[0025] The features and exemplary embodiments of various aspects of the present application will be described below in detail, in order to make the purposes, technical solutions and advantages of the present application more clear. The following further describes the present application in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, but not to limit the present application. The present application can be implemented without some of these specific details by those skilled in the art. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

[0026] It should be noted that, in this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, an element defined by the phrase "comprising a... " does not exclude the existence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0027] As described in the background, the inventors find that with the development of intelligent transportation and vehicle networking technology, more and more urban demonstration areas and expressways begin to deploy cellular vehicle-to-everything (C-V2X) roadside equipment RSU based on cellular network. As a communication device, the roadside equipment RSU needs to work with the roadside perception device to send the information and state of the traffic participants to the vehicle. The roadside equipment RSU needs to be continuously detected to ensure normal device function in the construction acceptance stage and the running stage. Currently, the test of the roadside equipment RSU has laboratory consistency test, mainly for index test and protocol compliance test, which cannot combine the roadside equipment RSU with the roadside perception device for testing. Moreover, most of the test methods are real vehicle tests, which install the on board unit (OBU) on the vehicle and perform real vehicle tests through the actual vehicle. Although the real vehicle test can combine the roadside perception device with the roadside equipment RSU in the actual road environment, the real vehicle test needs high test cost and test cycle, and the test efficiency is low.

[0028] To solve the problems in the prior art, the embodiments of the present application provide a roadside equipment test method, device, system and computer readable storage medium. The test case is received, wherein the road feature information and the roadside perception information are included in the test case. In this way, some static parameter information can be completed in the initialization setting, and subsequent repeated setting is not needed, thereby reducing the work complexity of the test personnel, saving time, and enabling the second perception result to be obtained according to the road feature information and the roadside perception information, so as to understand the state information of the traffic participants. Therefore, the roadside equipment is tested by the data information in the test case, rather than in the actual application scenario, thereby improving the test efficiency and reducing the test cost.

[0029] The roadside equipment test system provided by the embodiments of the present application will be described below in combination with the drawings, specific embodiments and application scenarios.

[0030] Figure 1 is a structural schematic diagram of a roadside equipment test system provided by the embodiments of the present application, as shown in Figure 1 the roadside equipment test system specifically can include: a first device 101, a roadside equipment 102, and a second device 103.

[0031] In some embodiments, the first device 101 is connected with the roadside equipment 102 and includes a test industrial computer and a test computer.

[0032] The test industrial computer is provided with simulation test software, which is mainly used for simulating an edge cloud (Multi-access Edge Computing, MEC) or a central cloud platform in actual application, is connected with the roadside device 102, receives test case data sent by the test computer, then sends processed test case data to the roadside device 102, and simultaneously sends the processed data in the test case to the test computer, and the test case includes road feature information, roadside perception information and a first perception result. Specifically, as shown in Figure 4 Figure 4 is a detailed working schematic diagram of a test system of a roadside device provided by an embodiment of the present application. The test industrial computer includes a communication module, which can be a Transmission Control Protocol (TCP) or Internet Protocol Address (IP) module. The test industrial computer sends test cases to the roadside device 102 through the TCP / IP module. In addition, the test industrial computer also includes a data generation module, a 232 module and a data processing module. The data processing module mainly processes data information in the test case. The 232 module mainly realizes conversion of wired serial data transmission into Wireless Fidelity (WIFI) transmission. Different data transmission modes are realized by hardware. The data generation module mainly generates perception structured data after processing data information in the test case.

[0033] The test computer is mainly used for receiving test results sent by the second device 103, and is provided with test software. Specifically, as shown in Figure 4 The test computer includes a configuration module, a test case generation module, a test control and a data analysis module. The configuration module is used for configuring parameter information in the test case. The test case generation module can generate a test case through configuration. The test control can send the test case to the test industrial computer through a test interface protocol. The data analysis module is used for analyzing test results sent by the second device 103. In addition, the test software also has an analysis and comparison function, which verifies the test algorithm logic and application function of the roadside device.

