Portable Bioelectrical Signal Acquisition System with Waterproof Performance

Abstract

The invention relates to the field of bioelectric signal acquisition, in particular to a portable bioelectric signal acquisition system which can work underwater and has waterproof performance. The system mainly comprises four parts including hardware, software, a fixing device and a background system; the hardware comprises a signal acquisition module, an independent storage module, a power management module, a wireless communication module and the like; the hardware part is subjected to watertight treatment and is installed in a waterproof, corrosion-resistant, pressure-resistant and high-temperature-resistant equipment cabin; the equipment cabin is arranged on the fixing device, and the fixing device is fixed to an organism through vacuum adsorption or corset wearing. The software comprises a collection system, background system signal processing software, mobile phone APP control software, independent data storage control software and the like. The movement state and environmentalinformation of the organisms are collected while biological electric signals such as multi-channel myoelectric signals and brain electrical signals are collected through the collection system; all thesignals and power sources are wirelessly transmitted, and by controlling the sampling speed through instructions and using independent storage, the power consumption can be reduced, and large-capacity storage can be realized.

Description

technical field [0001] The invention relates to a bioelectric signal collection system, especially a portable bioelectric signal collection system with waterproof performance, which can realize wireless transmission and storage of collected data, wireless control and wireless charging of the system. Background technique [0002] All kinds of organisms have the performance of electrical activity, ranging from whales to bacteria, all have strong or weak bioelectricity. Bioelectricity is a reflection of normal physiological activities. Under certain conditions, bioelectricity is regular in a statistical sense, and certain physiological processes correspond to certain electrical responses. The physiological state of organisms can be inferred from changes in bioelectricity. At present, the main bioelectrical activities studied include EEG, ECG and EMG. Since the bioelectrical signal is relatively weak, the EEG is at the uV level and the myoelectricity is at the mV level, so it i...
