Micro bus gateway suitable for intelligent meter reading system

Abstract

The invention discloses a micro bus gateway suitable for an intelligent meter reading system. The micro bus gateway comprises a CPU main controller, a remote communication module, more than one communication control switch capable of selecting communication ports, more than one power switch and a power manager, wherein the communication control switch is a one-in and four-out electronic switch site selector; the power supply end of the CPU main controller is connected with the power supply manager, the power supply control end of the CPU main controller is electrically connected with one power supply switch, the general programmable input / output port GPIO of the CPU main controller is connected with the input end of the communication control switch, each output end of the communication control switch is connected with one intelligent water meter, the output of one communication control switch is connected with more than one intelligent water meter to form a group of meter reading units, each group of meter reading units is connected with the power manager through one power switch, and the intelligent water meters on the same group of meter reading units are connected with the same power switch. The structure saves the equipment cost.

Description

technical field [0001] The invention relates to the technical field of intelligent meter reading, in particular to a miniature bus gateway suitable for an intelligent meter reading system. Background technique [0002] The water use policy of one household, one meter, the water use situation is realized through the regular copying of the water meter readings to realize the management of water use. Most of the deployment of water meters in my country is handled by placing the user water meters on the first floor in Shuijingfang or underground inspection wells. There are more than 3-10 water meters in the centralized place, which is relatively centralized and absolutely decentralized. [0003] Currently, there are two mainstream communication modes for smart meter reading: [0004] 1. Each water meter has a communication module, which collects and sends independently; although this installation method is flexible and suitable for different water meter installation environments...
