Method for automatically reading electric quantity data in multi-electric energy meter system

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 the automatic reporting of electric quantity data of multiple electric (energy) meters in the electric meter box. Background technique [0002] With the increasing development of the power supply industry and the rapid advancement of science and technology, the meter reading technology is also constantly improving. The more advanced meter reading method is to use the infrared meter reading device to read the meter data. The premise of using 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 circuit. When reading the meter, first input the identity of the electric energy meter to the infrared meter reading device. code, and then the infrared meter reading device sends an infrared meter reading signal to the electric energy meter. After receiving the signal, th...

Problems solved by technology

This method of meter reading is fast and the data is easy to store, but the existing infrared meter reading method can only read the data of one electric energy meter per operation, which is suitable for the situation where there is only one electric energy meter in the electric meter box, and manual labor is required each time. Enter the identification code of the electric energy meter, which limits the efficiency of copying

When there are 6 or even more meters in the meter box, it is difficult to copy the data, let alone copy the data of multiple meters at the same time, because the infrared meter reading device sends infrared meter reading to the electric energy meter After receiving the signal, each meter will transmit power data to the infrared meter reading device at the same time, and there will be interference between these data, and data congestion will occur, so that the data of each meter cannot be reported successfully.
