Description

一种车载呼叫对讲器 技术领域
本实用新型涉及一种车载对讲器，更具体的说，本实用新型主要涉及一种车载呼叫对讲器，可以装在车外部，便于车主远离车辆时与车辆附近的人员进行远距离对话，适于交警处理违停或其他急需挪车的情况。
背景技术
目前，交警处理违停或其他急需车主挪车时，车主往往距离车子较远，无法及时得知相关信息，造成了不必要的麻烦。现有做法是车主在车子上留上车主联系信息，便于相关人员与车主及时联系，这样做极大的泄露了个人隐私，极其为不法分子利用。市面上的车载对讲设备大都安装在车内，车主不在车辆内或车辆附近时无法启用，不能满足该需求。鉴于此，需要一种新型车载对讲设备，既能及时联系远离车辆的车主，又不泄露车主的隐私。
实用新型内容
本实用新型的目的在于针对上述不足，提供一种车载呼叫对讲器，既能及时联系远离车辆的车主，又不泄露车主的隐私。
为解决上述的技术问题，本实用新型采用以下技术方案：
一种车载呼叫对讲器，包括壳体和线路板，其特征在于：所述壳体上设置有按键、咪头及咪头孔、扬声器及扬声器孔，所述线路板设有电源接口、主控芯片、与主控芯片连接的音频输入输出模块、与主控芯片连接的呼叫输入输出模块，所述音频输入输出模块与音频输入输出接口连接，所述音频输入输出接口与咪头和扬声器连接，所述呼叫输入输出模块与呼叫输入输出接口连接，所述呼叫输入输出接口与按键连接。
进一步的，所述壳体上设有摄像头。
进一步的，所述主控芯片还连接有降噪模块。
更进一步的，所述降噪模块设于壳体内。
进一步的，所述主控芯片还连接有移动通信模块或WIFI模块。
进一步的，所述咪头为高保真镀银振膜电容咪头。
与现有技术相比，本实用新型的有益效果是：
1、将车载呼叫对讲器安装在车辆外部并与车内电源和车载支持通信对讲功能的设备如DVR连接，需要联系远离车辆的车主时，按下按键，即可启动车载呼叫对讲器，通过网络与车主手机APP进行语音对讲，及时应对交警处理违停或其他急需车主挪车状况，又不泄露车主的隐私；
2、当主控芯片连接有移动通信模块时，将车载呼叫对讲器安装在车辆外部并与车内电源连接，需要联系远离车辆的车主时，按下按键，即可启动车载呼叫对讲器，通过网络推送到与车主手机APP进行语音对讲；
3、底壳上设螺栓孔，便于用螺栓螺帽将车载呼叫对讲器安装在车辆后视镜或牌照框处等车体外部，与车内电源连接方便。
附图说明
图1为本实用新型实施例1的结构示意图；
图2为本实用新型实施例1线路板的结构示意图；
图3为本实用新型实施例1线路板的工作原理图；
图4为本实用新型实施例2的结构示意图；
其中，1为壳体、2为咪头孔、3为扬声器孔、4为按键、5为线路板、6为音频输入输出模块、7为主控芯片、8为输入输出呼叫模块、9为电源接口、10为摄 像头。
具体实施方式
下面结合附图对本实用新型作进一步阐述。
实施例1
如图1-2所示，一种车载呼叫对讲器，包括壳体1和线路板5。壳体1上设有咪头及咪头孔2、扬声器及扬声器孔3、按键4，咪头和扬声器(图中未示出)设于壳体内与咪头孔2和扬声器孔3的相应位置。线路板5上设有电源接口9、主控芯片7、音频输入输出模块6、呼叫输入输出模块8。
车载呼叫对讲器的工作原理如图3所示，主控芯片7与音频输入输出模块6、呼叫输入输出模块8、电源接口9连接，音频输入输出模块6连接有音频输入输出接口，音频输入输出接口与咪头和扬声器连接，呼叫输入输出模块8连接有呼叫输入输出接口，呼叫输入输出接口与按键4连接。
主控芯片采用MT5350控制芯片，音频输入输出模块采用NV065A音频处理芯片，呼叫输入输出模块采用ATA2508指令发送芯片。咪头采用高保真镀银振膜电容咪头，拾音效果好，声音清晰自然。
底壳上设置螺栓孔，通过螺栓将车载呼叫对讲器安装于后视镜处或牌照框处，便于与车内电源和车载支持通信对讲功能的设备连接。将车载呼叫对讲器安装在车辆外部并与车内电源和车载支持通信对讲功能的设备如DVR连接，需要联系远离车辆的车主时，按下按键，即可启动车载呼叫对讲器，通过网络推送到手机端APP与车主进行语音对讲，及时应对交警处理违停或其他急需车主挪车状况，即不泄露车主的隐私。
实施例2
如图4所示，在实施例1的基础上，壳体1上还摄像头10。车载呼叫对讲器安装在车辆外部并与车内电源和车载支持通信对讲功能的设备如DVR连接，同时将摄像头与DVR连接，实现网络和手机APP对接进行呼叫对讲，同时联机启动DVR传输摄像头拍摄的画面，实现可视功能，便于车主判断呼叫人的身份，以确定是否挪车。
主控芯片采用MT5350控制芯片，音频输入输出模块采用MC34018音频处理芯片芯片，呼叫输入输出模块采用ATA2508指令发送芯片，视频输入输出模块采用OV9712视频处理芯片。
实施例3
在实施例1的基础上，主控芯片还连接有降噪模块，以增强咪头采集到的音频信号清晰度。
实施例4
实施里3中是将壳体和线路板集成在一起安装在后视镜或牌照框处，也可将壳体和线路板分开以电线连接，缩小了产品尺寸、便于安装，同时将降噪模块设于壳体内，以避免咪头与主控芯片间线路增长而降低音频信号传输效果。
实施例5
在实施例1的主控芯片上增加移动通信或网络模块，采用3G 4G移动通信模块或WIFI网络模块。这样就可以不用匹配车载支持通信对讲功能的设备使用，只需在车载呼叫对讲器后端装上移动通信卡即可连接到网络。将车载呼叫对讲器安装在车辆外部并与车内电源连接，需要联系远离车辆的车主时，按下按键，即可启动车载呼叫对讲器，通过网络与车主进行语音对讲。
以上所述,仅本实用新型的较佳实施例而已,并非是对本实用新型作其它形式的限制,任何熟悉本专业人员可以利用上述揭示的技术加以变更改进.但凡是未脱离本实用新型技术方案内容,依据本实用新型技术实质对以上实施所作的任何简单修改，仍属于本实用新型技术方案的保护范围。
