3、on of spot speed monitoring and control.To make the system more useful,we add figure-keyboard to it,with which people can set the function of spot speed by ones wish.Now,based on the communication among the SCM（s）,consists of a SCM-internet by which one major module can control several small modules

4、.Monitoring and controlling the function of spot speed is the major utilize of the small modules.Besides,emergency-ring,speed setting up and figure displaying and those shall realize the rest.This system monitors the function of spot speed and setting up emergency-ring line by using the infrared tra

5、nsmission.Its resisting interference is so strong that the monitor-precision shall rise greatly.The advantage rich resources of SCM are exploring completely which make function of the system stronger Key words:#SCM;#the Infrared Transmission.I.Introduction In medical,it requests the speed of a bit o

6、f transfusion to control in certain scope.Traditional transfusion installation in transfusion course,accompanying the liquid unceasing decreasing in transfusion bottle and the transfusions speed of a bit unceasing reduction,cannot satisfy medical requirement.This design uses the infrared check insta

7、llation testing speed of a bit,transformation it to digital signal and inputs SCM.SCM shows it using numberal pipe and at the same time SCM controls walking electrical machine according to design,to make the speed control of a bit in the scope that enactments in advance.To increase systematic practi

8、cality,from digital keyboard of SCM,user can communicate according to the network and enactment the drop speed of set point by ones need,can realize transfusion a bit of several wards from control system.It can replace transfusion with existing hospital by the liquid speed supervisory and control ar

9、rangement of a bit which have the characteristic with simple control and high precision.There is wide market prospect in the aspect of hospital and family tend,having higher society and economic benefits.It just follows as fig 1:#II.Hardware design A.SCM brief introduction:#SCM is more called as tin

10、y controller definitely,is 20 century middle of 70 decade development getting up a kind of rule modular of integrated circuit that faces control,its characteristic is function strong,volume little,reliability is high,price cheap.Once it came forth,it was convenient in industrial control,data collect

11、ion and intelligence melt the fields such as appearance,electromechanical unifinication and home appliances and have gotten extensive application,also have raised automation level and the technical level of these fields maximally.Therefore application and the development of SCM have become high-tech

12、 with asignificant program of project field.B.Walk into generator:#It is a kind of conductedelement of digital control system.It can change the digital quantitative change of input,is correspondingangular displacement or the displacement of straight line,make digital signals into pulse signals,give

13、firstly pulse signals,motor turns a angle or ongoingone step.Sketch is Fig.2:#THE speed inspection of a bit design:#It adopts the infrared sensor drop speed of measurement point,project with direct current,circuit is simple,has steady performance.Consideration uses a pair of pipe,lean droplet to fal

14、l take off reflection infrared ray will make accept pipe unknown and produce low level signals,but reflection signals is too weak,can not be monitored efficiently.The speed control:#It is fast to set an initial altitude first,and detection drips now.Then,regulate repeatedly,controlling step into the

15、 revolution of generator according to the relation between high and drop speed reaching suitable,make droplet satisfy to set drop speed highly.The high detection of face of blade with alarm:#Using infrared detection Technology,realize its warning function.Let infrared transmitting tube with take ove

16、r pipe just for set up in bottle two side,and set up in the altitude of cordon,because of sensor when having water with sink water receive signals strength difference.Therefore but basis take over the strong weak difference of signals,with comparator handling,can get the greater telecommunications discrepancy that water level arouses in critical line,and judging from whether water level reaches cordon,SCM sends alarm signals.III.Software design Software design is systematic crucial link.If hardware is skelet
