Intelligent medical oxygen equipment monitoring system based on MQTT protocol

Abstract

The invention discloses an intelligent medical oxygen equipment monitoring system based on an MQTT protocol. The system comprises an oxygen equipment control node used for controlling on-off of oxygenequipment, switching an oxygen bottle, monitoring real-time oxygen flow data and sending an MQTT data packet containing oxygen equipment flow, oxygen equipment pressure information and an IPv6 address of the oxygen equipment control node; a MQTT proxy server used for connecting each oxygen equipment control node and storing the content of the MQTT data packet sent by each oxygen equipment controlnode; a database system used for receiving and storing the oxygen equipment information and the IPv6 address of the oxygen equipment control node; and a client which acquires state information of alloxygen equipment by accessing the MQTT proxy server and the database system. The system has the beneficial effects that the network load is effectively reduced, the client realizes a comprehensive log function and an alarm function, the safety index of a patient is greatly increased, doctor-patient disputes are reduced, the medical cost is saved, and the modernization level of gas management is improved.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to an MQTT protocol-based intelligent medical oxygen equipment monitoring system. Background technique [0002] In recent years, with the increasing modernization of hospitals, medical gases are used as single or mixed component gases for patient treatment, diagnosis, prevention, or driving surgical tools. Medical oxygen detection and control systems have become an integral part of hospitals. . However, the monitoring system for medical gas in the existing medical institutions is still in the non-intelligent stage, and the collection of relevant data still requires manual and regular observation, which is not only time-consuming and laborious, but also once a problem occurs, it cannot be found and solved in time. There are greater security risks. [0003] In the field of Internet of Things, due to unstable links, high packet loss rate, and high network delay, most applications d...

Problems solved by technology

The transmission distance of WiFi can reach 100 meters, but the power consumption of WiFi is large, the heat is serious and the operation is unstable for a long time

ZigBee is the most popular low-cost, low-power wireless Mesh network standard today, but the bridging between ZigBee networks and non-ZigBee networks requires a very complex application layer gateway

[0005] In the medical oxygen equipment monitoring system, a detailed log function is required to record the time, operation type, user name and IP address of each operation of the owner. In the existing IPv4 network, the IP address of each client is an intranet address , due to the variability of the intranet address, it is meaningless to record the intranet address. In the event of an accidental dispute, it is difficult to find the person who made the wrong operation

And due to the limited IPv4 address, the number of devices in the network is greatly limited
