A star network method for biological signal sensors and collectors

Abstract

A star-shaped networking method for biological signal sensors and collectors, comprising the following steps: S1: start; S2: wireless networking parameter configuration; S3: start networking; S4: determine whether the networking is successful; S5: signal concentrator Re-power on the signal terminal; S6: The signal terminal in the star network transmits the collected corresponding data and communication status to the signal concentrator with the default transmission power of +20dBM. The present invention realizes simple and intuitive wireless networking, network distribution, and communication between multi-channel biological signal collectors and sensors. Each star network has its own data transmission rate, stable bandwidth frequency and other functions, from The data packet loss rate caused by data collision is avoided in physical space, and the integrity of data is greatly guaranteed in terms of time.

Description

A star networking method for biosignal sensors and collectors technical field The present invention relates to multi-channel biological signal acquisition field, relate in particular to a kind of biological signal sensor and collector Star networking method. Background technique [0002] The current multi-channel biological signal acquisition instrument is generally 4 or more acquisition input channels, directly through the cable Connect to different biosignal sensors. If the collector requires multiple sensor data, multiple cables are required to In this way, the sensor cables directly influence each other, and the placement of the sensor on the living body is also affected to a certain extent. In severe cases, it will directly lead to poor release or detachment of the sensor and the organism, which will eventually affect the collected data and cause experimental problems. fail. [0003] Now another company has introduced the wireless connection method of the biolo...

AI Technical Summary

Problems solved by technology

[0005] In the existing technology, the transmission mode between the existing multi-channel biological signal collector and the sensor is wired transmission, which is not conducive to the collection and use of multi-sensors. It is difficult to collect ideal data in some experimental scenarios through wired transmission; while wireless The transmission method has technical problems such as difficulty in implementation and unstable transmission

In the real-time acquisition of biological signals, the absence of signals is not allowed in some experiments (such as EEG, ECG, EMG)
