Road test belongs to class test subject under battle conditions, and it is different from theory examination carries out indoor, and road test needs the practical operation test of an examination highway section enterprising driving driving out of doors.Due to vehicle in the examination process, in continuous movement, unless examination control center arranges the invigilator personnel with outside car, be difficult to reference personnel's examination process is managed, therefore, this has brought a lot of troubles to examination again.
The utility model content
The purpose of this utility model is to provide a kind of Examination instrument, mainly solves the road test existed in prior art and manages inconvenient problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Examination instrument, comprise the shell that is provided with keyboard, and be arranged at the sound circuit plate of this enclosure; Be provided with central processing unit on described sound circuit plate, the power interface, loudspeaker and the speech chip that with this central processing unit, are connected respectively, and described keyboard also is connected with this central processing unit.This power interface can be complementary with the automobile cigarette lighter jack, the USB interface coupling that also can carry with automobile, thus it is convenient that automobile is used.
Further, also be provided with earphone socket on described sound circuit plate.
In order to guarantee voltage stabilization, prevent that voltage jump from causing damage of internal device, be provided with the DCDC voltage stabilizer between described power interface and central processing unit.
The audio of playing in order to ensure loudspeaker, also be provided with power amplifier between described loudspeaker and central processing unit.
In order to realize the transmitting-receiving of infrared signal, on described sound circuit plate, also be provided with the infrared receiving terminal be connected with described central processing unit.
Again further, also be provided with the Micro SD deck be connected with described central processing unit on described sound circuit plate.
Further, also be provided with the GPS orientator be connected with described central processing unit on described sound circuit plate.
For the ease of operation with improve aesthetics, described keyboard is matrix by button and arranges and form.
In addition, for controlling cost, described shell and button are made by plastics.
And, also be provided with the FM transmitter be connected with central processing unit on described sound circuit plate, thereby realize automobile broadcast.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model all concentrates on all components and parts on same circuit board, has both realized the centralization installation and management of components and parts, has realized the miniaturization of whole instrument, and the encapsulation for circuit board provides convenience again.
(2) the utility model is provided with Micro SD deck, can use Micro SD card to carry out the information storage, and maximum can be supported the storage card of 16G, for the information recording in the road test process provides sufficient space.
(3) the utility model is provided with keyboard, can control at any time the duty of Examination instrument by operation keyboard, as the audio frequency broadcasting of controlling loudspeaker, the transmitting-receiving of infrared information, location of GPS etc., very convenient.
(4) the utility model has guaranteed the stability of power supply by the DCDC voltage stabilizer, has improved stability and the reliability of whole instrument, and its practical value is greatly promoted.
(5) the utility model is cheap, is applicable to very much large-scale promotion and uses.
The accompanying drawing explanation
Fig. 1 is system chart of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, Examination instrument, mainly comprise shell and sound circuit plate, shell is plastic casing, is provided with one on it and is keyboard and a plurality of interface that matrix is arranged, and this keyboard is formed by a plurality of key arrangement, and button also is made of plastics, so can improve feel.
Each function element is installed on the sound circuit plate, and wherein, central processing unit is core devices, for the treatment of various information, and controls the work of other devices.Speech chip is connected with central processing unit, and for identifying each voice document, for Examination instrument provides the voice support function, as the identification of voice document form, broadcasting of voice document etc., the utility model adopts speech chip WAV502 chip to complete its function.Loudspeaker are connected with central processing unit by power amplifier, after the voice document that speech chip identification is supported, to control loudspeaker by central processing unit and play corresponding file, power amplifier is regulated the sound of playing, guarantee the tonequality of playing, to improve result of broadcast.Present technique adopts external power supply; the power interface be connected with central processing unit only is installed on the sound circuit plate; for guaranteeing the stability of voltage; be provided with the DCDC voltage stabilizer between power interface and central processing unit; after the external power source access; by the adjusting of DCDC voltage stabilizer, make each element on the sound circuit plate all obtain stable voltage, thereby element is played a good protection.
In addition, also be provided with infrared receiving terminal, GPS orientator, earphone socket and Micro SD deck in the present embodiment, wherein, the infrared receiving terminal be connected with central processing unit is mainly used in receiving infrared signal, thereby make road test easily realize infrared invigilator, greatly reduce invigilator personnel's human cost, alleviated invigilator personnel's workload and work difficulty.The GPS orientator is mainly used in vehicle location is positioned, but earphone socket lug machine, librarian use for reference, and the setting of Micro SD deck makes Examination instrument realize large capacity storage.After Micro SD card inserts Micro SD deck, various information all can be stored, and the various information such as voice document, infrared information, GPS locating information all can be stored, for follow-up examination of taking an examination control center provides reliable resource.
The utility model is multiple functional, cheap, easy to operate, is applicable to very much large-scale promotion and uses.
Above embodiment is only a kind of preferred embodiment of the present utility model, and not, to the restriction of the utility model protection domain, the non-creativeness carried out as long as adopt design concept of the present utility model conversion, all belong to protection domain of the present utility model.
