基于Modbus-RTU的水面航行平台无线动力控制系统

某水面航行平台模型需要在开阔水域进行自航试验,试验人员需在岸上对模型上的4台推进器电机和4台回转电机进行精确控制从而控制模型的运动,由于模型体积较小且能承载的重量较小,针对该问题设计了一套结构简单、成本较低的水面航行平台无线动力控制系统,该系统基于Modbus-RTU协议、通过串口控制电机。实际测试结果为该系统能够实时控制伺服电机的转动速度和转动角度,最远控制距离在1 km左右,控制误差在3%以内,结果表明该系统能够满足试验需要。

Wireless power control system for surface navigation platform based on Modbus-RTU protocol

A surface navigation platform model needs to conduct self-propelled test in open water,and the experimenters need to control the four thruster motors and four rotary motors of the model on shore,so as to control the movement of the model.Because the model is small in volume and can carry small weight.Aiming at this problem,a set of simple structure and low cost control system is designed.The system is based on Modbus-RTU protocol and controls the motor through serialport.The actual test result shows that the system can control the rotation speed and angle of the servo motor in real time,the maximum control distance is about 1 km,and the control error is within 3%,which shows the system can meet the needs of the test.
