用STM32F101或者STM32F103单片机，对华为GPRS模块MG323或其他兼容模块进行设置，实现远程数据的传送，源码经过测试可行，用户应将 IP：PORT 填完整(Use STM32F101 or STM32F103 microcontroller, huawei GPRS module MG323 or other compatible module Settings, realize remote data transmission, source tested feasible, users should be fill full IP: PORT )

一种简单实现无线传感器网络时间同步的HRTS算法(A simple wireless sensor network time synchronization algorithm HRTS)

本系统是一套机载数据采集模块和远程终端。数据采集模块可以独立采集对象（小型飞机或航模）的姿态、高度等参数，并通过无线方式发送到远程终端；远程终端具有数据的实时显示、报警功能，并可记录数据完成回放。 在本设计方案中，使用MPU6050模块测量小型飞机的姿态角、航向角，使用气压测量模块与超声波测量模块来确定飞机的高度，使用WIFI模块进行数据传输，使用北斗卫星定位模块进行小型飞机的位置确定，在远程终端PC机上对数据进行解算，并采用MATLAB GUI对采集到的数据进行图形化的显示。(This system is a set of airborne data acquisition module and remote terminal. The data acquisition module can independently collect the attitude and altitude parameters of the object (small aircraft or model) and send them to the remote terminal by wireless mode. The remote terminal has the functions of real-time data display and alarm, and can record and play back the data. In this design, MPU6050 module is used to measure the attitude angle and heading angle of small aircraft, air pressure measurement module and ultrasonic measurement module are used to determine the height of the aircraft, WIFI module is used to transmit data, Beidou satellite positioning module is used to determine the position of small aircraft, and data is obtained on remote terminal PC. The calculation is carried out, and the collected data is displayed graphically by using MATLAB GUI.)
