Three major business opportunities in the field of industrial control with a high probability of nuggets

Due to the four trillion yuan economic stimulus plan launched by the Chinese government, more than half of the money is invested in the construction of major infrastructure projects, such as railways, highways, airports, and ecological environmental projects (such as wind power, LED lighting, solar power, etc.), Therefore, there are still many opportunities for nuggets in the field of industrial control in 2009, among which the three largest business opportunities are green power generation, LED lighting and power over Ethernet.

Green power generation mainly refers to wind power and solar power. The use of renewable energy wind and solar power can not only reduce the demand for thermal power plants that seriously pollute the environment, but also greatly reduce carbon dioxide emissions. Once it can be commercialized on a large scale, it can not only create a sustainable ecological environment of blue sky and blue water for future generations, but also make a substantial contribution to the energy saving and emission reduction goals of the Chinese government.

Because wind and solar power stations are mostly built on harsh mountains or in the wild, they not only require their signal acquisition, amplification, filtering, control, and drive systems to be highly reliable, but also require remote communication capabilities. Obviously, the traditional high-reliability programmable logic controller (PLC) can no longer meet this complex calculation, control and communication requirements, but must be given way to the rapid rise of programmable automatic controllers (PAC) in recent years.

At present, the main PAC suppliers in the industry are Advantech, GE Fanuc, Mitsubishi Electric AutomaTIon, Rockwell AutomaTIon, NI, Opto 22 and Bosch Rexroth. Considering that most readers may not know PAC well, this cover story will give you a detailed Introduce the current industry's main power to promote PAC to replace PLC, the main performance of PAC, other major applications of PAC, and how to use PAC to achieve complex industrial field networking, communication and control tasks.

LED lighting has now become the mainstream development trend of home lighting, automotive lighting, general lighting, landscape lighting and street lighting, because it is different from existing incandescent lamps, compact fluorescent lamps (CFL), linear fluorescent lamps, halogen lamps and high-intensity gas discharge lamps. Compared with (HID), it is the only lamp that does not require high-voltage startup. The 6W LED lamp can produce a greater brightness than the 44W halogen lamp, and the power consumption is only about 1/6 of it, so the LED lamp can greatly save power. Not only that, LED lights are small, rugged, and have a long service life, and they do not contain toxic substances like CFLs.

Since about 19% of the world's electricity is used for lighting, reducing this part of the electricity consumption will produce a considerable energy saving effect. In view of this, the industry is constantly working to find more energy efficient lighting solutions for the general lighting market. In addition, in recent years, as green environmental protection groups continue to expand the energy conservation and environmental protection boundaries, various normative standards organizations continue to issue new energy efficiency standards, and terminal products continue to develop toward higher integration and smaller sizes, reducing energy consumption and improving energy use. Efficiency has become a common concern of governments, industry organizations, semiconductor companies, electronic product manufacturers and consumers in many countries around the world.

These market drivers have made the LED lighting market very bright. Jeff Shepard, president of market research company Darnell Group, also pointed out: "General lighting, medical and architectural LED lighting applications will show a long-term compound annual growth rate of more than 90% in the next five years, and this growth potential will be immediate in 2009 Show up. "

In order to help readers better grasp the business opportunities of the LED lighting market, this issue of the magazine has organized three articles on efficient TRIAC dimmable LED drivers, home LED lighting below 25W and 200W LED street lighting solutions, and will also organize a tablet in the next issue. TFT-LCD display LED backlight solution article, I believe readers will benefit greatly.

USB power supply has now become the standard design of many popular consumer electronics products. Similarly, Power over Ethernet (PoE) will soon become a standard design in industrial control applications because it can save a dedicated power cord and effectively help Customers further reduce deployment costs, maintenance costs and inventory costs. PoE is currently mainly aimed at VoIP phones, security cameras and wireless access point applications. In the future, it will also be applied to video conference stations, RFID readers, PTZ security cameras and longer-range carrier-grade wireless access points. This design column will introduce you to the latest PoE solution.
