智能USB-CAN数据适配器设计与应用

Design and application of intellective USB-CAN data adapter

针对TDT2000低压综合保护器系统中存在的数据处理复杂、通用性不强、建站不灵活等缺点,开发设计了USB-CAN数据适配器,该适配器在硬件设计时采用外扩RAM的技术,软件设计引入MODBUS协议作为共同遵守的第三方协议,大大增强了系统对数据的智能处理能力,从而使这项研究具有广阔的应用前景．

There is some shortage in the TDT2000 tow-voltage integrat ed protector system, such as handling data complicated, using discommodious. Designing USB-CAN data adapter, which adopts technique of extending RAM in the hardware＇s design, inducts MODBUS protocot in the software＇s design as the third protocol. It enhances handling data, so it will have wide application.
