Power consumption information acquisition terminal public and private network communication module and switching method

Abstract

The invention discloses a power consumption information acquisition terminal public and private network communication module and a switching method. The communication module comprises three states in a working process: an initial state, a public network access state and a private network access state, and automatic transfer among the three states can be realized. The adopted public and private network communication module can provide a network link which is more reliable than pure public network access or pure private network access for a power consumption information acquisition terminal, a private network signal is preferentially searched to select a private network to access the network, and then self-adaptive switching is performed between the private network and the public network, so that the online rate of the acquisition terminal and the success rate of power consumption information acquisition are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power internet of things, and specifically relates to a public-private network switching method of a public-private network communication module of a power consumption information acquisition terminal with preferential access to a private network and self-adaptive switching, and also relates to a power consumption information collection method Terminal public and private network communication module. Background technique [0002] With the continuous advancement of smart grid construction, grid companies have installed on-site measurement and collection terminals such as smart meters and concentrators on the user side. Periodic or active reporting of frozen value, total demand, voltage, active power, reactive power, and power quality; it strongly supports the accurate and timely settlement of user electricity bills, replaces the original manual meter reading method, and effectively improves the en...
