[0041] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0042] As mentioned in the background art, the opening and closing of electric shutters in containers currently requires a complex control system, which is not only complicated in terms of wiring but also takes up a lot of space. This is often not possible in containers with limited space.

[0043] To solve the above problems, please refer to Figure 1 and Figure 2 The present application provides a control box 100 for controlling a controlled device 200. The control box includes: a wiring module, including a second wiring terminal and a third wiring terminal; a control module, connected to the controlled device 200 through the second wiring terminal; a relay, connected to the control module, and the relay is connected to a control power supply through the third wiring terminal; wherein the relay can generate a first control signal and a second control signal according to the power-on state and the power-off state of the control power supply, respectively, and transmit the first control signal or the second control signal to the control module; when the control module receives the first control signal, it controls the controlled device 200 to open; when the control module receives the second control signal, it controls the controlled device 200 to close. Specifically, the control module can adopt a highly integrated chip module, using a compact chip to implement the control function, which can not only improve the integration of the control box 100, reduce the number of components, and make wiring simpler, but also make the control box 100 occupy less space, reduce weight, and facilitate installation, and can adapt to application scenarios with limited space. The relay generates a first control signal and a second control signal based on the power-on and power-off states of the control power supply, respectively. The control module controls the controlled device 200 based on the first and second control signals. The first control signal can be an on signal, i.e., a signal that controls the controlled device 200 to be on, and the second control signal can be a off signal, i.e., a signal that controls the controlled device 200 to be off. Optionally, the first and second control signals can be distinguished by the level of the signal; for example, a high level represents the first control signal, and a low level represents the second control signal.

[0044] In one embodiment, Figure 3 As shown, the wiring module also includes a first wiring terminal, and the control box 100 also includes: a power supply module, which is connected to the power supply through the first wiring terminal and can convert the voltage of the power supply into an operating voltage; wherein, the power supply module is also connected to the control module, and outputs the operating voltage to the control module, and the control module outputs it to the controlled device 200.

[0045] In one embodiment, the power supply voltage is an AC voltage, and the operating voltage is a DC voltage. For example, the power supply voltage may be 220V AC, and the operating voltage of the controlled device 200 may be set according to specific circumstances. For example, the controlled device 200 may be an electric blind installed on a container, and its operating voltage may be set to 24V DC. Of course, the controlled device 200 may also be other devices requiring control, and this application is not limited thereto.

[0046] Specifically, the control power supply can be provided at the client control terminal. A relay is connected to the control power supply. When the control power supply is powered on, the relay generates a first control signal and sends the first control signal to the control module, which controls the controlled device 200 to turn on. When the control power supply is powered off, the relay generates a second control signal and sends the second control signal to the control module, which controls the controlled device 200 to turn off.

[0047] The control box 100 has a simple and efficient control method. The customer can control the controlled device 200 by controlling the power on and off of the power supply. It is easy to use and easy to promote.

[0048] As an optional implementation, please refer to Figure 4 , the power module inputs the working voltage into the control module; the control module includes a positive voltage output port and a negative voltage output port; according to the first control signal, the positive voltage output port of the control module outputs a positive working voltage to the controlled device 200 to control the controlled device 200 to open; and, according to the second control signal, the negative voltage output port of the control module outputs a negative working voltage to the controlled device 200 to control the controlled device 200 to close.

[0049] Specifically, taking electric blinds as an example, when the motor of the electric blinds is connected to a positive voltage, the motor rotates forward to control the blinds to open; when the motor of the electric blinds is connected to a negative voltage, the motor rotates reversely to control the blinds to close.

[0050] The control module is connected to the power module, and the power module inputs a 24V DC voltage to the control module. The control module outputs a positive 24V voltage from the positive voltage output port according to the first control signal to control the opening of the electric blinds; or outputs a negative 24V voltage from the negative voltage output port according to the second control signal to control the closing of the electric blinds.

