Embodiment Construction

[0025] As shown in the embodiment of Fig. 1, the vehicle-mounted monitoring system of the present invention includes a camera module and a vehicle-mounted terminal, wherein the camera module is connected to the vehicle-mounted terminal through RS-485, and the vehicle-mounted terminal is connected to the central unit through GSM / GPRS.

[0026] As shown in the embodiment of FIG. 2 , the camera module of the present invention includes a camera (lens + image sensor), a digital signal processor (DSP) and a memory. Its working process is: the object is filtered by the lens and sent to the image sensor (sensor) for image acquisition, and sent to the DSP. Then DSP optimizes the digital image signal parameters through a series of complex mathematical algorithms, and stores the processed data in the external memory, or transmits the data to the central unit through GSM / GPRS according to the requirements of the vehicle terminal.

[0027] The following is a brief introduction to each comp...

Abstract

A vehicle monitoring system is prepared as connecting video camera module to vehicle terminal in communication mode through RS-485 interface for up-transmitting partial shot image to central unit through vehicle terminal and mobile communication network, labeling image files being not up-transmitted to central unit and being stored in image storage to be A type of important file by digital signal processor in video camera module and image files being up-transmitted to be B type of important file, allowing newly shot image to cover B type of important file when storage space of image storage is full.

Description

technical field [0001] The invention relates to a monitoring system, more specifically, to a vehicle-mounted monitoring system. Background technique [0002] With the popularity and number of cars increasing, the number of various types of car crimes has increased sharply. Video monitoring equipment for the location of the car, inside and outside the car has emerged as the times require. Users can monitor and manage the location of the car through GPS. Monitor the status inside and outside the car through video. [0003] In the current vehicle monitoring system, one is to use a hard disk video recorder as a storage device, which has a large volume and poor heat dissipation. Moreover, because the low-frequency vibration on a moving vehicle has a great impact on the hard disk, it is easy to damage the hard disk, ranging from data loss to complete damage to the equipment; in addition, the car supplies power instantaneously when starting, and the stability of the current may af...
