Description

Technical Field

[0001] The invention relates to the technical field of intelligent testing, in particular to an intelligent matrix testing system. Background Art

[0002] TR components are an important part of active phased array radars and are the key to achieving and ensuring the performance of the entire system. A phased array radar may contain hundreds or even thousands of TR components. How to quickly and efficiently complete large-scale performance testing and inspection of components is crucial to the research and development, production and maintenance of phased array radar systems.

[0003] However, the TR component testing in the current market has a limited number of test instruments, and testers are faced with the cumbersome process of frequent wiring and disconnection, which leads to low test efficiency and higher risk of personnel fatigue. In addition, manual operation easily leads to inaccurate test results, making it difficult to achieve quality traceability of batch products, thus affecting the overall quality management and market competitiveness of the product. In view of the above problems, the inventor proposes an intelligent matrix testing system to solve the above problems. Summary of the invention

Except for the wiring of the TR component to be tested, all other operations are completed on the terminal device (industrial computer). After the user completes the wiring of the TR component and completes the parameter setting on the industrial computer, the system automatically completes all tests and displays the test results on the industrial computer.

[0037] The phased array radar TR component test system mainly includes an industrial computer, an embedded control unit, a driver board, a multi-channel matrix switch, a signal source, and a spectrum analyzer. Through the coordinated use of a lower computer and a host computer, the test system can effectively realize the cascade of multiple matrix switches of multiple positions by means of Ethernet communication; the user only needs to complete the access of multiple TR components at one time, and use a signal source and a spectrum analyzer to complete the test of a few or dozens of TR components at one time.

[0040] Test mode and parameter setting: Set manual or automatic test mode on the host computer (industrial computer); in manual test mode, you can set the machine number to which the specific TR component to be tested is connected and the channel number of the matrix switch; in automatic mode, you can set the multi-machine cascade or single-machine test mode, and when multiple machines are cascaded, you can set the order of the machine cascade;

[0041] Lower computer action: The lower computer completes the automatic switching of the matrix switch under the command control of the upper computer and the control of the main control board, realizing the effective connection of the signal source, the TR component to be tested and the spectrum analyzer;

[0044] Example 1 - Manual test: After the system is powered on and self-checked, the position number of the lower machine that needs to communicate is set on the upper computer (industrial computer) display screen. After successful communication, the upper computer display screen displays relevant information about the successfully connected lower machine. The user selects the manual test mode, and the manual test selects position 1, channel 2 (set according to the actual position channel number of the TR component connected to the lower computer). The upper computer and the lower computer establish communication at position 1. The lower computer main control module controls the drive board to drive the matrix switch to automatically switch to channel 2. After the set delay time, the upper computer successfully reads the test result of the TR component to be tested on channel 2 of position 1. At this time, the test result is normal, so there is no abnormal result alarm. The specific process is as follows: Figure 4 As shown:

[0045] Example 2 - Automatic test: After the system is powered on and completes the self-test, the position number of the lower machine that needs to communicate is set on the upper computer (industrial computer) display screen. After the communication is successful, the upper computer display screen displays the relevant information of the successfully connected lower machine. The user selects the automatic test mode, selects the cascade mode and sets the cascade sequence 1-2. The upper computer completes the communication with the positions 1-2. The lower computer main control module first drives the driver board of the position 1 to complete the automatic switching of the 1-5 matrix switch channels. When switching to channel 6, the cascade of the positions 1 and 2 is realized. At this time, the embedded control module controls the driver board to complete the automatic switching of the 1-5 matrix switch channels of the position 2; during the automatic switching of the matrix switch, the upper computer completes the reading, display and abnormal judgment of the test results of the TR components to be tested in each channel, and saves the test results of the same batch in the form of tables and reports. The specific flow chart is as follows Figure 5 shown.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
