Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The vehicle-road cooperation is that the vehicle, the road and the cloud can realize the interactive sharing of the information of the three. The smart city can acquire crossing sensing information according to sensing equipment bound to each crossing, such as a gun camera, a CCU (Central Control Unit ) collector and a camera, and transmits the information to a roadside computing unit (Road Side Computing Unit, RSCU) for edge computing to analyze traffic conditions, and then reports the traffic conditions to the cloud platform according to fixed frequency. The cloud control platform can also send messages to RSCU equipment corresponding to the intersection, and the RSCU equipment transmits the information to the vehicle end through the RSCU auxiliary equipment so as to realize the interaction of the three information. In the vehicle-road cooperation technology, the cloud control platform can finish the functions of information storage, data fusion, road condition display, event forwarding center and the like. The stability test of the forwarding link from the end to the end of the intersection is particularly important to the field of vehicle-road coordination in order to achieve the objective of barrier-free communication among vehicles, roads and clouds.
In the end-to-end integrated test link, the function to be tested is logic of the cloud control platform for forwarding the RSCU reporting event at the road side. The coverage range of the reporting event is configured at the cloud control platform end, so that the range of the RSCU of the reporting event, which is broadcasted to other road junctions, can be indirectly controlled. In making forwarding test logic and links corresponding to end-to-end communications of vehicles, roads and clouds, multiple intersections with distances within the cloud control platform configuration range, such as intersections 1, 2, 3 … N, need to be accessed. If the event reported by the intersection 1 can be forwarded to RSCU equipment corresponding to other intersections (2, 3..N), the intersection 1 equipment is required to report a stable traffic event, and then the RSCU broadcasting range is configured on the cloud control platform, for example, the broadcasting range is 500 meters. If intersection 2 exists within 1500 meters of intersection, then the RSCU corresponding to intersection 2 will receive the event forwarded from the cloud control platform (this event is reported from the RSCU device on intersection 1). The forwarding logic is realized by a cloud control platform end, so that the forwarding function of the road side equipment is indirectly realized.
Currently, the only platform environments that can verify the forwarding logic are the commercialized delivered environments and the integrated test environments. The commercial delivered environment can be accessed into tens of real intersections, but the distance between the real intersections is fixed, the distance scene verification for different situations is limited, and the function of verifying instant broadcast events by running the intersections in different areas at the vehicle ends in the real scene is not practical. And the commercial delivered environment prohibits similar end-to-end testing by simulating reporting of false data events.
Specifically, when testing the end-to-end forwarding link stability between intersections in a commercialized delivered environment, it is necessary to calculate the distance between two real intersections from each other, and then drive the vehicle to the corresponding intersection to grab the instant event, or view the forwarded event log at the device of the forwarded road side. Because the real scene distance has the shortcoming of fixed death, the intersection scene is insufficient to cover various event broadcasting ranges related to the cloud control platform: 0 meter, 300 meters, 500 meters, 1000 meters, 1500 meters and 2000 meters.
And testing broadcasting logic of an end-to-end link in an integrated test environment, wherein the integrated test environment is only accessed to one intersection of real data at present, and cannot finish the test task of the stability of the end-to-end link among a plurality of intersections. Therefore, the existing method for testing the stability of the end-to-end forwarding link between intersections has poor flexibility, and has low accuracy, success rate and test efficiency.
In one example, fig. 1 is a flowchart of a link testing method provided in an embodiment of the present disclosure, where the embodiment may be applicable to a case of introducing a virtual intersection to perform an end-to-end forwarding link stability test between intersections, the method may be performed by a link testing device, and the device may be implemented by software and/or hardware, and may be generally integrated in an electronic device. The electronic device may be a device in which the link test system is installed, and the embodiments of the present disclosure are not limited to a specific device type of the electronic device. Accordingly, as shown in fig. 1, the method includes the following operations:
S110, acquiring link test transmission data of a first road port test end.
The first intersection test end may be a test end of one of the intersections in the end-to-end forwarding link between the intersections. The intersection test end can be RSCU equipment of the intersection. The link test transmission data may be test data transmitted by the first intersection test end and used for testing the stability of the end-to-end forwarding link between intersections.
In the embodiment of the disclosure, the first intersection testing end can be used as a testing initiating end, and the link testing sending data is sent to the second intersection testing end. The second intersection test end can be a test end of another intersection in the end-to-end forwarding link between intersections, and is used for receiving data obtained by forwarding logic of link test sending data. Optionally, the first intersection testing end or the second intersection testing end is a virtual intersection testing end. The virtual intersection test terminal is a virtual test terminal obtained by simulating the real intersection test terminal, and can simulate the real intersection test terminal to send and receive test data.
Optionally, when the first intersection testing end is a virtual intersection testing end, the first intersection testing end can simulate the real intersection testing end to generate link test sending data. It can be understood that the link test transmission data is virtual test data generated in a virtual intersection scene, and is not real test data collected in a real intersection scene. When the first intersection testing end is a real intersection testing end, the first intersection testing end can generate real link testing sending data according to the real scene of the intersection.
