Abstract
In order to increase the management efficiency and decrease the maintenance costs in the traditional dust monitoring system, a novel real-time remote monitoring system using the Internet of Things and cloud server is proposed in this paper. The system includes several sensor nodes, a sink node and Cloud Server. The high-precision dust probe, temperature and humidity sensors, water flow sensors and hydrogen transmitters are integrated together into a sensor node to access the metal polished environmental information. Then, the collected information is transmitted to sink-node using the 2.4G wireless network. The sink-node uploads data to the Cloud Server through the 4G network and TCP Socket. Based on the Browser/Server (B/S) model, a remote monitoring system is developed by using Tencent Cloud Server, C# language, and SQL database. As a result, the on-site metal polishing environmental information is obtained via the App and Web page.
Highlights
In recent years, the dust explosion in industrial processes has caused a lot of property losses and casualties
The manufacturing process cannot be effectively supervised during the metal polishing, and the common monitoring methods require a number of manpower and material resources [2]
The sink node is the brain of Data Collection Layer, which uploads the received data to the Cloud Server through 4G network, updates the information on the HMI interface in time, and determines whether the data exceeds the alert threshold
Summary
The dust explosion in industrial processes has caused a lot of property losses and casualties. It is serious in the metal polishing industry. How to acquire polished site data timely and provide accurate warning measurement has become a very urgent issue [1]. The Internet of Things is a new information technology which is highly integrated with sensors, the Internet, and data processing technologies. It has been developed rapidly in recent years [3]. The aggregated and processed data is uploaded to the Cloud Server via the 4G network. APP and Web page view the metal polished environmental information conveniently and timely [4]
