Abstract

The utility model discloses a GPS on-board digital video recorder comprising a hard disk storage unit and an output unit used for outputting the information of the hard disk storage unit, as well as a GPS information receiving module, a video and audio information recording unit and an information processing unit, wherein the information processing unit is connected with the GPS information receiving module and the video and audio information recording unit and used for recording the video and audio information and GPS information in a relative manner; and the information processing unit is connected with the hard disk storage unit. The GPS on-board digital video recorder can simultaneously record the video and audio information at a certain moment and the information relating to the current position, speed and the like of vehicles, can be used for synchronously displaying the map information, the speed information and the video and audio information by virtue of the output unit, and simultaneously has strong search function.

Description

GPS vehicle-mounted hard disks video recorder

Technical field

The utility model relates to a kind of multimedia security protection equipment technical field, is specifically related to a kind of GPS vehicle-mounted hard disks video recorder.

Background technology

The development of mass transit system has brought convenience for increasing people, and owing to the easy proximities and the public character of mass transit system, its safety problem is that administrative authority's emphasis will solve and the most scabrous problem always simultaneously.In recent years, the security incident of a series of great common carriages has abroad taken place in succession, the security incident of domestic common carriage also takes place in succession again and again.After entering 21 century, drive recorder, GPS (being GPS) in mass transit system, have been become the strong technical assistant of public transportation administrative authority by sequential use.But existing product all lacks the record of information video/audio the most intuitively.Along with the development of multimedia technology and automotive electronic technology, the vehicle-mounted digital DVR will become the security guard of mass transit system a new generation.

But traditional vehicle-mounted hard disks video recorder can only write down the audiovisual information in a certain moment, can only inquire about corresponding audiovisual information according to temporal information, the characteristic that can not move according to vehicle, relevant informations such as at that time position of reflection vehicle, speed, thereby also just can not realize retrieving audiovisual information by the positional information of vehicle.

Disclose a kind of vehicle-mounted digital DVR in the Chinese patent 200820095087.5, this vehicle-mounted digital DVR comprises signal processing module and output unit; Described vehicle-mounted digital DVR also comprise speed of a motor vehicle sensing module, the converting unit that links to each other with described speed of a motor vehicle sensing module, with the pulse counter module that described converting unit links to each other, described pulse counter module links to each other with described signal processing module respectively with output unit.This vehicle-mounted digital DVR has reduced the volume of vehicle-mounted DVR, convenient production and assembling, and can monitor the speed of the vehicle in travelling; But it only is used for the speed of real-time monitoring vehicle, can not write down relevant informations such as at that time position of the audiovisual information in a certain moment and vehicle, speed simultaneously.

Summary of the invention

The utility model provides the GPS vehicle-mounted hard disks video recorder of relevant informations such as at that time position of a kind of audiovisual information that can write down a certain moment simultaneously and vehicle, speed.

A kind of GPS vehicle-mounted hard disks video recorder, comprise hard-disc storage unit and the output unit that is used to export the hard-disc storage unit information, it is characterized in that, also comprise the GPS information receiving module, the audiovisual information record cell, and connect GPS information receiving module and audiovisual information record cell and be used for information process unit with audiovisual information and GPS associating information record; Described information process unit connects the hard-disc storage unit.

The described information process unit that is used for audiovisual information and GPS associating information record is that the map location that will receive in the audiovisual information of audiovisual information recording unit records and the GPS information receiving module and velocity information are according to time or corresponding the superposeing of map location.

Described GPS vehicle-mounted hard disks video recorder also comprises the retrieval unit that is used to import retrieving information, and described retrieval unit connects the hard-disc storage unit.

Described retrieving information can be in GPS information such as cartographic information, the speed of a motor vehicle, time and the audiovisual information any one or multiple, to meet the different needs.

Described output unit is voice-output unit, demonstration output unit or voice and display synchronization output unit.

The utility model GPS vehicle-mounted hard disks video recorder can write down relevant informations such as at that time position of the audiovisual information in a certain moment and vehicle, speed simultaneously, and can pass through the synchronous displayed map information of output unit, speed information and audiovisual information, also have powerful search function simultaneously.

Description of drawings

Fig. 1 is the structural representation of the utility model GPS vehicle-mounted hard disks video recorder.

Embodiment

Referring to Fig. 1, the utility model GPS vehicle-mounted hard disks video recorder, comprise hard-disc storage unit 4, be used for exporting the output unit of hard-disc storage unit 4 information, GPS information receiving module 3, audiovisual information record cell 1 connects GPS information receiving module 3 and audiovisual information record cell 1 and is used for information process unit 2 with audiovisual information and GPS associating information record, and the retrieval unit 7 that is used to import retrieving information; Information process unit 2 connects hard-disc storage unit 4, and retrieval unit 7 connects hard-disc storage unit 4.

Output unit is voice and display synchronization output unit, is made up of voice-output unit 5 and demonstration output unit 6.
