Description

Technical Field

[0002] Wired controllers are increasingly used to control device indicator lights, further indicating the device's operating status. However, if the controller breaks down or the air conditioner loses power, the lights can become unavailable, impacting the user experience. Specifically, if the light switch was on before the power went out, the light would remain on and unable to be turned off after the controller loses power. Similarly, if the light switch was off before the power went out, the light would remain off and unable to be turned on after the controller loses power.

[0003] Currently, the wired controller integrates the light control function. The power supply of the wired controller is directly supplied through the communication line, and the power supply capacity is limited. It will only be supplied when the power supply of the indoor unit is cut off or the indoor unit cuts off the power supply of the wired controller. When the air conditioner is in standby mode, the wired controller needs to be processed for low power consumption. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the various elements and regions in the drawings are shown for schematic purposes only, and thus the present invention is not limited to the sizes or distances shown in the drawings.

[0055] To facilitate understanding of the embodiments of the present invention, specific embodiments will be further explained below with reference to the accompanying drawings. The embodiments do not limit the embodiments of the present invention.

[0056] Figure 1 This is a schematic diagram of a control circuit provided by an embodiment of the present invention. Figure 1 The control circuit specifically includes:

[0057] A first transistor T1, a second transistor T2, a relay K1, a first switch S1, a second switch S2 and an indicator light L1.

[0058] The first electrode of the first transistor T1 is connected to the first IO interface (ie, the ON button), the second electrode is connected to the first ground terminal, and the third electrode is connected to the first terminal of the relay K1.

[0059] The first electrode of the second transistor T2 is connected to the second IO interface (ie, the OFF button), the second electrode is connected to the second ground terminal, and the third electrode is connected to the second terminal of the relay K1.

[0060] The third end of the relay K1 is connected to one end of the first switch S1 and one end of the second switch S2, the fourth end of the relay K1 is connected to the other end of the first switch S1 and one end of the indicator light L1, and the fifth end of the relay K1 is connected to the power supply.

[0061] The other end of the second switch S2 is connected to the other end of the indicator light L1 .

[0062] The first electrode of the first transistor and the second transistor mentioned here is the base of the transistor, the second electrode of the first transistor and the second transistor mentioned here is the emitter of the transistor, and the third electrode of the first transistor and the second transistor mentioned here is the collector of the transistor.

[0063] The relay's internal structure includes an inductor and at least one normally-open switch. The relay's first terminal is one end of the inductor within the relay's internal structure, the relay's second terminal is the other end of the inductor within the relay's internal structure, the relay's third terminal is one end of the normally-open switch within the relay's internal structure, the relay's fourth terminal is the other end of the normally-open switch within the relay's internal structure, and the relay's fifth terminal is the end of the relay's internal structure that connects to an external power source.

[0064] During the first stage of normal operation of the control circuit, the first switch S1 remains in a normally open state, the second switch S2 remains in a normally closed state, the first IO interface (i.e., the ON button) outputs a high-level control signal to the first transistor T1, and the first transistor T1 outputs a high-level control signal to the relay K1, causing the relay K1 to close and output a drive signal to the indicator light L1, which turns on after receiving the drive signal.

[0065] During the second stage of normal operation of the control circuit, the first switch S1 remains in a normally open state, the second switch S2 remains in a normally closed state, the second IO interface (i.e., the OFF button) outputs a low-level control signal to the second transistor T2, and the second transistor T2 outputs a low-level control signal to the relay K1, so that the relay K1 is disconnected and the control indicator light L1 is turned off.

[0066] In the first stage of abnormal operation of the control circuit, after the display panel of the wire controller is removed, the control circuit automatically outputs a high-level control signal to the first switch S1. After receiving the high-level control signal, the first switch S1 remains in a normally closed state and outputs the high-level control signal to the second switch S2. After the second switch S2 outputs a high-level control signal to the indicator light L1, the indicator light L1 is turned on.

[0067] In the second stage of abnormal operation of the control circuit, after the display panel of the wire controller is removed, the control circuit automatically outputs a high-level control signal to the first switch S1. After receiving the high-level control signal, the first switch S1 remains in a normally closed state and outputs a low-level control signal to the second switch S2. After the second switch S2 outputs a low-level control signal to the indicator light L1, the indicator light L1 is turned off.

[0068] according to Figure 1 The control circuit also includes:

[0069] a first resistor R1 and a second resistor R2.

