[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] A preferred embodiment of the present invention is a safe cabinet with multiple groups of RFID antenna components; Figure 1-2 As shown, it includes a cabinet 10, with a set of side panels 18 provided on each of the left and right sides of the cabinet. The side panels are provided with multiple groups of support columns 180, and partitions 19 are installed on the support columns, some of which are connected to antenna assemblies 20 at their lower ends, and antenna assemblies 20 are also provided on the top of the inner wall of the cabinet, thereby forming multiple groups of antenna assemblies inside the cabinet. The cabinet 10 is open on one side, and the opening is connected to a left door 11 and a right door 12. The left door and the right door can be opened independently, and the cabinet is closed when they are closed at the same time. A maintenance door 14 is provided on the side of the cabinet, and a circuit module 25 is installed in the maintenance door. The maintenance door facilitates the maintenance and replacement of the circuit module, and the circuit module controls the operation of the antenna assembly to obtain information and related communications. In order to facilitate the placement of the safe, a support assembly 13 is provided at the bottom of the cabinet 10, and the safe can be moved and supported by the support assembly.

[0031] Specifically, such as Figure 2-3 and Figure 5 As shown, light strip assemblies 17 are provided on the left and right sides of the cabinet 10 near the left and right doors. When the left door 11 or the right door 12 is opened, the light strip assembly on the corresponding side can emit light. The light strip assembly 17 includes a light strip bracket 170 connected to the cabinet. The left and right sides of the light strip bracket are provided with convex edges 174. A recessed groove 173 is formed between the two sets of convex edges. A light strip 171 is placed in the recessed groove, and a light board 172 is provided above the light strip bracket. After the light strip is illuminated, it illuminates the light board. Since the light strip bracket is vertically distributed in the cabinet, it plays a certain supporting role for the cabinet. The light strip is placed in the recessed groove to improve the scattering of the light strip after the light is emitted, and the lighting effect is better. The convex edges 174 on both sides also further enhance the strength of the light strip bracket.

[0032] Further, if Figure 2-3 and Figure 6As shown, side plates 18 are provided on both the left and right sides of the inner wall of the cabinet body 10. The side plates are overall in a U-shaped form, which includes support side plates 181 and support columns 180 provided on the two groups of support side plates. The support columns are located on the opposite faces of the two support side plates. The partition can be placed on the two groups of opposite support columns, and the partition can be taken out by tilting it after lifting. An antenna assembly is connected below the middle partition, so that the antenna assembly is kept parallel to the partition, shortening the signal propagation path and reducing interference at the same time, thereby improving the signal coverage effect and recognition rate. The antenna assembly can adopt a UHF RFID antenna assembly, which includes an antenna unit, helping to ensure the uniform distribution and omnidirectional coverage of the signal, and the UHF RFID antenna assembly has a higher-sensitivity RFID antenna, enabling the safe cabinet to accurately identify and track RFID tags in a complex environment. At the same time, the antenna assembly should be set with the same spacing as much as possible in the up, down, left, and right directions and be installed in the center to make its signal coverage more comprehensive. And a hollow cavity 182 is formed between the support side plate and the inner wall of the cabinet body. A vertical column 183 is provided in the hollow cavity. The vertical column extends from the upper end of the support side plate to the lower end of the support side plate, thereby providing a certain supporting force to the upper end of the cabinet body, increasing the strength of the cabinet body, and at the same time improving the strength of the support side plate, so that more items can be placed on each partition without causing the deformation of the support side plate. At the same time, due to the hollow cavity formed between the cabinet body and the support side plate, the safe cabinet also has a certain shock absorption property. When the cabinet body is vibrated, the hollow cavity absorbs the vibration of the cabinet body, preventing the vibration from being transmitted to the support side plate and then to the partition. And wiring can be carried out in the hollow cavity, facilitating the connection and installation of the circuit module and the antenna assembly. The UHF RFID antenna assembly uses the principle of electromagnetic wave radiation and reception to realize the identification and data transmission of RFID tags. Through the reasonable layout of two sets of antennas, it ensures the uniform distribution and omnidirectional coverage of the signal, improving the recognition rate and accuracy.

