On the railway, the radio wave never disappears

Looking back at the development of railway communication equipment, from the overhead light lines of the steam locomotive era to the cable carrier waves in the era of internal combustion locomotive; from digital communication in the era of power locomotives to fiber communication in the high -speed railway era ,Stablize.

And wireless reporting machine

1980s

"Shunfeng Ear" of railway communication

Has an extremely important role

This device that looks like "Baby antenna"

It's our protagonist today

XB-D1 semiconductor short-wave radio station

Also known as wireless report machine

Don't look at it "petite body

It was the railway emergency rescue communication at that time

Core burden

In the 1980s, the train was slow and the information transmission was slow. Information transmission on the railway mainly depends on cable communication carriers to achieve. When cable communication is interrupted, wireless sending machines need to be used to achieve wireless calls and reports.

In the 1980s, the telegram of the telegram in the telegram continued. One day, the employee's eyes were full of telegraph code, and the ears were buzzing ...

At that time, there was no interval automatic phone call, no mobile signal and mobile phone. As an important communication equipment for railway rescue, wireless sending machines need to rely on hand -shaken power generation to power supply. With the development and progress of railway communication technology, wireless reporting machines have completed their historical mission and withdraw from the front line.

A small wireless sending aircraft carried the mark of the times and witnessed the rapid development of the railway communication industry.

From the rice rail to the quasi -rail, from the general iron to the high -speed rail, the speed of the train is getting faster and faster, and the railway communication also plays an important role in railway transportation.

Times are developing technology in innovation

The future of China Railway

We wait and see
