Problems solved by technology
[0003] However, with the application and popularization of intelligent equipment, various electrical appliances are widely used in the family, which increases the complex electromagnetic environment of electrical equipment, making the remote control function unable to work normally in a specific environment, and such failures cannot be found in conventional functional tests. At the same time, all kinds of consumer products are heating up, and all walks of life are mining costs. Cost control has obviously become a key factor for market survival, so various product chains are competing to explore, even at the expense of product performance and indicators; as far as infrared receivers are concerned , the products on the market are uneven, and the performance indicators are also different.

The invention relates to the technical field of electronic product testing, and achieves the purposes by providing a method for testing the electromagnetic interference of an infrared receiving head.The method comprises the following steps: firstly, adjusting lighting equipment according to the center frequency of an incoming carrier of the infrared receiving head to form a light interference source and an electromagnetic interference source; then, placing the lighting equipment right above the infrared receiving head to be tested; finally, detecting the receiving function of the infrared receiving head through a remote control. Through use of lighting, an electromagnetic interference environment is restored, a using environment of a user is simulated, and the infrared receiving head is detected and controlled, so that blind increase in the materialization cost is avoided, and thus the infrared receiving head is guaranteed to meet the market demand and the market competitiveness is improved while the cost of the infrared receiving head is reasonably controlled; meanwhile, the lighting equipment is easy to manufacture, so that testing of the electromagnetic interference of the infrared receiving head is low in cost and easy to operate.
Description
technical field [0001] The invention relates to the technical field of electronic product testing, in particular to an electromagnetic interference testing method of an infrared receiving head. Background technique [0002] With the development of electronic technology and the improvement of the living standards of the general public, every family uses more and more telecommunication equipment, mobile phones, energy-saving lamps, electronic ballast fluorescent lamps, household appliances, etc., and almost all related household appliances require remote controls. Most of the equipped remote controllers use an infrared receiving head for receiving; the working principle of this infrared receiving head is realized by identifying the band signal code of the corresponding frequency and then decoding it. When the remote control device sends a fixed frequency When the signal is encoded in the band, the infrared receiving head will recognize it, and control the electrical appliance ...