In general, in order to realize effective testing of a real intersection, one of the first intersection testing end and the second intersection testing end may be set as a virtual intersection testing end, and the other one is a real intersection testing end. The first intersection test end and the second intersection test end may be virtual intersection test ends, which is not limited by the embodiment of the disclosure.
It should be noted that, when the first intersection testing end is a virtual intersection testing end, the configuration of the virtual intersection testing end may be implemented in a plurality of optional manners. For example, a virtual intersection test end can be established through the configuration of an independent server, and communication connection between the server and the cloud control platform is established, so that the virtual intersection test end truly simulates the real intersection test end to send link test sending data. At this time, the cloud control platform can receive link test sending data sent by the first road port testing end. Or, the virtual intersection testing end can also be directly configured and established on the cloud control platform, namely, the virtual intersection testing end is used as a sub-service function of the cloud control platform, the link test sending data can be automatically generated and sent to the cloud control platform, and the cloud control platform can generate the link test sending data of the first intersection testing end. The embodiment of the disclosure does not limit the configuration establishing mode of the virtual intersection testing end.
S120, the link test sending data are sent to a second intersection test end.
The embodiment of the disclosure is mainly based on a cloud control platform in a link test system to realize a flow of link test. The first road condition testing end can send the link test sending data to the cloud control platform, or the cloud control platform can generate the link test sending data of the first road condition testing end. After the cloud control platform acquires the link test transmission data of the first intersection test end, the cloud control platform executes forwarding logic, and the acquired link test transmission data is transmitted to the second intersection test end.
S130, acquiring link test receiving data of the second intersection test end.
The link test receiving data may be test data received by the second intersection test terminal for the link test transmitting data. It will be appreciated that the link test received data may be the same as the link test transmitted data or may be different.
S140, determining intersection forwarding link test results of the first intersection test end and the second intersection test end according to the link test sending data and the link test receiving data; the first intersection testing end or the second intersection testing end is a virtual intersection testing end.
The test result of the crossing forwarding link may be a test result of transmitting and receiving data by a link between the first crossing test end and the second crossing test end.
Correspondingly, after the cloud control platform sends the link test sending data to the second intersection test end, the link test system can acquire the link test receiving data of the second intersection test end and conduct link test based on the link test sending data and the link test receiving data. For example, the link test sending data and the link test receiving data may be compared and checked to determine whether the link test sending data and the link test receiving data are matched, and further determine the intersection forwarding link test result of the first intersection test end and the second intersection test end according to the comparison and check result of the link test sending data and the link test receiving data.
It will be appreciated that the above-described link testing method is accomplished based on a link testing system. The link test system can only be composed of a cloud control platform, in this case, the functions of the virtual intersection test end are required to be integrated and deployed on the cloud control platform, and the cloud control platform independently completes the whole link test flow.
Or, the link test system may be composed of a cloud control platform and a test server, where the test server may independently complete the functions of the virtual intersection test ends, and is configured to interact with the cloud control platform by setting up one of the intersection test ends, send link test sending data or link test receiving data to the cloud control platform, and determine intersection forwarding link test results of the first intersection test end and the second intersection test end according to the link test sending data and the link test receiving data by the cloud control platform.
Or, the link test system can also be composed of a cloud control platform, a test server and a link test service, wherein the test server can independently complete the functions of the virtual intersection test terminals and is used for establishing and configuring one intersection test terminal to interact with the cloud control platform, and sending link test sending data to the cloud control platform or receiving link test receiving data forwarded by the cloud control platform. The cloud control platform is only responsible for data forwarding logic. The link test service can independently acquire link test sending data and link test receiving data, and determine intersection forwarding link test results of the first intersection test end and the second intersection test end according to the acquired link test sending data and link test receiving data.
That is, as long as the link test system can complete the link test flow, the embodiments of the present disclosure do not limit the types of execution subjects involved in each step of the link test method performed by the link test system.
It should be noted that, in the embodiment of the present disclosure, the first intersection testing end or the second intersection testing end may be a virtual intersection testing end. That is, when the link test is performed, the first intersection test end may be a virtual intersection test end, and the second intersection test end may be a real intersection test end. Or the first intersection test end can be a real intersection test end, and the second intersection test end can be a virtual intersection test end. Or, the first intersection testing end and the second intersection testing end are virtual intersection testing ends. By introducing the virtual intersection test end to cooperate with the real intersection test end to test the stability of the end-to-end forwarding link between the intersections, the matched virtual intersection can be constructed according to different test scenes, the labor cost for the on-site test and the hardware cost of the multi-intersection access sensing equipment are saved, the requirement of the end-to-end forwarding link stability test between the intersections is met, and the flexibility of the end-to-end forwarding link stability test between the intersections can be improved. The virtual intersection test end simulates the real intersection, so that the transmission data of the link test at the real intersection side can be accurately simulated, the intersection type and the number of intersections for carrying out the link test are expanded, and the flexibility, the accuracy, the success rate and the test efficiency of the end-to-end forwarding link stability test between the intersections can be improved.
