[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Combine the following Figure 1-Figure 7 The utility model is described in detail.

[0026] Figure 1 It is a structural schematic diagram of a fire extinguisher cabinet provided by the utility model.

[0027] like Figure 1 As shown, the fire cabinet 10 includes: a main cabinet 11, and a wireless radio frequency identification RFID reader 12 ( Figure 1 at least one sub-cabinet 13, in which an RFID antenna 14 and a multi-degree-of-freedom pan / tilt 15 are arranged.

[0028] like Figure 1 As shown, the multi-degree-of-freedom pan / tilt head 15 in each sub-cabinet 13 includes a rotating end 151 and a fixed end 152 .

[0029] The rotating end 151 is connected to the RFID antenna 14 located in the same sub-cabinet 13 .

[0030] The fixed end 152 is fixed to the inner wall of the sub-cabinet 13 where it is located, and the fixed end 152 is used to fix the multi-degree-of-freedom pan / tilt head 14 in the sub-cabinet 13 where it is located.

[0031] The fixed end 152 may be fixed to the top wall of the sub-cabinet 13 where it is located, or to the side wall of the sub-cabinet where it is located, or to the bottom surface of the sub-cabinet 13 where it is located.

[0032] like Figure 1 As shown, the fixed end 152 can be fixed at the center position of the top wall of the auxiliary cabinet 13 where it is located.

[0033] The multi-degree-of-freedom gimbal 15 may be, for example, a two-degree-of-freedom gimbal, a three-degree-of-freedom gimbal, or the like.

[0034] Take the multi-degree-of-freedom gimbal 15 as an example of a two-degree-of-freedom gimbal. Figure 2As shown, the two-degree-of-freedom platform 21 can rotate along a first direction or a second direction, and the first direction is perpendicular to the second direction.

[0035] The rotation axis of the two-degree-of-freedom gimbal may include a horizontal rotation axis and a vertical rotation axis. In this case, the first direction is the horizontal direction and the second direction is the vertical direction.

[0036] It is understandable that, according to the volume of the sub-cabinet, the matching of the antenna scanning area and other requirements, the sub-cabinet can be equipped with a small number of auxiliary antennas to expand the scanning area, improve the scanning accuracy or improve the scanning efficiency.

[0037] See also Figure 3 At a certain moment, the rotation end position of the two-degree-of-freedom platform 21 is as follows: Figure 3 As shown, in this case, the RFID antenna ( Figure 3 The scanning range (not shown) is as follows Figure 3 The arrow in the middle points to the range.

[0038] The two-degree-of-freedom gimbal can be driven by a motor or a servo, and its movement angle and speed can be adjusted according to the signal characteristics of the RFID.

[0039] Combination Figure 1 , Figure 2 and Figure 3 The rotating end is connected to the RFID antenna in the same sub-cabinet. When the rotating end rotates, the RFID antenna is also driven to rotate. The scanning area of ​​the RFID antenna can extend to the entire space of the sub-cabinet, thereby minimizing the blind area of ​​the RFID antenna scanning.

[0040] Based on the design of the multi-degree-of-freedom gimbal, the blind area of ​​the RFID antenna scanning is reduced. In this case, the number of RFID antennas that originally need to be installed in a sub-cabinet can be reduced from 4-8 to 1, effectively reducing the number of RFID antenna layouts. At the same time, it can also ensure that the RFID antenna scanning area can cover the entire space in the cabinet where it is located, ensuring that all items in the cabinet can be scanned.

[0041] See also Figure 3 The bracket 211 connected to the RFID antenna in the two-degree-of-freedom pan-tilt head 21 is a non-metallic bracket to avoid interference with the signal of the RFID antenna 14.

[0042] See also Figure 1 The RFID antenna 14 in each sub-cabinet 13 is coupled to the RFID reader 12 in the main cabinet, and the RFID reader 12 is used to read the scanning signal obtained by the RFID antenna 14 scanning the items in the sub-cabinet.

[0043] Combination Figure 1 and Figure 4As shown, the RFID antenna 14 is electrically connected to the RFID reader 12 via a feeder 41 , and signals are transmitted between the RFID antenna 14 and the RFID reader 12 via the feeder 41 .

[0044] In some embodiments, the fire cabinet 10 further includes: a central controller ( Figure 1 not shown).

[0045] The central controller is coupled with the multi-degree-of-freedom pan-tilt platform, and the central controller is coupled with the RFID reader / writer.

[0046] The central controller is used to control the rotating end of the multi-degree-of-freedom pan / tilt in the target sub-cabinet to move along a set motion trajectory before controlling the target sub-cabinet to open or after detecting that the target sub-cabinet is closed, and at the same time control the RFID antenna in the sub-cabinet to start scanning through the RFID reader / writer; the target sub-cabinet is any one of at least one sub-cabinet.

[0047] The central controller is also used to: receive a scanning signal obtained by scanning the items in the target sub-cabinet and sent by the RFID antenna in the target sub-cabinet through the RFID reader / writer, and obtain the item information in the target sub-cabinet according to the scanning signal.

[0048] In some embodiments, the above working process of the central controller is specifically as follows.

[0049] First, the central controller determines the target sub-cabinet where the target item is located according to the signal received from the user indicating the target item to be taken. Before controlling the target sub-cabinet to open, the central controller controls the multi-degree-of-freedom pan-tilt in the target sub-cabinet to move along a set motion trajectory, and at the same time controls the RFID antenna connected to the rotating end of the multi-degree-of-freedom pan-tilt in the target sub-cabinet to start scanning through the RFID reader / writer. The RFID antenna continuously changes the scanning area with the movement of the rotating end of the multi-degree-of-freedom pan-tilt, scans the items in the entire target sub-cabinet space, and obtains set A. Then the central controller controls the door of the target sub-cabinet to open, and the user takes the item and closes the door. After the central controller detects that the door of the target sub-cabinet is closed, it controls the multi-degree-of-freedom pan-tilt to move along the set motion trajectory again, and at the same time controls the RFID antenna connected to the rotating end of the multi-degree-of-freedom pan-tilt in the target sub-cabinet to start scanning through the RFID reader / writer, and scans the items in the entire target sub-cabinet space again to obtain set B.

