一种数据传输方法、车载通讯设备及计算机可读存储介质
交叉引用
本发明要求在2018年10月22日提交至中国专利局、申请号为201811229327.0、发明名称为“一种数据传输方法、车载通讯设备及计算机可读存储介质”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明涉及物联网领域，尤其涉及一种数据传输方法、车载通讯设备及计算机可读存储介质。
背景技术
随着5G时代的到来，物联网成为了后续科技产业的重要发展方向，作为物联网应用中前沿产品，车载(Tbox，Telematics box)产品正在和空调、天窗等设备一样，成为汽车的标配功能。车载Tbox产品的通讯功能，可以让车主享受如听歌、上网、交流等数据业务；同时，如远程控制、远程诊断、空中下载技术(OTA，over-the-Air Technology)升级等车载物联网专有业务，可以让车主随时随地的和他的汽车相连，从而了解汽车安全状态、控制汽车功能，使得车主和车辆之间可以“随时沟通”。其中，当车辆在点火状态时，由发动机为车载Tbox供电；当车辆在熄火状态时，由电瓶蓄电池为车载Tbox供电，为了解决车辆熄火后蓄电池电瓶馈电的隐患，需要对电源进行管理。
具体的，车载Tbox的电源管理状态包括为Working状态、Standby状态、Sleep状态和Off状态，其中，当车辆点火时，车载Tbox处于Working状态，在Working状态下，可以进行包括数据和语音等所有业务，此时，耗电量较大，当车辆熄火后，车载Tbox切换至Standby状态、Sleep状态或者Off状态，在Sleep状态下，数据业务断开，可以通过短信进行业务，功耗较Working状态而言比较低，在Sleep状态和Off状态下，车载Tbox 关闭射频，处于关机状态，在这两个状态下，不进行任何业务，功耗较低。Sleep状态和Off状态的区别时Sleep状态会定期唤醒至working状态，从而和网络获取联系，定期唤醒的Polling时间一般设置成两个小时或者三个小时，当车辆一直不点火时，为了防止蓄电池电瓶馈电，最终将车载Tbox切换至Off状态。
然而，当车载Tbox处于Stanby状态时，需要服务器走短信流程才能触发业务，具体的，服务器端需获取车载Tbox的电源管理状态后，通过MQTT Fallback SMS机制完成数据业务从MQTT到SMS协议的状态，对车载Tbox和服务器都建立基于PS/CS两套协议来完成物联网业务，导致车载Tbox物联网业务代码构建内部流程复杂；当处于Sleep状态和Off状态时，车载Tbox相当于处于关机状态，导致无法及时进行物联网业务；当前车载Tbox网络管理涉及到不同电源管理状态的切换，不同电源管理状态的切换定义不同的唤醒条件，这些唤醒条件需要软硬件结合实现，导致当前车载Tbox网络管理过程复杂。

本发明实施例中，服务器的类型包括物联网业务类服务器和应用类服务器，具体的根据实际情况进行选择，本发明实施例不做具体的限定。
可选的，与车辆控制管理服务相关的服务器为物联网业务类服务器，如车辆管理控制软件等。
可选的，与在线应用相关的服务器为应用类服务器，如听歌软件、即时聊天软件等。
本发明实施例中，用户在手机端下载不同的APP，并与车辆Tbox进行连接，此时，用户通过在手机APP界面上进行相应的操作，此时，手机APP通过对应的服务器向车载Tbox发送第一传输请求。
S402、车载通讯设备将第一传输请求确定为数据传输请求。
当车载通讯设备接收到服务器发送的第一传输请求之后，车载通讯设备就要将第一传输请求确定为数据传输请求。
S403、车载通讯设备获取当前启动状态。
当车载通讯设备将第一传输请求确定为数据传输请求之后，车载通讯设备就要获取当前启动状态了。
本发明实施例中，当前启动状态包括车辆点火和车辆熄火，当当前启动状态为车辆点火时，表征当前供电电源为电瓶蓄电池；当当前启动状态为车辆熄火时，表征当前供电电源为发动机。
S404、当当前启动状态为车辆点火时，车载通讯设备按照预设网络确定策略和数据传输请求对应的业务类型，确定当前传输网络，当前传输网络包括低速传输网络。
当车载通讯设备获取当前启动状态之后，车载通讯设备就要确定出当前启动状态为车辆点火时，按照预设网络确定策略和数据传输请求对应的业务类型，确定当前传输网络了。
本发明实施例中，车载Tbox配置了两种网络，分别为3G/4G网络和 NB-IOT网络，其中3G/4G网络由于传输带宽大使得耗电量也大，而NB-IOT由于传输的是小数据量，使得传输带宽小，耗电量也小。
本发明实施例中，当车载Tbox确定出当前启动状态为车辆点火时，车Tbox从数据传输请求中确定出业务类型，并根据业务类型和预设网络确定策略和业务类型，确定当前传输网络。
本发明实施例中，当前传输网络为3G/4G网络和NB-IOT网络中的至少一种网络。
具体的，当业务类型为远程控制类业务时，确定当前传输网络为低速传输网络和高速传输网络中的任一种；当业务类型为应用类业务时，确定当前传输网络为高速传输网络。
本发明实施例中，车辆处于点火状态时，发动机的供电电源容量非常大，此时，车载Tbox可以用高速传输网络传输应用类业务，用低速传输网络和高速传输网络中的任一种网络传输远程控制类业务，具体的根据实际情况选择执行，本发明实施例不做具体的限定。
S405、车载通讯设备采用当前传输网络，与服务器进行数据传输过程。
当车载通讯设备确定当前传输网络之后，车载通讯设备就要采用当前传输网络，与服务器进行数据传输过程了。
本发明实施例中，当业务类型为远程控制类业务时，车载Tbox采用NB-IOT输网络和3G/4G网络中的任一种，将第一远程控制业务数据发送至物联网业务类服务器，第一远程控制业务数据为对车辆控制器发送的第一远程控制信号进行处理得到的业务数据；或者，从物联网业务类服务器接收第二远程控制业务数据，以将第二远程控制业务数据进行处理并通过CAN网络传输至车辆ECU中。
本发明实施例中，当业务类型为应用类业务时，车载Tbox采用3G/4G网络，接收应用服务器发送的第一应用业务数据；或者，将第二应用业务数据发送至应用服务器，其中，第二应用业务数据为用户在车载Tbox的操作进行操作，从而生成的业务数据。
可以理解的是，车载通讯设备在车辆熄火时，切换至低速传输网络与服务器进行数据传输过程，由于低速传输网络耗电低，车载通讯设备无需 设置不同的电源管理状态，并为这些电源管理状态的切换定义不同唤醒条件，进而简化了实现流程和当前车载Tbox的网络管理过程。
