Description

一种车辆信息的传输装置及方法
本申请要求在2015年10月21日提交中国专利局、申请号为201510694830.3、发明名称为“一种车辆信息的传输装置及方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及智能交通技术领域，尤其涉及一种车辆信息的传输装置及方法。
背景技术
特种车辆通常需要担负抢险、救援、维护国家或公共安全等特种勤务，在确保安全的前提下，不受行驶路线、行驶方向、行驶速度和信号灯的限制，其他车辆和行人应当让行。因此，对于特种车辆来说，行车路上的前车及时进行避让并保持路况畅通是和时间赛跑的根本保障。
现有的特殊车辆警示方法主要是使用警报器、标志灯具等等，这种警示方法传播距离有限，而且很容易受到遮挡、能见度、环境噪音等因素影响，大部分时候前车来不及做避让动作而导致特种车辆不得不减速或者变道，耽误宝贵的救援时间。

具体实施例
为使本发明实施例的目的、技术方案和优点更加清楚，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，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通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。
参考图1，示出了本发明实施例的一种车辆信息的传输装置实施例的结构框图，本发明实施例中的车辆上可以安装有的车载单元OBU。
需要说明的是，本发明实施例中的OBU(On board Unit，车载单元)是安装在车辆上，采用DSRC(Dedicated Short Range Communication，专用短程通信技术)，能够与其他车辆的车载单元OBU或者其他路边架设的设备进行通讯的微波装置。例如，在ETC(Electronic Toll Collection，电子不停车收费系统)中，将车载单元OBU放在车辆上，与路边架设的RSU(Road Side Unit，路侧单元)，相互之间通过微波进行通讯，从而实现车辆身份识别，电子扣分等功能的设备。
专用短程通信技术DSRC是一种高效的无线通信技术，它可以实现在特定小区域内(通常为数十米)对高速运动下的移动目标的识别和双向通信，例如车辆的“车-路”、“车-车”双向通信，实时传输图像、语音和数据信息，实现车辆和道路有机的连接。在实际的应用中，建立车-路之间的连接，可以根据路况情况实时提供优化的驾驶路线，缓解交通压力，建立车-车之间 的连接，可以提示车与车之间的安全距离，提前预警通行前方的事故，提高交通安全的系数。通过专用短程通信技术DSRC在智能交通中的应用，不断改善和提高了人们的交通出行效率。
当然，在本发明实施例中并不仅仅局限于使用专用短程通信技术DSRC来实现车辆上信息的传输，也可根据实际情况跟实际需求选择不同的通信协议，本发明实施例对此不加以限制。
在本发明实施例中，车辆上安装的车载单元OBU具体可以包括导航模块101，信息整合模块102，通信处理模块103，以及无线发射模块104，各个模块的功能描述具体如下所示：
导航模块101，用于获取当前车辆的车辆行驶信息；
在本发明的一种优选实施例中，所述导航模块101可以包括如下子模块：
车辆行驶信息获取子模块，用于通过全球定位系统GPS、全球导航卫星系统GNSS、重力传感器G-sensor、和/或控制器局域网络CAN获取当前车辆的位置信息，车速信息，路线信息和/或目的地信息。
在本发明实施例中的导航模块101除了可以用于常用的路线导航外，更主要的功能是获取车辆的当前位置，车速，路线和目的地等信息。
在本发明的一种优选示例中，可以采用GPS(Global Positioning System，全球定位系统)或者GNSS全球导航卫星系统(Global Navigation Satellite System)来实现车辆的定位，可以用于获取当前车辆的位置。
在本发明的一种优选示例中，可以采用G-sensor(Gravity-sensor，重力传感器)来获取当前车辆的车速。利用重力传感器G-sensor能够感知到加速力的变化，加速力就是当物体在加速过程中作用在物体上的力，比如晃动、跌落、上升、下降等各种移动变化都能被重力传感器G-sensor转化为电信号，然后通过微处理器的计算分析后，就能够获得所需的信息，比如当前车辆的车速。
在本发明的一种优选示例中，目的地位置可以由用户设定或者输入，可以通过车辆的CAN(Controller Area Network，控制器局域网络)，即目前应用最广泛的现场总线之一，去读取用户设定或输入的目的地位置等其他信息。
需要说明的是，在本发明实施例中的车辆行驶信息的获取方法，包括但 不限于上述的采用GPS/GNSS、g-sensor、从车辆的CAN总线读取等方法，还可以通过云服务器来实现数据的获取或传输。例如，通过云服务器获取车辆行驶数据，并且还可以通过云服务器来传输数据，本发明实施例对此不加以限制。
