诊断中性束时序控制系统的研制
Design of timing control system for diagnostic neutral beam device
-
摘要: 在研究了诊断中性束(DNB)对控制时序要求的基础之上，针对传统控制系统带来的低可靠性和低集成度等不足，研制了一套DNB时序控制系统：包括主要由PC机和PIC单片机组成的硬件结构，以及在上下位机上开发的软件程序。实验表明该控制系统稳定可靠，为DNB装置投入HT-7实验奠定了良好的基础。Abstract: The DNB (diagnostic neutral beam) device is a physical diagnostic system. The timing control subsystem plays a critical role in running DNB device. In order to produce diagnostic neutral beam accordantly with desire, timing control must provide a series of pulses accurately and orderly. The control requestments of the DNB system are studied. Based on this, the timing control unit is designed, including structure of PC in combination with PIC single chip microcomputer and software application. The experiment shows that the timing control unit is steady and reliable.
