具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。本发明中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请同时参阅图1和图2,本发明实施例提供的车载系统包括温判有物提示装置、车辆电瓶、左右警示灯模块(即左警示灯和右警示灯)、蜂鸣模块和移动终端。所述温判有物提示装置与车辆电瓶、左右警示灯模块和蜂鸣模块电连接,温判有物提示装置与移动终端通讯连接;所述移动终端输出模式指令来设置温判有物提示装置的提示方式,所述车辆电瓶对温判有物提示装置供电,所述温判有物提示装置检测车辆左右侧(也可单检测左侧或右侧,根据实际情况来定)的第一预设范围内的温度并在第二预设范围内发射信号(若第二预设范围内有物则信号被反射,形成对应的反射信号),判断所述温度满足设定条件时或收到反射信号时,根据设置的提示方式进行有物提示。
通过温度来判断车辆左右侧是否有物并提示,相比于现有的左右凸形镜,不会因阳光或灯光影响视物效果,且主动提示无需驾驶人分心;结合反射信号的进一步判断,确保车辆左右侧有物判断的准确性,大幅度降低与左右车道的物体相撞的风险。
本实施例中,所述温判有物提示装置包括一壳体,所述壳体内设置一电路板,所述电路板上设置有感温模块10、控制模块20、夹角测距模块30、电源模块40和蓝牙模块50;控制模块20连接感温模块10、夹角测距模块30和蓝牙模块50;电源模块40连接感温模块10、控制模块20、夹角测距模块30和蓝牙模块50;控制模块20外接蜂鸣模块和左右警示灯模块、电源模块40外接车辆电瓶,蓝牙模块50与移动终端通讯连接。所述外接,即温判有物提示装置引出信号线连接车辆内部对应的器件。所述蓝牙模块50接收移动终端输出的模式指令并传输给控制模块20来设置提示方式,所述感温模块10检测车辆左右侧的第一预设范围内各个分区的温度并输出对应的温度值;夹角测距模块30实时发射信号并检测是否有反射信号,收到反射信号时输出报警信号给控 制模块20;控制模块20根据各个分区的温度值计算平均值,判断任一分区的温度值比平均值高出第一阈值(或相邻至少2个分区的温度值比平均值高出第二阈值)时,或接收到报警信号时,输出相应的控制信号给左右警示灯模块和蜂鸣模块,以进行对应提示方式的提示。所述电源模块40将车辆的电瓶电压转换为供电电压+3.3V来供电。控制模块20还可将各个分区的温度值通过蓝牙模块50发送至移动终端显示。
其中,所述温判有物提示装置主要安装在车辆上,如图2所示,安装在左后视镜1的上方或下方,右后视镜3的上方或下方,或车顶2。则温判有物提示装置引出7条信号线与车辆内部的器件相连,第一信号线为地线,与车辆电瓶的负极BAT-连接;第二信号线为电源线,与车辆电瓶的正极BAT+连接;第三信号线为左转检测线,与左转灯的正极LTL+连接或被拉高;第四信号线为右转检测线,与右转灯的正极RTL+连接或被拉高;第五信号线为左警示控制线,第六信号线为右警示控制线,均与左右警示灯模块连接;第七信号线为提示线,与蜂鸣模块连接。
当温判有物提示装置安装在车顶2时,可在安装时直接将左转检测线和右转检测线均与车辆电瓶的正极连接或通过控制模块20将两条检测线上拉为高电平;这样无论车辆是否左右转,只要左右两侧有车就提示。若将左转检测线连接左转灯的正极LTL+,右转检测线连接右转灯的正极RTL+,当车主打左转灯(左转灯的正极LTL+有电),控制模块20检测左转检测线为高电平,此时只判断车辆左侧范围的温度值并进行是否有物的提示;当车主打右转灯,控制模块20检测右转检测线为高电平,此时只判断车辆右侧范围的温度值并进行是否有物的提示。
在具体实施时,所述温判有物提示装置可根据安装位置设置为3种型号,即左侧专用、右侧专用和两侧共享。这样左侧专用的温判有物提示装置可在生产时去掉右转检测线和右警示控制线,同理,右侧专用的温判有物提示装置可在生产时去掉左转检测线和左警示控制线;这样可减少布线,节约成本。
本实施例,所述移动终端内预先安装对应的温判APP,可设置提示方式。所述提示方式包括三种:第一种是静音模式,即用户通过移动终端发出静音 模式指令,蓝牙模块50接收后传输给控制模块20,控制模块20根据静音模式指令将提示线断开,不接蜂鸣模块就不会发声报警;第二种是声光报警模式(默认),移动终端发出提示模式指令,控制模块20将左转检测线、右转检测线均拉高,左侧或右侧检测有物时,点亮对应的警示灯并使蜂鸣器发声报警;第三种是变道检测模式,此时移动终端发出变道模式指令,控制模块20将左转检测线连接左转灯的正极LTL+,右转检测线连接右转灯的正极RTL+,这样只有在打左转灯号且左侧有车时,警示灯亮并嘀嘀音(蜂鸣器发出的)提示,或在打右转灯号且右侧车时,警示灯亮及嘀嘀音提示。
