I. Overview:
Smart factory is a new stage of modern factory informatization development. It uses Internet of Things technology and equipment monitoring technology on the basis of digital factory to strengthen information management and services; to achieve a clear grasp of the production and sales process and improve the controllability of the production process It can reduce the manual intervention of the production line, achieve real-time and correct collection of production line data, and reasonable control of the production plan and production schedule. Coupled with the adoption of emerging technologies such as green intelligent systems, a high-efficiency, energy-saving, environmentally friendly, and environmentally comfortable humanized chemical plant will be constructed.
At present, many equipment in the factory operate independently and are not connected, and the inability of equipment operating status and production cycle data to flow leads to the formation of information islands, and it is impossible to systematically analyze and optimize the data. Use IoT technology to realize the interconnection and smart management of personnel (authority management), machines (monitoring equipment), things (data collection), and production environment (monitoring and energy consumption); combine IoT technology in the construction of smart factories , Which can effectively reduce production costs, save energy and reduce consumption, and optimize the process flow is an inevitable choice from manufacturing to intelligent manufacturing.
Two main features:
1. Device interconnection. It can realize equipment-to-equipment interconnection (M2M). Through integration with equipment control system and external sensors, SCADA (data acquisition and monitoring system) collects equipment status in real time, production completed information and quality information, and through the application of RFID (Radio frequency technology), barcode (one-dimensional and two-dimensional) and other technologies to realize the traceability of the production process.
