Problems solved by technology

However, due to the large number of resident users, there are often hundreds of thousands or even millions of users in an area, and each household has multiple meters, which puts a huge pressure on the meter file maintenance of the remote meter reading system. The operation and maintenance personnel check the files on site. Large volume, low work efficiency

Embodiment Construction

[0025] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] An active sensing method for water, gas, and heat meters used in full-duplex channels uses the principle that "full-duplex meters can actively report information", such as figure 1 Shown, the present invention comprises the following steps

[0027] S1: start table search work;

[0028] a. After power on for the first time, issue a full-volume search command;

[0029] b. Start the incremental meter search command after the daily meter reading work is over.

[0030] S2: The corresponding meter returns the meter reading data after receiving the command;

[0031] In this step, the meter needs to judge and return the meter reading data, but the following conditions must be met:

[0032] a. If it is an incremental meter search command, and the meter has not received a meter reading command for more than 24 hours, that is, the me...

Abstract

The invention provides a water, gas and heat meter active sensing method for full-duplex channels and relates to a meter reading method. Meter file maintenance of a remote meter reading system has huge pressure at present. The method comprises the following steps: 1) meter search operation is started, and a collector or a concentrator sends a meter search command; 2) a meter judges whether to respond to the command and returns meter reading data when receiving the meter search command, and the meter delays randomly, responds to the collector and returns the meter reading data if failing to be read by the collector in 24 hours or longer; 3) the collector submits a response message from the meter to the concentrator after receiving the response message from the meter; 4) the concentrator performs filing based on completed meter information; 5) the concentrator submits new meter information to a main station, and the main station performs meter filing, and the corresponding meter is managed by an optimal meter management concentrator. With adoption of the technical scheme, meter files can be managed automatically, active sensing of the water, gas and heat meters is achieved, the workload of operation and maintenance workers for file checking in site is reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to a meter reading method, in particular to an active sensing method for water, gas and heat meters used in full-duplex channels. Background technique [0002] With the continuous advancement of remote data collection technology for smart electricity meters, smart water meters, and gas meters for residential users, many places now have multi-meter data joint collection of "electricity, water, gas, and heat" to provide energy consumption for households. Analysis provides the basic conditions. However, due to the large number of resident users, there are often hundreds of thousands or even millions of users in an area, and each household has multiple meters, which puts a huge pressure on the meter file maintenance of the remote meter reading system. The operation and maintenance personnel check the files on site. The quantity is large and the work efficiency is low. Contents of the invention [0003] The technical problem to be ...
