The Research And Exploitation To Transducer Based On Networked Virtual Instrument

With the development of the integrated device electronics, the technology of computer, information analysis and dispose, the technology of software, modernistic measurement engineering puts forward higher and higher request to the acquirement, amalgamation and disposition of information. The technology of virtual instrument is coming, which is the combo of the technology of measurement and instrument. It is based on computer automation. The handling ability and agility of the system of measurement are improved greatly because of the opening system of computer replacing single machine test. The Labview software invented by national instrument of US is adopted. It is the exclusive graphic software and has a lot of excellences, the program of flow, ample functions, the numerical analysis, disposition of information, drive of equipment which are praised by most consumers.Ethernet is often used and TCP/IP is a protocol which is used widely, TCP/IP is embedded in ROM belonged to field intelligent instrument in order to transmit and receive signal with TCP/IP. Then data acquisition, information distribution and system integration are assemblaged in Intranet, Ethernet Intranet and Internet are connected to make Internet to impenetrate the course of measurement and control.The actuation of the transducer is one of the important means to achieve industrial automation. This has a widely application and can enhance automation level, mechanical properties, production efficiency, and product quality and save energy. General transducer is widely used on every kind of transmission devices as a steady and highly precision speed control system. The speed control system of AC frequency conversion has virtue of energy conservation, wide regulating range, high accuracy, production efficiency, high power factor, high reliability, easy operation and easy interface with other equipment and so on. Transducer replacing DC driver system is an inevitable direction.A cheap monitored system is going to be done by LabVIEW which is made by NI Company. It is made of the technology of Ethernet and TCP/IP and some Occasional Technology is used, then a certain circuit is designed to acquisition date smoothly. Some theory is become into practice through the system, the function of the equipment is fully used, and the function of the virtual instrument is played in maximum. There are some roles of the system. First, it can detect Performance of the transducer to ensure its quality; Second, it can monitor the operation of the transducer to ensure its stability; Third, it can improve the quality of the worker; last it can raise the level of automation of factories. So it is a meaningful thing to expand the used scope of transducer and improve the level of automation.
