Abstract

本发明涉及一种抗干扰泊车雷达装置，适用于机动车行车及泊车时探测行车方向是否有障碍物，是对现有泊车雷达系统的改进。在传统泊车雷达的发射器上加入验证码调制模块，使其发射带有验证编码的复合波形的超声波；在接收器上加入验证模块，对于接收到的回波如果不能解码出验证码则作为干扰波丢弃，以避免因外界噪声干扰造成的误报。

Description

一种抗干扰泊车雷达装置
技术领域
本发明涉及一种抗干扰泊车雷达装置，适用于机动车行车及泊车时探测行车方向是否有障碍物，是对现有泊车雷达系统的改进。
背景技术
超声波探测雷达广泛应用于机动车以辅助驾驶员判断行车方向上是否有障碍物。由于路况情况复杂，泊车雷达很容易被环境噪声(例如大型车辆的发动机噪声)影响造成误报。驾驶员会因此精神紧张，甚至会因为采取了不适当的应对动作而造成交通事故。
发明内容
本发明涉及一种抗干扰泊车雷达装置，适用于机动车行车及泊车时探测行车方向是否有障碍物，是对现有泊车雷达系统的改进。在传统泊车雷达的发射器上加入验证码调制模块，使其发射带有验证编码的复合波形的超声波；在接收器上加入验证模块，对于接收到的回波如果不能解码出验证码则作为干扰波丢弃，以避免因外界噪声干扰造成的误报。
附图说明
附图是一种波形调制示意图。固定频率及振幅的初始波形与作为验证码的方波叠加，按照验证码设定的模式形成有通断规律的发射波形。
具体实施方式
该装置由超声波发射模块，超声波接收模块，距离计算及提示模块构成。
超声波发射模块：由超声波音频震荡电路产生固定频率、振幅的电流，经过验证码调制电路使该电流与验证码波形调制在一起，然后经过信号放大电路及发射器向周围发射超声波。
超声波接收模块：超声波接收器把感应到的超声波转换成电流。该电流经过验证码解调电路分离出固定频率的超声波波形和验证码波形，如果验证码波形与本机发射的验证码相符则把解调后的超声波电流传递给距离提示模块，否则作为干扰波丢弃。
距离计算及提示模块：对输入的电流计算障碍物距离并根据距离远近作相应的声音及视觉提示。
