Abstract

The invention discloses an electroneurographic signal compression sensing processing method and an electroneurographic signal compression sensing processing circuit, which belongs to the technical field of electroneurographic signal processing. By means of compressing all the electroneurographic signals in the current data compression section containing the peak, the current data compression section refers to N electroneurographic signal data where the detected peak exists, and the electroneurographic signals of the current data compression section without the peak are removed, so that the data of the time period in which the peak is positioned are all output, the peak signals in the electroneurographic signals are relatively completely retained, the problem of the poor reconfiguration performance due to the uneven connection between peak and non-peak of electroneurographic signals. is effectively solved; in addition, by means of the device, subtraction and comparison operations needed to find the maximum difference between adjacent sampling points in the effective potential signal segment in the peak alignment phase in the traditional electroneurographic signal processing is avoided, therefore, the calculation amount of the circuit is less and the hardware resource consumption is lower.

Description

technical field [0001] The invention relates to a neural electrical signal compression sensing processing method and a circuit, and belongs to the technical field of neural electrical signal processing. Background technique [0002] The wireless body area network is a wireless network system composed of wearable or embeddable sensor nodes, central nodes, remote servers and other related devices centered on the human body. Its operation process can be described as follows: wearable or embeddable sensor nodes The bioelectric signal is collected and sent to the central node wirelessly; then, the central node processes the collected signal or sends it directly to the remote server; finally, the remote server processes and evaluates the received signal. [0003] Wearable or embeddable sensor nodes use battery power and send signals wirelessly, their energy is limited and wireless transmission consumes a lot of power.
