Embodiment Construction

[0014] The present invention provides a data acquisition method used in a real-time monitoring system, the method includes using the application software of the real-time monitoring system to collect multi-channel data, wherein the application software of the real-time monitoring system will be used to The program for collecting channel data is divided into different sub-modules, each sub-module controls at least one channel to perform data acquisition functions; a thread is assigned to each sub-module; a different memory is assigned to each thread in the computer memory Space; execute multiple threads at the same time, and collect data from multiple channels at the same time, such as figure 2 shown.

[0015] The application software of the real-time monitoring system can be a variety of graphical programming engineering application software, for example, software such as LabVIEW or Lab Windows / CVI. Among them, the application software that should have the most real-time mon...

Abstract

The invention provides a data collection method in a real-time monitoring system, which comprises the following steps: multipath data is collected by the application software of the real-time monitoring system, wherein the application software of the real-time monitoring system is used for dividing program collecting the multipath data into different subsidiary modules, and each subsidiary module controls at least one channel for executing the function of data collection; a thread is designated for each subsidiary module; different memory space is respectively designated for each thread in the memory of a computer; multiple threads are executed simultaneously; and data is collected for multiple channels. All channels in a data channel of the same type in the application software of the real-time monitoring system can execute operation simultaneously by using the data collection method. The data collection method prevents the data collection of a software system from lagging behind the data collection of an external hardware data collection system, and consequently, the reliability of the real-time monitoring system is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a data collection method executed by a computer in a real-time monitoring system. Background technique [0002] When the existing real-time monitoring system needs to collect data from two or more devices at the same time and process the collected two or more channels of data in real time through the application software installed on the computer, often because Due to the limitation of application software functions, the collected two or more channels of data cannot be read into the computer at the same time, thus greatly reducing the real-time performance of the system. [0003] For example, in the gearbox fatigue test data acquisition system, it is necessary to collect data from two motors operating in different states at the same time, and input the collected data into the computer, so that the specific application software installed in the computer can be Based on these da...