According to the method and the device for transmitting the link test, the link test transmitting data of the first intersection test end is obtained, so that the link test transmitting data are transmitted to the second intersection test end, the link test receiving data of the second intersection test end are obtained, and therefore intersection forwarding link test results of the first intersection test end and the second intersection test end are determined according to the link test transmitting data and the link test receiving data. Because the first intersection test end or the second intersection test end can be a virtual intersection test end, the end-to-end forwarding link stability test between intersections is completed by introducing the virtual intersection test end, the problems of low accuracy, success rate, low test efficiency and the like of the end-to-end forwarding link stability test between intersections in related technologies are solved, and the flexibility, accuracy, success rate and test efficiency of the end-to-end forwarding link stability test between intersections can be improved.
In an example, fig. 2 is a flowchart of a link testing method provided by an embodiment of the present disclosure, and the embodiment of the present disclosure provides various specific alternative implementations of obtaining link test sending data of a first intersection testing end, sending the link test sending data to a second intersection testing end, obtaining link test receiving data of the second intersection testing end, and determining intersection forwarding link test results of the first intersection testing end and the second intersection testing end on the basis of the technical solutions of the above embodiments.
In an optional embodiment of the disclosure, the first intersection test end is the virtual intersection test end, and the second intersection test end is a real intersection test end; the virtual intersection testing end comprises a first virtual intersection testing end and a second virtual intersection testing end; before obtaining the link test sending data of the first road port test end, the method may further include: obtaining geographical position information of a detected intersection of the real intersection testing end; determining a target test range of the geographic position information of the tested intersection; generating first test intersection geographic position information of the first virtual intersection test end and second test intersection geographic position information of the second virtual intersection test end according to the detected intersection geographic position information and the target test range; wherein, the geographical position information of the first test intersection belongs to the target test range; and the geographical position information of the second test intersection does not belong to the target test range.
The first virtual intersection testing end and the second virtual intersection testing end can be two different types of virtual intersection testing ends. Optionally, the first virtual intersection testing end and the second virtual intersection testing end may be two different types of virtual intersection testing ends configured according to a link testing range. The geographical position information of the detected intersection can be the geographical position information of the real intersection testing end. The target test range may be a distance range that the real intersection test end needs to test. The first test intersection geographic location information may be geographic location information where the first virtual intersection test end is located. The geographic location information of the second test intersection may be geographic location information of the second virtual intersection test end.
In order to realize the comparison test of the stability of the end-to-end forwarding links between the intersections, the effectiveness of the stability test of the end-to-end forwarding links between the intersections is improved, and the stability test of the end-to-end forwarding links between the intersections can be carried out by introducing different types of virtual intersection test ends to match with real intersection test ends. The first virtual intersection testing end can be a virtual intersection testing end within the testing range of the real intersection testing end; the second virtual intersection test end may be a virtual intersection test end outside the test range of the real intersection test end.
Specifically, the real intersection test end can be used as the second intersection test end, and the geographic position information of the real intersection test end is obtained as the geographic position information of the detected intersection. Further, a target test range can be determined according to the geographic position information of the tested intersection, and the geographic position information of the first test intersection of the first virtual intersection test end and the geographic position information of the second test intersection of the second virtual intersection test end are generated according to the geographic position information of the tested intersection and the configured target test range. For example, assuming that the target test range is configured to be 500 meters, the first test intersection geographic position information of the first virtual intersection test end may be any geographic position information with the geographic position information of the tested intersection as the center and the radius within 500 meters; the second test intersection geographic position information of the second virtual intersection test end can be any geographic position information with the geographic position information of the tested intersection as the center and the radius being 500 meters.
After two different types of virtual intersection test ends are generated according to the target test range configuration, the two virtual intersection test ends can simulate a real intersection and a real intersection test end to perform link test. It can be understood that under normal conditions, the first virtual intersection testing end located in the geographical position information of the first testing intersection can interact with the real intersection testing end in normal link data. That is, the link test transmission data transmitted by the first virtual intersection test end can be normally forwarded to the real intersection test end. And the second virtual intersection test end positioned in the geographical position information of the second test intersection cannot normally interact with the real intersection test end in link data. That is, the link test transmission data transmitted by the second virtual intersection test end cannot be forwarded to the real intersection test end.
In an optional embodiment of the disclosure, before acquiring the link test transmission data of the first intersection test end, the method may further include: generating link test configuration data of a link test task in response to a link test task configuration instruction; the link test configuration data comprises link test task configuration data and link test sending configuration data.
The link test task configuration data may be related configuration data of the link test task, and may be used to generate link test sending data of a virtual intersection test end in the link test task, for example, an intersection event type included in the specified link test sending data. The link test transmission configuration data may be related configuration data for transmitting the link test transmission data, and may be used to determine a data transmission mode of the link test transmission data, for example, determine a transmission frequency and a transmission duration of the link test transmission data.
Because the virtual intersection test terminal is the test terminal generated by configuration, the virtual intersection test terminal needs to be configured with link test configuration data so as to configure the virtual intersection test terminal through the link test configuration data, so that the virtual intersection test terminal can have the functions of data transmission, data reception and the like of the real intersection test terminal, and the real intersection test terminal is effectively simulated to participate in the link test. Alternatively, the link test configuration data may include, but is not limited to, link test task configuration data and link test transmission configuration data. Different types of link test configuration data may be used to configure different functions of the virtual intersection test end, which is not limited by the embodiments of the present disclosure.
