Description
Technical field
The present invention relates to it is a kind of can according to a semaphore state simultaneously control more differences shunt protection transponder tune
Vehicle guard system.
Background technology
Distributing shunt guard system be by trackside control device acquire coherent signal machine lighting power supply, realize to control
Control equipment is powered, while according to the state of signal lighting power source, corresponding message data being selected to export to active balise,
To realize safeguard function of shunting.Monitoring device is equipped in system chambers of relieving a garrison, using existing signal lighting power source circuit,
By PLC technology, the real-time communication function with outdoor control device is realized, obtain working state of device of relieving a garrison, alarm
The information such as information, message output state.It, can be for the system of relieving a garrison since semaphore is under the premise of maintaining itself normal work
The power limited that equipment uses, therefore the application model for only having a frame semaphore to correspond to an active balise at present.
According to《The provisional technical conditions of MTU depot (institute) guard system of shunting》Middle requirement, protective device installation site of shunting exist
20 ± 0.5 meters of guard signal machine foreign side, cannot be less than 15 meters in special circumstances, but Motor Car Institute part signal in practical application
There is track switch within the scope of 15 meters of machine foreign side, this results in a frame semaphore and needs corresponding two routes (straight stock and side two groups of responses of stock
Device), and all guard systems of shunting cannot meet the demand at present.But according to full protection scene Safety of Shunting Operation
Needs, Special zone safeguard function of shunting is essential again.

Specific implementation mode
With reference to specific embodiment, the present invention will be described in detail.Following embodiment will be helpful to the skill of this field
Art personnel further understand the present invention, but the invention is not limited in any way.It should be noted that the common of this field
For technical staff, under the premise of not departing from inventive concept, various modifications and improvements can be made, these belong to this
The protection domain of invention.
In Standard balise system, such as Fig. 4, transponder interface is that the C1 data being connect with indoor trackside electronic unit connect
Mouthful, C6 energy interfaces, be A1 rf data interfaces with the wireless interface of mobile unit, A4 RF energy interfaces, train it is vehicle-mounted
Equipment supplies energy to active balise activation when by active balise, by car antenna unit by A4 interfaces, active
Transponder sends the message from LEU (trackside electronic unit) to mobile unit by A1 interfaces and is used as control vehicle signal input.
The present invention is to have carried out creative transformation on the basis of Standard balise system, and formation is suitable for security application of shunting
Customization special screne guard system.
This system is shunt protection with the distributing of single-point dual control below by shunting protective device and message transmitting device forms
For system, as shown in Figure 1, between the two by cable as transmission medium；To realize that autgmentability needs to carry out power
Preferably distribution, therefore existing protective device output interface of shunting (including C1 data-interfaces, C6 energy interfaces) is adjusted
It is whole, only retain C1 data-interfaces, the protective device consumption power that makes to shunt is greatly reduced, and can power headroom be used for multichannel message
The data transmission of transmitting device (at least supporting 4 tunnels or more)；Certainly, depending on specific application conditions, special as one shows
Example, the scheme that protective device output interface of shunting only retains C1 data-interfaces can also be used for only being configured with single channel message transmissions dress
The application scenarios (or operating mode) set.
Mobile unit is by protection transponder group of shunting (including message transmitting device+passive balise all the way, wherein reporting
Literary transmitting device receives the transparent transmission message from protective device of shunting similar to active balise) when, it needs to receive transponder group
Interior all transponder message informations are as control vehicle signal input, when there is some transponder information loss in transponder group,
Mobile unit can make corresponding actions to ensure vehicle safety.
As shown in Fig. 2, protective device acquisition semaphore lamp position status information of shunting, the input item selected as outgoing message
Part, selectes corresponding memory (such as message ROM1~3 in Fig. 2), and FPGA reading memory datas are simultaneously adjusted to DBPL volumes
The C1 signals of code externally export.Inside can by PLC technology to indoor transmissions shunt protective device working condition, report
The information such as alert state.
FPGA while the power state information of Signal lighting unit front stage is acquired inside the equipment of protective device of shunting,
Respectively status condition 1,2, when two-state information compare it is consistent and for legal state information when, it is just corresponding to the state
Data (such as message data) on memory are read out；
FPGA internal hardwares logic module is independent, and there is no the hidden danger of wrong choosing between each road memory；
Judgement is compared for the memory data read inside FPGA, stops external data when data exception
Output.
Output signal is the C1 interface signals of DBPL codings, compares the C interface signal of standard, eliminates C6 energy components,
And the amplitude of C1 signals is reduced, the external output power of protective device of shunting can greatly be reduced, and do not influence the biography of data
It is defeated.Therefore can have autgmentability.
Its energy source only provides energy by A interfaces and ensures that the equipment of message transmitting device works after removing C6 interfaces.
As shown in figure 3, message transmitting device receives the C1 interface signals from protective device of shunting, through FPGA demodulation-tune
System sends message information with fsk signal to mobile unit.When protective device of shunting is without output, message transmitting device can be external
From the acquiescence message of body storage.
Message transmitting device is not changed by the way of transparent transmission, for transmission data, therefore does not undertake data peace
Global function；
By the presence or absence of DBPL codes inside message transmitting device, to realize the identification of state, the interlocking on hardware logic is protected
Card message transmitting device can only operate in single message and send state.As shown in figure 3, in the presence of C1 signals, signal turns
1 output control 1 locking of signal acquiescence message ROM is changed, states of the acquiescence message ROM without output controls signal as control signal 2
Conversion 2, FPGA is input to by C1 signals, externally exports the message data from protective device of shunting after processing；When C1 signals
When missing, 1 output control signal 1 of signal conversion makes acquiescence message ROM work, output acquiescence message to FPGA, at this time acquiescence report
Literary output state controls signal conversion 2 as control signal 2, and C1 signal lockings can not be exported to FPGA, FPGA is defeated at this time
Out from the message data in acquiescence message ROM.
To sum up, using this technical solution, it can be achieved that control of the mono signal machine status information for the above transponder of two-way, and
Have the ability of more multichannel extension, meets the related needs in live practical application, with lower equipment cost, maintenance cost
It realizes more function of safety protection, improves the safety prevention measure in guard system of shunting.
The foregoing is merely the preferred embodiments of the present invention program, are not intended to limit the scope of the present invention.
Any modification, equivalent replacement, improvement and so on all within the spirits and principles of the present invention should be included in the present invention's
Within protection domain.
