Method for multi-channel self-adaptive switch during terminal communication

Abstract

The invention relates to a method for multi-channel self-adaptive switch during terminal communication, in particular relating to a method for self-adaptive switch of a wireless channel and an Ethernet channel. The method comprises: a terminal automatically detects a wireless communication module and an Ethernet physical link channel, automatically judges the parametric model of Ethernet, and switches to the Ethernet channel when detecting that the Ethernet channel is available (or else switches to the wireless channel). The method has the following beneficial effects: the real-time detection of the wireless channel and the Ethernet channel can be realized, the switching is automatically carried out according to detection results, the fast switch actions are realized in the whole process, the self adaptability to two types of network channels is fully realized, and the manual intervention is avoided; and when the Ethernet is available, the Ethernet channel is utilized preferably; because the Ethernet channel is adopted, the network bandwidth can be greatly expanded, the network time delay is reduced, and meanwhile the consideration of flow is ensured to be unnecessary, thereby reducing a great deal of communication cost; and when the Ethernet is not available, the wireless module is started for utilizing the wireless channel for communication, so that the smooth communication between the terminal and a master station can be ensured.

Description

technical field [0001] The invention relates to a method for self-adaptive switching of multiple channels in terminal communication, more specifically, a method for self-adaptive switching of wireless channels and Ethernet channels in terminal communication. Background technique [0002] In the electricity consumption information collection system of power users, the collection terminal needs to transmit the collected power user data to the main station of the system. Busy, and most of the terminals currently exchange data with the main station through GPRS or CDMA wireless public network, but in some developed areas, Ethernet communication methods such as power optical fiber or ADSL have been realized. At present, when the terminal selects a wireless or Ethernet communication channel, it cannot automatically detect and judge redundant multi-channels. It is necessary for the operator or maintenance personnel of the main station to manually set the terminal on site, which is ...
