Oil tank cleaning robot monitoring system based on valve controller

Abstract

The invention discloses an oil tank cleaning robot monitoring system based on a valve controller. The monitoring system includes a robot control unit, a system control unit, a sensing communication unit and a monitoring alarm unit, wherein the robot control unit, the system control unit, the sensing communication unit and the monitoring alarm unit are connected with a valve controller; the robot control unit includes an automatic cleaning mode and a manual cleaning mode, robot walking control, and extending and shrinking control; the system control unit comprises shooting lighting, and start / stop control of a cleaning pump, a hydraulic pump, an inflator pump, a vacuum pump and a filter press pump, and cable coiling and laying control for an umbilical cord coiling and laying device; the sensing communication unit includes a camera, an encoder, a combustible gas concentration detection sensor, an oxygen concentration detection sensor, a liquid level sensor, a pressure sensor and a motorized valve; and the monitoring alarm unit includes an integrated industrial control computer, a monitor and an alarm. Compared with the prior art, the oil tank cleaning robot monitoring system based on a valve controller has the advantages of being convenient to control, being high in intelligent level, being high in reliability of the system, and realizing safety, high efficiency, energy saving and environmental protection for the cleaning work of an oil tank cleaning robot.

Description

technical field [0001] The invention relates to the field of automatic cleaning control of oil storage tanks, in particular to a monitoring system for an oil storage tank cleaning robot based on a valve controller. Background technique [0002] Utilizing storage tanks for storage is the main way of strategic petroleum reserves. During the long-term storage and transportation of refined oil storage tanks, a small amount of sand, soil, heavy metal salts and other impurities in the refined oil will settle and accumulate at the bottom of the storage tank together with water due to the density difference, forming a black and thick gel Substance, that is, oil storage tank bottom sludge. Impurities and moisture will reduce the quality of refined oil and affect the accuracy of oil product calculation; accelerate the corrosion of oil storage tanks, and in severe cases will cause perforation of the bottom plate, resulting in oil leakage accidents; generate and accumulate static elect...

AI Technical Summary

Problems solved by technology

Impurities and moisture will reduce the quality of refined oil and affect the accuracy of oil product calculation; accelerate the corrosion of oil storage tanks, and in severe cases will cause perforation of the bottom plate, resulting in oil leakage accidents; generate and accumulate static electricity, resulting in static electricity accidents

In addition, when the oil product is upgraded or replaced with different oil products, the remaining oil in the tank and the newly loaded oil cannot be mixed, and when the oil storage tank leaks or is damaged, it needs to be inspected or hot repaired. Oil storage tanks are cleaned, and oil storage tanks must also be cleaned and repaired regularly according to national regulations