[0034] The roadside device 102 includes a roadside device RSU, which is used for receiving processed test case data sent by the test industrial computer, processing the data through its own algorithm and logic, and sending related information of the data in the test case to the second device 103 through a (Request Signal Message, RSM) or (Signal Status Message, SSM) message, which can be air interface data.

[0035] ​The second device 103, connected with the roadside device 102, comprises a C-V2X receiving device, mainly used for simulating a vehicle OBU, receiving the air interface data sent by the roadside device 102, and not needing to send its own data externally. Specifically, as shown in Figure 4 The second device 103 comprises a radio frequency receiving module, used for receiving the air interface data sent by the roadside device 102, converting the air interface data into a baseband signal, and then converting the baseband signal into a digital signal, and sending the digital signal to a data processing module. In addition, the second device 103 further comprises a data processing module, a TCP / IP module, a power management module, a security management module and a positioning module. The data processing module is used for receiving the digital signal, extracting and analyzing the air interface data sent by the roadside device 102, wherein a data analysis algorithm unit is arranged to extract and analyze the air interface data, and send the processed air interface data to a test computer. The TCP / IP module is used for communication between the second device 103 and the test computer, and completes data transmission through a designed terminal control interface (TCI) interface, and sends the test result to the test computer. The power management module, the security management module and the positioning module are mainly used for ensuring the normal work of the second device 103.

[0036] Thus, by receiving the test case, the road feature information and the roadside perception information are included in the test case, so that some static parameter information can be completed in the initialization setting, and subsequent repeated setting is not needed, thereby reducing the work complexity of the test personnel, saving time, and enabling the road feature information and the roadside perception information to be analyzed to obtain the second perception result and understand the state information of the traffic participant, so that the roadside device is tested through the data information in the test case, rather than in an actual application scene, thereby improving the test efficiency and reducing the test cost.

[0037] Based on the above-mentioned Figure 1 The structure of the test system of the roadside device provided by the embodiment of the present application is shown in the figure.

[0038] Figure 2 The figure is a flowchart of the test method of the roadside device provided by the embodiment of the present application.

[0039] As shown in Figure 2 The method can comprise the following steps:

[0040] S210, receiving a test case, the test case comprising road feature information and roadside perception information;

[0041] S220, analyzing according to the road feature information and the roadside perception information to obtain a second perception result, the second perception result including at least one of a number of traffic participants, a size of the traffic participants, a moving speed of the traffic participants, and a position of the traffic participants.

[0042] In some embodiments, in S210, the test case includes road feature information, such as the number of lanes, the position of lanes, the direction of lanes, and traffic participant information, wherein the traffic participant information includes pedestrians, non-motor vehicles, motorcycles, small cars, large trucks, etc., and the feature data in the traffic participant information includes length, width, height, color, longitude, latitude, speed, heading angle, altitude, roadside perception device sensor type, etc., in addition, the traffic participant feature data also has a reserved field for further development of new parameter types, and the roadside perception information includes, for example, microwave radar signals, infrared sensor signals, laser radar signals, and camera image acquisition, etc., in addition, the test case also includes a first perception result, which includes the number of traffic participants, the size of the traffic participants, the moving speed of the traffic participants, and the position of the traffic participants.

[0043] As an example, the tester configures the parameters of the relevant information on the test software to generate a test case (Extensible Markup Language, XML) file as a fixed test case, which can be directly imported for testing next time, or some parameters in the test case can be changed according to the test to regenerate the test case XML file, and when starting the test, the tester imports the test case XML file, and the test computer sends the test case to the roadside device 102 through the specified TCI test interface of the test industrial computer and the roadside device 102, and the roadside device 102 receives the test case.

[0044] In some embodiments, in S220, according to the road feature information and the roadside perception information in the test case, the roadside device 102 analyzes and processes them to obtain a second perception result, wherein the second perception result includes the number of traffic participants, the size of the traffic participants, the moving speed of the traffic participants, and the position of the traffic participants.

