Abstract： In order to solve the problem of pet lost and difficult to retrieve, a design of pet anti lost wearable device based on Internet of Things technology is proposed.In the short distance of the system, through the low-power Bluetooth 4.2 module, the WeChat applet of mobile phone can control and play the music of wearable device and light up the colorful led to prompt the pet′s position. At the same time, with the help of the speech recognition module, the wake-up system can be used, and the user can also complete the above operations by saying the secondary keywords.Outside the Bluetooth signal range, the user can check the location and speed information collected by the GPS + GPRS location module on the pet wearable device in the WeChat applet. The experimental results show that the system has perfect functions, the Bluetooth control distance of WeChat small program end reaches 80 m, the GPS positioning accuracy error of wearable device is controlled within 2 m, and the voice recognition function is stable, which can help the owner to find and control the pet in time，and avoid the potential safety hazard and property loss caused by pet loss.

物聯(lián)網概念在1999年正式提出，顧名思義就是“物與物相連的互聯(lián)網”，目前國內的定義是：通過傳感器、無線射頻技術(Radio Frequency Identification，RFID)、全球定位系統(tǒng)等信息傳感設備，按約定協(xié)議，把任何物品與互聯(lián)網連接起來，進行信息交換和通信，以實現(xiàn)智能化識別、定位、跟蹤、監(jiān)控和管理的一種網絡[2]。2016年9月微信小程序面世，在微信生態(tài)下，觸手可及、用完即走的微信小程序引起廣泛關注，微信公開數(shù)據(jù)顯示，小程序日活已達2.8億，人均使用20個小程序，人均使用時長超過10 min。因此越來越多的開發(fā)者將用戶端的操作移植到了微信小程序端，相信以微信小程序作為用戶端的設備開發(fā)更容易被市場所接受。
