Method and circuit for restarting DVR video monitoring system in case of system halt

Abstract

The invention discloses a dead halt restart method and a realizing circuit for a DVR video monitoring system. The dead halt restart method for the DVR video monitoring system includes the following steps: the DVR video monitoring program in running process controls the CPU of a host computer to send periodical pulses to the circuit for realizing the dead halt restart continuously; the circuit for realizing the dead halt restart monitors whether the periodical pulses stop or not; if no, the DVR video monitoring program continues to run; if yes, the reset jumper of the host computer is communicated with a direct current power supply by the circuit for realizing the dead halt restart, and the host computer and the DVR video monitoring program are restarted. With the method and the realizing circuit of the invention adopted, when the computer corrupts or the DVR video monitoring program stops running and the video is interrupted owing to the accidental interference on video monitoring spots, the host computer and the DVR video monitoring program can be restarted quickly, the video is basically kept continuously, comparatively complete video data are stored for the video monitoring spots and hidden dangers on the video monitoring spots are eliminated.

Description

[technical field] [0001] The invention relates to the technical field of video monitoring, in particular to a method for restarting a DVR video monitoring system after a crash and an implementation circuit. [Background technique] [0002] The video surveillance system is mainly composed of four parts: front-end camera part, transmission part, control part, display and recording. The system enables managers to observe and record all personnel activities in the front-end protection area in the control room, and provides dynamic image information for the security system. [0003] With the rapid development of modern computer technology, multimedia technology, network technology and digital image compression technology, the DVR digital monitoring system is a multimedia monitoring system with a computer as the core, and the management right is handed over to the computer. If a certain number of cameras are installed in a certain place, the personnel activities in each location i...

Problems solved by technology

However, the video surveillance site often causes the computer to crash or the DVR video surveillance program to stop running due to some uncertainties and unexpected interference, resulting in interruption of video recording. There is no real evidence for the site situation at this time, leaving a safety hazard for the monitoring site

For this unexpected crash situation, the industry has no effective technical measures
