Heart rate measuring instrument

Abstract

The invention provides a heart rate measuring instrument comprising a heart rate acquisition circuit, a heart rate amplification circuit, a heart rate comparison circuit, a main control circuit and anacquisition control circuit. The heart rate acquisition circuit includes an infrared transmitting tube and an infrared receiving tube; the heart rate amplification circuit includes a signal amplifier; the heart rate comparison circuit includes a signal comparator; the main control circuit includes a main control chip; the acquisition control circuit includes a pyroelectric infrared sensor. Through the design of an acquisition control module, the acquisition of whether or not to trigger the heart rate is automatically carried out by using the pyroelectric infrared sensor, and the trigger control of the heart rate acquisition is not required, which facilitates the operation of a user and improves the user experience; through the design of the heart rate acquisition circuit, the heart rate amplification circuit and the heart rate comparison circuit, acquisition, amplification and comparison of the heart rate can be effectively and automatically carried out, the stability of the whole circuit structure is effectively improved, and the accuracy of heat rate measuring is improved.

Description

technical field [0001] The invention relates to the technical field of heart rate detection, in particular to a heart rate detection device. Background technique [0002] With the rapid development of the economy, people's requirements for the quality of life are also rapidly increasing, and the health problems are getting more and more attention from the society, and there is a great relationship between physical examination and physical health, which is to understand the physical health status the most direct means. As one of the important indicators reflecting the health status of the human body, the detection of heart rate is particularly important. Therefore, heart rate detection equipment has become an indispensable daily necessities in family life. [0003] During the use of the existing heart rate detection device, the user needs to actively trigger the control to collect the user's heart rate, which leads to cumbersome operations for the user and reduces the user e...
