摘　　要：为满足J-TEXT托卡马克装置电磁诊断的需求，研制了程控积分器系统。积分器系统采用模块化方式设计，由积分器板卡、控制器板卡、线性电源板卡和BNC接口板卡组成，并由上位机控制程序进行网络化控制。一套积分器系统可提供32路积分器通道，所有积分器通道均具有4种可供程控选择的积分时间常数，同时提供3种积分器运行控制方式。实验室和J-TEXT现场测试结果为：每路积分器通道的输出电压范围为-10～10V；输出噪声≤5mV；在4种积分时间常数条件下，积分器累计积分100s的输出漂移均小于5mV。In order to meet with the requirement of electromagnetic diagnosis to the J-TEXT Tokamak ,a remote control integrator system was developed .With modular design method , the integrator system is composed of the integrator cards , a control card ,a linear power card and the BNC interface cards ,and it uses the PC control soft-ware to conduct network control .An integrator system provides 32 integrator channels , and all integral channels have four kinds of integral time constants for remote selection and provide three kinds of integrator running control methods .According to laboratory and J-TEXT field testing ,it shows that the output voltage range is -10-10 V ,output noise is not more than 5 mV ,and for the four kinds of integral time constants ,the inte-gral output drifts are all less than 5 mV within 100 s for each integrator channel .
