6 Marks Mapping
| Mark | Required component | Where it appears in the diagram |
|---|---|---|
| 1 | Sensors | Left block: Sensors collect crash / impact / vehicle state data. |
| 2 | Release airbag | Bottom block: MCU sends actuator control to Release Airbag. |
| 3 | MCU | Centre block: MCU performs local control and decision logic. |
| 4 | Communication link | Right arrow: NB-IoT / Satellite with MQTT / HTTPS links MCU to cloud. |
| 5 | Analytics in cloud | Right block: Cloud Analytics stores data and supports dashboard / diagnosis. |
| 6 | Connection with vehicle MCU | Top block: MCU is connected to Vehicle MCU through CAN. |
Diagram Standard Check
审查结论：这张图是合理且符合评分标准的。
- 结构和老师官方图一致：Sensors 在左，MCU 在中间，Vehicle MCU 在上方，Release Airbag 在下方，Cloud Analytics 在右侧。
- 6 个评分点都被单独画成可见元素或清晰标签：Sensors、Release Airbag、MCU、communication link、Cloud Analytics、Vehicle MCU connection。
- 箭头方向合理：Sensors 把数据送入 MCU；MCU 触发 Release Airbag；MCU 通过 CAN 连接 Vehicle MCU；MCU 通过 NB-IoT / Satellite / MQTT / HTTPS 把数据送到 Cloud Analytics。
- 通信链路写法标准：NB-IoT / Satellite 表示底层连接方式，MQTT / HTTPS 表示应用层或传输协议，符合 IoT architecture block diagram 的常见写法。
- 考试作图时可以画得更简单，但必须保留这 5 个方框和 4 条关键连接线，否则容易漏分。
Short Written Explanation
The sensors collect crash, impact or vehicle state data and send it to the MCU. The MCU is connected to the vehicle MCU through CAN and can trigger the airbag actuator when required. The MCU also sends data to the cloud through a communication link such as NB-IoT, satellite, MQTT or HTTPS. The cloud performs analytics, stores historical data and supports reporting, dashboard display and later diagnosis.
