Water-electricity-gas three-meter remote intelligent centralized meter reading system based on digital TV set-top box

Abstract

The present invention provides a water-electricity-gas meter remote intelligent integrated meter reading system based on the digital television set top box, including: a three meters information search display subsystem for searching and output the searched three meters information, achieving by the set top box and the television of each user; a three meters information storage processing subsystem, for storage and processing three meters information of each user, achieving by the logistics management center computer; a three meters information collecting subsystem, for collecting the three meters information of each user, achieving by the three meters information collector of each user. The invention achieves the interactive communication based on the communication centrum of the Cable DTV web by the logistics management center computer, the three meters information collector and the Cable DTV web. The present Cable DTV web having high quality substitutes for the traditional complex bus or private line to achieve signal communication, this makes the system have simple structure, convenient for install and implement, reducing the fault latency at the same time, enhancing the credibility of system.

Description

technical field [0001] The invention relates to the technical field of intelligent management of residential quarters, in particular to a system for realizing intelligent management of household water, electricity and gas meter information data by means of a digital TV set-top box. Background technique [0002] The intelligent three-meter remote centralized meter reading system in the building has been widely used in my country, and its communication methods can be summarized as bus (or dedicated line) communication and carrier communication. [0003] In the implementation of bus (or dedicated line) communication, each resident of the building must connect multiple dedicated communication lines to the three-meter remote centralized meter reading system. Therefore, using the bus (or dedicated line) communication method, the installation and implementation of the intelligent three-meter telephone network remote centralized meter reading system in the building is extremely comp...

AI Technical Summary

Problems solved by technology

Therefore, the installation and implementation of the intelligent three-meter telephone network remote centralized meter reading system in the building is extremely complicated by using the bus (or dedicated line) communication method, especially for buildings with a large number of residents, this problem is particularly prominent

In addition, when designing a new building, a dedicated channel must be reserved for its communication lines, which invisibly increases the construction cost; while the installation and implementation of the three-meter remote centralized meter reading system in the old building requires drilling holes through the wall, which is time-consuming and labor-intensive. , and hinder the beauty of the building

In addition, from a long-term point of view, there is still a major hidden danger in the three-meter remote centralized meter reading system using bus (or dedicated line) communication, that is, the maintenance and repair of dedicated communication lines

[0004] Using the carrier communication method, its signal quality and anti-interference ability depend to a large extent on the environment of the power network where it is located. The poor environment of the cable network will cause the carrier communication to be distorted to varying degrees.

Therefore, it is difficult to ensure that carrier communication can transmit data accurately in any power grid environment

[0005] In addition, the three-meter remote centralized meter reading system of bus (or special line) communication and carrier communication must have a set of complex coding and decoding circuits to realize the address coding and decoding of residents. The structure is complex and reduces the reliability of the system.
