基于虚拟仪器的数据采集及远程监测系统设计

Design of Data Acquisition and Remote Monitoring System Based on Virtual Instrument

为实现测试数据的远程实时传输,以LabVIEW为开发平台,利用串行通信及DataSocket技术,设计了基于串口的数据采集及Internet的远程实时监测系统,完成了数据的采集处理,显示保存、远程实时传输.同时给出了温度采集实例,利用温度控制器与SIM900A GPRS模块,实现了温度数据采集、远程监测、现场温度报警显示及远程短信报警的功能.与传统报警系统相比,测试系统安全、稳定、可靠,达到了设计要求.

To achieve the remote real-time transmission of the test data, the serial data acquisition and the Internet remote real- time monitoring system is designed by using serial communication and the DataSocket technology based on the LabVIEW development platform, which has accomplished data collection, process- ing, display, and the remote real-time transmission. A practical example with temperature acquisition is also given. The system uses temperature controller and SIM900A GPRS module to achieve the temperature data acquisition, remote monitoring, field temperature alarm display and remote SMS alarm functions. Compared with the traditional alarm system, the test system is safe, stable, and reliable, and the designing requirements are satisfied.
