The time threshold management module is used to collect the time records of using tools in a certain work position in the production position, obtain the time distribution range of the time, and use the minimum value in the time distribution range as the time judgment threshold. A human-computer interaction module is used to control the human-computer interaction interface of the smart tool cabinet, and perform human-computer interaction when employees take or return tools. When the return time of the target tool is less than the time judgment threshold, a dialog box pops up in the human-computer interaction interface to inquire whether the tool is damaged. When the employee confirms that the tool is damaged, the second storage compartment in the smart tool cabinet is opened. The human-computer interaction module includes a door lock control unit, which is used to control the door lock of the tool storage compartment in the smart tool cabinet, wherein the smart tool cabinet includes a first storage compartment and a second storage compartment, the first storage compartment is used to store tools taken and returned by employees, and the second storage compartment is used to store recycled tools.

5. The intelligent tool cabinet used in product production according to claim 4, characterized in that: The usage record management module includes: a usage record collection unit, a duration sorting unit, a duration sorting unit, and an activity evaluation coefficient calculation unit; The usage record collection unit is used to collect the usage records of tools in the intelligent tool cabinet, and set the state of binding tool information and personnel information of any tool in the target category as the access state; The time length sorting unit is used to sort the cycle periods of each tool, mark the time length of the cycle period of each tool in the cycle period arrangement sequence, and obtain the sequence number of any tool in the cycle period arrangement sequence; The activity evaluation coefficient calculation unit is used to calculate the activity evaluation coefficient of the tool.

6. The intelligent tool cabinet used in product production according to claim 4, characterized in that: The activity evaluation module includes: an activity evaluation value calculation unit, an activity evaluation value calculation unit and a target tool management unit; The activity evaluation value calculation unit is used to calculate the activity evaluation value of each tool; The activity evaluation unit is used to evaluate the activity evaluation value of the tool and obtain the low activity interval; The target tool management unit is used to select a target tool from all tools.

7. The intelligent tool cabinet used in product production according to claim 4, characterized in that: The authorization management module includes a physical tag management unit, an identity management unit and an authorization management unit; The physical tag management unit is used to manage the physical tag information. The physical tag is set on the tool. The tool corresponds to a unique physical tag. The tool information is matched with the physical tag. The physical tag includes an RFID tag, an NFC tag, a two-dimensional code and a one-dimensional barcode. The identity management unit is used to manage identity data, where the identity is used to represent the identity information of the employee, where the identity information includes the identity of the person and the position information of the employee, and the identity includes a physical identity or a biometric identity, where the physical identity includes an IC card and an NFC bracelet, and the biometric identity includes the employee's face data, iris data, fingerprint data, and voiceprint data; The authorization management unit is used to authorize employees to use tools in the smart tool cabinet. By identifying the employee's identity, the physical identification of the tool is bound to the employee's identity.

8. The intelligent tool cabinet used in product production according to claim 4, characterized in that: The first storage compartment is provided with a first electric-controlled door lock, and the second storage compartment is provided with a second electric-controlled door lock. When the first electric-controlled door lock is in an open state, the first storage compartment is in an enabled state. At this time, the second electric-controlled door lock is in a closed state and the second storage compartment is in a closed state; when the second electric-controlled door lock is in an open state, the second storage compartment is in an enabled state. At this time, the first electric-controlled door lock is in a closed state and the first storage compartment is in a closed state.