[0045] In order to determine whether the analyzed second perception result is accurate and further determine the accuracy of the test result, another implementation manner of the test method of the roadside device is further provided in the embodiments of the present application, which is described in detail below.

[0046] As shown in Figure 3 The test method of the roadside device described above can further include the following steps S310-S340.

[0047] S310, receive a test case, the test case including road feature information and roadside perception information.

[0048] S320, analyze according to the road feature information and the roadside perception information, obtain a second perception result, the second perception result including at least one of the number of traffic participants, the size of traffic participants, the moving speed of traffic participants and the position of traffic participants.

[0049] S330, in the case where the second perception result matches the first perception result, determine that the test result is that the roadside device passes the test case.

[0050] In some embodiments, the number of traffic participants, the size of traffic participants, the moving speed of traffic participants and the position of traffic participants in the first perception result are actual information, the road feature information and the roadside perception information in the test case are analyzed by the algorithm and the logic processing of the roadside device 102 itself to obtain the second perception result, and the parameters in the second perception result and the first perception result are compared. If the parameters in the second perception result and the first perception result match, it can be determined that the test result matches the actual information, and then it is determined that the test result is that the roadside device 102 passes the test case.

[0051] S340, in the case where the second perception result does not match the first perception result, determine that the test result is that the roadside device fails to pass the test case.

[0052] In some embodiments, the number of traffic participants, the size of traffic participants, the moving speed of traffic participants and the position of traffic participants in the first perception result are actual information, the road feature information and the roadside perception information in the test case are analyzed by the algorithm and the logic processing of the roadside device 102 itself to obtain the second perception result, and the parameters in the second perception result and the first perception result are compared. If the parameters in the second perception result and the first perception result do not match, it can be determined that the test result does not match the actual information, and then it is determined that the test result is that the roadside device 102 cannot pass the test case.

[0053] As an example, in order to determine that the test result is that the roadside device passes the test case, the above S330 can specifically include:

[0054] Step 1, according to the data information of the traffic participants in the second perception result, obtain a coincidence value, the coincidence value being determined according to the number, size, moving speed and position of the traffic participants in the second perception result;

[0055] Step 2, in the case where the coincidence value is equal to a preset threshold value, determine that the test result is that the roadside device passes the test case, the preset threshold value being determined according to the first perception result.

[0056] In some embodiments, according to the data information of the traffic participants in the second perception result, a fitting value can be obtained, wherein the fitting value is determined by the number, size, moving speed and position of the traffic participants in the second perception result, the preset threshold is determined by the number, size, moving speed and position of the traffic participants in the first perception result, the first perception result is used as the actual information, and thus the fitting value is compared with the preset threshold. Only when the fitting value is equal to the preset threshold, it is determined that the test result is that the roadside device passes the test case.

[0057] As an example, for example, the number of traffic participants obtained in the second perception result is 5 cars and 2 motorcycles, and then it can be determined that the fitting value is 7. If the actual information in the first perception result is 5 cars and 2 motorcycles, the preset threshold is set to be 7, the fitting value is equal to the preset threshold at this time, and it is determined that the test result is that the roadside device passes the test case. If the actual information in the first perception result is 5 cars and 3 motorcycles, the preset threshold is set to be 8, the fitting value is not equal to the preset threshold at this time, and it is determined that the test result is that the roadside device does not pass the test case. In addition, the size, moving speed and position of the traffic participants also need to determine the respective fitting values, compare them, and accurately determine whether the test result is that the roadside device passes the test case. In the case of completing the test case, the next test case is entered. If there are multiple test cases, automatic testing can be performed.

[0058] S310 to S320 are the same as S210 to S220 in the above embodiment, and are not described in detail here for brevity.

[0060] The second perception result is sent to the second device, and the second device is a device for simulating a vehicle on-board unit OBU.
