Temperature acquisition equipment

Abstract

Temperature acquisition equipment comprises an intelligent mainboard, a display screen, an infrared temperature acquisition device, a distance acquisition device, a power adapter, a shell and the like. The display screen, the infrared temperature acquisition device, the distance acquisition device and the power adapter are electrically connected with the intelligent mainboard. The infrared temperature acquisition device (including a temperature measuring sensor) and a distance measuring device (including a distance measuring sensor) are installed at the front end of a temperature measuring device main body side by side. The intelligent mainboard can comprehensively receive and process data such as the temperature and the distance, then further correct the temperature through parameters such as the field angle and the distance, and send corrected temperature information, distance information and field information to the display screen to be displayed.

Description

technical field [0001] The invention belongs to the field of temperature measurement, in particular to a temperature detector. Background technique [0002] Thermometers are essential items in daily life. At present, there are three common thermometers: mercury thermometer, digital thermometer and infrared thermometer. Among them, mercury thermometers have the disadvantages of long measurement time, difficult to read, and potential dangers, such as fragile glass and toxic volatilization of mercury; digital thermometers are easily affected by ambient temperature, and the measurement accuracy will be reduced when the ambient temperature difference is large. The infrared thermometer uses the principle of black radiation to measure the temperature reading. The infrared sensor it uses only absorbs the infrared rays radiated by the object without emitting any rays to the outside world. It senses the temperature through a non-contact method, and has the advantages of fast measurem...

Problems solved by technology

[0004] At present, most infrared temperature measurement devices use handheld devices to manually adjust the distance to the object, and the manual button triggers the test. In this way, since the user relies on visual inspection to ensure the temperature measurement distance, the distance is not accurate, so there may be differences in the measurement distance and direction of different people. There may be a problem that the test is not accurate due to improper operation

At the same time, due to the different temperature measurement distances in various occasions, the error is greater

[0005] An important reason for the error is that when the infrared thermometer is in use, the size of the infrared field of view changes with the change of the measurement distance. According to the focus of the optical lens, the change law is also different, which can generally be understood as When the field of view is large, the average temperature takes more data, which may include the temperature of irrelevant objects around the target object. , causing an error
