Abstract: With a single-chip microcopy (SCM) as its core and assists with some electrical wires, using the infrared technology and so on, this instrument 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 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 emergency-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. Introduction

In 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 transfusion’s speed of a bit unceasing reduction, cannot satisfy medical requirement. 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 enactments 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 one’s 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 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 design

A. 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 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. Therefore application and the development of SCM have become high-tech with asignificant
