EAST托卡马克新型积分器系统控制器的研制

Development of the New Integrator System Controller on the EAST Tokamak

为了满足EAST托卡马克的实验需求,提升积分器系统的可维护性和可测试性,研制了新型积分器系统控制器。该控制器采用ARM微控制器和轻量级IP协议栈,实现了积分器系统的网络化控制。所提供的参数设置指令可远程设置和读取积分器板卡上放大器的放大倍数,而控制指令则提供了初始化、标准信号积分、脉冲积分、积分保持、标定和探针测试功能。经实验和EAST现场测试,该积分器系统控制器可满足EAST装置的实验要求。

In order to meet with the requirements of the experiments on EAST Tokamak, and improve the main- tainability and testability of the integrator system, a new integrator system controller is developed, The controller uses an ARM micro - controller and the lightweight IP protocol stack to realize the network control of the inte- grator system. The provided parameter setting instructions are able to remote set and fetch the amplifiers＇ gain parameters, and the provided control instructions provide functions including： initialization, standard signal inte- gration, pulse signal integration, integration hold, calibration and probe test, Compared with the original design, the new controller simplifies the design of hardware and software, and improves the system performance, usabili- ty, maintainability and testability, Through laboratory and EAST field test, the integrator system controller is sta- ble and available to meet with the requirements of EAST experiments.
