4results about How to "Extend inspection time" patented technology

The invention relates to the technical field of unmanned aerial vehicles, in particular to a limited space cable unmanned aerial vehicle inspection system based on a GPS signal-free condition, which comprises an unmanned aerial vehicle navigation module, a cable detection module, an obstacle avoidance module, an environment monitoring module, a data processing and recording module and a power management module, autonomous navigation of the unmanned aerial vehicle in a limited space is realized, the cable detection module monitors the surface state of a cable based on a convolutional neural network model, the obstacle avoidance module dynamically detects obstacles and adjusts a flight path, and the environment monitoring module monitors temperature, humidity and air quality and gives an early warning when the temperature, humidity and air quality exceed a safety threshold. The data processing module processes data in real time in combination with an edge computing technology and uploads the data to a control center, and the power management module regulates and controls energy consumption through an intelligent algorithm and automatically returns or emergently lands when the electric quantity is insufficient; the method is suitable for a cable inspection task in a GPS-signal-free environment.

The invention discloses a multi-degree-of-freedom underwater robot, and relates to the technical field of submarine cable inspection, the multi-degree-of-freedom underwater robot comprises a main body, a fixing frame is fixedly arranged in the main body, and two sides of the bottom of the main body are rotatably connected with clamping guide plates. After the robot body dives to the position of a submarine cable, under the action of two sets of bidirectional air cylinders, the two sets of clamping guide plates clamp the outer side of the cable to a certain degree, and when the robot body advances in the seabed, under the clamping action of the two sets of clamping guide plates on the outer side of the cable, the cable is clamped by the two sets of clamping guide plates; a worker only needs to enable the main body to advance through a remote controller, so that the main body can carry out advancing inspection operation along the trend of the cable, and the angle of the main body does not need to be adjusted in real time, thereby avoiding the situation that the worker needs to adjust the advancing direction of the main body in real time due to improper operation, so that the overall cable inspection time is prolonged; and the overall working efficiency is effectively improved.

The invention provides a mobile parking platform applied to an indoor inspection unmanned aerial vehicle and a control method. The mobile parking platform comprises a platform body; the energy storage unit is located on the platform body and used for storing electric energy; the charging unit is located on the platform body and used for charging the unmanned aerial vehicle; the walking unit is located on the platform body and used for driving the platform body to walk; and the controller is in communication connection with the energy storage unit, the charging unit and the walking unit, the controller is used for controlling the walking unit to work under the condition that the unmanned aerial vehicle needs to be charged, so that the mobile parking platform walks to the position of the unmanned aerial vehicle, and the controller is further used for controlling the energy storage unit to discharge and controlling the charging unit to work, so that the unmanned aerial vehicle is charged. According to the scheme, the problem of short endurance time of the inspection unmanned aerial vehicle in the prior art is solved.

The utility model belongs to the technical field of medical treatment and public health, and particularly relates to a device capable of stabilizing intestinal tracts in vitro in colonoscopy, which comprises a bellyband main body. The bellyband body is wound on the belly through bonding of the first male hook-and-loop fastener and the first female hook-and-loop fastener, the steam injection expansion portion is reserved, and the pressing ball is bonded to the steam injection expansion portion through the second female hook-and-loop fastener and the second male hook-and-loop fastener. After the position of the pressing ball is adjusted, the inflatable latex ball is pressed to inject steam, a balloon switch on the inflatable latex ball is closed after fixation, and the balloon switch is deflated and taken down after examination is finished, the examination time is obviously shorter than that of a traditional method for fixing the intestinal canal by pressing the abdomen in vitro through a nurse, and the method has obvious advantages in improving various efficiencies, reduces the examination risk, reduces the pain of a patient and improves the examination efficiency. The patient satisfaction degree is improved, the endoscope entering difficulty of doctors is reduced, the examination time is shortened, the day examination number of patients is increased, the patient turnover rate is increased, hospital income is increased, and the workload of nurses is relieved.
