Description

Technical Field

[0001] This application relates to the field of power supply technology, and in particular to a device control circuit and apparatus. Background Technology

[0002] In related technologies, equipment control circuits typically include a normally closed wall control switch, a power supply circuit, and an alternating current (AC) signal detection circuit. When a user presses the wall control switch, it switches from a closed to an open state; when the user releases the wall control switch, it switches back to a closed state. The AC detection circuit is mainly used to detect the open state of the wall control switch and switch the state of the controlled equipment accordingly. Taking a lighting fixture as an example, when the wall control switch is detected to be pressed, the operating state of the lighting fixture is controlled, such as turning the light on or off, or switching to other operating modes.

[0003] The above control methods effectively meet the user's need for remote control, but the controlled device is in a long standby state, that is, a long-term power consumption state, which not only wastes electricity and does not meet national environmental protection requirements, but also causes financial losses to the user.

[0037] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0039] In some embodiments, such as Figure 1-3As shown in any figure, the control circuit of the device includes: a first switch module 1, a second switch module 2, and a main control module 3; the input terminal a of the first switch module 1 is electrically connected to the power supply 4, the first output b of the first switch module 1 is electrically connected to the first input terminal d of the second switch module 2, the second output terminal c of the first switch module 1 is electrically connected to the second input terminal e of the second switch module 2, the output terminal f of the second switch module 2 is electrically connected to the main control module 3, and the output terminal of the main control module 3 is electrically connected to the control terminal of the second switch module 2.

[0040] The first switch module 1 has two states: a first state and a second state. The first state includes a closed first output terminal b and an open second output terminal c (i.e., ab closed and ac open), and the second state includes a closed first output terminal b and a closed second output terminal c (i.e., ab open and ac closed). The second switch module 2 has two states: a third state and a fourth state. The third state includes an open first input terminal d and a closed second input terminal e (i.e., df open and ef closed), and the fourth state includes a closed first input terminal d and an open second input terminal e (i.e., df closed and ef open). The first switch module 1 is configured to switch from the first state to the second state in response to a user's pressing operation. The second switch module 2 is configured to switch from the third state to the fourth state in response to a first control signal sent by the main control module 3. The first switch module 1 is also configured to switch from the second state to the first state in response to a user's releasing operation.

[0041] like Figure 1 As shown, the initial state of the device control circuit is a de-energized state. At this time, the first switch module 1 is in the first state, that is, ab is closed and ac is open; the second switch module 2 is in the third state, that is, df is open and ef is closed. The main control module 3 cannot be connected to the power supply 4. The device control circuit is completely de-energized and does not generate standby power consumption.

[0042] like Figure 2 As shown, when the user presses the first switch module 1, the first switch module 1 switches from the first state to the second state, that is, from ab closed and ac open to ab open and ac closed. At this time, the second switch module 2 is still in the third state, that is, df open and ef closed. The main control module 3 connects to the power supply 4 through the acef path. After the main control module 3 is powered on, it sends the first control signal to the second switch module 2. Figure 3As shown, in response to the received first control signal, the second switch module 2 switches from the third state to the fourth state, i.e., from df open and ef closed to df closed and ef open. Simultaneously, the user releases the first switch module 1, which switches back from the second state to the first state, from ab open and ac closed to ab closed and ac open. The main control module 3 connects to the power supply 4 through the abdf circuit, and the device control circuit enters standby mode. When the user needs to control the operating state of the device, they can control the device by pressing the first switch module 1 and the AC detection circuit. The control logic at this time is the same as that in related technologies and will not be described further here.

[0043] When the user needs to completely shut off the power, the main control module 3 can send a second control signal to the second switch module 2. In response to the received second control signal, the second switch module 2 switches from the fourth state to the third state, i.e., from DF closed and EF open to DF open and EF closed. At this time, the first switch module 1 is in the first state, i.e., AB closed and AC open. The device control circuit is completely powered off, returning to normal operation. Figure 1 The state shown is without power, and no more standby power consumption is generated.

[0044] The device control circuit provided in this application embodiment is suitable for electrical equipment that is not used for a long time, or for situations where the user is away for a long time (such as on a business trip). It switches the device control circuit to a non-powered state, completely disconnects the power to the electrical equipment, and improves safety.

