The development of system.
For example, in order to adapt to the development of railway communication technology, bimodulus goods row tail repeater provided in this embodiment has together
When the function that goods train end information and 400MHz number goods train end informations are relayed is simulated to 450MHz.There are the yards of feeble field
Interior, 450MHz simulates Train End Equipment and the operation simultaneously of 400MHz numbers Train End Equipment, believes the number from row head or row tail
It number is forwarded and either the analog signal from row head or row tail to be forwarded, solve the problems, such as the feeble field in yard.Wherein,
First processing module and Second processing module can realize that the present embodiment is not particularly limited this by CPU.
Further, on the basis of the above embodiments, the basis is monitored second launching frequency
Monitoring information handles the first information or handles the first response message received in second launching frequency, to realize
The communication of the row head and row tail of the train, including：
If being not received by first response message in second launching frequency in the first preset time period, cut
First launching frequency is shifted to, the first information is forwarded to the row tail of the train, and again switches to described second
Launching frequency judges whether receive the second response message in second launching frequency in the second preset time period；
If receiving the second response message in second launching frequency in the second preset time period, by described
After two response messages are forwarded to the row head of the train, switch to first launching frequency and to it is described first send frequency point into
Otherwise row monitoring switches to first launching frequency and is monitored to the first transmission frequency point.
Further, on the basis of the various embodiments described above, further include：
It, will if receiving first response message in second launching frequency in first preset time period
First response message is sent to the row head of the train.

CPU is mainly responsible for digital radio station communication all the way, digital signalling logic judgment forwards, power supply is converted, for work such as electro-detections；It is another
Road CPU is mainly responsible for analog radio communication, the work such as analogue signalling logical forwarding judgement.Two-way CPU is respectively to 400MHz numbers
Standard information and 450MHz analog system information carry out data processing and forwarding.
Complete machine uses two sets of antenna transmission systems, respectively to 400MHz digital systems information and 450MHz analog systems information into
Row sends and receives；But this structure develops the main structural framing for borrowing WZCK800-I passenger train tail repeaters, standing-wave ratio detection
Module can only place 1 tunnel, only can wherein carry out antenna feeder standing wave all the way to 400MHz numbers antenna feeder or 450MHz simulation feeder lines
Than detection, since 450MHz is modeled as transition frequency point, 400MHz digital systems are mainly used later, so standing-wave ratio module pair
400MHz antenna transmission systems carry out standing-wave ratio performance monitoring.
This equipment meets 400MHz digital systems information and 450MHz analog system information forwarding capabilities, can make for scene
It is matched with demand, the list radio station M8220 can be used to realize forwarding and prison for single 400MHz numbers or 450MHz analog systems
Auditory function.Execution unit will need the signaling of forwarding to be sent to data by protocol format after the communication signaling and logic judgment after parsing
Processing unit storage, display.It is communicated using RS232 interface between data processing unit and execution unit；Execution unit and channel
UART interface is used according to the definition of channel device interface between machine.

(2) signaling forward process work main flow
Digital alien frequencies pattern CPU workflows：After repeater powers on and digital radio station is waited for start, it will wait for
400MHz number locomotive platforms are sent on frequency point, and locomotive platform is waited for send signaling (note：400MHz numeric column tail systems are received using alien frequencies
Send out working method).
After repeater receives the signaling that digital locomotive platform is sent, repeater is switched to row tail launching frequency and waits for, if 3s
The corresponding response signaling of corresponding train tail host is not received inside, then is switched on locomotive platform transmission frequency point and the locomotive platform is forwarded to believe
It enables.It is switched to row tail launching frequency after battery has fired, if receiving the corresponding response signaling of corresponding train tail host in 3s, is arranging
Tail host sends and forwards the train tail host response signaling on frequency point.If not receiving corresponding row tail response signaling yet, relaying
Device, which is switched to locomotive platform launching frequency, to be continued to wait for.
It when the repeater free time, waits for and is sent on frequency point in locomotive platform, wait for locomotive platform to send signaling, at this point, repeater is not
The signaling of train tail host transmission can be received.It is waited for when locomotive platform and stays in respective column tail host response signaling in row tail launching frequency etc.
When, row tail ID is judged, to receiving the train tail host signaling of non-corresponding without processing.
Simulation is the same as frequency pattern：It is modified processing just for agreement using passenger train tail repeater program of lower computer flow.
