[0028] Such as Figure 1As shown in the figure, the present application provides a switch linkage system, including a main control unit, a first switch unit K1, a second switch unit K2, and a power storage unit. The first switch unit K1 is located in the mains circuit where the main control unit, the lighting circuit, and the host of the drying machine are located at the same time, and is used to control the connection of the main control unit, the lighting circuit, and the host of the drying machine to the mains. The second switch unit K2 is connected to the main control unit and is used to send a switch signal to the main control unit. The main control unit is connected to the lighting circuit and is used to control the connection state of the lighting circuit to the mains. The main control unit is connected to the host of the drying machine and is used to send a drying machine lifting instruction to the host of the drying machine according to the received switch signal. The power storage unit is arranged in the host of the drying machine to supply power to the host of the drying machine, and is charged through the mains connected to the host of the drying machine.

[0029] The present application mainly solves the problem that when a house is delivered, a balcony lamp has been installed on the balcony. In order not to waste in the future, a drying machine without lighting is directly installed on this basis. The wall switch is used to directly control the balcony lamp and the drying machine, and the linkage between the lighting circuit and the drying machine is realized, etc.

[0030] The main control unit includes a core controller and peripheral circuits. The peripheral circuits include a step-down rectifier circuit. The input end of the step-down rectifier circuit is connected to the output end of the first switch unit K1, and the output end of the step-down rectifier module supplies power to the control module of the main control unit. The mains passes through the first switch unit K1 and is step-down rectified by the step-down rectifier circuit before being supplied to the controller and other devices in the main control unit for power supply.

[0031] In one embodiment, both the first switch unit K1 and the second switch unit K2 are arranged in a wall switch box.

[0032] Among them, as Figure 2 shown, both the first switch unit K1 and the second switch unit K2 can be arranged in an 86 box. The controller in the main control unit can be an MCU. The first switch unit K1 can be a single-throw switch. When the first switch unit K1 is in the on state, that is, the mains are respectively connected to the main control unit, the lighting circuit, and the host of the drying machine. When the first switch unit K1 is in the off state, that is, the mains are respectively disconnected from the main control unit, the lighting circuit, and the host of the drying machine. The second switch unit K2 can be a micro control switch. One end of the second switch unit K2 is connected to the main control unit, and the other end is connected to GND or VCC. In the figure, GND is taken as an example. When the second switch unit K2 is closed, a closed signal is provided for the main control unit. When the second switch unit K2 is opened, an open signal is provided for the main control unit. In one case, when the second switch unit K2 is closed, the closed signal corresponds to a drying machine rising instruction. In another case, when the second switch unit K2 is closed, the closed signal corresponds to a drying machine falling instruction. The power storage unit is arranged in the host of the drying machine. The power storage unit includes a charge and discharge management module and a storage battery plate. The charge and discharge management module is used to control the charge and discharge of the storage battery plate.

[0033] In one embodiment, the main control unit is connected to the lighting circuit through a switching device. The control end of the switching device is connected to the main control unit, and the controlled end of the switching device is arranged in the mains circuit where the lighting circuit is located. The main controller controls the connection between the lighting circuit and the mains by controlling the working state of the switching device.

[0034] Among them, the switching device is a relay. In the figure, the control end marked as the switching device is the coil K3, and the controlled end of the switching device is the normally open switch K3. The coil K3 is connected to the main control unit, receives the control of the main control unit, and then controls the normally open switch K3, thereby controlling the connection and disconnection between the lighting circuit and the mains.

[0035] In one embodiment, it further includes a light intensity detection unit; the light intensity detection unit is connected to the main control unit, and is used to detect the light intensity information and send the detected light intensity information to the main control unit, so that the main control unit controls the working state of the switching device according to the light intensity information.

[0036] This is to avoid wasting resources and mis-turning on the lighting. When the light intensity is strong, that is, when the brightness is high, such as during the day, the first switch unit K1 is in the conducting state, and the lighting circuit is disconnected from the mains; when the light intensity is weak, that is, when the brightness is low, such as at night, the first switch unit K1 is in the conducting state, and the lighting circuit is connected to the mains.

[0037] Such as Figure 3 As shown, in one embodiment, the light intensity detection unit is a photodiode. The anode of the photodiode is connected to the DC power input terminal, and the cathode of the photodiode is connected to the main control unit through a resistor; when the first voltage output by the photodiode is greater than or equal to the first preset voltage, the main control unit controls the connection between the lighting circuit and the mains through the switching device; when the first voltage output by the photodiode is less than the first preset voltage, the main control unit controls the disconnection between the lighting circuit and the mains through the switching device.

