Problems solved by technology

The existing general practice is to use natural light, but due to the inconsistent natural light intensity at different times of the day, it is impossible to test the infrared communication performance in a laboratory environment around the clock. Most of the time, the detection time per day is only about 4 hours. On cloudy and light rainy days and at night, the detection cannot be performed at any time, the accuracy of the detection cannot be guaranteed, and it will not be affected by the interference of external light changes for a long time

Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] Infrared communication detection has high requirements on the optical environment, especially the detection of natural light interference on infrared communication, which is the key to detection. Because natural light changes with the change of weather and events and cannot be controlled artificially, in order to achieve the purpose of detection, the inventor quantifies the interference intensity of natural light on infrared communication by analyzing natural light and infrared spectrum, and detects the interference of natural light on infrared communication by simulating natural light interference.

[0018] Such as figure 1 As shown, the sensitivity of infrared reception is inconsistent at different wavelengths, and the wavelength corresponding to the hig...

Abstract

The invention provides a natural light interference simulation method for infrared communication detection. The optical filtering characteristics of an infrared communication device are used, by detecting the interference of natural light to infrared communication, an algorithm is used to control the brightness of an incandescent lamp to simulate the interference intensity of the natural light tothe infrared communication, and therefore, the purpose of truly simulating the interference of the natural light to the infrared communication is achieved. In this way, the infrared communication detection of instrument equipment is not affected by a natural environment, and long-time detection can be performed in a laboratory at any time. The accuracy of the infrared communication detection is greatly improved, and the method of the invention has the advantages of the simple structure of a system, easy implementation, precise control process and good operability.

Description

technical field [0001] The invention relates to a light interference simulation method. Background technique [0002] The detection of infrared communication has reached a certain level in the field of military research at home and abroad, and its detection equipment is very expensive and complicated. In the civil field, such as electric meters, its infrared communication detection is very crude and unscientific. The existing general practice is to use natural light, but due to the inconsistent natural light intensity at different times of the day, it is impossible to test the infrared communication performance in a laboratory environment around the clock. Most of the time, the detection time per day is only about 4 hours. In cloudy and light rainy days and at night, the detection cannot be performed at any time, the accuracy of the detection cannot be guaranteed, and it will not be affected by the interference of external light changes for a long time.
