Description

Electrolysis oxygen supply system based on medical oxygen channel pressure data Technical Field The invention relates to the technical field of medical oxygen supply control, in particular to an electrolytic oxygen supply system based on medical oxygen channel pressure data. Background In a medical oxygen supply scene, the prior art mainly aims to solve the problems that when the actual oxygen consumption of a hospital changes, an electrolytic oxygen generating device can timely adjust the oxygen supply to avoid insufficient oxygen supply or excessive oxygen supply, and the common practice is to collect pressure data on a medical oxygen channel and then control an electrolytic tank to increase the oxygen yield, reduce the oxygen yield or execute start-stop control according to the pressure, the pressure drop speed or the pressure change condition in a period of time; However, in the real application of centralized oxygen supply in hospitals, the medical oxygen channel is not an empty channel for simply transmitting oxygen, a certain amount of oxygen is originally stored in the channel, and when a plurality of ward terminals are started to absorb oxygen in a short time, the oxygen absorption flow rate is adjusted to be high or the oxygen is concentrated in a staged way, the existing oxygen in the channel is released to participate in oxygen supply, so that the pressure is reduced in the stage of the initial change of the oxygen consumption, but the reduction does not necessarily mean that a gap which can be filled by the oxygen supply is newly added by the electrolysis equipment immediately; that is, the prior art sees the result of pressure drop, but behind the result, the original oxygen in the channel is only changed in a short time due to normal release, the actual oxygen supply deficiency which cannot be recovered by the channel itself is developed, because the prior art usually directly takes the result of pressure change to drive the electrolysis oxygen generation regulation, the prior art does not continuously judge which part of the pressure drop can be digested by the release and the stabilization of the channel itself, which part is beyond the bearable range of the channel itself, two kinds of conditions which can be directly observed easily occur in actual operation, one kind is that the device acts too early and frequently, the oxygen yield is just supplemented, the pressure is quickly risen, even reverse fluctuation occurs, the other kind is that the actual oxygen supply gap is formed, but the system still processes according to the general pressure fluctuation, so as to lead to compensation lag, so the key of the problem is not to whether the pressure data is adopted, or not to make the regulation, but the prior art cannot accurately separate which part of the oxygen in the current pressure drop is released by the normal change only according to the original pressure change of the medical oxygen channel, which part already belongs to the true gap which must be compensated by the new oxygen addition of the electrolysis device; therefore, the technical problem to be solved by the application is how to accurately distinguish the part which can be recovered by the medical oxygen channel in the pressure drop from the part which must be compensated by the newly added oxygen supply of the electrolysis when the electrolysis oxygen supply is regulated based on the pressure data of the medical oxygen channel.