[0038] A photodiode is an optoelectronic device based on the photoelectric effect. When light irradiates its PN junction, a photocurrent will be generated, and its magnitude is proportional to the light intensity. The output current changes, and it has a fast response speed and high sensitivity. A photodiode is usually used as a converter from optical signal to electrical signal, and controls the switch or brightness of the lamp by detecting the light intensity. The light intensity detection unit can also be a photoresistor. A photoresistor, also known as a photoconductor, has a resistance value that changes with the change of light intensity, and has a simple structure and low cost. When the light intensity increases, the resistance value of the photoresistor decreases; conversely, when the light intensity decreases, the resistance value increases. Moreover, a photoresistor is usually used as a photosensitive element, and changes the current or voltage in the circuit by detecting the change of light intensity, thereby controlling the working state of the lamp.

[0039] For the purpose of energy conservation, the lighting circuit can also adjust the power or / and color temperature according to the light intensity. The power adjustment circuit includes an amplifier, a resistor, and a diode. In one embodiment, the positive input terminal of an amplifier is connected to the signal input terminal of the power adjustment circuit; the negative input terminal of the amplifier, one end of a resistor, and one end of another resistor are connected; the output terminal of the amplifier, the other end of a resistor, the signal output terminal of the power adjustment circuit, and the positive electrode of the diode are connected to the positive input terminal of another amplifier; the negative input terminal of another amplifier is connected to one end of a third resistor; the output terminal of another amplifier and the other end of the third resistor are connected to the negative electrode of the diode; the positive power input terminals of one amplifier and another amplifier are connected to the power input terminal of the power adjustment circuit; the negative power input terminals of one amplifier and another amplifier and the other end of another resistor are grounded. In one embodiment, the color temperature adjustment circuit includes a triode, a resistor, and a MOS transistor; the signal input terminal of the color temperature adjustment circuit, the base of the triode, and one end of the resistor are connected; the other end of the resistor, the collector of the triode, and the source of the MOS transistor are connected; the collector of the triode, one end of a fifth resistor, and the power input terminal are connected; the emitter of the triode is connected to the gate of the MOS transistor; the drain of the MOS transistor is connected to the output terminal, and there is more than one output terminal.

[0040] There can also be PWM signal adjustment. The duty cycle of the PWM signal increases and decreases in a cycle, that is, the duty cycle of the PWM signal increases from the current duty cycle to the maximum preset duty cycle according to a preset ratio, and then decreases from the maximum preset duty cycle to the minimum preset duty cycle according to a preset ratio, and then increases to the maximum preset duty cycle again, and so on in a cycle until a confirmation signal is received. The minimum preset ratio is greater than or equal to 0%, and the maximum preset duty cycle is generally 100%. Among them, the preset ratio can be set to 2%, and the adjustment interval of the preset ratio can be set to 0.1S. Or, the duty cycle of the PWM signal can decrease from the current duty cycle to the minimum preset duty cycle according to a preset ratio, and then increase from the minimum preset duty cycle to the maximum preset duty cycle according to a preset ratio, and then decrease to the minimum preset duty cycle again, and so on in a cycle until a confirmation signal is received. Before adjusting the cyclic increase and decrease of the PWM signal, the difference between the maximum preset duty cycle and the current duty cycle can be compared with the preset ratio. When the difference between the maximum preset duty cycle and the current duty cycle is less than the preset ratio, the PWM signal is directly output as the maximum preset duty cycle. In this way, the need for custom lighting can be met, and the atmosphere can be created by adjusting the light power and color temperature.

[0041] In one embodiment, the main control unit is connected to the main controller in the host of the clothes dryer through the first wireless communication module.

[0042] The main controller in the host of the clothes dryer is also provided with a wireless communication module, or is connected to a wireless communication module. The main control unit is connected to the main controller in the host of the clothes dryer, that is, wirelessly connected to the wireless communication module through the first wireless communication module.

[0043] In one embodiment, the main control unit further includes a second wireless communication module. The second wireless communication module is connected to a terminal to query the status of the lighting circuit and the host of the clothes dryer in real time, and receive fault information.

