摘要:移动通信中为了保证场强覆盖,基站站址的确定、基站天线高度的设计最基本也是最重要的工作之一,选择基站位置和高度的方法一般是通过经验公式来预测,而实际测量的工作量则非常大,而且耗费大量时间,费用也很高。78832
本课题的目的是开发一种基于无人机平台的场强测试工具,通过使用无人机加载场强测试模块,可以大大提高无线通信系统设计阶段对无线场强信号测量的准确度,即可以得知场强覆盖所需的天线高度范围,在合适的地方设置无线通信铁塔及基站设备,可以节省大量基础建设的成本和改进无线通信网络质量,同时也可以对奥村模型进行更近一步的测量和更新。对于场强测试模块开发将采取的方案是:使用现有的模块进行合理的组合,从而达到控制器与接收器之间的通信,并设计无人机搭载平台,通过红外模块实现与空中场强测试模块通讯,并把数据存入SD卡,最后在PC端完成数据处理。

Development of Wireless Field Strength Test Technology Based on Unmanned Aerial Vehicle
Abstract:In the mobile communication, in order to ensure the coverage of the field strength, the determination of the base station site, the design of the base station antenna height is one of the most basic and most important work。 The method of selecting the position and height of the base station is generally predicted by the empirical formula, The amount is very large, and spend a lot of time, the cost is also high
The purpose of this project is to develop a field-based testing tool based on the UAV platform。 By using the UAV-loaded field strength test module, and also to make a further measurement of the Olympic model。 And update。 For the field strength test module development will take the program is: the use of existing modules for a reasonable combination, so as to achieve communication between the controller and the receiver, and design UAV platform, through the infrared module and air field strength Test module communication, and the data into the SD card, and finally in the PC side to complete the data processing。
