Description
Technical field
The utility model belongs to motor vehicle identity identification field, particularly a kind of on-vehicle terminal device of motor vehicle identity wireless identification.
Background technology
At present, in the inspection of motor vehicle identity legitimacy, such as the identity checks of special car such as police car, taxi, drover's car, usually adopt the remote radio frequency device, it is made up of car-mounted terminal and handheld terminal two parts.Because radio-frequency card does not possess the execution function, the supervisory personnel must check the car plate data of reading earlier when checking vehicles, and the car plate data with vehicle contrast again, just can judge the legitimacy of vehicle.The decipherment distance of remote radio frequency card is 100 meters, be per hour 60 kilometers calculating with normal vehicle operation speed, the supervisory personnel must in seconds make judgement, the supervisory personnel also is not able to do in time to judge one by one often, vehicle has just passed through the checkpoint, particularly the spacing of looking into vehicle when many quilts hour just more is difficult to judge that therefore this mode can not satisfy the demand of non-parking checking.
Summary of the invention
Problem to be solved in the utility model provides a kind of on-vehicle terminal device of motor vehicle identity wireless identification, and this device can reflect the identity of motor vehicle rapidly intuitively.
The technical scheme that addresses the above problem is: the on-vehicle terminal device of the motor vehicle identity wireless identification that is provided has CPU, the storer that links to each other with CPU respectively, RF wireless radiofrequency transport module and amplifying circuit, and the output terminal of this amplifying circuit is connected with status indicator lamp.
The testing vehicle register wireless identification system mainly is made up of handheld terminal two parts that car-mounted terminal and supervisory personnel hold, and the utility model belongs to car-mounted terminal, and handheld terminal and car-mounted terminal carry out the double-direction radio communication by the RF wireless transport module.During inspection, the supervisory personnel sends by handheld terminal and checks signal, car-mounted terminal is connected amplifying circuit through checking, processing after receiving signal, the flicker of driving condition pilot lamp, simultaneously vehicle identity information is dealt into handheld terminal, the supervisory personnel can judge the legitimacy of vehicle by the demonstration of viewed status pilot lamp.
Above-mentioned status indicator lamp can be one or more, can be bulb, light emitting diode or other light source.The status indicator lamp of being made up of a plurality of different color LEDs can be realized the demonstration of different colours.
The amplifying circuit of above-mentioned status indicator lamp can be triode amplifying circuit, controllable silicon amplifying circuit or solid-state relay driving circuit.
Above-mentioned CPU also can connect an alarm switch, this alarm switch can be put in the car, when in case of emergency, when for example being held as a hostage, the driver touches alarm switch, status indicator lamp can glimmer (as redness) according to specific color, and this vehicle is by the checkpoint time, and handheld terminal can receive alerting signal.
Compare with existing technology, the utility model has been owing to adopted status indicator lamp to show, have simply, fast, accurately, characteristics cheaply, can realize non-parking quick check, legal vehicle is not disturbed its cruising, and can tackle illegal vehicle.The utlity model has good wireless communication and recognition function real-time, because designated color and flicker frequency at random, the personation vehicle can't be learnt in advance, even if the installment state pilot lamp is also of no avail voluntarily, therefore can effectively stop to palm off car plate or clone's vehicle, simultaneously also can be as the wireless electron pass.

Fig. 1 is the structure principle chart of an embodiment of the utility model.
Fig. 2 is the circuit diagram of one of the utility model status indicator lamp example.
Fig. 3 is two a circuit diagram of the utility model status indicator lamp example.
Embodiment
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
As shown in Figure 1: the circuit part of the utility model on-vehicle terminal device has a CPU 1 and the RF wireless radiofrequency transport module 2 that links to each other with CPU 1 (model is JN5121).Consider that from the angle that communication security is stable the frequency of utilization of RF wireless radiofrequency transport module is 2.4---12.483GHz (common name 2.4GHz).The modulation system of RF wireless radiofrequency transport module 2 can be DSSS (direct sequence spread spectrum), and the data in its transmission are used the AES cryptographic algorithm of 128-bit through encryption; The communication protocol standard that adopts is IEEE 802.15.4.Storer 3, amplifying circuit 4 and alarm switch 5 are connected with CPU 1, and status indicator lamp 6 links to each other with amplifying circuit 4, and wherein status indicator lamp 6 should be placed on the position of being convenient to see (such as roof).
Fig. 2 has provided an example of the utility model status indicator lamp.Status indicator lamp is made up of the light emitting diode D1 of a plurality of different colors, and they are driven by separately triode G respectively.CPU control IO mouth output low level is amplified electric current through current-limiting resistance R1 and triode G, and D1 is luminous for the driven for emitting lights diode; When IO mouth output high level, triode G ends, and light emitting diode extinguishes.By the requirement of checking signal, can light the light emitting diode of one or several different colours simultaneously, thereby realize desired glow color.
When CPU 1 receives the inspection signal by wireless transport module 2, authenticate by procedure identification, after authentication, CPU controls amplifying circuit 4, make status indicator lamp 6 send the demonstration of designated color and flicker frequency according to program setting or by the requirement of checking signal, or light a plurality of color state pilot lamp and form designated color, or alternately flicker of different colours, the supervisory personnel can judge the legitimacy of vehicle in view of the above.Meanwhile, CPU takes out the vehicle identity information that exists in the storer 3, outwards launches by wireless transport module 2, is sent to supervisory personnel's handheld terminal.
Fig. 3 has provided another example of the utility model status indicator lamp.CPU 1 control IO mouth output low level, process current-limiting resistance R2 makes the output terminal adhesive of solid-state relay K, and D2 is luminous for the driven for emitting lights diode, and when IO mouth output high level, light emitting diode extinguishes.
