Wireless automatic meter reading system based on NGB (Next Generation Broadcasting) and control method thereof

Abstract

The invention discloses a wireless automatic meter reading system based on an NGB (Next Generation Broadcasting) and a control method thereof, belonging to the field of digital information transmission and processing based on a broadcasting and television network and a short-distance wireless communication network. The system comprises an information acquiring device, an information receiving and transmitting device and an information processing device, wherein the information acquiring device is used for acquiring avometer information and transmitting the acquired avometer information to the information receiving and transmitting device; the information receiving and transmitting device is used for receiving the avometer information and transmitting the avometer information to the information processing device through a broadcasting and TV wired bidirectional network; the information processing device is used for transmitting the received avometer information to an information processing center in a network; and the information processing center performs bidirectional communication with the information receiving and transmitting device through the broadcasting and TV wired bidirectional network. In the invention, a wireless receiving and transmitting module is connected to the traditional interface of a set-top box or a digital television, and a user operation interface continues to use the conventional television interaction charging system, so that a user can inquire information on an avometer, payment, account bills and the like through the television.

Description

technical field [0001] The invention relates to a wireless automatic meter reading system based on NGB (Next Generation Broadcasting Network) and a control method thereof, and belongs to the field of digital information transmission and processing based on a broadcasting network and a short-distance wireless communication network. Background technique [0002] The wireless meter reading system is developed on the basis of electronic water and electricity meters, and its concept was put forward more than ten years ago, and some related universities and companies have made many attempts for the wireless meter reading system, but so far There is no large-scale popularization at home and abroad. Specific to wireless water meters, there are mainly the following problems that plague researchers and consumers: measurement errors of electronic water meters, power consumption of electronic water meters, reliability of indoor wireless transmission, meter reading methods, and remote hi...

Problems solved by technology

Most of the wireless water meter systems reported in China are mobile networks based on telecommunications, which requires a mobile phone module at the water meter end to participate in sending and receiving. It is a waste of hardware resources and network resources, and the operating cost is also high.

In order to solve the above problems, some researchers proposed a meter reading system based on a small-scale centralized wireless system, which integrated a relatively simple wireless module on the electronic water meter, and placed a relatively high-power wireless transceiver on the roof of the building. system, and the water meter transcription personnel drive the car equipped with the wireless transceiver system to pass through the community to concentrate on copying the water meter. This method of wirelessly copying the water meter consumes relatively high power consumption for the wireless module of the electronic water meter, and due to the need for water meter copying It is relatively cumbersome for people to drive cars in various districts
