Code matching method and system based on short-distance wireless switch

The invention discloses a code matching method and system based on a short-distance wireless switch, and relates to the technical field of remote control switches, in particular to a code matching method and system which are used for establishing the corresponding relation between the wireless switch and controlled LED light equipment, namely code matching, and only a remote controller after code matching can control the light equipment subjected to code matching. The code matching method comprises the following steps: only when a code matching button arranged on the remote controller is pressed down, the remote controller can send a code matching signal; a receiving end judges whether rssi reaches a threshold value after receiving the code matching signal, code matching is carried out only when the rssi reaches a specific threshold value, the ID of the remote controller is recorded, and light flickers for a specific number of times to serve as a response of successful code matching; only when the distance be
