LoRa-based low voltage user data transmission method

Abstract

The invention discloses a LoRa-based low voltage user data transmission method. The method comprises the following steps of a, centralizing and calculating low voltage users; b, selecting an address nearby a scope node, constructing a communication machine room, and guaranteed that intelligent meter data is communicated with the communication machine room; c, constructing a distribution network ina centralizing manner, performing unified security management on power of low voltage users of each range node, constructing a distribution network, and storing and transmitting data in real time; d,verifying data of the intelligent meter primarily; and e, uniformly analyzing transmitted data by a background general data end, tabulating, and then storing uniformly. A remote meter reading systemis realized based on a LoRa technology, and the method has the advantages of wide coverage, low communication cost, and efficient, real-time remote data reading, enables a power enterprise to manage meter reading business more regularly, and solves a problem that nodes are distributed and are hard to manage, thereby being an ideal power data transmission solution of the power related enterprises.

Description

technical field [0001] The invention relates to the technical field of intelligent data transmission, in particular to a LoRa-based low-voltage user data transmission method. Background technique [0002] Data transmission is the communication process in which data is sent from one place to another. A data transmission system usually consists of a transmission channel and data circuit terminating equipment (DCE) at both ends of the channel, and in some cases, multiplexing equipment at both ends of the channel. The transmission channel can be a dedicated communication channel, or it can be provided by a data switching network, a telephone switching network or other types of switching networks. The input and output devices of the data transmission system are terminals or computers, collectively referred to as data terminal equipment (DTE). The data information sent by it is generally a combination of letters, numbers and symbols. In order to transmit these information, each l...

Problems solved by technology

With the development of industrial automation, remote meter reading has become an important part of the smart grid. The traditional manual power meter reading method has disadvantages such as large number, wide distribution, and large errors. Moreover, some meters are installed in remote locations, and some need to be charged. The operation is relatively dangerous and requires a lot of manpower and material resources. In addition to causing a serious waste of resources, there are many deficiencies in real-time, accuracy and applicability. For the above, how to invent a Based on the LoRa low-voltage user data transmission method, this becomes a problem we need to solve
