参照图1，提出本发明的车载控制系统的数据处理方法一实施例，所述车载控制系统包括主控处理器，所述方法包括以下步骤：
S11、主控处理器将接收到的数据添加到对应的优先级队列中。
S12、主控处理器按照优先级从高到低的顺序依次处理各优先级队列中的数据。
本发明实施例的车载控制系统的数据处理方法，主要应用于车载控制系统，当然也可以应用于其它系统或设备，如终端设备、服务器等。本发明实施例的车载控制系统可以基于安卓(Android)系统，也可以基于其它系统，本发明对此不做限定。
本发明实施例所述的优先级队列，是指具有不同优先级的队列。优先级队列至少有两个，如包括高优先级队列和低优先级队列共两个优先级队列，或者包括高优先级队列、中优先级队列和低优先级队列共三个优先级队列，或者包括第一优先级队列、第二优先级队列、第三优先级队列、第四优先级队列......共多个优先级队列，等等。
步骤S11中，主控处理器接收到数据后，立即对该数据进行分类，将该数据添加到对应的优先级队列中。本发明实施例中，所述优先级队列为先入先出(First Input First Output，FIFO)队列。
可选地，主控处理器接收的数据包括车载信息。此时，车载控制系统还包括微处理器，步骤S11之前还包括：微处理器获取车载信息，对车载信息进行处理并形成数据，并向主控处理器传输该数据。主控处理器接收到数据后，立即对该数据进行分类，将该数据添加到对应的优先级队列中。其中，车载信息包括倒车信息、自适应巡航控制(Adaptive Cruise Control，ACC)信息、胎压信息、空 调状态信息(包括空调温度、风力、开关等信息)、油耗信息、FM频率信息、开/关(ON/OFF)信息、串行总线系统(ControLLer Area Net-work Bus，CANBus)信息等。
可选地，主控处理器接收的数据包括用户的操作指令。此时，步骤S11之前还包括：主控处理器接收用户的操作指令，对操作指令进行处理并形成数据。然后，主控处理器将该数据添加到对应的优先级队列中。所述操作指令包括空调操作指令、收音机操作指令、多媒体操作指令等。
在某些实施例中，车载控制系统包括至少两个通信接口，控处理器与微处理器通过通信接口传输数据，其中，至少两个通信接口分别具有不同的优先级信息。此时，当主控处理器接收的数据为车载信息形成的数据时，主控处理器获取通信接口的优先级信息，根据通信接口的优先级信息将微控制单元传输的数据添加到对应的优先级队列中。
例如，主控处理器接收到数据后，首先获取接收该数据的通信接口的优先级信息，然后根据通信接口的优先级信息将数据添加到对应的优先级队列中，即：将优先级高的通信接口接收的数据添加到高优先级队列中，将优先级低的通信接口接收的数据添加到低优先级队列中。
举例而言：
如图2所示，主控处理器与微处理器通过两个通用异步收发传输器(Universal Asynchronous Receiver/Transmitter，UART)串口进行通讯，两个UART串口分别为UART串口1和UART串口2，二者之间传输的数据为UART数据。定义UART串口1的优先级高于UART串口2的优先级，且UART串口1用来传输传送紧急的和安全相关的重要数据，如ACC信息、倒车信息、胎压信息等数据；UART串口2用来传输常规数据，如空调状态信息、油耗信息、FM频率信息等数据。
如图3所示，当主控处理器的UART串口1接收到ACC信息、倒车信息、胎压信息等数据时，则添加到高优先级队列中；当主控处理器的UART串口2接收到空调状态信息、油耗信息、FM频率信息等数据时，则添加到低优先级队列中。
在其它实施例中，可以预先定义数据的优先级，当接收到数据后，首先获取数据的优先级信息，然后根据数据的优先级信息将该数据添加到对应的优先级队 列中，即：将优先级高的数据添加到高优先级队列中，将优先级低的数据添加到低优先级队列中。
