The Design And Implementation Of The Hotel Smart Door Lock System Based On WeChat Hardware Platform

Under the great age of the Internet of things now, all kinds of intelligent solutions emerge in endlessly, intelligent equipment constantly go into people's life.In the Internet age, the hotel industry have been went toward the development of economy and business in order to decrease face-to-face human services in essence.If hotel door lock device can be combined with WeChat hardware platform, with the help of WeChat the widely use of social software, not only the check in multifarious formalities and the manpower can be saved, greatly enhance efficiency, but also increase the stickiness of users.And if the lock technology implementing on the App that is system level, the development costs will be increased because of the diversity of the platform.This article puts forward the idea that WeChat intelligent hardware platform combined with hotel door lock device is exactly based on this background , at the same time,the article alse puts forward a new solution to the Internet of things in the hotel industry, which is combining the hotel business and the basis interfaces of the hardware platform to provide a hotel door lock system based on wechat unlock which is safe and reliable. WeChat hardware platform to provide AirSync based on bluetooth technology, makes devices direct communication via bluetooth and WeChat client, and through WeChat public get user information, so as to realize the function of equipment and WeChat direct interconnection.In this system, nrf51822 development board simulate bluetooth door lock device,the user to open the door key is no longer an IC card or other types of room card, but the only equipment qr code corresponding to the room.Users in the previous hotel clients use WeChat authorization way to log in to determine identity, after successful reservation can obtain corresponding room door lock device qr code, through WeChat scan qr code into public number device for subsequent unlock operation. Considering the security check-in, this paper puts forward a set of security solutions.In the process of the lock, the system joined the identity authentication scheme based AES and the improved RC4 algorithm to encrypt device key and improve the security and reliability of the system.
