Hereinafter, the part term in the application is explained, in order to those skilled in the art understand that.
Artificial semi automatic toll system (Manual Toll Collection, abbreviation MTC) is exactly existing manual toll collection
System.
Electronic toll collection (Electronic Toll Collection, abbreviation ETC) is in charge type high speed
On highway, charge station by the special short range communication between trackside antenna and vehicle carried electronic label, do not need to driver's parking and
In the case that other toll collectors take any operation, a kind of full automatic charging system of charge processing procedure is completed.
Compound password card (Compound Pass Card, abbreviation CPC) is a kind of having for MTC tracks
The compound password card of 13.56MHz Card Readers and 5.8GHz identification functions.
Roadside unit (Road Side Unit, abbreviation RSU) is in ETC system, mounted on trackside, is led to using special short distance
(Dedicated Short Range Communication, the abbreviation DSRC) technology of news, is communicated with board units, is realized
Testing vehicle register identification, the device of electronic charging.
Beacon service table (Beacon Service Table, abbreviation BST) carries path letter during ID of trace route path
Breath.
The course of work of existing CPC cards is as follows：
Fig. 1 is the structure diagram of existing compound password card.Fig. 2 is that the application scenarios of existing compound password card are illustrated
Figure.As shown in Figure 1 and Figure 2, when driver drives to highway MTC entrances, staff can be believed vehicle by card reader
In breath, access information write-in CPC cards, driver then is given CPC cards, clearance of arguing for the sake of arguing.After CPC cards detect access information, beat
No. 1 antenna (waking up antenna) of itself " 5.8GHz parts " is opened, CPC cards can be identified RSU wake-ups at this time；In area residing for arrow
Domain CPC cards are in the dormant state of low-power consumption；When vehicle passes through mark RSU and is waken up, main control part starts to switch to just
Normal operating mode, and No. 2 antennas (dual-mode antenna) are opened, CPC cards can complete entire ID of trace route path mistake with mark RSU at this time
Journey, and into suspend mode, wait for identification procedure next time or MTC outlets Card Reader charge.Driver is exported by CPC cards in MTC
It returns, fee-collector reads ID of trace route path information in CPC cards by card reader.Card reader is led to 13.56MHz Card Readers part in figure
Letter.
Since existing compound password card is waken up from dormant state, dormant state is in low power consumpting state, therefore calls out
Sensitivity of waking up is relatively low, causes the communication distance of compound password card and RSU in wakeup process shorter；And due in compound password card
Portion includes wake-up circuit, causes circuit more complicated, cost is higher.
The utility model is based on the above problem, proposes a kind of compound password card, does not need to wake up antenna and wake-up circuit, control
Molding block starts the 5.8GHz communication modules work and is marked with receiving the path that the RSU is sent every the first preset duration
Know information, sensitivity is waken up since the receiving sensitivity of 5.8GHz communication modules is more than, communication distance increase, and circuit
Simply, cost is relatively low.
The technical solution of the utility model is described in detail with specifically embodiment below.These are specific below
Embodiment can be combined with each other, and the same or similar concept or process may be repeated no more in some embodiments.
Fig. 3 is the structure diagram of compound one embodiment of password card provided by the utility model.As shown in figure 3, this implementation
The compound password card of example, can include：

The ID of trace route path information that the RSU is sent is received, and starts second timer；A length of second is pre- during the timing of the second timer
If duration；
Step C, when the timing duration of the second timer reaches, then start first timer, repeat step
B, until monitoring MTC export operations.
Specifically, when monitoring the MTC entry operations, start first timer, the timing duration of first timer
For the first preset duration N, when the timing duration of first timer reaches, it is pre- to start the 5.8GHz communication modules work second
If duration M, RX path identification information is waited for.At this point, starting second timer, a length of second is pre- during the timing of second timer
If duration M.If receiving the ID of trace route path information that RSU is issued within the M times, switching working mode to normal mode of operation, with
Entire ID of trace route path process is completed in RSU communications.When the timing duration of second timer reaches, then the first timing is again started up
Device repeats step B, until after monitoring MTC export operations, closes first timer, second timer and 5.8GHz lead to
Believe module.
Using the working method of timing receipt, be more than using the receiving sensitivity of 5.8GHz communication modules wake up sensitivity this
One feature, the working method of more existing " first wake up and receive again " are greatly increased on communication distance, are effectively avoided because logical
Spill tag caused by news distance is not enough and vehicle flowrate is big knows problem.
Using the working method of timing receipt, wake-up circuit part can be saved, PCB surface product is reduced, effectively reduces
The manufacture cost and circuit complexity of complete machine.
Fig. 4 is the application scenarios schematic diagram of compound one embodiment of password card provided by the utility model.Illustratively, as schemed
Shown in 4, vehicle enters MTC entrances, and compound password card is when monitoring the MTC entry operations, at a certain time interval, opens
