Automatic test system and method for communication control devices

Abstract

The invention discloses an automatic test system and method for communication control devices. The system comprises a main control module, a communication module, an acquisition module, a power sourcemodule and a human-machine interface; the main control module simulates a control unit to electrify a control device, and thereafter, sends a power source back-test command, a communication detectioncommand, a DO (digital output) command, a DI (digital input) command, an AD acquisition command, a control command, a function test command and a position data command; power source back-test information, communication response data, DO detection data, DI data, AD acquisition data, control response data, functional test response data and GNSS position information are analyzed according to a preset communication protocol and are compared with main control module standard values; test results are fed back to the human-machine interface; and therefore, problems brought about by a condition thatan existing control system only has a single function and single interface can be solved, and the functions of a plurality of communication control devices can be tested. Since the main control module, the communication module, the acquisition module, the power source module, a switching quantity input and output module and the human-machine interface are integrated, the communication control devices can be automatically tested, and test efficiency is significantly improved.

Description

technical field [0001] The invention belongs to the field of control equipment testing, and in particular relates to an automatic testing system and method for communication control equipment. Background technique [0002] The communication 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; Some communication control equipment generally have functions such as multiple communication buses, multi-channel control signal output, multi-channel switch signal input, and voltage acquisition, etc., which can complete command transmission, information exchange, status acquisition of external equipment, and voltage monitoring. And other functions, communication control equipment plays a very important role in the normal operation of weapons and equipment, the...

Problems solved by technology

[0003] At present, because the communication control equipment has multiple communication buses (CAN bus, 1553B bus), multiple control signal output, multiple switch signal input, voltage quantity collection and position information collection and other functions, the existing test equipment has the following functions: Insufficient: single function, not universal; one test equipment can only test one communication bus, such as CAN bus test equipment CANNOE can only test the CAN bus communication status, so at least two kinds of bus testing are required for communication control equipment The test equipment tests the communication status of the CAN bus and the 1553B bus respectively; the existing test system has a single function and interface, one test equipment can only test one communication bus, and the interface on the test equipment can only meet the test of a single communication control equipment , but in most cases it is necessary to test the performance of multiple communication control devices at the same time, the existing test equipment is far from meeting the test requirements in the production and test environment, resulting in low test efficiency and even affecting the production capacity of the production line
