Video monitoring system based on gravity sensing technology

Abstract

The invention discloses a video monitoring system based on the gravity sensing technology in order to achieve the intelligent control function that the video monitoring system is automatically turned on when taken up and is automatically turned off when put down. The video monitoring system is composed of a master control circuit board and a liquid crystal screen; the master control circuit board is composed of a multimedia master control chip, a gravity sensor, a liquid crystal display screen controller and a WIFI module. When the video monitoring system is taken up by a person, the acceleration value of the video monitoring system can change continuously, and the gravity sensor can correspondingly send out electrical signals continuously and transmit the signals to the multimedia master control chip; the multimedia master control chip is provided with an interrupt triggering controller and video monitoring software, the interrupt triggering controller triggers a hardware interrupt signal according to the electrical signals sent by the gravity sensor, and the video monitoring software reads the interrupt signal and controls the liquid crystal screen to be turned on or turned off. The intelligent control function that the video monitoring system is automatically turned on when taken up and is automatically turned off when put down is achieved, and the practicability and convenience of the video monitoring system are greatly improved.

Description

technical field [0001] The invention relates to a video monitoring system in home security equipment, in particular to a video monitoring system based on gravity sensing technology. Background technique [0002] With the rapid development of home security technology, home security gradually has many new applications. For example, systems such as Baby Monitor enable you to see whether a child has fallen off the bed or kicked the quilt while lying on the bed, which greatly reduces the burden on parents to watch their children at night. The current home video surveillance systems mainly include analog systems and digital systems. [0003] Such as figure 1 , The home video surveillance analog system consists of an analog camera, CVBS (Composite Video Broadcast Signal, composite video broadcast signal) coaxial cable, and a TV. Both the analog camera and the TV are equipped with CVBS jacks as standard, and the two are connected through a CVBS coaxial cable; the video signal sho...
