"基于单片机的心率监测系统设计及实现"

Design of the heart-rate monitoring system based on single-chip microcomputer is essential in various fields such as healthcare and sports. Traditional heart-rate monitoring systems often have limitations such as being located in a single location, lack of real-time accuracy, and high maintenance costs. This design aims to overcome these limitations by emphasizing affordability, simplicity of use, and low maintenance costs. The heart-rate monitoring system designed in this project utilizes an optical sensor based on the principle of optical induction to convert heart-rate signals into measurable analog electrical signals. To achieve accurate heart-rate calculations, the system is equipped with a low-cost and powerful AT89S52 single-chip microcontroller. By utilizing the interrupt and timer functions of the microcontroller, precise heart-rate measurements can be obtained. After the hardware and complete software algorithm were developed, extensive testing was conducted to ensure the effectiveness of the design. The test results demonstrated that the system met the expected performance requirements and provided accurate heart-rate monitoring capabilities. In conclusion, the design of the heart-rate monitoring system based on single-chip microcomputer offers a cost-effective and user-friendly solution for monitoring heart rates in various applications. The utilization of an optical sensor and AT89S52 microcontroller enables accurate and reliable heart-rate measurements, making it a valuable tool for healthcare professionals and fitness enthusiasts. This design represents a significant advancement in heart-rate monitoring technology, providing a practical and efficient solution for real-time heart-rate monitoring.
