LoRa-based concrete temperature measurement system

Abstract

The invention relates to a LoRa-based concrete temperature measurement system which comprises a data acquisition module, a data transmission gateway and a data monitoring center; the data acquisitionmodule comprises an acquisition terminal and one or more temperature sensors, wherein the acquisition terminal comprises an MCU, a sensor port, a storage unit and a power supply module; an SoC modulewith a LoRa function is adopted as the MCU; the sensor port is connected with one or more concrete embedded wires; the data transmission gateway comprises a processor core, a LoRa gateway module, a display module, an input module, a point-to-point port, a public network interface, a storage unit and a power supply module; the LoRa gateway module is connected with the MUC of the data acquisition terminal; the data acquisition module communicates with the data transmission gateway through LoRa; and the data transmission gateway sends data to the data monitoring center. The system can realize large-range, multi-measuring-point, long-distance and different-place detection of concrete temperature measurement data; and the detection of the system has real-time performance, accuracy, effectiveness, stability and flexibility.

Description

technical field [0001] The invention belongs to the field of building construction monitoring, in particular to a concrete temperature measurement system based on LoRa. Background technique [0002] Nowadays, when traditional technology is used for concrete temperature measurement and detection, the transmission of detected temperature data mostly adopts wired mode, and some adopt GPRS mode. There are following deficiencies in the above-mentioned way: [0003] 1. The wired method needs to lay out a communication network, generally in the form of embedded wires. This will bring the problem of high wire cost and inconvenient deployment during the construction process. The conditions on the construction site are complex, and cable disconnection may occur, which will greatly affect the stability of the detection. Moreover, if the line is too long, the signal will be attenuated, so the wired transmission generally needs to arrange a detection room on site, which will increase ...

AI Technical Summary

Problems solved by technology

This will bring the problem of high wire cost and the construction process is inconvenient to deploy

The conditions on the construction site are complicated, and there will be situations such as cable breakage, which will greatly affect the stability of the detection

Moreover, if the line is too long, the signal will be attenuated, so wired transmission generally needs to arrange a detection room on site, which will increase the workload

[0004] 2. The applicability of the GPRS method is not strong, the network speed is low, and the cost and power consumption are high, so it cannot be applied to each terminal. The general method is to collect data through wired methods first, and then perform GPRS at a single point. Forward

This method is not very good to save wire
