Problems solved by technology

However, there is a common problem with the existing methods, that is, these methods are all "off-line" adjustment methods, which can only be used during the debugging or maintenance of the ventilation system, causing great inconvenience
In addition, both the progressive flow method and the fan base pressure method require adjustment from the state where all dampers are fully open / closed, which may lead to extreme air volume values ​​and bring ventilation safety hazards

Embodiment Construction

[0051] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0052] The first embodiment of the present invention provides an online wind balance control method of an offshore platform ventilation system, which is used for balance control of a multi-cabin ventilation system on an offshore platform.

[0053] First, the structure of the ventilation system is introduced. The ventilation system includes a main fan, which is connected to each cabin of the platform through pipelines. Each cabin is equipped with an air outlet, damper and damper controller, wherein the opening of the damper determines the air volume of the air outle...

Abstract

The invention provides an online wind balance control method and system for an ocean platform ventilation system. According to the method, the target air outlet volume of each cabin air outlet is set, the real-time air outlet volume of each cabin air outlet is collected, and the ratio rx of the actual air outlet volume of each air outlet to the target air outlet volume is calculated; the ratios are adjusted to be consistent r *; and adjusting the rotating speed of the total fan according to r * so as to balance the air volume of each air outlet. According to the requirement for multi-air-outlet control of the ocean platform ventilation system, multi-agent consistency cooperative control is applied to the air balance problem of the ocean platform ventilation system. Special ventilation system maintenance or debugging time is not needed, online adjustment can be achieved, when the ventilation system operates normally, the air balancing device is used for air balancing, and the influence on a ventilation system user is reduced in practical application.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to an online wind balance control method and control system of an offshore platform ventilation system. Background technique [0002] The ventilation system is an important basic project of the offshore platform, which is used to balance the cooling and heating loads of the cabin, improve the indoor air quality, control the indoor cabin pressure, and the concentration of toxic gases. Therefore, the operation of the ventilation system is related to the normal life of personnel and the normal work of platform equipment. [0003] Offshore platform ventilation systems are unique. There are many types of cabins on the platform, and the individual requirements for cabin ventilation are high. Specifically, each cabin has different ventilation requirements. For example, cabins such as kitchens and central engine rooms have significantly different ventilation requirements when t...