[0051] As an optional implementation, the control module also includes a state judgment module, which can receive a position signal emitted by the controlled device 200 to determine the position of the controlled device 200; when the control module receives the first control signal, it determines whether the controlled device 200 is fully open according to the position signal emitted by the controlled device 200, and controls the controlled device 200 to continue to open or remain in position according to the judgment result; when the control module receives the second control signal, it determines whether the controlled device 200 is fully closed according to the position signal emitted by the controlled device 200, and controls the controlled device 200 to continue to close or remain in position according to the judgment result.

[0052] For example, the state judgment module can receive a top position signal and a bottom position signal sent by the controlled device 200; if the top position signal is 1, it indicates that the controlled device 200 is fully open; if the top position signal is 0, it indicates that the controlled device 200 is in a non-fully open state; if the bottom position signal is 1, it indicates that the controlled device 200 is fully closed; if the bottom position signal is 0, it indicates that the controlled device 200 is in a non-fully closed state.

[0053] The controlled device 200 is equipped with a detector that can detect the open state and the closed state of the controlled device 200 and send the state information to the control module for storage in the state judgment module. For example, the control module is provided with an RS485 communication interface to achieve communication connection with the detector.

[0054] In one embodiment, when the control module receives the first control signal and the top position signal is 0, the positive voltage output port of the control module outputs a positive working voltage to the controlled device 200, and the motor of the controlled device 200 rotates forward;

[0055] When the control module receives the second control signal and the bottom position signal is 0, the negative voltage output port of the control module outputs a negative working voltage to the controlled device 200 , and the motor of the controlled device 200 reverses.

[0056] Specifically, Figure 5The control logic block diagram of the control box 100 in one embodiment is shown. When the control power supply is energized, the relay outputs a normally closed signal. After the control module receives the normally closed signal, its status judgment module determines whether the top position signal is normally closed. If the top position signal is normally closed, it means that the blinds are fully opened and there is no need to output an operating voltage for position adjustment. Therefore, the blinds motor stops. If the status judgment module recognizes that the top position signal is not normally closed, it means that the blinds are not fully opened and it is necessary to apply a positive operating voltage to the blinds motor to control the motor to rotate forward and open the blinds. During the process of opening the blinds, the status judgment module can receive the position signal sent by the controlled device. When it recognizes that the top position signal is normally closed, it stops outputting a positive operating voltage to the blinds motor.

[0057] When the control power supply is cut off, the relay outputs a normally open signal. After the control module receives the normally open signal, its status judgment module determines whether the bottom in place signal is normally closed. If the bottom in place signal is normally closed, it means that the blinds are completely closed and there is no need to output an operating voltage for position adjustment. Therefore, the blinds motor stops. If the status judgment module determines that the bottom in place signal is not normally closed, it means that the blinds are not completely closed and it is necessary to apply a negative operating voltage to the blinds motor to control the motor to reverse and close the blinds. During the process of closing the blinds, the status judgment module can continuously receive the position signal sent by the controlled device 200. When it is determined that the bottom in place signal is normally closed, it stops outputting a negative operating voltage to the blinds motor.

[0058] In some embodiments, the controlled device 200 is a shutter provided on a container.

[0059] For example, the control box 100 includes a shell, the wiring module, the power module and the control module are all arranged inside the shell, and the shell is installed in the container.

[0060] The control box 100 utilizes a chip as its main control element, boasting a simple structure, minimal space, and low cost. It also supports RS485 communication. Furthermore, its small number of components simplifies wiring and reduces the risk of failure. Furthermore, due to its small size and light weight, the control box 100 can be mounted using either electrical rails or screws, effectively utilizing the fragmented space within a container. It is ideally suited for applications where space is limited.

[0061] The present application further discloses a container, comprising: shutters; and the control box 100 described in any of the above embodiments, wherein the control box 100 is electrically connected to the shutters to control the shutters to be opened or closed.

[0062] The above container can realize the opening and closing control of the shutters through the above control box 100, and the control is simple and efficient.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
