A person who is far from radio electronics and electrical engineering in general sometimes becomes "uncomfortable" when he finds himself in the circle of professionals who speak an obscure specific dialect. It is here about programmable logistics controllers, relays, modules, inductive sensors and others.
It may seem that these people have some kind of mystical knowledge, inaccessible to the common man.
On the principles of automation "on fingers"
But not everything is so scary, friends! The basic principles of any automation are quite "edible" and are not out of reach for understanding. The principles are constant!
Diverse and very complex are the technical solutions by which they are implemented in practice. And knowing the principles, you can already safely ask questions to a professional, based on your technical task in production or the situation in everyday life.
So, any automatic device is based on the principles of the theory of automatic control. And it says that to manage something, you always need:
-
Input data (any information about the control object that we operate);
-
The center where this information is analyzed and a decision on the control action is taken;
-
Managing influence (product of the above center's activity, to change something that he "did not like").
And that's enough! The rest of the variety of names is very difficult to remember; a layman does not need to know this. Here are just the main terms.
Input data
Sensors are engaged in the collection of input data, they are selected depending on what exactly we need to control. There are many types of them. Here is not a complete list:
-
photovoltaic;
-
inductive;
-
barrier;
-
temperature sensors;
-
mechanical sensors.
Logical information processing devices
At the present time, these are masterpieces of engineering, created on the basis of microcircuits. They are combined with sensors and control devices. Basic:
-
controllers of all types;
-
programmable terminals;
-
human-machine interfaces.
Control Devices
Devices that have a direct impact on the control object .:
-
linear motors;
-
servos;
-
frequency converters;
-
various relays;
-
display devices.
It is enough to know which of the 3 positions is occupied by the desired part or device in order to roughly represent, in which
