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 does n ' 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
