5results about How to "Solve the low positioning accuracy" patented technology

The utility model discloses a kind of quick-mounting live joint valves, it is related to pipeline connection and control equipment technical field, including first docking pipeline, link chamber and second docking pipeline, the first docking pipeline is communicated with second docking pipeline, the link chamber is fixedly installed at the junction of first docking pipeline and second docking pipeline, the top of the link chamber is communicated with containing room, the utility model is connected by being set by third docking pipeline, first limit ring, second limit ring, link rod, boss, extension block, quick-mounting mechanism, without welding, hot melting or multiple bolt fastening, only by aligning limit convex strip, sleeve joint limit ring and rotating link rod can be completed fast connection, greatly simplify installation and disassembly process, reduce operation difficulty and labor cost, simultaneously adapt to various industry pipeline systems, solve the problem that traditional valve installation is complicated, disassembly damages pipeline and part quick-mounting valve positioning accuracy is low.

The application belongs to the field of positioning, and particularly relates to a submerged load distributed ultra-short baseline positioning system and a positioning method. The application discloses a submerged load distributed ultra-short baseline positioning system and a robust positioning method thereof, which effectively overcomes the problem that the positioning results of a traditional ultra-short baseline positioning system are inconsistent under limited observation space and different array patterns. By arranging acoustic elements at multiple positions on the surface of a submarine, a distributed acoustic array is formed, and the observation space of the submarine is expanded. Meanwhile, a robust positioning method is proposed by introducing azimuth constraints, and the robustness of the acoustic positioning result to array changes is enhanced. Through the application, the observation of the acoustic array on the submerged load to a target in the whole space can be realized, and stable positioning accuracy can be maintained when part of the acoustic elements fail.

The utility model relates to positioning device technical field discloses a kind of positioning device of PIN-free positioning board, including workbench, the workbench top surface is provided with pneumatic cylinder, the utility model is rotated by motor driving transmission shaft and gear, make two groups of gear synchronous action on two groups of first rack and second rack, make two groups of first rack and second rack in first sliding slot and second sliding slot opposite direction sliding, and make first rack and second rack synchronous drive clamping plate in first guide slot and second guide slot sliding, to reach the purpose of printed circuit board workpiece fast clamping, again match CCD camera to the position of circuit board carries out electricity measurement, to improve the positioning accuracy of circuit board, while effectively solve the problem that only relying on visual identification or mechanical position is carried out in prior art, leading to low positioning accuracy.

The invention discloses a remote real-time monitoring system for racing boat training, and the system comprises an MCU processor, a data collection module, a data storage module, a data positioning module, a data transmission module, an alarm module, a display screen, and a cloud server. The data acquisition module and the data positioning module are in two-way communication with the MCU processor through the data transmission module, and the MCU processor is in two-way communication with the data storage module, the alarm module and the display screen; according to the invention, when a racing boat is carried out, field equipment does not need to be arranged in advance, and the current condition of the racing boat can be conveniently and dynamically known ashore by using a tablet computer or a computer as a training guidance basis; meanwhile, the position information is sent in real time, so that relatively intuitive watching experience can be provided; meanwhile, due to linkage of GPS and 4G, sub-meter positioning information is provided through RTK differential positioning, and the positions and real-time change conditions of all racing boats can be accurately displayed.

The utility model relates to the technical field of machine vision and automation control, in particular to a vision positioning structure for penicillin bottle positioning, which comprises a camera, a fixing shell, a fixing ring, an annular illuminating lamp, a fixing component and an adjusting mechanism, the fixing shell is in bolted connection with the camera and covers the outer side of the camera, the fixing ring is arranged on the outer side of the camera, and the annular illuminating lamp is arranged on the fixing component. The annular illuminating lamp is in bolted connection with the fixing ring and located below the fixing ring, the fixing assembly is arranged on one side of the fixing shell, and the adjusting mechanism is arranged below the fixing assembly. And the positioning precision is low.
