Abstract

A LNG filling station intelligent control system disclosed by the present invention is characterized by comprising a gas dispenser control system, a PLC process control system, a gas alarm system, an alarm system, an emergency cut-off system, an instrument wind system and an industrial control computer, wherein the PLC process control system is in signal connection with the gas dispenser control system, the gas alarm system, the alarm system, the emergency cut-off system, the instrument wind system and the industrial control computer separately, and the industrial control computer is in communication connection with the gas alarm system. Meanwhile, the present invention discloses a control method of the LNG filling station intelligent control system. The LNG filling station intelligent control system of the present invention integrates the control of the parts of an LNG filling station highly, realizes the centralized acquisition, display and control, solves the problems that a conventional LNG filling station is dispersive in control, and the devices can not work cooperatively and effectively, and operates safely.

Description

technical field [0001] The invention relates to a gas filling station control system, in particular to an intelligent control system of an LNG gas filling station and a control method thereof. Background technique [0002] At present, most of the control systems of LNG filling stations are in a decentralized control mode. The operation of various equipment cannot achieve safe and effective information exchange, and the production capacity of process equipment cannot be fully utilized. At the same time, equipment monitoring and safety monitoring cannot be coordinated and unified. Hidden dangers have been buried in safe operation. Contents of the invention [0003] The purpose of the present invention is to provide a highly integrated control system for each part of the LNG gas filling station in view of the above-mentioned problems, which achieves centralized collection, display and control, and solves the problem that the control of the current LNG gas filling station is s...
