Automatic meter reading method employing broadband carrier communication module

Abstract

The invention discloses an automatic meter reading method employing a broadband carrier communication module, and the method comprises the steps: performing the automatic networking according to a command start concentrator of a concentrator main reading module and a broadband carrier on an intelligent electric meter; starting the reading of the meter after the completing of networking; selectingroute reading when the concentrator just reads the data of several stations; performing the route reading according to the route path of a target address; starting the concurrent reading when the concentrator needs the data of a plurality of stations, and performing the concurrent reading. A broadband carrier module employed in the method is installed on the intelligent electric meter, and achieves the communication connection with the broadband carrier communication module on the concentrator. The broadband carrier module can achieve the power line networking, full-dynamic routing, is high insafety and reliability, is high in communication rate, and can safely and stably read the data in the electric meter.

Description

technical field [0001] The invention belongs to the technical field of automatic meter reading and relates to an automatic meter reading method using a broadband carrier communication module. Background technique [0002] With the continuous development of industrial automation, the traditional manual regular meter reading is time-consuming and laborious, which can no longer meet the needs of the current national grid construction. Automated meter reading can save manpower, improve work efficiency, and maximize economic benefits. The automatic meter reading currently used mainly includes wireless public network GPRS meter reading, power line carrier meter reading, micro-power wireless ad hoc network meter reading, etc. The power line carrier meter reading ad hoc network adopts the power line broadband carrier communication technology, and the electric energy meter, the collector and the concentrator form a meter reading network. When in use, the master copy module of the c...

However, in practical applications, the channel is not ideal for data communication, and it is a very unstable transmission channel, which is manifested in significant noise and severe signal attenuation, which makes some nodes fail to route or cannot communicate with the node through the routing path. to communicate

In this case, the use of routing meter reading will fail
