specific Embodiment 1

[0033]The invention provides a portable myoelectric detection device based on a microkernel, the device at least includes an electrical stimulation circuit, a sEMG signal detection circuit, a microprocessor, a power supply, a communication unit, and a display, and the device adopts an L4 microkernel, like figure 2 shown;

[0034] like image 3 As shown, the L4 microkernel is at least connected with the pager adjustment component running in the user state and the myoelectric data processing component running in the user state; the pager adjustment component includes the following modules:

[0035] The monitoring module is used to monitor all non-kernel state threads and their corresponding pager numbers, pager creation time, and the number of times each pager is accessed by the kernel within a certain period of time; and the pager is divided into two groups, the first group being myoelectric The pager corresponding to the thread of the data processing component, and the seco...

specific Embodiment 2

[0052] The present invention also provides a microkernel-based portable electromyography monitoring system, the system includes a server and the device according to the first embodiment, and the device establishes a connection with a mobile terminal or a server through a communication unit.

specific Embodiment 3

[0054] The present invention also provides a computer-readable storage medium on which computer program instructions are stored, and the computer program includes the following modules:

[0055] The monitoring module is used to monitor the number of pagers corresponding to all non-kernel state threads, the pager creation time, and the number of times each pager is accessed by the kernel within a certain period of time; divide the pagers into two groups, the first group is EMG data processing The pager corresponding to the thread of the component, the second group is the pager corresponding to other threads;

[0056] The adjustment module is used to judge whether the number of threads of the EMG data processing component is greater than the first preset value, if so, sort the second group of pagers according to the pager creation time and the number of times each pager is accessed by the kernel within a certain period of time , destroy part of the pagers in the second group, an...

Abstract

The invention provides portable myoelectricity detection equipment and system based on a microkernel. The stability of the portable myoelectricity detection equipment is improved by using the microkernel. Meanwhile, the microkernel is improved, when the number of threads of a myoelectricity data processing assembly is larger than a first preset value, according to the creation time of pads and the number of times that each pager is accessed by the kernel within a certain time, the pagers corresponding to the threads of a non-myoelectricity data processing assembly running in a user state are sorted, part of pagers are destroyed, and due to the fact that the pagers are also the threads, the performance of the portable myoelectricity detection equipment is improved by optimizing the pagers. The portable myoelectricity detection equipment and system based on the microkernel have the advantages that not only can the effect of guaranteeing the stable running of the portable myoelectricity detection equipment be achieved, but also myoelectricity signal data can be quickly processed.

Description

technical field [0001] The present application relates to the field of myoelectric detection, and in particular to a microkernel-based portable myoelectric detection device and system. Background technique [0002] Bioelectrical signals are weak electrical signals generated by biological organisms, such as electroencephalogram and electrocardiogram, which are the graphics displayed after the electrical signals generated by the brain and heart are amplified and filtered. With the help of these images, the health of the brain and heart can be understood Happening. Myoelectricity, as the name suggests, is the electrical signal generated by muscle tissue. Electromyography can be measured through electrodes attached to the body surface. Surface electromyography is a commonly used device in electromyography detection. Electromyography can be obtained by using an electromyography. The surface electromyography data is extremely weak, generally only 1μV-500μV. It is precisely becaus...
