Abstract:
1. A non-contact temperature-measuring device, comprising: a distance sensor unit for measuring a target's distance; an alarm unit for giving an alarm when the target's distance falls into a predetermined absolute value range; a temperature sensor unit for measuring the target's temperature after the alarm unit gives the alarm; a microprocessor unit for storing the temperature value measured by the temperature sensor unit, for processing a distance signal indicating the target's distance measured by the distance sensor unit and a temperature signal indicating the target's temperature measured by the temperature sensor unit, and for sending a command for the alarm unit to give an alarm when the target's distance value measured by the distance sensor unit falls into the predetermined absolute value range; and a display unit for displaying the target's temperature value measured by the temperature sensor unit and processed by the microprocessor unit subsequently; wherein the target's distance is obtained by the difference in radiant energy between the time when the distance sensor unit emits a radiation and the time when the distance sensor unit receives the reflected radiation after hitting the target; and wherein the distance sensor unit is configured for performing the following steps:
