A Quick Calibration Device for 1553b Bus Type Servo System Test Equipment

Abstract

The invention relates to a quick check device for a 1553B bus type servo system test device. The quick check device carries interaction with the test device by an analog cable and a 1553B bus; the test device sends an instruction signal to the quick check device by the 1553B bus; the quick check device receives the signal from the external test device by means of transformer coupling, analyzes the signal into an analog quantity and outputs the analog quantity to a signal high end of a corresponding socket. According to the quick check device, when the 1553B bus type servo system test device is used in field, integrity of the test function and the test precision are detected in advance and the check work of signal sending and signal collection functions of the test device is completed; the quick check device detects the electrical performance and software protocol of the test device, so that the efficiency of product development, debugging and field test fault detection is improved.

Description

technical field [0001] The invention relates to a quick calibration device for 1553B bus type servo system testing equipment, which belongs to the technical field of servo system testing. Background technique [0002] 1553B bus type servo system test equipment is an automatic test equipment based on network and digital bus technology. It is a complex test system composed of computer, power supply box, transfer box and cables. Complete the sending of the control signal and the collection of the response signal of the remote terminal of the 1553B bus. After the analog signal is adjusted through the signal transfer box, it enters the analog signal acquisition card for collection and processing. At the same time, it completes the output of the 1553B bus control signal and the collection of data. Receive decoding and management, data processing, image display. [0003] 1553B bus test equipment has been widely used in the field of servo system testing. In the existing technology...

AI Technical Summary

Problems solved by technology

In the existing technology, the design and debugging of 1553B bus-type test equipment can only verify the correctness and reliability of bus communication through the final system joint test. This kind of verification can only prove whether the product meets the design requirements in terms of function, and cannot quantify the design. In the development process, electrical or protocol faults of system terminals and cables cannot be found at the first time, and EMC characteristic indicators of the network cannot be captured

When the 1553B bus-type test equipment fails, the test equipment designers and users often fall into a situation where there is nothing to do. They can only check the electrical performance with the help of traditional equipment (such as oscilloscopes, multimeters, etc.), which is inefficient, complicated to operate, and poor in reliability.

In addition, the integrity of its test function and test accuracy was not detected in advance when it was used in the field. If the test equipment fails, it will not be able to judge in time whether it is a test equipment failure or a product failure, which will delay the overall progress of the test.
