With the rapid development of Internet software and hardware technology, access control system is required in industrial and scientific research occasions to record the exact number of people left in a certain place in real time, at the same time, it can inform the number of people on the site of access control system through ethernet. This work has completed a kind of network technology based on embedded system.
The security access control systems use standard electrical interface to integrate bar code card, ID card, IC card and other reading and writing devices into the access gate equipment, thus providing orderly and civilized access mode for entry and exit personnel, and eliminating illegal personnel from entering and leaving. At present, the gateway gate control system equipment includes traditional wing gate, swing gate and three-roll gate. With the development of technology, barrier-free channel gates and arm gates have gradually emerged. The different appearance of channel gate equipment will bring different experience to different use occasions.

It is often used in the management of pedestrian passages and automatic ticket selling and checking, such as government agencies, factories and enterprises, intelligent buildings, residential districts, scenic spots and venues, colleges and universities, kindergartens, stations, leisure and entertainment places, etc.
4. Arm gate security access control systems are simple and beautiful. Flexible length of arm can be used in standard channel and wide channel occasions. It also has ultra-thin body and saves installation space. It can be widely used in high-end business places, exhibition centers, classical ticket entry and exit, public transport and other industries.