请一并参阅图3,本实施例中,所述感温模块10包括矩阵感温晶片U1、第一电阻R1和第二电阻R2;所述矩阵感温晶片U1的第1脚连接供电端(由电源模块产生,提供3.3V供电电压)、第一电阻R1的一端和第二电阻R2的一端,矩阵感温晶片U1的第2脚连接第二电阻R2的另一端和控制模块20,矩阵感温晶片U1的第3脚连接第一电阻R1的另一端和控制模块20,矩阵感温晶片U1的第4脚和第5脚均连接控制模块20,矩阵感温晶片U1的第6脚接地。
所述矩阵感温晶片U1的型号优选为AMG8833,其为8×8矩形并排的热电堆阵列红外传感器(Grid-EYE),其在一个8×8网格式布局内含有64个热电堆元件,能够在不接触被测物体的前提下探测物体(静止和运动,非活体目标和人体目标)表面的温度。每一个热电堆元件都透过菲尼尔滤镜聚焦,能读到7米远范围内的最高温;将横向观察范围分成八区,总角度约120度,则每个区为15度左右,长度是87.5厘米左右(700/8=87.5);纵向观察范围分成八区或四区,每个区可测长度为7米远、高度2米;每个纵向感应高度为25厘米或50厘米,一个热电堆元件的感应范围87.5×50厘米,因此能分辨出所探测的物体是人还是车。
请一并参阅图4,所述控制模块20包括微处理器U2、晶振Y1、第一电容C1、第二电容C2和第三电容C3;所述微处理器U2的PB6脚连接左转检测线(默认连接左转灯的正极LTL+),微处理器U2的PB7脚连接右转检测线(默认连接右转灯的正极RTL+),微处理器U2的AD4/PA1脚和INT0/PA0脚均连接夹角测距模块30,微处理器U2的VCC脚连接供电端和第一电容C1的一端,微处理器 U2的VSS脚连接第一电容C1的另一端和地,微处理器U2的FXO/PA3脚连接第二电容C2的一端和晶振Y1的一端,微处理器U2的FXI/PA4脚连接第三电容C3的一端和晶振Y1的另一端,第二电容C2的另一端连接第三电容C3的另一端和地;微处理器U2的PG4脚、PG5脚和PF1脚均连接蓝牙模块50;微处理器U2的PB1脚、PB2脚、PB3脚、PF4脚与矩阵感温晶片U1的第5脚、第4脚、第3脚、第4脚一对一连接;微处理器U2的PB0脚通过提示线外接蜂鸣模块,微处理器U2的PD7脚通过左警示控制线外接左右警示灯模块,微处理器U2的PD6脚通过右警示控制线外接左右警示灯模块。
其中,所述微处理器U2的型号优选为为TM57FLA80。所述晶振Y1用于提供微处理器U2工作的时钟,电源模块40提供+3.3V的供电电压给微处理器U2供电。所述微处理器U2每隔预设时间(可每隔1秒一次、或1/10秒一次,可根据实际需求设置)通过控制信号AD_SELECT发送请求指令给矩阵感温晶片U1。矩阵感温晶片U1接收到请求指令后开始计算每个区内的温度值,计算完成后输出中断信号INT给微处理器U2,微处理器U2再通过串列控制信号(SDA、SCL)读取矩阵感温晶片U1的温度值。微处理器U2根据各个分区的温度值计算平均值来作为环境温度,当微处理器U2判断任一分区的温度值比平均值高出第一阈值(如冬天可设为10度,或为40度),或相邻至少2个分区的温度值比平均值高出5度时,或接收到夹角测距模块输出的报警信号时,则判断左右侧有物(车辆或人);微处理器U2的PB0脚输出高电平的蜂鸣信号BUZZER时,蜂鸣模块内蜂鸣器形成到地通路,蜂鸣器发声报警;微处理器U2的PD6脚、PD7脚输出高电平的右警示信号RWL-、左警示信号LWL-时,左右警示灯模块内对应的左右警示灯导通发光(可发红光)。
在具体实施时,微处理器U2可通过控制信号AD_SELECT发送配置指令给矩阵感温晶片U1,用于控制矩阵感温晶片U1将每个区内的最高温值、或最低温值、或计算平均值后作为温度值反馈给微处理器U2。此处以最高温值作为温度值。
所述微处理器U2的PF1脚输出使能信号BT P0.0控制蓝牙模块工作,微处理器U2的PG4脚接收蓝牙模块传输的模式指令来配置提示方式,例如,静音 模式,微处理器U2可将其PB0脚悬空,蜂鸣器的正负极无法形成回路就不会发声。声光报警模式,微处理器U2直接将其左转检测线、右转检测线与电源模块40输出的3.3V电压连接而拉高。变道检测模式,微处理器U2保持其PB6脚的左转检测线连接左转灯的正极LTL+,其PB7脚的右转检测线连接右转灯的正极RTL+的连接状态。
