A kind of network multi functional electric energy meter is introduced,which is composed of 80C196KC microprocessor,PSD913F2 flash memory and RTL8019AS net interface controller.

This paper introduces a new intelligent network interface chip PS2000 and its application.

We introduce the realization method of the mechanical -electronic products network in this paper, the solution that how to make the network interface chip connect Internet is expounded in detail.

Focussing on the key points in the development of the device driver for high speed data transmission adapter based on the PCI I/O accelerator AMCC S5933 performed in Windows 2000,this paper places most importance on the analysis and explanations of OS, I/O accelerator,device driver and application programs.

The technical retrofit scheme for the system is analyzed,including the control function of the system and relevant requirements,realization of the network control interface,application of the programmable logic controller(PLC),and selection of network equipment.

Analyses of network interface controller and the setup of breakage service;
