Introduction
Air data bus systems often contain a general purpose computer to perform the treatment of certain functions and data to other systems. Some common examples are the tasks on the computer, radar processor, RSA and misery. Each system is often highlighted input / output (I / O) may vary but all have the same purpose - to translate electrical signals from one protocol to move to another place.
If I / O modules, computers used in the same team Maximum of laboratory tests and / or a computer via a local area network (LAN) is associated with the exchange of information. Some methods are the star, or road network. Data has a bus-speed electronics not working / PC fast as processor speed, but is much faster than a bus connecting Lintels pound face.
There are many bus Lintels prevalent in aircraft systems. The most common is the SR-232, RS-422, RS-485, IEEE-488 (GP-IB/HP-IB) and MIL-STD-1553, MIL-STD-1773-performance fiber bus 1553 and can in the future if it is necessary that the technology improves sensitivity, to reduce emissions, or used for other reasons.

MIL-STD-1553
Networks Made Simple MIL-STD-1553 is a network of bus LAN lorigine development of aircraft and now used on satellites, rocket launchers, vehicles, ships and ground stations. The machine itself is a twisted pair cable has a characteristic impedance of the 77th How it works great exercise Dune balanced transmission line is 75 kHz and 1 MHz, each order is to stop non-inductive resistance 77th The signal is not set lead to distortions in the data signal, a hope that can cause errors. Line and the rate of long-term interests better than most could have been a mistake. Terminators are the most valuable commercial standard 78puisque more. The value of the nest of resistance is not critical, usually 2% or ± L1 cable itself can be harmful 70-85, must be assessed at least 1 / 2 watt, 2 watts, and preferably a good safety margin cycles and high temperatures.
Resistance carbon should be avoided because of its high temperature coefficient. Shield provides protection and susceptibility to EMI and power beaming. In most applications, space is insufficient, but can be used for flight critical applications, dual protection, and double-shielded with mu metal sheet for EMP protection. If May, more difficult to imagine that in other cable shields add weight and increase labor costs. Note 2: The standard requires that all applications) and ask subsystems and equipment for the bus of the processor and two resistors (called Matchmaker, so much. And the processor and team. Resistors isolate the fault in the circuit of the socket with the heel or the device can switch to the practice of each network. See Figure 1, the power system 52 manufacturer and 59selon. Values are not critical activities . This is a demarcation line between the legs of each processor. They are also rated as less than 1 watt, non-inductive.
The maximum size of data Nya possible through the heels on the bus and the resistance of conductors. Buses, length of over 1000 meters and buses operating at only 300 meters. 1000-meter buses are usually only 2 or 3 men in a short period of goodness men minimize and reduce the risk of problems. Other bus 22 AWG or 20 AWG is recommended to reduce ohmic losses. Stub length is 20 meters. That line is goodness. Bus tolerate small pieces, and the few who can do better than the design of the bus, along with some movements. And bus network running long and heel, really, but usually a wide range of principal, interest, and many of the heel usually causes long-term problems, such as signal for the current strength brighter reduce the resistance of the driver and reflections from the terminal connector and other potential asymmetry in the system. The highest levels in the low level of regulatory issues thought.
Refer to the connector, but not rated to hold 75 of the current account and a line is a balanced transmission line. Capacity between and outer shell (the ground) is much smaller than the capacity between Interior and . Therefore, connections are minimized and on-line. Many systems are based on cleaning and maintenance of ports for future growth. If this happens, it is necessary to ensure that all validation and testing is a dummy load of unused positions of the current situation in the worst cases. Rated load is usually between 1000 and 3000ma should be elected to the cable on real and devices are connected, can prove. When the system is ready to oversee the inspection of cargo may be replaced by a protective layer. This usually leads to a little more margin for indicator of effectiveness. Again, the dummy load, assessed on non-inductive resistance least 1 / 2 Watt. EMI and keep the lid on a clean surface.
This is because the new 1553 and prevents rare , multi-plugs can be done because they feel that their ideas for improving the intermediate state (75 is too high. These fears proved exaggerated, and now 4 hours 5 hours or heel switches are frequent and some systems use 10-stub links. also increasingly living up to the on-line systems, the lowest score and heel, practice in the worst-heel Dark Chip finished interior and exterior was not in compliance. a bus. This approach has the lower part of the project easier and more reliable bus connector. In 1553, became the network Prototyping Board network processors, and maintaining a balanced transmission line. Each method is to react to these two items for sale. Not ohmmeter TDR (Time Domain reflection) is sufficient. The system works well, is that the system is correct.
Protection of the officer in May, short interest in a large error in some circumstances, EMI, the system has worked well for the rest. Short balanced system to protect the head unshorted information always (albeit at a lower level) but is not protected, and are sensitive to electromagnetic interference. As you can see, 1553 dune system simple mistake. They are very reliable and forgiveness. But like most things as a break too many rules and parameters that you have a problem. It is better to see what they have and decide how to improve gradually to reduce the elements that will not break so many rules.
