电磁线圈驱动中CAN通信及其实现技术

Realization of CAN Bus Communication in Electromagnetic Coil Drive

电磁线圈驱动通常需要几十、甚至几百个电源模块,因此高功率脉冲电源模块的实时触发及充放电过程中的参数控制与测量成为电磁线圈驱动过程中极为重要的组成部分。此系统选用CAN(控制器区域网)作为现场控制总线,通过光纤传输控制和数据信号能满足多个电源模块的需要,以及避免驱动过程中的强电磁干扰。

In order to gain high muzzle velocity and drive heavier object, electromagnetic coil driving needs several even hundreds of electrical source modules. Therefore the timely touch off of the high-pulsed power electrical source modules and the controlling and measuring of the charge and discharge parameters have become the critical components for Electromagnetic coil driving. The system brings forward CAN as the field control bus, uses fiber as the communication medium, thus, it fulfills the need of the electrical source modules and avoids the strong electromagnetic disturb in the process of driving.
