AI Technical Summary
The existing smart security box has insufficient security in password and fingerprint unlocking methods, and the UWB distance measurement distance is limited, and it is impossible to measure the distance exceeding 60 meters.
UWB digital key circuit is used to authenticate and roughly position the identity through Bluetooth. After getting close to the safety box, it uses the UWB anchor point for real-time ranging and positioning. After pressing the unlock button, the digital key sends an unlocking signal. The UWB antenna of the motherboard receives and processes it and outputs a high level to drive the motor to open the box cover.
It realizes the safe opening of the smart security box at a long distance, avoiding the risk of passwords and fingerprints being easily stolen, and expanding the UWB distance measurement distance to 60 meters.

Description
Technical Field
[0001] The utility model relates to the technical field of UWB digital key circuits, in particular to a safe intelligent box with a UWB digital key unlocking circuit. Background Art
[0002] Smart security boxes are box equipment that integrates modern information technology and security protection functions. They are designed to improve the security of item storage, intelligent monitoring, and efficient management. Such equipment is widely used in homes, businesses, industries, and specific professional fields, such as video surveillance systems, valuables storage, power equipment management, transportation logistics, etc.
[0003] Currently, most smart safes on the market use passwords or fingerprints to unlock. Passwords are easy to be peeped and stolen, and fingerprints are easy to copy. The existing technology used in the UWB app software on Apple mobile phones has a ranging distance of only 60 meters, and it is impossible to measure distances beyond 60 meters. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a security smart box that can adopt a UWB digital key circuit. When the UWB digital key button is pressed, the UWB digital key sends an unlocking signal, and the security box connected to the UWB circuit receives the signal and opens the box lid.
[0005] In order to solve the above problems, the technical solution of the utility model is: a safe smart box with a UWB digital key unlocking circuit, including a safe box, a Bluetooth component, a data component and a positioning component are arranged in the safe box, a main board is arranged in the safe box, the Bluetooth component, the data component and the positioning component are all located on the main board, a UWB anchor point is arranged on the main board, the main board includes an MCU module, a motor drive circuit, a lithium battery, an NPC circuit, a Bluetooth circuit and a UWB circuit are electrically connected to the main board, and a motor is electrically connected to the motor drive circuit.
[0006] Furthermore, the NPC circuit, the Bluetooth circuit and the UWB circuit are all electrically connected to antennas.
[0007] Furthermore, a digital key is connected to the antenna connected to the UWB circuit.

[0010] The advantages of the utility model compared with the existing technology are:
[0011] The utility model is provided with a UWB digital key unlocking working principle: when far away from the safe box, Bluetooth is first used for identity authentication, data exchange and rough positioning. After approaching the safe box (within a dozen meters), the UWB anchor point is used for real-time ranging and positioning. After pressing the unlocking button, the digital key sends an unlocking signal, the UWB antenna of the mainboard receives the signal, the 36th foot of DW3000 outputs a data signal to the 45th foot of STM32L151VDT6, after processing by STM32L151VDT6, the 88th foot outputs a high level to the 2nd foot of MX612E, the 8th foot of MX612E outputs a high level, the 5th foot outputs a low level, the motor rotates forward, and the box cover opens.
