Digital signage-based emergency evacuation system and method

Abstract

The invention discloses a digital signage-based emergency evacuation system and method. The system comprises a camera system capable of performing real-time monitoring, an image acquisition module used for performing sampling on images of monitoring regions in real time, a human face detection module used for detecting human faces in an image sampling range, a cloud end which detects the repetitive rate of the human faces and performs comparison according to the number of people subjected to statistics and the number of alert people, a digital signage and loudspeaker integrated module used for guiding crowds to be evacuated in order according to an instruction sent by the cloud end, and a PC end used for monitoring a state of each monitoring region in real time and displaying a number-of-people statistics state. According to the system and the method, the people flow of the regions can be effectively monitored in real time, the number of people can be assessed, and the assessment precision is relatively high, so that the safety of the monitoring regions can be ensured.

Description

technical field [0001] The present invention relates to an emergency evacuation system and method based on a digital signage, in particular to an emergency evacuation system and method for counting people by face detection. Background technique [0002] With the development of economy and society, people's daily life is more colorful. In many tourist attractions, stations, shopping malls and other places, crowds often occur, and accidents such as stampede and congestion are especially prone to occur. And there is not yet an effective means to command the flow of people to evacuate in an orderly manner when disasters occur or will occur, so as to alleviate or avoid the occurrence of disasters. The current emergency evacuation systems are all that when a disaster occurs, the alarm is triggered by the corresponding sensing equipment, or the alarm is triggered by human intervention. The command is usually manually shouted through the tweeter to guide the evacuation of the flow ...

AI Technical Summary

Problems solved by technology

The crowd in panic has no time to take care of the command of the commanders, and it may even cause the chaos to deteriorate further. It is difficult to achieve excellent command effects by simply cooperating with the manual command of the loudspeaker.

At the same time, it is difficult to have accurate data to explain by human visual inspection; and human inspection is easy to cause artificial fatigue and lead to negligence

[0003] At present, there is no effective device and method to ensure early warning and timely emergency response when disasters are about to occur; therefore, it is very meaningful to invent and design a set of automatic early warning and replace manual effective command methods
