Design And Development Of Remote Monitoring System Based On Io T For Grind Stone Machine

With the rapid development of manufacturing industry, the development mode of manufacturing industry will shift from the extensive mode into the meticulous, scientific mode, especially with the execution of strategies, such as “made in China 2025” and “Internet +”, proposed by the 13 th Five Year Plan. Now, many manufacturing enterprises emphasize on the intelligent, green and quality in the process of production. The traditional method, which monitors the device running status by mechanical instrument and regularly patrols by manual, can't satisfy the requirements of industry development. The large-sized industrial device is expensive and plays a key role in the process of enterprise production. Monitoring its real-time operation status can protect the device, prolong its life time, improve the production efficiency and enhance the product quality.This paper adopts the embedded technology, wireless communication technology and cloud server technology to design and develop a remote monitoring system based on IoT for grind stone machine. The operation video, revolving speed, lubricating oil level and power consumption of the grind stone machine are obtained real-timely. It realizes intelligent management, improves business production efficiency and enhances product quality for the grinding quarry through detecting the above parameters.The main contributions of this paper are as follows:(1) Requirement analyses and system function design: considering the running management requirement for the grinding stone machine and the current state of the art industry device monitoring system, this paper proposes the detecting demand with the manufacturing enterprise corporately, then we investigates relational technologies and designs system function on the basis of product requirement.(2) System scheme design: the system is based on the IoT architecture and includes two sub-systems. One is the grinding video monitoring sub-system and the other is running status monitoring sub-system for the grinding stone machine. These two systems work collaboratively and present the running status of the grinding stone machine to the administrator visually and digitally.(3) System implementation: the video monitoring sub-system adopts Hi3515 H.264 as the main control chip. The video information is collected by the camera and pushed to the cloud management platform using Real Time Messaging Protocol with 4G or WiFi. The operation status monitoring sub-system adopts STM32F103ZET6, produced by STMicroelectronics, to gather the revolving speed, lubricating oil level and power consumption of the grind stone machine. Then, the above information is transmitted to the cloud management platform by GPRS or WiFi, to achieve remote real-time monitoring for the grind stone machine.(4) The overall system function test: this paper adopts embedded front end and cloud management platform to fulfill the spot test collaboratively. The test results show that the video monitoring sub-system can push the video to the cloud management platform successfully and the video quality is clear and fluent. The operation status monitoring sub-system can transmit the revolving speed, lubricating oil level and power consumption of the grind stone machine to the cloud management platform. The user can log in the cloud management platform to view the real-time power consumption graph, revolving speed information. Also, while the oil level is lower than the threshold, the platform triggers the alarm.(5) This paper concludes the research results and analyze how to optimize the system.
