Remote medical data management system and wireless network communication method thereof

Abstract

The invention discloses a remote medical data management system and a wireless network communication method thereof. The system comprises a plurality of wireless nodes and an upper computer, wherein the wireless nodes conduct communication through a wireless network. The remote medical data management system and the wireless network communication method of the remote medical data management system have the advantages that a host computer can conduct remote dynamic monitoring and data management on a plurality of monitored instruments at the same time, and data resource sharing is achieved; the upper computer conducts authentication on the wireless nodes and limits use of copied nodes, so that safety is also greatly improved; the system can detect the working state and the number of the wireless nodes in the network in real time and automatically react to the emergency situations in the communication process in time so as to effectively increase the network throughput, and once the communication environment returns to normal, the communication is ensured and can further be automatically recovered orderly in time; the upper computer can dynamically adjust the communication cycle and strategy of the nodes and the upper computer, have flexible adaptability and manage the wireless nodes with the variable working states well. The wireless network communication method is easy to implement.

Description

technical field [0001] The invention relates to a remote medical data management system and a wireless network communication method thereof, belonging to the technical field of wireless communication. Background technique [0002] With the development of computer network technology, various monitoring and communication systems for computer remote control and monitoring of wireless nodes are emerging, but generally the host computer measures and monitors a fixed number of wireless nodes, and the data collection cycle is fixed. If some wireless nodes in the wireless nodes When a node fails or does not work temporarily, the communication system often takes up part of the communication time due to these inactive wireless nodes, resulting in a decrease in network communication efficiency; when a new wireless node needs to be added to the network, the host computer needs to be reset. Only by setting the relevant information of the newly added wireless nodes, and adjusting the comm...

[0002] With the development of computer network technology, various monitoring and communication systems for computer remote control and monitoring of wireless nodes are emerging, but generally the host computer measures and monitors a fixed number of wireless nodes, and the data collection cycle is fixed. If some wireless nodes in the wireless nodes When a node fails or does not work temporarily, the communication system often takes up part of the communication time due to these inactive wireless nodes, resulting in a decrease in network communication efficiency; when a new wireless node needs to be added to the network, the host computer needs to be reset. Only by setting the relevant information of the newly added wireless nodes, and adjusting the communication protocol and timing of the network, can the newly added nodes work normally, which affects the work efficiency; The node may still be collecting the data of the monitored instrument while waiting to communicate with the upper computer. For the communication protocol with the initial handshake signal, even if the upper computer is powered on again or the network returns to normal, if the hardware reset of the wireless node system is not performed, it cannot continue to work normally. communication
