Smart access control solutions based on SEMTECH and STMicroelectronics.
With the development of wireless communication technology, it has the advantages of strong connection, easy to install, high elasticity, high elasticity, so that the application of wireless network is not limited. Wireless RF Access Control Systems not only provide better security and reliability, but also relatively traditional fit mechanical devices, wireless RFID / XINPIN / MENJINKAOQIN / 'TARGET =' _blank'> Access control system has less wear consumption, It is possible to extend the use time and effectively reduce the replacement of access control equipment.
Daciber Friends launched SEMTECH SX1276 / 78 and traditional STM32F103 smart access control solutions with lower operating voltages and variety of working modes, which reduced power consumption, which is under the trend of current environmental protection It is undoubtedly important.

Scenary characteristics:
The hardware of the wireless access control system mainly includes several parts of other interface devices such as master devices, electronic control locks, power, speech compression / control platforms, and wireless transmission platforms. When the authorized user card is opened, the card reader transmits a certain frequency of RF signal transmitted through the transmit antenna. When the RF card enters the operating area of the transmit antenna, the induction current is generated, the RF card can be activated, and the information such as self-coding is transmitted. The internal antenna is issued, the system receiving antenna receives the modulation signal sent from the RF card. The antenna regulator is transmitted to the card reader, and the card reader is demodulated and decoded to the main control. The device performs related processing. The master system determines the legality of the card based on the logical operation, and makes corresponding processing and control for different settings, and issues an instruction signal control executive action. If you are authorized to forget the card, you can also open the door through the system's external keyboard.
Functional requirements:
Authorized users (resident): open the door to the authorized user, can be swindled or using the mobile app.
Non-authorized users (visiting guests): For non-authorized users, they can contact the indoor households through the calling equipment. After confirming the identity, the residents open the access control.
Illegal intrusion (thief, etc.): When you encounter an attempt to destroy the access control system and other illegal means, the system can automatically prepaid emergency notification to the community.

Performance requirements:
Safety: The system prevents all non-authorized objects from entering and ensuring property safety.
Reliability: The system can work stably, resist external interference, and ensure the accuracy of action.
Real-time: The system can respond to user objects in real time.
Flexibility: The system has higher expansion, easy to add new users.
Confidentiality: The system has strong anti-cracking capabilities, which has a stronger user password protection. (Editor: Ioter)
