Description

A kind of orientable drive recorder

Technical field

This utility model relates to drive recorder technical field, especially one can position drive recorder.

Background technology

From in general, its technological layer of monitor product of current numerous domestic still locates the primary stage, not yet Occur that excellent product truly, major part product fail to solve the big source of vehicle accident three well and surpass Speed, overload, fatigue driving.The speed limit warning function being used widely at present solves to a great extent Hypervelocity of having determined problem, but the overload problems of overload problems, particularly passenger stock, fail to obtain well Solve, it addition, the monitoring of Human Physiology fatigue phenomenon, warning means are more short of, can only be from driving continuously Time aspect keeps a record and time-out is reported to the police.Additionally, vehicle fire-fighting could not be solved very well, once hand over Vehicle fire in interpreter's event, monitor certainly will thoroughly destroy, and chip record data can not be extracted.Additionally, note Record instrument to the critical failure information at the position such as automobile engine, brake system can not alarm in time, prevent in not So, processing in communication and be the most only to provide sub-fraction superficial layer analyzing data, the accident before real collision is returned Put and can not get effective, directly perceived, real reproduction etc..All above-mentioned aspects are all to there is more having much room for improvement With the place solved.

The traditional function of monitor is the running data of record automobile and reminds driver safety driving, and it is not only Can effectively prevent the generation of road traffic accident, and carry out accident analysis for law enfrocement official and process carries Science, loyal initial data are supplied.

But along with the raising day by day of customer demand, the most large-scale passenger company to mobile monitoring ability, Improve scheduling to greatest extent and operating capability is had higher requirement；Along with day by day skyrocketing of international oil price, To fuel-economizing, fuel-efficient have higher requirement；Along with the bus extensive application in automotive electronics, to data Collection and exchange have higher requirement.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model proposes a kind of orientable drive recorder, its Purpose is to realize bus location by drive recorder and can transmit the related data of automobile to remotely controlling End.

In order to solve above-mentioned technical problem, the basic technical scheme that the utility model proposes is: one can be determined The drive recorder of position, including monitor body and the location that is connected by serial communication with this monitor body Module；

Wherein, described monitor body includes MCU module, and this MCU module connects to be had for realizing nothing Line data transmit the GPRS communication module with voice communication, for gathering the data acquisition module of image and image Block, for realizing the transmitter receiver module of voice communication, for storing the memory module of data, for showing boundary The display module in face, for detecting the acceleration sensor module of translational acceleration, for debugging function and expansion The RS232 module of exhibition connection and power module；

Wherein, described locating module includes that a single-chip microcomputer, described single-chip microcomputer are connected to the north for location Bucket module and GPS module, for being connected with automobile bus with the CAN mould of acquisition car steering signal Block, for preventing the power-down protection circuit of power down, switching value acquisition module.

Further, described MCU module model is TCC8902.

Further, described single-chip microcomputer model is STM32F103RBT6.

Further, described MCU module connects alarm modules, when CAN module detects automobile When speed is beyond setting value, MCU module will control alarm modules and send alarm.

The beneficial effects of the utility model are:

The technical solution of the utility model passes through Design Orientation module, it is achieved that led by drive recorder The function of boat；It addition, the data of described automobile can be obtained by CAN module, and finally lead to Cross GPRS module and be sent to long-range terminal, it is achieved car data monitors.

Detailed description of the invention

Below with reference to accompanying drawing 1 to accompanying drawing 3, this utility model is described further, but should not come with this Limit protection domain of the present utility model.

This utility model one can position drive recorder, including housing (this housing is not shown), at housing Inside it is provided with monitor body 100 and the locating module being connected with this monitor body 100 by serial communication 200；This monitor body 100 and locating module 200 are parts independently, and it is by serial ports even Connect, different locating modules 200 and recorder module 100 can be changed according to demand, it is achieved different merits Can, improve autgmentability, the conventional serial ports in specifically this serial ports is field.

Concrete, described monitor body 100 includes MCU module 101, and this MCU module 101 connects Have the GPRS communication module 102 for realizing wireless data transmission and voice communication, for gather image and The data acquisition module 103 of image, for realizing the transmitter receiver module 104 of voice communication, for storing number According to memory module 105, for the display module 106 of display interface, for detecting adding of translational acceleration Acceleration sensor module 107, for debug function and extension connect RS232 module 108 and power supply mould Block 109.

Wherein, the model of MCU module 101 is TCC8902, have employed multimedia application processor, main Frequency is more than 600MHz.GPRS communication module 102 is the GSM/GPRS module of two frequencies, it is possible to realize not Communication with frequency range.Data acquisition module 103 is photographic head, and this photographic head is to expose housing, to driving feelings Condition carries out storage of photographing or take pictures, and the data obtained will be stored in memory module 105 by MCU module 101 In.The mutual of user and monitor body 100 is realized by transmitter receiver module 104.It addition, display module 106 is LCD display, for operation display interface and photographic picture.Wherein, acceleration sensor module Under the effect of 107, automobile acceleration situation in the process of moving, convenient monitoring detected.RS232 module Purpose be improve drive recorder autgmentability, can be according to different use demands, by this RS232 Module 108 is connected with MCU module 101, increases the function of drive recorder.
