industrial automation control technology is the application of control theory, instrumentation, computer and information technology, industrial production processes for detection, control, optimization, scheduling, management and decision-making, increase yield and improve quality, reduce consumption, to ensure the safety of integrated technology. at present, the industry is mainly involved in electric power, electronics, computers, artificial intelligence, communications and electrical machinery and other fields.

with the rapid development of traditional industrial technology, factory automation and enterprise information, the demand of industrial automation system will increase. last year, china's industrial automatic control system market size reached 380 billion yuan. because of the industrial automation control system device for a wide range of products, market demand, competition is intense, domestic enterprises in the high-end products are the key technology r & d and manufacturing of products, there is still a large gap compared to foreign countries. in recent years, the domestic enterprises to the introduction of foreign production technology and independent research and development, and constantly narrowing the gap with foreign enterprises. at the same time, the domestic integrated enterprises in the localization of production, product prices and sales channels also have certain advantages.

from the industrial chain, industrial automatic control system for electrical components, mainly upstream and downstream steel machinery parts; mainly related to the chemical industry, electric power, robots, electric vehicles, rail transportation and other fields. among them, the downstream robot, rail transportation market demand is increasing year by year, will have a great impetus for the rapid development of industrial automation industry, is expected to become an important direction of the industrial automation control of the diversified development of enterprises.

rail traction system, signal control system, converter, motor and high voltage box are typical industrial control driver and power supply equipment. with the rapid growth of china's urban rail transit construction, industrial automation control system will also usher in rapid development opportunities. as of last year, china's rail transportation plan approved 44 city, 26 city has been opening and operation of city rail transportation, a total of 116 lines, a total length of 3618 km line operators. among them, the subway 2658 kilometers, accounting for 73.4%. in addition, last year china's new city rail transit line mileage of 445 kilometers, an increase of 14% over the previous year, is expected to 2020, china will have 50 city owned city rail transportation, the total operating mileage is expected to reach 6000 kilometers.

in addition, as china's labor costs and increase support policies continue to overweight, the rapid popularization of industrial robots will drive automation control equipment demand. data show that last year china's demand for industrial robots to 66 thousand units, to 2020, the robot will reach 200 thousand units, servo motor and drive robot market demand will exceed 4 billion 500 million yuan, at the same time servo system integration business will reach 13 billion yuan. robot industry development plan (2016-2020) proposed that by 2020 china's annual output of industrial robots will reach 100 thousand units. among them, the six axis and above the robot reached more than 50 thousand, the robot density of more than 150 units.
