With the rapid development of the global economy and the increasing exchanges between regions, the ideal blueprint for the “global village†is gradually being realized. As an important means of transport to achieve the "global village" - the aircraft is increasingly integrated into the lives of ordinary people. Although the speed of the aircraft is very fast, the flight time from Asia to the Americas, Europe, Europe to the Americas and Australia is at least a dozen hours or even twenty hours. Such long-distance long-haul aircraft is exhausting. Many people are preparing a large number of books and magazines, and even bring their own electronic entertainment equipment to spend such a long flight.
However, in China, the challenge for aircraft is not only the rapid development of high-speed railways, but also the formation of high-speed rails over many cities. Many domestic airlines are trying their best to attract more people to fly. Instead of choosing a high-speed rail. For example, sacrificing profits with ultra-low discount fares or using more comfortable ground pick-up services to win customer satisfaction. All of these services are built on the premise of reducing airline profits.
In fact, the aircraft has an organic entertainment system very early. The current on-board entertainment system is to provide a large screen or multiple small screens on the plane. People can only watch the fixed programs of the airlines. The movies that may be played are not. What you want to see, maybe because of the angle and distance, the screen you see is very unclear.
Now, if you often take a transoceanic or large aircraft, you will find an in-flight entertainment system in front of each seat. You can choose the movies, news, music channels, and games you want to watch. The onboard entertainment system has become an important weapon for airlines and even for high-speed rail. With such an on-board entertainment device, you will find that taking long-haul flights is no longer a torment, but more like a relaxing holiday!
The aircraft's electronic system basically uses embedded computing technology. The airborne entertainment system is part of the aircraft electronic system, and naturally agrees to use advanced embedded computing technology to achieve. How to install an entertainment system on a new aircraft or an old model, EVOC's extensive experience in the embedded industry will help you.
The main technical requirements for airborne entertainment systems are:
a) high performance, small size, light weight, and reinforcement characteristics;
b) can be applied to harsh environments and wide temperature conditions on aircraft;
c) meet the I/O requirements for avionics applications;
Third, the system descriptionConsidering the limited space on the aircraft and the limited weight, we recommend using the 3U CPCI platform to provide high performance while minimizing the use of weight and space.
a) CPC-3813-MIL is a 3U CompactPCI computer motherboard with an Intel i7 processor. This motherboard can be used as a system or non-system slot single board computer. At the same time, advanced power management technology is adopted, and the whole machine adopts fanless heat dissipation. Externally provide VGA/DVI, USB, COM, network port and other IO interfaces, and all use aviation plugs to meet environmental requirements. Wide temperature range from -40 ° C to +85 ° C;
b) Arinc 429 standard for data communication on the aircraft and Arinc 429 data communication using A429 card;
c) Use 3U CPCI Ethernet switches to enable network communication for multiple airborne equipment.
