[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate for the embodiments of the present invention described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatuses.

[0024] According to an embodiment of the present invention, a remote controller is provided for communicating with a control box so as to control the use of smart furniture through the control box.

[0025] Figure 1 Schematic diagram of a remote controller according to an embodiment of the present invention, Figure 1 As shown, the remote controller includes: a remote controller main circuit 10 , a key wake-up circuit 20 and a timer wake-up circuit 30 .

[0026] Specifically, the remote control main circuit 10 is wirelessly connected to the control box in the target device, and is used to respond to the search instruction when receiving the search instruction sent by the control box, wherein the search instruction is used to find the remote control, and the remote control is used to control the target device; the key wake-up circuit 20 is electrically connected to the remote control main circuit 10, and is used to control the remote control main circuit 10 to be powered off when it is detected that no key is pressed, and to control the remote control main circuit 10 to be in a standby state after a first preset time period; the timer wake-up circuit 30 is electrically connected to the remote control main circuit 10, and is used to control the remote control main circuit 10 to be powered on according to a preset time interval when the remote control main circuit 10 is in the standby state, and to control the remote control main circuit 10 to be in a wake-up state within a second preset time period.

[0027] Optionally, in the remote controller provided by an embodiment of the present invention, the second preset duration is smaller than the duration corresponding to the preset time interval.

[0028] Among them, the T1 time when the remote control is in the awake state (corresponding to the second preset time length mentioned above) can be set to be less than the T2 time interval for waking up the remote control (corresponding to the preset time interval mentioned above), thereby extending the standby time of the remote control and shortening the wake-up time of the remote control, thereby achieving the effect of reducing the power consumption of the remote control.

[0029] For example, Figure 2 Schematic diagram of a remote controller and a control box according to an embodiment of the present invention, as shown in FIG. Figure 2 As shown, when a button is pressed on the remote control, the main circuit 10 of the remote control is powered and the MCU (Microcontroller Unit) starts working. At this time, the remote control is in working state and scans whether a button is pressed. If a button is pressed, the command information of the button is sent to the control box, and the control box receives the corresponding command information and performs relevant actions.

[0030] For example, when no button is pressed on the remote control, it will enter the standby state after T3 time (corresponding to the first preset time length mentioned above). At this time, only the timer wake-up circuit 30 is working. The timer wake-up circuit 30 will power the remote control main circuit 10 at an interval of T2 (corresponding to the above preset time interval). At this time, the remote control is in the wake-up state and lasts for T1 time (corresponding to the above second preset time length). It detects whether there is a command to find the remote control (corresponding to the above search instruction) sent by the control box. If no command information to find the remote control from the control box (corresponding to the above search instruction) is detected, it enters the standby state again. If a command to find the remote control from the control box (corresponding to the above search instruction) is received, the search module (buzzer or light) on the remote control is triggered to guide the user to find the remote control.

[0031] In addition, the control box is usually in the receiving state, receiving commands from the remote control. If you need to find the remote control, just press the search button on the control box. After pressing the search button, the control box switches to the sending state and continuously sends search commands to the remote control within T4 (for example, 30 seconds, T4 ≥ T1 + T2). After T4 time, the receiving state is restored until the next time the search button is pressed.

[0032] Optionally, in the remote control provided in the embodiment of the present invention, the frequency band used for communication between the remote control and the control box includes at least one of the following: a first communication frequency band and a second communication frequency band, wherein the first communication frequency band is a frequency band used for communication in units of data packets, and the second communication frequency band is a frequency band used for communication in units of bytes.

[0033] Moreover, there are two communication frequency bands between the remote control and the control box. For example, in the working state, the communication between the remote control and the control box through frequency band 1 (corresponding to the first communication frequency band mentioned above) is in data packets. However, only when the search button of the control box is pressed, the control box (sending state) continuously sends signals in bytes on frequency band 2 (corresponding to the second communication frequency band mentioned above). Therefore, within one cycle, the remote control can trigger the search module (buzzer or light) as long as it receives one byte when it is in the awake state (at this time in the receiving mode).

[0034] For another example, the remote control includes both a sending module and a receiving module. When entering the wake-up state, the sending module and the receiving module are enabled at the same time, that is, a search signal (special frequency band, in bytes) is sent to the control box within the T1 time (corresponding to the second preset time length mentioned above). The control box also includes both a sending module and a receiving module. The control box is always in the receiving state, and receives signals from frequency band 1 (data packet) and frequency band 2 (byte) at the same time. When the control box recognizes that it has received the signal from frequency band 2 (byte), it activates the sending module and sends a feedback signal to the remote control. When the receiving module of the remote control receives the feedback signal, it triggers the search module (buzzer or light) on the remote control to guide the user to find the remote control.

