The invention discloses a safety production monitoring system for a concrete mixing plant, and relates to the technical field of monitoring. The monitor comprises a monitor shell, one end of the monitor shell is provided with a mounting groove, the interior of the mounting groove is fixedly connected with protective glass, the interior of the mounting groove is fixedly connected with an image acquisition camera, and the interior of the mounting groove is fixedly connected with an infrared monitoring camera. When the surface of the transparent protective film is stained with dust, the transparent protective film is driven to circularly move around the multiple positioning rollers, and the cleaning rollers are matched to drive the dust collection fluff to wipe and adsorb the dust stained on the outer side of the transparent protective film; then the cleaned transparent protective film is moved to the front of an image acquisition camera and an infrared monitoring camera, so that synchronous collection and analysis of image data and heat data in the mixing plant can be conveniently completed by using the image acquisition camera and the infrared monitoring camera; and the cleaning roller and the dust collection fluff are matched to realize automatic cleaning of dust on the surface of the transparent protective film.

The application discloses a camera module and electronic equipment, and belongs to the technical field of communication equipment. The camera module comprises a base frame, a photosensitive chip, a first substrate, a second substrate, a first guide column, a second guide column, a first driving mechanism and a second driving mechanism. The first guide column is arranged on the base frame. The first substrate is movably connected with the first guide column and moves along the extension direction of the first guide column. The second guide column is arranged on the first substrate. The second substrate is movably connected with the second guide column and moves along the extension direction of the second guide column. The photosensitive chip is arranged on the second substrate. The first driving mechanism is connected with the first substrate.

The invention discloses an active and passive vibration damping device based on a piezoelectric actuator and a control method thereof, and aims to solve the problems that resonance is easy to occur and the vibration damping performance is obviously influenced by working conditions in the existing passive vibration damping method of a multi-rotor unmanned aerial vehicle, and the active vibration damping method is high in actuator stroke and energy consumption requirements, sensitive to system model errors and parameter drift and low in vibration damping performance. Therefore, the problem that the airborne camera of the multi-rotor unmanned aerial vehicle still has imaging blurring is solved. An upper platform of the device is connected with an unmanned aerial vehicle, the upper platform, a load platform, a piezoelectric actuator, a lower platform and airborne imaging equipment are coaxial from top to bottom, a spring assembly is connected with the upper platform and the lower platform, and the load platform penetrates through the lower platform through a plurality of connecting rods to be connected with connecting pieces of the airborne imaging equipment. And the multiple groups of spring assemblies and the multiple connecting rods are distributed around the piezoelectric actuator. According to the method, the piezoelectric actuator outputs reverse correction force according to the absolute acceleration of the device and the absolute acceleration of the load platform, and vibration reduction is achieved in combination with the spring assembly. The invention belongs to the technical field of vibration reduction.
