The invention discloses an intelligent identification method for abnormal hidden dangers of oil pipeline inspections based on drones. It combines the precise cruise technology of drones with target detection algorithms to design an intelligent inspection method for oil pipelines. On the basis of computer processing and computing capabilities, a relatively fast patrol inspection of hidden dangers in oil pipelines has been realized. The present invention has made a large number of optimization algorithms and improvements for the target detection of the special working conditions of the UAV patrol inspection, trained the special target detection network model under this condition, and has the quasi-real-time hidden danger broadcast for the oil pipeline patrol inspection, which reduces the manual patrol inspection The blindness greatly improves the inspection efficiency, reduces labor costs, and is practicable.

The invention discloses a surface polishing device for machining a new energy automobile motor. The surface polishing device comprises a bottom box and a machine body, the bottom box is arranged at the bottom of the machine body, side plates are arranged on the left side and the right side of the machine body, the back of the machine body is provided with a lining plate, the two side plates are provided, the side edges of the same square position of the two side plates are both connected the left side and the right side of the lining plate are fixedly connected in a welding mode. According tothe surface polishing device, a silencing device is arranged, the generated noise can be adsorbed to a certain extent during polishing, noise pollution caused by noise transmission is avoided, so thatthe equipment is more environment-friendly, a supporting plate is arranged, so that a workpiece can be placed on the sliding plate and the square plate for proper rest, or the arm of the worker is placed on the sliding plate and the square plate for polishing operation, so that the arm can be prevented from being held for a long time to carry out polishing so as to produce aching pain, the working efficiency is higher, and the polishing wheel can be moved forwards and backwards according to needs, the operation is more convenient.

The invention relates to an equivalent alternative power supply circuit for a thermal battery and a power supply method for an equivalent alternative thermal battery, which belongs to the technical field of alternative power supplies in the experimental stage, and solves the problem that the existing thermal battery alternative power supply cannot output current and circuits that meet the needs of the controlled circuit The structure is complex and requires the cooperation of software and hardware. The power supply circuit includes a first delay circuit and a second delay circuit; according to the current size required in the working process of the controlled circuit, the DC power supply is selected to be delayed by the first delay circuit or the second delay circuit. control circuit power supply; the first delay circuit includes the first magnetic latching relay and the first delay relay, the sum of the delay time of the two is equal to the delay time of the thermal battery; the second delay circuit includes the second magnetic latching relay, the second delay time Two delay relays and high-power electromagnetic relays, the sum of the delay times of the three is equal to the delay time of the thermal battery. The output circuit has a simple structure, can be realized only by hardware circuit, has low cost and strong stability.

The present invention discloses a method and a device for optimizing Automatic Cell Planning (ACP) using Drive Test (DT) data. The method includes the following steps: reading DT data and simulation data; computing DT path loss and simulation path loss of a grid point based on the DT data and simulation data; when the current grid point has no DT path loss, computing influence path loss of the current grid point with influence function algorithm based on the simulation path loss of the current grid point and the DT path loss and simulation path loss of the grid point around the current grid point; computing correction path loss of the current grid point based on the influence path loss and simulation path loss of the current grid point and a preset weight; performing ACP optimization with iterative algorithm based on the correction path loss. With the present invention, the DT data is processed using influence function algorithm, which takes into consideration the influence to the path loss caused by the object attributes in electronic map and makes full use of the DT data to correct the simulation data, thus improving the accuracy and usability of the ACP optimization.
