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)

Embodiment

[0062] Embodiment: adopt CY-1000 biological signal acquisition instrument;

[0063] The signal concentrator is inserted into the acquisition instrument; the three signal terminals of ECG, tension and body temperature and the biological signal acquisition instrument are powered on at the same time, and the network is formed according to the above-mentioned networking process to realize a one-to-three star network.

[0064] The parameters of the signal concentrator are set to network address 0x01, network frequency 430, network bandwidth 1M, communication frequency 9600bps; signal terminal network address is 0x01; the device numbers of the three terminal devices themselves are respectively counted as terminal device 101, terminal device 102 and terminal device 103.

[0065] After the networking is successful, signal collection can be carried out. At this time, the biological signal acquisition instrument will analyze and extract the data transmitted from the single signal termin...

Abstract

A star networking method for a biological signal sensor and a collector comprises the following steps: S1, starting; S2, configuring wireless networking parameters; S3, starting networking; S4, judging whether networking succeeds or not; S5, powering on a signal concentrator and a signal terminal again; and S6, enabling the signal terminal in the star network to transmit the acquired correspondingdata and communication state to the signal concentrator at default +20 dBM transmitting power. According to the invention, simple and intuitive wireless networking, network distribution and communication between the multi-channel biological signal collector and the sensor are realized, and the respective data propagation rate, stable bandwidth frequency and other functions are realized among thestar networks, so that the data packet loss rate caused by data collision is avoided in a physical space, and the integrity of the data is greatly ensured in time.

Description

technical field [0001] The invention relates to the field of multi-channel biological signal acquisition, in particular to a star-shaped networking method of biological signal sensors and collectors. Background technique [0002] The current multi-channel biological signal acquisition instrument generally has 4 or more acquisition input channels, which are directly connected to different biological signal sensors through cables. If the collector needs multiple sensor data, multiple cables are required for use, which will cause direct interaction between the sensor cables, and at the same time, the placement of the sensor on the organism will also be affected to a certain extent. In severe cases, it will directly lead to the release of the sensor from the organism Defective or shedding phenomenon will eventually affect the data collection and cause the experiment to fail. [0003] Now some companies have launched wireless connection methods between biological signal collecto...
