In another kind of specific embodiment, wakeup unit comprises: signal amplifies subelement and frequency-selecting subelement; Signal amplifies subelement and is electrically connected with frequency-selecting subelement, signal amplifies subelement and is also electrically connected with radio frequency unit, frequency-selecting subelement and control unit electrical connection, signal amplifies subelement for wake-up signal is amplified, and frequency-selecting subelement is for waking board units up according to the frequency of wake-up signal.In a kind of detailed description of the invention, when the antenna reception of wakeup unit arrives microwave signal, can pass through one or more levels high pass/bandpass filter, allow and pass through smoothly in the signal of 5.79GHz～5.84GHz frequency band, and other frequency signal inhibition decay is passed through, effectively reduce, as 900MHz, 800MHz, the signal of 2.4GH etc. frequency range by and enter in detecting circuit, detecting circuit carries out detection to the high-frequency signal of 5.79GHZ～5.84GHZ, remove high-frequency signal, demodulate baseband signal, and incoming signal to signal amplifies in subelement, for improving sensitivity, suitably carry out the faint amplification of signal, finally being input in frequency-selecting subelement through the baseband signal of faint amplification, detect the frequency of baseband signal, while making to only have the baseband signal input of 11KHZ～25KHZ, just can produce the interrupt signal that level changes, and each module of trigger control unit and board units enters wake-up states.Because signal amplifies subelement and frequency-selecting subelement through signal successively, when producing the baseband signal of 11KHZ～25KHZ, wakeup unit produces interrupt signal, and triggers board units and enter wake-up states.By amplifying subelement and frequency-selecting subelement, the signal of 5.79GHz～5.84GHz frequency band passes through smoothly, the microwave signal of other scopes will significantly be decayed, while only having the baseband signal of 11KHz～25KHz to be fed to the highly sensitive frequency-selecting subelement of low-power consumption, just can produce interrupt signal and deliver to control unit, wake control unit and unit module up, thereby reached low-power consumption, the high sensitivity wakeup unit that antijamming capability is strong.Signal amplifies subelement and is preferably the low multiple amplifier of signal, and frequency-selecting subelement can preferably include zero-crossing detection circuit, and zero-crossing detection circuit preferably adopts AS3933 chip.Adopt the frequency-selecting subelement of AS3933 chip as wakeup unit, there is the function that regulates sensitivity and frequency-selecting.The mode of operation of AS3933 chip is divided into listen mode and awakening mode.In the time of listen mode, working current is 1.7uA, is 2.7uA to the maximum, when the frequency of incoming signal meets the frequency point ranges of its setting, will exit listen mode and enter into awakening mode, and detect and obtain signal RSSI strength rating.In the time of awakening mode, obtain stable signal RSSI(Received Signal Strength Indicator, receive the intensity instruction of signal) strength rating, and produce interrupt signal, send to control unit, make control unit and other units enter wake-up states.Because frequency-selecting subelement comprises AS3933 chip, under standby mode, frequency-selecting subelement is in monitoring mode of operation, and control unit enters complete park mode, and the power supply of other modules is also turn-offed completely, in power-down state, has further reduced consumption of current.
In the embodiment that a kind of preferred OBU sensitivity is adjustable, control unit also can pass through radio frequency link, receive the sensitivity gear information that hand-held set obtains the pad value of board units reception signal according to windshield, then according to sensitivity gear information and the sensitivity gear information table prestoring, board units is adjusted to suitable sensitivity, in OBU use procedure, wakeup unit for waking board units up in the time reaching sensitivity.
Particularly, when OBU need to adjust sensitivity, hand-held set can obtain corresponding sensitivity gear information according to the pad value of test, by Wireless/wired signalling methods, corresponding sensitivity gear information is sent to board units, board units is according to the sensitivity gear information table of the sensitivity gear information that receives and storage (this table is provided with the corresponding relation between sensitivity gear and suitable sensitivity by empirical value), just can obtain its suitable sensitivity that wakes up.
Installing after OBU, in the time there is no information interaction, wakeup unit is in monitoring mode of operation, and its sensitivity is arranged on a certain gear value according to windshield to the decay of microwave signal, and control unit is in complete park mode.Now wakeup unit and control unit have power supply, but electric current is very little, and other each modules in board units are all in power-down state.In the time that board units enters the communication zone of roadside unit, wakeup unit receives wake-up signal according to the gear value arranging, produce interrupt signal to control unit, wake control unit up, control unit is opened the Power supply switching valve of other each modules, it is powered on, enter mode of operation, conclude the business, communicate by letter with roadside unit.For example, there is 1～4 four gear value, respectively correspondence-80dB ,-60dB ,-40dB ,-20dB wakes sensitivity up, when the sensitivity gear information value prestoring when board units is 2, represents that the sensitivity of corresponding uses-60dB receives the signal of reception.The number of concrete gear can freely arrange as required, as also can gear information value being set to 1～6.
The sensitivity gear information value prestoring can be used hand-held set or other check implements to arrange, after completing sensitivity gear information value and arranging, if gear is inaccurate, can use a gear that card is set gear is adjusted, specific practice is, card of every insertion, gear just fall one grade or rise one grade, be that the gear of storing in current control unit is 3, insert 1 card and just become 2 or 4, insert and just become 1 or 5 twice.If do not used hand-held set, also can use card that gear is set, if gear is 6 or 1 to insert card when board units is initial, card of every insertion rises one grade or fall one grade, thereby only regulates with setting and later stage that card carries out gear.
After board units and roadside unit have been concluded the business, transfer default sensitivity gear information by control unit, and use this gear information that the sensitivity of wakeup unit under readiness for action is set again.Conventionally in following three kinds of situations, control unit can import to the sensitivity gear information prestoring in wakeup unit: 1, when installation car carrier unit; 2, when user's plug-in card; 3, after closing the transaction.
As preferably, in order to prevent that the artificial malice of board units is removed, automotive sunshade panel also comprises anti-disassembling mechanism and detaching-proof antenna box 126, anti-disassembling mechanism and antenna 103 are all arranged on detaching-proof antenna box 126 inside, anti-disassembling mechanism is electrically connected with control unit by anti-taking out stitches, and control unit is for determining the disassembly status of board units according to the Anti-dismantling signal of anti-disassembling mechanism transmission.Anti-disassembling mechanism can with the public connection lead 104 of antenna 103, public connection lead 104 is taken out stitches as anti-, also can connect respectively a connection lead 104, no matter that situation, connection lead 104 can be drawn from housing 116 tops, left sides by the metallic channel of sun shield housing 116 inside.
