The application discloses a space network networking method and device, a network resource arrangement platform and a storage medium. The method comprises the following steps: in the case that a UAV service accesses a network, the position of the UAV performing the UAV service is determined; the service score corresponding to the cell within the preset distance range from the position of the UAV is determined; the preset number of cells with the highest service score are determined as the space candidate working cells, and the number of adjustable beams of the space candidate working cells is determined; and the space-to-air beam and the ground-to-air beam of the space candidate working cells are determined and set according to the number of adjustable beams. The application solves the technical problems that the UAV space coverage scheme in the related art mostly needs to add equipment for transmission transformation, the cost is too high, the scheme of covering the space by directly using the existing site resources has too great influence on the ground coverage, and the beam resources for covering the space are wasted.

This invention relates to the field of five-axis machining technology and discloses a method for measuring the Z-axis value of the workpiece coordinate system origin and the tool length. The method involves placing the Z-axis setter on the upper surface of the workpiece; with the spindle stopped, lifting the handwheel pulse generator and gently pressing the spindle end face against the elastic upper plane of the Z-axis setter; adjusting the movement ratio of the handwheel pulse generator to "X1"; moving the spindle away from the Z-axis setter; mounting the tool on the spindle; adjusting the movement ratio of the handwheel pulse generator to "X1" again, and the pointer of the Z-axis setter pointing to the "0" mark; due to the addition of the Z-axis setter, the Z-axis value h0 of point B in the workpiece coordinate system in the machine tool coordinate system A is -h - h1 - 50, where 50 is the fixed height of the Z-axis setter. This method ultimately yields the Z-axis value of the workpiece coordinate system origin. This method reduces the cost for companies to purchase on-machine measuring instruments and tool pre-setting devices, achieving high operation speed, high efficiency, high precision, and excellent cost-effectiveness.

The application belongs to the technical field of digital twin tool machining, and particularly relates to a diamond tool machining method, system and equipment, the method comprising: establishing a space coordinate system in a real space and a three-dimensional coordinate system in a corresponding digital twin, modeling a metal body and determining the actual central angle position of each slot, and modeling a diamond tool bit; obtaining basic welding parameters, simulating the welding process of the metal body and the diamond tool bit through the digital twin; obtaining the position error of each diamond tool bit after simulation welding compared with a design drawing; according to the position error, performing attribution analysis, and adjusting the welding sequence and the preset posture according to the analysis result; until the error meets a preset convergence condition, the welding sequence and the preset posture are converted into instructions and sent to a production line to perform diamond tool machining. The application reduces the welding error of the diamond tool, and avoids the occurrence of tool bit splashing and damage.

The invention provides an air conditioner electric heating control fault recognition system and an air conditioner thereof, and belongs to the technical field of air conditioners. The system fault detection unit is connected with the microprocessor and is used for detecting the working state of the electric heater after the microprocessor sends out a disconnection instruction and judging whether the relay has a contact adhesion fault according to the working state of the electric heater; wherein the fault detection unit can be a voltage detection module, and voltages at the two ends of the electric heater are safely collected through a differential amplification circuit for direct judgment; or an inner disc temperature sensor can be reused, and indirect judgment is carried out through abnormal temperature rise of the evaporator; a power detection module can also be used for analyzing the power change of the whole machine; on the basis of maintaining a low-cost framework of a single relay, real-time and accurate identification of electric heating control faults is realized, a user is prompted through sound-light alarm, potential safety hazards caused by relay faults are effectively avoided, and the method has the advantages of being low in cost, high in reliability and easy to implement.

The invention relates to an air cooling heat dissipation structure of an elevator energy recovery device. The air cooling heat dissipation structure comprises airflow holes, a shell, deflection baffles and a cabinet door. The shell is composed of a cuboid-shaped shell body and a top cover plate, and the top cover plate is welded to the top of the cuboid-shaped shell body. Cabinet doors are hinged to two sides of the shell; airflow holes are formed in the top bottom of the shell and the cabinet doors; the deflection baffles are arranged on the inner wall of the shell and arranged on the same vertical plane in a vertically-spaced and crossed mode. The system has the beneficial effects that airflow generated when the elevator runs in the hoistway is adopted as a cooling medium of the energy storage battery, the heat exchange effect is high, temperature distribution is uniform, and cost is zero; heat generated in charging and discharging of the energy storage battery is quickly brought out of the equipment by airflow, so that the problem of heat accumulation of the equipment is effectively solved with zero cost, the energy-saving device is more energy-saving, and meanwhile, the structure is simple in process; the deflection baffles are arranged on the inner wall of the shell and are arranged on the same vertical plane in a vertically-spaced and crossed mode, the flowing time and distance of airflow in the shell are prolonged, and heat exchange is more sufficient.
