1. Overall Overview

In recent years, with the influx of a large number of migrants, the urban population has shown characteristics such as a large base, high mobility, scattered living locations, and high difficulty in control. As a result, various types of public security, criminal cases, and other social problems have also shown an upward trend year by year, bringing huge tests and challenges to the people's livelihood, urban comprehensive governance, and public security "fighting, preventing, managing, and controlling". At the same time, the demand for new types of cases such as X investigation and XX at the community level has become increasingly urgent. Therefore, it is urgent to build an intelligent and three-dimensional community safety prevention and control system to improve the level of community safety governance and enhance the comprehensive management capacity of the city.

The "Intelligent Community Security System" follows the design concept of "unified planning, unified standards, unified platforms, and unified management". Through video surveillance, micro checkpoints, facial access control, and various IoT sensing devices within the community, it achieves comprehensive perception of community data and events, and fully utilizes new technologies such as big data, artificial intelligence, and the Internet of Things to build an "Intelligent Security Community System" with big data intelligent applications as the core. It has formed a three-dimensional community prevention and control system with the joint efforts of public security, comprehensive management, streets, and property management, effectively enhancing the management capabilities of special groups, key concerns, involved persons, X, etc., continuously improving the predictive and early warning capabilities, precise strike capabilities, and dynamic management capabilities of government agencies such as public security and comprehensive management, and enhancing the capabilities of public security and comprehensive management. Intelligent level of community prevention and control, improving residents' living happiness index.

The real estate module includes floor information, housing information, resident information, and member tag information within the community, and is associated with "one person, one file".

Actual units refer to information about units within and around the community, including unit names, photos, addresses, and detailed information about employees.

The actual power includes the management of relevant personnel such as neighborhood committee cadres, building leaders, volunteers, security guards, cleaners, and green protection.

Actual equipment refers to the collection of available police equipment and fire-fighting facilities within a residential area. By perceiving the actual power and collecting statistics on the actual equipment, the efficiency and accuracy of handling emergencies can be improved.

The actual security facility module mainly manages various perception devices deployed within the community, including high-definition monitoring, facial capture machines, vehicle micro checkpoints, video access control, WIFI probes, fire perception devices, etc.

The intelligent analysis and circulation processing of community control alarms, reporting events, population perception, vehicle perception, alarm perception and other alarm events are achieved through actual alarm events, realizing a closed-loop management of "alarm push response feedback statistics".

 

3.1.2 Community Business Module

It mainly includes modules such as personnel verification and registration, key personnel and vehicle management and control, and attention to personnel.

The personnel verification registration module has established a community mobile personnel verification mechanism, which compares the perceived and actively discovered personnel at the community level with the population information in real time, thereby achieving normalized control of community personnel.

Establish key personnel and key vehicle management and control modules, and combine community perception technology to achieve control, alarm, and warning management of key personnel and vehicles within the community.

The attention personnel management module establishes a community attention personnel database, which includes elderly people living alone, homeless teenagers, left behind children, impoverished disabled families, etc. The system combines perception data, water, electricity, and gas consumption records for big data analysis, and uses big data intelligence to achieve community care work.

 

3.1.3 Electronic Map

Two dimensional and three-dimensional maps provide visual displays of community information such as "one standard and six reality".

3.2 Application modules

 

3.2.1 Dynamic Perception Application

Realize facial recognition, door opening perception, vehicle passing perception, WIFI perception, fire protection perception, video perception, displacement perception, etc. within the community, and real-time control of various types of information within the community.

The facial perception module obtains the latest facial capture photos, including the capture location and time; And conduct facial comparison to form a personnel video identity database.

The door opening perception module obtains the latest door opening record, including the name of the person opening the door, ID number number, door opening method, time, place, door opening screenshot and short video.

The passing vehicle perception module obtains the latest passing vehicle records, including passing license plate number, time, location, whether entering or leaving, and whether the vehicle is registered in the community.

The WIFI sensing module obtains the latest mobile MAC records of the community through WIFI sniffing.