所述微处理器U2的PG5脚将各个分区的温度值发送给蓝牙模块,通过蓝牙模块发送至移动终端显示,移动终端可以绿黄红颜色来区分温度高低,这样移动终端可用作环境观察,在户外可当作免光源热感摄像机使用。也可将灯光、蜂鸣状态发送至移动终端显示,如微处理器U2的PB0脚输出高电平控制蜂鸣模块导通发声时,微处理器U2的PG5脚发出发声提示的信息通过蓝牙模块发送给移动终端。微处理器U2的AD4/PA1脚输出询问信号Trig给夹角测距模块30以启动夹角测距模块30的进行障碍物检测。夹角测距模块30检测有障碍物时,返回报警信号Echo至微处理器U2的INT0/PA0脚,若无障碍物则无信号返回。微处理器U2根据报警信号Echo即可进行相应的报警控制。
请一并参阅图5,所述夹角测距模块30包括超声波测距芯片U3(型号优选为SRF05,具体为HY-SRF05超声波模块),所述超声波测距芯片U3的第1脚连接供电端,超声波测距芯片U3的第2脚连接微处理器U2的AD4/PA1脚,超声波测距芯片U3的第3脚连接微处理器U2的INT0/PA0脚,超声波测距芯片U3的第5脚接地。
为了避免障碍物与环境温度相差较小,感应不明显,通过增加超声波测距芯片U3,其在与车身呈15度夹角、5米长的范围内实时地发射信号(一种超声波)来判断是否有障碍物,有则信号被返回反射信号,根据反射信号输出对应的报警信号给微处理器U2。
请一并参阅图6,所述电源模块40包括电压稳压芯片(型号优选为HT7533)U4、第四电容C4和第五电容C5;所述电压稳压芯片U4的Vin脚连接车辆电瓶的正极BAT+(+12V)和第四电容C4的一端,电压稳压芯片U4的GND脚接地(车辆电瓶的负极BAT-也接地),电压稳压芯片U4的Vout脚连接供电端和第五电容C5的一端,第四电容C4的另一端和第五电容C5的另一端均接地;电压稳 压芯片U4的Vout脚即是供电端,连接相应的模块并对其供电。
所述电压稳压芯片U4将车辆电瓶的电压转换为3.3V的供电电压来供电。第四电容C4和第五电容C5起到滤波的作用。

请一并参阅图8,所述左右警示灯模块包括左警示灯D1、右警示灯D2、第一三极管Q1、第二三极管Q2、第三电阻R3、第四电阻R4、第五电阻R5和第六电阻R6;所述左警示灯D1的正极通过第三电阻R3连接车辆电瓶的正极,左警示灯D1的负极连接第一三极管Q1的集电极,第一三极管Q1的基极通过第五电阻R5连接左警示控制线(对应连接微处理器U2的PD7脚),第一三极管Q1的发射极接地,右警示灯D2的正极通过第四电阻R4连接车辆电瓶的正极,右警示灯D2的负极连接第二三极管Q2的集电极,第二三极管Q2的基极通过第六电阻R6连接右警示控制线(对应连接微处理器U2的PD6脚),第二三极管Q2的发射极接地。
其中,第一三极管Q1和第二三极管Q2均为NPN三极管,R3~R6起到限流保护的作用,D1为左警示灯,D2为右警示灯。左警示控制线传输的左警示信号LWL-为高电平时,Q1导通,D1的负极被拉到地形成回路,D1发光;同理,右警示控制线传输的右警示信号RWL-为高电平时,Q2导通,D2的负极被拉到地形成回路,D2发光。
请一并参阅图9,所述蜂鸣模块包括蜂鸣器BUZ、第三三极管Q3和第七电阻R7;所述蜂鸣器BUZ的正极连接车辆电瓶的正极,蜂鸣器BUZ的负极连接 第三三极管Q3的集电极,第三三极管Q3的基极通过第七电阻R7连接提示线(对应连接微处理器U2的PB0脚),第三三极管Q3的发射极接地。
其中,第三三极管Q3为NPN三极管,R7起到限流保护的作用。当提示线上传输的蜂鸣信号BUZZER为高电平时,Q3导通,蜂鸣器BUZ形成到地回路即可发出声音。蜂鸣信号BUZZER为脉冲信号,其占空比决定了蜂鸣器BUZ声音的大小。
综上所述,本发明提供的温判有物提示装置及车载系统,能通过温度对车辆左右两侧的障碍物进行检测并进行对应的提示,结合同时有死角(与车身呈15度夹角、5米长的范围内)检测,确保车辆左右侧有物判断的准确性,与现有的左右后视镜相比,本发明能避免阳光和远光灯的强光反视,提高行车安全性,还不会受白天黑夜的影响,左右变道时能及时发声闪灯提示,无需驾驶人分心,在左右侧的安全距离范围内完全无车时,声光方式提示停止,再转换车道,从而大幅度降低与左右车道的物体相撞的风险。
