Background technique

As people pay more and more attention to health, various human physiological parameter measurement equipment is widely used in clinical diagnosis, disease monitoring, health management and other processes. Human physiological parameter measurement equipment is usually used in conjunction with sensors. These measurement equipment measure Human physiological parameters. Here, the physiological parameters of the human body refer to any parameters that can directly or indirectly indicate the physiological information of the human body, including body temperature, blood pressure, pulse, blood sugar, heartbeat, blood flow and other information.

However, due to the randomness in the production process of the sensor, or due to the aging of the sensor, the measurement results of the sensor may have certain deviations from the actual results. Therefore, in order to obtain a sufficiently high measurement accuracy, it is often necessary to calibrate the sensor. Due to the random nature of the bias of each sensor, the calibration parameters used to calibrate the sensors are often different.

In the prior art, the calibration parameters of the sensors are stored in the measuring equipment, and the measuring equipment uses the calibration parameters to calibrate the signals measured by the matching sensors. When the sensor is replaced, the human body parameter measurement device needs to be replaced accordingly, or the calibration parameters stored in the measurement device need to be updated. This approach results in high cost and inconvenient use of anthropometric measurement equipment.

Therefore, it is necessary to improve the prior art.
