基于跳频通信的移动机械遥控系统

A Remote Control System for Construction Machinery Based on FHSS

摘要:

为解决在同一个工作区域多个无线通信网络容易彼此干扰无法协同工作的问题，以移动机械工程车辆为控制对象，设计JRCJ500无线遥控系统，由用户手持终端接收用户操作指令，现场控制器驱动远程设备动作，实现对车辆的远程操作控制与状态信息反馈；采用STM32L低功耗处理器设计无线通信模块，选择公用通信频段，基于跳频扩频通信技术，约定无线通信数据格式与跳频频点，通过简单高效的跳频图案生成算法，在每一帧数据中添加同步字头，实现了无线通信网络的快速同步组网，保证了通信的稳定性，实现了在限定工作区域多台无线通信设备同时工作的应用需求。由于采用模块化设计，系统具有良好的通用性和可移植性，能够在多种复杂恶劣工作场合实现远程控制功能。

Abstract:

Aiming toSsolve the problem that several wireless networks cannot work together in the same region, JRCJ500 wireless remote control system is designed and realized for mobile construction machinery based on FHSS.SThe synchronous network can be carried out rapidly and work steadily because of the simple but efficient frequency hopping algorithm. The wirelessSsystem, with good generality and transportability, can be used widely in a variety of complex and harsh operating conditions.
