日本研制出一种利用计算机管理居民用水的自动化系统。这种系统是通过公用电话线,将自来水公司水表读数中心的个人计算机同装有电子仪器的居民水表集中读数装置连接在一起的,能够自动地进行水表读数並抄送水费账单资料。这种自动化系统还具有监测自来水是否有泄漏情况的功能。用该系统抄表,从居民水表集中读数装 Japan has developed an automated system that uses computers to manage residents’ water use. This system connects the personal computer of the water meter reading center of the water company with the meter reading device of the residential water meter equipped with electronic instruments through a public telephone line, and can automatically read the water meter and copy the water bill data. This automated system also has the ability to monitor tap water for leaks. Use this system to read the meter and collect readings from the residents’ water meters
