To Meiteng, the core goals and needs for intelligent CHPP is less worker, even unmanned. By adding sensors, software, human interface device, part of the production links can now work perfectly with unmanned guarding and manual patrolling. Compared to manual experiences, production parameters adjustment can be much more accurate with computer model calculation; automatic filling and analysis of production data can be much more efficient than that of paper recording and hand writing; and the equipment fault diagnosis detected by sensors is much more timely than manual checking. In order to achieve the goal of human-free plant, Meiteng has developed unmanned products and solutions targeting each CHPP process link.
