This invention provides a pesticide spraying flow control system based on multi-sensor information fusion, comprising a multi-sensor information acquisition unit, a central control unit, and an execution drive unit. The multi-sensor information acquisition unit is used to collect data in real time on the travel speed, terrain slope, pesticide viscosity, and pipeline flow rate during pesticide spraying operations. The central control unit is configured to: perform parallel advance prediction; generate feedforward control quantities based on the advance prediction results and a dynamic compensation model; the dynamic compensation model is configured to perform coupled compensation based on the terrain slope angle and its rate of change, and compensation based on the temperature-calibrated pesticide viscosity; adaptively tune control parameters online and generate feedback control quantities based on the deviation between the real-time pipeline flow rate and the target flow rate; and weightedly fuse the feedforward control quantities and feedback control quantities to generate a total control command. The execution drive unit is used to adjust the opening of the flow regulating valve according to the total control command to achieve closed-loop control of the spraying flow rate.

This invention relates to cement pole inspection and discloses a cement pole quality inspection device, including a tripod. A positioning mechanism for auxiliary positioning is installed on the front side of the tripod. Above the positioning mechanism is a detection mechanism for detecting defects in the cement pole. A cleaning mechanism for cleaning the inner wall of the cement pole is located at the front end of the positioning mechanism. The positioning mechanism includes three diagonal braces. Each diagonal brace has a support rod hinged to its end away from the sliding block. A wall-supporting wheel is rotatably connected to the end of the support rod away from the tripod. A central shaft is rotatably connected to the axis of the tripod. A shaft groove is provided at the rear end of the central shaft. This invention provides stable, centered support through adaptive tightening, extends the detection depth through threaded extension, and ensures precise control over long distances through shaft-connected transmission, thereby significantly improving the adaptability to cement poles of different specifications and the efficiency of inspection operations.
