机械设计的点滴体会5（Experience of mechanical design 5） When people walk through the jianchuanlibao strong era, no matter what devices are gradually with automation components. Even though it is fully manual today, Im afraid it will have to be automated one day. The quality of automation system is sometimes crucial, aircraft design Sukhoi Design Bureau and Mikoyan design bureau are first-class, on the aerodynamic and dynamic characteristics of the world, but the difference in the combat strength of the computer system and automatic control system. The United States is the B2 flying wing aerodynamic layout, from aerodynamic layout point of view there is no possibility of artificial manipulation, that is to say, if stopped the automatic flight control system of the rudder, it will soon fall from the sky, artificial is the fundamental can not control its rudder. Thus, a good automatic control system is very important. When it comes to automatic control system, we all feel very magical, feel that learning automation is a good thing, make automation guy also very impressive, in the site, if you find out who dressed clean, that guy is probably the guy automation. In fact, the automatic control system has a development process. In the early years, the relay interlocking system was basically used. The coil of the relay is connected with a switch, the coil is energized and the armature is pulled in, and the original normally open contact is closed, and the circuit below is controlled to electrify. The normally closed contact is opened, and the circuit which controls the original connection is disconnected, and the logic control is realized. If you put these basic things to remember that, even if it is to control the computer era, but also is in the computer there are numerous contacts in your control work, think of these things, you will not panic, dont be afraid to do automation guy, no matter how high. As long as one layer to find control problems, one by one point to find, whether
