Design of PTZ control system based on STM32 two-axis deep water observation

Abstract： With the deepening of research on underwater robots in the field of marine energy exploration, they need to use the PTZ to monitor the underwater environment in real time to ensure safe and efficient operations. Therefore, a two-degree-of-freedom deep-water observation PTZ and its control system based on the STM32 main control board are designed. FreeRTOS to divide the application into multiple tasks with different priorities and allocate CPU system resources reasonably. RS485 is used to realize the communication between the PTZ and the upper computer. The upper computer sends control commands to the lower computer of the PTZ according to the Modbus two-way communication protocol. While realizing the rotation of the two-axis pan/tilt motor, the upper computer receives the detected data in real time. The PID algorithm is used to control the rotation angle of the PTZ. By analyzing the experimental results, the system can achieve two-degree-of-freedom control of the PTZ and the collection of high-quality pictures and videos.