[0045] The device control circuit provided in this application embodiment switches from a non-powered state to a standby state by pressing the first switch module 1, and also switches from the standby state back to a non-powered state by sending a second control signal to the second switch module 2 through the control main control module 3. This achieves complete power-off of the device control circuit, eliminating standby power consumption, solving the standby power consumption problem, thereby reducing money waste, saving resources, being more environmentally friendly, and increasing safety in use.

[0046] It should be noted that the embodiments of this application do not limit the type of AC detection circuit, including all circuits that meet the requirements for AC signal detection. The embodiments of this application do not limit the type of the device to be controlled, including all types of electrical equipment known to those skilled in the art, such as lighting fixtures.

[0047] In some embodiments, such as Figure 4 As shown, the second switch module 2 includes a relay 21, and the control terminal of the relay 21 is electrically connected to the output terminal of the main control module 3.

[0048] In this embodiment, it is assumed that the initial state of the device control circuit is a non-energized state. The first switch module 1 is in the first state, that is, ab is closed and ac is open. The relay 21 is not working and is in the third state, that is, df is open and ef is closed. At this time, the device to be controlled is in a non-energized state. When the user needs to control the device, pressing the first switch module 1 switches it from AB closed and AC open to AB open and AC closed. At this time, the EF of relay 21 closes, and the main control module 3 connects to power 4 through the ACEF circuit. The main control module 3 then sends a first control signal (e.g., a high-level signal) to relay 21, causing relay 21 to switch from DF open and EF closed to DF closed and EF open. Simultaneously, releasing the first switch module 1 returns it from AC closed to AB closed, placing it in the first state (AB closed and AC open). Relay 21 is in the DF closed and EF open state, and the main control module 3 connects to power 4 through the ABDF circuit. The device control circuit then enters standby mode. In standby mode, the main control module 3 continuously sends the first control signal to relay 21. When the user needs to completely turn off the power, the main control module 3 sends a second control signal (e.g., a low-level signal) to the relay 21. The relay 21 stops working and switches from df closed and ef open to df open and ef closed. At this time, the first switch module 1 is in the first state (i.e., ab closed and ac open). The entire device control circuit is completely de-energized and in a non-energized state, and no longer generates standby power consumption.

[0049] In other embodiments, the relay may be replaced with other electronic devices with gating functions, such as a single-pole double-throw switch, which is not limited here.

[0050] In some embodiments, such as Figure 5 As shown, the second switch module also includes a switch device 22. The control terminal of the switch device 22 is electrically connected to the output terminal of the main control module 3. The first terminal of the switch device 22 is electrically connected to the control terminal of the relay 21. The second terminal of the switch device 22 is grounded.

[0051] In this embodiment, in response to the first control signal sent by the main control module 3, the switching device 22 is in the on state, and the relay 21 is activated, switching from df open and ef closed to df closed and ef open. In response to the second control signal sent by the main control module 3, the switching device 22 is in the off state, and the relay 21 is not activated, switching from df closed and ef open to df open and ef closed.

[0052] In some embodiments, the switching device includes a transistor or a metal-oxide-semiconductor (MOS) field-effect transistor.

[0053] For example, such as Figure 5 As shown, the switching device 22 includes an NPN transistor. The base of the NPN transistor is connected to the output terminal of the main control module 3, the collector is electrically connected to the control terminal of the relay 21, and the emitter is grounded.

[0054] For example, such as Figure 9 As shown, the base of the NPN transistor is electrically connected to the IO0 port of the main control module 3 (or the main control and communication chip 31). When the first control signal is high, the NPN transistor is in the conducting state, and relay 21 operates, switching from df open and ef closed to df closed and ef open. When the second control signal is low, the NPN transistor is in the off state, relay 21 does not operate, and switching from df closed and ef open to df open and ef closed.

[0055] It should be noted that, Figure 5 or Figure 9 The example shown only illustrates that the switching device 22 includes an NPN transistor, and does not constitute a limitation on the identification control circuit provided in the embodiments of this application. In other embodiments, the switching device 22 may also include a PNP transistor, which is not limited herein. Similarly, the switching device 22 may also include an NPN MOSFET or a PNP MOSFET.

