Problems solved by technology

[0003] After the infrared sensor is produced as a finished product, it needs to be tested for its detection accuracy and service life. At present, there is no equipment that can automatically test the long-term operation of the infrared sensor. Instead, it relies on manual testing and manually activates the infrared device. Manually count the number of activations, test results, failure rate, etc., and require manual on-duty. This test method relies on manual operations, so the test efficiency is low, and it is impossible to accurately control the activation interval, activation frequency, etc.

Abstract

The invention relates to the field of infrared detection, and discloses a device for testing an infrared sensor. The device includes: a rotating part, used to drive the infrared sensor to be tested to rotate; a motor module, connected to the rotating part, used to drive the rotating part The part rotates; the signal detection module is used to detect the signal sent by the infrared sensor under test when it detects an infrared signal; and the counting module is used to detect the number of rotations of the rotating part and the The number of times the infrared sensor emits a signal is counted. The device rotates periodically through the rotating part, and detects the signal sent when the infrared sensor detects the infrared signal, and can automatically test the performance of the infrared sensor.

Description

technical field [0001] The invention relates to the field of infrared detection, in particular to a device for testing infrared sensors. Background technique [0002] All objects that exist in nature, such as human beings, fire, ice, etc., all emit infrared rays, but their wavelengths are different due to the temperature of the object. For example, the body temperature of the human body is about 36-37°C, which emits far infrared rays with a peak value of 9-10 microns, and objects heated to 400-700°C can emit mid-infrared rays with a peak value of 3-5 microns. Infrared sensing system is a measurement system using this kind of infrared as the medium, which can be divided into photon detectors and thermal detectors according to the detection mechanism. [0003] After the infrared sensor is produced as a finished product, it needs to be tested for its detection accuracy and service life. At present, there is no equipment that can automatically test the long-term operation of th...
