Problems solved by technology

However, the way of artificially adjusting the opening of the flow valve is too dependent on human subjective experience, and the enterprise needs to assign a special person to be responsible for this work, which increases the labor cost of the enterprise
In addition, the method of artificially adjusting the valve opening is not accurate enough, and it is not suitable for flow valve usage scenarios that require high-precision opening adjustment

Abstract

The invention discloses a flow valve opening adjustment method and system based on parameter updating and correction. The method calculates the first parameter value of the constructed flow valve opening calculation model, and incorporates artificial adjustment of the flow valve in the parameter updating and correction. In addition, the second parameter value is updated and corrected based on the calculated trend of the opening adjustment error changing with the flow value, which reduces the influence of fluid temperature and other factors on the calculation of the model parameter value, and improves the calculation of the opening adjustment parameter value. precision. In addition, after the flow valve is put into a new application scenario, it only needs to be manually adjusted once to adjust the corresponding opening of the flow valve that meets different flow requirements to solve the first parameter value of the model opening adjustment parameter. The acquisition, calculation and update of the second parameter value and the correction process are completely automatic, which solves the trouble of sending a special person to the site to adjust the opening of the flow valve every time when the flow rate is to be changed, and the problem of relying too much on manual adjustment experience.

Description

Flow valve opening adjustment method and system based on parameter update and correction technical field The present invention relates to flow valve opening degree control technical field, be specifically related to a kind of flow valve based on parameter update correction Opening adjustment method and system. Background technique [0002] The flow regulating valve (referred to as the flow valve) is an intuitive and simple flow regulating control device. Opening to control the size of the flow. The demand flow is related to factors such as water level and is usually not fixed, and the demand flow changes when the demand flow changes. At present, the commonly used practice is to send someone to the site to manually adjust the opening of the flow valve according to work experience to meet the traffic demand. However, the way of artificially adjusting the opening of the flow valve is too dependent on the subjective experience of people, and the enterprise needs to assig...
