摘要
介绍了HART手持器的硬件、软件及功能特点。该手持器采用DSP作为处理器,较好地实现了实时信号处理的要求。设计按照HART协议规范可实现与任何遵循HART协议的设备间的通信。另外,通过自编程序更好地满足了用户的特殊要求。该设计为HART通信协议在智能仪表中应用做了一些有益尝试。
The paper introduced the hardware, software and functions of the handheld terminal. The handheld terminal uses DSP as a processor and implements realtime signal process perfectly. The design implements the communication between the handheld terminal and HART instruments and meets the user's requirements. It is a useful attempt of HART protocol in application of intelligent instruments.