可选地，可以预先设置数据与优先级信息对照库，主控处理器根据接收的数据在数据与优先级信息对照库中查询对应的优先级信息。例如：倒车信息和ACC信息对应高优先级，胎压信息和速度信息对应中优先级，空调状态信息、油耗信息和FM频率信息对应低优先级。
可选地，可以在数据中添加优先级标识，主控处理器解析接收到的数据中的优先级标识，就能获取该数据的优先级信息。例如：优先级标识“1”代表高优先级，优先级标识“0”代表低优先级。
举例而言：
如图4所示，主控处理器中预设了数据与优先级信息对照库，其中，倒车信息和ACC信息对应高优先级，胎压信息、速度信息对应中优先级，空调温度信息、油耗信息和FM频率信息对应低优先级。
如图5所示，当主控处理器接收到ACC信息、倒车信息时，则添加到高优先级队列中；当主控处理器接收到胎压信息和速度信息时，则添加到中优先级队列中；当接收到空调温度信息、油耗信息和FM频率信息时，则添加到低优先级队列中。
进一步地，对同一优先级队列中的数据，主控处理器也可以对其进行排序。在一些实施例中，主控处理器可以对同一优先级队列中的数据按照数据的接收时间的先后顺序进行排序，即：先接收到数据排在前面，后接收到的数据排在后面。在另一些实施例中，主控处理器可以对同一优先级队列中的数据按照数据的优先级的高低顺序进行排序。
例如，对数据定义九个优先级，第一到第三优先级的数据添加到高优先级队列中，且按照第一、第二、第三优先级的顺序对其中的数据进行排序；第四到第六优先级的数据添加到中优先级队列中，且按照第四、第五、第六优先级的顺序对其中的数据进行排序；第七到第九优先级的数据添加到低优先级队列中，且按照第七、第八、第九优先级的顺序对其中的数据进行排序。从而，即使在同一优先级队列中，更加重要的数据也能够得到更优先的处理。
步骤12中，主控处理器优先处理优先级较高的优先级队列中的数据，当优先级较高的优先级队列中的数据处理完毕时，才处理优先级较低的优先级队列中的数据。并且在处理优先级较低的优先级队列中的数据过程中，当优先级较高的优先级队列中又添加了新数据时，则暂停处理优先级较低的优先级队列中的数据，优先处理优先级较高的优先级队列中添加的新数据，待处理完毕后再继续处理优先级较低的优先级队列中的数据。对于同一优先级队列中的数据，则按照排列顺序依次处理。
以优先级队列包括高优先级队列和低优先级队列为例，主控处理器判断高优先级队列中是否存在数据；若高优先级队列中存在数据，则中断处理低优先级队列中的数据，转而处理高优先级队列中的数据；接着判断高优先级队列中的数据是否处理完毕；若高优先级队列中的数据处理完毕，则恢复处理低优先级队列中的数据。
举例而言，如图5所示，主控处理器优先处理高优先级队列中的倒车信息和ACC信息，当处理完毕后再处理中优先级队列中的胎压信息和速度信息，当处理完毕后再处理低优先级队列中的空调温度信息、油耗信息和FM频率信息。在处理中优先级队列中的数据的过程中，当接收到倒车信息并添加到高优先级队列中时，则优先处理该倒车信息。在处理低优先级队列中的数据的过程中，当接收到ACC信息并添加到高优先级队列中时，则优先处理该ACC信息；当接收到胎压信息并添加到中优先级队列中时，则优先处理该胎压信息。
本发明实施例的数据处理方法，通过对接收到的数据进行分组，添加到不同的优先级队列中，并按照优先级从高到低的顺序依次处理各优先级队列中的数据，从而使得重要数据能够被优先处理，提高了重要数据处理的实时性，避免了重要数据的阻塞，提高了车辆的安全性，提升了用户体验。
参照图6，提出本发明的车载控制系统一实施例，所述系统包括主控处理器10。该主控处理器10如图7所示，包括添加模块11和处理模块12，其中，添加模块11用于将接收到的数据添加到对应的优先级队列中，处理模块12用于按照优先级从高到低的顺序依次处理各优先级队列中的数据。