[0070] One end of the first resistor R1 is connected to the first IO interface (ie, the ON button), and the other end is connected to the first electrode of the first transistor T1.

[0071] One end of the second resistor R2 is connected to the second IO interface (ie, the OFF button), and the other end is connected to the first electrode of the second transistor T2.

[0072] The first resistor R1 and the second resistor R2 mentioned here are used to protect the circuit where the air conditioner wired controller is located.

[0073] In a possible example scenario, during the first stage of normal operation of the control circuit, the first switch S1 remains in a normally open state, and the second switch S2 remains in a normally closed state. A high-level control signal is output to the first transistor T1 through the protection of the first IO interface (i.e., the ON button) and the first resistor R1. The first transistor T1 is closed, the control relay K1 is closed, and a drive signal is output to the indicator light L1, thereby controlling the indicator light L1 to turn on.

[0074] During the second stage of normal operation of the control circuit, the first switch S1 remains in a normally open state, the second switch S2 remains in a normally closed state, and under the protection of the second IO interface (i.e., the OFF button) and the second resistor R2, a low-level control signal is output to the second transistor T2, and the second transistor T2 is disconnected, causing the relay K1 to be disconnected, thereby controlling the indicator light L1 to be turned off.

[0075] In the first stage of abnormal operation of the control circuit (power failure or line damage), after the display panel of the wire controller is removed, the control circuit automatically outputs a high-level control signal to the first switch S1, so that the first switch S remains in a normally closed state, and outputs a high-level control signal to the second switch S2, so that the second switch S2 is closed, thereby controlling the indicator light L1 to turn on.

[0076] In the second stage of abnormal operation of the control circuit, after the display panel of the wire controller is removed, the control circuit automatically outputs a high-level control signal to the first switch S1, so that the first switch S1 remains in a normally closed state, and outputs a low-level control signal to the second switch S2, so that the second switch S2 is disconnected, and a loop cannot be formed, thereby controlling the indicator light L1 to turn off.

[0077] The control circuit provided in the embodiment of the present invention is provided with a first transistor, a second transistor, a relay, a first switch, a second switch and an indicator light; by integrating the first switch and the second switch on the online controller, when the online controller is operating normally, the state of the indicator light is controlled by the relay; when the online controller is powered off, the state of the indicator light is controlled by controlling the first switch and the second switch. By integrating the light switch function into the online controller, the online controller is installed in the light switch position without having to drill a hole and reinstall the online controller. This solution can achieve diversified functions of the online controller, and solve the technical effect of the problem that the lighting cannot be used after the air conditioner is damaged or the online controller is powered off, which affects the user experience.

[0078] Figure 2 A flow chart of a control method provided in an embodiment of the present invention. Applied to the control circuit of the previous embodiment. Figure 2 The control method specifically includes:

[0079] S201: Acquire the switch state of the first transistor and the switch state of the second transistor.

[0080] The embodiment of the present invention is implemented by a wired controller. By integrating a first switch and a second switch, when the wired controller is operating normally, the on / off state of the first transistor and the second transistor is controlled to control the on / off state of the relay, and the on / off state of the relay controls the state of the indicator light. When the wired controller experiences a power outage, the relay fails, the control circuit automatically controls the first switch to a normally closed state, and the on / off state of the second switch controls the state of the indicator light. By integrating a light switch function, the wired controller can be directly installed in the light switch position without having to drill a hole to reinstall the wired controller, thereby achieving diversified functions of the wired controller and resolving the problem of the lighting being unusable after an air conditioner is damaged or the wired controller is powered off, which affects the user experience.

[0081] Furthermore, the current states of the first transistor and the second transistor are collected by the system to prepare for determining the state of the relay.

[0082] S202 : Control driving states of relays respectively connected to the first transistor and the second transistor according to the switching state of the first transistor and the switching state of the second transistor.

[0083] The driving state mentioned here can be understood as the driving state when the relay is turned on and the disconnecting state when the relay is turned off.

[0084] Furthermore, according to the switching state of the first transistor and the switching state of the second transistor, when the first transistor is closed and the second transistor is disconnected, the control relay is turned on and is in the driving state; when the first transistor is disconnected and the second transistor is closed, the control relay is turned off and is in the disconnected state.

[0085] S203: Determine the working mode of the wired controller.

[0086] The working mode mentioned here can be understood as normal working mode or abnormal working mode.

