[0001] This utility model relates to the field of inductors, and more specifically, to an intelligent inductor. Background Technology

[0002] Inductors, as a basic electrical component, are frequently used in teaching and experiments. In school laboratories, when conducting experiments on inductors and circuits, students often need to replace the inductors in the circuit with components of different values. For example, they need to observe the situation of inductors with values ​​of 100mH, 1H, and 10H in the circuit. Each experiment may require multiple groups of students, and each student needs to disassemble and rewire the inductor for each value, which is inconvenient and wastes time. Utility Model Content

[0003] The problem solved by this invention is how to provide an intelligent inductor that can intelligently switch the required inductance value and is easy to use.

[0004] To address the aforementioned problems, this utility model provides an intelligent inductor, comprising: a housing, a control panel and wiring terminals disposed on the surface of the housing, and an inductor module, a relay module, and a control module disposed within the housing. The wiring terminals include a first terminal and a second terminal. The relay module includes multiple branch relays. The inductor module includes multiple inductors with preset values ​​of different values. The first ends of the multiple inductors are interconnected and connected to the first terminal. The second end of each inductor is connected to the second terminal after passing through the opening of a corresponding branch relay. The control module includes a main control circuit and a drive circuit. The control panel is connected to the main control circuit. The output terminal of the main control circuit is connected to multiple drive circuits.

[0005] Furthermore, the control module also includes a power supply circuit, which provides power to the control panel, main control circuit, and drive circuit.

[0006] Furthermore, the control panel is a touch display panel.

[0007] Furthermore, the driving circuit includes a first transistor and a first diode. The base of the first transistor is connected to the output terminal of the main control circuit, the emitter is grounded, and the collector is connected to the power supply via the corresponding branch relay.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Before use, the laboratory management personnel can change the inductors inside the box according to the needs. When conducting experiments, users only need to select and switch the inductors on the control panel to connect them to the experimental circuit.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0019] like Figure 1 As shown, this utility model provides an intelligent inductor, comprising: a housing, a control panel and wiring terminals disposed on the surface of the housing, and an inductor module, a relay module, and a control module disposed within the housing. The wiring terminals include a first terminal and a second terminal. The relay module includes multiple branch relays. The inductor module includes multiple inductors with preset values ​​of different values. The first ends of the multiple inductors are interconnected and connected to the first terminal. The second end of each inductor is connected to the second terminal after passing through the opening of a corresponding branch relay. The control module includes a main control circuit and a drive circuit. The control panel is connected to the main control circuit. The output terminal of the main control circuit is connected to multiple drive circuits. The coil of each branch relay is connected to the output terminal of a corresponding drive circuit, so that the main control circuit controls the on / off state of each branch relay.

[0020] It should be noted that, as Figure 1 and Figure 2 As shown in the diagram, only four sets of inductors with different values ​​are connected. The other sets of inductors operate on the same principle. Before use, the experiment administrators can change the inductors in the box according to their needs. When conducting experiments, users only need to select and switch the inductors on the control panel to connect them to the experimental circuit. The control module controls the relay module to activate, connecting the branch relay connected to the selected inductor. The inductor then obtains the corresponding inductance value. Users can connect inductors of different values ​​simply through the control panel without disassembling or rewiring, making it convenient for multiple groups of students to use in turn and saving time.

[0021] In one embodiment of this utility model, the control module further includes a power supply circuit, which provides power to the control panel, the main control circuit, and the drive circuit.

[0022] It should be noted that the power supply circuit can be powered externally, and after rectification and voltage conversion, it provides the required DC power to the main control circuit and drive circuit.

[0023] In one embodiment of this utility model, the control panel is a touch display panel.

[0024] It should be noted that the touch display panel communicates with the main control circuit. Through the touch display panel, users can view the currently connected inductors and select the inductor to switch via touch operation.

[0025] In one embodiment of this utility model, such as Figure 3 As shown, the driving circuit includes a first transistor and a first diode. The base of the first transistor is connected to the output terminal of the main control circuit, the emitter is grounded, and the collector is connected to the power supply via the corresponding branch relay. The cathode of the first diode is connected to the base of the first transistor, and the anode is connected to the emitter of the first transistor.

[0026] It should be noted that when the main control circuit receives the signal for the inductor to be connected, it sends a drive signal to the drive circuit corresponding to the branch relay connected to that inductor, so as to... Figure 3 Taking the first drive circuit as an example, the first transistor Q1 is turned on under the drive signal, which energizes the two ends of the corresponding branch relay K1 and closes its opening. The two ends of the selected inductor L1 are connected to the first terminal and the second terminal respectively, and connected to the experimental circuit.

[0027] In one embodiment of this utility model, the relay module further includes a main circuit relay, the coil of which is connected to the output terminal of one of the drive circuits, and the opening of the main circuit relay is disposed between the first terminal and the inductor module.

[0028] It should be noted that, as Figure 1 As shown, the main relay is used to control the connection between the first terminal and the first terminal of each inductor. Since the relay contacts are used, after the user finishes using the device, closes the panel, or experiences a sudden power failure, the contacts of both the main and branch relays are in the open state, and the two terminals are not connected to the inductors. This prevents the inductors from discharging to the terminals after using stored energy.

[0029] In one embodiment of this utility model, the control module further includes a storage circuit, which is connected to the main control circuit and is used to store the numerical information of the inductor.

[0030] It should be noted that administrators can input and store the values ​​of each inductor in the box via the panel, making it convenient for users to view the inductor values ​​and select / switch them.

[0031] In one embodiment of this utility model, the control module further includes a temperature acquisition circuit, which is connected to the main control circuit to transmit the acquired temperature information inside the enclosure to the main control circuit.

[0032] It should be noted that the temperature acquisition circuit can continuously monitor the temperature inside the enclosure and obtain information on the inductor's heating status.

[0033] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
