摘要

Provided are a method of achieving free-pairing wireless door lock based on DIP switch, a wireless door lock and a communication method for the wireless door lock. The method of achieving free-pairing wireless door lock based on DIP switch specifically includes: step 1, selecting for a wireless door lock a wireless chip which supports data modulation, wherein a data field of a transmission packet includes a lock address bit field and an area code field; step 2, providing, a built-in multi-bit DIP switch for the wireless door lock in terms of hardware, in which case the multi-bit DIP switch is directly connected with an input pin of the central processing unit of the wireless door lock; step 3, installing an embedded software in central processing unit of the wireless door lock; and step 4, matching a DIP switch address with a room number during installation of the wireless door lock.
