摘要
为了提高工作机的测距能力,测距系统不仅要对所测距离具有快速精确的判断,而且必须具备较高的抗干扰能力。基于伪随机序列的无线电测距系统利用QPSK原理调制M序列,然后通过无线电发射作为测距介质,具有测距范围广、抗干扰能力强的特点。同时系统采用TMS320F28335作为运算和控制的主控芯片,具有精确度高、实时性强的特点。实验数据证明了无线电测距系统的可行性。
In order to improve the ability of working machine range,ranging system should not only have quick and accurate judgement for the measured distance,and must have a high anti-interference ability. Using the QPSK principle,the M sequence is modualted by radio ranging system based on pseudorandom sequence,and then the M sequence is transmitted by radio as the distance measuring medium,which has the characteristics of wide ranging and strong anti-interference ability. At the same time,the system uses TMS320F28335 as the main control chip to comput and control,which has the characteristics of high accuracy and strong real-time. The experimental results show the feasibility of the system.
