DETAILED DESCRIPTION

[0022] The preferred embodiments of the application will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to explain and illustrate the application, and do not limit the application.

[0023] In the application, the meanings of "inner" and "outer" refer to the direction of the storage position of the goods inside the track system of the stereoscopic storage rack, which is the inner direction, and vice versa, which is the outer direction. It is not a specific limitation of the device mechanism of the application.

[0024] The meaning of "left and right" in the present application refers to the left side of the user when the user faces the forward direction of the remote sensing device, and the right side of the user, and is not a specific limitation on the mechanism of the device of the present application.

[0025] The meaning of "connection" in the present application can be a direct connection between components or an indirect connection between components through other components.

[0026] The meaning of "up and down" in the present application refers to the direction of the track pointing to the device body when the user faces the forward direction of the remote sensing device, and vice versa, and is not a specific limitation on the mechanism of the device of the present application.

[0027] The vertical storage rack can be layered with horizontal and vertical staggered tracks, so that the four-way shuttle car 4 can run in the vertical storage rack along the horizontal or vertical track, thereby transporting goods to the appropriate storage location for storage, or transferring goods in the corresponding location to other locations in the storage system. In this storage system, different types of goods are held on standard rack pallets 5 by different containers or different fixing devices, and the four-way shuttle car runs upward to lift the rack pallet and transfer the corresponding goods to the corresponding target location.

[0028] To determine whether each rack pallet is accurately placed in its planned target location and maintained in appropriate storage conditions, the present application also provides a remote sensing device for a vertical storage system as shown. Figure 1 The remote sensing device for a vertical storage system as shown is suspended below the tracks of the vertical storage rack to monitor each pallet of goods in the next layer of the rack. The device comprises:

[0029] A drive arm is suspended below the tracks of the vertical storage system, with a drive wheel at the top end that is limited to the inside of the track, which drives the remote sensing device to run in the vertical storage system along the track groove at the bottom of the track;

[0030] A device body is fixedly connected to the bottom of the drive arm, and a wireless communication unit and a remote sensing detection device are provided on the device body. The remote sensing detection device can dynamically detect the storage conditions of the goods through any one of the following sensing units or any combination of the following sensing units:

[0031] Radar sensing system, temperature sensor, humidity sensor, pressure sensor, oxygen concentration sensor, light sensor, camera.

[0032] Referring to Figure 2 and Figure 3To ensure the above remote sensing device can be stable in the shelf track, the application preferably sets a track groove at the bottom of the lowest continuous track of each layer of shelf track in the shelf, and sets corresponding limiting guide strips 2 on the inner wall surface of both sides of the track groove along the extension direction of the track.

[0033] In cooperation with the limiting guide strips 2, the application sets two driving wheels at the top of the driving arm of the remote sensing device running in each layer of the shelf, and the two driving wheels are connected by an axle and roll along the upper surface of the two limiting guide strips 2 on both sides of the inner wall of the track groove.

[0034] To realize the power output of the above driving wheels, the application can also vertically set a chain 12 in the driving arm, the lower end of the chain 12 is connected to a driving sprocket 11 arranged in the device body, the upper end of the chain 12 is drivingly connected to a transmission sprocket arranged on the axle, the chain 12 is driven by the operation of the driving sprocket 11 to drive the transmission sprocket, so that the axle is driven by the transmission sprocket to make the driving wheels at both ends of the axle advance or retreat along the upper surface of the limiting guide strips 2. The transmission sprocket can be fixed on the outer periphery of the axle, and the outer side of the transmission sprocket can realize the limiting of the axle by two bearing structures fixed on the ends of the driving arm. The axle is provided with a through mounting hole at the end of the driving arm, the outer rings of the two bearing structures can be welded or fixed in other ways in the mounting hole at the end of the driving arm, the inner rings of the bearing structures can be connected to the axles extended from the left and right sides of the transmission sprocket, and balls are arranged between the inner and outer rings of the bearing structures to enable the axle to rotate in the direction defined by the outer ring. In this way, the bearing structure can accurately limit the rotation direction of the axle on the left and right sides of the transmission sprocket, and the driving wheels 13 at both ends of the axle can accurately fall on the limiting guide strips 2 to accurately run along the track.

[0035] To limit the deflection component of the remote sensing device relative to the track, the application further independently sets a guide groove parallel to the track groove at the bottom of the track groove in a more preferred implementation. In cooperation with the guide groove, the application further sets a guide arm above the device body, and sets a guide roller 14 capable of freely rotating in the horizontal direction at the top end of the guide arm. Thus, the guide arm extends the guide roller 14 into the guide groove, and the guide roller 14 can follow the operation of the device and roll along the guide groove corresponding to the operation of the driving wheel. Thus, the guide arm and the driving arm can be kept running along the track by two mutually parallel long groove structures, and the synchronous operation of the guide arm and the driving arm can effectively limit the rotation of the remote sensing device relative to the driving arm, thereby ensuring that the entire remote sensing device always maintains the same detection angle with the next layer of goods during movement along the track, thereby ensuring the consistency of the sampling monitoring data.

[0036] In the embodiment, the driving sprocket 11 is provided with kinetic energy by the reducer and the driving motor 10 connected therewith. The driving motor 10 is a 57BYGH56-401A stepping motor, which can provide sufficient driving torque to drive the driving wheel on the axle to rotate, and at the same time, provide accurate control of the rotation angle of the motor in the forward and reverse directions. When the motor rotates forward, the driving wheel can be driven by the driving sprocket to run forward along the track, and when the motor rotates reversely, the driving wheel can be driven by the driving sprocket to run in the other direction along the track.

[0037] In the application, the remote sensing detection device can generally be provided with a first detection surface and a second detection surface which are bent towards the center of the next layer of tracks. The first detection surface is horizontally connected at the bottom of the guide arm and the driving arm, and can provide detection signals in the vertical direction for each sensor to detect the temperature, humidity, air pressure, oxygen content and other data of the next layer of shelves. Therefore, the temperature sensor, humidity sensor, pressure sensor and oxygen concentration sensor are arranged on the first detection surface. The second detection surface can be arranged at an angle close to vertical on the outside of the first detection surface, and the angle formed by extending downward can capture the lateral detection signals of the goods in the next layer of shelves. Therefore, the radar sensing system, light sensor and camera can be installed on the second detection surface respectively to expand the detection range and realize scanning of the overall condition of the goods in the next layer of shelves.

[0038] In order to facilitate the remote sensing device to transmit various types of data obtained by detection to the warehouse system, the antenna structure in the wireless communication unit of the application is preferably arranged as follows: first horizontally extending from the top of the first detection surface, and then bending along the outside of the second detection surface to extend downward below the driving arm, so as to avoid the interference of the driving arm, track and other structures on the wireless signal.

[0039] The application can open the closing device at the end of the shelf track, insert the driving arm and the guide arm of the remote sensing detection device into the groove structure at the bottom of the track, and use the groove at the bottom of the track to provide guidance, so that the device can move back and forth in the track according to the preset mechanism for real-time inspection. Therefore, the application can update the error data and storage status in the warehouse system in real time by using the actual state of the goods in each storage position collected during the reciprocating inspection of the remote sensing device. The application enables the warehouse system to dynamically and automatically monitor the real-time state of the goods inside the warehouse system, so as to more accurately provide scheduling strategies for the goods and improve the throughput efficiency of the warehouse system.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
