Abstract

The invention discloses a DSP-based heart rate measurement device. The DSP-based heart rate measurement device comprises a DSP controller, a heart rate sensor, a signal amplification and shaping circuit, a wave trap, a storage, a displayer and a communication interface, wherein the output end of the heart rate sensor is connected with the input end of the signal amplification and shaping circuit; the output end of the signal amplification and shaping circuit is connected with the input end of the wave trap; the output end of the wave trap is connected with the input end of the DSP controller; the output end of the DSP controller is connected with the displayer and the communication interface; the storage and the DSP controller are connected. The DSP-based heart rate measurement device can accurately measure the heartbeat frequency and draw a heart sound spectrum, and can also upload power down storage and measurement data to a user mobile phone or an upper computer and give an alarm out of scope.

Description

technical field [0001] The invention relates to a device for measuring heart rate, in particular to a device for measuring heart rate based on DSP. Background technique [0002] Health is very important to everyone. There are several commonly used indicators to reflect a person's health status, such as body temperature, pulse, heart rate, and blood pressure. Heart rate refers to the number of times the human heart beats per minute. It is an important parameter to reflect whether the heart is working normally. At the same time, the heart rate value is also an important indicator to measure the intensity of physical labor and mental labor. In recent years, the incidence of cardiovascular system diseases related to the heart has been increasing year by year, especially for the elderly. The prevention and diagnosis of heart system diseases has become one of the important issues facing the medical field, and the real-time measurement of heart rate will be the key to diagnosis an...
