基于HART通信的涡街流量计的智能软件设计

在给出涡街信号的检测和流量计算的软件流程后，提出了实现流量计智能化的方法：将涡街流量计的各种功能参数化，即通过友好界面，用户可凭借设置特定参数项的值，达到智能仪表的软件组态、参数设定、自校正和自诊断、显示方式的选择、提供非测量用管理参数等功能。软件设计时，根据特定的参数项名称，给出相应的人机交互模块，很好地体现了软件设计的模块化思想。

Intelligent software design of vortex flow-meter with HART communication

After showing the program flow-chart about the vortices detection and flow calculation, a new way to realize intelligent functions is proposed, namely to realize functions by parameterization, that's to say, with friendly interface, the users can easily make intelligent instrument configuration program and perform parameters setting, self-correction, self-diagnosis, display mode selection, and management parameter determination by setting the value of a special parameter. In software design, a special man-machine interactive software module achieve according to the name of parameter item is offered, to the modularization of the software.
