据《人民长江》报导,沙市水位站利用微机代替人工观测水位获得成功。微机水位数据采集装置系通过电缆将观测井内的水位数据讯号送到近100m外办公室内的计算机,计算机控制每隔1个小时自动打印一次水位。微机水位每秒钟左右采样一次,采样10～35分钟后,其平均值就是定时水位观测值,水位误差≤2cm的保证率为99.8%。每个月末用磁带机录制一次水位数据磁带,由其它计算机打印出水位月报表和绘 According to “The People’s Yangtze River”, Shashi Water Station succeeded in replacing the artificial observation water level with a microcomputer. Computer water level data acquisition device through the cable to the observation well within the water level data signal to the office near 100m outside the computer, the computer control every 1 hour automatically print a water level. Microcomputer water level sampling about once every second, sampling 10 to 35 minutes, the average is the timing of water level observations, water level error ≤ 2cm guarantee rate of 99.8%. At the end of each month with a tape recorder to record a water level data tapes, by other computer to print the water level monthly report and painted
