The invention provides a large-scale industrial data compression storage method, system and medium, including: step 1: configuring different data acquisition systems according to the type of data source, and extracting the data collected by the data acquisition system through interface operation; step 2 : Define the conversion chain, and temporarily convert the format of different types of data extracted into Avro format through the data cleaning plug-in; Step 3: Compress the data in Avro format with the GPL protocol, and the compression format is snappy, and create the following in the distributed file system Parquet is a data set in a storage format, which stores compressed data. The invention can define conversion chains and compression and storage formats for any type of data, greatly improving the data processing speed and data compression ratio of the computing platform.

The invention discloses a method and system for correcting the take-off and landing course of an unmanned aerial vehicle, and relates to the technical field of take-off and landing of an unmanned aerial vehicle, including a method for correcting a take-off course and a method for correcting a landing course. The method for correcting the take-off course comprises the following steps: Step 1: Open the top cover of the machine nest and obtain the initial direction north east α1 angle of the rotating platform and the wind direction information north east β angle, step 2: The rotating platform calculates the take-off heading correction angle of the UAV according to the difference θ=β‑α1; step 3: When the rotating platform rotates to the difference |θ|=β‑α1<1°, send the take-off command to the drone through the nest; Step 4: After the drone receives the take-off command, follow the standard take-off process, The take-off process is completed; the course correction strategy of the method of the present invention is implemented in the control structure of the machine nest, which can make the course of the unmanned aerial vehicle in the windward position when the unmanned aerial vehicle is ready to take off, and maximize the use of the resistance of the unmanned aerial vehicle during take-off. wind performance.

The invention discloses a UAV landing aid system with wireless ultraviolet light on the ship surface, which includes an information processing center, and the information processing center is respectively connected with an integrated transceiver device, an environmental sensor and a state sensor, and the integrated transceiver device is respectively installed on the edge of the allowed landing area on the deck corners and drone bottom. The invention also discloses a UAV landing aid guidance method with wireless ultraviolet light on the ship surface. The invention solves the problems that the existing unmanned aerial vehicle landing aid system is greatly affected by the climate environment, the successful landing rate is not high, there is electromagnetic interference, and the equipment is complicated.

The present disclosure relates to a UAV landing control method, device, storage medium and electronic equipment, the method comprising: in response to receiving a landing request of a target UAV, acquiring the flight information of the previous UAV, wherein the The preceding drone is a drone that shares the same parking platform with the target drone, and the flight information includes the moment when the preceding drone leaves the parking platform after landing; and, it is determined The target space sub-area where the target UAV is located in the landing airspace corresponding to the parking platform, wherein the landing airspace includes a plurality of non-overlapping space sub-areas; When leaving the parking platform, control the target drone to land on the parking platform through the target space sub-area according to the flight information, so that the target drone lands on the parking platform The time of is later than the time when the pre-sequence unmanned aerial vehicle leaves the parking platform.

The invention discloses a rapid taking-off and landing device of an air vehicle. The rapid taking-off and landing device comprises an onboard device and a vehicle-mounted device, wherein the onboard device is arranged at the bottom of the air vehicle, and comprises a landing convex seat, an electric winch, a pulling rope, a cord weight, a dragging ball, a ball ejector, a photoelectric receiver and a taking-off and landing controller; the vehicle-mounted device is arranged at the top of a vehicle and comprises a landing concave ground, a ball falling hole, a locking device, a detection feedback device and a photoelectric transmitter; the landing convex seat of the onboard device and the landing concave ground of the vehicle-mounted device are in a funnel shape with an upward opening, and can be embedded and matched. The taking-off and landing controller can realize rapid and accurate capturing and dragging of the landing platform moving on the ground by the air vehicle according to a photoelectric signal state without human intervention, and the reliability of the taking-off and landing as well as the transportation and fixing of the air vehicle are guaranteed.

The invention relates to an integral hoisting process of a ship unloader. The integral hoisting process comprises the following steps: preparation before hoisting: after general assembly debugging of the ship unloader, dismounting front girder components and dividing the ship unloader into two parts for shipping; hoisting preparation of door frame, rear girder and machine room components: firstly, lightering the components to a dock A to stop, and well threading wire cables and well mounting shackles; hoisting of the door frame, rear girder and machine room components: hoisting with two main hooks of a floating crane and hoisting the components to be above an appointed track; laying the door frame, rear girder and machine room components on a track: during the process for laying the components on the track, using a chain block to protect a cart; preparation before hoisting of the front girder components; and hoisting of the front girder components (namely, general assembly of the ship unloader): well mounting the hoisting wire cables, hoisting a front girder to an appointed height to be parallel and level with a rear girder, mounting a front and rear girder hinge shaft, well threading a front girder pitching wire cable, and well connecting a front pull rod to complete hoisting of the front girder. The integral hoisting process has the advantages that the ship unloader can be used so long as slight debugging after electrifying is performed, so that manpower and material resources for on-site general assembly are saved, the integral disembarking efficiency is improved and the cost is lowered.
