A control method and control system of a cement concrete component spray health maintenance system

Abstract

The invention discloses a control method and a control system of a cement concrete member spray health preservation system. The control method includes the following steps: Step 1. Acquire the spray health preservation data of the cement concrete member to form a data set S. The spray health preservation data includes cement The temperature and humidity of the surface of the concrete member, the temperature, humidity and wind speed of the environment where the member is located; step 2, based on the data set S, construct a weak classifier to classify the data set S; use 10-fold cross-validation method to classify multiple weak classifiers The integrated optimization training and evaluation are carried out to obtain a strong classifier; step 3, the strong classifier obtained in step 2 dynamically judges the on and off status of the sprinkler switch according to the real-time parameters of the sensor in step 1, and executes the method based on the timing control method error correction mechanism. The cement concrete member spray health care control system adopting the invention can determine the spray switch state by itself according to the real-time temperature and humidity of the member surface, ambient temperature and humidity, and wind speed and other parameters.

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...
