Intellectual Control System Of Heating For Separate Door

Heating centralized is an important thing in the north.Whether this is implemented in a large scale has contributed to impove city modern level and ameliorate atmosphere environment.The traditional heating system are two-upright-pipe-parallel system,two-pipe system,single-pipe-stride system etc,Whose calculation for heat charge is either by man or by IC installed on the caliduct.Therefore,the problem arise that heat provided doesn't accord with heat charge payed,not secure,and resident have to suffer much.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.
