The Monitoring System Of Oil Level Based On Lab VIEW

This project stems from a oil field's commission and the purpose is to achieve congener product's technical request on the basis of reducing cost. Making using of the integrate principle of mechanism, electronics, optics, liquid factors, have designed a suit of feasible control blue print. The theory of measurement of system is using the balance of assistant heavy and floater's flotage and it's gravity. When the oil level changes, the floater rises or drops, the coder turns with steel wire, we get electrical signal relative to oil level. Characters of system is adopting flexible junction, precision of measurement is high. Dealing with the signal which we got, making using of bus of 485 transmit disposed data to PC to achieve function of inspect. On the basic of the knowledge of electrical circuit, the computer principle and intelligent instrument designing theory, researcher completely designs hardware of control system of oil level, Meanwhile on the aspect of software,a set of control demanded. System reaches the design request on the basis of hardware and software.Program of PC is using Lab VIEW to realize. Lab VIEW is the model of graphic program. The feature of graphic program is building inspect system of arrangement clearly, powerful function and interface of human with PC well basing on hardware/software's resource flat ,Lab VIEW is used,in the measure field more and more.PC has done the control of oil level's limit, receiving data subprogram, checking the data for guarantee the system running and save the important data for people inquire some day. Properly enlarge the system , which can inspect oil level or other parameters(like temperature)with oilcan group, have biggish economy and society value.
