An indoor correction infrared temperature sensor device based on uwb ultra-wideband

Abstract

The invention discloses an indoor correction infrared temperature measurement sensor device based on UWB ultra-wideband, which includes a UWB positioning system for locating the coordinates of the forehead position of a monitored person; an infrared temperature sensor for monitoring the temperature of objects within the range; an information processing module, It is used to receive position coordinates and temperature data sent by each infrared temperature sensor in real time; the display module is used to receive the position information and body temperature data of all monitored people in the room from the information processing module, and display them on the map screen; UWB positioning technology is used as The auxiliary means greatly improves the accuracy of the temperature measurement method with the temperature sensor as the core. At the same time increased the positioning function.

Description

technical field [0001] The invention relates to the fields of human body temperature detection technology and the like, specifically, an indoor correction infrared temperature measurement sensor device based on UWB ultra-wideband. Background technique [0002] Common indoor wireless positioning technologies include WiFi, Bluetooth, etc., but WiFi can only achieve complex and large-scale positioning, and the accuracy is only about two meters. The stability of the Bluetooth system is poor, and noise interferes greatly with the signal. UWB ultra-wideband positioning technology is a positioning technology using ultra-wideband wireless communication. Ultra-wideband communication refers to a wireless communication technology with ultra-high bandwidth by sending and receiving extremely narrow pulse transmission data at or below the nanosecond level. When performing three-dimensional space positioning, UWB has the characteristics of simple structure, strong stability, high precision...

AI Technical Summary

Problems solved by technology

At present, the widely used products mainly include forehead thermometers and fixed infrared thermometers placed at gates, but both have certain defects. The former can only measure a single target at a time, which is inefficient and not suitable for scattered passenger flow. The latter analyzes the thermal imaging parameters of the shooting crowd. It is difficult to achieve accurate detection when multiple targets are too close to each other and cannot guarantee a high standard of simultaneous measurement of the number of people.

[0006] When preparing to resume work after the epidemic, for returning employees, real-time monitoring of indoor personnel body temperature is another problem that needs to be solved. The above two methods cannot take into account the requirements of economy, accuracy and efficiency.
