Centralized oxygen supply system and control method

Abstract

The invention discloses a centralized oxygen supply system which comprises a first gas supply branch circuit, a second gas supply branch circuit, a gas supply main circuit, a PLC (Programmable Logic Controller) and an alarm, wherein gas supply pipes of the first gas supply branch circuit and the second gas supply branch circuit are combined and then the combined branch circuit is connected with the gas supply main circuit; a gas output pipe of the gas supply main circuit is fed to an oxygen house; and the PLC is used for controlling the switching on / switching off of each gas circuit according to the pressure of each gas circuit. The invention also discloses a control method for the centralized oxygen supply system; the PLC main controller is used for detecting the pressure of the first gas supply branch circuit; if the pressure is normal, gas is supplied by the first gas supply branch circuit, and otherwise, an alarm signal is sent and the pressure of the first gas supply branch circuit is detected; if the pressure is normal, the gas is supplied by the first gas supply branch circuit; and the processes are repeatedly circulated. The centralized oxygen supply system for centrally supplying oxygen, which is disclosed by the invention, has the advantages that main and standby are circularly used, so that the oxygen can be continuously and stably supplied; a central controller is automatically switched, and thus simpleness in operation and high efficiency are obtained; due to the adoption of sound and light alarm, accidents are avoided; low-pressure gas supply ensures the safety and the reliability; the centralized oxygen supply system is quick and convenient in use; and the equipment is centralized, so that less space is occupied.

Description

technical field [0001] The invention relates to an oxygen supply system, in particular to an automatically controlled centralized oxygen supply system and a control method. Background technique [0002] In places with large oxygen consumption, such as hospitals, oxygen bars, etc., there are often multiple rooms that need continuous oxygen supply. Currently, the simple oxygen cylinders or oxygen generators used for oxygen supply are inconvenient to use, waste manpower, have many and scattered equipment, and are inconvenient to manage. shortcoming. Therefore, the oxygen supply of traditional oxygen cylinders or oxygen generators has become less and less suitable for the centralized management needs of modern society. Contents of the invention [0003] The object of the present invention is to provide an automatically controlled centralized oxygen supply system and a control method in order to solve the above problems. [0004] In order to achieve the above object, the pres...
