[0029] See also Figure 1 and Figure 2 , Figure 1 The structure diagram of the tool cabinet in the embodiment of the present application is shown. Figure 2 A structural block diagram of a control circuit system according to an embodiment of the present application is shown.

[0030] like Figure 1 and Figure 2 As shown, according to one aspect of an embodiment of the present application, a tool cabinet is provided, comprising a tool cabinet body 1 and a control circuit system;

[0031] The tool cabinet body 1 is provided with a plurality of storage drawers 2, each of which is provided with a weight sensor and an electromagnetic lock. The weight sensor is used to measure the weight of the storage drawer 2 containing tools, and the electromagnetic lock is used to open and close the storage drawer 2.

[0032] The control circuit system includes a main control machine 3, and a weight measurement control circuit and a lock control circuit connected to the main control machine 3, the weight measurement control circuit is connected to each of the weight sensors, and the lock control circuit is connected to each of the electromagnetic locks;

[0033] The main control machine 3 is used to determine whether the user performs a tool handling operation based on the weight measurement data, and to control the opening and closing of the corresponding storage drawer 2.

[0034] The working principle of the tool cabinet of the embodiment of the present application is described below:

[0035] First, the main control unit 3 can be provided with a human-computer interaction interface, through which the user can input information about the tools to be disposed of, such as the name and quantity of the tools to be collected or returned. After obtaining the information about the tools to be disposed of, the main control unit 3 can send a weight measurement trigger signal to the weight measurement control circuit, so that the weight measurement control circuit controls the weight sensor to measure the storage drawer 2 according to the weight measurement trigger signal. Of course, the weight sensor can also actively report the weight data of the corresponding storage drawer 2 to the main control unit 3 at preset intervals, such as every 1 minute, 10 minutes, or 30 minutes, which is not limited here.

[0036] Secondly, the main control machine 3 determines the target storage drawer 2 corresponding to the tool to be disposed of based on the tool information to be disposed of input by the user, and sends a lock control trigger signal to the lock control circuit, so that the lock control circuit controls the target electromagnetic lock corresponding to the target storage drawer 2 according to the lock control trigger signal to open the target storage drawer 2, so that the user can collect or return the tool after the target storage drawer 2 is opened.

[0037] Again, the weight sensor corresponding to the target storage drawer 2 can collect the weight data of the target storage drawer 2 once before and after the user performs the tool handling operation, so that the main control machine 3 can know the change in the weight data of the target storage drawer 2 after the user performs the tool handling operation. It can be understood that if the weight data after the user's operation is less than the weight data before the operation, it means that the user has performed a tool collection operation. If the weight data after the user's operation is greater than the weight data before the operation, it means that the user has performed a tool return operation. Therefore, it is possible to determine whether the user's tool handling operation is consistent with the tool handling request input by the user in the human-computer interaction interface based on the change in weight data, and control the electromagnetic lock of the target storage drawer 2 not to close the target storage drawer 2 when inconsistent, so as to prompt the user to find an abnormal operation, thereby improving the efficiency of tool handling.

[0038] In some embodiments, the weight sensor may be a pressure sensor, and each pressure sensor may be disposed at the bottom of a corresponding storage drawer 2. The weight of the storage drawer 2 is measured by changes in the pressure signal applied to the pressure sensor and a preset correspondence between the pressure signal and the weight signal. It will be understood that the weight data collected by the weight sensor includes the weight data of the storage drawer 2 itself and the weight data of the tools placed in the storage drawer 2.

[0039] In some embodiments, the tool cabinet body 1 includes a first tool cabinet body 4 and a second tool cabinet body 5 , the first tool cabinet body 4 and the second tool cabinet body 5 are respectively provided with a plurality of the storage drawers 2 , and the main control machine 3 is set on the first tool cabinet body 4 .

[0040] It is understandable that there can be one first tool cabinet body 4 and multiple second tool cabinet bodies 5. By setting a main control machine 3 on the first tool cabinet body 4, multiple tool cabinet bodies 1 can be controlled based on one main control machine 3, effectively reducing hardware costs.

[0041] In some embodiments, in order to adapt to multiple tool cabinet bodies 1, the weight measurement control circuit includes a first weight measurement circuit board and a second weight measurement circuit board. The first weight measurement circuit board is respectively connected to the main control machine 3 and each of the weight sensors of the first tool cabinet body 4, and the second weight measurement circuit board is respectively connected to the main control machine 3 and each of the weight sensors in the second tool cabinet body 5.