[0087] Furthermore, the operating mode of the wired controller can be determined based on the driving state of the relay. When the relay is in the driving state, the wired controller is in the normal operating mode; when the relay is in the disconnected state, the wired controller is determined to be in the abnormal operating mode.

[0088] S204: Control the indicator lights in the control circuit according to the working mode.

[0089] Furthermore, by determining the working mode of the wire controller, the working state of the current line and the state of the relay are represented, and then the control strategy of the indicator light is determined, and then the indicator light is controlled.

[0090] A control method provided by an embodiment of the present invention determines the driving state of a relay by obtaining the switching state of a first transistor and a second transistor; determines the working mode of the circuit in which the wire controller is located according to the driving state of the relay, and adopts different control strategies according to different working modes to control the indicator lights, thereby realizing the diversification of the functions of the wire controller and solving the technical effect of the problem that the lighting cannot be used after the air conditioner is damaged or the wire controller is out of power, which affects the user experience.

[0091] Figure 3 A flowchart of another control method provided by an embodiment of the present invention. Figure 3 This is introduced based on the second embodiment. Figure 3 The control method further includes:

[0092] S301: Acquire the switch state of the first transistor and the switch state of the second transistor.

[0093] The embodiment of the present invention is implemented by a wired controller. By integrating a first switch and a second switch, when the wired controller is operating normally, the on / off states of the first and second transistors are controlled to control the on / off states of the relay, which in turn controls the state of the indicator light. When the wired controller experiences a power outage, the relay fails, the control circuit automatically controls the first switch to a normally closed state, and the on / off state of the second switch controls the state of the indicator light. This achieves diversified wired controller functionality and resolves the issue of the lighting failing after an air conditioner is damaged or the wired controller loses power, impacting user experience.

[0094] Furthermore, the current states of the first transistor and the second transistor are collected by the system to prepare for determining the state of the relay.

[0095] S302: When the first transistor is in the on state and the second transistor is in the off state, the control relay is in the start state.

[0096] S303: When the first transistor is in the off state and the second transistor is in the on state, the control relay is in the off state.

[0097] Furthermore, according to the switching state of the first transistor and the switching state of the second transistor, when the first transistor is closed and the second transistor is disconnected, the control relay is turned on and is in the driving state; when the first transistor is disconnected and the second transistor is closed, the control relay is turned off and is in the disconnected state.

[0098] S304: Determine whether the wired controller is in a power-off state.

[0099] S305: When the wired controller is in the power-off state, determine that the wired controller is in the power-off mode.

[0100] S306: When the wired controller is not in the power-off state, determine that the wired controller is in the working mode.

[0101] Furthermore, the operating mode of the wired controller can be determined based on the driving state of the relay. When the relay is in the driving state, the wired controller is determined to be in a normal operating state, and thus in the operating mode; when the relay is in the disconnected state, the wired controller is determined to be in an abnormal power-off state, and thus in the power-off mode.

[0102] S307 : When the wired controller is in the power-off mode, control the first switch to be in a normally closed state.

[0103] S308: When the second switch is in the off state, the indicator light is controlled to turn on.

[0104] S309: When the second switch is in the off state, the indicator light is controlled to be turned off.

[0105] Furthermore, when the wired controller is in an abnormal power-off mode, by unplugging the display screen of the wired controller, the first switch automatically closes regardless of whether the relay was in an on or off state before the abnormality, and remains in a normally closed state, and the opening and closing of the indicator light is controlled by the opening and closing of the second switch.

[0106] S310: When the wired controller is in the working mode, the first switch is controlled to be in a normally open state by a manual button, and the second switch is controlled to be in a normally closed state by a manual button.

[0107] S311. When the relay is in the starting state, the indicator light is turned on.

[0108] S312. When the relay is in the disconnected state, the indicator light is turned off.

[0109] Furthermore, when the wired controller is in normal working mode, the display screen of the wired controller is buckled together with the control circuit. At this time, the first switch is structurally set to be in the open state and the second switch is in the closed state. The control circuit can control the state of the indicator light through the open and closed state of the relay.

[0110] Another control method provided by an embodiment of the present invention determines the driving state of the relay by obtaining the switching state of the first transistor and the second transistor; determines the working mode of the circuit where the wire controller is located according to the driving state of the relay, and adopts different control strategies according to different working modes to control the indicator light, thereby realizing the diversification of the functions of the wire controller and solving the technical effect of the lighting being unusable after the air conditioner is damaged or the wire controller is out of power, which affects the user experience.
