摘要
为了提高酒店客房门锁系统的智能化程度,设计了智能酒店门锁控制器。该控制器以MSP430为主控制器,FM17550为射频通信芯片,利用近场通信技术(NFC),结合稳压电路、门锁控制电路、天线电路等实现了使用智能设备NFC方式开启酒店门锁的功能。经测试结果表明,该控制器可以满足智能酒店使用,利用NFC方式开锁时房卡逻辑功能和开锁动作均正确,动态功耗低至140mA,静态功耗低至30mA,感应距离可达5cm,感应时间低至1s。因此该控制器使用方便、高效安全、功耗低、感应效果良好,适合智能化酒店使用。
In order to improve the intellectualization of the door lock system of hotel rooms,an intelligent door lock controller is designed.With MSP430 as the main controller and FM17550 as the RADIO frequency communication chip,this controller utilizes near field communication technology(NFC),combines voltage regulator circuit,door lock control circuit and antenna circuit to realize the function of using smart equipment NFC to open the hotel door lock.The test results show that the controller can meet the requirements of smart hotels.The logic function and unlock action of the room card are correct when NFC is used to unlock the lock.The dynamic power consumption is as low as 140 mA,the static power consumption is as low as 30 mA,the induction distance is up to 5 cm,and the induction time is as low as 1 s.Therefore,the controller is easy to use,efficient and safe,low power consumption,good induction effect,suitable for the use of intelligent hotels.