[0044] The first wireless communication module and the second wireless communication module can be provided in the main control unit, or can be independent of the main control unit to form a separate module. In the figure, the wireless chip of the first wireless communication module is 433MHz wireless, and is connected to the main control unit through a capacitor C, a resistor R2, and a resistor R3. Alternatively, the wireless can be Bluetooth, and both have different advantages. Bluetooth has the advantages of low power consumption and short-distance communication, can establish a stable connection within a relatively short distance, achieve fast response and efficient control; Bluetooth can easily be compatible with a variety of devices to achieve seamless connection and control; and can be paired and controlled with multiple Bluetooth devices at the same time; certain encryption measures are adopted to make data transmission more secure and reliable. 433MHz wireless can effectively control controlled devices at a relatively long distance, and is suitable for control requirements outdoors or in large spaces. It is less affected by interference; has strong penetration ability and can penetrate some obstacles for communication; since the 433MHz frequency band belongs to a free frequency band and the technology is mature, it may have more cost advantages. Therefore, when using Bluetooth or 433MHz wireless for control, there are obvious differences in terms of communication distance, device compatibility, anti-interference ability, penetration ability, and cost. It is necessary to select a suitable module according to specific application scenarios and requirements. For this application, both are applicable. The second wireless communication module can be selected as WiFi.

[0045] In one embodiment, the power supply end of the power storage unit is respectively connected to the main controller and the drying rod power system in the host of the clothes dryer, and is used to supply power to the main controller and the drying rod power system when the host of the clothes dryer disconnects from the mains, so that the main controller controls the drying rod to rise through the drying rod power system when the host of the clothes dryer disconnects from the mains.

[0046] In one embodiment, the main controller is provided with a zero-crossing detection circuit. The main controller is used to control the working state of the power storage unit according to the detection signal output by the zero-crossing detection circuit, so as to control charging or supply power to the main controller and the drying rod power system.

[0047] The power supply terminal in the energy storage unit is arranged in the energy storage board. The main controller in the host of the clothes dryer can detect the state of the first switch unit K1 from the on-state to the off-state through the zero-crossing circuit, and control the energy storage unit to supply power to the main controller and the drying rod power system in the host of the clothes dryer. The energy storage unit can also include a solar panel to convert solar energy into electrical energy. In addition, the charging and discharging strategies can be adjusted to ensure the maximum utilization of electrical energy. For example, on sunny days, the electrical energy converted from the sun is preferentially stored in the energy storage board. On rainy or cloudy days or at night, it will automatically switch to mains charging to ensure that the energy storage board is in a state of sufficient electrical energy, thus ensuring the normal operation of the clothes dryer. The energy storage unit also has overcharge, over-discharge and short-circuit protection functions to ensure the safe and stable operation of the system. In case of emergency, the energy storage unit can also be used as an emergency power supply to provide temporary power support.

[0048] To further improve energy efficiency, the energy storage unit is also combined with other functional modules of the clothes dryer. For example, when the clothes dryer is in the standby state, the main control board will automatically reduce energy consumption, and at the same time the energy storage unit will also correspondingly reduce the charging power to extend the service life of the energy storage board. In short, through the design of the energy storage unit, the clothes dryer can not only achieve energy conservation and environmental protection, but also get rid of the dependence on the traditional power grid to a certain extent, bringing a more intelligent and convenient living experience to users.

[0049] In addition, the light intensity detection unit can also be linked with the driving device of the curtain. When strong light is detected, the driving device of the curtain is automatically started to protect indoor furniture and decorations from direct sunlight damage. For more precise control, the balcony can be divided into sub-areas to obtain data for each area. The data includes the operating state of the curtain, light intensity and infrared radiation intensity. The operating states of the intelligent curtain include: open state and closed state. When the light is too strong / when the detected temperature is higher than the set temperature, the received signal is fed back to the main control unit, and the main control unit controls the curtain to close to prevent light from entering the room. The curtain can also be manually operated through the curtain controller to realize the opening and closing control of the curtain to enrich the control methods of the curtain. For example, at night, the "romantic dinner" scene can be started with one key, the curtain slowly closes, and the lighting circuit lights up softly, creating a warm and romantic atmosphere; in the early morning, the "wake-up in the morning" scene can be set, and the curtain automatically opens, allowing the warm sunlight to wake up a beautiful day together.

In summary, with its advantages such as multi-device linkage, energy conservation and environmental protection, the present switch linkage system provides an innovative solution for the smart home field.

[0051] Although the present application has been depicted and described as a balcony intelligent control system with a specific configuration, it should be understood that various changes, modifications, and equivalent substitutions can be made to the present application without departing from the spirit and scope of the present application. Therefore, for those skilled in the relevant art, after understanding the basic idea and specific implementation of the present application, many possible changes, modifications, and equivalent substitutions can be made, and these changes, modifications, and equivalent substitutions should all be regarded as falling within the protection scope of the present application.
