Device for BMS system and network topology structure thereof

The invention discloses a device for a BMS system and a network topology structure thereof. The network topology structure thereof comprises a display panel, a main board and at least one load, and the main board acts as an upper computer and is connected with the display panel, the load and the BMS system which serve as lower computers through buses. According to the invention, the network communication topological structure of the equipment for the BMS system is simplified, the hardware cost of the equipment is reduced, and the effect of reducing the sizes of corresponding parts can be achieved. 本发明公开了一种用于BMS系统的设备及其网络拓扑结构。其中用于BMS系统的设备的网络拓扑结构，所述设备包括显示板、主板及至少一个负载，所述主板作为上位机通过总线与分别作为下位机的显示板、负载以及BMS系统连接。本发明简化了用于BMS系统的设备的网络通讯拓扑结构，降低了设备的硬件成本，同时还可以达到减小对应部件尺寸的效果。
