Embodiment 1

[0051] see figure 1 , a flowchart of a LabVIEW-based pipeline monitoring method provided by an embodiment of the present invention. A kind of pipeline monitoring method based on LabVIEW that the embodiment of the present invention provides, comprises:

[0052] Serial port initialization step S100: the serial port initialization unit performs data initialization settings on the resource name, baud rate, data bits, parity, stop bits and flow control corresponding to the VISA serial port. Among them, the resource name can be customized according to user needs. The setting of baud rate and data bit refers to the output serial port parameters of the data acquisition device of the lower computer. The default parity is none, and the stop bit can be customized according to user needs. Set, the default flow control is none, the serial port initialization is the basis for the normal data communication using the VISA serial port, through the initialization of the VISA serial port, the r...

Abstract

The invention provides a pipeline monitoring method and system based on LabVIEW, and relates to the technical field of pipeline operation and management. The pipeline monitoring method and the system based on LabVIEW comprises the following steps that firstly, data initialization setting for a resource name, a baud rate, a data bit, parity checking, a stop bit and flow controlling corresponding to a VISA serial port is conducted by a serial port initialization unit; secondly, a first temperature data, a second temperature data, a flow data and a pressure data collected by a lower computer are read by a data reading unit through the VISA serial port; thirdly, the data is optimized through a data processing unit, and corresponding numerical information and curve information are generated, when the numerical information exceeds a preset security range, an alarm is started; and finally, the numerical information and the curve information are displayed by a data display unit. According to the technical schemes, the technical problems of complicated pipeline monitoring mode and low monitoring efficiency existed in the prior art are alleviated, the existing pipeline data monitoring method is simplified, visual and striking embodiment of the pipeline data are realized, and efficiency of pipeline data monitoring is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline operation management, in particular to a pipeline monitoring method and system based on LabVIEW. Background technique [0002] At present, the premise of the normal operation of the pipeline is that the pipeline monitoring results are qualified and there is no leakage in the pipeline. During the actual transportation of pipelines, pipeline leakage often occurs due to external or internal factors. The cause of pipeline failure is mostly the loss of pipelines caused by natural disasters. In addition, as the service time of pipelines increases, the surface of pipelines will be corroded or damaged by various media, which will eventually cause property losses and cause environmental pollution. Regardless of the cause of the pipeline failure, it will lead to different degrees of danger. Therefore, if these problems are not discovered in time in actual transportation, the consequences will be unimagina...
