Disclosed by the present application are a method, master device and system for data communication. The method comprises: initiating a communication signal to an interface in an interface module; when response information from a slave device connected in the interface is received, adding physical ID information of the interface into an online queue, wherein the probability that interfaces in the online queue is subsequently initiated by the communication signal is higher than that of interfaces in an idle queue; and receiving data information transmitted by the slave device in the interface. The data communication master device of the present application comprises a communication signal initiation unit, an online interface identification unit and a data information receiving unit corresponding to the implementation of steps of the described method. Therefore, the communication network for multiple slave devices and a master device has high communication efficiency.
