Abstract

The invention discloses an electricity information acquisition system based on dual-mode communication and a method thereof; the system includes a far-end master station, a concentrator and an intelligent electric energy meter; the far-end master station is used for acquisition and management of system electric power user electricity information through various wired or wireless communication channels, and is used for data exchange with the concentrator through a remote communication module; the concentrator is provided with a dual-mode communication module, and is used for acquiring intelligent electric energy meter data information and operation states through the dual-mode communication module, achieving local acquisition and monitoring of the electricity information, and uploading the local electric meter data information to the far-end master station through the remote communication module; the intelligent electric energy meter is provided with a dual-mode communication module and is responsible for electricity information measurement, data processing, real-time monitoring, automatic control and information exchange. The communication problem generated when a fault occurs due to single use of a micro power wireless or power line is avoided, the consumed power of a dual-mode communication chip is reduced, and the reliability of the communication is ensured.

Description

technical field [0001] The invention relates to a dual-mode communication-based electricity consumption information collection system and a method thereof, belonging to the technical field of communication. Background technique [0002] Both low-voltage power line carrier communication and micro-power wireless communication are widely used in power systems, and each has advantages and disadvantages. Low-voltage power line carrier communication belongs to wired communication technology, and its channel characteristics are affected by factors such as distribution network structure, power load, interference and noise; while wireless communication technology is greatly affected by geographical environment and weather factors. Therefore, the two The channel characteristics have complementary properties. The research on power line carrier and wireless converged communication technology is conducive to the deployment of power line carrier and wireless dual-channel or heterogeneous...

Problems solved by technology

[0003] The existing domestic dual-mode communication technology uses the main and auxiliary mode, that is, one of the communication methods is the main channel, and the other communication method is used as the "bridge". Only individual nodes replace the dual-mode communication module, and the dual-mode communication technology is applied , the construction technical requirements are relatively high, and bridge nodes need to be manually designated, which will inevitably increase the cost of on-site engineering implementation; there are obvious differences between the application scenarios of the existing dual-mode communication ad hoc network in China and the existing typical power information networking forms, and the same station area It is difficult to manage mixed communication applications by installing carrier communication modules, micro-power communication modules, and dual-mode communication modules at the same time, which will affect the efficiency of equipment installation, commissioning, and maintenance in the power sector; although there are currently related communication products, the technology of each product The schemes are quite different, the product performance is uneven, the signals interfere with each other, and there is no unified dual-mode communication technology standard for power consumption information collection, and the modules cannot be interconnected, which will limit the market promotion of dual-mode communication modules
