Building operation data acquisition system and method based on LoRa communication technology of Internet of things

Abstract

The invention discloses a building operation data acquisition system and method based on the LoRa communication technology of the Internet of things, and relates to the technical field of the Internetof things. An external sensor is used for measuring the parameters of a measured object, converting the parameters into digital or mode quantity and sending the digital or mode quantity to a LoRa node acquisition device. The LoRa node acquisition device converts data to LoRa data and then sends the LoRa data to a dual-channel LoRa gateway. The gateway accepts a registration request of the LoRa node acquisition device and stores the LoRa format data on a memory, and the data is converted into Internet format data and then uploaded to a cloud server. The cloud server is used for forming variousmeasured parameter values through analysis according to a communication protocol, and the parameter values are stored and analyzed through a cloud intelligent analysis software. The intelligent terminal device reads the data of the cloud server and displays the collected data according to the requirement of a user. The system is simple and flexible in installation, the cost is low, the cycle is short, the implementation difficulty is low, the accuracy and the efficiency are improved, and normal use of existing constructed buildings is ensured.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a building operation data acquisition system and method based on the LoRa communication technology of the Internet of Things. Background technique [0002] With the improvement of social awareness of energy conservation and the demand for building digital management, it is necessary to collect and upload real-time operation data to the server for new buildings and buildings that have already been in operation. Room temperature and humidity, carbon dioxide concentration, PM2.5 concentration energy and real-time operating parameters and energy consumption of various systems serving the building, such as HVAC heating, ventilation and air conditioning systems, building lighting systems, etc., and the collected real-time data as energy-saving Control and environmental control basis to realize the energy-saving operation of buildings and the safety and health of ...

AI Technical Summary

Problems solved by technology

[0003] Existing building data acquisition systems are all based on wired data transmission, which requires a lot of wiring work from the sensor to the upper-level collector, and the sensor must be installed inside the equipment or inside the system pipeline, the installation cost is high, the cycle is long, and the maintenance cost is also high; Especially for buildings that have been put into operation, it is necessary to shut down the installation, and when collecting parameters such as flow, pressure, and temperature of the HVAC HVAC system, all the water in the system must be drained, resulting in a large waste of resources and manpower, and affecting The normal operation of buildings cannot be implemented in some 24-hour buildings such as hotels and hospitals; in addition, even if a lot of money and time are spent on local data collection, the data can only be displayed at a fixed location On the host computer in the control room, the Internet+ and mobile interconnection of data cannot be realized

[0004] In order to solve the problems of high cost, long cycle, difficult implementation, and affecting the normal use of buildings in operation in traditional data acquisition systems, it is especially important to design a real-time acquisition system and method for building operating data based on the LoRa communication technology of the Internet of Things. necessary
