As the easiest and fastest method for preparing nanofibers, electrospinning has the characteristics of high porosity and large specific surface area, so it has been widely used in the production fields of wastewater filtration materials, medical protective materials, sensors and so on. The principle is that in a high-voltage electrostatic environment, the polymer solution or solution is stretched, evaporated, solidified, etc., and finally deposited on the receiving device to form a nanofiber membrane. Among them, the control operation of the PLC is crucial.
In the process of electrospinning, voltage, current, temperature and humidity and other data have an important impact on product quality, and whether abnormal data can be monitored in real time and managed and controlled in time has become one of the standards for detection results. By connecting the PLC in the electrospinning machine to the industrial intelligent gateway of Wutong Bolian for real-time data collection and communication, it can alarm the fault and realize remote maintenance, help maintain a safe and stable production order, and reduce material waste and other losses.
Solution. The electrospinning machine PLC is connected to the industrial intelligent gateway through the serial port network port, and the gateway automatically parses the protocol and conducts all-weather data collection, collects important parameters such as voltage, current, temperature and humidity and uploads them to the industrial Internet of Things platform in real time, so as to realize data visualization monitoring, fault alarm, equipment management, remote maintenance and data analysis, and take timely measures to manage and control to avoid major accidents and economic losses.
System features. 1. Data collection: The gateway has diversified PLC protocol analysis and data collection capabilities, and supports docking to the cloud platform or host computer through 5G 4G WiFi Ethernet, etc., and establishes a real-time communication network to achieve local monitoring and remote monitoring.
2. Edge computing: support various edge computing functions such as intelligent collection, data filtering, alarm calculation, jump trigger, formula calculation, grouping strategy, etc., which greatly saves the R&D and construction costs of the project after eliminating equipment heterogeneity and achieving standardization.
3. Fault alarm: The user can quickly configure alarm rules and notification methods, quickly alarm when abnormal fault data is detected, support WeChat, SMS, email and other notification methods, inform the alarm information and generate operation and maintenance work orders.
4. Remote O&M: The gateway and the equipment O&M Express can quickly build a data channel to the remote equipment site, and realize the functions of remote configuration, remote debugging, remote diagnosis, and remote update program for on-site equipment.
5. Equipment management: realize the editing and management of equipment information across the country, remotely view the equipment location distribution, quantity type, working parameters, alarm events and other information, and realize flexible and efficient resource scheduling and allocation.
6. Data analysis: Through a variety of visual data charts, evaluate and analyze the equipment failure level, maintenance efficiency, work performance, etc., so as to make scientific and reasonable decisions and realize intelligent management upgrades.