[0050] The central controller obtains the complement of set B with respect to set A, and obtains set C, where C is the taken items, thereby obtaining the taken items in the target sub-cabinet.

[0051] Similarly, when a user wants to put an item into the smart fire cabinet, the central controller can also determine the target sub-cabinet corresponding to the item based on the item put in, and then perform the above operation of obtaining set C, thereby obtaining the item put in the target sub-cabinet.

[0052] It can be seen that the smart fire cabinet can automatically complete the registration of items in and out of the warehouse. After that, the central controller can also report the item information to the cloud so that the administrator can remotely obtain the item information in the fire cabinet and check for omissions in the smart fire cabinet.

[0053] In a specific implementation, an electromagnetic lock is provided on the sub-cabinet of the fire cabinet, and the central controller is coupled to the electromagnetic lock, and the cabinet door of the sub-cabinet is controlled to be opened by controlling the electromagnetic lock to be opened.

[0054] In some embodiments, as shown in the figure, a multi-layer shelf support arm 131 is provided on the side wall of the sub-cabinet 13, and the fire cabinet 10 also includes at least one adjustable shelf 16, and each shelf support arm 131 is used to place an adjustable shelf 16. The adjustable shelf 16 is made of non-metallic material. The user can place multiple adjustable shelves in the sub-cabinet according to his needs to divide the space in the sub-cabinet and reasonably utilize the space in the sub-cabinet.

[0055] In the utility model, the number of sub-cabinets can be adjusted and combined according to the number of fire-fighting articles, and the number of adjustable shelves in the sub-cabinets can be adjusted according to the types and quantities of the fire-fighting articles.

[0056] In some embodiments, the fire cabinet 10 further includes: at least one identity information collection device disposed on the outer surface of the main cabinet.

[0057] The identity information collection device is coupled to the central controller and is used to collect identity information. In this case, the central controller is also used to: receive identity information from the identity information collection device; and control the opening of the cabinet door of the sub-cabinet according to the identity information.

[0058] In some embodiments, the identity information collection device includes at least one of the following: a face recognition camera, a fingerprint collector, and a card reader.

[0059] like Figure 5 As shown, the identity information collection device includes a face recognition camera 51, a fingerprint collector 52, and a card reader 53.

[0060] The face recognition camera 51 is used to collect face information, and the fingerprint collector 52 is used to collect fingerprint information.

[0061] The card reader 52 is used to read the use authority information of the fire cabinet, such as the card information on the use authority card, the QR code information related to the use authority, etc.

[0062] The identity information collection device is coupled with the central controller, and the collected identity information can be sent to the central controller, and the central controller authenticates the user based on the collected identity information, so that the smart fire cabinet can authenticate the user who takes the item through card swiping, code scanning, fingerprint recognition and face recognition.

[0063] In some critical situations, such as fire rescue in critical situations, it is necessary to quickly open the doors of all the sub-cabinets storing firefighting items to take out the firefighting items. Based on the above requirements, the intelligent fire fighting cabinet in the utility model also includes: an alarm module.

[0064] The alarm module is coupled to the central controller and is used to control the doors of all sub-cabinets to open after receiving the alarm signal. For example, after receiving the alarm signal, the alarm module can send a forced cabinet opening signal to the central controller, and the central controller controls the doors of all sub-cabinets to open according to the forced cabinet opening signal.

[0065] When sending an alarm signal to the alarm module, the administrator can send the alarm signal to the alarm module through a remote terminal to remotely control the opening of the doors of all sub-cabinets of the intelligent fire cabinet; or the administrator can send an alarm signal to the alarm module locally (for example, an alarm button is set on the main cabinet, and the user can press the alarm button in an emergency) to control the opening of the doors of all sub-cabinets of the intelligent fire cabinet.

[0066] In some embodiments, the smart fire cabinet further includes: a rain cover disposed above the exterior of the main cabinet and the auxiliary cabinet.

[0067] like Figure 6 As shown, the rain cover 61 on the outside of the main cabinet 11 and the auxiliary cabinet 13 can be used to block rain and wind, etc., to facilitate the maintenance of the fire cabinet and prevent the fire cabinet from malfunctioning due to being wet by rain.

[0068] In some embodiments, the smart fire cabinet further includes: at least one lighting lamp, and the at least one lighting lamp is arranged on a side of the rain cover facing the main cabinet and the auxiliary cabinet.

[0069] like Figure 7 As shown, four lighting lamps 71 are arranged on one side of the rain cover 61 facing the main cabinet and the auxiliary cabinet, which can be used for lighting at night or in poor light conditions to capture the status of fire-fighting items in the cabinet around the clock.

[0070] In some embodiments, the smart fire cabinet further includes: at least one surveillance camera, and the at least one surveillance camera is disposed on a side of the rain cover facing the main cabinet and the auxiliary cabinet.

[0071] like Figure 7As shown, two monitoring cameras 72 are also provided on the side of the rain cover 61 facing the main cabinet and the sub-cabinet, which can collect images of a set area around the fire cabinet (the position of the monitoring camera can be set according to the set area to be collected), so that when an RFID misreading occurs, the item information can be traced based on the image collected by the monitoring camera.

[0072] In some embodiments, the smart fire cabinet further includes a display screen, which is disposed on the main cabinet of the smart fire cabinet and is used to play videos or images.