A method of link testing as shown in fig. 2, comprising:
s210, responding to a link test instruction initiated by the first road port test end, and acquiring link test configuration data of the link test instruction.
The link test instruction may be an instruction initiated by the first intersection test end to start the link test.
In the embodiment of the disclosure, the first intersection test end can be set as a virtual intersection test end, the second intersection test end is set as a real intersection test end, and a link test instruction is initiated through the virtual intersection test end to send link test sending data to the real intersection test end. Optionally, the first intersection testing end in the embodiment of the present disclosure may include two virtual intersection testing ends, i.e., a first virtual intersection testing end and a second virtual intersection testing end. The two virtual intersection test terminals can respectively send link test sending data to the real intersection test terminals so as to synchronously carry out the link test. It can be understood that the link test flow between the two virtual intersection test ends and the real intersection test end can be independently performed without being affected by each other. After the first road port test end initiates the link test instruction, the link test system can acquire link test configuration data matched with the link test instruction so as to execute a subsequent link test flow according to the acquired link test configuration data.
S220, determining the link test task configuration data of the link test instruction according to the link test configuration data.
S230, generating link test sending data of the first road port test end according to the link test task configuration data.
Correspondingly, after the link test system acquires the link test configuration data, the link test configuration data can be analyzed to obtain link test task configuration data matched with the link test instruction, so that link test sending data of the first road port test end is determined according to the link test task configuration data.
According to the technical scheme, the link test sending data of the first intersection test end is generated according to the pre-configured link test task configuration data, flexible configuration of the virtual intersection test end can be achieved, the virtual intersection test end meeting any link test requirements is obtained, and flexibility and test efficiency of the end-to-end forwarding link stability test between intersections are improved.
Optionally, when the link test system is formed by the cloud control platform and the test server, or is formed by the cloud control platform, the test server and the link test service, the test server can simulate and generate two virtual intersection test ends as the first intersection test end to initiate the link test instruction, and the test server further generates link test sending data of the first intersection test end according to the link test task configuration data matched with the link test instruction.
When the link test system is only composed of the cloud control platform and the cloud control platform configures the function of the test server, the cloud control platform can simulate and generate two virtual intersection test ends as the first intersection test end to initiate a link test instruction, and the test server further generates link test sending data of the first intersection test end according to link test task configuration data matched with the link test instruction.
In an optional embodiment of the disclosure, the generating the link test transmission data of the first intersection test end according to the link test task configuration data may include: determining the first road port test end according to the link test task configuration data; acquiring link test sending configuration data of the first road port test end; determining a current intersection reporting event of the first intersection testing end according to the link testing sending configuration data of the first intersection testing end; and determining the current intersection reporting event as link test sending data of the first intersection test end.
The intersection reporting event may be a traffic event reported by an intersection testing end device (such as RSCU device). The current intersection reporting event may be a traffic event currently reported by the first intersection testing end. The intersection reporting event can be configured according to the real intersection traffic condition, and exemplary intersection reporting events can include, but are not limited to, various traffic events such as traffic jams, motor vehicle reverse running, motor vehicle overspeed, road construction, traffic accidents, red light running of pedestrians, road occupation and the like.
Specifically, the link test system may determine the first intersection test end according to the link test task configuration data, for example, may determine the first virtual intersection test end within the target test range and the second virtual intersection test end outside the target test range according to the target test range of the link test task configuration data as the first intersection test end. After the first road port testing end is determined, link test sending configuration data of the first road port testing end can be further obtained. Optionally, the link test sending configuration data may determine the type and the reporting mode of the intersection reporting event that each virtual intersection test end may report. Therefore, the link test system can determine the current intersection reporting event of the first intersection test end according to the link test sending configuration data of the first intersection test end, and determine the current intersection reporting event as the link test sending data of the first intersection test end. It can be understood that the current intersection reporting event of the first virtual intersection testing end and the current intersection reporting event of the second virtual intersection testing end can be the same or different; the reporting manner of the current intersection reporting event of the first virtual intersection testing end and the reporting manner of the current intersection reporting event of the second virtual intersection testing end can be the same or different, and the embodiment of the disclosure does not limit the reporting manner.
Taking the first virtual intersection test end as an example, the link test system can send configuration data according to the link test matched with the first virtual intersection test end, and randomly select an intersection reporting event which can be reported by the first virtual intersection test end as a current intersection reporting event of the first virtual intersection test end. Or, the link test system may further determine a reporting sequence of each intersection reporting event according to the link test sending configuration data matched with the first virtual intersection test end, and sequentially select, according to the reporting sequence of each intersection reporting event, an intersection reporting event that the first virtual intersection test end may report as a current intersection reporting event of the first virtual intersection test end.
According to the technical scheme, the link test sending data of the first intersection testing end is determined by utilizing the link test sending configuration data of the first intersection testing end to determine the current intersection reporting event, so that the function of reporting traffic events of the real intersection testing end can be effectively simulated, and the accuracy and success rate of the end-to-end forwarding link stability test between intersections are improved.
