The invention belongs to the technical field of aircraft passenger cabin arrangement design, and particularly relates to a passenger cabin with discontinuous longitudinal main aisles and a design method. A method for designing a passenger cabin with a discontinuous longitudinal main aisle is characterized in that a row of backward seats are arranged at the position, close to a first row of seats of a cockpit, in the passenger cabin, a row of forward seats are arranged at the position, close to the last row of seats, in the passenger cabin, the two rows of seats are the whole row of seats, and no longitudinal main aisle exists between the first row of seats and the last row of seats; other rows of seats in the passenger cabin are arranged according to 2-1 or 2-2 seats with longitudinal main aisles; seats are arranged on a longitudinal main aisle of a certain row of seats to form a whole row of seat layout, so that a passenger cabin is divided into a front compartment and a rear compartment by the whole row of seats.

This invention discloses a positioning method, system, and storage medium for inspection robots operating in long aisle corridors. It constructs a grid map of the long aisle, records the 2D laser scan profiles of the inspection robot at the beginning and end of the aisle, and the robot's current pose. Based on the robot's laser positioning system and 2D laser scanning device, it acquires the robot's real-time pose and real-time 2D laser scan frames. The difference between the robot's real-time pose and the recorded pose at the beginning of the aisle is calculated. Registration is then performed using the real-time received 2D laser scan frames and 2D laser scan profiles to determine the robot's current position. This invention solves the positioning problem of inspection robots in long aisle scenarios without increasing the robot's cost, demonstrating good adaptability to various scenarios.

The invention relates to a floor for a tread of a passageway, the tread having a base of a first material and a number of skeletons of a second material, wherein the skeletons are encased by the first material, wherein the second material has a higher modulus of elasticity than the first material and / or at least one of the skeletons has a higher hardness than the hardness of the base.

A system for use with a van having: a front seat; and a cargo area including a floor and an aisle extending rearwardly from the seat and flanked by support portions. The system comprises: panels which in use define a room having: a terminus which separates the room from the seat; a wipe clean ceiling having: a central portion overlying the aisle and flanked by strips, each overlying a support portion; for each support portion, a wipe clean flanking wall extending substantially vertically from the edge of the floor; for each flanking wall, a substantially flat, wipe clean inclined wall extending from said each flanking wall to the edge of the ceiling defined by the strip overlying the support portion for which said flanking wall is provided; a plurality of frame members which, in use, are sandwiched between the chassis and the panel members; and at least one furnishing element.

The invention discloses a walkway system of a metal composite sandwich panel roof and a construction method of the walkway system, and the walkway system comprises a support assembly and a plurality of walkway plates; the aisle plates are sequentially arranged end to end, the bottom of each aisle plate protrudes downwards to form a plurality of first mounting protrusions, the top of each aisle plate protrudes upwards to form a plurality of second mounting protrusions, and the position, corresponding to each first mounting protrusion, of the top of each aisle plate is sunken downwards to form a plurality of first mounting grooves. The positions, corresponding to the second mounting bulges, of the bottoms of the walkway plates are sunken upwards to form a plurality of second mounting grooves; the support assembly comprises support structures, the bottoms of the support structures are welded to the roof, and the first mounting protrusions of the walkway plates are supported by the tops of the support structures at the bottoms of the first mounting protrusions and detachably connected with the tops of the support structures at the bottoms of the first mounting protrusions. The situation that traditional screws penetrate through the metal composite sandwich panel roof is avoided, and the waterproof sealing performance and reliability of the metal composite sandwich panel roof are ensured.
