Abstract
ObjectiveTo design a set of safety power supply for hospital central oxygen supply monitoring system.MethodsThrough the safety circuit design, circuits such as over-current protection, overvoltage protection, optical coupling isolation feedback control circuit, remote monitoring interface were designed, which guarantee protection functions of accurate current limiting protection, over voltage, overload and remote monitoring.Results The safe power supply can work stably for a long continuous time, and the output ripple is less than 1%. The over-current protection and overload protection circuits can work properly to guarantee the safety of the power supply.ConclusionThe safe power supply can offer power to the hospital central oxygen supply monitoring system properly, and can work stably in the condition of oxygen leakage. Even if malfunction happens, it will not cause ifre. This design can signiifcantly improve the machine safety coefifcient and the practical value of the hospital center oxygen supply monitoring system, helping to improve intelligent management level of hospital central oxygen supply monitoring system.关键词
