... In the days of satellite navigation and google maps, conservative railway workers are of the opinion that there is nothing better than outdoor (ground) reading devices. That's why they are conservatives, so we won’t talk about it ...
Today we will continue to talk about systems operating on the railway.
SAIPS - With the system A of automatic And identification P of the mobile With the left.
Everything is very simple. Every person, wherever he is, wants to know what happens to his things, in the absence of himself near them).
So we, railroad workers, just can’t sleep, we worry, where are our cars now, what’s wrong with them ...? (I'm exaggerating a little here, but you understand me).
Closer, as they say, to the point. How does it all work?
On wagons and locomotives, if you look closely, there are small iron boxes - these are code on-board sensors (CBD).
They encrypted information about the car and some other attributes. The sensors are programmed, but I want to tell you that only six-fold “flashing” is possible, after which the sensors become unchanged. However, this is quite enough.
The sensor is a passive microwave element, that is, it does not contain components for generating microwave signals. The principle of operation of the sensor is based on the modulation of the reflected microwave signal, which is generated by the irradiating and reading equipment of the reading point. Modulation is carried out in accordance with the identification code of the sensor.
Along the railway, in, let's call them control points, reading points are set.
I think their purpose is clear.
The reading point is a two-channel system for polling the parameters of a device passing by: a high-frequency channel for polling CBD sensors installed on locomotives and wagons, consisting of an antenna, a high-frequency, low-frequency path of the reader and a bunch of different parts.
The read information in encoded form is transmitted to the CC. Further, it is already properly processed and used for its intended purpose.
As always for general reference. Thanks for attention.

do not attribute myself to conservatives, but to whom it is interesting.
