[Abstract]:Remote monitoring refers to the technology of monitoring and controlling remote production equipment by means of computer network, communication and control. In the field of industrial control, the remote monitoring system can be used to realize the real-time data viewing and equipment operation control of the local equipment, so as to improve the efficiency of equipment management and reduce the production cost. The remote monitoring and control system of continuous casting equipment can improve the ability of feedback information on the operation state of continuous casting equipment and strengthen the operation mechanism of effective control of continuous casting equipment. It is of great significance to realize the optimization of equipment research and development and realize the sharing of data resources in a wide range. In this paper, a remote control system for the running state of continuous casting equipment is developed and designed on the basis of the sub-research of the cooperative project between our school and Shanghai Yaxin continuous casting Technology Engineering Co., Ltd. To realize the remote monitoring of the subsidiary R8m 7 machine and seven flow arc billet continuous casting equipment by the company's headquarter. Based on the analysis and summary of the status quo, technical requirements and the company's actual conditions of the remote monitoring system for continuous casting equipment, this paper, through the analysis and comparison of eight sets of schemes, adopts the GRM20G-C model intelligent controller. The remote monitoring scheme of continuous casting equipment is designed for PLC data acquisition directly. Through the connection between the intelligent controller and the eight S7-300 PLC of continuous casting equipment through RS485 serial port, the local data is collected and the remote wireless transmission is realized with the help of 4G GPRS network, which breaks through the limitation that the local industrial control computer has no network connection. With the help of Web pages and WINCC software, the remote terminal can realize the remote monitoring of the R8m 7 machine and seven flow arc billet continuous casting equipment. The monitoring system is advanced in technology, flexible in monitoring mode, simple and easy to operate, and has obvious advantages over the traditional B / S and C / S monitoring architecture. By using WinCC software to monitor traffic light equipment under the condition of campus network and company network respectively, it can be seen that under campus network, the system start / stop response time fluctuates in the 0.13s-0.19s range: under the company network, the system starts / stops response time fluctuates in the range of 0.13s-0.19s: under the company network, The start / stop response time of the system fluctuates in the range of 0.23 ~ 0.29, which meets the requirement of 0.5 s system response time. In addition, the system data monitoring accuracy can reach 100, meet the system remote monitoring equipment accuracy requirements. This system has good performance such as real time, accuracy and security. It can be used for reference to monitor the R8m 7 machine and 7 flow billet continuous casting equipment or other models of continuous casting equipment, and to improve the performance of remote monitoring system.