S240, obtaining the link test configuration data of the link test instruction.
S250, determining the link test sending configuration data of the link test sending data according to the link test configuration data.
And S260, transmitting the link test transmitting data to the second intersection testing end according to the link test transmitting configuration data.
In the embodiment of the disclosure, after the link test system obtains the link test sending data of the first intersection test end, the link test sending data of the first intersection test end needs to be forwarded to the second intersection test end. Specifically, the link test system may obtain link test configuration data that is matched with the link test instruction initiated by the first port test end, so as to further determine link test transmission configuration data of the link test transmission data according to the link test configuration data. After the link test sending configuration data is obtained, a sending mode of the link test sending configuration data can be determined according to the configuration information of the link test sending configuration data, and the link test sending data is sent to the second intersection testing end according to the sending mode of the link test sending configuration data.
Therefore, the first intersection test end generates link test transmission data by simulating the real intersection test end, and transmits the link test transmission data to the second intersection test end according to a pre-configured data transmission mode, so that the requirements of end-to-end forwarding link stability tests among intersections in a plurality of different scenes are met.
In an optional embodiment of the disclosure, the sending the link test sending data to the second intersection testing end according to the link test sending configuration data may include: determining a data transmission range, a data transmission frequency and a data transmission duration of the link test transmission data according to the link test transmission configuration data; and transmitting the link test transmission data to the second intersection test end in the data transmission range according to the data transmission frequency and the data transmission duration.
The data transmission range may be a range in which link test transmission data can be transmitted. Optionally, the data transmission range may be determined according to a target test range of the real intersection test end. The data transmission frequency may be a frequency at which the first port test terminal transmits link test transmission data. The data transmission duration may be a duration of the first intersection testing end transmitting the link test transmission data.
Specifically, the link test system may specify a data transmission range, a data transmission frequency and a data transmission duration of the link test transmission data according to the link test transmission configuration data, so that the link test transmission data is transmitted to the cloud control platform according to the specified data transmission frequency and the specified data transmission duration, and the cloud control platform forwards the received link test transmission data to a second intersection test end in the data transmission range, thereby completing the whole link forwarding logic. For example, when the data transmission range is 500 meters, the cloud control platform forwards the received link test transmission data to all intersection test ends within 500 meters from the first intersection test end.
It can be understood that the intersection report event sent by the first intersection testing end can include two types of transient event and long-term event. Wherein, the transient event is a traffic event which happens briefly, such as pedestrians or motor vehicles running red light, etc. Long events, i.e. traffic events that occur for a long time, such as traffic jams and road construction, etc. The transmission time of the instant event is short, so that the problems of reporting failure, missed detection or event expiration and the like possibly exist, and the problem of link test transmission data transmission failure is extremely easy to occur. The time for reporting the instantaneous event can be regulated for the time for transmitting the instantaneous event configuration data, so that the continuous transmission of the reported instantaneous event is realized, and the accuracy, the efficiency and the detectability of the instantaneous event transmission are ensured. Long event transmission times are long and thus there may be a problem of redundancy of transmitted data. The long-time event configuration data is sent for a long time, and the reporting time of the long-time event can be regulated, so that the long-time event can be accurately sent and reported, and the accuracy of long-time event sending and the processing efficiency of the long-time event are ensured. Meanwhile, the data transmission range and the data transmission frequency of the intersection reporting event are appointed, so that the intersection reporting event can be transmitted to a specified real intersection testing end according to specific link testing requirements, and the efficiency and the accuracy of the link testing are improved.
In an optional embodiment of the disclosure, the sending the link test sending data to the second intersection testing end may further include: determining target link test transmission data according to each link test transmission data under the condition that the data types of the link test transmission data are the same data types and the data identifiers of the link test transmission data are different data identifiers; and sending the target link test sending data to the second intersection test end.
The target link test sending data may be link test sending data finally sent to the second intersection test end.
In the embodiment of the disclosure, the cloud control platform of the link test system may execute forwarding logic according to the aggregation logic. The method is specifically described by taking the event reported by the intersection as the link test sending data. The virtual intersection test end can send an intersection report event to the second intersection test end in the data sending range according to the data sending frequency and the data sending time length. Therefore, the event reported by the same intersection may need to be sent multiple times, and for one type of event, the cloud control platform only needs to forward to the second intersection testing end once. The virtual intersection test terminal can configure different data identifiers aiming at the same intersection reporting event so as to identify each intersection reporting event which is sent and reported. When the data types of the link test sending data received by the cloud control platform are the same data types and the data identifiers of the link test sending data are different data identifiers, the target link test sending data can be determined according to the link test sending data, so that the screened target link test sending data are sent to the second intersection testing end.
The virtual intersection test terminal is assumed to continuously send multiple times aiming at the same traffic congestion event, the data identifiers of the virtual intersection test terminal are respectively a traffic congestion event 1, a traffic congestion event 2 and a traffic congestion event 3, the 3 traffic congestion events are actually the same traffic congestion event, and after the cloud control platform receives the traffic congestion event 1, the traffic congestion event 2 and the traffic congestion event 3, one of the traffic congestion events can be selected from the traffic congestion events, for example, the last received traffic congestion event 3 is selected as target link test sending data according to the data receiving sequence, and the traffic congestion event 3 is only forwarded to the second intersection test terminal.
