With the rapid development of science and technology, various equipment manufacturers have emerged, and equipment manufacturers have become an important part of the development of productivity. How to improve the management level and improve the efficiency and competitiveness of enterprises is an increasingly severe problem from management to the grassroots. How to improve the efficiency of equipment operation and maintenance and do a good job in after-sales management and control is indeed a major focus area for manufacturers of industrial equipment automation testing and control equipment to improve their performance, and the establishment of an intelligent all-round remote equipment monitoring and management system is a model for this industry. Change is technological innovation + management innovation.
2. Design plan2.1 System introduction
The equipment remote monitoring system plays an important role in the construction of enterprise business implementation layer management information. It is a comprehensive information system with the core of providing multi-departmental and all-round equipment remote monitoring and management. It also provides information on higher-level enterprise management systems. Effective interface.
The following figure shows the relationship between this system and other information systems:
The above figure shows the information span of the system. The system is based on the three-level operation management layer, while supplementing and improving the equipment remote monitoring and management functions, and providing real-time/historical equipment analysis data and after-sales analysis data for production management MES and enterprise ERP. At the same time, its expert analysis data will also support the enterprise's business intelligence and business decision-making needs.
Device remote monitoring system architecture diagram
In the above figure, the hardware and software of the data acquisition system are used to collect real-time status, parameters, faults and other data of equipment including PLCs, meters or industrial computers, etc., through the VPN method, the data acquisition system transmits the data to the cloud communication service remotely. The cloud communication service receives and processes the data and stores it in the data server, and then processes the data through the application server and provides it to the WEB end (PC, tablet, mobile phone) or APP end for display, analysis, diagnosis and management through web or webservice. Waiting for the interface.
2.2 System function introduction
Equipment data collection
Data collection on monitored objects (ie products sold by the company to customers). The content of data collection includes product operating signals, operating data, output information, system parameters, fault signals, trend signals, and key video signals processed by industrial computer control software. At the same time, if allowed by the user site, it can be Modify product parameters remotely.
Equipment fault management
Real-time alarm for on-site faults; real-time viewing and historical query of product faults; able to generate early warnings by setting the upper and lower limits of the analog quantity, and the rate of change (if necessary, basic calculations in the PLC can be required), and can be time-sharing , Perform statistics by product, and export alarm reports. The alarm information should include product customers, product attributes, alarm generation time, alarm elimination time, alarm confirmation time, alarm confirmation person, etc.
Remote diagnosis of equipment
Through fault information, picture information and early warning information, the status and operating value of related variables can be traced back when the fault occurs, and combined with the operating curve graph, it can help monitors to perform remote fault diagnosis and analysis.
Device parameter modification
After the on-site user sends a request instruction (such as pressing the request assistance button on the on-site operation interface) or the super user logs in, the remote parameters can be modified.
