Through flame monitoring camera, smog surveillance camera, cable conductor surveillance camera, three kinds of cameras come the interior real-time environment of surveillance cabinet to whether independently discernment has phenomenons such as firelight, smog, electric leakage, the rethread wireless communication module feeds back the information that the camera was gathered to video display equipment on, when the alarm situation appears, still can send the SMS to relevant personnel's cell-phone on, make relevant personnel in time maintain the inspection.
The monitoring method comprises the following steps:
firstly, shooting a video in a ring main unit by a camera;
step two, the flame camera automatically identifies whether flame conditions exist in the video;
step three, the smoke camera automatically identifies whether smoke exists in the video;
the cable line camera automatically identifies whether a cable line is exposed in the video, and the video shot before the inside of the camera is compared to identify whether different cable positions appear or not and find whether the cable line is exposed or not;
fifthly, transmitting the video signals shot by the three cameras to video display equipment through a wireless communication module;
in the monitoring room, related monitoring personnel observe videos on the video display equipment, check whether abnormal conditions exist, operate the cameras through a mouse and other modes to stretch, zoom, move the monitoring range and the like, and the operation signals are also sent to each camera through the wireless communication module;
and step seven, when an alarm signal is found in the video or a problem is found in the video in the monitoring room, timely sending information to a mobile phone of a maintenance manager on duty on the day, and allowing related personnel to go forward for maintenance.
And the second step, the third step and the fourth step are all carried out judgment and identification at the same time, and 24-hour uninterrupted shooting and identification are carried out.
Advantageous effects
Compared with the prior art, the invention has the beneficial effects that: a large amount of field wiring of original monitoring is removed, the trouble of a special network wired mode is not needed, the problem of high cost of laying optical fiber networking is greatly reduced, the intelligent video monitoring system can automatically identify abnormal conditions in the collected videos, alarms can be sent out in a fastest and optimal mode, effective information can be provided, safety personnel can be effectively assisted to deal with crises, and the phenomena of false alarm and false alarm omission are reduced to the maximum extent.