[0056] In some embodiments, such as Figure 6 As shown, the second switch module 2 also includes a diode 23, which is connected in parallel with the relay 21.

[0057] For example, such as Figure 6 As shown, the anode of diode 23 is connected to the collector of the transistor, and the cathode of diode 23 is connected to the +12V power supply.

[0058] In some embodiments, such as Figure 7 As shown, the device control circuit also includes: a fuse 5; the fuse 5 is located in the circuit between the first output terminal b and the first input terminal d, and the fuse 5 is located in the circuit between the second output terminal c and the second input terminal e.

[0059] In some embodiments, the fuse 5 is located on the circuit between the first output terminal b and the first input terminal d.

[0060] In some embodiments, the fuse 5 is located on the circuit between the second output terminal c and the second input terminal e.

[0061] This configuration, by placing a fuse in the path between the first switch module 1 and the second switch module 2, further ensures user safety.

[0062] In some embodiments, such as Figure 8 As shown, the main control module 3 includes: a main control and communication chip 31.

[0063] In this embodiment, the main control chip and communication chip are integrated, and the main control and communication chip 31 simultaneously possesses communication and control functions. With this configuration, the user can remotely control the device under control to switch operating modes and control the main control and communication chip 31 to send a second control signal to the second switch module, causing the device's control circuit to be completely powered off, via a terminal device that is communicatively connected to the main control and communication chip 31. Exemplarily, the main control and communication chip 31 connects to the terminal device via a wireless network (WIFI) or Bluetooth.

[0064] In some embodiments, such as Figure 9 As shown, the control circuit of the device also includes: a filter module 6, an AC / DC conversion module 7, and a voltage regulator module; the input terminal of the filter module 6 is electrically connected to the output terminal f of the second switch module, the output terminal of the filter module 6 is electrically connected to the input terminal of the AC / DC conversion module 7, the output terminal of the AC / DC conversion module 7 is electrically connected to the input terminal of the voltage regulator module, and the output terminal of the voltage regulator module is electrically connected to the input terminal of the main control module 3.

[0065] In this embodiment, the filtering module 6 includes, but is not limited to, capacitor filtering circuits, inductor filtering circuits, resistor-capacitor (RC) filtering circuits, inductor-capacitor (LC) filtering circuits, and resistor-capacitor-inductor (RCL) filtering circuits, and also includes all filtering circuits known to those skilled in the art, which are not limited herein. For example, as... Figure 9 As shown, filter module 6 is a resistor-capacitor-inductor (RCL) filter circuit, including filter inductor L1, filter capacitor CX1 and filter resistor VR1.

[0066] The AC / DC converter module 7 is used to convert AC power to DC power. For example, the AC / DC converter module 7 converts 220V AC power to 12V DC power.

[0067] The voltage regulator module converts the DC output from the AC / DC converter module 7 into DC power that meets the operational requirements of the main control module 3 (or the main control and communication chip 31). For example, the voltage regulator module converts 12V DC to 3.3V DC to meet the power supply requirements of the main control module 3 (or the main control and communication chip 31). The voltage regulator module includes, but is not limited to, low dropout regulators (LDOs) and DC-DC converters.

[0068] In some embodiments, such as Figure 9 As shown, the output of AC / DC conversion module 7 is electrically connected to the device to be controlled 8; the main control module 3 is communicatively connected to the device to be controlled 8.

[0069] In this embodiment, the AC / DC conversion module 7 provides converted DC power to the device 8 to be controlled. The main control module 3 (or the main control and communication chip 31) sends control signals to the device 8 to be controlled.

[0070] In some embodiments, such as Figure 9 As shown, the control circuit of the device also includes an AC detection module. The input terminal (i.e., L3) of the AC detection module is electrically connected to the first output terminal b of the first switch module 1, and the detection terminal (i.e., AC-50 detection) is electrically connected to the main control module 3 (or the main control and communication chip 31).

[0071] Based on the above embodiments, this application also provides a device control apparatus, which includes any of the above-described device control circuits, having the same beneficial effects. To avoid repetition, it will not be limited here.

[0072] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0073] The above are merely specific embodiments of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