[0035] For example, the remote control of this solution controls the power-on of the entire remote control main circuit 10 through a parallel key wake-up circuit 20. There is no limit on the number of keys. When no key is pressed, the remote control main circuit 10 is not powered. After T3 time (corresponding to the first preset time length mentioned above), the remote control enters the standby state and the power consumption is zero. Only through an extremely low-power external timer (corresponding to the above-mentioned timer wake-up circuit 30, current consumption nA level), every T2 (corresponding to the above-mentioned preset time interval) time (for example, 10-20s), the remote control main circuit 10 is powered on and awakened. Each remote control awakening lasts for T1 (corresponding to the above-mentioned second preset time length) time (T1 is much smaller than T2, ms level). Within T1 time (corresponding to the above-mentioned second preset time length), the remote control is in the awakened state (at this time it is in the receiving mode), and it is determined whether there is a remote control search instruction (corresponding to the above-mentioned search instruction) sent by the control box. If the remote control search instruction (corresponding to the above-mentioned search instruction) from the control box is received, the search module (buzzer or light) is immediately turned on to guide the user to find the remote control. If the remote control search instruction (corresponding to the above-mentioned search instruction) from the control box is not received, the remote control enters the standby state again. This process consumes extremely small current (uA level), and each cycle lasts for T1+T2.

[0036] Moreover, the entire remote control circuit is simple, reliable, and low-cost. At the same time, the MCU and search module of this remote control are both wide-voltage devices, so even if the two batteries are seriously depleted, all functions can be used normally.

[0037] Therefore, the embodiment of the utility model provides a standby state with zero power consumption, and at the same time adds a remote control search function, which greatly increases the use cycle of the user's remote control. If the remote control cannot be found, you only need to press the button on the smart bed control box to find the location of the remote control.

[0038] Furthermore, the present invention primarily addresses the technical issue of remote control standby power consumption, achieving zero standby power consumption. Furthermore, if the remote control is lost, it can be quickly found with a simple operation. This significantly reduces user costs. Because the standby current is zero, the frequency of battery replacement is significantly reduced. Furthermore, if the remote control is lost, it can be quickly found with a simple operation, improving the user experience.

[0039] In summary, the remote control provided by the embodiment of the present invention is wirelessly connected to the control box in the target device through the remote control main circuit 10, and is used to respond to the search instruction when receiving the search instruction sent by the control box, wherein the search instruction is used to find the remote control, and the remote control is used to control the target device; the key wake-up circuit 20 is electrically connected to the remote control main circuit 10, and is used to control the remote control main circuit 10 to be powered off when it is detected that no key is pressed, and to control the remote control main circuit 10 to be in a standby state after a first preset time period; the timer wake-up circuit 30 is electrically connected to the remote control main circuit 10, and is used to control the remote control main circuit 10 to be powered on according to a preset time interval when the remote control main circuit 10 is in the standby state, and to control the remote control main circuit 10 to be in a wake-up state within a second preset time period, wherein the second preset time period is less than the time period corresponding to the preset time interval, thereby solving the problem in the related art that the standby power consumption of the remote control used to control the target device is large, and it is difficult to find the remote control in time, resulting in poor use of the remote control. The key wake-up circuit 20 is used to control the power-on of the entire remote control main circuit 10. When the key is not pressed, the remote control main circuit 10 is not powered. After T3 time (i.e., the first preset time length), the remote control enters the standby state with zero power consumption. Then, only an extremely low-power timer wake-up circuit 30 is used to wake up the remote control main circuit 10 every T2 time (i.e., the preset time interval). Each remote control wake-up lasts for T1 time (i.e., the second preset time length, and T1 is much smaller than T2). During T1 time (i.e., the second preset time length), the remote control is in the awake state (at this time, it is in the receiving mode), and the judgment is made. It is determined whether there is a remote control search command (i.e., search command) sent by the control box. If the remote control search command (i.e., search command) is received from the control box, the search module (buzzer or light) is immediately turned on to guide the user to find the remote control. If the remote control search command (i.e., search command) is not received from the control box, the system enters the standby state again. This process consumes very little current, and each cycle lasts for T1+T2, thereby reducing the standby power consumption of the remote control and increasing the service life of the remote control. In addition, if the remote control is lost, the remote control can be found quickly, thereby improving the use effect of the remote control.

