A non-contact intelligent temperature acquisition and monitoring system based on FPGA

Abstract

Nowadays, the global epidemic prevention and control has entered a normalization, but the temperature detection task in traditional epidemic detection is heavy, and the detection speed of common equipment in the market is slow and the supervision is inconvenient. In order to reduce the work intensity of human body temperature detection, reduce the probability of virus infection, and improve the screening and interrogation efficiency of abnormal people, a non-contact intelligent temperature acquisition and monitoring system based on FPGA is designed. In this system, FPGA is used as the main control unit of the temperature measurement system, and the infrared temperature sensor MLX90614 based on the principle of infrared radiation is used for non-contact temperature measurement to collect temperature data, and then the corresponding temperature data is displayed on the OLED display. At the same time, the ESP8266 WIFI module is used to synchronize the temperature data to the host computer to realize remote temperature monitoring. When the temperature exceeds a certain value, the host computer sends out an alarm of excessive temperature. The system has good practicability, suitable for hospitals, schools, shopping malls and other crowded areas, convenient management. It can also be used for real-time inspection of temperature changes of products and materials in the factory, research and development of production areas.
