technical field

The utility model relates to an electricity consumption information collection technology, in particular to an electricity consumption information collection device based on an ad hoc network and a power line network.

Background technique

At present, the collection of electricity consumption information is mainly realized by relying on the electricity consumption information collection network. Under the current technical conditions, due to the limitation of its own structure, the electricity consumption information collection network generally has the following two problems: First, the existing electricity consumption information collection network uses a single type of transmission medium (such as optical fiber), resulting in its There are problems such as difficult wiring, large amount of engineering for rerouting, easily damaged and immovable lines. Second, the existing electricity consumption information collection network lacks a unified network topology, resulting in unstable operation and poor reliability. Based on this, it is necessary to invent a brand-new electricity consumption information collection network to solve the problems of the existing electricity consumption information collection network, such as difficult wiring, large amount of rerouting, easily damaged lines, immovability, unstable operation, and poor reliability. .