[0040] Optionally, in the remote control provided in an embodiment of the present invention, the timer wake-up circuit 30 includes a first capacitor, an integrated circuit, a first resistor, a second resistor and a third resistor; the first end of the first capacitor is electrically connected to the positive pole of the first power supply, the first pin of the integrated circuit and the first end of the first resistor; the second end of the first capacitor is electrically connected to the first ground terminal and the second pin of the integrated circuit; the second end of the first resistor is electrically connected to the sixth pin of the integrated circuit; the first end of the second resistor is electrically connected to the third pin of the integrated circuit, and the second end of the second resistor is electrically connected to the second ground terminal; the first end of the third resistor is electrically connected to the fifth pin of the integrated circuit; and the fourth pin of the integrated circuit is electrically connected to the microcontroller in the remote control main circuit 10.

[0041] For example, Figure 3 Schematic diagram of the circuit in the remote controller in the embodiment of the present utility model, as shown in FIG. Figure 3 As shown, the connection relationship between the components in the timer wake-up circuit 30 can be as follows: the first end of the capacitor C1 (corresponding to the above-mentioned first capacitor) is electrically connected to VCC (corresponding to the above-mentioned first power supply positive electrode), the first pin of the chip U1 (corresponding to the above-mentioned integrated circuit), and the first end of the resistor R1 (corresponding to the above-mentioned first resistor); the second end of the capacitor C1 (corresponding to the above-mentioned first capacitor) is electrically connected to GND (corresponding to the above-mentioned first ground terminal) and the second pin of the chip U1 (corresponding to the above-mentioned integrated circuit); the second end of the resistor R1 (corresponding to the above-mentioned first resistor) is electrically connected to the sixth pin of the chip U1 (corresponding to the above-mentioned integrated circuit); the first end of the resistor R2 (corresponding to the above-mentioned second resistor) is electrically connected to the third pin of the chip U1 (corresponding to the above-mentioned integrated circuit), and the second end of the resistor R2 (corresponding to the above-mentioned second resistor) is electrically connected to GND (corresponding to the above-mentioned second ground terminal); the first end of the resistor R3 (corresponding to the above-mentioned third resistor) is electrically connected to the fifth pin of the chip U1 (corresponding to the above-mentioned integrated circuit); and the fourth pin of the chip U1 (corresponding to the above-mentioned integrated circuit) is electrically connected to the microcontroller in the remote control main circuit 10.

[0042] In summary, the circuit diagram of the timer wake-up circuit can be obtained quickly and accurately, and the remote control can be woken up by the timer wake-up circuit.

[0043] Optionally, in the remote control provided in the embodiment of the present invention, the remote control further includes: a switch circuit 40 electrically connected to the key wake-up circuit 20 and the timer wake-up circuit 30, for controlling whether the remote control main circuit 10 is powered on.

[0045] In summary, the power supply of the entire remote control can be conveniently controlled by using a switching circuit.

Figure 3As shown, the connection relationship between the components in the key wake-up circuit 20 can be as follows: the first end of the resistor R9 (corresponding to the ninth resistor) is electrically connected to the first end of the switch S1 (corresponding to the first switch), the second end of the resistor R9 (corresponding to the ninth resistor) is electrically connected to the base of the transistor N2 (corresponding to the second transistor), the first end of the resistor R8 (corresponding to the eighth resistor), the second end of the resistor R10 (corresponding to the tenth resistor), the second end of the resistor R11 (corresponding to the eleventh resistor), the second end of the resistor R12 (corresponding to the twelfth resistor), the second end of the resistor R13 (corresponding to the thirteenth resistor), the second end of the resistor R14 (corresponding to the fourteenth resistor), and the second end of the resistor R15 (corresponding to the fifteenth resistor); the second end of the switch S1 (corresponding to the first switch) is electrically connected to the second end of the switch S2 (corresponding to the second switch), the second end of the switch S3 (corresponding to the third switch), the second end of the switch S4 (corresponding to the fourth switch). a first end of the resistor R12 (corresponding to the twelfth resistor) is electrically connected to the first end of the switch S4 (corresponding to the fourth switch), a first end of the resistor R13 (corresponding to the thirteenth resistor) is electrically connected to the first end of the switch S5 (corresponding to the fifth switch), a first end of the resistor R14 (corresponding to the fourteenth resistor) is electrically connected to the first end of the switch S6 (corresponding to the sixth switch), and a first end of the resistor R15 (corresponding to the fifteenth resistor) is electrically connected to the first end of the switch S7 (corresponding to the seventh switch).

