Public safety pre-warning system based on Internet of Things

Abstract

The invention provides a public safety pre-warning system based on the Internet of Things. The public safety pre-warning system includes a master control module, a video acquisition module, a video decoding module, a storage module, a video coding module, a wireless module and a power module, the master control module is electrically connected with the video decoding module, the storage module, the video coding module, the wireless module and the power module, and the video acquisition module is electrically connected with the video decoding module. The device provided by the invention is simple in structure and convenient to install, multi-channel video acquisition realizes omnibearing monitoring, the storage space is expanded, the problem of insufficient storage space of an existing device is overcome, at the same time, a wireless transmission mode is adopted, and data information of a monitoring site can be rapidly transmitted to a monitoring terminal, thereby realizing rapid and effective safety precaution.

Description

technical field [0001] The invention relates to the field of safety early warning devices, in particular to a public safety early warning system based on the Internet of Things. Background technique [0002] Public safety is an important prerequisite for ensuring the normal life of human beings. However, tragedies caused by terrorist attacks, natural disasters, and man-made accidents are constantly recurring. For this reason, governments of all countries are actively strengthening the research on the prevention of public emergencies and the emergency response system. Among them, the crowd flow early warning system is mainly to analyze the crowd density in public places, and to give early warning when the crowd density is too large, so as to facilitate timely evacuation of the crowd to prevent dangerous accidents. Most of the current safety early warning devices are comprehensive devices, and the camera in the device The monitoring area is too small, and the storage space is ...

Problems solved by technology

Among them, the crowd flow early warning system is mainly to analyze the crowd density in public places, and to give early warning when the crowd density is too large, so as to facilitate timely evacuation of the crowd to prevent dangerous accidents. Most of the current safety early warning devices are comprehensive devices, and the camera in the device The monitoring area is too small, and the storage space is small. For example, the Chinese invention safety warning system with the authorized announcement number CN 203376839U proposes a safety warning system that can be deployed quickly, including crowd warning front-end, fire detection front-end, and face recognition front-end and background monitoring terminal, etc., the system structure is complex