[0033] Further, as Figure 1 、 Figure 7 and Figure 10-12As shown, the right door 12 includes an outer door sheet metal 122 and an inner door sheet metal 121. A gap is left between the outer door sheet metal and the inner door sheet metal, and a display screen 120 is provided on the outer door sheet metal. The display information of the circuit module can be viewed through the display screen, and corresponding operations can also be performed, such as entering a password to unlock, changing the unlock password, etc. A locking member 125 is provided on the side of the right door, and an electric suction column 126 is connected to the locking member. The electric suction column passes through the upper end of the right door and can be locked into the right door, and can be moved by operating the electric suction column through the handle 124. An electric suction column fixing hole 27 is provided on the top of the cabinet corresponding to the electric suction column, and a door suction motor 29 is provided above the electric suction column fixing hole. When the door suction motor is powered off after unlocking, the handle can be turned to rotate the electric suction door out of the electric suction column fixing hole to open the right door. After the handle is turned to rotate the electric suction column into the electric suction column fixing hole, the door suction motor automatically locks and locks the right door. The upper and lower ends of the right door are rotatably connected to the cabinet body via a rotating shaft 123, so that the right door can be rotated relative to the cabinet body to open or close the right door. The left door and the right door have the same structure, except that the left door does not have a display screen. The other structures are the same as the right door, so they will not be repeated here.

[0034] Furthermore, if Figure 2-4 As shown, the support assembly 13 includes a foot support 131 connected to the cabinet body and an adjustment nut 130 for adjusting the height of the foot support. The height of the foot support can be adjusted by turning the adjustment nut. The support assembly also includes casters 132. When the safe needs to be moved, the lower end of the foot support can be turned higher than the lower end of the caster to achieve movement, making movement easier. After moving to a desired position, the adjustment assembly can be turned so that the lower end of the foot support is higher than the lower end of the caster to secure the safe, providing greater stability and convenient adjustment.

[0035] Furthermore, if Figure 8-12As shown, the inner wall of the cabinet 10 is provided with multiple groups of support plates 21, and the support plates are provided on the back, bottom, top and sides of the cabinet to improve the strength of the safe. At the same time, a maintenance door 14 is provided on the side corresponding to the circuit module 25. The circuit module can be replaced and repaired by opening the maintenance door. An operation port 28 is provided on the back side of the cabinet, which is provided with a communication interface 22 and a socket 23. The safe is connected to the power supply through the socket to make it work. The switch 24 controls the opening and closing of the safe and transmits communication through the communication interface. A camera 26 is provided on the top of the safe. The camera and antenna assembly are both provided on the top of the cabinet and are hidden by a light-transmitting plate 200. The light-transmitting plate allows the antenna assembly and the camera to work normally. A top cover door 15 is provided on the top of the cabinet body. When the top cover door is opened, two sets of shielding lamp assemblies 16 are provided inside. The shielding lamp assemblies are mounted on the cabinet body through shielding lamp brackets and are provided with shielding lamp covers 160. The shielding lamp assemblies can be replaced by opening the top cover door. At the same time, the battery box 31 and the debugging box 30 that match the antenna assembly can also be replaced by opening the top cover door, which makes the operation more convenient. The setting of the shielding lamp enhances the anti-interference ability of the safe, so that the safe can work normally in an environment with other electromagnetic interferences, ensuring the stability and reliability of the signal. The circuit module 25 can adopt intelligent management, such as automatic alarm, log recording, etc. to improve the security and management efficiency of the safe. At the same time, in order to further reduce the obstruction and reflection of RFID signals, non-metallic materials are preferably used as the layer material and support. The cabinet body and side panels need to be made of metal material, and the width of the metal frame should be kept within 3 cm as much as possible to balance the support strength and signal transmission requirements.

[0036] It should be understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