[0051] In summary, the circuit diagram of the key-press wake-up circuit can be determined quickly and accurately, and the power-on of the entire remote control circuit can be controlled by the key-press wake-up circuit.

[0052] Optionally, in the remote control provided in an embodiment of the present invention, when the bases of the first transistor and the second transistor do not have a high level, the first field-effect transistor is controlled not to be turned on, and the remote control main circuit 10 is controlled to be in a standby state; or, when it is detected that any button is pressed, the base of the second transistor has a high level, the first field-effect transistor is controlled to be turned on, and the remote control main circuit 10 is controlled to be powered on.

[0053] For example, Figure 3 Schematic diagram of the circuit in the remote controller in the embodiment of the present utility model, as shown in FIG. Figure 3As shown, when the bases of transistor N1 (corresponding to the first transistor mentioned above) and transistor N2 (corresponding to the second transistor mentioned above) do not have a high level, MOS transistor Q1 (corresponding to the first field effect transistor mentioned above) is not turned on, and the battery power does not enter the remote control main circuit 10 through MOS transistor Q1 (corresponding to the first field effect transistor mentioned above). At this time, the current is 0, and this state is the standby state.

[0054] For another example, Figure 3 Schematic diagram of the circuit in the remote controller in the embodiment of the present utility model, as shown in FIG. Figure 3 As shown, when any button is pressed, the base of transistor N2 (corresponding to the second transistor mentioned above) has a high level, causing MOS transistor Q1 (corresponding to the first field effect transistor mentioned above) to be turned on, and the remote control main circuit 10 is powered.

[0055] In summary, the MOS tube can be used to conveniently control the remote control to enter the standby state and control the power supply of the remote control main circuit.

[0056] Optionally, in the remote control provided in an embodiment of the present invention, when the remote control main circuit 10 is in standby state, the timer wake-up circuit 30 gives a high level to the base of the first transistor according to a preset time interval, controls the first field effect transistor to be turned on, and controls the remote control main circuit 10 to be powered on.

[0057] For example, Figure 3 Schematic diagram of the circuit in the remote controller in the embodiment of the present utility model, as shown in FIG. Figure 3 As shown, in the standby state, the timer wake-up circuit 30 will give the base of the transistor N1 (corresponding to the first transistor mentioned above) a high level at a period of about 10 seconds to 20 seconds, causing the MOS transistor Q1 (corresponding to the first field-effect transistor mentioned above) to be turned on. At this time, the remote control main circuit 10 is energized, allowing the remote control main circuit 10 to detect whether there is a remote control search command from the control box. If no remote control search signal from the control box is detected, the remote control main circuit 10 enters the standby state in a very short time.

[0058] In summary, by controlling the conduction of the MOS tube, the power supply of the remote control main circuit can be conveniently controlled.

[0059] Optionally, in the remote controller provided by the embodiment of the present utility model, when the first field effect transistor is in the off state, the main circuit 10 of the remote controller is controlled to be powered off.

[0060] For example, Figure 3 Schematic diagram of the circuit in the remote controller in the embodiment of the present utility model, as shown in FIG. Figure 3As shown, this circuit cleverly designs two wake-up sources. The MOS transistor Q1 (corresponding to the first field-effect transistor mentioned above) is used as a switch to control whether the entire remote control is powered. At the same time, when the MOS transistor Q1 (corresponding to the first field-effect transistor mentioned above) is turned off, the entire remote control main circuit 10 is not powered and the power consumption is zero.

[0061] In summary, by controlling the MOS tube to be in the off state, the main circuit of the remote control can be conveniently controlled to be without power.

[0062] Optionally, in the remote controller provided by the embodiment of the present utility model, when the remote controller main circuit 10 does not receive a search instruction sent by the control box, the remote controller main circuit 10 is controlled to be in a standby state.

[0063] For example, when the remote control is in the awake state and lasts for T1 time (corresponding to the second preset time length mentioned above), it detects whether there is a command sent by the control box to find the remote control (corresponding to the above-mentioned search instruction). If no command information of the control box to find the remote control (corresponding to the above-mentioned search instruction) is detected, it enters the standby state again; if a command of the control box to find the remote control (corresponding to the above-mentioned search instruction) is received, the search module (buzzer or light) on the remote control is triggered to guide the user to find the remote control.

[0064] In summary, the remote controller can be conveniently and quickly controlled to be in the standby state, thereby reducing the power consumption of the remote controller.
