Vehicle-mounted device for recording running video with GPS orientation time service information
Technical field
The invention belongs in the technical field of video monitoring a kind of video monitoring and the memory storage that relate to.
Background technology
At present, along with improving constantly of people's living standard, automobile progresses into people's family life, while has also been introduced some potential safety hazards easily bringing fast, generation such as traffic hazard, or the robbery of implementing at vehicle, larceny case, accident Claims Resolution evidence is provided provide when being difficult to find the breakthrough point after case takes place sometimes or traffic hazard taking place, and when single steering vehicle, if in the way of travelling, run into unscheduled event, and there is not the eyewitness time on the scene, can't be for the defense proof is provided self, at these situations, invent a kind of device for recording running video of the vehicle-mounted GPS of having orientation time service information, this device is with the GPS time service, location and speed of a motor vehicle Word message are superimposed upon to be stored on the video image and shows, for people's trip of driving provides safety guarantee, and can provide vaild evidence in crucial moment.
The prior art the most close with the present invention is Vehicular video traveling recorder, the number of applying for a patent is respectively 200820048755.9, structured flowchart as shown in Figure 1, this system is by video camera 1, video storage control system 2, memory device 3, monitor 4 is formed, the image that video storage control system 2 is gathered video camera 1 deposits in the memory device 3, and shows output by monitor 4.Video storage control system 2 comprises MCU control module, video synthesis module, Main Processor Unit and power module.This system is if be installed on the automobile, though the video image that travels can be provided, but can't provide scene road section information, recording time information and the speed information of institute's store video images, therefore for the automobile of maneuverability, the simple generation event attribute that provides image information can not fully explain recording of video has reduced confidence level during also for proof.
Summary of the invention
In order to overcome the defective that prior art exists, the object of the present invention is to provide the practical storage of on-board driving video image, time, place, speed information record, specially for a kind of vehicle-mounted on-site supervision device of Automobile Design with GPS location time service function.
The technical problem to be solved in the present invention is: the device for recording running video that a kind of vehicle-mounted GPS of having orientation time service information is provided.
The technical scheme of technical solution problem comprises as shown in Figure 2: multi-functional video storage control system 5, memory device 6, GPS module 7, monitor 8, video camera 9; Wherein, multi-functional video storage control system 5 comprises GIS (geography information software) module, character laminating module, image Compression module, image storage control module.The video output of video camera 9 links to each other with multi-functional video storage control system 5 by the normal video interface, the signal output of GPS module 7 is carried out communication with multi-functional video storage control system 5 by serial ports and is connected, image one tunnel after multi-functional video storage control system 5 will be handled transfers the normal video image to and is connected with monitor 8, and another road is connected with the input end of memory device 6.
The principle of work explanation: this system is powered by the 12V power supply in the car, also can be powered by battery when automobile is not worked.GIS in the multi-functional video storage control system 5 (geography information software) module, with the gps data information decoding that receives is street information, the character laminating module is superimposed upon timecode information, speed information, the street information literal that resolves on the video image, and image compression module is compressed storage with processed video and shown.Come storage is controlled by three switches on the multi-functional video storage control system 5, first switch control power supply, second switch control begins or stops video storage, the stack of the 3rd switch control whether carrying out Word message.When three switches all during gating, multi-functional video storage control system 5 is carried out communication with GPS module 7 by serial ports, the location and time data that GPS module 7 is provided are by the GIS software decode on the multi-functional video storage control system 5, then specifying information are superimposed upon on the video image that video camera 9 gathers by laminating module.Image one tunnel after the stack is stored on the memory device 6, and another road is shown by monitor 8 by compressing the back.
Good effect of the present invention: the present invention combines gps data and vehicle-mounted real time monitoring apparatus, can realize integrating monitoring, speed of a motor vehicle monitoring, location, antitheftly robs, proof, the multi-functional on-vehicle safety system of time service.

Embodiment
The present invention implements by structured flowchart shown in Figure 2, comprises five parts: multi-functional video storage control system 5, memory device 6, GPS module 7, monitor 8, video camera 9.Wherein video camera 9 adopts simulation visible light camera, the PowerPC MPC8247 that multi-functional video storage control system 5 adopts motorola inc to produce is the integrated circuit board of acp chip, memory device 6 adopts hard disk or SD card, GPS module 7 adopts Vasco da Gama G-mouse GPS receiver module SG-959, and monitor 8 adopts small-sized LCD.
The video output of video camera 9 links to each other with the interface chip of multi-functional video storage control system 5 by the normal video interface, the output of the signal of GPS module 7 and multi-functional video storage control system 5 are connected by serial communication, image one tunnel after multi-functional video storage control system 5 will be handled transfers the normal video image to and is connected with monitor 8, and another road is connected with the input end of memory device 6.Power supply is powered by the 12V power supply in the car, also can be powered by battery when automobile is not worked.Come storage is controlled by three switches on the multi-functional video storage control system 5, first switch control power supply, second switch control begins or stops video storage, the stack of the 3rd switch control whether carrying out Word message.When three switches all during gating, multi-functional video storage control system 5 is carried out serial communication with GPS module 7, the location and time data that GPS module 7 is provided are by the GIS software decode on the multi-functional video storage control system 5, then specifying information are superimposed upon on the video image that video camera 9 gathers by laminating module.Image one tunnel after the stack is stored on the memory device 6, and another road is shown by monitor 8 by compressing the back.
