Automatic switching method for power communication networks

Abstract

The invention relates to an automatic switching method for power communication networks. A detection terminal has a first network type connection mode and a second network type connection mode, and is connected with a first communication module and a second communication module, the front and rear ends of each of the first and second communication modules are respectively connected with a first switch and a second switch, the first switch is connected with the detection terminal, the second switch is connected with a remote receiving terminal, and first network type connection is established with a mobile communication base station by the first communication module; the first and second switches set the priority of the second network type to be high and the priority of the first network type to be low; the detection terminal uninterruptedly sends ping packets to the first and second switches regularly or irregularly for detection; linkage items are established on the first and second switches, when it is detected that the second network type does not accord with communication conditions, the priorities of the first and second network types are exchanged. According to the automatic switching method for the power communication networks, the connection network can be automatically switched in real time according to network conditions, thus ensuring smooth communication.

Description

technical field [0001] The present application relates to an automatic switching method of a power communication network. Background technique [0002] The current power communication network uses routers and switches to form a network, and channel redundancy is made when accessing. However, due to equipment limitations, one link needs to be interrupted to switch to another channel during channel switching. It cannot actively judge the network quality and perform automatic switching, and it does not have alarm measures. As a result, when the quality of a channel is poor (for example, although the channel is not broken, the actual bandwidth is far from enough), it cannot be automatically judged and switched. Or automatically switch without knowing when one channel is interrupted, and not know until another link is interrupted, resulting in network interruption. [0003] In the prior art, for switching between communication channels, the most commonly used method at present ...
