Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail;
The drive recorder that Fig. 1 is the present invention connects the structure block diagram with WiFi communication module;
Fig. 2 be the present invention drive recorder connect computer structure block diagram;
Fig. 3 is the structure block diagram of the time of the drive recorder shooting digital and electronic clock device of the present invention.
Embodiment
For the present invention is realized technique means, creation characteristic, reach object and effect is easy to understand, below in conjunction with embodiment, set forth the present invention further.
See Fig. 1 to Fig. 3, the present invention be to provide a kind of can the drive recorder of time that quick and precisely obtains promptly and accurately, it comprises CPU processor, sound unit, random access memory ram, SD remembers card, display unit (indicating meter) and battery or electric capacity unit, it also comprises one for connecting the WiFi communication module of external mobile device acquisition mobile equipment time, one for connect computer obtain the network time computer flash memory equipment NAND and for obtaining the shooting unit of digital and electronic clock device current time, this shooting unit is connected with CMOS sense and surveys camera lens, by CMOS sense survey camera lens obtain highway overhead on the shooting sectional drawing of digital and electronic clock device, thus obtain the current time of digital and electronic clock device, described sound unit, random access memory ram, SD remembers card, display unit, WiFi communication module, computer flash memory equipment NAND and shooting unit and is all connected with CPU processor, described computer flash memory equipment NAND is also connected with USB interface, is connected with computer by USB interface.
The acquisition of the present invention above-mentioned time method is as follows:
(1) the network time is obtained by WiFi communication module. see Fig. 1, when using the mobile equipment having with WiFi communication module, such as cell phone, mobile phone is because connecting public network, and its time has height exactness. With WiFi function drive recorder, major part is only connected with mobile phone, directly do not surf the Net, so can when being connected with intelligent mobile phone, agreement communication way is utilized by WiFi communication module, directly obtain mobile phone time just can, using this current time of obtaining as the current time of drive recorder. As long as within this action one day at most once, because drive recorder has built-in RTC and time maintenance device, such as electric capacity or battery.
(2) connect computer by USB interface and obtain the network time. See Fig. 2 computer because often surfing the Net, its time has height exactness. Drive recorder is connected with computer by USB interface, now the internal memory of drive recorder is such as computer flash memory equipment NAND, it can be a disc driver for computer, a built-in automatic program execution can be placed in this computer flash memory equipment, while being connected with computer, then program when can automatically perform pair. As long as within this action one day at most once, because having RTC and time maintenance device in drive recorder, such as electric capacity or battery. Drive recorder connects computer obtain the computer current network time in real time by arranging USB interface, using this current time of obtaining as the current time of drive recorder.
(3) camera unit is utilized to obtain the current time of the digital and electronic clock device that overhead place is arranged on road. See Fig. 3, when drive recorder utilize camera unit by CMOS sense survey camera lens scan highway overhead place digital and electronic clock device is installed time, drive recorder utilizes camera unit to survey, by CMOS sense, the image that camera lens obtains digital and electronic clock device current time, the image of recording is analyzed, cut the time of the admission city on the way digital and electronic clock device of eminence erection, using the current time that obtains as the current time of drive recorder.
Digital and electronic clock device on the way eminence can be set up in general city at present, and because of often maintained, its time has height exactness. All drive recorders, all there is camera function, can being analyzed by the image of recording, when drive recorder travels on road, digital and electronic clock device on the way eminence can be set up in a lot of city, its display mode is all hh:mm, such as 12:34 table 12 30 minutes, if can this image digital of identification when doing real-time pair, owing to major part clock device is only shown to point, so pair time the predeterminable one-tenth 30 of part that is worth in the second of time, be also can by the time error control of drive recorder within 30 seconds. As long as within this action one day at most once, because drive recorder has built-in RTC and time maintenance device, such as electric capacity or battery.
The present invention utilizes WiFi communication module, computer flash memory equipment NAND and camera unit to be combined in drive recorder, current correct time is obtained in real time by three kinds of modes, when the accident that avoids occurs, the description Time Inconsistency situation of traffic injury time point and incident party concerned occurs, ensure that the accuracy of acquisition time, avoid the defect of manual mode regulating time, it is simple and efficient, accuracy height, is worth of widely use.
More than show and describe the ultimate principle of the present invention and the advantage of main characteristic sum the present invention. The technician of the industry should understand; the present invention is not restricted to the described embodiments; the principle that the present invention is just described described in above-described embodiment and specification sheets; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.
