Method for power management of wireless remote meter reading system

Abstract

The invention relates to a method for power management of a wireless remote meter reading system. The method is especially suitable for the wireless remote meter reading system which is composed of wireless intelligent instruments and apparatuses and a meter reading device. The wireless intelligent instruments and apparatuses have onsite serial numbers ID2 except the electronic label numbers ID1 set at the moment of leaving factory; the onsite serial numbers ID2 are started from No.1 to No.n, wherein n is the total number of the wireless intelligent instruments and apparatuses managed by the meter reading device; the meter reading instruction is sent in the sequence of the ID2; the wireless intelligent instruments and apparatuses determine the sleep mode thereof according to a comparison result of the data of the onsite serial numbers ID2 received at the first time and the allocated onsite serial numbers ID2; the effects of reducing the power consumption of the wireless intelligent instruments and apparatuses and prolonging the service life of built-in batteries can be achieved in the manner of causing instruments and apparatuses to enter an ultra-low power consumption sleep state as much as possible in one meter reading period.

Description

technical field [0001] The invention relates to a method for power supply management of a wireless remote meter reading system, and is particularly suitable for a wireless remote meter reading system composed of wireless intelligent instruments, meters and meter reading system equipment. Background technique [0002] With the development of technology and the improvement of people's living standards, intelligent remote meter reading has become the demand of modern society. The remote meter reading system has changed the original manual meter reading mode and brought great convenience to users and management departments. The initial pulse measurement and split-line meter reading system, to the wired digital transmission bus meter reading system, and to the wireless digital transmission meter reading system have developed rapidly. [0003] The wireless remote meter reading system consists of wireless meter reading system equipment, wireless smart instruments and meters, of whi...

AI Technical Summary

Problems solved by technology

[0003] The wireless remote meter reading system consists of wireless meter reading system equipment, wireless smart instruments and meters, of which wireless smart instruments and meters are generally powered by batteries, and the wireless receiving and sending modules installed in wireless smart instruments and meters are usually in a low-power sleep mode , is awakened by the command sent by the wireless meter reading system equipment. In the sleep mode, the wireless smart instrument and the meter consume very little energy. Usually the current parameter is in the microampere level. Once awakened, the wireless smart instrument and the meter consume less energy. The energy will increase tens of thousands of times, and the current will usually increase to the order of tens of milliamps. A small local system of a meter reading system usually consists of a wireless meter reading system device, several wireless smart instruments, When the wireless meter reading system equipment needs to read the data of a certain wireless smart instrument or meter in the system, other wireless smart instruments and meters in the same channel will respond to the signal sent by the wireless meter reading system device, and will start from sleep mode. Mode wake-up, enter the working state, it will greatly consume the energy of the built-in battery, reduce the life of the battery, and reduce the life of the system

In order to improve the life of the system, the usual method is to increase the battery capacity, which not only increases the system cost, but also makes it difficult to solve the practical difficulties, which leads to the low reliability of the wireless meter reading system and inhibits the promotion and use of the wireless meter reading system.
