Abstract
The invention discloses an infrared temperature monitoring system for a miniature cabinet. The infrared temperature monitoring system comprises an infrared temperature sensor, a multi-way selector switch, a thermocouple digital converter, a single-chip microcomputer, an LCD, a wireless communication interface and an alarm circuit. The signal output end of the infrared temperature sensor is connected with the temperature signal input end of the multi-way selector switch. The temperature signal output end of the multi-way selector switch is in communication with the temperature signal input end of the single-chip microcomputer. The change-over signal end of the single-chip microcomputer is in communication with the change-over signal end of the thermocouple digital converter. The LCD, the wireless communication interface and the alarm circuit are respectively in communication with the single-chip microcomputer. The technology of infrared temperature measurement is adopted, and non-contact temperature measurement and acquisition are achieved; in addition, the switch cabinet is used as a unit, signal transmission is performed in a wireless mode at a short distance, and therefore the infrared temperature monitoring system is simple in structure, small in size, low in power consumption and capable of achieving online temperature monitoring.
