Abstract

The invention discloses a dual-mode communication chip and relates to an information collecting and controlling system in need of low-power wireless and power line communication. The dual-mode communication chip comprises a wireless communication unit, a carrier communication unit, an internal bus and an external bus. The wireless communication unit and carrier communication unit are connected with the external bus through the internal bus, and the wireless communication unit, the carrier communication unit, the internal bus and the external bus are integrated in a single chip. By the arrangement, the defects of low-voltage carrier and micropower wireless are overcome, and success rate of meter reading is greatly improved; an electricity information collecting system is truly practical since circuits of the same are simple in design, performance is improved and cost is reduced.

Description

technical field [0001] The invention relates to an information collection and control system for low-power wireless and power line communication, especially suitable for remote meter reading (AMR) systems such as electric meters, water meters, and gas meters, as well as smart home control, street lamp control, and other fields. Background technique [0002] At present, the national electric power system uses more communication technologies in the downlink communication of the electricity information collection system, including low-voltage carrier wave and micro-power wireless. These two communication methods have obvious disadvantages: the communication environment of low-voltage power lines is harsh, Carrier communication is easily affected by grid impedance changes, noise, harmonics, etc., resulting in unreliable communication, and the one-time actual reading rate is only 95%; micro-power wireless communication is affected by transmission distance, building blockage, wirel...
