Problems solved by technology

The performance test method commonly used in the prior art relies on the real scene test. If the test range of the infrared sensor reaches 15m, in order to test the actual detection effect, it is necessary to build a real scene environment of about 15m*10m, which is extremely expensive and requires a lot of manpower and material resources to build a real environment

Abstract

The invention discloses a performance test method for an infrared sensor, and the method comprises the steps: carrying out the resetting of a rotating disc in response to a reset instruction; wherein the infrared sensor is loaded at the position of a rotating shaft of the turntable and rotates along with the turntable, and a teleconverter which does not rotate along with the turntable is arranged in front of the position of the infrared sensor; controlling the simulated heat source device to move according to a preset operation rate; in the motion process of the simulated heat source device, the detection result of the infrared sensor and the moving coordinate of the simulated heat source device are obtained at the same time; each time the angle of the turntable is adjusted, a detection result of the infrared sensor and a moving coordinate of the simulated heat source device are obtained; and determining a horizontal detection angle and a horizontal detection distance of the infrared sensor in the horizontal direction based on the detection result and the moving coordinate. The invention further discloses a performance testing device, equipment and system for the infrared sensor. By adopting the embodiment of the invention, the performance of the infrared sensor can be tested without building a large real scene test environment, and the cost is saved.

Description

technical field [0001] The invention relates to the field of infrared induction testing, in particular to a performance testing method, device, equipment and system of an infrared sensor. Background technique [0002] The infrared sensor is a sensor that uses infrared rays for data processing, and can control the operation of the drive device. Infrared sensors are commonly used in non-contact temperature measurement, gas composition analysis and non-destructive flaw detection, and are widely used in fields such as medicine, military affairs, space technology and environmental engineering. PIR (Passive Infra Red, human pyroelectric infrared sensor) is a kind of infrared sensor, which can find the abnormal temperature by measuring the thermal image of the human body surface temperature from a long distance. PIR is low in price and stable in technical performance. It is welcomed by the majority of users and professionals, and is widely used in various automatic control devices...
