Abstract
Description
Technical Field
[0001] This invention relates to the field of radar testing technology, and in particular to a radar module testing system, method, electronic device, and storage medium. Background Technology
[0002] In related technologies, after the radar module is installed in the main unit, functional testing is required. The conventional approach is to check whether the radar module's test data at specific angles and distances (N specific distances) meets expected values. This requires the tester to place the object under test (DUT) in a designated area before triggering the radar module to detect and provide test data, which the tester then records. When there are many DUTs, the tester needs to frequently move the DUTs and must also step outside the testing area during the test. This results in relatively low testing efficiency and cumbersome procedures for the tester. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a radar module testing system, method, electronic device and storage medium that can automatically and intelligently test radar modules, thereby improving efficiency.
[0004] The objective of this invention is achieved through the following technical solution: This application provides a radar module testing system, comprising: a host computer; a first driving device communicating with the host computer; a second driving device communicating with the host computer, wherein the first driving device is located on one side of the second driving device; a corner reflector disposed on the first driving device; and a radar module disposed on the second driving device, wherein the radar module communicates with the host computer. The host computer controls the first driving device to drive the corner reflector to move, and the host computer operates the second driving device to drive the radar module to move, thereby creating an angle and distance between the corner reflector and the radar module to complete the test.
[0005] The first driving device is a dual-axis robotic arm.
[0006] The second drive device is a turntable.
[0007] A test area is provided between the first drive device and the second drive device.
[0008] A second aspect of this application provides a radar module testing method, comprising: a host computer acquiring information on a test item, and driving a first driving device and a second device to move according to the test item information, thereby generating a test angle and a test distance between a corner reflector and a radar module, respectively. The host computer acquires the test data from the radar module based on the test angle and the test distance, compares the test data with a preset threshold, and outputs the test results.
[0009] A third aspect of this application provides an electronic device, comprising: Processor; and A memory that stores executable code, which, when executed by the processor, causes the processor to perform the method described above.
[0010] A fourth aspect of this application provides a computer-readable storage medium having executable code stored thereon, which, when executed by a processor of an electronic device, causes the processor to perform the method described above.
[0011] Compared with the prior art, the present invention has at least the following advantages: This application employs a host computer to control a first driving device, which in turn drives the corner reflector to move. Furthermore, it controls a second driving device, which in turn drives the radar module to move. This establishes an angle and distance between the corner reflector and the radar module, thus completing the test. The entire process is not only highly efficient, but the use of both the first and second driving devices also allows for greater precision in the movement of the corner reflector and radar module, thereby improving the accuracy of the test results.

[0012] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below.
[0013] Figure 1 This is a functional block diagram of a radar module testing system according to an embodiment of the present invention; Figure 2 This is a flowchart illustrating another embodiment of the radar module testing system according to one embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of an electronic device according to an embodiment of the present invention. Detailed Implementation
[0014] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.
[0015] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0016] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0017] After the radar module is installed in the main unit, functional testing is required. The standard procedure involves checking whether the radar module's test data at specific angles and distances (N specific distances) meets expected values. This requires the tester to place the object under test (DUT) in a designated area before triggering the radar module to detect and provide test data, which the tester then records. When there are many DUTs, the tester needs to frequently move the DUTs and must also step outside the testing area during the test. This results in relatively low testing efficiency and cumbersome procedures for the tester.
[0018] To address the aforementioned issues, embodiments of this application provide a radar module testing system, method, electronic device, and storage medium, which can employ automated intelligent testing of radar modules, thereby improving efficiency.
[0019] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0020] Figure 1 This is a schematic flowchart of a radar module testing system shown in an embodiment of this application.
[0021] See Figure 1A radar module testing system includes: a host computer, a first driving device, a second driving device, a corner reflector, and a radar module; the first driving device communicates with the host computer, the second driving device also communicates with the host computer, and the first driving device is located on one side of the second driving device; the corner reflector is disposed on the first driving device; the radar module is disposed on the second driving device and communicates with the host computer; the host computer controls the first driving device to drive the corner reflector to move, and the host computer drives the second driving device to drive the radar module to move, thereby creating an angle and distance between the corner reflector and the radar module to complete the test.
[0022] It should be noted that the first drive device is a dual-axis robotic arm, the second drive device is a turntable, the radar module is usually mounted on the main unit, and the corner reflector is used to simulate a human. The host computer opens the testing software and then iterates through all preset test items. Next, the host computer communicates with the turntable, dual-axis robotic arm, and radar module. After communication is complete, the host computer loads the test item information, such as the overall unit angle, corner reflector angle, corner reflector distance, and threshold values for each indicator. Based on the current test item's overall unit angle, corner reflector angle, and corner reflector distance, the host computer controls the movement of the dual-axis robotic arm and turntable, and then starts the test. The host computer parses the radar module's test data to determine if it is within the threshold values. If so, the radar module is considered functionally qualified, and the test data is imported locally.
[0023] Thus, this application employs a host computer to control the first driving device, thereby driving the corner reflector to move, and to control the second driving device, thereby driving the radar module to move. This establishes an angle and distance between the corner reflector and the radar module to complete the test. The entire process is not only highly efficient, but the use of the first and second driving devices also allows for higher precision in the movement of the corner reflector and radar module, thereby improving the accuracy of the test results.
[0024] See Figure 1 In one embodiment, a test area is provided between the first driving device and the second driving device.
[0025] Understandably, no personnel moved within the test area to ensure the accuracy of the test results.
[0026] Corresponding to the aforementioned application function implementation method embodiments, this application also provides a radar module testing method, electronic device, and corresponding embodiments.
[0027] Figure 2 This is a flowchart illustrating the method steps of a radar module testing method as shown in an embodiment of this application.
[0028] See Figure 2 A radar module testing method, comprising: Step S101: The host computer obtains the information of the test item and drives the first driving device and the second device to move according to the information of the test item, thereby generating a test angle and a test distance between the corner reflector and the radar module respectively.
[0029] It should be noted that the host computer opens the testing software and then iterates through all the information for the items to be tested. Next, the host computer communicates with the turntable, the dual-axis robotic arm, and the radar module. After communication is complete, the host computer loads the information for the items to be tested, such as the overall machine angle, corner reflector angle, corner reflector distance, and threshold values for each indicator. Based on the current overall machine angle, corner reflector angle, and corner reflector distance for the test item, the host computer controls the movement of the dual-axis robotic arm and the turntable, and then starts the test.
[0030] Step S102: The host computer acquires the test data from the radar module based on the test angle and test distance, compares the test data with the preset threshold, and outputs the test results.
[0031] It should be noted that the host computer analyzes the test data of the radar module to determine whether it is within the threshold. If it is, it means that the radar module is functionally qualified, and the test data will be imported locally.
[0032] Regarding the system in the above embodiments, the specific ways in which each module performs operations have been described in detail in the embodiments related to the method, and will not be elaborated further here.
