Embodiment 1

[0063] The embodiment of the present invention provides a cargo oil loading and unloading control method, which is especially suitable for 65,000-ton crude oil tanker, see figure 1 , the method includes:

[0064] Step 101: The industrial computer receives the corresponding relationship between the rotation speed of the cargo oil pump and the flow rate of the cargo oil, and establishes an expert system database.

[0065] In practical applications, it is possible to first obtain the various rotational speeds of the cargo oil pump and the flow rate of the cargo oil corresponding to the maximum working efficiency when the cargo oil pump rotates at various rotational speeds, and then according to the various rotational speeds of the cargo oil pump and the cargo oil pump at various rotational speeds The flow of cargo oil corresponding to the maximum working efficiency when rotating, artificially draws the corresponding curve between the rotation speed of the cargo oil pump and the f...

Embodiment 2

[0121] An embodiment of the present invention provides a cargo oil loading and unloading control system, see Figure 5 , the system consists of:

[0122] Target receiving module 201, configured to receive the target flow of cargo oil;

[0123] A determining module 202, configured to obtain the target rotational speed of the cargo oil pump from the target flow rate according to the corresponding relationship between the rotational speed of the cargo oil pump and the flow rate of the cargo oil;

[0124] The adjustment module 203 is used to adjust the speed of the cargo oil pump and the opening of the flow regulating valve according to the actual speed of the cargo oil pump, the actual pressure at the inlet of the cargo oil pump, the actual pressure at the outlet of the cargo oil pump, and the actual opening of the flow regulating valve, so that The actual speed is equal to the target speed, and the actual flow of cargo oil is equal to the target flow.

[0125] In practical app...

Abstract

The invention discloses a control method and system for loading and unloading of cargo oil, and belongs to the field of ships. The method includes the steps of receiving target flow of the cargo oil; obtaining a target rotating speed of a cargo oil pump according to the target flow and the correspondence relation between the rotating speed of the cargo oil pump and the flow of the cargo oil; and adjusting the rotating speed of the cargo oil pump and the opening of a flow regulating valve according to the actual rotating speed of the cargo oil pump, actual pressure of a cargo oil pump inlet, actual pressure of a cargo oil pump outlet and the actual opening of the flow regulating valve so as to enable the actual rotating speed and the target rotating speed to be equal and the actual flow of the cargo oil to be equal to the target flow. By means of the method and system, automation of loading and unloading of the cargo oil is achieved, the workload of workers is greatly reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to the field of ships, in particular to a cargo oil loading and unloading control method and system. Background technique [0002] The cargo oil handling and ballast system is an important part of an oil tanker, generally including cargo oil pumps and stripping pumps for pumping cargo oil, ballast pumps for filling or draining water ballast tanks, and control Oil pump, stripping pump and ballast pump realize the control system of cargo oil loading and unloading. [0003] The existing control system is basically manually operated by the staff: after the oil tanker arrives at the unloading port, the cargo oil pump is started to unload at the rated rate through the control system; The speed of the cargo oil pump; when the remaining cargo oil in the cargo oil tank reaches the second set value, the cargo oil pump is turned off through the control system, and the stripping pump is started to strip the tank to extract the remaining oil....
