Embodiment Construction

[0023] refer to figure 1 shown. The present invention adopts an ARM11 processor as the CPU, and the functions of the CPU include realizing video data acquisition control, image processing and alarm control.

[0024] figure 2 It is a schematic diagram of the connection between the microprocessor and the video module in this embodiment. Because of the ITU656 encoding method, only 8 data lines and a pixel clock are required. The video module is controlled through the IIC bus. Because it is a high-frequency signal, it has certain requirements for the anti-interference of the circuit.

[0025] image 3 It is a schematic circuit diagram of the alarm module of this embodiment. The module is controlled by two pieces of 555. The first piece of 555 constitutes a monostable trigger circuit for controlling the alarm time; the second piece of 555 constitutes a multivibrator for controlling the frequency of the buzzer and indicator light.

Abstract

The invention relates to a system designed for the fatigue status of a person. The system comprises a video module, an alarm module, a memory and a microprocessor, wherein the video module is used for acquiring external image information and converting an analog video signal into a digital video signal; the alarm module is used for alarm reminding; the memory is used for storing the information; and the microprocessor is used for processing the video signal and controlling the alarm module connected with the microprocessor. The system is characterized by being flexible, efficient and accurate; and by adopting the system, various accidents caused by fatigue of the person can be effectively reduced.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to a fatigue monitoring system. technical background [0002] The fatigue monitoring system is used to monitor the fatigue state of the staff during the work process in real time, and give corresponding alarms according to the fatigue state of the staff to remind the staff to stop working or perform other operations. Objective methods can be through EEG, electrooculogram, electromyography, respiratory airflow, electrocardiogram, etc. Although these methods are relatively accurate, because these methods are generally measured before or after work, they are non-real-time measurements that are leading or lagging. At the same time, it is very difficult to install complex monitoring instruments in a limited space, and the mental state of the staff changes greatly before and after work and departure, and accurate measurement will be greatly affected. Therefore, it becomes necessary to...
