Problems solved by technology

[0005]The ventilation control method currently applied to offshore platforms is mainly through the monitoring of the air flow, temperature, pressure and other parameters in the cabin by the air conditioning system to realize the flow and pressure of the air conditioning system. Poor automatic control, but this method relies on hardware measures such as fans, differential pressure transmitters, PLC controllers, etc., and also requires manual operations by operators, which brings inconvenience to the ventilation of offshore platforms
In addition, there is a method to select the corresponding ventilation mode and fan type according to the type of each cabin of the offshore platform and the specific requirements, and this method needs to consider the specific conditions of the cabin, and carry out specific thermodynamic modeling for the cabin. More cumbersome and not universal

Abstract

The invention provides an ocean platform ventilation system control method based on temperature and hydrogen sulfide concentration control, and the method comprises the following steps: building a hydrogen sulfide gas concentration change differential equation in an ocean platform cabin, defining a variable air volume air box and an air handling unit in each cabin as an intelligent agent, and obtaining N + 1 intelligent agents, wherein N is the number of the ocean platform cabins; fitting the intelligent agents by adopting a neural network, wherein each intelligent agent comprises an actor network responsible for generating a strategy and a critic network responsible for evaluating the strategy in real time; defining states and actions of N + 1 agents at the moment t, and defining temperature and hydrogen sulfide concentration overrun penalty functions of the agents in the cabin; and performing intelligent agent training. According to the control method of the ocean platform ventilation system, the hydrogen sulfide gas with the temperature and the concentration exceeding the standard in the ocean platform cabin can be controlled.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a control method for an ocean platform ventilation system based on temperature and hydrogen sulfide concentration control. Background technique [0002] The ventilation system is an important public system to ensure the normal production and personnel life of the offshore platform. In order to ensure the normal production of the platform and the normal life of the staff, both the living area and the production area of ​​the offshore platform should be ventilated to effectively eliminate the heat dissipation of the electronic equipment room To maintain the design temperature of the room, to ensure the normal operation of electrical equipment; different areas, ventilation methods and ventilation volume will be different, and whether there is good ventilation is an important basis for the division of dangerous areas on offshore platforms, and it is also related to platfor...
