技术领域
本申请涉及轨道交通领域，尤其涉及一种高速磁悬浮列车通信方法、通信系统及相关装置。
背景技术
目前，轨道交通中的控制器可以通过以太网来进行连接，但高速磁悬浮列车中单车(每个车厢)中的控制器较多，如果控制器之间通过以太网来连接，每个控制器都需要一根以太网线连接至交换机，将占用高速磁悬浮列车大量的夹层空间。
轨道交通中的控制器还可以通过控制器局域网络(Controller Area Network，CAN)来进行连接，但高速磁悬浮列车中的控制器较多，CAN网的走线较长，需要大量中继器保证CAN网中信号的稳定性，也将占用高速磁悬浮列车大量的夹层空间。
因此，本领域目前需要一种能够节约夹层空间的高速磁悬浮列车通信方法。

具体实施方式
为了帮助更好地理解本申请实施例提供的方案，在介绍本申请实施例提供的方法之前，先介绍本申请实施例方案的应用的场景。
目前，轨道交通中的控制器可以通过以太网来进行连接，但高速磁悬浮列车中单车(每个车厢)中的控制器较多，如果控制器之间通过以太网来连接，每个控制器都需要一根以太网线连接至交换机，将占用高速磁悬浮列车大量的夹层空间。
轨道交通中的控制器还可以通过控制器局域网络(Controller Area Network，CAN)来进行连接，但高速磁悬浮列车中的控制器较多，CAN网的走线较长，需要大量中继器保证CAN网中信号的稳定性，也将占用高速磁悬浮列车大量的夹层空间。因此，本领域目前需要一种能够节约夹层空间的高速磁悬浮列车通信方法。
为了解决上述的技术问题，本申请实施例提供了一种高速磁悬浮列车通信方法，该方法应用于高速磁悬浮列车，列车包括第一车厢和第二车厢；第一车厢包括第一控制器、第二控制器和第一交换机，第二车厢包括第三控制器和第二交换机；第一控制器接收第二控制器通过控制器局域网络CAN发送的第一消息；第一控制器通过第一交换机和第二交换机之间的以太网向第三控制器发送第二消息，第二消息根据第一消息生成。
由此可知，本申请提供的高速磁悬浮列车通信方法，每一个车厢内的控制器采用CAN网进行通信，车厢与车厢之间将信号通过交换机连接以太网进行通信。如此，由于CAN网可以将单车内多个控制器同时连接在总线上进行通信，减少了列车内通信线的布置，且由于车厢与车厢之间通过以太网进行连接，CAN网仅用于连接车厢内的控制器，缩短了CAN网走线的长度，减少了中继器的使用个数，节约了高速磁悬浮列车的夹层空间。
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本申请实施例作进一步详细的说明。
参见图1，该图为本申请实施例提供的一种高速磁悬浮列车通信方法的流程图。
本申请实施例提供的高速磁悬浮列车通信方法应用于高速磁悬浮列车，列车包括第一车厢和第二车厢；第一车厢包括第一控制器、第二控制器和第一交换机，第二车厢包括第三控制器和第二交换机。如图1所示，本申请实施例提供的高速磁悬浮列车通信方法，包括：
S101：第一控制器接收第二控制器通过控制器局域网络CAN发送的第一消息。
S102：第一控制器通过第一交换机和第二交换机之间的以太网向第三控制器发送第二消息，第二消息根据第一消息生成。
需要说明的是，本申请实施例中的第一控制器和第二控制器均位于第一车厢。第一控制器和第二控制器可以通过第一车厢内的控制器局域网络进行通信。第二控制器位于第二车厢，第二车厢与第一车厢内的第一控制器或第二控制器进行通信时，需要通过第一车厢内的第一交换机和第二车厢内的第二交换机连接以太网进行通信。
由此可知，本申请实施例中的每一个车厢内的控制器采用单独的CAN网进行通信，车厢与车厢之间将信号通过交换机连接以太网进行通信。一方面，由于CAN网可以通过一条CAN总线连接单车内多个控制器，减少了列车内通信线的布置。另一方面，由于车厢与车 厢之间通过以太网进行连接，CAN网仅用于连接车厢内的控制器，缩短了CAN网走线的长度，减少了中继器的使用个数，节约了高速磁悬浮列车的夹层空间。
为了更好地理解本申请实施例提供的高速磁悬浮列车通信方法，下面结合控制器局域网对该方法进行介绍。
参见图2，该图为本申请实施例提供的一种第一车厢内的控制器局域网的示意图。

其中，第一控制器101和第二控制器102均与车辆诊断计算机1连接，车辆诊断计算机1连接第一交换机104；第三控制器201连接车辆诊断计算机2，车辆诊断计算机2连接第二交换机204；第一交换机104和第二交换机204通过以太网连接。
如图3所示，本申请实施例中的控制器局域网络CAN包括车辆诊断计算机SDR；第一控制器向第一交换机发送第二消息，包括：第一控制器通过车辆诊断计算机SDR向第一交换机发送第二消息。相应地，本申请实施例中的第二交换机向第三控制器发送第二消息，包括：第二交换机通过车辆诊断计算机SDR向第三控制器发送第二消息。
高速磁悬浮列中的设备除了上述的车下设备，包括各种控制器外，还包括了一些车上设备，例如车内空调和车内自动门等。作为一种可能的实施方式，第一车厢还包括第一车上设备和第二车上设备。第一车上设备通过第一交换机向第二车上设备发送第三消息。需要说明的是，由于以太网传输的信息量较大，传输信息的实时性较好，车上设备直接连接至交换机利用以太网进行通信可以提高车上设备的灵敏性，从而提高用户的使用体验。
综上所述，本申请提供的高速磁悬浮列车通信方法，每一个车厢内的控制器采用CAN 网进行通信，车厢与车厢之间将信号通过交换机连接以太网进行通信。如此，由于CAN网可以将单车内多个控制器同时连接在总线上进行通信，减少了列车内通信线的布置，且由于车厢与车厢之间通过以太网进行连接，CAN网仅用于连接车厢内的控制器，缩短了CAN网走线的长度，减少了中继器的使用个数，节约了高速磁悬浮列车的夹层空间。
根据上述实施例提供的高速磁悬浮列车通信方法，本申请实施例还提供了一种高速磁悬浮列车通信系统。
参见图4，该图为本申请实施例提供的另一种高速磁悬浮列车通信系统的示意图。
如图4所示，本申请实施例提供的高速磁悬浮列车通信系统包括第一控制器101、第二控制器102、第三控制器201、第一交换机104和第二交换机204。
列车包括第一车厢和第二车厢；第一控制器101、第二控制器102和第一交换机104位于第一车厢，第三控制器201和第二交换机204位于第二车厢；
第一控制器101，用于接收第二控制器102通过控制器局域网络CAN发送的第一消息，并通过第一交换机104和第二交换机204之间的以太网向第三控制器201发送第二消息，第二消息根据第一消息生成。
作为一种可能的实施方式，控制器局域网包括8路总线段，8路总线段分别连接第一车厢中的多个控制器，多个控制器包括第一控制器和第二控制器。作为一种可能的实施方式，控制器局域网络CAN包括车辆诊断计算机SDR；第一控制器具体用于：接收第二控制器通过车辆诊断计算机SDR发送的第一消息。例如，第一控制器101接受第二控制器通过车端诊断计算机1(103)发送的第一消息。
根据上述实施例提供的高速磁悬浮列车通信方法和高速磁悬浮列车通信系统，本申请实施例还提供了一种高速磁悬浮列车，该列车包括上述实施例的高速磁悬浮列车通信系统。
