General-purpose ground test equipment based on PLC module

Abstract

The invention discloses general-purpose ground test equipment based on a PLC module. The general-purpose ground test equipment comprises one or more PLC backboard modules, an input interface for leading out a signal of an external test interface of a PLC function extension module, and an output interface for leading out an output signal of the PLC function extension module, wherein a power supply module, a PLC main control module and the PLC function extension module are arranged on the PLC backboard module in a detachable manner; and the PLC function extension module at least comprises a PLC digital quantity output module, a PLC digital quantity input module, a PLC analog quantity output module and a PLC analog quantity input module. The ground test equipment disclosed by the invention has the characteristic of high resistance to adverse environment; besides, ladder logic programming language is used for programming and is simple and easy to change, so that multiple products can be tested through single test equipment, the weight and the mounting space of on-board equipment are reduced, besides, the reliability and operation requirements are met, and development costs of a missile weapon system are reduced while the service life of the test equipment is prolonged.

Description

technical field [0001] The present invention relates to ground testing equipment. More specifically, it relates to a generalized ground test equipment based on PLC modules. Background technique [0002] A missile weapon system consists of missiles, ground (airborne, ship or submarine) equipment, detection and targeting equipment, guidance systems, launch systems, and command, communication, and control systems. The missile is an independent working system composed of various facilities, equipment and systems that complete missile maintenance, missile launch preparation, detection and targeting, missile launching and guiding missiles to complete the combat mission of destroying targets, and assessment of missile attack effects. [0003] As an important maintenance guarantee equipment for missile weapons and equipment, ground testing equipment is a weapon system product with a large number, frequent use, and complex working environment. Its production quality and test functio...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a ground test equipment with general functions, good expansibility and high reliability, which can be quickly configured according to different tested products to realize the function of testing multiple products by one test equipment. At the same time, the service life reduces the development cost of the missile weapon system, improves the comprehensive support efficiency of the grass-roots magazine, and is used to solve the problems of specialization of ground test equipment, resource duplication, poor scalability and low reliability in the past
