产品描述 Product Introduction

[图片：image.png] 

RoboMaster测速模块内置传感器，可实时测量枪管处所经过的弹丸速度及频率。其CAN接口（即航空线接头）根据裁判系统通信协议，将获取的弹丸的射速和射频数据实时发送给裁判系统主控模块。当测速模块检测到弹丸经过时，LED灯将会点亮进行提示，增加比赛的趣味性。

The RoboMaster Referee System Speed Monitor Module is equipped with sensors that monitor the speed and frequency at which projectiles are launched from the barrel. Its CAN interface (i.e. aviation connector) transmits the data about the speed and frequency of projectiles launched to the Main Control Module of the Referee System according to the communication protocol of the Referee System. When the Speed Monitor Module detects a projectile, the LED light will turn on.
