Background
Along with development of information technology and popularization of mobile internet, various intelligent terminal devices, particularly intelligent mobile phones, are increasingly widely applied, and great convenience is brought to daily life of people.
The object searching is a frequently encountered thing of people in daily life. People may forget the last place to place the article to be used by themselves when needed for various reasons, so that a lot of time is spent on finding the article, and even some influence on work or life may be caused by the fact that the article cannot be found at one time.
The electronic tag which can be identified by the intelligent mobile phone is arranged on the article, the electronic tag sends out information representing the characteristics of the article through wireless signals, and when a person forgets the last placement position of the article, the wireless signals sent by the peripheral tag can be received only by opening the mobile phone, so that the tag is judged to be in a certain peripheral range. Furthermore, through the built-in sound/light/electricity module of the tag, when the mobile phone finds that the tag is at the peripheral position, the tag can be controlled to send out sound/light/electricity signals through wireless signals, so that a user can be helped to quickly find out articles bound with the tag.
The low-power consumption Bluetooth technology is a very popular wireless communication technology on the smart phone at present, and has the characteristics of low power consumption and low cost. WeChat is taken as one of application software with highest popularity on smart phones in China, and the domestic user quantity exceeds 10 hundred million. Therefore, a set of tag information identification system is realized based on the WeChat applet and the low-power consumption Bluetooth technology, is used for searching and positioning articles in daily life of people, and has extremely low user use threshold and wide use scene. However, in the specific implementation process, the following engineering problems need to be solved to achieve better user experience:
1. because of the very popular bluetooth equipment, the applet client can search a lot of bluetooth equipment signals irrelevant to micro-credit users when scanning the peripheral bluetooth equipment, and the user needs to manually screen, so that the user experience is poor;
2. many times personal items are in the personal privacy category, and users do not want others to find their personal items;
therefore, how to quickly and safely help users find personal articles which only belong to the users is a problem which needs to be solved with emphasis. WeChat is used as a mobile application program with real-name authentication and has user identity uniqueness. The WeChat applet client user application ID generated based on the unique user identity is also unique, and is used for configuration of the tag and encryption of communication data, so that association of the tag device and the WeChat personal identity can be realized very simply, conveniently and safely, and convenience and safety in the identification process of the personal tag device are improved.
