In view of the disadvantages of existing beacon frequency modification, such as computer, tedious operation and poor convenience, this paper uses STC89C52 single-chip microcomputer as the core control component, uses infrared remote controller as the input device, designs a convenient beacon sphere frequency modifier based on infrared remote control, and completes the production of the prototype. In the process of releasing the beacon sphere many times, we have obtained the practical application shows that the beacon point frequency modifier developed in this paper is easy to operate and carry.
