Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right" and...

Abstract

The invention discloses a human body surface electromyography signal based driving fatigue detection system. The system comprises a detection module and an early warning implementation module. The detection module comprises a power supply unit, an electrode unit, a band-pass filter amplification circuit unit and a Bluetooth signal transmission unit and mainly completes human body surface electromyography signal acquisition and transmission. The early warning implementation module comprises a Bluetooth signal receiving unit, a signal processing unit, a voice alarm unit and a motor vibration unit and mainly completes human body surface electromyography signal processing and early warning implementation. The system is reasonable in structural design, cost saving is realized, human muscle surface electromyography signals are acquired in a multi-select mode, a muscle fatigue state can be recognized accurately, and a great promotion effect on utilization of surface electromyography signals for fatigue driving early warning is achieved.

Description

technical field [0001] The invention relates to the field of safe driving, in particular to a driving fatigue detection system based on human body surface electromyographic signals. Background technique [0002] In recent years, the global car ownership has continued to increase. Especially in my country, due to the improvement of people's economic conditions and the decline of car prices, cars have almost become a must-have for every family. While cars bring us the convenience of travel, they also bring a lot of safety hazards, especially fatigue driving. Although the country expressly prohibits fatigue driving through laws and regulations, there are still many drivers who continue to drive for a long time, resulting in disorders of physiological and psychological functions, and then traffic accidents occur. Moreover, fatigue driving often occurs on expressways, which can easily lead to vicious traffic accidents. This is mainly due to two aspects: first, because the driv...
