Abstract
As a kind of protective equipment, helmet plays a protective role in fire emergency, rescue and disaster relief, riding and other related fields, and effectively reduces the head injury caused by accidents. However, the traditional helmet has disadvantages such as single function and complex structure. In order to solve the above shortcomings, the development of smart helmets is imperative.The intelligent helmet monitoring system designed in this paper adopts STM32 single chip microcomputer as the main control chip, and monitors the relevant parameters of the helmet through the photoresistor detection module, infrared temperature monitoring module, heart rate detection module, GPS positioning module, vibration module, ultrasonic detection module, etc. And the monitoring of light intensity, body temperature, heart rate, latitude and longitude, collision, whether there is a car and other information displayed on the LCD screen. The work of the system is as follows: 1. Hardware design, through the selection of sensor module, display module, key adjustment module to complete the hardware design. 2. Software design: C language is used as the programming language for this design, which enables the hardware to collect data, then process the data, and finally display the data and remind them. Finally, the detected data is displayed on the LCD screen, and the administrator can observe the changes of the temperature, heart rate, longitude and latitude and other related parameters of the tested person in real time through the display screen. The detection results are processed in time, and the operation and detection of the device is relatively simple, and users can also carry out self-detection. Therefore, this design can well reduce the head injury rate, and has certain research value and practical significance.
