Emergency help signal panoramic projection device, method and terminal
ActiveCN121768121Bimprove intelligibilityIncrease the chance of being rescuedPicture reproducers using projection devicesElectric transmission signalling systemsPanoramaRadiology
The application belongs to the technical field of emergency help equipment, and provides an emergency help signal panoramic projection device, method and terminal, the device can continuously detect the spatial posture and rotating motion state of itself through the environment positioning module, generate corresponding posture data and direction data, the control module can obtain the data and determine the real-time projection pointing angle of the device, and then when the device rotates, the projection control instruction corresponding to the real-time projection pointing angle is generated and sent to the image projection module, so that the image generation unit in the image projection module drives the corresponding rotating transformation of the help image, and the light source in the image projection module irradiates the help image to project the visual help signal which is right and complete. The scheme realizes omnidirectional controllable intelligent projection, can make the help signal cover all directions, at the same time ensures that the projected image can be clearly observed, is more easily identified by the rescuer, reduces the delay caused by signal blur, and improves the probability of being rescued by the help seeker.

Adjustable air turbine flow wave energy generation buoy and control method thereof
The application discloses a wave energy generating buoy capable of adjusting air turbine flow and a control method thereof. The buoy comprises an air turbine, a cam rotary disc, a driving gear, a driven gear, a servo motor, a driven shaft and a rigid buoy. An air chamber and a cavity are arranged in the rigid buoy, and an air pressure sensor and a liquid level sensor are arranged in the air chamber. The cam rotary disc is rotatably arranged between an air outlet and the air turbine, and is driven to rotate by the servo motor and a gear pair, so that the effective flow area of the air outlet is steplessly adjusted. The control method is based on the real-time collected air chamber pressure and liquid level change rate, calculates the optimal air chamber pressure corresponding to the optimal efficiency of the turbine, establishes the mapping relationship between the flow area and the pressure, and corrects the cam rotation angle in real time through PID closed loop control, so that the air chamber pressure dynamically tracks the optimal value. The application can optimize the wave energy capturing efficiency and the power generation power, widen the wave working condition adaptation range, and effectively prevent the turbine from being damaged by high-pressure air flow impact.
