图1为本申请实施例涉及的应用场景示意图,参照图1所示,该固件升级系统包括雷达系统100和终端设备200,雷达系统100与终端设备200通信连接。雷达系统100包括:控制系统10和N个雷达,N个雷达分布在不同的位置,用于检测不同位置/方向的物体信息,控制系统10根据N个雷达所检测物体信息进行综合处理,从而了解周围环境的物体信息。例如在汽车上布置这种分布式雷达系统后,通过N个雷达来探测汽车周围不同方位的物体信息,从而了解汽车周围环境的物体信息。
控制系统10可以包括一个或多个处理器,用于接收雷达1-N发送的数据,并对数据进行处理,以及控制雷达1-N以及其他模块的工作。控制系统10连接至N个雷达接口,雷达可通过传输线缆20连接至雷达接口,从而将雷达接入控制系统10中,以便控制系统10接收雷达的数据,并对雷达进行控制。
雷达可以为激光雷达、超声波雷达、毫米波雷达或其它测距装置或距离探测装置。优选地,在本实施例中,雷达系统100为激光雷达系统。
示例性的,如图2所示,上述雷达可以包括:发射电路11、接收电路12、采样电路13、运算电路14和控制电路15。其中,发射电路11可以发射光脉冲序列(例如激光脉冲序列)。接收电路12可以接收经过被探测物反射的光脉冲序列,并对该光脉冲序列进行光电转换,以得到电信号,再对电信号进行处理之后可以输出给采样电路13。采样电路13可以对电信号进行采样,以获取采样结果。运算电路14可以基于采样电路13的采样结果,以确定雷达与被探测物之间的距离。控制电路15可以实现对上述各电路的控制,例如,可以控制各个电路的工作时间和/或对各个电路进行参数设置等。

可选的,若本申请实施例的雷达系统安装在无人机上,则上述终端设备可以为无人机的控制终端。
本申请实施例涉及的固件升级方法,当雷达系统中的一个或多个雷达进行固件涉及时,终端设备将升级文件发送给雷达系统中的控制系统,控制系统使用将该升级文件升级对应的雷达。
需要说明的是,本申请实施例涉及对雷达进行固件升级,具体是对该雷达中的一个或多个模块进行固件升级。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
图3为本申请实施例提供的固件升级方法的流程图,如图3所示,本申请实施例的方法可以包括:
S101、终端设备生成第一升级文件包,其中,所述第一升级文件包中包括至少一个第二升级文件包,至少一个第二升级文件包与雷达系统中的至少一个雷达一一对应。
具体的,在固件升级过程中,不同雷达对应的第二升级文件包不同,即一个雷达对应一个第二升级文件包,当对雷达系统中的一个或多个雷达进行固件升级时,终端设备获取一个或多个雷达的第二升级文件包。其中终端设备获取一个或多个雷达的第二升级文件包的方式可以不同,例如,终端设备获取一个或多个雷达的第二升级文件,接着对一个或多个雷达的第二升级文件进行处理(例如打包处理),生成一个或多个雷达的第二升级文件包。再例如,终端设备直接获取用户输入的一个或多个雷达的第二升级文件包,或者终端设备从其他的设备上获取一个或多个雷达的第二升级文件包。
终端设备获取一个或多个雷达的第二升级文件包后,对一个或多个雷达的第二升级文件包进行处理(例如打包处理),生成一个升级文件包,即生成第一升级文件包。
本步骤,通过将一个或多个雷达的第二升级文件包进行处理,生成一个 第一升级文件包,这样方便终端设备将该第一升级文件包的传输。且传输次数少,可以避免升级文件在传输过程中被篡改的风险,从而提高了雷达系统固件升级的可靠性和成功率。
S102、终端设备将所述第一升级文件包发送给所述雷达系统。
