Description

technical field [0001] The invention relates to the technical field of combination locks, in particular to an infrared remote control combination lock based on a single-chip microcomputer. Background technique [0002] With the rapid development of the electronic technology industry, the ancient mechanical locks are facing great challenges. Combining computer applications and the development of single-chip microcomputers, various combination locks have appeared on the market. At present, the combination lock industry in my country has begun to take shape. Technology The level has also been greatly improved, but it is undeniable that there is still a big gap between the overall development level of my country's related industries and foreign countries. Advanced large-scale equipment mainly depends on imports, and the export volume is very small. The import volume is roughly equal to the total output value. , which is far from that of developed countries. From the perspective o...
