The temporal information for the data traffic signal that temporal information and the virtual level receive, and according to the temporal information, by institute
It states the data traffic signal that the data traffic signal that physical layer receives is received with the virtual level to be integrated, generates traffic
Then the traffic signals real time data is mapped to physical layer, and saved to the memory module by signal real time data.
When physical layer and virtual level all receive data traffic signal, the operation conditions of optical fiber telecommunications line at this time is represented
To be obstructed, in order to guarantee data traffic signal transmission integrality, traffic signaling equipment use simultaneously optical fiber telecommunications line and
Wireless communication line transmits data traffic signal to central traffic signal control subsystem.
Since optical fiber telecommunications line is obstructed, there is intermittent phenomenon, therefore physics in data during transmission
The data traffic signal that layer receives also can be intermittent.In addition, judging that optical fiber telecommunications line is obstructed in network arbitration device
Freely, it opens the moment of wireless communication line, data traffic signal is not transferred to virtual level from wireless communication line, that is,
It says, although wireless communication line is during transmission there is no data are lost, it is being opened and is closing
Moment, data traffic signal will not be transmitted from the route, and therefore, the data traffic signal that virtual level receives is opened just
The problem of moment for beginning to transmit and terminate to transmit is also likely to be present loss of data.In this case, the embodiment of the present application passes through

To the memory module.
In one implementation, central traffic signal control subsystem has been internally integrated true physical layer network interface
And the network interface of virtual level, central traffic signal control subsystem can be according to used in current transmission data traffic signals
Communication line, automatically selects corresponding network interface, establishes connection with traffic signaling equipment.If current transmission communication line is
Optical fiber telecommunications line then carries out the reception of data using true physical layer network interface；If current transmission communication line
It is wireless communication line, then carries out the reception of data using the network interface of virtual level, and be current by virtual level network mapping
The traffic signaling equipment at crossing；If current transmission communication line is wireless communication line and optical fiber telecommunications line, simultaneously

Unification for the ease of data is stored and is used at any time, and central traffic signal control subsystem will uniformly receive
Data be stored in the memory module of physical layer.Specifically, directly data are protected when physical layer receives data traffic signal
It deposits to memory module；When virtual level receives data traffic signal, central traffic signal control subsystem is then by data
After physical layer is mapped to from virtual level, saving to memory module；Traffic signals number is all received in physical layer and virtual level
According to when, then both extract the temporal information in data, integrate the two data according to temporal information, it is real to generate traffic signals
When data save to memory module, realize mapping of the data from virtual level to physical layer.
Further, the network arbitration device obtains the Network status of the optical fiber telecommunications line, comprising:
The network arbitration device uses the optical fiber telecommunications line, and Xiang Suoshu central traffic signal control subsystem sends test

When the current operation conditions of the optical fiber telecommunications line is to disconnect, using the wireless communication line, by the traffic
Signal data is transmitted to the virtual level of the central traffic signal control subsystem.
7. system according to claim 6, which is characterized in that the data processing module is also used to:
When the only described physical layer receives the data traffic signal, directly the data traffic signal is saved to described
Memory module；
Alternatively,
When the only described virtual level receives the data traffic signal, the data traffic signal is reflected from the virtual level
It is mapped to the physical layer, then saves the data traffic signal to the memory module.
8. according to the described in any item systems of claim 5-7, which is characterized in that the Network status obtains module, comprising:
Test cell, for using the optical fiber telecommunications line, Xiang Suoshu central traffic signal control subsystem sends test number
According to packet；
Receiving unit is fed back using the optical fiber telecommunications line for receiving the central traffic signal control subsystem
Response data packet；
Network status acquiring unit obtains the optical fiber telecommunications line for the reception condition according to the response data packet
Network status, wherein when the receiving unit receives correct response data packet, obtain the net of the optical fiber telecommunications line
Network situation is that network is normal；Alternatively, obtaining the optical fiber telecommunications line when the receiving unit does not receive response data packet
Network status be network disconnect；Alternatively, being obtained in the response data packet that the receiving unit receives there are when Loss
The Network status of the optical fiber telecommunications line is that network is obstructed.