该终端设备与雷达系统通信连接,两者之间可以相互发送数据,可选的,终端设备与雷达系统有线连接,例如需要对雷达系统进行固件升级时,将终端设备连接到雷达系统上,用于向雷达系统发送第一升级文件包。可选的,终端设备与雷达系统无线连接,例如终端设备与雷达系统通过wifi、蓝牙等无线通信连接。
这样,终端设备根据上述步骤生成第一升级文件包后,将该第一升级文件包发送给雷达系统,以使雷达系统根据该第一升级文件包进行固件升级。
S103、雷达系统接收终端设备发送的第一升级文件包后,对所述第一升级文件包进行解析,获得至少一个所述第二升级文件包。
由上述可知,雷达系统包括控制系统,该控制系统包括一个或多个处理器,可选的,该雷达系统还包括通信模块,该通信模块接收终端设备发送的第一升级文件包。该通信模块将接收到的第一升级文件包发送给控制系统,控制系统对该第一升级文件包进行解析,例如对该第一升级文件包进行解压处理,获得该第一升级文件包所携带的至少一个第二升级文件包。
S104、雷达系统根据至少一个所述第二升级文件包,对至少一个所述雷达分别进行固件升级。
雷达系统解析至少一个第二升级文件包后,使用该至少一个第二升级文件包,对该至少一个第二升级包对应的至少一个雷达分别进行固件升级。例如,上述第一升级文件包携带3个第二升级文件包,分别为第二升级文件包1、第二升级文件包2和第二升级文件包3,其中,第二升级文件包1对应雷达1、第二升级文件包2对应雷达2,第二升级文件包3对应雷达3,这样,雷达系统可以使用第二升级文件包1对雷达1进行固件升级,使用第二升级文件包2对雷达2进行固件升级,使用第二升级文件包3对雷达3进行固件升级。
需要说明的是,上述使用第二升级文件包对各雷达进行升级是对雷达中各模块进行升级,例如第二升级文件包1包括雷达1中运算电路的升级文件, 则可以使用第二升级文件包1对雷达1中运算电路进行固件升级。
在一种示例中,雷达系统根据至少一个第二升级文件包,对至少一个雷达分别进行固件升级,可以是:雷达系统将至少一个第二升级文件包分发给对应的雷达,以使雷达根据接收到的第二升级文件包进行固件升级,例如雷达解析接收到的第二升级文件包,从中获取第二升级文件,使用该第二升级文件对对应的模块进行升级。
在另一种示例中,雷达系统根据至少一个第二升级文件包,对至少一个雷达分别进行固件升级,可以是:雷达系统对至少一个第二升级文件包中的每个第二升级文件包进行解析,获得至少一个第二升级文件,接着,将至少一个第二升级文件发送给对应的雷达,以使雷达根据接收到的第二升级文件进行固件升级。
可选的,上述S104还可以包括其他的实现方式,本申请实施例对此不做限制。
本申请实施例提供的固件升级方法,通过终端设备生成第一升级文件包,该第一升级文件包中包括至少一个第二升级文件包,而至少一个第二升级文件包与雷达系统中的至少一个雷达一一对应;接着,终端设备将该第一升级文件包发送给雷达系统。雷达系统对该第一升级文件包进行解析,获得至少一个第二升级文件包,并使用该至少一个第二升级文件包,对至少一个雷达分别进行固件升级。这样,通过将多个雷达的第二升级文件携带在一个第一升级文件包中,一次发送给雷达系统,可以有效减少终端设备与雷达系统之间的通信次数,进而降低了终端设备与雷达系统传输升级文件包的过程中升级文件包被篡改的几率,进而提高了雷达系统固件升级的可靠性和安全性。
图4为本申请实施例提供的固件升级方法的流程图,在上述实施例的基础上,如图4所示,本申请实施例的方法包括:
S201、终端设备按照预设的打包协议,对至少一个所述第二升级文件进行打包,生成所述第一升级文件包。
