Design and Implementation of PFN Measurement and Control System Based on CAN Bus

In order to realize integrated modular of the Pulse Forming Network (PFN ) and make the Electro Magnetic Launch (EML)system extend and maintain easily,a solution based on CAN bus for electromagnetic emission measurement and control system was proposed. Firstly,according to the specific requirements of electromagnetic launchers and the characteristics of CAN bus communication protocol,the application layer protocol of CAN bus and a software based on Visual C# as the system man-machine interface were developed,which implemented remote monitoring. And then,through special design on the CAN bus node firmware and electromagnetic compatibility design for extreme environment of high voltage, large current and strong magnetic field, the reliability and security of the bus control system was guaranteed. The experimental results show that this measurement and control system has advantages of network,modularization,intelligence,which provides a new way for modular integration design of electromagnetic launch system.
