Method for setting addresses of slave devices in communication network

摘要

A method for setting addresses of slave devices in a communication network is provided. In the communication network, a master device identifies address-collided slave devices and requests the address-collided slave devices to return their unique identification data. The master device sets addresses of the address-collided slave devices so that each of the slave devices in the communication network has a different address from one another.

1. A method for setting addresses of slave devices in a communication network, the communication network comprising a master device and a plurality of slave devices, the master device communicating with each of the slave devices according to an address of each of the slave device, the setting method comprising:
a) in response to a request from the master device, each of the slave devices responding to the master device according to its address; b) identifying a collision address group and an unused address group, the collision address group including a same address stored in at least two of the slave devices, and the unused address group including a plurality of addresses that are not stored in any of the slave addresses; c) selecting a first address from the collision address group; d) randomly returning a first unique identification data from the first slave device storing the first address to the master device within a predetermined period; e) the master device communicating with the first slave device to set a first unused address from the unused address group to the first slave device according to the first unique identification data; and f) repeating the steps (d) and (e) until the collision address group excludes the first address.