本发明实施例的车载控制系统，可以基于安卓(Android)系统，也可以基于 其它系统，本发明对此不做限定。
本发明实施例所述的优先级队列，是指具有不同优先级的队列。本发明实施例中，所述优先级队列为FIFO队列。优先级队列至少有两个，如包括高优先级队列和低优先级队列共两个优先级队列，或者包括高优先级队列、中优先级队列和低优先级队列共三个优先级队列，或者包括第一优先级队列、第二优先级队列、第三优先级队列、第四优先级队列......共多个优先级队列，等等。
可选地，主控处理器10接收的数据包括车载信息，该车载信息包括倒车信息、自适应巡航控制(Adaptive Cruise Control，ACC)信息、胎压信息、空调状态信息(包括空调温度、风力、开关等信息)、油耗信息、FM频率信息、开/关(ON/OFF)信息、串行总线系统(ControLLer Area Net-work Bus，CANBus)信息等。
此时，车载控制系统还包括微处理器20，该微处理器20如图8所示，包括获取模块21、微处理模块2212和传输模块23，其中：获取模块21，用于获取车载信息；微处理模块2212，用于对车载信息进行处理并形成数据；传输模块23，用于向主控处理器10传输该数据。
可选地，主控处理器10接收的数据包括用户的操作指令，该操作指令包括空调操作指令、收音机操作指令、多媒体操作指令等。此时，如图9所示，主控处理器10还包括指令接收模块13和数据形成模块14，其中：指令接收模块13用于接收用户的操作指令，数据形成模块14用于对该操作指令进行处理并形成数据。
在某些实施例中，车载控制系统包括至少两个通信接口，控处理器与微处理器20通过通信接口传输数据，其中，至少两个通信接口分别具有不同的优先级信息。此时，添加模块11如图10所示，包括第一获取单元111和第一添加单元112。其中：第一获取单元111，用于当主控处理器10接收的数据为车载信息形成的数据时，获取接收该数据的通信接口的优先级信息；第一添加单元112，用于根据通信接口的优先级信息将数据添加到对应的优先级队列中，即：将优先级高的通信接口接收的数据添加到高优先级队列中，将优先级低的通信接口接收的数据添加到低优先级队列中。
举例而言：
如图2所示，主控处理器10与微处理器20通过两个通用异步收发传输器(Universal Asynchronous Receiver/Transmitter，UART)串口进行通讯，两个UART串口分别为UART串口1和UART串口2，二者之间传输的数据为UART数据。定义UART串口1的优先级高于UART串口2的优先级，且UART串口1用来传输传送紧急的和安全相关的重要数据，如ACC信息、倒车信息、胎压信息等数据；UART串口2用来传输常规数据，如空调状态信息、油耗信息、FM频率信息等数据。
如图3所示，当主控处理器10的UART串口1接收到ACC信息、倒车信息、胎压信息等数据时，添加模块1110则添加到高优先级队列中；当主控处理器10的UART串口2接收到空调状态信息、油耗信息、FM频率信息等数据时，添加模块1110则添加到低优先级队列中。
在其它实施例中，可以预先定义数据的优先级，此时，添加模块11如图11所示，包括第二获取单元113和第二添加单元114。其中：第二获取单元113，用于当接收到数据后，获取该数据的优先级信息；第二添加单元114，用于根据数据的优先级信息将该数据添加到对应的优先级队列中，即：将优先级高的数据添加到高优先级队列中，将优先级低的数据添加到低优先级队列中。
可选地，可以预先设置数据与优先级信息对照库，第二获取单元113包括查询子单元，其用于根据接收的数据在数据与优先级信息对照库中查询对应的优先级信息。例如：倒车信息和ACC信息对应高优先级，胎压信息和速度信息对应中优先级，空调状态信息、油耗信息和FM频率信息对应低优先级。
