目前数据获得系统中广泛使用的磁带器件,平均输入数据时间在秒的数量级上,预计十年后这种器件将被半导体存贮器件取代,输入时间将缩短1/4~1/10倍。目前,微型计算机数据获得系统的设备硬件和软件的研制和维修造价比例相等,各占总价的三分之一,今后十年预计设备硬件造价比例将下降25%,软件研制与维修造价比例将增加,达75%。
The current widespread use of data acquisition systems tape devices, the average input data on the order of seconds, it is expected that 10 years later, the device will be replaced by semiconductor memory devices, input time will be shortened 1/4 to 1/10 times. Currently, the microcomputer data acquisition system hardware and software development and maintenance costs equal to one-third of the total price, the next 10 years is expected to reduce the proportion of equipment hardware costs will be 25%, software development and maintenance costs will be the proportion of Increase, up to 75%.
