Project Overview
The "Internet of Everything" Smart and Safe Community Construction Project in East Lake High-tech Development Zone is one of the top ten people-benefiting projects in Wuhan. Guided by the concept of "joint creation of safety" and adhering to the technical principle of "intelligent integration", the project deploys a series of pan-public security Internet of Things (IoT) element applications based on the city-wide private network IoT for data transmission.
Demand Analysis
Based on the technical standards for smart and safe community construction and the functional requirements of intelligent access control, the following analysis is made:
1. It is necessary to build a standardized and normalized intelligent access control system for unified management, so as to realize personnel control over community unit doors and basement entrances and exits. The system should be easy to integrate and uniformly managed by the Smart and Safe IoT Police Platform. In addition, it should feature replicability, promotability and scalability.
2. On the premise of fully considering data and network security, a fully networked system architecture should be adopted. Based on the public security video private network, Narrowband Internet of Things (NB-IoT) technology should be fully utilized to expand the vertical attributes of the video private network.
3. A full-element IoT database should be established, which can support multiple data types and data structures (both structured and unstructured), and meet the real-time, massive, efficient, secure and other requirements of spatiotemporal data and IoT data applications.
4. An access control authorization and card issuance center should be built in the community, where self-service registration devices are placed to collect community residents' information (including ID cards, fingerprints, irises and portraits).
5. The intelligent access control host should support door opening functions such as card swiping, APP, Bluetooth, visitor authorization and iris recognition. Meanwhile, the device should be equipped with universal interfaces and meet the IP66 protection level.
Brief System Description
The Smart Iris Access Control System centers on database storage technology. It first collects personnel's iris information, then conducts centralized processing of identity information data and grants access rights. In the later stage, it performs identity information comparison, data statistics presentation and analysis, and finally realizes the verification of the legitimacy of community personnel's identity information.

System Composition
The system is mainly composed of portable card issuers, cabinet-type self-service card issuers, intelligent iris access control machines, the Iris Identity Collection Platform, the Iris Data Management Platform and the Iris Access Control Management Platform.
System Process
Project System Features
The collection and recognition terminals of the iris access control channel security system based on iris recognition all adopt advanced recognition technology products - iris biometric devices. Its recognition accuracy is 6-10 times that of fingerprint recognition, with a false acceptance rate (FAR) less than 1/1000 of that of fingerprint recognition, a false rejection rate (FRR) less than 1/10 of that of fingerprint recognition, and an average failure rate less than 1/10 of that of fingerprint recognition. Besides, its recognition speed is 5-10 times that of fingerprint recognition. Therefore, iris technology is an ideal choice. There are no two people in the world with identical irises, because the irises of different people have random detailed features and texture images. The iris around the pupil has a complex structure, which can serve as a unique identifier.
The iris access control management system adopts a non-contact recognition method and can support multiple door opening methods. It grants different access rights to users for multi-level control, and equipment selection should be carried out according to the actual needs of customers during system construction. At the same time, it controls the personnel entering and exiting different areas, specific doors and passages within the project. The iris access control system can realize remote management, and perform functions such as data modification and security key verification. The access control system controller is connected with alarm output and fire linkage expansion interfaces, and has fire alarm and emergency door opening functions. When a fire switch signal is received, all doors under the jurisdiction of the access control system controller will open automatically.
User Feedback
The entire system has been operating normally, and the work of information collection and card issuance has been completed. It not only serves the "One Standard and Three Realities" work of the public security system (for monitoring key personnel) but also supports community property management and ensures the safety and convenience of owners' entry and exit. It has greatly improved the intelligent construction of the community.
