Embodiment 1

[0046] Such as figure 1 As shown, this embodiment provides a meter reading system based on the JRoute micro-power wireless ad hoc network, including: a smart meter, a concentrator, and a master station.

[0047] Among them, multiple smart meters are connected to the concentrator controlling multiple smart meters through the JRoute micro-power wireless ad hoc network; multiple concentrators are connected to the master station controlling multiple concentrators through GPRS, private network or optical fiber.

[0048]It should be noted that the JRoute micro-power wireless ad hoc network is a micro-power wireless communication method independently developed by the present invention. The communication method includes a network search algorithm, an ad hoc network algorithm, and a signal transmission method, wherein the signal transmission method particularly adopts a narrowband communication method. The data transmission between the smart meter and the concentrator and between the ...

Embodiment 2

[0067] This embodiment provides a method for centralized meter reading based on the JRoute micro-power wireless ad hoc network, including: a smart meter, a concentrator, and a master station. The concentrator and the main station are connected through GPRS, private network or optical fiber. Between the smart meter and the concentrator and between the smart meters, the optimal routing method in the JRoute micro-power wireless ad hoc network and the optimized depth-first search method are used to search for the target node. The following is a detailed description of the optimal routing method and the optimized depth-first search method:

[0068] 1. Optimized depth-first search method

[0069] The basic depth-first search is characterized by image 3 As shown, when networking, search along the vertical direction, and use "loop detection", "regression", and "detour" to prevent an infinite loop and quickly find the target node. Solve the communication problem first, and then opt...

Embodiment 3

[0103] This embodiment provides a method for centralized reading of electric meters based on the JRoute micro-power wireless ad hoc network and using the cable television broadcast frequency band for data transmission.

[0104] GYT106-1999 "Technical Specifications for Cable TV Broadcasting System" standard stipulates that the frequency range of cable TV is 5-1000MHz, of which 5-65MHz is the uplink frequency band, and 87-1000MHz is the downlink frequency band. At present, the actual downlink frequency in various places is 87-750MHz, more often it is 47-550MHz, and the bandwidth of each channel is 8MHz. Its frequency band includes the frequency band specified by the micro-power wireless ad hoc network of the State Grid electricity information collection system, and because its bandwidth is 8MHz, if interference occurs, it will interfere with each other, causing the micro-power wireless ad hoc network to fail to communicate normally. There is a gap in the TV broadcast signal.

Abstract

The present invention provides a system and method for centralized reading of electric meters based on JRoute micro-power wireless ad hoc network. ; At least one of the concentrators is connected to a master station that controls the at least one concentrator; wherein, the data transmission bandwidth between the smart meter and the concentrator and between smart meters is a preset bandwidth value. Compared with the prior art, the present invention utilizes narrowband for data transmission, which reduces the interference between channels. At the same time, the communication retry time is reduced, the network communication success rate is increased, and the communication efficiency is improved. In addition, the present invention adopts the optimal routing method in the JRoute micro-power wireless ad hoc network and the optimal depth-first search method to calculate and select the optimal path to ensure smooth network and improve communication efficiency.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a system and method for centralized reading of electric meters based on JRoute micropower wireless ad hoc network. Background technique [0002] Micropower wireless is a low-cost, low-power, small-volume wireless communication method suitable for short-distance information transmission. The ad hoc network is a communication method that allows a group of devices with the same sending and receiving types to form a network, and each device can communicate with each other, and supports forwarding, so that two devices that cannot communicate directly can Data communication by means of forwarding from other devices. Micro-power wireless ad hoc network is currently the most widely used communication method in a short-distance, multi-node (device) communication environment. Its advantages are: a communication network can be quickly built at any time and any place, and an...
