Abstract

The present invention discloses an antitheft monitoring and recording system for automobiles. The system monitors images around automobiles through a video camera and does not stop storing taken images in a memory of an image memorizer until an alarm mark is distinguished to be '1'. When an automobile is attracted by foreign objects, an alarm is activated and sends out alarm sound, and the alarm mark is automatically set to be '1'. Meanwhile, the image memorizer is stopped when the memory area block of the time is fully stored and does not continue alternate storage. Meanwhile, the owner of the automobile is informed at real time through a mobile communication network, and the state of image monitoring is returned. In this way, the owner of the automobile can query the condition of the automobile through a mobile communication system at any time.

Description

Theftproof monitoring secret recording system for car

Technical field

The present invention relates to a kind of theftproof monitoring secret recording system for car, but refer to the process that a kind of complete documentation automobile is harassed by foreign object especially, and pass through mobile communication network real-time informing car owner's monitoring secret recording system.

Background technology

Existing car alarm in design, when receiving automobile abnormal condition (collision) signal with a sensor, can send the noise of high-decibel by alert driver circuitorder siren horn, frighten the invader away, the defective of this scheme is, this car owner can not in time reach the spot, and therefore, can't learn the situation that invader and automobile are harassed.

Based on this, the inventor concentrates on studies and cooperates the utilization of up-to-date science and technology, but designs the process that a complete documentation automobile is harassed by foreign object, and the theftproof monitoring secret recording system for car by mobile communication network real-time informing car owner.

Summary of the invention

Main purpose of the present invention is, an available less storage memory size is provided, the be attacked monitoring secret recording system of process of omnidistance record automobile.

Another object of the present invention provides a system, can make the car owner of this automobile inquire about condition of the vehicle with mobile communcations system at any time, or acquisition motor vehicle environment image.

Another purpose of the present invention provides just like automobile and is stolen or towing, can inquire about the system of this condition of the vehicle by mobile communcations system.

For realizing this goal of the invention, technical scheme of the present invention is, by be located on the automobile pick up camera constantly will around image alternately be stored in the memory block of image holder, differentiated for stopping for the moment until alarming sign, when this automobile is subjected to the foreign object harassment, promptly activate siren horn and send caution sound, and the automatic setting alarming sign is one, at this moment, this image holder only stores full promptly stopping afterwards with memory block at that time, no longer continues alternately to store, simultaneously, by mobile communication network real-time informing car owner, and return monitoring image state.

The invention has the beneficial effects as follows, available little memory capacity, the process that omnidistance record automobile is harassed by foreign object is informed the car owner in real time by mobile communication network; Simultaneously, the car owner also can inquire about this condition of the vehicle with communication receiving/transmission device (GSM communication handset, GPRS or 3G communication handset) at any time, or image around the acquisition; If automobile is stolen or towing, the car owner can inquire about condition of the vehicle by mobile communcations system.

Below in conjunction with the drawings and specific embodiments, the invention will be further described.

Description of drawings

Fig. 1 is a system logic block diagram of the present invention;

Fig. 2 is the use scheme drawing of system of the present invention;

Fig. 3 and Fig. 4 are the control flow charts of system of the present invention.

The specific embodiment

In Fig. 1 and Fig. 2, system of the present invention comprises two pick up cameras 1,1 ', one image holder hold concurrently a logic controller 2 and a communication dialer 3, and wherein pick up camera 1,1 ' is located on the relative position of automobile 4 bodies, so that the image around the monitoring automobile 4.

The image holder logic controller 2 of holding concurrently, in order to store the logic control from pick up camera 1,1 ' picked image data and total system, as setting alarming sign etc., its image holder includes two memory blocks, alternately to store image.

Communication dialer 3 is that the alarming sign at logic controller is automatically made for the moment, the image data that access is harassed by foreign object is sent, and notified the car owner these automobile 4 situations, and this communication dialer 3 is a mobile communcations system (GSM) dialers in the present embodiment.

Fig. 3 and Fig. 4, it is system of the present invention control flow chart, in step 30, each pick up camera begins to capture the motor vehicle environment image data, in step 31, first memory block of image holder promptly begins to store from pick up camera picked image data, then then, execution in step 32, logic controller can check whether the space of first memory block is full;

If less than, get back to step 31, otherwise, execution in step 33, this logic controller differentiates whether alarming sign (alarm flag) is one;

If alarming sign is one, stop operation, otherwise, execution in step 34, second memory block of this image holder begins to store institute's picked image data, and following step 35 checks whether the space of second memory block is full;

If less than, be back to step 34, otherwise, execution in step 36, whether differentiate alarming sign is one;

If alarming sign is one, stop operation, otherwise, be back to step 31 and continue video data storing.

When this automobile is harassed by foreign object, enter step 37, promptly activate siren horn and send caution sound, simultaneously in step 38, the automatic setting alarming sign is one, at this moment, the memory block that this image holder only will be at that time stores and fullly promptly stops, and no longer continues alternately to store, simultaneously, enter step 39, notify the car owner this condition of the vehicle, and return monitoring image state by GSM (GSM) communication network.

Like this, this car owner can inquire about the situation of this automobile 4 at any time with mobile communcations system, and can not learn the defective of invader and condition of the vehicle.

In addition, by the present invention design, also can be stolen or during towing, utilize this mobile communcations system to inquire about this automobile 4 situations at this automobile 4.

In sum, by particular design of the present invention, have as following plurality of advantages:

1. can use the little memory capacity, the process that omnidistance record automobile is harassed by foreign object.

2. can inform the car owner in real time by mobile communication network.

3. the car owner can inquire about this condition of the vehicle with communication receiving/transmission device (GSM communication handset, GPRS or 3G communication handset) at any time, or image around the acquisition.

4. if automobile is stolen or towing, the car owner can inquire about condition of the vehicle by mobile communcations system.

The above only is the specific embodiment of the best of the present invention, and feature of the present invention is not limited thereto, and the those skilled in the art in any present technique field are in the field of the invention, and variation of making easily or modification all are included in the claim of the present invention.
