Description

A camera device with driving recording function

technical field

The utility model relates to the field of automobile safety, in particular to a camera device with a driving recording function.

Background technique

At present, with the development of automobile active safety technology, more and more cars are equipped with front radar or front camera devices. At the same time, cars must also be equipped with driving recorders, and front cameras and driving recorders are basically Similarly, if the front camera and the driving recorder are assembled at the same time, it will cause a waste of resources; if the front camera replaces the function of the driving recorder, a large storage space will be required, and the relevant information in front of the vehicle will be recorded in real time. When the storage space reaches When the upper limit is set, the earlier records will be overwritten, and the recorded information will not be distinguished, and there may be a risk of valid information being overwritten and lost. Chinese Patent Publication No. CN202650093U, published on January 2, 2013, a utility model patent titled "Video Monitoring Instrument for Automobiles" discloses a video monitoring instrument for automobiles, including a front camera, a rear camera, and an in-vehicle camera. , display, main control board, storage device and keyboard input device monitoring system; the signal of the camera is connected to the main control board through wireless or cable, and the video signal collected by the camera is synthesized by DSP, and then compared with time and other vehicle conditions The image information is formed after the information is superimposed; the image information is saved to the storage device in one way according to the configuration, and is output to the display in real time in the other way. In addition to the general real-time monitoring function, the instrument also has the functions of image synthesis, recording and playback. The disadvantage is that this video monitoring instrument still does not solve the problem that the stored data may be lost, and it still cannot be used as a driving recorder.

Utility model content

The purpose of this utility model is to overcome the shortcoming that the front camera replaces the driving recorder in the prior art to record insufficient information, and the effective information is easily covered, and provides a camera device with a driving recording function, and the effective information of the device can be completely record, and the storage space is small.

The purpose of this utility model is to be realized through the following technical solutions:

A camera device with a driving recording function, comprising an MCU, a camera, a first memory, a second memory and a third memory, the MCU is simultaneously connected to the camera, the first memory, the second memory and the third memory, and the camera is connected to the first memory respectively , the second memory and the third memory are connected, and the camera is arranged at the front end of the car. The first memory is used to record the image data of the car in an emergency dangerous situation such as a collision accident, the second memory is used to record the image data of the car in a general dangerous situation such as an accident during driving, and the third memory is used to record normal driving Image data in process. Among them, the image data in the first memory cannot be overwritten, and can only be read; the image data in the second memory cannot be overwritten, and the user can manually generate this data or automatically generate it after a certain period of time; the third memory image data can be overwritten. Because the storage space in the second memory and the third memory can be reused, the storage space is greatly reduced, the cost is low, and important image data will not be lost, completing the function of the driving recorder.

As a preferred solution, the camera device with the driving recording function further includes an airbag electronic control unit, and the airbag electronic control unit is connected to the first memory. When the automobile collides, the airbag electronic control unit controls the opening of the airbag and at the same time sends a signal to the first memory to make the first memory work and record image data.

As a preferred solution, the camera device with a driving record function further includes a driving recorder, and the driving recorder is connected to the first memory. The driving recorder can work alone or together with the camera, which improves the stability of the whole device. When the driving recorder or the camera fails, the whole device can still work to achieve the purpose of recording images.

The beneficial effect of the utility model is that the camera device with the driving recording function can effectively record driving information, complete the driving recording function, and at the same time require less storage space and save costs.

Among them: 1. MCU, 2. First memory, 3. Second memory, 4. Third memory, 5. Camera, 6. Airbag electronic control unit.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Embodiment 1: A kind of camera device with driving recording function, its circuit principle connection diagram as shown in Figure 1, including MCU1, camera 5, first memory 2, second memory 3, third memory 4, airbag electronic control Unit 6, the MCU is connected to the camera, the first memory, the second memory and the third memory at the same time, the camera is connected to the first memory, the second memory and the third memory respectively, and the camera is arranged at the front end of the car. The airbag electronic control unit and the driving recorder are simultaneously connected to the first memory.

The first memory is used to record the image data of the car in an emergency dangerous situation such as a collision accident, the second memory is used to record the image data of the car in a general dangerous situation such as an accident during driving, and the third memory is used to record normal driving Image data in process. Wherein, when the automobile collides with an accident, the airbag electronic control unit controls the opening of the airbag, and at the same time sends a signal to the first memory to make the first memory work and record image data, and the image data in the first memory cannot be overwritten. Can be read; the image data in the second memory cannot be overwritten, the user can generate this data manually or automatically after a certain period of time; the image data in the third memory can be overwritten. Because the storage space in the second memory and the third memory can be reused, the storage space is greatly reduced, the cost is low, and important image data will not be lost, completing the function of the driving recorder.

Embodiment 2: A camera device with driving recording function, its principle and implementation method are the same as in Embodiment 1, the difference is that it also includes a driving recorder, which is connected to the first memory. The driving recorder can work alone or together with the camera, which improves the stability of the whole device. When the driving recorder or the camera fails, the whole device can still work to achieve the purpose of recording images.
