3、ent have realized the function 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

4、 can control several small modules. 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 emerge

5、ncy-ring line by using the infrared transmission. 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. IntroductionIn

6、 medical, it requests the speed of a bit of 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 requirem

7、ent. This design uses the infrared check installation 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 en

8、actments in advance. To increase systematic practicality, 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 h

9、ospital by the liquid speed supervisory and control arrangement 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 d

10、esignA. SCM brief introduction: SCM is more called as tiny 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

11、it came forth,it was convenient in industrial control, data collection 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. T

12、herefore application and the development of SCM have become high-tech 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 dis

13、placement of straight line, make digital signals into pulse signals, give 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 simpl

14、e , has steady performance. Consideration uses a pair of pipe,lean droplet to fall 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 alti

15、tude first, and detection drips now. Then, regulate repeatedly, controlling step into the 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 dete

16、ction Technology, realize its warning function. Let infrared transmitting tube with take over 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 stro

17、ng 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 designSoftware design is systematic crucial link. If hardw

18、are is skeleton, software is “muscle and nerve. Software design is mainly with signals and control signal s outputting, the communication between main station and stations and showing with keyboards controlling program. (1) Keyboard with showing is complete modular and the frequency that shows are t

19、he things that we will consider, because of having measured the speed of a bit, the frequency that shows can set according to needs completely. (2) The software about the communication between main station and stations: With relapse test and elaborate design, with the isolation technology of chief l

20、ine us have realized standing for war all functions, can realize efficiently to stand for the control of station. Major stands to dispatch information are contained from station number and sign position, as well as the control data that it wants. Stations are in always to take over state , will want

21、 to return to main station information, state changes over to dispatch, datas dispatching completely is still in to take over state, wait main station control and inquiry. Main station adopts to decide point with tour inspection two ways. (3) Software flow chart is as Fig 3:IV. Experiment Result (1)

22、 A bit speed control: Set a speed of a bit, the measure by every time with showing that. At the same time, regulate the high to control the speed of a bit, shows as follows: In table, the data analysis of test can be known ,this system has reached title requirement completely ,also, has highest prec

23、ision under the condition in the mezzo speed, in the two ends of dropping rapid of controlling scope, the controlling error is also on the small side.(2) Liquid surface inspection to give an alarm test: Measure liquid surfaces altitude give an alarm,under the case of the fast rapid speed, have recor

24、dedsome groups of data, is 2.5 respectively.(3) For system enter the time needed by steady state test, the longest time is 1 minute and 32 seconds, this time is from the lowest end to the highest end, and the regulation time of other condition is smaller than this number. By the time that this syste

25、m enters steady state, is smaller than the index. It satisfies title requirement.V. ConclusionThe system have completed title requirement basically and have realized the control regulation of a bit, can compare accurate regulation to assume random setting value .In systematic design course, it is si

26、mple that we make great effort line in line with practical attitude, to make the hardware circuitry simpleness and bring into play the agile of program and let high limit to excavate SCM resource, in order to satisfy problem requirement to keep close to life reality. However, since time is hurriedly

27、 and the ability infinity. This system still has the place of many worthwhile improvements, with the expecting of the readers criticism and comment.REFERENCES1 Zhang Hong-run Zhang Ya-fan.
