摘　　要：为了满足ＧＭＤＳＳ的要求，扫描接收机必须与ＤＳＣ和ＮＢＤＰ终端密切配合，扫描要迅速可靠。目前我国有关部门和企业正在研制开发这种扫描接收机，笔者通过对国外两种典型的扫描接收机（Ｒ８００１，ＮＲＤ－７２０）微机控制系统的比较分析，找出了它们的共同点及其差异，并通过实验作了一些理论探讨。In order to meet requirements of the GMDSS,thescanning of a scanning receiver should bc reliable and quick so that the scanning receiver can be combined with a digit selective calling equipment(DSC)and a narrow band direct printing equipment(NBDP)perfectly,So far, some institutes and enterprises of Our country are researching and developing scanning receivers of various types,This paper analyses computcr controlling system of the foreign receivers of types R8001 and NRD-720,explains the common and different asp-ects of the two types,and analyses the result of the author’s experi-ments on the R8001 rcceivcr and NRD-720 receiver,It is hopcd that this paper will be helpfuI to those who research scanning receivers。