终端设备在生成第一升级文件包之前,先获得预设的打包协议,以及至少一个第二升级文件,至少一个第二升级文件与至少一个雷达一一对应。接着,终端设备根据预设的打包协议,对至少一个第二升级文件进行打包处理, 生成第一升级文件包。

其中,上述第一魔数用于对第一升级文件包进行标识说明。可选的,第一升级文件包的校验码可以为CRC(即循环冗余校验码),该CRC是一种数据传输检错功能,对数据进行多项式计算,并将得到的结果附在帧的后面,接收设备也执行类似算法,以保证第一升级文件包传输的正确性和完整性。
可选的,若第一升级文件包包括一个第二升级文件包时,则该第一升级文件包的版本信息可以与第二升级文件包的版本信息一致。
S202、终端设备根据预设的传输协议对所述第一升级文件包进行打包,获得第一数据包。
S203、终端设备将所述第一数据包发送给所述雷达系统。
上述S202与S203为上述S102的一种实现方式。
终端设备根据上述S101或S202的方法生成第一升级文件包后,将该第一升级文件包发送给雷达系统,此时,为了提高第一升级文件包的传输安全性和完整性,则在发送第一升级文件包时,使用预设的传输协议对该第一升 级文件包进行打包,生成第一数据包。
可选的,本申请实施例使用的预设的传输协议可以为已有的任意一种传输协议,例如,RTMP(Real Time Messaging Protocol,实时消息传输协议)协议、sproto协议等;在其他实施方式中,预设的传输协议也可以为用户自定义的传输协议,例如,用户可以基于用户通信协议进行自定义,通过SDK获取需要的数据,例如通过雷达系统获取的点云数据,以满足用户需求。
示例性的,如表1所示,上述生成的第一数据包包括:帧头、数据段和帧尾,其中数据段包括第一升级文件包。
表1
帧头 数据段 帧尾
可选的,上述第一数据包的帧头包括:第二魔数,该第二魔数用于对第一数据包进行标识说明。
可选的,上述第一数据包的帧头还包括:数据段的描述信息和/或第一数据包的帧头的校验码。其中,数据段的描述信息可以为对第一升级文件包的描述信息,例如包括第一升级文件包的版本信息、第一升级文件包的大小或第一升级文件包所包括的第二升级文件包的数量等信息。可选的,第一数据包的帧头的校验码可以为CRC,该CRC是一种数据传输检错功能,对数据进行多项式计算,并将得到的结果附在帧的后面,接收设备也执行类似算法,以保证第一数据包传输的正确性和完整性。
可选的,上述第一数据包的帧尾包括:数据段的描述信息和/或帧尾的校验码,其中,帧尾包括的数据段的描述信息可以与帧头包括的数据段的描述信息相同,或者,帧尾包括的校验码与帧头包括校验码相同。
由上述可知,上述第一数据包可以是:帧头包括数据段的描述信息,帧尾包括校验码;或者,帧头包括校验码,帧尾包括数据段的描述信息;或者,帧头包括数据段的描述信息和/或校验码,帧尾不包括数据段的描述信息和/或校验码;或者,帧头不包括数据段的描述信息和/或校验码,帧尾包括数据段的描述信息和/或校验码;或者,帧头和帧尾均包括数据段的描述信息和校验码。
本实施例根据预设的传输协议将第一升级文件包进行打包生成第一数据包,生成的第一数据包包括校验码,提高了第一数据包传输的正确性和完整 性,进而保证了第一数据包携带的第一升级文件包传输的正确性和完整性。这样,雷达系统使用正确和完整的第一升级文件包进行固件升级时,提高固件升级的可靠性。
S204、雷达系统对所述第一升级文件包进行解析,获得至少一个所述第二升级文件包。
上述S204的具体执行过程可以参照上述103的描述,在此不再赘述。
