Problems solved by technology

[0019] In practical application, the above scheme has the following problems: the existing addressing scheme has poor maintainability, when the address of the slave node needs to be changed, it needs to be changed on site of the slave node, and the maintenance cost is high
[0020] The main reason for this situation is that the slave node address of the existing technical solution is set by the hardware

Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] First, the basic principle of the present invention will be described. In the scheme of the present invention, in the case of cascading networking of a master node and multiple slave nodes, the multiframe transmitted between the nodes carries information for address allocation, and each slave node obtains its own address allocation information from the received address allocation information. address. Since the solution of the invention does not depend on hardware to set the address, the difficulty of system maintenance is greatly reduced.

[0047] The topology structure of the addressing system of the cascaded network of the present invention is exactly the same as that of the prior art. It can be a chain network or a ring network. The system also include...

Abstract

This invention relates to communication field network and discloses one interact address finding system and its method to improve system sustainance and to lower cost without hardware setting from one main joint and multiple joint. The address finding system doesn't adopt hardware type and adds address dispatching through multiple frame.

Description

technical field [0001] The invention relates to networking in the field of communication, in particular to address allocation during networking in the field of communication. Background technique [0002] In various communication systems, cascade networking is a very common networking method. In a cascaded network, it can include a master node (MN for short) and multiple slave nodes (Slave Node, SN for short), and these nodes are connected to form a chain through the interface of the connection link. network or ring network. [0003] A schematic diagram of the system composition of a chain network composed of a master node and multiple slave nodes using a cascaded network is shown in figure 1 shown. Among them, the master node is represented by MN; there are n slave nodes, represented by SN0~SNn-1 respectively. [0004] A schematic diagram of the system composition of a chain network with two chains formed by a master node and multiple slave nodes using cascaded networki...
