ABB 086348-001 线性控制 全系列进口备件

In 1983, the industrial control computer was included in the national computer series spectrum and development plan. At present, our industrial control computer (including industrial control computer system, dispersed industrial control computer system, industrial control function module series, automatic testing system and numerical control, program control device five series) technology, industry and application have developed greatly, the Chinese industrial control machine industry has been formed.

The development of industrial control system in our country, most of which is introduced in complete sets of equipment, also introduces various industrial control system in the future, and begins to design its own control system and device, which is then digested and absorbed, and secondary development and application. Some also introduce technology and foreign joint venture to assemble and produce foreign products and gradually realize localization. At present, China's industrial computer market scale is 9.5 ~ 12.7 billion yuan, including industrial PC and board card 2.5 ~ 3 billion yuan; Embedded computer (including controller) 1.5 ~ 2 billion yuan; PLC scale is 1.5 ~ 1.7 billion yuan; DCS system 1.5 ~ 2 billion yuan; Numerical control system 1.5 ~ 2 billion yuan; About 2 billion yuan was imported for supporting control equipment for mechanical and electrical equipment. In this survey, the manufacturer of PLC accounted for 30.43%; Industrial PC production accounted for 21.74%; DCS production accounted for 17.39%; FCS accounted for 8.7%; Other (automatic instrument, module) is 21.74%. At present, our PLC production has a certain development, some varieties of small PLC has been produced in batches, medium-sized PLC already products, large PLC has begun to develop, some products not only supply the domestic market, but also export. PLC is mainly used in all kinds of furnaces, machine tools, machinery, metallurgy, all kinds of production lines, railways, water treatment equipment and so on.

About 30 domestic PLC production enterprises, annual output of more than 1000 sets less than 10. The main production units are: Suzhou Machine Tool Electrical Factory, Shanghai Xiangdao Electromechanical Manufacturing Co., LTD., Beijing Machinery Industry Automation Institute of the Ministry of Machinery, Jiangsu Jiahua Industry Co., LTD., Suzhou Electronic Computer Factory, Hangzhou Machine Tool Electrical Factory, Liaoning Radio 2 Factory, etc. The market share of domestic products shall not exceed 10%. In 1996, about 90,000 sets were sold, including 80,000 imported sets (with foreign exchange of 120 million US dollars), totaling about 1.5 billion yuan.

In this survey, customers using Siemens products accounted for 20.83%, while Modicon, A-B and OMRON users accounted for 14.58% respectively. Mitsubishi accounts for 8.33%; GE accounted for 6.25%; Fujifilm accounted for 4.17%; Others (Hitachi, Mitsuyang, Toshiba, NEC, Samsung, B&R, Lima (Beijing Machinery Industry Automation Institute Electronics Factory) and Ka Wah each accounted for 2.08 percent. According to the results of the sample survey, the majority of PLC products selected by customers are still foreign products, and most of them are SIEMENS, MODICON, A-B, OMRON, GE and Mitsubishi.
