Control method and control system for spray curing system for cement concrete elements

Abstract

The invention discloses a control method and control system for a spray curing system for cement concrete elements. The control method comprises the following steps of the step 1, acquiring spray curing data of the cement concrete elements to form a data set S, wherein the spray curing data includes temperature and humidity of the surface of each cement concrete element, and the temperature, the humidity and the wind speed of an environment where the elements are located; the step 2, establishing weak classifiers according to the data set S, and performing classification on the data set S; performing integrated optimization training and assessment on the multiple weak classifiers by employing a 10-fold cross validation method to obtain a strong classifier; and the step 3, dynamically judging the on and off states of a spray switch according to sensor real-time parameters in the step 1 by the strong classifier obtained in the step 2, and executing an error correction mechanism based ona timed control method. The control system for the spray curing system for the cement concrete elements can decide the state of the spray switch according to parameters including the real-time temperature and humidity of the surface of each element, the temperature and humidity and the wind speed of the environment, and the like.

Description

technical field [0001] The invention belongs to the technical field of spraying and curing of cement concrete components, and in particular relates to a control method and a control system of a spraying and curing system of cement and concrete components. Background technique [0002] With the rapid development of my country's transportation facilities, cement concrete components are increasingly used in the field of highway bridges. During the curing process of components, the continuous hydration of cement concrete releases a large amount of heat of hydration. Due to the poor heat dissipation performance of cement concrete, there is a large temperature difference between the interior and exterior of the concrete. keep in good health. If leakage occurs during the component curing process, it is very easy to cause shrinkage cracks in the component, which seriously affects its strength and durability. Spray curing is adopted by most cement concrete components due to its goo...