信息整合模块102，用于接收车辆警示信息，并依据所述车辆警示信息和所述车辆行驶信息生成整合警示信息；
在具体实现中，信息整合模块主要用于整合警示信息，信息整合模块可以将输入信息整合在一起，即形成整合警示信息。具体地，信息整合模块中输入信息可以包括两部分，一部分输入信息可以由用户输入设定，可以是语音输入，也可以是手动输入。例如，用户可以输入“XX小区发生火灾，请右侧变道让开左侧车道”等信息作为警示语句；另外一部分输入信息可以由导航模块提供，其中至少应该包括当前车辆的位置、车速、路线和目的地这些信息。
当所有输入信息经由信息整合模块整合完成，形成整合警示信息后，将输出给通信处理模块进行下一步的处理。
通信处理模块103，用于将所述整合警示信息按照预设格式进行封装；
在本发明的一种优选实施例中，所述车载单元OBU可以支持专用短程通信技术DSRC，所述通信处理模块103可以包括如下子模块：
DSRC数据封装子模块，用于按照所述专用短程通信技术DSRC针对整合警示信息进行封装。
在本发明实施例中，将整合警示信息通过通信处理模块经过封装，以将警示内容转换成数字信息，以符合无线发射模块的要求。
在本发明的一种优选示例中，可以按照专用短程通信技术DSRC的技术规格对于整合警示信息进行封装，封装过程严格遵照专用短程通信技术DSRC规定的数据格式，由专用短程通信技术DSRC的协议栈完成。
简单的说来，就是将源数据，例如整合后的整合警示数据经过一系列的格式变换(也就是封装)，在格式变换的过程中，会增加由专用短程通信技术DSRC协议规定的固定格式的报头、报尾等，其中在特定的位置包含了特定含义。例如，某个字节byte的某个位bit代表某个功能使能位，0表示功能关闭，1代表功能开启等，最终形成可以传输出去的报文，并交由硬件， 例如本发明实施例中的无线发射模块进行传输。
无线发射模块104，用于将所述封装后的整合警示信息传输到其他车辆上。
在本发明的一种优选实施例中，所述无线发射模块104可以包括如下子模块：
整合警示信息发送子模块，用于将所述封装后的整合警示信息按照专用短程通信技术DSRC所述传输到其他支持专用短程通信技术DSRC的车辆上。
在具体实现中，无线发射模块包括RF(Radio Frequency，射频)发射芯片、发射天线等部分，无线发射模块支持专用短程通信技术DSRC，可实现空旷环境达1000m、城市密集环境达300m的无线通信距离，且不受辐射范围内设觉死角、能见度、周围噪音等影响。
在本发明实施例中，当无线发射模块接收到按照专用短程通信技术DSRC封装后的整合警示信息时，就可以周期性地将利用专用短程通信技术DSRC将该整合警示信息传输给其他支持专用短程通信技术DSRC的车辆上。
在本发明的一种优选实施例中，所述的装置还可以包括如下模块：
供电模块105，用于为所述导航模块、信息整合模块、通信处理模块以及无线发射模块供电；其中，所述供电为采用蓄电池和/或车载电源进行供电。
在具体实现中，供电模块中可以包括蓄电池、电线、开关、接插件、变压器等等其他器件，供电模块用于给车载单元OBU提供工作所需要的电能。
在本发明的一种优选示例中，还可以将整合警示信息发送给路测单元RSU或者路上架设的其他单元，在一定的时间范围内，如果有车辆经过该路测单元RSU或者路上架设的其他单元，那么路测单元RSU或者路上架设的其他单元会发送警示信息给该车辆，提醒前方有需避让的车辆，若无紧急事件，可适当减速或者改变车道。
应用本发明实施例，可以当某一车辆需要传输数据给其他车辆时，利用车辆上安装的车载单元OBU进行无线通信，将获取到的车辆行驶信息和车辆警示信息先整合为整合警示信息，然后再封装为能够在车载单元OBU中进行传输的整合警示信息，以传输给其他的车辆。由于本发明实施例中的车 辆通过车载单元OBU来传输车辆信息，统一采用固定的通信协议，例如专用短程通信技术DSRC进行通信，因此无需预先进行通信连接，能够提升车辆信息的传输效率。
本发明实施例可应用于担负特种勤务的特种车辆，比如消防车，救护车，警车，工程车，军事监理车等等。当特种车辆在行驶时，可以通过特种车辆上车载单元OBU传输数据给路上的其他车辆，从而解决警报器、标志灯具等预警工具的警示距离短、易受环境影响的不足，能够使得其他及时接收到车辆信息，因此其他有足够的时间进行避让等反应，有效保证道路的畅通。
由此可以看出，本发明实施例可应用于流动的车辆中，被应用的车辆可被认为是一运动的信息传输设备，即在运动的过程中实时将道路情况发送至其他车辆，以使其他车辆及时地根据道路情况调整驾驶反应、运行路线。
现有趋势是，专用短程通信技术DSRC将是一种流行的用于车辆之间通信的协议，研究结果表明，将专用短程通信技术DSRC应用于车辆安全相关领域，可以减少90％的汽车伤亡率，将来可能会由法律法规强制要求车辆装载支持专用短程通信技术DSRC的车载单元OBU或者其他车载设备，那么应用本发明实施例的车辆信息的传输装置可以更好地通知其他车辆诸如紧急避让等信息，前景良好。
