Oxygenerator centralized control method and device

Abstract

The invention embodiment provides an oxygenerator centralized control method and a device, and belongs to the technical field of medical oxygenerator automatic control. According to the method and thedevice, when starting instruments are generated, a plurality of oxygenerators at closing states are taken as oxygenerator candidates, the accumulation operation time of each oxygenerator candidate isobtained, and at last, the oxygenerator candidate with the shortest accumulation operation time period is controlled to start working; in each time, the oxygenerator candidate with the shortest accumulation operation time period turned preferably in needed on starting of an oxygenerator, so that it is avoided that only one oxygenerator is at working states for a long term, balancing of the accumulation operation time of the oxygenerators is realized, and the different of the accumulation operation time of the oxygenerators are controlled from being too big.

Description

technical field [0001] The invention relates to the technical field of automatic control of medical oxygen generators, in particular to a centralized control method and device for oxygen generators. Background technique [0002] At present, most of the oxygen generators used in the domestic industrial and medical fields are more than 3 per project. The working mode is to connect the gas storage tank in parallel at the output end, and each oxygen generator starts and stops switching according to the set oxygen outlet pressure range. In order to save energy while taking into account the service life of the oxygen generator, generally set different start pressure and stop pressure for each machine. [0003] The disadvantages of this decentralized control are as follows: the final total running time of several machines is very different, and there is always a machine whose running time is far longer than other machines, while some machines are hardly running; after-sales mainte...

Problems solved by technology

[0003] The disadvantages of this decentralized control are as follows: the final total running time of several machines is very different, and there is always a machine whose running time is far longer than other machines, while some machines are hardly running; after-sales maintenance is inconvenient. The time and the number of starts and stops are different, and maintenance needs to be divided into multiple times, and only one machine can be maintained at a time; the machine runs independently on the spot, and management personnel and after-sales personnel cannot monitor it in real time. It cannot be automatically cut off from the system when the concentration is low, the oxygen pressure is low, etc.
