Festo (china) Co., Ltd. Wang Xiongyao Interview
Power transmission equipment, whether it is Hydraulic pressure , And pneumatic or mechanical, it is movement and control of vector or the executors, they constitute a point in the motion control system. In fact the broad movement control should include numerous interrelated that point, these points are composed of line is what we call the production line. Only when this “lifeline” has good movement and control capabilities, it can reach the ideal state of productivity.
MM: First of all, you talk about in the industrial areas which primarily contains the movement and control, and your production process understanding and control of movement.
Mr. Wang Xiongyao: When it comes to industrial areas, “Movement and Control” the subject, I will be reminded of a famous Festo Advertisement Words: “First in Motion”, refers to the Automation Sports fields, Festo is the first. I think that the “first” term is to express this more Festo pneumatic technology from the beginning recognized the control and movement are inseparable from the idea. If the technology from the air (including pneumatic) attributed to “control and movement,” the concept of point of view, the entire pneumatic control technology is the air flow source, the signal input, signal processing, and command (movement execution) of four parts.
Pneumatic technology has a remarkable feature: the integration of technology from the control point of view, it has been with the computer, electronics, communications, sensing, and machine control technology closely related together; from the movement of functional integration to see more and more of these products. Such as: an As-i bus interface with a valve cylinder, which consists of a cylinder (sport), a 2 V solenoid valve (control), two-way throttle valve (control), 2 cylinder close to the switch (control) and a band As-i bus multi-pin interface (control) composition.
In addition, many air companies have abandoned “control everything from the air as a starting point,” the traditional view. To servo positioning
Technology, for example, the traditional approach is to first consider the use of pneumatic servo control means to achieve line of automatic positioning requirements, and now many companies have electric servo pneumatic Motor And stepper motor as the air samples were Sell . “Control is a means to exercise”, as long as the velocity and the more economic, more reliable, more convenient control of the control is the future direction of development. This pneumatic technology for the future development of the concept of opening up more clearly.
MM: Please talk about your company’s products and technology in which it has played a role in the movement and control.
Mr. Wang Xiongyao: Festo Corporation all products and technology are the pentagons around the Control mode to start, that sensor – Network – Processing – Executive – Software. And is therefore different from that of other air companies, Festo company’s early product range will include the supply of Sensor (Gas sensors, inductive, photoelectric, fiber optic sensors, etc.), software (PLC, Industrial Machines and products using the computational software). This is a company very early on pneumatic technology “control and movement,” the result of understanding the nature.
MM: Modern science and technology, including digital, electronic, IT, bus and Ethernet and other advanced technology to the development of motion control technology, which brought far-reaching impact?
Mr. Wang Xiongyao: Trigger the further development of computer technology micro-chip prices continued to decline. Market micro-chip technology in the decentralized units and applied a number of sensors. Currently, Expert Are working hard to hope to achieve in industrial Ethernet IP data 100% secure transmission. If the Ethernet to complete TCD / IP protocol optimized for machines and systems. From the data processing point of view, can be fairly easy to shop and Automation Office Connected. This data via the Internet Highway , With Ethernet up to 10G per second, the high transfer rate makes the Ethernet technology will eventually become the field of industrial automation, information delivery throughout the carrier, can realize remote maintenance equipment thousands of miles away.
MM: Motion control integration is an important development trend of production technology, which includes technology integration, system integration and functional integration. Please talk about the integration of motion control technology development.
Mr. Wang Xiongyao: The future development of pneumatic components to make a prediction, it will have lower power consumption, electromagnetic valve appeared to meet the As-i bus control to “plug and play” products for the capture system on behalf of the modular pneumatic device will more and more.
Cylinder will not just pure implementation of the components, will be the axis with intelligent features, which the control valve, control circuit and a variety of sensors integrated whole.
MM: Finally, the ability to briefly outline the development of motion control technology at home and abroad and the application process, the Chinese and foreign products and technologies in the motion control the supply and production capacity, and the application of what gaps exist? How to shorten the gap?
Mr. Wang Xiongyao: China motion control technology development and application of advanced countries, there is a big gap between the main components of the performance reflected in the. Adoption of new technologies, new processes, new materials will be to narrow the gap between an effective way. Such as nano-technology, nano-coating may improve the material’s surface finish, hardness, can also greatly reduce the friction coefficient between material and wear (including Piston Rods and seals, valve and seal between the friction coefficient). So on the air quality of the product has a number of almost-stage increase, expected life of the valve tends to be “infinity” and also look forward to the elimination and maximize the pneumatic servo system to improve the creep phenomenon and to improve the accuracy of pneumatic servo position control. Similarly, nano-coatings and nano grease product applications in the drive will greatly help improve the life of pneumatic drives. As the nano-coating is not resistant to resolve the defects, so the plastic can be replaced by nano-coating Aluminum System materials, metal processing time can be significant savings.
Also one on the computer chip technology. With the introduction of nanotechnology, the miniaturization of computer chips, once mass production, costs dropped dramatically, many distributed devices, sensors are embedded within the smart chip, so that each field device can be connected directly to the Internet, its state at any time, any place can always check, remote control, diagnostics and maintenance of this has substantial implications.
