Embodiment 1
[0029] A wireless smart meter meter reading system according to the present invention, such as figure 1 As shown, including smart meters, main network repeaters, subnet repeaters, collectors, concentrators, main network repeaters and master server. in,
[0030] The smart meter receives the copy management instruction forwarded by the subnet repeater of the subnet where it is located; and collects the usage data of the user according to the copy management command, and packs the usage data and the smart meter MAC address into a smart meter. Table user usage data and send it over wireless network.
[0031] The subnet repeater receives the reading management instruction forwarded by the collector, and forwards the reading management instruction to the smart meter of the subnet where it is located. receiving the smart meter user usage data sent by the smart meter and forwarding the usage data to the collector.
[0032] The collector is configured to establish a subnet, and assign...
Embodiment 2
[0041] As an embodiment of the present invention, on the basis of Embodiment 1, a handheld terminal is also included, and the handheld terminal sends information to the smart meter, the subnet repeater, the collector, the concentrator, and the The main network repeater sends the smart meter user usage data reading instruction; receives the smart meter, the subnet repeater, the collector, the concentrator, and the main network repeater. and store the smart meter user usage data. The user usage data of the smart meter can be directly read through the handheld terminal, which facilitates the management of the smart meter.
Embodiment 3
[0043] As an embodiment of the present invention, on the basis of any of the above embodiments, the smart meter actively collects and reports the user usage data of the smart meter at a period T, which facilitates the management of the entire system.

Abstract
The invention relates to a meter reading system of a wireless intelligent meter. The system comprises the intelligent meter, a subnet relay, a collector, a concentrator and a master station server, wherein the intelligent meter collects and sends data of use levels of intelligent meter users, the subnet relay transmits a reading management command and the data of the use levels of the intelligent meter users, the collector establishes a subnet, collects the data of the use levels of the intelligent meter users, and transmits the reading management command, the subnet relay transmits an ultrashort management command and the use levels of the intelligent meter users, the concentrator establishes a main network, collects the data of the use levels of the intelligent meter users and transmits the reading management command, the master station server generates and sends the reading management command, receives the data of the use levels of the intelligent meter users and analyzes and manages the data. The subnet relay provided by the invention can relay and transmits the data of the use levels of the intelligent meter users, sent by the intelligent meter, when the number of the intelligent meters is great, so that the problem that in the subnet, the volume of the data of the use levels of the intelligent meter users, sent by the intelligent meter farther from the collector, is easy to lose is effectively solved. The system has the advantage of strong reliability.
Description
technical field [0001] The invention relates to a meter reading system, in particular to a wireless smart meter reading system. Background technique [0002] With the improvement of people's living standards, people's requirements for the living environment have also put forward higher requirements, and various electrical instruments have also entered thousands of households, providing convenience for people's lives. Intelligent home and community intelligence are not only available in individual high-end communities. With the continuous development of technology and the strong support of the government, more and more communities have installed automatic communication systems of various communication methods. Meter reading system. After more than ten years of development, the overall quality of IC card smart gas meters has also improved to a level that basically meets the practical application, and has solved the long-term problems of "difficulty in meter reading" and "diff...
