[0022] like Figure 2 As shown, the multiple book storage grids are specifically four book storage grids, including a front grid and a back grid located on the front and back of the device, and the front grid and the back grid respectively include two grids located on the upper and lower layers, that is, there are two layers of grids in total, and each layer has two book storage grids 100. Figure 1The structures in the upper layer and the connection mode of the structures in the front of the device are shown in the figure.
[0023] Referring to Figure 1 and Figure 2 The device has four grids, each grid 100 has a lock driver 110 and a power divider 120, that is, there are four lock drivers 100 and four power dividers 120, and the connection mode is as follows:
[0024] The first lock driver and the second lock driver are respectively the drivers of the cabinet door locks in the upper and lower layers of the front grid of the device, wherein the first lock driver drives the opening of the 1# cabinet door lock, the 2# cabinet door lock, the 3# cabinet door lock, the 4# cabinet door lock, the 5# cabinet door lock, the 6# cabinet door lock, the 7# cabinet door lock, the 8# cabinet door lock and the 9# cabinet door lock through the driving lines L1, L2, L3, L4, L5, L6, L7, L8 and L9 respectively. The second lock driver drives the opening of the 10# cabinet door lock, the 11# cabinet door lock, the 12# cabinet door lock, the 13# cabinet door lock, the 14# cabinet door lock, the 15# cabinet door lock, the 16# cabinet door lock, the 17# cabinet door lock and the 18# cabinet door lock through the driving lines L10, L11, L12, L13, L14, L15, L16, L17 and L18 respectively.
[0025] The third lock driver and the fourth lock driver are respectively the drivers of the cabinet door locks in the upper and lower layers of the back grid of the device, wherein the third lock driver drives the opening of the 19# cabinet door lock, the 20# cabinet door lock, the 21# cabinet door lock, the 22# cabinet door lock, the 23# cabinet door lock, the 24# cabinet door lock, the 25# cabinet door lock, the 26# cabinet door lock and the 27# cabinet door lock through the driving lines L19, L20, L21, L22, L23, L24, L25, L26 and L27 respectively. The fourth lock driver drives the opening of the 28# cabinet door lock, the 29# cabinet door lock, the 30# cabinet door lock, the 31# cabinet door lock, the 32# cabinet door lock, the 33# cabinet door lock, the 34# cabinet door lock, the 35# cabinet door lock and the 36# cabinet door lock through the driving lines L28, L29, L30, L31, L32, L33, L34, L35 and L36 respectively.
[0026] The first power divider and the second power divider are respectively installed in the upper and lower layers of the front grid of the device, the first power divider is respectively connected to the antennas 1, 2, 3, 4 and 5 through the first radio frequency feed lines R1, R2, R3, R4 and R5 one by one, and the second power divider is respectively connected to the antennas 6, 7, 8, 9 and 10 through the first radio frequency feed lines R6, R7, R8, R9 and R10 one by one.
[0027] The third power divider and the fourth power divider are respectively installed on the upper and lower layers of the back grid of the device. The third power divider is connected to the antennas 11, 12, 13, 14, and 15 through the first radio frequency feed lines R11, R12, R13, R14, and R15 one by one respectively. The fourth power divider is connected to the antennas 16, 17, 18, 19, and 20 through the first radio frequency feed lines R16, R17, R18, R19, and R20 one by one respectively.
[0028] Referring to Figure 2 The RFID reader 200 is connected to the four power dividers 120 through the second radio frequency feed lines R21, R22, R23, and R24 one by one respectively. The power dividers 120 divide the signal output by the RFID reader 200 into five equal parts and output them to the five antennas connected to the power dividers 120 respectively.
[0029] Referring to Figure 2 The device further comprises a robot chassis controller (the controller of the robot itself), which is connected to all the lock drivers 110, i.e., the first lock driver, the second lock driver, the third lock driver, and the fourth lock driver, and the RFID reader 200 through the communication lines X1, X2, X3, X4, and X5 one by one respectively.
[0030] Specifically, when a user needs to take away a reserved book in one of the cabinets, the user inputs the cabinet number through the operation interface. Then, the robot chassis controller sends an opening instruction to the lock driver 110 of the corresponding layer of the cabinet door where the book is placed. Then, the lock driver 110 of the layer drives the cabinet door lock of the cabinet door where the book is placed to open the cabinet door, so that the user can take away the reserved book and close the cabinet door. After the cabinet door is closed, the on-off state of the cabinet door lock is sent to the lock driver 110 of the layer. Then, the lock driver 110 returns the state signal of the closed cabinet door to the robot chassis controller. The robot chassis controller can obtain the state information that the cabinet door has been opened and closed.
[0031] When the user clicks the desired reserved book or its corresponding cabinet on the operation interface, the robot chassis controller sends a query instruction (querying the specific layer of books) to the RFID reader 200, the RFID reader 200 executes the query instruction, switches the radio frequency signal to the power divider 120 of the corresponding layer, the power divider 120 divides the radio frequency signal to the 5 antennas of the layer, the layer antenna transmits the sensed RFID tag information pasted on the book to the RFID reader 200, the RFID reader 200 transmits the sensed RFID tag information pasted on the book of the layer to the robot chassis controller again, and compares the sensed RFID tag information with the stored book information of the last layer (obtains the current book storage information), takes away the reserved book and sends the reserved book to the robot chassis controller, and updates the current book storage information.