可选地，可以在数据中添加优先级标识，第二获取单元113包括解析子单元，其用于解析接收到的数据的优先级标识，获取该数据的优先级信息。例如：优先级标识“1”代表高优先级，优先级标识“0”代表低优先级。
举例而言：
如图4所示，主控处理器10中预设数据与优先级信息对照库，其中，倒车信息和ACC信息对应高优先级，胎压信息、速度信息对应中优先级，空调温度信息、油耗信息和FM频率信息对应低优先级。
如图5所示，当主控处理器10接收到ACC信息、倒车信息时，添加模块11则添加到高优先级队列中；当主控处理器10接收到胎压信息和速度信息时，添加模 块11则添加到中优先级队列中；当接收到空调温度信息、油耗信息和FM频率信息时，添加模块11则添加到低优先级队列中。
进一步地，如图12所示，添加模块11还包括排序单元115，该排序单元115用于对同一优先级队列中的数据进行排序。在一些实施例中，排序单元115可以对同一优先级队列中的数据按照数据的接收时间的先后顺序进行排序，即：先接收到数据排在前面，后接收到的数据排在后面。在另一些实施例中，排序单元115可以对同一优先级队列中的数据按照数据的优先级的高低顺序进行排序。
例如，对数据定义九个优先级，第二添加单元114将第一到第三优先级的数据添加到高优先级队列中，排序单元115按照第一、第二、第三优先级的顺序对其中的数据进行排序；第二添加单元114将第四到第六优先级的数据添加到中优先级队列中，排序单元115按照第四、第五、第六优先级的顺序对其中的数据进行排序；第二添加单元114将第七到第九优先级的数据添加到低优先级队列中，排序单元115按照第七、第八、第九优先级的顺序对其中的数据进行排序。从而，即使在同一优先级队列中，更加重要的数据也能够得到更优先的处理。
在其它实施例中，也可以在图10所示的添加模块11中增加排序单元115。
处理模块12优先处理优先级较高的优先级队列中的数据，当优先级较高的优先级队列中的数据处理完毕时，才处理优先级较低的优先级队列中的数据。并且在处理优先级较低的优先级队列中的数据过程中，当优先级较高的优先级队列中又添加了新数据时，则暂停处理优先级较低的优先级队列中的数据，优先处理优先级较高的优先级队列中添加的新数据，待处理完毕后再继续处理优先级较低的优先级队列中的数据。对于同一优先级队列中的数据，则按照排列顺序依次处理。
以优先级队列包括高优先级队列和低优先级队列为例，处理模块12如图13所示，包括第一判断单元31、中断单元32、第一执行单元33、第二判断单元34和第二执行单元35，其中：第一判断单元31，用于判断高优先级队列中是否存在数据；中断单元32，用于在第一判断单元31判定高优先级队列中有数据时，中断处理低优先级队列中的数据；第一执行单元33，用于当中断单元32中断处理低优先级队列中的数据时，处理高优先级队列中的数据；第二判断单元34，用于 判断高优先级队列中的数据是否处理完毕；第二执行单元35，用于在第二判断单元34判定高优先级队列中的数据处理完毕时，恢复处理低优先级队列中的数据。
举例而言，如图5所示，处理模块12优先处理高优先级队列中的倒车信息和ACC信息，当处理完毕后再处理中优先级队列中的胎压信息和速度信息，当处理完毕后再处理低优先级队列中的空调温度信息、油耗信息和FM频率信息。在处理中优先级队列中的数据的过程中，当接收到倒车信息并添加到高优先级队列中时，则优先处理该倒车信息。在处理低优先级队列中的数据的过程中，当接收到ACC信息并添加到高优先级队列中时，则优先处理该ACC信息；当接收到胎压信息并添加到中优先级队列中时，则优先处理该胎压信息。
本发明实施例的车载控制系统，通过对接收到的数据进行分组，添加到不同的优先级队列中，并按照优先级从高到低的顺序依次处理各优先级队列中的数据，从而使得重要数据能够被优先处理，提高了重要数据处理的实时性，避免了重要数据的阻塞，提高了车辆的安全性，提升了用户体验。
