocol DSRC. Then, an OBU bluetooth broadcast command may be sent to be turned on, and the obtained SN number and bluetooth address information of the OBU may be transmitted to the controller for storage. After the detection of the no-parking charge transaction function (hereinafter referred to as transaction function) of the OBU is completed, the DSRC detection link with the OBU may be disconnected, and the transaction detection result may be transmitted to the controller for storing the transaction information of the OBU. Because of the faster detection speed based on DSRC, the RSU antenna can continue to perform transaction function detection of the OBU on other vehicles. The controller sequentially stores the obtained SN number of the OBU, bluetooth address information and corresponding transaction detection results.
In some embodiments, the controller may turn on a scan pattern for a significant number of bluetooth hosts based on the number of bluetooth addresses acquired to be detected. Specifically, the bluetooth host may connect according to the sequence of 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 wait for the scanning connection after releasing the idle state.
In some embodiments, the OBU may turn on the bluetooth broadcast mode after receiving a bluetooth broadcast on command sent by the RSU antenna. Specifically, the bluetooth broadcast status of the OBU may last for a certain time to wait for a connection to an idle bluetooth host. After an idle Bluetooth host is connected with the OBU, the SN number of the OBU can be acquired through a Bluetooth communication protocol, and the Bluetooth communication function of the OBU is detected. 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 acceptable, and when the transaction detection result corresponding to the SN number of the OBU is also acceptable by querying, the database module may be queried to obtain the vehicle identifier VIN code corresponding to the SN. The VIN code may then be written into the corresponding OBU over the currently established bluetooth communication link and control the bluetooth connection to be disconnected. The detection results of the transaction function and bluetooth function of the OBU may then be displayed by a display or printed out by a printer. And when one of the transaction function and the Bluetooth communication function of the OBU is disqualified, the Bluetooth connection disconnection can be directly controlled. Then, the controller can store and record, display or print the detection result information, and no longer write the VIN code to the fault OBU.
Based on the above, the scheme of the invention can improve the automation degree of OBU (particularly vehicle enterprise OBU) detection, and Bluetooth function detection is added on the basis of transaction function detection so as to improve the comprehensiveness of function detection. Meanwhile, the problem of poor matching accuracy in the existing OBU offline detection technology is solved, ETC production line detection time is effectively saved, and therefore detection efficiency of the OBU offline is greatly improved.
In addition, for higher detection efficiency, the RSU antenna is not limited to starting to detect the next vehicle after completing all the function detection of the OBU of the current vehicle. Instead, the RSU antenna may continue to detect DSRC functions of the next or more nearby vehicles while the bluetooth host detects bluetooth functions of the current vehicle. And other idle Bluetooth hosts are connected with corresponding OBUs according to the sequence of Bluetooth addresses received by the controller so as to detect the Bluetooth communication function of the Bluetooth hosts. Therefore, the controller can independently process the detection of the transaction function and the Bluetooth function, and the detection efficiency can be greatly improved on the basis of ensuring the accuracy.
