基于组态软件Intouch的空压机试验控制设计
摘要:随着自动化技术的不断发展,空压机在人们的生活中的应用也越来越广泛,同时对空压机的各项性能要求也越来越严格,这就要求我们对空压机进行各项性能参数测试。由于现场测试具有一定的危险性,所以我们使用远程的监控系统来进行。Intouch组态软件是出现的比较早的一种过程可视化的组态软件,具有丰富的工控界面、数据库处理、对象连接等数据管理控制功能。本文就是以Intouch组态软件为基础,在windows环境下建立对空压机进行性能测试的人机界面,对空压机在试验过程中的各项参数(压力、温度)进行监视,并进行记录以便分析和判断是否符合技术要求。试验的现场数据通过现场传感器送入SWP-S80型智能仪表处理,再通过RS-485/RS-232接口转换器与PC机相连接,通过用VB编写的仪表数据通信程序实现组态软件与外部仪表间的通信,完成了现场实时数据的采集。同时监控界面也能生动地反应现场的实际情况,从而更好实现测试的安全性和准确性。

The Design Of pressor Test Base On InTouch
Abstract: With the continuous development of automation technology, pressor in people's lives are increasingly being used in applications, while the performance requirements of pressor are increasingly stringent, which requires us to carry out the pressor key performance parameters. As the field test has some risk, so we used to conduct remote monitoring systems. Intouch configuration software is relatively early emergence of a process of visual configuration software, has a rich industrial control interfaces, database processing, object linking and other data management control functions. This is to Intouch configuration software as the foundation, established under the windows environment to conduct performance tests on the pressor machine interface, pressor in the testing process on the parameters (pressure, temperature) were monitored and recorded to analyze and pliance with technical requirements. Field test data through the on-site sensors into the SWP-S80 smart meter deal with, and through the RS-485/RS-232 interface converter is connected with the PC, by written instrument with the VB program to achieve munication with the external configuration munication between devices, pleted on-site real-time data acquisition. Interface can also control the scene vividly reflect the actual situation, in order to better achieve the safety and accuracy of the test.
