[0063] The lower structure of the mobile book return box is as follows: Figure 4As shown, the mobile book return box is composed of a bottom fixing frame 9, fixed casters 10 and universal casters 11. An electric push rod control panel 17, a battery 18 and an RFID tag reader 19 are installed in the lower structure of the mobile book return box by screws.

[0064] In order to realize the intelligent book return function of the mobile book return box, the embodiment of the present application also discloses an electrical control principle of the mobile book return box. Figure 5 As shown, it includes a battery, a DC / DC power supply, an Android control board, a wireless router, an RFID tag reader and a matching antenna, a book return interactive screen, a USB / 485 module, a photoelectric switch detection board and an electric push rod control board, wherein the electric push rod control board is used to control the electric push rods, and the electric push rods are numbered from 1 to n, such as 1 to 28. Optionally, when the mobile book return box also indicates the status of the books to be returned through a status indicator light, the mobile book return box also includes a photoelectric switch detection board and a status indicator light board.

[0065] The above-mentioned battery uses a 36V / 20Ah lithium battery pack. The output of the battery is converted into DC12V by a DC / DC12V power module. The DC12V power supply is used to power the Android control board, wireless router, and RFID tag reader. The DC / DC5V power module converts the output of the battery into DC+5V to provide power for the photoelectric switch detection board and the electric push rod control board. The wireless router is used to connect to the cloud library management system to realize data interaction and is connected to the Android control board through a Category 6 network cable.

[0066] In one embodiment, the photoelectric detection device is a photoelectric switch detection board, and the photoelectric switch detection board 15 includes an MCU small system, power conversion, sound and light indication, photoelectric detection, TTL232, TTL232 / RS485, and LED light control output module.

[0067] The book identification device can be a tag reader, such as an RFID tag reader, disposed on the lower structure of the mobile book return box. The tag reader scans and identifies the tag of the book to be returned, thereby determining the book information of the book to be returned, such as the book name, publisher, author information, library display shelf information, etc.

[0068] The control device may be, for example, an Android control board, which may send control commands to the electric push structure (specifically, the electric push rod control device, which will be described in detail below) through a USB / RS485 conversion module to achieve the extension and retraction of the electric push rod.

[0069] The above-mentioned electric push structure for returning books includes: an electric push rod control device, a book pushing structure, an electric push rod fixing frame, an electric push rod and a support plate; wherein,

[0070] The electric push rod control device is installed on the lower structure of the book placement structure, and the electric push rod control device is used to receive the book return control command sent by the control device to control the extension and retraction of the electric push rod;

[0071] The book pushing structure is installed in conjunction with the telescopic rod of the electric push rod to push out the books to be returned at the corresponding position;

[0072] The electric push rod fixing frame includes a vertical plate and an electric push rod fixing piece welded to the vertical plate, the electric push rod fixing piece is a group of two, the electric push rod is fixed by screws, and the electric push rod fixing frame is fixed to the upper structure of the book placement structure by screws;

[0073] The upper surface of the support plate is in an inclined state.

[0074] To understand the book return electric push structure, in a specific implementation, the book return electric push structure provided in the embodiment of the present application is shown in FIG. Figure 6 As shown, the electric push structure of the smart book return box includes a book push structure 12, an electric push rod fixing frame 13, an electric push rod 14, and a support plate 16. The book push structure 12 is made of PLA material 3D printing, and is installed with the telescopic rod of the electric push rod 14 through the groove in the middle and fixed by screws.

[0075] In an optional embodiment, the above-mentioned book return electric pusher structure includes two, and the two book return electric pusher structures are arranged in a back-to-back connection. Figure 6 With this arrangement, both sides of the mobile book return box can be used to place books to be returned, thereby facilitating readers to return books and accommodating more books.

