Flexible dot-matrix electromyographic signal wireless acquisition system capable of realizing channel hot plugging

Abstract

The invention discloses a flexible dot-matrix electromyographic signal wireless acquisition system capable of realizing channel hot plugging. The flexible dot-matrix electromyographic signal wirelessacquisition system comprises a plurality of flexible wireless data acquisition modules and a main control unit. The plurality of flexible wireless data acquisition modules can be completely attached to all positions of a human body, and acquire and send human body electromyographic signals; and the main control unit is connected with an upper computer, and is used for receiving the human body electromyographic signals sent by the flexible wireless data acquisition modules, synthesizing an electromyographic image and sending the electromyographic image to the upper computer. According to the flexible dot-matrix electromyographic signal wireless acquisition system, plugging of an acquisition channel can be realized in an electrified state, so that the reliability, rapid maintainability, redundancy, timely recovery capability on faults, and the like of the system are improved, and the adaptability and convenience of the acquisition system are improved; meanwhile, the flexible wireless data acquisition modules can be freely increased and decreased, so that the expansibility of the acquisition system and the comfort in the wearing process are improved; and on the premise of guaranteeingthe acquisition quality, targeting and controllability of electromyographic signal data acquisition are improved, and the flexibility and convenience of the acquisition system are improved.

Description

technical field [0001] The invention relates to the technical field of wearable devices based on electromyographic signals, in particular to a flexible dot-matrix wireless acquisition system for electromyographic signals with channels hot-swappable. Background technique [0002] With the increasing development of science and technology, portable myoelectric signal acquisition equipment and posture perception equipment are widely used in rehabilitation medicine. The patient wears the device for action training, and the computer judges the patient's action intention through the collected information for human-computer interaction to improve the effect of rehabilitation training. Most of the current EMG signal acquisition devices are wireless loop or wired array. The wireless ring type has the problem of low acquisition frequency and the inability to collect signals for muscles in different positions. The wired array type has the problem of single acquisition mode and the inab...
