With the rapid economic development, people have higher and higher requirements for science and technology to serve life, and the security and access control pedestrian passage industry has also achieved rapid development. Technical defense products based on a variety of modern information science and technology have become an important protective barrier for the social security environment. A detailed description of several functions that must be possessed by the access control and pedestrian passage management system for the migrant population in the future:

　　 One, large capacity

The door access control and pedestrian passages for the floating population usually take the village as a unit to construct the access control system of rental houses. Smaller villages have dozens of buildings, hundreds of buildings, and larger villages may exceed 500 or even close to thousands of buildings. Calculating from 50 to 100 people in a building, a village's floating population may have a population of nearly 100,000. The access control system of all buildings in the entire village must be built on a platform software, which puts higher performance requirements on the platform software and hardware equipment, so the platform design capacity requirements of the pedestrian passage system for the floating population can reach 2000 buildings. , 100,000 population.

　　 2. Swipe to respond quickly

The floating population access control pedestrian passage system manages a large population, and the controller stores all the personnel and permissions of the entrance and exit where it is located offline. For the entrance of a large rental housing community, there may be nearly 100,000 offline storage in a controller. People, the controller is required to quickly swipe the card to open the door even when 100,000 people are stored offline (swiping response time<0.2 seconds), and does not affect the normal entry and exit of personnel (especially during peak hours).

　　 Three, video linkage

　　 In some communities with ample funds, in addition to deploying access control and pedestrian passage systems for floating populations, video linkage functions are also considered, so the performance of video linkage capture will also appear very important. Most of the floating population living in rental housing are migrant workers, and there will be a peak commute in the morning and evening. Taking 100,000 people in a 1,000 building as an example, the number of swiping cards to open doors and snapshots during the one-hour peak in the morning will reach 70,000 to 80,000 times (excluding the number of elderly and children), and the average number of swiping cards and snapshots per second From 19.4 times to 22.2 times, the highest peak will reach about 48 times per second. In order to cope with the pressure of these actual data, the system must meet 48 swipes and snapshots per second (capture video capture photos) for at least 3 hours under the information volume of 100,000 people. The an obvious sense of delay (not more than 1 second); the time to open the door is less than 0.2 seconds by swiping the card. And the platform operation should be very smooth during peak periods.

　　Four, real-time two-way active transmission of data

　　 Data real-time two-way active transmission is the basic factor for the realization of the high performance of the access control pedestrian passage system for the floating population. When the network is unblocked, the platform and front-end data require two-way real-time transmission; when the network is interrupted, the data will be actively sent after the network is restored.

　　 Real-time active uploading: The events and alarm information generated by the front-end are related to the safety of the entire system. Therefore, all events and alarms on the access control pedestrian passage project of the floating population require all events and alarms to be uploaded to the platform in real-time, so that the management center can take timely countermeasures. When the network is unblocked, after an alarm occurs at the front end, the alarm information is required to be uploaded to the platform and displayed on the operation interface of the platform software within 2 seconds.

Automatic synchronization download: The mobile population access control pedestrian passage project requires a large amount of equipment and a large population. In order to improve the convenience of platform operation and management, all equipment parameter settings and personnel data in the system are required to be automatically synchronized and downloaded to the front-end control in real-time When the management personnel modify the parameter settings of the door point controller on the platform software or add a new personnel authorization in the building where the controller is located, the door point can immediately open the door by swiping the card, without the need for a separate download operation.

In the future, more technologies will be applied to all-in-one access control machines, which will make it easier to demonstrate the advantages of flexibility, mobility, and convenience of all-in-one access control machines. It will be the development direction of key technologies of all-in-one access control machines and the inevitable trend of the entire access control machine market. . As an access control product manufacturer and sales manufacturer, S4A will expand new markets and create a new product system in the process of R&D and production of access control pedestrian passage products.
