| Abstract: | The design of the online dynamic ore-weighing system for electrical shovels is presented. In the system, the slave computer collects the data and transmits them to the master computer through serial communication for computing. All variables that may influence the shovel weight are analyzed by dynamic knowledge and suitable sensors are selected for measuring them according to their characteristics and scope. The slave unit AT89C52 controls a periodic sampling and transmits the sampling values to the master PC, which does the computing, memory and display based on Visual C++ language. |
