Development Of Industrial Robot Remote Monitoring Diagnostic Services System

With the rapid development of China’s economy and industrial upgrading, modern industrial robots are used more and more widely in flexible manufacturing. Stable and reliable robotic arms on the production guarantee stability and economic significance. High technical staff requirements are needed because of industrial robots’ complicated mechanism and high maintenance costs. The status means industrial robots manufacturers have to provide products with high-quality service. To solve this problem, we cooperate with Shenyang SinSun Robots to develop a complete set of remote monitoring platform system with diagnostic service based on SinSun’s industrial robots. This article studies the design principles of this platform, and proposes the complete design.This paper describes and analyzes the remote service systems of ABB industrial robots and Fanuc robots. On the basis of analysis of these two systems’ advantages and disadvantages, we propose the design of a more sophisticated remote monitoring diagnostics service platform system.This paper presents a solution for the remote platform system based on three-tier structure: live "perception layer", message "transport layer" and the remote data center. The main design work includes the following aspects:Firstly, we propose the design the core components of whole system--live "perception layer" data acquisition controller. The data acquisition controller is an embedded system, with a variety of communication interfaces including DTU, wired Ethernet, RS485, Zigbee, etc. The data acquisition controller can be connected with the industrial robot control cabinet directly, and read the real-time operating data and status of the robot. It can also monitor the alarming and warning data, sending the data to local data server and remote service center at the first time. Remote commanding and debugging from the remote server center is also supported in this system.For a more comprehensive monitoring the robots’running status, the paper proposed and designed auxiliary measurement sensors to measure the ambient temperature, humidity, tilt, vibration, and some other parameters. Auxiliary sensors connect data acquisition controller through Zigbee wireless transmission module. It’s easy to use and extend. Secondly, the paper proposes designs of local monitoring software in conjunction with remote monitoring system at the same time, which is based on C/S mode. The local monitoring software contains local monitoring and commissioning functions. It can cooperate with the remote platform to help build the interaction between remote engineers with local staff. It’s easier for them to solve the robots’problems.Finally, the paper elaborates the design of remote monitoring diagnostic system software. The software is based on B/S Web data publishing software, including the communication configuration module, data acquisition module, robot control module, fault diagnosis module, forecasting and warning module, remote auxiliary processing module and so on.The designs we proposed in this paper is based on the SinSun SR6C industrial robot, we’ll try to support some other models of robots in this system.
