Abstract

A test-launch-control remote data transmission system is used for remote data communication in an aerospace test-launch-control system. The test-launch-control remote data transmission system comprises a front end and a rear end connected through optical fibers. The rear end is composed of a rear-end PLC (programmable logic controller) set, a central computer, a virtual display computer and a command input module. The rear-end PLC set allows remote communication with the front end, which is a test-launch-control front end, receives switching signals from the central computer and the command input module and feeds status information acquired by the rear-end PLC set back to the virtual display computer for displaying. The front end is composed of a front-end PLC set; on one hand, the front end is used for receiving control commands from the rear-end PLC set and controlling a test object to correspondingly run, on the other hand, the front end transmits the status information of the front-end PLC set to the rear-end PLC set. The front-end and rear-end PLC sets allow front-end and rear-end data transmission through establishing a controller link network.

Description

technical field [0001] The invention provides a long-distance data transmission system for measurement, launch and control, which belongs to the field of spaceflight measurement, launch and control. Background technique [0002] At present, in the field of aerospace measurement, launch and control, the measurement, launch and control system based on long-distance data transmission is widely used. This kind of measurement, launch and control system is divided into two parts, the front end and the back end, according to the location of the equipment. The front-end equipment of the measurement and control system is placed near the launch tower, which is used to convey the control instructions issued by the back-end of the measurement and control system to the object under test; the back-end equipment of the measurement and control system is placed in the remote control test room as the entire measurement and control system operations, command and control center. Usually, the f...
