Multichannel Temperature Acquisition and Monitoring System Based on Internet of Things

Abstract

In order to reduce the damage of mine submersible pump (MSP) caused by temperature fault, this paper proposes a way that a multiplexer and temperature sensor as the acquisition means, and the single-chip microcomputer (MCU) is used as the main controller, with RS485 communication module and ZigBee wireless RF module as the transmission signal means, PC and cloud server as a real-time monitoring method, which can effectively collect and monitor the real-time change of temperature parameters in the production process of MSP in wireless environment. Therefore, a solution based on the Internet of Things (IoT) multi-channel temperature acquisition and monitoring system is designed. The framework, hardware and cloud server of the whole system is designed, and the sensing data is transmitted wireless to the cloud server through ZigBee technology. Cloud server performs real-time analysis and processing of the collected signal, and controls the change of temperature terminal according to the cloud feedback. Compared with the traditional method, the system has strong expansibility, stable operation, complete functions and low cost, which can be widely used in various temperature acquisition and monitoring projects with low degree of automation.
