摘　　要：介绍了用于计算中性束注入实验中束流功率沉积的水流热量计系统优化及优化后的测试结果。前期的水流热量计系统利用串口传输和分散式牛顿模块采集,采样率低、传输速度慢、抗干扰能力差、无法满足实验要求;优化后的系统基于虚拟仪器,采用TCP\IP协议传输和虚拟仪器技术,提高了系统的采样率和精度、优化了数据传输速度及抗干扰能力。优化后的系统经测试可以准确监测中性束注入器装置上各热承载部件冷却水的温升及流量,并分析得到中性束注入时束流在各热承载部件上的功率沉积。实验结果表明优化后的系统工作稳定,使用灵活,数据准确,满足实验要求。This article introduces the optimization of water flow calorimeter system which is used to calculate the beam power deposition in NBI experiment and its experimental results after optimization. Previous water flow calorimeter system uses serial transmission and decentralized acquisition module. Its low sample rate, slow transmission speed, bad anti -jamming ability cannot meet the experimental requirements. Using TCP／IP protoeol and virtual instrument technology, the optimized system based on virtual instrument increases the sampling rate and accuracy, and transmission speed and anti -jamming capability are also improved. The optimized system can accurately measure the cooling water temperature rise and flow rate to calculate the beam power deposition on the heat -load components by test. Experiment results show that optimized system is stable, flexible, and can fully meet the experimental requirements.
