For inspectionAISlump of system to concrete 、Accuracy and system stability of fine aggregate moisture content and other items，Recently，Southern Road Machinery Green Building Materials Intelligent Equipment Research Institute and Dehua Shunda Building Materials Co., Ltd.“Carbon Reduction and Quality Improvement for the Future”Human-machine competition for slump prediction and intelligent detection of moisture contentAISystem stability test。Nanfang Road MachineAIWhether the system is reliable？AIAnd artificial who is better?？Let's find out together.。

Three experienced experimenters sent by Shunda Building Materials to compete against Nanfang Road Machine Concrete Slump Online in the Slump Prediction Man-Machine CompetitionAIMonitoring system，Take the field slump test data as the standard value，The participants predict the slump through picture monitoring.，The obtained data is compared with the standard value.。There are 5 rounds in total.，The winner is the one with the highest cumulative score.。
