For achieving the above object, the present invention proposes the infrared temperature check instrument of a kind of scan-type noncontact, comprise the infrared measurement of temperature assembly, it is characterized in that: also comprise tilting member and control circuit, include drive signal generation device and temperature conversion device in the control circuit, link to each other with the infrared measurement of temperature assembly with described tilting member respectively; Described tilting member comprises motor and coupled direct supply and pendulous device; Motor is fixedly connected on enclosure, and motor shaft is connected with pendulous device, and the infrared measurement of temperature assembly is fixedlyed connected with pendulous device.
For achieving the above object, the present invention also proposes the infrared temperature check method of a kind of scan-type noncontact, it is characterized in that comprising the steps: the infrared temperature check instrument of scan-type noncontact is placed setting height; When the measured walks out-of-dately successively below the infrared temperature check instrument of scan-type noncontact, the motor-driven tilting member makes the infrared temperature check instrument of scan-type noncontact carry out infrared scan to lower zone simultaneously and surveys; After the infrared temperature check instrument of scan-type noncontact scans measured's forehead surface temperature, the forehead surface temperature is scaled body temperature through instrument internal.
Because adopted above scheme, the present invention utilizes the infrared measurement of temperature assembly to carry out thermometric, avoid contacting with human body and measuring speed fast; Simultaneously, because the mode of ingenious utilization scanning makes it need not adjust height and just can obtain the people's of different heights forehead temperature, thereby be suitable for the quick take temperature of a large amount of crowds, and the person that therefrom scans the abnormal body temperature.
Embodiment:
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
The infrared temperature check instrument of scan-type noncontact that the present invention proposes comprises infrared measurement of temperature assembly, tilting member and control circuit, include drive signal generation device and temperature conversion device in the control circuit, link to each other with the infrared measurement of temperature assembly with described tilting member respectively.
In following each embodiment:
Described tilting member comprises motor 1 and coupled direct supply and pendulous device 3; Motor 1 is fixedly connected on shell 4 inside, and motor shaft 2 is connected with pendulous device 3, and infrared measurement of temperature assembly 5 is fixedlyed connected with pendulous device 3.Referring to Fig. 1
The infrared temperature check instrument of described scan-type noncontact also comprises hummer 6, alarm lamp 7, keyboard and display, described hummer 6 all links to each other with control device with alarm lamp 7, be fixed on shell 4 outside surfaces (still seeing Fig. 1), be used for when temperature surpasses preset threshold, reporting to the police; Keyboard also links to each other with control device with display, is used to be provided with alarm threshold value.
The infrared temperature monitor Circuits System of scan-type noncontact connection diagram is seen Fig. 2.
Fig. 3 has represented the infrared temperature monitor pendulous device of scan-type noncontact embodiment one.Pendulous device described in this example 3 is forks 11, and it and motor shaft 2 are rigidly connected, and swing with motor positive and inverse; Be provided with the limit switch 13 and the driving lever 12 that are used for motor commutation, limit switch 13 occupy driving lever 12 both sides, and infrared measurement of temperature assembly 5 is rigidly connected with fork 11.
Fig. 4 has represented the infrared temperature monitor pendulous device of scan-type noncontact embodiment two.In this example, described pendulous device 3 is crank 15, connecting rod 14 and fork 16, and motor shaft 2 is fixedlyed connected with crank 15, and crank 15 props up with the movable strand of an end of connecting rod 14, the other end of connecting rod 14 and rocking bar 16 movable strands are propped up, and rocking bar 16 is fixedlyed connected with infrared measurement of temperature assembly 5.
Fig. 5 has represented the infrared temperature monitor pendulous device of scan-type noncontact embodiment three, in this example, described pendulous device 3 is crank 17 and rocking bar 18, motor shaft 2 is fixedlyed connected with crank 17, crank 17 flexibly connects with the chute of rocking bar 18, the movable strand of one end of rocking bar 18 and shell is propped up, and rocking bar 16 is fixedlyed connected with infrared measurement of temperature assembly 5.
Utilizing above-mentioned instrument to carry out the infrared temperature check method of scan-type noncontact comprises the steps:
The infrared temperature check instrument of scan-type noncontact is placed setting height;
When the measured walks out-of-dately successively below the infrared temperature check instrument of scan-type noncontact, the motor-driven tilting member makes the infrared temperature check instrument of scan-type noncontact carry out infrared scan to lower zone simultaneously and surveys;
After the infrared temperature check instrument of scan-type noncontact scans measured's forehead surface temperature, the forehead surface temperature is scaled body temperature through instrument internal.
After body temperature has been surveyed, if desired, can judge, surpass threshold value and then send sound, light warning by the hummer and the alarm lamp that are contained on scan-type noncontact infrared temperature check instrument inside and the shell by the alarm threshold value of setting.
In order to make the alarm temperature difference under the different situations, can before scanning, set the high temperature and the low-temperature warning threshold value of the infrared temperature check instrument of scan-type noncontact by keyboard and display.
For further accurate thermometric, can carry out the temperature repetition measurement with the infrared thermometer body of hand-held to being scanned the measured that the infrared temperature check instrument of formula noncontact is reported to the police.
The invention has the advantages that: 1. the infrared temperature monitor of scan-type noncontact that is provided, do not contact human body, can measure skin temperature from 1.5 meters of human bodies fast with interior, the reaction time was less than 1 second.2. the infrared temperature monitor of scan-type 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 scan-type 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%.
