"基于单片机的多功能跑步监测系统设计与实现"

Based on the document "Multi-functional Running Monitoring Instrument Based on Single Chip Microcomputer.doc", this design was completed in the PROTEUS environment. The hardware circuit and software system of the multi-functional real-time physiological parameter monitoring system, composed of the single-bus digital temperature sensor DS18B20, AT89C51 single-chip microcomputer, HK-2000A integrated pulse sensor, ND-3 micro vibration sensor, and LM041L character display, are described in this paper. The structure, performance characteristics, and working principle of PROTEUS and KEIL software, DS18B20 single-bus digital temperature sensor, AT89C51 single-chip microcomputer, and LM041L character display are introduced. In addition, the performance parameters of the HK-2000A integrated pulse sensor and ND-3 micro vibration sensor are also presented. The system can complete the collection, processing, and display of parameters such as temperature, heart rate, and number of steps, and can also provide alarm prompts when these parameters exceed the set threshold.
