Intelligent Video Analysis Technology for Tobacco Factory Security Management

1, Based on the statistics of the number of duty monitoring

In the cigarette stacking area where finished products are stocked, cigarettes have been lost many times, resulting in greater losses. Although there are many people monitoring each surveillance area, there is no guarantee whether this person is in the post, and the specific access conditions are not known.

In view of the above, one HD camera can be installed in each surveillance area, and intelligent video analysis algorithms can be used to count the number of people. Using IPC's dual-streaming function, the main stream is 1080P resolution for high-definition video storage, and the sub-stream is CIF resolution for smart analysis of people statistics. The number of people in the detection area is updated in real time and alarm linkage is performed. At the same time, an event tag can be inserted in the video. On-duty personnel can perform real-time processing, contact relevant leaders, and provide prompt warning to off-site personnel. For subsequent searches, only relevant events need to be searched to see when relevant personnel have been released. As for high-definition video playback, combined with the digital PTZ function, you can clearly see whether this person is a legitimate duty officer.

2. Disable area monitoring based on legacy testing

For safe production, there are more areas in the plant area that are forbidden, such as in the silk workshops, roll-packing workshops, and stacking of tobacco and cigarettes. For traditional monitoring, only specialized people can be used to supervise in designated areas, which requires a lot of labor costs.

After adopting network video surveillance, intelligent video analysis technology can be used to enable the legacy detection function to install multiple network cameras in the corresponding wire making and wrapping workshops, demarcate disabled areas, enable legacy detection functions, and prohibit stacking according to actual conditions. The object size is set by corresponding parameters, and various alarm actions are performed in combination with the event settings of Ruijie RVS. For example, the alarm video and information pop up in the sub-control room to remind the on-duty personnel to handle, or use the two-way voice function of the camera as an alarm reminder .

3, based on the line of the conveyor belt fault detection

In order to ensure smooth production, when it fails, it can quickly respond to and process it, requiring all-round monitoring of production equipment. New requirements have been put forward for related production equipment such as wiremaking workshops, roll-packing workshops and warehouses. As industrial production, when a certain part of the production line fails, it will directly affect the output of the entire production line.

The use of video analysis technology to detect production equipment, when the equipment fails, timely alarm. For the conveyor belt monitoring, when the conveyor belt fails, the main performance is that the running speed is too slow or even stops, or the operation is reversed. According to the special equipment fault manifestation, the double crossover analysis function is adopted at the beginning of the conveyor belt and the result place. A detection line is set separately. When the detection target passes through the two detection lines within a specified time, the system determines that it is normal. When this time is exceeded, it is deemed to be a failure of the conveyor belt and an alarm is issued. The retrograde function is used to set the middle of the conveyor belt. A detection line is set. When the detection target moves in the reverse direction, it is judged as a device failure and alarm linkage is performed. In combination with Ruijie RVS's event settings, the alarm data will be pushed to the maintenance personnel's terminal to make an alarm and an alarm video will be popped up for the maintenance personnel to make a video review and respond as soon as possible.