According to the technical scheme, the configured aggregation logic is used for transmitting the target link test transmission data to the second intersection test end, so that the second intersection test end can be prevented from transmitting redundant data, and the link test efficiency is improved.
S270, acquiring link test receiving data of the second intersection test end.
In an optional embodiment of the disclosure, the second intersection testing end is a real intersection testing end; the obtaining the link test receiving data of the second intersection test end may include: acquiring a data forwarding log of the real intersection test end; taking the data forwarding log as link test receiving data of the real intersection test end; or acquiring terminal receiving data of a mobile terminal in communication connection with the real intersection testing terminal; and taking the terminal receiving data as the link test receiving data of the real intersection test terminal.
The data forwarding log may be a data log forwarded by a virtual intersection testing end received by the real intersection testing end. Alternatively, the data log may be an intersection report event log. The terminal receiving data can be data forwarded by a virtual intersection testing end received by a mobile terminal in communication connection with the real intersection testing end. Alternatively, the mobile terminal in communication connection with the real intersection testing terminal may be, for example, a vehicle-mounted terminal or the like.
In the embodiment of the disclosure, the link test system may obtain the link test receiving data of the second intersection test end, that is, the real intersection test end, in a plurality of ways. Optionally, when the link test system configures the link test service, the link test system may directly obtain the data forwarding log of the real intersection test end through the link test service. For example, the service of the real intersection testing end can be logged in through the link testing service to check and acquire the data forwarding log generated by the real intersection testing end. If the service logging in the real intersection testing end checks and acquires the data forwarding log generated by the real intersection testing end, the forwarding monitoring script can be configured at the real intersection testing end. The forwarding monitoring script can randomly grab the log of the reporting event of the virtual intersection test terminal forwarding intersection at the real intersection test terminal as a data forwarding log, and forward the acquired data forwarding log to the link test service through a callback interface. Correspondingly, the link test service can take the obtained data forwarding log as link test receiving data of the real intersection test end.
If the communication capability between the vehicle end and the intersection is further tested, a real vehicle can be placed at the real intersection testing end, and the vehicle-mounted terminal of the real vehicle receives the data forwarding log forwarded by the virtual intersection testing end. Or, the mobile terminal and the real intersection test terminal can be connected in a communication way, and the data forwarding log forwarded by the virtual intersection test terminal is received in a mode that the mobile terminal simulates the vehicle-mounted terminal. After the data forwarding log is obtained through the terminal, the data forwarding log can be used as terminal receiving data, and the terminal receiving data is used as link test receiving data of a real intersection test terminal. Accordingly, the link test service may further receive link test reception data transmitted from the mobile terminal.
After the link test service obtains the link test sending data and the link test receiving data, the intersection forwarding link test results of the first intersection test end and the second intersection test end can be determined according to the link test sending data and the link test receiving data.
Optionally, if the link test system is only formed by the cloud control platform, the link test receiving data may be received by the cloud control platform and the intersection forwarding link test results of the first intersection test end and the second intersection test end are determined according to the link test sending data and the link test receiving data. If the link test system is composed of the cloud control platform and the test server, the link test receiving data can be received by the cloud control platform or the test server so as to determine the intersection forwarding link test results of the first intersection test end and the second intersection test end according to the received link test sending data and the link test receiving data.
According to the technical scheme, the link test receiving data of the second intersection test end are obtained through a plurality of different modes, so that the implementation modes of the link test are enriched, and the flexibility of the link test is improved.
S280, comparing the link test sending data with the link test receiving data to obtain a sending and receiving data comparison result.
S290, determining the intersection forwarding link test results of the first intersection test end and the second intersection test end according to the comparison result of the sending and receiving data.
The comparison result of the sending and receiving data may be a comparison check result of the link test sending data and the link test receiving data.
In the embodiment of the disclosure, after the link test system obtains the link test sending data and the link test receiving data, the link test sending data and the link test receiving data can be compared and checked to obtain the sending and receiving data comparison result, so that the final intersection forwarding link test results of the first intersection test end and the second intersection test end are determined according to the sending and receiving data comparison result.
By way of example, assuming that both link test transmit data and link test receive data are traffic congestion events, the stability of the end-to-end forwarding link between intersections may be considered to pass the test. Assuming that the link test sending data is a pedestrian red light running event and the link test receiving data is an empty or motor vehicle red light running event, indicating that the link test sending data and the link test receiving data are not unified, the stability of the end-to-end forwarding link between intersections can be considered to be failed in the test.
According to the technical scheme, the different virtual intersection test ends are configured to send the link test sending data to the real intersection test end, and the final intersection forwarding link test results of the first intersection test end and the second intersection test end are determined based on the link test receiving data of the second intersection test end, so that the flexibility, the accuracy, the success rate and the test efficiency of the end-to-end forwarding link stability test between intersections are improved.

