A plc-based multi-test bench using extrusion medium supply control system and method

Abstract

A PLC-based multi-test bench uses an extrusion medium supply control system and method. By adding a PLC control system locally between containers, local control and remote control of cryogenic containers can be realized, and local HMI can be used to realize the local extrusion supply system. Control and independently monitor vessel parameters. Remote control mode, each test bench and container communicate via Ethernet to monitor the state between containers in real time, each test bench is independent of each other, and has priority for the control between containers, which can effectively avoid the confusion of container control, and monitor the online status between containers It can also be displayed to the operators of each test bench in time to facilitate the orderly conduct of each test.

Description

technical field [0001] The invention relates to a PLC-based multi-test-bed using extrusion medium supply control system and method, belonging to the field of low temperature medium application. Background technique [0002] In the liquid rocket engine ground component test, the system that transports the cryogenic container medium to each test bench or station as required is called the medium supply system. Generally divided into extrusion type supply system and pump type supply system. [0003] For the extrusion supply system, by applying high-pressure gas to the low-temperature container, the low-temperature medium of the container is squeezed to each demand test bench, so as to realize the demand of each test bench for the medium and medium pressure. Usually, the operation of the cryogenic container includes filling, pressurizing, exhausting and feeding the medium, which are controlled by the electromagnetic valve. Filling is adding low-temperature medium from the low-te...
