基于LabVIEW的煤质化验数据传输系统

LabVIEW-Based Coal Quality Test Data Transmission System

结合物联网技术,设计了一种基于LabVIEW的煤质化验数据传输系统。该系统由硬件和软件组成,硬件采用两级数据处理方式降低了资源占率,仪器串口传来的化验数据通过系统第一级打包处理后发送到第二级进行数据处理,再打包成为云端数据库需要的数据格式,通过网络接口发送到云端数据库。软件的主要功能是查看和保存数据,对下位机进行初始化配置。通过在实验室环境中进行测试实验,结果表明系统可以实时准确的上传数据,该系统对于解决传统火力发电行业煤质化验仪器数据上传时效性差和准确性低的问题有一定帮助,具有良好的应用前景。

Combined with IoT technology, a LabVIEW-based coal quality test data transmission system is designed. This system consists of hardware and software. The hardware adopts a two-level data processing method to reduce the resource occupancy. The test data from the serial port of the instrument is packaged at the first level of the system and sent to the second level for data processing, and then packaged into a cloud database. The main function of the software is to view and save data, and to initialize the lower machine. Through the test experiments in the laboratory environment, the results show that the system can upload data accurately in real time. The system is helpful to solve the problems of poor timeliness and low accuracy of data uploading for traditional coal quality testing instruments in thermal power generation industry, and has good application prospects.
