可二次开发压力校准手操器的研究与实现

The Research and Realization of Developable Pressure Calibration Manual Operator

介绍了手持压力校准设备的开发模式,从界面设计、系统设置、实时时钟和逻辑处理几个方面详细阐述了可二次开发压力校准手操器的研发过程。应用嵌入式实时操作系统μCOS-Ⅱ和EMWIN开发界面和应用程序与传统的开发模式比较,更快捷和方便,手持设备调用对话框的回调函数以实现触摸屏和机械按键触发动作的同时响应,并对窗体进行重绘。经测试比较,可二次开发的压力校准手操器可以稳定高效地实现压力仪表的计量校准和信息采集,达到了预期的设计效果。

It introduces the development mode of the handheld pressure calibration equipment, and elaborates the development process of the pressure calibration manual from the aspects of interface design, system setting, real-time clock and logic processing. The application of embedded real-time operating system, cosine-Ⅱ and EMWIN to develop the interface and application program is faster and more convenient than the traditional development mode. Through the test comparison, the pressure calibration manual operator which can be developed twice can realize the metering calibration and information collection of the pressure meter stably and efficiently, achieving the expected design effect.
