国外水文仪器的发展趋势,是朝着智能化方向发展。在这总的发展趋势下,国外的水文仪器越来越普遍地采用计算机技术,尤其是采用微处理器和小型机控制,实现对各种水文信息的检测、分析、处理、传递、调节与控制等自动化过程,并开始或者推广采用激光、超声、光纤、固态存储、卫星通信等新技术,从而使水文仪器的可靠性和适用性均有很大的提高。美国的地质调查局计划在几年时间内将该局管辖内的所有的水文仪器改造成智能化的形 The development trend of foreign hydrological instruments is to move towards intelligence. Under this general trend of development, foreign hydrological instruments are more and more widely used computer technology, especially the microprocessor and minicomputer control, to achieve a variety of hydrological information detection, analysis, processing, transmission, regulation and control Etc., and started or promoted the use of new technologies such as laser, ultrasound, optical fiber, solid-state storage and satellite communications, thereby greatly improving the reliability and applicability of hydrological instruments. The U.S. Geological Survey plans to transform all hydrological instruments within its jurisdiction into intelligent forms within a few years
