In this paper , a safe , reliable , and intellectual control plan is provided aiming at the heat charge for dwelling district , which contains epigynous machine responsible for data processing and hypogynous mahcine responsible for unlocking the valve , by means of serial communication between them , combining homemade three - channel valve , to adminstrate the charge data and the valve efficiently . the main idea is based on the homemade three - channel valve . the vavle is locked at peacetime , while it is opened with the help of open tool and a water flow in the caliduct . as soon as the flow stops , the valve locks automatically . the open tool has data in its memory , and implement function by lcd and keyborad . so it can identify data and drive motor , to open the valve intellectually . the epigynous machine database manage system administrator the dweller information , standard heat charge and payment infomation etc , including store , configure , query , print etc , then store in the memory of open tool . as a result , the plan can do well in the experiment 此阀平时是锁闭的,只有用开启器配以暖气片中的水流才可打开,一旦水流断开,则此阀会自会锁闭。而开启器则是根据其存储器中的数据配以液晶显示及小键盘,完成数据确认及电机驱动,自动对相应用户的三通阀打开特定角度,完成开启任务。上位机数据库管理系统完成对用户信息、热费标准、缴费信息等原始数据的常规管理,包括存储、设置、查询、打印等,最后将处理后的数据传到开启器中存储。
