Abstract
The main research content of this system is to realize the linkage control of multi-axis motor through LabVIEW and single chip microcomputer. The operator can operate the upper computer software to send the speed and spatial coordinate instructions remotely. The expansion chip ch438q is used to store temporarily, and then the data is transmitted to the processor of max13487 for control. According to the RS485 serial port communication mode, the analyzed data parameter information is transmitted In the stc15 single-chip microcomputer on four single axis control cards, the motor is controlled by the driver to make the controlled object move to the specified position quickly and accurately. In the process of movement, the upper computer can display x, y in real time. In order to test and use the system to achieve certain functions, a set of high-precision multi angle video acquisition system based on three-axis linkage and four axis control is designed. The selected camera is a 120°wide-angle camera, which can make the range of scenery observed from a certain point of view much larger than that of human eyes in the same view point Monitoring. After many experiments, the accuracy of the system can reach 1μM. The system itself can also expand a variety of functions according to different needs, which has a certain practical value.
