When specific needs, also can judge by the alarm threshold value of setting, surpass threshold value and then send sound, light warning by the hummer and the alarm lamp that are contained on the infrared forehead table of locate mode noncontact temperature rapid detection apparatus inside or the shell.
For this reason, can set the high temperature and the low-temperature warning threshold value of the infrared temperature check instrument of locate mode noncontact earlier by keyboard and display before.
The locating device location process can have multiple, and present embodiment is in conjunction with this extraordinary circumstances of forehead temperature survey, and utilize following method location: display lamp is lighted, and makes the measured see the surperficial fixedly what comes into a driver's figure of inner casing clearly and gets final product.
Guarantee the optimum measurement effect, also need carry out following steps: the fixed position of infrared measurement of temperature assembly aligns the infrared measurement of temperature assembly temperature-sensitive zone and the gaging hole collimation of casing front surface; Transparent measurement and positioning window is positioned at the gaging hole below of casing front surface, and the distance of transparent measurement and positioning window and gaging hole equals the mean distance of people's forehead apart from eyes; The fixing what comes into a driver's figure of and the inside surface that occupy sustained height relative with transparent measurement and positioning window in the casing, the casing inner plane is display lamp fixedly.
The invention has the advantages that: 1. the infrared body temperature rapid detection apparatus of the locate mode noncontact that is provided, do not contact human body, apart from measuring the forehead temperature fast about head part 100mm, the reaction time was less than 1 second.2. the infrared temperature check instrument of locate mode noncontact provided by the present invention can and be measured environment according to different mensuration positions, sets different alarm temperatures, and when hummer was rung, expression the measured had a fever.
Utilize the infrared temperature monitor of locate mode noncontact provided by the present invention, to the result that certain school 800 teachers and students detects, find 15 example warnings, wherein 3 people are confirmed as the patient that has a fever, fever patient recall rate 100%, and false drop rate only is 1.5%.
