Electromyographic signal, mechanical signal and high speed image simultaneous acquisition system and method

Abstract

The invention provides an electromyographic signal, mechanical signal and high speed image simultaneous acquisition system and method. The system comprises an electromyographic signal acquisition module, a mechanical signal acquisition module, a high-speed image acquisition module, a synchronization acquisition trigger module, a control module, a storage module and a storage module. At work, the synchronization acquisition trigger module sends a step signal to three acquisition modules at the same time to trigger the modules to work. Three acquisition modules acquire the electromyographic signal, the mechanical signal and the image of a target based on the absolute time. The control module integrates the acquired electromyographic signal, mechanical signal and image based on the absolute time to form the synchronization data of the electromyographic signal, the mechanical signal and the high-speed image, stores the data in the storage module, and controls the display module to display the synchronization data. According to the invention, electromyographic and mechanical signals produced by the movement of an animal and the movement posture are synchronously measured and stored; and the system and method are suitable for occasions in which three kinds of data are mutually associated when the animal movement is analyzed.

Description

technical field [0001] The invention relates to the synchronous measurement of posture, myoelectric signal and mechanical signal when animals are crawling, in particular to a synchronous acquisition system and method of myoelectric signal, mechanical signal and high-speed image. Background technique [0002] Biological robot refers to the use of animal body's motor function and power supply system, starting from the sensory input or innervation of animal movement, to realize the artificial control of animal movement and certain behaviors. In the development process of biological robots, the extraction and analysis of the original biological signals of animals is a necessary premise and basis. These biological signals include EEG, EMG, ECG, pulse, blood pressure, respiratory volume, etc. Accurate acquisition and analysis of signals is of great significance to the research of animal robots. The research and development of corresponding acquisition instruments, equipment or de...
