Intelligent meter reading system based on LoRa wireless network

Abstract

The invention relates to an intelligent meter reading system based on a LoRa wireless network. The intelligent meter reading system comprises a background server, a mobile phone terminal, a LoRa gateway and a collecting terminal, wherein the collecting terminal is connected with a plurality of meters; the LoRa gateway comprises an embedded microprocessor, a first LoRa communication module, a network communication module and an RS485 serial port; the collecting terminal comprises a microcontroller, a second LoRa communication module, a first storage module, a first display module, a first RF communication module, a fingerprint recognition module, a first block module, a first power supply module and a first electric quantity monitoring module; each meter comprises a MCU, a flow sensor, a second storage module, a second display module, a second RF communication module, an operation push button, a second block module, a second power supply module and a second electric quantity monitoringmodule; the second electric quantity monitoring module is connected with the second power supply module through a signal wire. The intelligent meter reading system has the advantages that the transmission distance is long; the use is convenient; intelligentialization and automation are realized.

Description

technical field [0001] The invention belongs to the technical field of safety monitoring, and in particular relates to an intelligent meter reading system based on a LoRa wireless network. Background technique [0002] Gas and tap water are indispensable resources in people's daily life, and they are also the most consumed resources in people's daily life. Both gas and tap water require the corresponding management department to read the meter regularly to obtain the user's gas or water consumption. And according to the corresponding charging standard, calculate the fee that the user needs to pay, and then collect the corresponding fee from the user. [0003] At present, the meter reading mode adopted in most areas is that the management personnel of the corresponding management department regularly go to the user's home to read the metering data in the meter, and then record the read metering data into the paper record book through the mobile app or manually , and then go ...

Problems solved by technology

[0003] At present, the meter reading mode adopted in most areas is that the management personnel of the corresponding management department regularly go to the user's home to read the metering data in the meter, and then record the read metering data into the paper record book through the mobile app or manually , and then go back to the acquired management center to input it into the computer for cost calculation. This method of meter reading will undoubtedly increase the workload of the meter reader. At the same time, the monitoring data collection of the meter relies too much on human factors. Accurate or inaccurate data entered into the computer of the management center will lead to errors in the fee information that users need to pay, which will bring serious inconvenience to fee management