S205、雷达系统针对每个所述第二升级文件包,根据所述第二升级文件包的包头信息中的所述雷达的标识信息,确定与所述第二升级包对应的所述雷达。
S206、雷达系统根据所述第二升级文件包,对确定的所述雷达进行固件升级。
上述S205和S206为上述104的一种实现方式。
在该实现方式中,雷达系统接收到终端设备发送的第一数据包后,解析该第一数据包,获得其中携带的第一升级文件包,接着,对该第一升级文件包进行解析,获得该第一升级文件包携带的至少一个第二升级文件包。
若上述每个第二升级文件包的包头信息包括所述雷达的标识信息,这样,雷达系统可以根据每个第二升级文件包的包头信息所包括的雷达的标识信息,可以确定每个第二升级文件包对应的雷达。
接着,雷达系统使用各雷达对应的第二升级文件包来对各雷达进行固件升级。其中,雷达系统使用各雷达对应的第二升级文件包来对各雷达进行固件升级包括但不限于如下实现方式中。
在一种示例中,雷达系统将上述至少一个第二升级文件包进行解析,获得至少一个第二升级文件,接着,雷达系统将各第二升级文件分发给对应的雷达,以使雷达根据接收到的第二升级文件进行固件升级。可选的,雷达系统中的控制系统与各雷达连接,这样根据控制系统与各雷达已有的通信协议,控制系统将第二升级文件分发给雷达。可选的,控制系统根据上述预设的传输协议将第二升级文件分发给雷达,例如,控制系统根据表1所示的预设的传输协议,将第二升级文件进行打包,并将打包后的第二升级文件发送给对应的雷达。
在另一种示例中,雷达系统将第二升级文件包分发给对应的雷达,以使 雷达根据接收到的第二升级文件包进行固件升级。具体是,雷达系统对第二升级文件包不作处理,直接发送给对应的雷达,雷达接收到第二升级文件包后,对该第二升级文件包进行解析,获得第二升级文件,并使用解析获得的第二升级文件进行固件升级。
可选的,上述雷达系统将第二升级文件包分发给对应的雷达可以包括步骤A和步骤B:
步骤A、雷达系统根据预设的传输协议对所述第二升级文件包进行打包,获得第二数据包;

该实现方式中,雷达系统获得第二升级文件包后,使用如表1所示的预设的传输协议将该第二升级文件包发送给对应的雷达,具体是,雷达系统根据预设的传输协议对第二升级文件包进行打包,获得第二数据包,该第二数据包包括帧头、数据段和帧尾,其中,帧头包括:第三魔数、数据段的描述信息和/或帧头的校验码等,帧尾包括:数据段的描述信息和/或帧尾的校验码等。接着,雷达系统将上述生成的第二数据包分发给对应的雷达。雷达获得第二数据包后,对该第二数据包进行解析,获得第二升级文件包,并对第二升级文件包进行解析,获得第二升级文件,并使用该第二升级文件进行固件升级。当然,雷达系统获得第二升级文件包后,也可以使用其他预设的传输协议将该第二升级文件包发送给对应的雷达,在此不作限定。
进一步地,在一种实施方式中,雷达系统可以统计各个雷达的固件升级进度和升级情况,并实时反馈到终端设备。例如,雷达系统统计各雷达的固件升级进度、是否升级失败、升级失败的固件数量、升级失败的固件的版本信息、以及固件升级失败的原因等升级状态信息,并将这些升级状态信息实时反馈给终端设备,以便终端设备根据升级状态信息及时掌握雷达系统的固件升级情况,并采集相应的措施。例如终端设备根据雷达系统反馈的固件升级状态信息,分析固件升级失败的原因,或者,重新向雷达系统发送升级失败的固件对应的升级文件,以提高固件升级的成功率。
该实现方式中,雷达系统使用预设的传输协议将第二升级文件包进行打包后,再发送给对应的雷达,不仅丰富了雷达系统内部数据传输的方式,并且提高了第二升级文件包传输的安全性,进一步提高了固件升级的可靠性。