[0042] In some embodiments, in order to adapt to multiple tool cabinet bodies 1, the lock control circuit includes a first lock control circuit board and a second lock control circuit board. The first lock control circuit board is respectively connected to the main control machine 3 and each of the electromagnetic locks in the first tool cabinet body 4, and the second lock control circuit board is respectively connected to the main control machine 3 and each of the electromagnetic locks in the second tool cabinet body 5.

[0043] In some embodiments, the first lock control circuit board includes a plurality of switch circuits, each of which is connected to one of the electromagnetic locks of the first tool cabinet body 4 .

[0044] like Figure 3 As shown, the first lock control circuit board includes multiple switching circuits, each switching circuit includes a power signal terminal VCC, a ground terminal GND, a first feedback signal terminal and a second feedback signal terminal. The power signal terminal VCC, the ground terminal GND, the first feedback signal terminal and the second feedback signal terminal are respectively connected to one end of the electromagnetic lock to control the closing or opening of the electromagnetic lock. The electromagnetic lock is provided with a relay, specifically to control the closing or opening of the relay.

[0045] It can be understood that the structure and principle of the second lock control circuit board are the same as those of the first lock control circuit board, and will not be described in detail here.

[0046] In some embodiments, the storage drawer 2 includes a first storage drawer 6 and multiple second storage drawers 7. The capacity of the first storage drawer 6 is greater than that of each of the second storage drawers 7. The first storage drawer 6 is provided with at least two weight sensors, and each of the second storage drawers 7 is provided with at least one weight sensor.

[0047] It can be understood that in order to meet the storage needs of tools of different sizes, at least one large-capacity first storage drawer 6 is set on each tool cabinet body 1 to meet the storage needs of large-sized tools. Since the capacity or volume of the first storage drawer 6 is large, in order to improve the accuracy of the weight measurement of the first storage drawer 6, at least two weight sensors are set in the first storage drawer 6.

[0048] In some embodiments, an information identification device is further included, and the information identification device is connected to the main control machine 3.

[0049] It is understood that information recognition devices include, but are not limited to, biometric information recognition devices and barcode scanning devices. Biometric information recognition devices may include fingerprint recognition devices, facial recognition devices, iris recognition devices, etc., and can be used to identify and record the identity of users who receive or return tools, thereby improving tool management efficiency. Barcode scanning devices may include QR code scanning devices or barcode scanning devices, etc., and users can also complete corresponding identity recognition by providing a QR code identifier, thereby improving tool management efficiency.

[0050] In some embodiments, an alarm is further included, and the alarm is connected to the main control computer 3. It is understood that the alarm can be an audible and visual alarm, which can be used to alert the user when a tool handling operation fails, for example, when the tool received by the user is inconsistent with the tool information requested.

[0051] In some embodiments, a monitoring device is further included, and the monitoring device is connected to the main control computer 3. It is understood that the monitoring device can be a camera, which can be connected to the main control computer 3 and can also be connected to a cloud server, so that back-end management personnel can monitor abnormal behavior during the use of the tool cabinet based on the monitoring video, thereby further improving the efficiency of the use of the tool cabinet.

[0052] Based on the above-disclosed content, the tool cabinet body 1 provided in the embodiment of the present application is provided with a plurality of storage drawers 2, each storage drawer 2 is provided with a weight sensor and an electromagnetic lock, the weight sensor is used to measure the weight of the storage drawer 2 containing tools, and the electromagnetic lock is used to realize the opening and closing of the storage drawer 2; the control circuit system includes a main control machine 3, and a weight measurement control circuit and a lock control circuit connected to the main control machine 3, the weight measurement control circuit is connected to each weight sensor, and the lock control circuit is connected to each electromagnetic lock; wherein, the main control machine 3 is used to determine whether the user performs a tool disposal operation based on the weight measurement data, and control the opening and closing of the corresponding storage drawer 2, for example, determining whether there is a tool in the corresponding storage drawer 2 based on the weight measurement data, thereby determining whether the user has performed an operation of returning or taking a tool, and then controlling the storage drawer 2 to open or close. Therefore, the present application improves the control efficiency of the electromagnetic lock by adding multiple weight sensors in the tool cabinet, thereby improving the use efficiency of the tool cabinet, so that it is more suitable for storing maintenance tools for large equipment such as high-speed rail or aircraft.
