Description

带警示有车靠近的倒车雷达
技术领域
本实用新型属于汽车电子技术领域，具体涉及一种带警示有车靠近的倒车雷达。
背景技术
在汽车的安全防护中，可采用多种方法和产品来保护汽车自身的安全，比如倒车雷达，其在汽车倒车时能发出警示信息，以有效避免汽车与障碍物发生碰撞。但是，目前的倒车雷达产品仅在汽车倒车时起到作用，若汽车处于停车状态，则对其他靠近的车辆没有警示作用，从而容易导致当汽车停泊而主人不在时，汽车被其他靠近车辆碰撞的事故发生。
发明内容
本实用新型的目的在于针对上述问题，提供一种带警示有车靠近的倒车雷达，可有效避免当汽车停泊而主人不在时被其他靠近车辆碰撞的事故发生。
为达到上述目的，本实用新型的技术方案如下：带警示有车靠近的倒车雷达，包括主机和传感器，主机包括CPU电路、运放电路、转换电路、接收发送电路、检测电路和电源部分，CPU电路的输入端与运放电路、检测电路、电源部分的输出端相连；CPU电路的输出端与转换电路的输入端相连；运放电路的输入端与转换电路的输出端连接；转换电路与接收发送电路相互连接；电源部分输出端与转换电路和接收发送电路的输入端相连；主机还包括用以警示有车靠近的警示源及用以控制警示源的控制电路，该控制电路与CPU电路的输出端及电源部分的连接。当汽车处于停泊状态时，能自动检测来车靠近距离并发出警示信息。
上述控制电路由继电器控制电路及继电器接插件部分组成，继电器控制电路与CPU电路的输出端及电源部分的连接。
上述警示源为发光装置，或发声装置，或两者的结合。所述发光装置为汽车的方向灯，及所述发声装置为汽车的喇叭。
上述传感器安装在汽车的前部和后部，汽车前部和后部的传感器数量均以2～6个为宜；此外，汽车的左右两侧也可安装传感器，以保证能检测到来自汽车前、后、左、右四个方向的靠近车辆。
上述检测电路包括脚刹、倒档和上电检测。
有一显示器接口，与CPU电路的输出端相连，显示器接口与显示器连接。
有一音响控制端，其通过继电器接插件部位与继电器控制电路和电源部分连接。汽车在倒车过程中若汽车音响打开，则当测试到障碍物很近时，系统会自动停止汽车音响的工作，使倒车雷达报警声更加明显，提高倒车的安全性。
本实用新型结构简单，当汽车停泊在停车场里而主人不在时，能对其他靠近车辆发出警示信息提醒来车注意，避免意外发生。

现结合附图和实施例对本实用新型作进一步说明：
具体实施方式
如图1、图2所示，本实用新型由主机和传感器I组成。主机由CPU电路D，运放电路F，转换电路E，接收发送电路J，显示器接口电路G，脚刹、倒档和上电检测电路H，电源部分A，继电器控制电路C和继电器接插件部位B组成。CPU电路D的输入端与运放电路F，电源部分A和脚刹、倒档和上电检测电路H的输出端相连；CPU电路D的输出端与显示器接口G，转换电路E，继电器控制电路C的输入端相连；运放电路F的输入端同转换电路E的输出端连接；转换电路E同接收、发送电路J相互连接；电源部分A输出端同转换电路E，接收、发送电路J，继电器控制电路C的输入端相连；汽车方向灯K、汽车喇叭L和音响控制端M通过继电器接插件部位B同继电器控制电路C和电源部分A连接。传感器I安装在汽车的前、后部，分别为4个。
本实用新型的工作流程是这样的：利用汽车本身的刹车灯正极、倒车灯正极以及ACC检测信号电压作为倒车雷达的工作触发电压，当刹车、倒车或停车时的触发电压输入主机中CPU电路时，该信号被转换成能被CPU电路中的单片机接收的信号，单片机发出指令给转换电路，使转换电路进入工作状态，同时又发出一个信号给接收发送电路并升压为一个电平较高的超声波信号驱动超声波发射接收传感器，由于障碍物对超声波产生反射，当传感器接收到反射信号时，反射回来的信号给运放电路进行选频放大后转换为能被单片机接收的指令信号，CPU电路会根据发射和接收之间的间隔时间差，计算出障碍物与传感器之间的距离。同时CPU电路发出相应的信号通过显示器接口电路给显示器，使显示器作出相应的变化。供车辆驾驶员对本车的动向作出准确的判断。
如图3所示，在ACC无电、汽车11处于停车状态而车主又不在时，若汽车22靠近汽车11到一定的距离，汽车11前、后部的传感器则发送信号至CPU电路，CPU电路接收到该信号后会通过继电器控制电路使汽车方向灯闪烁和喇叭报警，以警示靠近的车辆注意，达到减少意外的发生。
汽车在倒车过程中若汽车音响打开，则当测试到障碍物很近时，CPU电路会通过继电器控制电路及音响控制端自动停止汽车音响的工作，使倒车雷达报警声更加明显，提高倒车的安全性。
以上描述只是本实用新型一个特定的实施例，本实用新型并不仅局限于以上图示或描述的特定结构，权利要求将覆盖本实用新型的实质精神及范围内的所有变化方案。
