Accompanying drawing explanation
Fig. 1 is the structural frames utilizing train signal to realize wireless transmission channel distributor of the present utility model
Body.
Detailed description of the invention
Below with reference to figure, this utility model is given elaboration further.
Referring to Fig. 1, in the present embodiment, this kind utilizes train signal to realize wireless transmission channel distribution
Device, including: being electrically connected to the detection device 3 of headstock dynamical system, described detection device 3 is used for examining
Surveying electric switch key, detection device 3 is electrically connected to relay 2, and described relay 2 is electrically connected to train
Controlling device 1, described control device 1 is electrically connected to vehicle-mounted car ground AP4, described vehicle-mounted car ground AP4 and leads to
Cross the wireless interconnection that communicates with trackside AP5, when the detection device 3 in a wherein headstock of train detects electricity
During door key, driving relay 2 to close, described control device 1 detects relay 2 closure signal,
Determine travel direction, 36 channels are distributed to described vehicle-mounted car ground AP4,52 channels is distributed to described
Trackside AP5.
More specifically, described relay 2 is electrically connected to control the GPIO end of device 1, described GPIO
End uses M12 adapter.Wherein, described control device is CPU.
Utilize train signal to realize wireless transmission channel distributor to be respectively arranged on row described in this embodiment
In the headstock of car and the driver's cabin of the tailstock, headstock and headstock are relative concepies herein, i.e. real time running direction
Driver's cabin place end be headstock, then the other end is the tailstock.Above-mentioned detection device 3 is electrically connected to driver's cabin
Interior dynamical system or power system, when driver starts electric switch key, when i.e. starting train, drive rapidly
Motor type relay 2, is given the triggering signal controlling the modes such as device 1 pulse, now, controls by relay 2
Device 1 can judge that now this end is as headstock automatically, and This train is bound for XXX, thus controls communication, distribution
Channel gives vehicle-mounted car ground AP and the other AP of car.
It is assumed that TC1 is train one end, TC2 is the train other end:
When TC1 is travel direction, it is assumed that this time TC1 compartment is travel direction, driver's rotary switch key
Spoon, relay 2 be in closure state TC1 the GPIO of vehicle-mounted car ground AP4 detects and negates, TC1
Vehicle-mounted car ground channel automatically configures channel 36；The other AP of TC2 car, is not detected by relay signal, silent
Think channel 52.
When TC2 is travel direction, it is assumed that this time TC2 compartment is travel direction, driver's rotary switch key
Spoon, relay 2 be in closure state TC2 the GPIO of vehicle-mounted car ground AP4 detects and negates, TC2
Vehicle-mounted car ground AP4 channel automatically configures channel 36；The other AP5 of TC1 car, is not detected by relay letter
Number, it is defaulted as channel 52.
The GPIO mouth of AP uses power itself to be 3.3 volts, and electric current is 50 milliamperes, it is not necessary to outside carries
Power supply source.
Foregoing, preferred embodiment the most of the present utility model, it is not intended to limit of the present utility model
