Description

Technical Field

[0001] The invention relates to an automatic testing system and method for radar products, belonging to the technical field of automatic testing. Background Art

[0002] For today's mass-produced models, product functions are becoming more and more complex, and the number of test items is increasing. The unit's darkroom resources and equipment resources are limited. How to complete product testing faster and better within a limited time poses a challenge to production support personnel.

[0003] When testing radar products using traditional methods, there are a series of problems such as many test items, complex test processes, and consistency evaluation of test results. Previously, product testing required at least three people to work together for three hours. When the schedule was tight, only a large number of people could be used. The equipment was in production 24 hours a day, which put a heavy burden on the testers and also increased the quality risk invisibly. Not only that, due to the different testers, the phenomenon of human factors affecting the test results always exists during the batch production of products, resulting in human factors affecting the consistency of product testing. In addition, the test result data is recorded by the testers in the test form, and the paper records are retained, which are easy to be lost during the storage process. Summary of the invention

[0004] The technical problem solved by the present invention is: to overcome the shortcomings of the prior art and propose an automatic testing system and method for radar products, which completes the indoor index test of radar products through automatic testing and outputs test data, thereby improving the test efficiency and reducing the investment in human resources.

[0021] Furthermore, the main control module can satisfy the requirement of performing a test on a certain test item separately according to user requirements, and directly derive key parameters of the test after the separate test item is finished by judging the preset value of the Boolean variable.

[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] The present invention proposes an automated test system for radar products, which is applied to the acceptance test of mass-produced models of radar products. The system adopts C++ to write programs and uses a test host compiled in the QT5.12 environment to interact with a forwarding signal source, a programmable power supply, and a product to be tested, and controls the completion of all test project processes, and further generates a test result data report, thereby realizing the automation of product testing, greatly saving manpower and material resources, and not only improving product production efficiency, but also providing strong support for product consistency analysis and ensuring product quality.

[0037] The automated test system mainly includes a test host, a program-controlled power supply, a forwarding signal source, a turntable, a target simulator and a speaker. The product to be tested, the turntable, the speaker and the target simulator are located indoors, and the rest of the equipment is located outdoors. The test host communicates with the program-controlled power supply, the forwarding signal source and the turntable via a serial port, and the test host communicates with the target simulator via an Ethernet port.

[0038] Test host: responsible for communicating with the product and other equipment in the test system, issuing test instructions, collecting test data and generating test reports, etc.

[0039] Programmable power supply: Receives commands from the test host to power on and off the product, and reports the current voltage and current values ​​for monitoring.

[0040] Forwarding signal source: receives commands from the test host, modulates and forwards the received signal, and reports information related to the received signal and the forwarded signal.

[0041] Turntable: Receives commands from the test host to position and rotate, and reports current position information.

[0042] Target simulator: receives commands from the test host to simulate target movement and report position information.

[0043] Speaker and test cable: receive and send signals.

[0044] During the test, the product to be tested is placed on a turntable. The signal is sent by the product, input to the forwarding signal source through the receiving speaker, forwarded to the speaker after modulation processing, and finally received by the product. After processing, it is sent to the test host to form test data. For the specific test environment, see Figure 1 .

[0045] As the hub of the entire test system, the test host plays a role like the brain in the system. The test host can be divided into two parts: hardware and software. The hardware includes communication serial ports, network ports and other devices; the software is written using multi-threaded programming technology. According to the functional modules, it can be roughly divided into the main control module, product data receiving module, product data processing and parsing data storage module, forwarding signal source communication control module, DC power supply communication control module, turntable communication control module, and test report generation module. The modules interact with each other using the mechanism of signals and slots. Among them, the main control module is responsible for interacting with the interface user, information display, and one-key test process control. The test process is divided into individual test items, and the code of each test item is encapsulated as an execution function. When performing a one-key test, all execution functions are run in series, and the one-key test ends when all are executed; according to user requirements, a test item can be tested separately, and the key parameters of this test can be directly introduced after the individual test item is completed by judging the preset value of the Boolean variable.

[0046] Specific test methods such as Figure 2 As shown, the following steps are included:

[0047] (1) First, control the DC power supply through serial communication, set its voltage limit and current limit, and power on the product.

[0048] (2) After the product is powered on, the signal source, turntable, target simulator and product are controlled based on the serial port and network port communication control, and the tests are performed one by one in the test sequence.

[0049] (3) When you need to call up the key test parameters of a test item, you can choose to perform automatic testing on this item only. After the test is completed, the key test parameters will be displayed.

[0050] (4) During the complete test, after the last item is tested, the test result data report will be generated to the specified path and the test will end.

[0051] The above-described embodiments are only preferred specific implementations of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
