Wireless distributed synchronous electrocardiogram real-time monitoring system

Abstract

The invention provides a wireless distributed synchronous electrocardiogram real-time monitoring system which comprises a plurality of terminal sensor nodes, a coordinator and an upper computer, and is characterized in that the terminal sensor nodes are distributed on the body surface of a human body to collect electrocardiogram signals at different positions and send data to the coordinator in a time-sharing manner; the coordinator establishes a single-hop wireless sensor network with the terminal sensor nodes to realize synchronous acquisition triggering and synchronous accumulative error suppression of all the terminal sensor nodes, and transmits acquired data to the upper computer; the upper computer carries out processing such as difference and filtering on data of every two terminal sensor nodes to obtain multi-lead electrocardiosignals, and the multi-lead electrocardiosignals are displayed and stored in real time. The wireless sensor network synchronization technology is applied to multi-lead electrocardiogram real-time monitoring, sensor distributed synchronous electrocardiogram real-time monitoring is achieved, the constraint of lead wires in a traditional wired mode is eliminated, and the sensor nodes of the system have the remarkable advantages of being extensible, wearable, miniaturized and the like.

Description

technical field [0001] The invention relates to an electrocardiogram monitoring system, in particular to a distributed synchronous electrocardiogram real-time monitoring system based on a wireless sensor network. Background technique [0002] Heart disease is one of the most important diseases that threaten human life and health in today's society. For patients with heart disease, real-time monitoring of heart health can effectively reduce the incidence rate, and electrocardiogram detection is one of the reliable detection methods commonly used in the diagnosis of cardiovascular diseases. In modern medicine, conventional 12-lead ECG monitoring can already obtain accurate ECG data clinically, but conventional ECG detection has high requirements for patient position and relatively complicated skin treatment steps, and the Long lead wires are required to connect the ten electrodes to the test equipment, and the equipment is cumbersome and difficult to carry. Wearable ECG moni...

Problems solved by technology

At present, several commonly used wireless transmission methods include wifi wireless technology, Bluetooth wireless technology, and zigbee wireless technology. Wifi wireless technology is suitable for short-distance transmission, but the power consumption is high; Bluetooth technology has a short communication distance and cannot perform multi-point transmission. ;The biggest advantage of zigbee is that it is convenient to form a network. It can realize the management of multiple network nodes, and the network scale is large. However, it is mostly used in the management of industrial non-real-time system nodes, and it is not involved in the management of real-time system nodes.

Most of the wireless communication technologies currently used in ECG monitoring are only responsible for the data communication between the device and the host computer, and do not solve the problem of the physical lead wires of the electrodes in the case of multiple leads. For this reason, a distributed ECG measurement system is needed. system and method
