The Soft Design Of VxWorks-based Electro Energy Data Acquire Terminal

In this thesis the author describes the design and implementation of a VxWorks-based electro energy data acquire terminal.The goal of this terminal is to acquire data of power station and substation.The includes several sub modules:data acquire,data save,data transmit.The function of the module of the data acquire is to acquire data of meter by multi-function watt-hour meter communication protocol.The key of the design of the software is the tty driver.The function of the module of the data save is to save data of meter in flash disk. The key of the design of the software is the TrueFFS file systems.The function of the module of the data transmit is to transmit data of meter to the master station. The key of the design of the software is the network driver.
