Description
Technical field
The utility model relates to a kind of circuit, particularly a kind of automatic power-controlling device that is used for locomotive station based on GPS information.
Background technology
For improving railway transport capacity, China constantly builds new railway line, and builds new station when improving train running speed in recent years.Distance between two stations is also shortening, cause train at run duration thus, when driver and station or scheduling conversation, might exhale logical two or more stations owing to the locomotive station emitted power is too high, so not only influenced the operate as normal at adjacent station, and very easily caused danger.In this case, press for power is reduced, reducing closing on the interference at station, and after walking out this special area, power must be adjusted into normal value in order to guarantee proper communication.Rely on manual mode can adjust transmitting power at present, but, when adjustment is finished, may run out of this zone by train because locomotive speed is too fast.Therefore the mode of manual setting power can not satisfy present requirement far away.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of automatic power-controlling device that is used for locomotive station based on GPS information.
The technical scheme that the utility model is taked for achieving the above object is: a kind of automatic power-controlling device that is used for locomotive station based on GPS information, it is characterized in that: comprise control unit, GPS location switch unit, receipts/send out the channel device unit, described control unit is connected with GPS location switch unit, a receipts/channel device unit respectively.
The beneficial effects of the utility model are: can finish power control fast and accurately, reduce driver's operation, guarantee normally carrying out of communication, and guaranteed that other station is not disturbed, make traffic safety reliable.