[0076] The electric push rod fixing frame 13 is made of 3mm thick stainless steel plate welding. Figure 7As shown, the electric push rod fixing parts 71 are welded on the vertical plate, and the electric push rod fixing parts 71 are fixed to the vertical plate 72 in groups of two, and the electric push rod 14 is fixed by screws. The electric push rod fixing frame 13 is fixed to the horizontal plate 74 of the upper structure frame 1 through the screw holes 73 with screws. The support plate 16 is made of 1mm thick iron plate by bending. In order to prevent the problem of books falling when the electric push rod pushes the books, the upper surface of the support plate 16 is designed to be inclined, and the appearance is as follows Figure 8 Shown in the front view (a).

[0077] Furthermore, the bottom of the support plate 16 can be fixed with a photoelectric detection device (ie, the photoelectric switch detection board) by welding nuts 81. Figure 8 , that is, a nut 81 is welded at the bottom of the support plate 16 to fix the photoelectric switch detection board 15 .

[0078] In order to realize the in-place detection of books, a plurality of photoelectric sensor windows 82 can be arranged on the pallet, and the positions of the windows can be matched with the photoelectric sensors welded on the photoelectric detection device. Figure 8 As shown in the axonometric view (b), an LED mounting hole 83 is opened outside the inclined height of the support plate 16, and a photoelectric sensor window is opened on the support plate 16, and the position of the window matches Figure 2 The photoelectric sensor welded on the photoelectric switch detection board 15.

[0079] In an optional embodiment, an indicator light mounting plate is installed on the edge of the support plate corresponding to the outer side of the book, and a plurality of indicator light mounting holes (ie, LED mounting holes) are arranged on the indicator light mounting plate. Figure 8 As shown, each indicator light installation hole is arranged corresponding to the book pushing structure, and the indicator light installation hole is used to install the book return status indicator light. The book return status indicator light is used to turn on the indicator light reminder state when the book return electric push structure pushes out the book to be returned.

[0080] In actual application, when the book push-out structure pushes out the book to be returned, the indicator light at the corresponding position can flash, light up or other reminders to remind the staff to return the book, so that the staff can quickly identify the location of the book to be returned. When the book to be returned in the mobile book return box has been returned and put on the shelf, the indicator light stops reminding, so that the staff can confirm that the book has been returned to the right place.

[0081] The above-mentioned control device can be an Android control panel. When executing the book return function, the books in the mobile book return box may belong to multiple bookshelves. Therefore, in order to realize the full-process book return control, after the books to be returned belonging to the first target bookshelf are returned and shelved, when it is determined that the mobile book return box has moved to the second target bookshelf, the above-mentioned control device resets the electric push rod that pushes out the first target bookshelf, and sends a push-out instruction for the electric push rod corresponding to the second target bookshelf to the electric push rod control device.

[0082] The Android control board (i.e., the control device) is the control core of the mobile book return box. It realizes data exchange with the cloud library management system through a wireless network and controls the working status of the photoelectric switch detection board and the electric push rod control board through RS485.

[0083] In this way, when the mobile book return box is returning the books to be returned and shelving them, the corresponding books can be automatically pushed out to each target bookshelf for return, without the need for manual sorting. This improves the sorting efficiency of the book return process, while alleviating the tedious work costs of the staff and improving the book return efficiency and return experience.

[0084] Furthermore, the mobile book return box provided in the embodiment of the present application further includes: a book return interactive screen; the book return interactive screen is used to respond to the touch button for returning books immediately and send an immediate book return instruction to the control device. For example, regardless of whether the mobile book return box is full of books to be returned, when the "immediate book return" control is triggered through the book return interactive screen, the book return process can be executed by responding to the instruction.

[0085] In addition, in order to facilitate the staff and the users who return books to clearly and intuitively understand the book information of the mobile book return box, the above-mentioned book return interactive screen can also display the book information of the books to be returned. For example, after the user who returns the book places the book to be returned on the book placement structure of the mobile book return box, the book return information can be determined by identifying the book information, and then the book information of the book to be returned can be displayed on the book return interactive screen, so that the user who returns the book can confirm that the book has been placed in place. When the library manager wants to execute the return of the book and put it on the shelf, he can quickly understand the book information of the currently stored books to be returned through the book return interactive screen.

[0086] When the specific functions of the mobile book return box are realized, the function of the electric push rod control board is to receive the control command sent by the Android control board through the USB / RS485 conversion module to realize the extension and retraction of the electric push rod.

