摘要
随着宠物在家庭中地位的提升，宠物的安全与行踪追踪成为养宠人士关注的重点。传统的宠物追踪方式多依赖项圈式定位器，存在定位精度低、信号覆盖弱、数据传输滞后等问题，难以满足实时、精准追踪宠物的需求。
基于 STM32F103C8T6 单片机的智能宠物追踪器，整合了 GPS + 北斗双模定位模块、OLED 显示屏、AIR7804G 移动网络模块、声光报警模块及相关电源电路，实现了宠物位置的精准获取、实时显示与远程追踪。系统核心功能包括：通过 GPS + 北斗双模定位模块获取宠物当前所在位置的经纬度，确保在复杂环境下仍能稳定定位；借助 OLED 显示屏实时显示经纬度信息，方便近距离查看；利用 AIR7804G 移动网络模块将定位数据传输至手机端，实现远程实时追踪；当手机端发出指令时，触发追踪器上的声光报警模块，通过声音和光线提醒找到宠物。
该系统的实现，有效提升了宠物追踪的精准度与实时性，解决了传统追踪方式的诸多弊端，为养宠人士提供了便捷、可靠的宠物安全保障方案，同时为同类智能追踪设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the increasing status of pets in families, the safety and tracking of pets have become a focus for pet owners. Traditional pet tracking methods mostly rely on collar-type locators, which have problems such as low positioning accuracy, weak signal coverage, and delayed data transmission, making it difficult to meet the needs of real-time and accurate pet tracking.
The intelligent pet tracker based on the STM32F103C8T6 microcontroller integrates GPS+Beidou dual-mode positioning module, OLED display, AIR7804G mobile network module, sound and light alarm module and related power circuits, realizing accurate acquisition, real-time display and remote tracking of pet positions. The core functions of the system include: obtaining the longitude and latitude of the pet’s current location through the GPS+Beidou dual-mode positioning module to ensure stable positioning in complex environments; real-time display of longitude and latitude information through the OLED display for convenient close-range viewing; transmitting positioning data to the mobile phone through the AIR7804G mobile network module to achieve remote real-time tracking; when the mobile phone sends a command, triggering the sound and light alarm module on the tracker to remind to find the pet through sound and light.
The implementation of this system effectively improves the accuracy and real-time performance of pet tracking, solves many drawbacks of traditional tracking methods, provides a convenient and reliable pet safety guarantee scheme for pet owners, and also provides a reference for the research and development of similar intelligent tracking devices, with high practical application value.
