Remote control automatic gas supply system

Abstract

The invention relates to a remote control automatic gas supply system mainly applied in the ground process of a rocket engine test and supplying a stable gas source, comprising air, nitrogen or helium, to the ground process of the rocket engine test. Remote automatic control of the system is achieved on the premise of ensuring stable gas supply of the system. The system mainly comprises a remote control automatic gas supply system configuration, a field control system and a gas distribution table system. According to the remote control automatic gas supply system configuration, writing of an upper computer is mainly completed through the VxSCADA configuration of SUPCON on an industrial control computer; a collected data signal is uploaded to the upper computer, and a control instruction issent after data processing and data analyzing are conducted; the control instruction is transmitted to the field control system through a redundant optical fiber communication network; the field control system transmits the received instruction to electromagnetic valves, electric ball valves and electric pressure reducers on redundant gas supply pipelines on the gas distribution table system through a redundant controller; and therefore it is ensured that the remote control gas supply function, the remote control gas release function, the automatic switching function, the data state display function, the unattended operation function and the like are achieved.

Description

technical field [0001] The invention relates to a remote control automatic gas supply system which is applied in the ground test process of a rocket engine to provide a safe, stable and reliable gas supply source and realize remote automatic control of the gas supply system. Background technique [0002] At present, the automation degree of the gas supply system at the domestic rocket engine test site is insufficient, and most of the gas supply systems are still mainly operated manually. Meet the user's gas supply needs. As users have higher and higher requirements for pressure and cleanliness in the gas supply process, the characteristics of the gas supply system, such as high flexibility, long duration, and complicated procedures, are highlighted. If a system failure occurs, it still relies on manual labor. The mode of troubleshooting will increase the danger of operators at work, so a remote control automatic gas supply system is developed, which will greatly improve the...

As users have higher and higher requirements for pressure and cleanliness in the gas supply process, the characteristics of the gas supply system, such as high flexibility, long duration, and complicated procedures, are highlighted. If a system failure occurs, it still relies on manual labor. The mode of troubleshooting will increase the danger of operators at work, so a set of remote control automatic gas supply system will be developed, which will greatly improve the safety and work efficiency of on-site operators
