中国应用现状(Application status in China)
The degree of automation of industrial enterprises in China is generally low, PLC products have great application space, such as more than 80% of the mechanical equipment industry is still using the traditional relay and contactor control. Therefore, the application of PLC in our country is far from potential into full play.
Chinas large and medium-sized enterprises generally adopt the advanced automation system to control the production process, but has not been used in most automation system of small and medium-sized enterprises and products to control the production process. With the increasing competition, more and more small businesses will adopt economic and practical automation products to control the production process, to improve the economic efficiency of enterprises and competitiveness.
More and more international companies Chinese after joining WTO to move its manufacturing base to Chinese. At the same time, Chinese state-owned enterprises and private enterprises are taking advantage of a rare historical opportunity to develop the manufacturing industry. China is trying to become the new manufacturing base in the world. Control mainly discrete manufacturing control, the control system of PLC is preferred. Manufacturing enterprises to improve labor productivity and product quality, will use a large number of PLC, which provides broad prospects for the application of PLC.
Since 2001, as one of the basic industries of machinery industry has become a new growth point of Chinas industrial development, the average annual growth rate of over 20%. With the industrial process of analog feedback regulation of different mechanical industry need for chain and sequence control of switch, PLC control products as their preferred. The rapid growth of mechanical industry and the automation status provides a huge market space for the PLC application.
The development plan of China in the fifteen plan has been clearly put forward use info
