数据采集监测计算伴随着微型计算机技术的快速发展，通过计算机处理，系统将采集的模拟信号转变成数字信号，得出数据，这些采集到的实时数据反映着不同的运行状态，并可以接收运行需要发出的各种命令。在各个领域中，不论是简单到复杂还是从表面到深入，数据采集系统的身影几乎无处不在，所以本课题的研究有着广阔的前景和经济价值，自二十世纪50年代到70年代以来，人们见证了数据采集系统的诞生与发展，从初步认可到逐渐分类，随着微型机的反正也诞生了许多性能优良的数据采集系统，但是在计算机普及之后，数据采集系统发生了巨大发展，然而数据采集系统需要的是不断地测试和完善系统的各项功能，如实时采集、进行记录、反应故障等，整个性能的优劣将受到数据采集的性能特点直接影响，足可见数据采集系统的重要性，因此对于数据采集系统需要不断完善和提升，是今后发展的一个主要方向[1]。(The ongoing developing of information technologies, in many areas, such as communication, control and monitoring, etc., the signal processing technology is becoming more and more widely applied to computer, the analog acquisition and processing in modern industrial control and research. The reliable operation of power system substation, especially the problem of remote monitoring unmanned substations, the merits of the entire property will be subject to the performance characteristics of the data collected directly affect, enough to see the data the importance of the system of acquisition.)

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.)

说明：  使用超声波测量距离，可以参考一下这个代码，适用于32。(Using ultrasonic to measure distance, you can refer to this code, which is suitable for 32.)
