Non-contact infrared temperature detection and RFID technology access control design

Abstract

The non-contact infrared body temperature detection and RFID technology access control design uses 51 single-chip microcomputer as the core main control module, which combines infrared temperature measurement function (GY-MLX90614 sensor) and radio frequency (MFRC522) card swipe access control system, through swiping card and temperature measurement together control the door opening and closing. When it works in the high-risk zone mode, it detects the body temperature while swiping the card. If the body temperature is normal, the door opens, if the body temperature is abnormal, the door does not open and the buzzer sounds; when working in the low-risk mode, if the body temperature is normal, the door opens, If the body temperature is abnormal, the door opens and the buzzer sounds. Finally, it inputs the obtained card information and body temperature data to the WiFi circuit (ESP8266) through the serial port, and uses it as a hotspot to connect to the mobile device to realize data transmission, so as to realize more efficient unmanned management in different areas during the epidemic.

Advanced Pedestrian State Sensing Method for Automated Patrol Vehicle Based on Multi-Sensor Fusion

“…Considering the difficulty of detecting body temperature without distance limitation, this method could measure temperature accurately by strictly fixing the temperature measurement distance and controlling environmental variables. Based on the micro control system 51 series (MCS 51) equipped with infrared temperature measurement function (GY-MLX90614 module), Zhu et al [29] designed a non-contact infrared temperature measurement system and applied it to the access control platform in the community. As the distances between pedestrians and detective equipment are fixed, the influence of distance on temperature measurement accuracy is reduced.…”