[0087] In one embodiment, the control program flow of the Android control panel is as follows: Fig.10As shown. After the Android control board is powered on, it is in the state of waiting for the books to be placed. When it receives the information that the books to be returned are placed in place from the photoelectric switch control board, it reads the RFID tag information attached to the books to be returned through the RFID tag reader, and binds the RFID tag information of the books to be returned with the book placement information and reports it to the cloud library management system. After receiving the binding information, the cloud library management system sends the basic information of the books to be returned, such as the title, publisher, author, etc., to the Android control board. After receiving the basic information of the books to be returned, the Android control board stores it locally and displays it on the book return interactive screen. The mobile book return box can be controlled to perform the book return task in two ways, one is to return the books immediately, and the other is to return the books after the book return box is full. Immediate book return can be achieved by touching the button of the mobile book return interactive screen or issuing commands from the cloud; return the books after the book return box is full. When the smart book return box detects that the books placed have reached the specified book threshold, it sends the full status of the book return box to the cloud. Regardless of whether the books are returned immediately or after the book return box is full, the Android control board will send a request to the cloud library management system to dispatch the AMR consignment robot. After receiving the dispatch command, the AMR transport robot lifts the mobile book return box off the ground and carries the mobile book return box to walk. According to the path planned by the cloud library management system, the AMR transport robot stops in front of the target bookshelf where books need to be put on the shelves. The Android control board receives the information of the books to be put on the shelves from the cloud library management system. After retrieving the local stored information, it sends a command to light up the indicator light of the corresponding position of the book to the photoelectric switch detection board and sends a book push command to the electric push rod control board. At this time, the books to be returned in the mobile book return box that need to be put on the target bookshelf are pushed out a certain distance, and the indicator light of the book placement position is lit. When the books to be returned in the smart book return box that belong to the target bookshelf are put on the shelves by the staff, the AMR transport robot transports the mobile book return box to another target bookshelf that needs to be parked, sends a command to light up the indicator light of the corresponding position of the book to the photoelectric switch detection board, sends a book push command to the electric push rod control board, and waits for the staff to put the books on the shelves. At the same time, the indicator light that was lit at the previous parking point is turned off and the pushed electric push rod is reset. When the staff takes the books to be returned and puts them on the shelves, if the books to be returned do not belong to the books, the Android control board will send a wrong taking instruction to the photoelectric switch detection board after judgment. The photoelectric switch detection board will make the indicator light corresponding to the wrong book to be returned flash. When the wrong book to be returned is put back to its original position, the photoelectric switch detection board will turn off the flashing indicator light. When all the books to be returned in the mobile book return box are put on the shelves, all the indicator lights will be turned off, all the electric push rods will be reset, the book return task will be completed, and the mobile book return box will be transported to the starting point by the AMR consignment robot and placed on the ground, completing a workflow.

[0088] The control process of the electric push rod control panel is as follows Fig.11 As shown. After the electric push rod control board is powered on and initialized, all the electric push rods are reset. When receiving the push command sent by the Android control board, the output states of the two I / O ports corresponding to the microcontroller are changed from 00 to 01, so that the corresponding push rods are pushed forward. After a certain delay, the output states of the two I / O ports are changed from 01 to 00, and the electric push rods stop pushing forward and maintain; when receiving the reset command sent by the Android control board, the output states of the two I / O ports corresponding to the microcontroller are changed from 00 to 10, so that the corresponding push rods are pushed forward. After a certain delay, the output states of the two I / O ports are changed from 10 to 00, and the electric push rods stop pushing forward and maintain.

[0089] In summary, this application realizes the sorting function of books to be returned during intelligent book return through the book push-out structure. According to the different book return points, the books to be returned can be clearly specified by the on and off status of the LED light and whether the electric push rod pushes the books to be returned. If there is a pick-up error during the shelving of the books to be returned, the LED at the corresponding position can be flashed to remind. In addition, the branch antenna book stand separation design and sorting function can save the staff from the process of searching when returning books to the shelves, thereby improving work efficiency.
