Research on Control Method of Weight Compensation at the End of Concrete Pouring Pass

In order to improve the weight accuracy of the concrete pouring of the precast components, the control method for weight compensation at the end of the concrete pouring pass is researched and designed. First, starting from the production process of concrete pouring of precast components, the reasons for the weight deviation of the concrete pouring at the end of the pass are analyzed. Then, the control idea of weight compensation at the end of the pass is designed. Based on the kinematics theory and control theory, the geometric weight model for component and pouring weight model at the end of the pouring pass are established. Using the equal relationship between the above two models, the control solution of weight compensation at the end of the pass is obtained by mathematical derivation. At last, the execution steps are given. The actual production data of concrete pouring is used to carry out experimental verification. The results show that the control method for weight compensation at the end of the pass can significantly reduce the deviation of the concrete weight at the end of the pass. It can not only improve the accuracy of the pouring weight of precast concrete components, but also reduce the manual intervention and increase productivity.
