In industrial automation production lines such as automobile manufacturing and electronic equipment production, DSQC346B can collect real-time operation status signals of various equipment on the production line, such as equipment start stop, position detection, etc., and accurately control the operation of the equipment according to preset programs, realizing a series of automated operations such as material handling, processing, assembly, etc., effectively improving production efficiency and product quality, and reducing labor costs.
2. Process control field
In the process control industries such as chemical, power, and metallurgy, this system can accurately collect and control key process parameters such as temperature, pressure, and flow rate. For example, in chemical production, real-time monitoring and adjustment of temperature and pressure inside the reaction vessel ensure that the chemical reaction proceeds under optimal conditions, improve product yield and quality, and ensure the safe and stable operation of the production process.
3. Intelligent warehousing and logistics
In the intelligent warehousing and logistics system, DSQC346B can collaborate with automated three-dimensional warehouses, stackers, conveyors, and other equipment. By collecting information such as the location of goods and the operating status of equipment, automatic storage, retrieval, and handling of goods can be achieved, improving the operational efficiency of warehousing and logistics, and reducing errors during the storage and transportation of goods.