Fig. 4 is a schematic structural diagram of a link test based on the link test system according to an embodiment of the present disclosure. In a specific example, as shown in fig. 4, the cloud control platform may be composed of different systems such as a cloud control front end, a cloud control back end service, and intelligent cloud access. The cloud control front end may have a manual configuration function, and fig. 5 is an effect schematic diagram of a cloud control front end configuration interface provided by the embodiment of the present disclosure, as shown in fig. 5, the cloud control front end may configure a corresponding virtual intersection, an event reported by the virtual intersection, and an event broadcasting range according to a real intersection. For example, the cloud control front end can configure a virtual intersection with a distance of 0 meter and an event broadcasting range of 0 meter according to the real intersection 1, so that the virtual intersection is overlapped with the real intersection 1, and the virtual intersection can call a related interface of the real intersection 1 to acquire information sent by the road test sensing equipment of the real intersection 1. Therefore, if the virtual intersection configured at the cloud control front end can perform data interaction with the drive test sensing equipment of the real intersection, the virtual intersection is actually configured as the real intersection. If the virtual intersection configured at the cloud control front end cannot interact with the drive test sensing equipment of the real intersection, the virtual intersection is actually configured as the virtual intersection, and the virtual intersection is actually a static intersection and cannot interact with other intersections. The virtual intersection test end belongs to a dynamic intersection, and can simulate a real intersection to perform data interaction with other intersections.
Considering that the commercial delivered environment prohibits similar end-to-end testing by simulating the reporting of the false data event, the embodiment of the disclosure creates a test server for realizing the creation of the virtual intersection and simulating the reporting of the false data event by the created virtual intersection, thereby meeting the end-to-end testing requirements of various event broadcasting ranges.
In the embodiment of the disclosure, optionally, the test server may interact with the cloud control platform to complete the creation of the virtual intersection test end together. Specifically, an event broadcasting range may be manually configured at the cloud control front end of the cloud control platform, where the optional range includes 0 meter (not broadcasting), 300 meters, 500 meters, 1000 meters, 1500 meters, 2000 meters, and the like, and the event broadcasting range may be set according to actual requirements, which is not limited by the embodiments of the present disclosure. When the virtual intersection test end is created, the cloud control platform can acquire the longitude and latitude of the RSCU1 of the real intersection test end, for example: longitude 105.9416097; latitudes 29.3593911. Assuming that the event broadcasting range configured by the cloud control front end is 500 meters, the equipment maintenance management function of the cloud control platform can generate a virtual intersection road2+ sensing equipment RSCU2 equipment as a virtual intersection test end, for example, longitude and latitude information of the virtual intersection test end can be longitude 105.9416091; and latitude 29.3593913. The virtual intersection test end can be in the broadcasting range of the selected real intersection test end through two-point longitude and latitude calculation. Meanwhile, the cloud control platform can also generate another virtual intersection 'road 3+ sensing device RSCU 3' which is not in the event broadcasting range of the selected real intersection test end as the virtual intersection test end, for example, longitude and latitude information of the virtual intersection test end can be longitude 105.9496097; and latitude 29.7593911. The two virtual intersection test ends can interact with the real intersection test ends respectively to perform comparison test.
Correspondingly, the test server can perform data interaction with the cloud control front end through an interface so as to acquire information configured by the cloud control front end. The test server can generate a virtual intersection test end capable of simulating reporting of a false data event according to the manual configuration information acquired from the cloud control front end, and the geographic position information of the virtual intersection test end can not be the geographic position information of a certain real intersection. Fig. 6 is an effect schematic diagram of an end-to-end broadcast test configuration interface in a test server according to an embodiment of the disclosure. In a specific example, as shown in fig. 6, a virtual intersection test end can be created in a test platform provided by a test server by opening a configuration interface for end-to-end broadcast testing. In the interface of the end-to-end broadcast test, after the user triggers the new test task, the test server may access the information configured by the cloud control front end through the interface to determine relevant information of the real intersection test end, for example, the relevant information may include a city where the real intersection is located (shown as Guangzhou test in fig. 6, for example), a name of the real intersection (shown as 9 in fig. 6, for example), a real RSCU on the side of the real intersection, and the like (shown as BFD123353452 in fig. 6, for example). Meanwhile, the test server may also determine relevant information of the virtual intersection test end by accessing information configured by the cloud control front end through the interface, for example, may include a broadcasting range of an event reported by the virtual intersection test end (shown as 1000 meters in fig. 6 by way of example), and virtual RSCU at the virtual intersection side (shown as testQaRscu1 and testQaRscu2 in fig. 6 by way of example). That is, the test server can automatically acquire and configure the relevant configuration information of the virtual intersection test end and the real intersection test end without manual one-to-one configuration.
On this basis, as shown in fig. 6, the test server may also configure the type of forwarding event (i.e. reporting event) for the virtual intersection test end. Alternatively, the user may select a plurality of forwarding events from the forwarding event list for testing. If the user does not select, the test server may default to testing all forwarding events included in the forwarding event list.
