| Electrical parameter includes voltage,current,power,frequency,power factor ,and so on .The adjustment system of electrical network needs many panel instruments that can show the electrical parameter,such as voltage,current,power,cycle etc.TJsually these instrument is not accurate,wastes manpower resource,and the management of the data is inconvenient and easy to mistake.Recently the development of micro-electronics technology and the advent of SLSI.especially the advent of singlechip,lead to a new revolution in the field of instrument.In this paper , on the basis of studying the up to date fruit of instrument ,a new intellective instrument which adopts singlechip as control core and which can communicate with the PC is designed. This appliance which bases on the singlechip compounds the technology of computer and measure. It is improved very much on processing result and the diversification of function. |
