生产者/消费者模式在剪切机检测系统中的应用

Application of producer/consumer mode to shearing machine detection system

现有剪切机检测系统主要采用主/从设计模式,其检测的参数多、数据量大、检测过程复杂,要求同时采集视频信号和物理信号,存在数据丢失和视频失真现象以及数据采集速度逐渐变慢等问题。为此提出LabVIEW生产者/消费者设计模式的改进方案,将物理信号和视频信号分开采集,分别采用两个循环来完成数据采集和数据分析,利用队列的方式来连接两个循环,实现各个循环的有效组合。经试验验证,改进设计大幅度提高了数据采集和分析速率,降低了各个信号之间的耦合性,对避免数据丢失和失真现象有很明显的效果,值得在机械、电气、能源等行业的各种试验检测系统中运用推广。

The existing shearing machine detection system mostly adopts the master/slave design mode,which involves many parameters to be detected,a large amount of data,and a complicated detection process,and it requires simultaneous acquisition of video signals and physical signals.Moreover,the system has data loss and video distortion,and the data collection speed becomes slower over time.To solve the above problems,a LabVIEW producer/consumer design mode improvement scheme was proposed.The physical signal and the video signal were separately collected,and the data acquisition and data analysis were respectively performed in two cycles,and the two loops were connected by means of a queue to realize an effective combination of each cycle.It has been verified by experiments that the improved design greatly improves the data acquisition and analysis speed,reduces the coupling between the signals,and is obviously effective in avoiding data loss and distortion.So it is worthy of application and promotion in various inspection systems of the mechanical,electrical,energy and other industries.
