摘要
在简述20000L混合钟罩式气体流量标准装置工作原理的基础上,重点介绍了该套装置中测量和控制系统的功能与实现方法,下位机硬件设计和上位机软件开发的整体思路,并简述了如何在单一装置中同时实现固定容积法、可变容积法和标准表法三种工作模式,极大地增强了钟罩式气体流量标准装置工作的灵活性和机动性。装置上位机采用VB.NET,下位机采用测量控制柜集成模块,详细描述了测量控制柜模块组态和控制流程以及上位机实现流程和功能。
This paper mainly introduces the functions and implementation of the measurement and control system in a gas flow standard device of the 20000 l mixed bell jar type as well as the device’s working principles. It presents the hardware design of the lower computer and the software development for the upper computer. It also describes the way of realizing three working modes, based on the static volumetric method, the dynamic volumetric method, and the standard meter method, simultaneously in a single device, which greatly enhances the flexibility and mobility of the device. The upper computer of the device adopts VB.NET. The lower computer adopts the integrated module of measurement control cabinet. The configuration and control flow of the measurement control cabinet module and the realization process and functions of the upper computer are described in detail.
