A control device testing device and method based on vector words

Abstract

The invention discloses a control device testing device and method based on vector words. The device includes a man-machine interface, a main control module and a communication module; The control module generates a test command associated with the simulation platform, and the test command includes an instruction message representing the test function provided by the simulation platform; the instruction message and the query command are sent to the control device to be tested through the communication module, and the query command is configured to follow the set Query whether there is a vector word update on the communication bus at a fixed time period; when the vector word update is inquired, the communication module receives the response data generated by the control device under test after executing the command message sent by the control device through the communication bus; the main control module responds to Data is processed to generate test results; the invention can simulate different test platforms to perform different function and process tests on control equipment, and through vector word control, the reliability of communication test is high.

Description

technical field [0001] The invention belongs to the technical field of control equipment testing, and more specifically relates to a control equipment testing device and method based on vector words. Background technique [0002] The control equipment in shipborne, airborne, spaceborne and other weapons and equipment is mainly used to realize the output and backtest of control signals. It is one of the important components of the control system and is widely used in aviation, aerospace, ships and other fields; the existing The control equipment generally has the functions of multiple communication buses, multi-channel control signal output and multi-channel switch signal input, which can complete the functions of command transmission and information exchange. The control equipment is very important for the normal operation of weapons and equipment. Whether the hardware interface and software state of the product docking test or before delivery meet the state requirements for...

Problems solved by technology

[0003] At present, the control equipment has a variety of communication buses (CAN bus, 1553B bus), but it is mainly the 1553B bus when it is connected with the airborne platform. Communication interface, digital input and output interface and other hardware interfaces are working normally, and it is impossible to test whether the software status of the control equipment reaches the required state; second, it is not possible to simulate multiple platforms to test the control equipment; When testing, the main control module passively waits for the response of the control device after sending out the command. When the amount of test data is large, frame loss is likely to occur, and the reliability is insufficient.
