Abstract

The invention relates to a method for automatically reading electric quantity data in a multi-electric energy meter system, which is used for improving the reading efficiency of the electric quantity data in the multi-electric energy meter system. The invention adopts the technical scheme that each electric energy meter in the system delays the delivery of the identity identification code and theelectric quantity value of the electric energy meter to an infrared meter reader, the length of the delay time is the product of a remainder obtained by using the output value of a random code generator in each electric energy meter for dividing the doubled total of the electric energy meter and a delay factor. The method utilizes the random code to determine the delay time for uploading the dataof each electric energy meter to enable the data uploading time of the electric energy meters to generate difference so that the phenomenon of data congestion generated by simultaneously uploading the data of multiple electric energy meters is avoided, and the automatic reading of the electric quantity data in a multi-electric energy meter system is realized. The method can reduce the labor intensity of meter reading personnel and greatly improve the meter reading efficiency.

Description

Technical field

[0001] The invention relates to an infrared meter reading method, which can realize automatic reporting of the electric quantity data of multiple electric (energy) meters in an electric meter box. Background technique

[0002] With the increasing development of the power supply industry and the rapid advancement of science and technology, meter reading technology is constantly improving. At present, the more advanced meter reading method is to use infrared meter reader to read and report electricity meter data. The prerequisite for this meter reading method is to install an electronic billing electric energy meter with a microprocessor as the core device and an infrared communication circuit in the line. When reading the meter, first input the identity of the electric meter to the infrared meter reader. Then the infrared meter reader sends an infrared meter reading signal to the electric energy meter. After receiving this signal, the electric energy meter transmi...
