摘　　要：描述了一套多路动态场空间分布实时测量系统 ,该系统是一套以微机为中心的数字化系统 ,可实现多路动态场空间分布的实时测量 .系统由微机、TMS32 0 C5 0板、开关电路、检波器、传感器、放大器等设备构成硬件系统 ,并通过编制 C5This paper describes a real time measuring system on dynamic field's space distribution, which is a digital system and uses a computer as its core. The system measures multiple channels dynamic field's space distribution in real time. The hardware in system consists of a computer, a digital processing card (TMS320C50), switch circuits, detectors, sensors and amplifiers. The software includes the embedded software of C50 card and the master control program of the computer.
