Test device and test method for heart rate module

Abstract

The invention relates to a test device and a test method for a heart rate module. The test device comprises a substrate used for carrying the heart rate module, a support structure arranged on the substrate, a PCB, an upper computer in communication connection with the heart rate module via the PCB, an MCU module in communication connection with the upper computer, an optical receiver used for receiving a light intensity signal emitted by an LED in the heart rate module, and a laser transmitter used for transmitting the light intensity signal to a heart rate receiving end of the heart rate module, wherein the optical receiver and the laser transmitter are corresponding to the heart rate module and arranged on the support structure; and both the optical receiver and the laser transmitter are in communication connection with the MCU module. The device and the method are used for measuring the light intensity signals transmitted and received by the LED in the heart rate module, and detecting whether the heart rate module is normal, so that reliability and accuracy of the heart rate module in use are improved, and user experience is enhanced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a test device and a test method for a heart rate module. Background technique [0002] Whether the heart rate is normal is an important indicator to reflect the health of the human body. Always understand the changes in the heart rate of the human body, and maintain good health by adjusting living habits such as diet and exercise. The state of the human body is not static. The heart rate is different in different time periods and different physical states. Keep abreast of heart rate changes and prevent physical diseases in advance. [0003] At present, with the rise of smart wearable products, more and more sports bracelets and smart watches are on the market. Some of these smart wearable products are mainly aimed at monitoring physical health conditions, such as exercise conditions, heart rate, sleep conditions, etc. Therefore, Heart rate modules have been wid...

Problems solved by technology

The existing heart rate detection method captures the optimal value of the brightness of the LED component by taking pictures of the CCD, but the LED flickering may not be able to accurately capture the optimal value of the brightness, and due to the interference and the influence of the shooting gap, the measurement can only be performed qualitatively, so It is impossible to determine whether the heart rate return value read at the moment is within the accurate ra
