Petrochemical engineering wharf handling process safety early-warning system based on LabVIEW

Abstract

A petrochemical engineering wharf handling process safety early-warning system based on a LabVIEW comprises a video monitoring unit, a real-time monitoring unit, a safety management unit and an early-warning unit, wherein the real-time monitoring unit is especially used for monitoring parametric variation generated in liquid handling operation and comprises corresponding testing systems. The real-time monitoring unit collects signals of the concentration, temperature, pressure, flow and the like of liquid to be monitored and obtains related parameter values A, quantized values B of indexes in the safety management unit are manually input, and the parameter values A and the quantized values B are transmitted into a petrochemical engineering wharf handling process extension theory early-warning model developed based on a LabVIEW platform; when all the parameters meet settings, the early-warning model is triggered, the current state of the handling process is provided, and an early warning is given under abnormal or nonstandard conditions to inform related personnel to take pre-control measures. According to the system, the functions of on-line monitoring early warning, data query and visual display of the parameters of liquid in an oil pipeline can be achieved in the handling process.

Description

technical field [0001] The invention belongs to the technical field of petrochemical dock loading and unloading and safety early warning, and relates to an extension theoretical early warning model based on LabVIEW virtual instrument, in particular to a petrochemical dock loading and unloading process safety early warning system. Background technique [0002] The loading and unloading process of petrochemical docks is a production process realized by the continuous operation of oil tankers, various loading and unloading processes and mechanical equipment, several oil pipelines and labor force between the dock line of several kilometers and the oil depot area. [0003] The existing pipeline leakage detection technologies and methods at home and abroad are relatively mature, which can determine whether a pipeline leaks, the location of the leak, and issue an early warning. However, the convenience and intelligence of the monitoring software still needs to be improved. Profes...
