Abstract
This paper proposes a hospital medical gas monitoring system based on optical fiber ring network aiming to solve the problems of current medical gas monitoring, for example, the function of acquisition points is single, data transmission is not real-time, and communication distance is short. This system can display real-time gas state data and alarm in time by using the multi-function regional monitoring alarms as monitoring nodes. Meanwhile, we use multi-mode optical fiber ring network to connect the monitoring nodes throughout the hospital because of a long-distance transmission. Experimental results show that the system has the features of multifunction, safety, reliability, convenience and utility.
Highlights
Medical gas project is known as one of the life support system, whose normalization, safety, reliability and reasonability directly related to the patient’s life safety [1]
Most of the existing hospital medical gas monitoring systems use the method of installing the pressure or flow meters in the gas equipment as gas parameter acquisition node
The hospital medical gas monitoring system based on multi-mode optical fiber ring network includes several important modules to ensure achieve the desired results, such as regional monitoring alarm and regional monitoring panel
Summary
Medical gas project is known as one of the life support system, whose normalization, safety, reliability and reasonability directly related to the patient’s life safety [1]. Most of the existing hospital medical gas monitoring systems use the method of installing the pressure or flow meters in the gas equipment as gas parameter acquisition node. This gas parameter acquisition node has only a single function, so it need artificial screening. Multi-mode fiber supports longer transmission distance, it can support up to 2000 meters’ transmission distance when used in 10Mbps and 100Mbps Ethernet In this system, gas state data acquisition nodes of each regional monitoring subnet communicate with each other through fieldbus, regional monitoring subnets throughout the hospital are connected by multi-mode fiber ring network [2]
