Intelligent networking method based on arbitration-free bus

Abstract

The invention discloses an intelligent networking method based on an arbitration-free bus. The intelligent networking method comprises the following steps: (1) when all networking equipment is started and enters respective delaying, sending roll calling messages when the delaying is finished, and determining a hoist according to a rule; (2) sending the roll calling messages by the host according to an initial ID sequence from small to large, and responding the received roll calling messages consistent to the ID when the secondary delaying of the host is finished; and networking according to the rule. The method disclosed by the invention has high intelligence and reliability, does not consume hardware cost and is free of maintenance; the method has a communication fault self-diagnosis function and really realizes configuration-free and operation-free networking communication; the intelligent networking method is particularly suitable for the fields with bad maintenance fields, complicated configuration and uneven quality of constructors.

Description

technical field [0001] The invention belongs to the field of networking communication, and relates to a communication networking method. Background technique [0002] At present, the conventional method of non-arbitration bus networking is: before the device networking, assign addresses to each device, and assign one as the host, and the host is in charge of the communication dominance of the network. The advantage of this method is that the address setting is intuitive, and you can clearly know which device corresponds to which address. The disadvantage is that once the number of devices in the network is large, the setting workload will also double. Error, after power-on later, it is found that there is a conflict, and it must be re-checked and reset. [0003] In the existing method, after the device is powered on, the self-organizing network is performed according to the address to complete the networking operation. If any device is damaged during operation, it needs to ...

The advantage of this method is that the address setting is intuitive, and you can clearly know which device corresponds to which address. The disadvantage is that once the number of devices in the network is large, the setting workload will also double. Error, after the power-on later found that there is a conflict, you must re-check and reset

[0004] 1. If you cannot know the address of each current device, you cannot set a valid address for the new device, which is very likely to cause address conflicts, network collapse or address setting overflow and other problems

[0005] 2. During the operation of networking equipment, if you need to add new equipment, you will find the same problem as Question 1, you must know the addresses of all current equipment, otherwise the networking operation cannot be completed, or even the networking crashes

[0006] 3. During the operation of the networking equipment, if the host fails and needs to be replaced, during the host failure, the entire networking network collapses due to lack of host scheduling

[0007] 4. During the actual on-site construction and operation, due to the poor site conditions; the construction personnel do not have the knowledge of setting up the network or are afraid of trouble; in many cases, the equipment is powered on and running, but the network is not running, wasting electric energy in vain. play its due social value
