Video monitoring system based on gravity sensing technology

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.
