The present invention provides a method, system, device and storage medium for path planning based on time expansion. The method includes: obtaining initial parameters of path planning and a two-dimensional space map; The Star path planning algorithm searches the next path node sequentially from the starting point space-time node in the three-dimensional space-time map to obtain the shortest path from the starting point to the destination. The invention can be well applied to multi-vehicle route planning, realizes vehicle anti-collision and deadlock avoidance, and at the same time satisfies the constraint of the fastest transportation plan.

A precision parts lifting and transporting device and a lifting and transporting method, the device includes a cart, a trolley, a lifting device, and a magnetic attraction device. The magnetic attraction device includes a magnetic core, steel claws, cooling pipes, air-filling pipes, and buffer components; the cooling pipe extends from the lifting arm to the magnetic core, and surrounds the outside of the magnetic core and between the steel claws to cool the magnetic core; the air-filling pipe It is connected with the buffer part and is used to fill the buffer part with high-pressure gas, so that the buffer part can generate air floating buffer between the steel claw and the precision parts. The invention can realize the avoidance of mechanical deformation and temperature deformation of the precision parts during the process of lifting and transferring, and ensure that the size of the precision parts conforms to the specification.

The invention relates to the field of the Internet, in particular to a method and system for ship collision prevention that integrates the Internet and hand-held AIS. The method includes: if both the first small ship carrying the first mobile terminal and the second small ship carrying the second mobile terminal are in an area with no Internet signal or an unstable Internet signal, starting the first AIS communication built in the first mobile terminal The module and the second AIS communication module built in the second mobile terminal, the first AIS communication module obtains the first AIS data of the first small ship, and broadcasts the first AIS data to the communication range of the first AIS communication module. When a small ship is in an area without Internet signal or an area with unstable Internet signal, turn on the first AIS communication module and use VHF to communicate with the second mobile terminal of other small ships within the communication range of the first AIS communication module to realize small ship Anti-collision.

The invention discloses a method for eliminating an idle stroke and preventing collision for grinding processing. The method is characterized in that effective grinding is divided into a black skin grinding stage, a coarse-feeding grinding stage, an enhancement grinding stage and a light-delay grinding stage, wherein idle stroke eliminating is performed by adopting fast forwarding and fast trending in idle stroke feeding before effective grinding, and a real-time current signal of a grinding wheel shaft drive motor is acquired to determine a contact state between a grinding wheel and a workpiece; fast forwarding amount and fast trending amount of the idle stroke are defined according to settings of a to-be-processed part, fast forwarding speed and fast trending speed are preset, a fast trending function test is set before the first part of the whole batch of the parts of the same specification is processed, a current value of the grinding wheel shaft drive motor is no-load current whenfast trending function test is set for forwarding, the current value of the grinding wheel shaft drive motor is set as target current when fast trending is set to be ended, target current is three times that of no-load current, and collision prevention is realized by determining whether real-time current of the grinding wheel shaft drive motor in fast trending function test reaches fast forwarding amount and fast trending amount or not for regulating target current, so that grinding efficiency and machine tool safety are improved.

The invention provides a method for carrying out mobile communication and AIS collision prevention based on a handheld AIS communication terminal. The handheld AIS communication terminal comprises an AIS processing module, a main mobile communication module, a display screen and a three-proofing module; an AIS data transceiving unit acquires AIS ship information by virtue of an AIS antenna as well as the static information and dynamic information of a local ship and the static information and dynamic information of a target ship, and the information is sent to a data processing unit through a data interface in a serial mode; the data processing unit integrates and processes the AIS ship information from the AIS processing module as well as the static information and dynamic information of the local ship and the target ship and then sends a result to a central management platform; and the central management platform carries out data fusion according to the actual business process, and thus the local ship and the target ship are guided for preventing collision. The method and the system which are provided by the invention have the advantages that an AIS function is integrated on the handheld communication terminal, so that a small ship also has a collision prevention function, the safety factor of ship navigation is improved, a marine accident is avoided, and no casualty is caused.
