The present invention provides an air cleaner, in which a casing has an air inlet pipe making air inflow along a direction perpendicular to the axis of a cylindrical filter element, and an air outlet pipe making filtered air outflow along the axis, and the casing has a supporter clingingly supporting the end outer circumference of the filter element on closed valley portions side along the circumference direction continuously, and another supporter supporting the end inner circumference of the filter element on closed mountain portions side along the circumference direction continuously to close a hollow portion, and air to be filtered inflows to the filter element from a first inflow space on the top side of the mountain portions as well as from the end of a second inflow space side, and filtered air outflows from the end on an outflow space side as well as from the hollow portion.

The invention provides a flight control method. The method comprises the steps that a flight control instruction transmitted by a control side is received; when the flight control instruction transmitted by the control side is received, whether entering a preset no-flight area is performed is judged after the flight control instruction is performed; and when entering the preset no-flight area is performed after the flight control instruction is performed, the flight control instruction is not responded and the flight control instruction is discarded. The invention also provides an unmanned aerial vehicle and a computer readable storage medium. The unmanned aerial vehicle can be prevented from flying into the no-flight area so that unnecessary harassment to the outside caused by the unmanned aerial vehicle can be avoided.

The invention relates to a power cable high-voltage test safety protection system and belongs to the cable high-voltage test safety protection technical field. The objective of the invention is to solve safety protection problems in a cable high-voltage test. The power cable high-voltage test safety protection system includes a guarding device, a monitoring device and a wire supporting device; the guarding device includes upright columns and scanning mechanisms; the monitoring device includes a control box, a current measuring instrument, a voltage measuring instrument, a controller, a signal transmitter and a display device; and the wire supporting device includes a supporting column, a wire frame, wire clamping mechanisms and temperature sensor mechanisms; and a tripod is adopted as a base. According to the power cable high-voltage test safety protection system of the invention, the guarding device, the monitoring device and the wire supporting device are adopted, so that the cable high-voltage test can be well protected; test data can be monitored in real time, a worker can effectively master a test process, and can take measures effectively when abnormalities appear in the test; and security incidents caused by problems in cable supporting can be effectively prevented.

The invention belongs to the technical field of poultry breeding, and particularly relates to a chicken raising environment-friendly yield increasing method applicable to a novel chicken farm. A master control module is involved, the master control module is connected to a chicken manure treatment module, an illuminance adjusting module and a music play module separately, black soldier flies are bred through chicken manure, after black soldier flies are cleaned away, chicken can be raised, protein nutrients are supplied to chicken, a chicken manure liquid separating module performs solid-liquid separation on chicken manure, the solid state and the liquid state obtained after separation can be sold, the land can be fertilized, and pasture, soybeans, grains and the like can be planted, whichis beneficial to increasing the yield; continuous chicken feeding can be performed, and the advantages of being ecologically used, economical and environmentally friendly are achieved; a spraying module performs humidification inside a chicken house regularly through a spraying device, meanwhile, the indoor temperature is controlled, by adding a deodorant into the chicken house, the chicken manure odor inside the chicken house can be eliminated, in the egg laying period of laying hens, classical music is played regularly, when the classical music is played one hour and played for 7-8 weeks continuously, the egg laying rate of laying hens can be increased by 10%, the hatching rate is greatly increased, and culture benefits are increased intensively.

The disclosure relates to an unmanned aerial vehicle flight training control method and an unmanned aerial vehicle flight training control apparatus. The unmanned aerial vehicle flight training control method includes the steps of obtaining a geographical coordinate scope of an actual no-fly zone and a current starting point geographical coordinate of an unmanned aerial vehicle; comparing the current starting point geographical coordinate of the unmanned aerial vehicle with the geographical coordinate scope of the actual no-fly zone to judge whether the unmanned aerial vehicle is within a non-no-fly zone; if the unmanned aerial vehicle is within the non-no-fly zone, controlling the unmanned aerial vehicle to fly along a preset virtual flight course, wherein the preset virtual flight courseincludes preset virtual barriers; obtaining attitude information and the geographical coordinate of the unmanned aerial vehicle; detecting the distance between the unmanned aerial vehicle and the preset virtual barriers; and judging whether the flight position of the unmanned aerial vehicle needs to be adjusted on the basis of the distance, form information of the preset virtual barriers and theattitude information of the unmanned aerial vehicle.

The invention relates to information protection and user identification. The technical result consists in functionality enhancement including: information encryption and decryption; electronic document authentication using an electronic digital signature; protection of electronic documents against copying, exchange of copy-protected electronic documents; settlements by means of electronic payment facilities; protection of software and databases against unauthorized copying. The inventive personal cryptoprotective complex comprises a code-carrying medium in the form of a cassette for protection of cryptographic data and a terminal device for communications with peripheral devices such as a personal computer, a telephone and a card reader. The cassettes for personal cryptoprotective complexes are embodied such that they have a unified architecture, common software and an identical secret mother code. A protective sheath of the cassette has light-reflective surfaces. A program for monitoring the integrity of the protective sheath destroys the mother code in case of an authorized access. A data processing program checks the inputted open information for presence of service symbols therein which are used as a most important tool for carrying out different cryptographic operations. Individual data of a user, including the electronic digital signature thereof, is recorded in a ROM. The inventive cryptoprotective complex comprises a user identification device in the form of an identification wristband that stores single-use access passwords.
