The invention provides a method for realizing automatic address allocation based on RS485. A host device and a plurality of slave devices are provided. The host device and the slave devices are in communication connection based on RS485 communication standards, and the method comprises the following steps: S1, the host device issuing a search command, searching whether the slave equipment with the unallocated address exists or not; if so, turning to the step S2; if not, returning to the step S1; S2, the host device issuing an address message including address information to indicate the slave device to preempt the address information, wherein the slave device is not allocated with an address; and S3, after receiving feedback information of the unique slave device preempting the address information, the host device allocating the address information to the slave device. According to the RS485-based method for realizing automatic address allocation, the labor cost is greatly reduced, the production efficiency is improved, and intelligent testing is realized.