Fig. 7 is an effect schematic diagram of a drive test concurrency data configuration interface in a test server according to an embodiment of the disclosure. In a specific example, as shown in fig. 7, the test server may further configure the attribute of the event reported by the virtual intersection test end through the drive test concurrency data configuration interface. Specifically, the test server can determine an event list which can be reported by the virtual intersection test end through the drive test concurrency data configuration interface, and set the concurrency quantity of reported events through setting process data. On the basis, the test server can also configure the related information such as the event distance, the frequency, the duration and the like of each reported event. After the test server completes the configuration of the virtual intersection test end, the user can trigger the click generation function in the newly-built forwarding test task through the configuration interface of the end-to-end broadcast test shown in fig. 6, and the test server can automatically generate a test task. Further, the user triggers the "running" function of the test task in the configuration interface of the end-to-end broadcast test, so that the whole link test system can start to automatically perform the end-to-end link test flow according to the configured virtual intersection test end and the selected real intersection test end.
As shown in fig. 4, the test server may also configure a concurrent event tool for sending a report event of the virtual intersection test end. The concurrency event tool can be constructed by adopting JSON (JavaScript Object Notation ) and can complete the functions of constructing data, transmitting data, interfacing interfaces and the like based on an MQTT (Message Queuing Telemetry Transport, message queue telemetry transmission) protocol. The concurrency event tool can also convert data to be transmitted into PB structure type for asynchronous transmission, and can transmit according to aggregation logic according to fixed frequency of data configuration to be transmitted during transmission. Alternatively, the two created virtual intersection test ends may be tested in parallel or in series, which is not limited by the embodiments of the present disclosure.
The event reported by the virtual RSCU at the virtual intersection test end is processed by the cloud control forwarding logic, and if the broadcasting range of the event is 500 meters, the event is forwarded to all RSCUs (including RSCU1 of a real intersection possibly) within the 500 meter range of the virtual RSCU.
Further, in order to test the forwarding logic of the sensing device RSCU, the real intersection RSCU1 may be directly logged in through a link test service device (not shown in fig. 4) to view the forwarded event log. If the communication capability of the vehicle end and the road is further tested, a real vehicle can be placed at the real road junction, the event message forwarded by the virtual road junction sensing equipment is received at the vehicle end terminal, and the event message received by the vehicle end terminal is sent to the link test service equipment. The link test service equipment can compare and check according to the event information reported by the virtual intersection test end and the event information received by the real intersection test end so as to determine the intersection forwarding link test result between the two intersection test ends.
If log-in checking is complicated, a forwarding monitoring script can be configured on the real RSCU1 so as to capture the log of the forwarding event at any time. If the link test report is captured, forwarding the captured event log to a test server through a callback interface so as to generate the link test report through the test server, wherein the link test report can comprise an intersection forwarding link test result between two intersection test ends.
As shown in FIG. 4, the real intersection test end may be a calculation unit RSCU1, RSCU2 may be a virtual intersection test end within the RSCU1 test range, and RSCU3 may be a virtual intersection test end outside the RSCU1 test range. In an actual scenario, the RSCU1 may receive data sent by a Road Side Unit (Road Side Unit) and a Road Side sensing device. The reported event, the obstacle information and the related information of the equipment can be sent to the cloud control platform intelligent cloud access platform based on the mqtt link and sent to the back-end service for processing through the intelligent cloud access platform. The related data of the red light can be processed based on the back-end service of the HTTP (HyperText Transfer Protocol ) cloud control platform. The link test system can be connected with a real intersection test end and also can be connected with a vehicle end terminal through the real intersection test end, so that a complete link test flow is realized. The vehicle terminal can transmit relevant data of the vehicle terminal to the rear end service of the cloud control platform for processing through a Mass (an infrastructure) platform.
Reporting events are respectively carried out on RSCU2 in the test range and RSCU3 not in the test range, and then corresponding forwarding log comparison experiments are checked at the vehicle end or sensing equipment of the real intersection, so that whether forwarding logic of the cloud control platform is correct or not is verified.
Optionally, the above-mentioned manual configuration event scope, concurrent event tool, forwarding monitoring script, callback interface and other functions can be automatically configured on the test server, the front end can be used for the test personnel to manually configure the event scope, the event type and sending frequency of mock (generating random data), and the rear end execute the above-mentioned series of automatic logic, thus completing the test of the end-to-end event broadcast on the RSCU side. The automatic configuration of the test server can be realized by calling a cloud control platform interface and a callback interface monitored by a real intersection test end.
Therefore, through configuring an event broadcasting range, dynamically generating two virtual intersection testing ends (one is within the broadcasting range, one is outside the broadcasting range), pushing various events supported by road sides to the two virtual intersection testing ends in a time-sharing period (up to 16 or more), simultaneously configuring a forwarding monitoring script at a real intersection testing end to receive the events forwarded by the virtual intersection testing end, and returning the events to a testing server, all the functions are realized through a platform side, a front end display can be used for a tester to select the event broadcasting range, a rear end logic executes the manual operation, the testing of the forwarding logic can be automatically realized through the testing server, and the flexibility, the intelligence and the testing efficiency of the stability testing of the forwarding links from end to end between intersections are improved.
It should be noted that any permutation and combination of the technical features in the above embodiments also belong to the protection scope of the present disclosure.
