In the description of the present invention, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The control device for controlling the power of a remote controller and the workflow thereof according to the present invention are described below with reference to fig. 1-2. In which fig. 1 shows a circuit diagram of a circuit system of a remote control comprising a control device according to a preferred embodiment of the invention. Fig. 2 shows the workflow of the control device according to the invention.
The remote controller is an air conditioner remote controller, a television remote controller and the like. The leakage and decay phenomenon of the battery can occur when the existing remote controller is placed for a long time in the market. For example, even when the air conditioner remote controller is not in use, corresponding information can still be displayed on the display screen, which can cause energy waste and influence the service life of the remote controller. In order to solve the problems, the invention provides the control device for controlling the power supply of the remote controller. Fig. 1 shows a circuit diagram of a remote control comprising the circuitry of the control device according to the invention. As shown in fig. 1, the circuit system of the remote controller includes a power source E, a circuit to be powered, and the control device CL. The power supply E is, for example, a dry battery, and supplies power to the circuit to be powered. The control device CL includes a switching unit SW and a control unit 1. The switch unit SW is arranged between the power supply E and the circuit to be powered and is used for powering on or powering off the power supply of the circuit to be powered by closing or opening. That is, when the switching unit SW is closed, the power source E supplies power to the circuit to be supplied with power; when the switching unit SW is turned on, the circuit to be powered is powered off. The circuit to be powered is a circuit such as a control unit and a communication unit of a remote controller. The control unit 1 is configured to control the switching unit SW, open the switching unit SW in a state where the remote controller does not perform control operation, so as to disconnect power supplied from the power source E to the circuit to be powered, and control the switching unit SW to be closed when performing control operation by using the remote controller, so as to resume power supply to the circuit to be powered.
According to the above scheme of the invention, the control unit 1 is used for controlling the switch unit SW, so that the power supply E can be disconnected to supply power to the circuit to be supplied, and the switch unit is closed according to waking up when a remote controller is used, thereby automatically cutting off the power supply to reduce energy consumption and prevent the battery from leaking liquid, rotting and the like, and protecting the electric appliance from damage. The respective components of the control device of the present invention will be described one by one.
Specifically, in a preferred embodiment, as shown in fig. 1, the control unit 1 includes a wake-up module WK and a control module MCU. The wake-up module WK is connected between the power supply E and the control module MCU and is used for sending out a wake-up signal according to a user instruction under the condition that the switch unit SW is opened. And the control module MCU receives the wake-up signal of the wake-up module WK and then enables the switch unit SW to be closed, so that the power supply of the circuit to be powered is recovered. It should be noted that, in the embodiment shown in fig. 1, the control module MCU is shown separately from the circuit to be powered for convenience of description, but the control module actually also belongs to a part of the circuit to be powered, and may be disposed in a controller, such as a remote controller, to jointly implement each control function of the remote controller.
Further preferably, the control module MCU controls the switch unit SW to be turned on each time the remote controller completes a control operation for a predetermined time, that is, a remote controller does not have a control operation for a predetermined time, thereby disconnecting the power supply to the circuit to be powered. The control operation is a control operation of the remote controller on an electric appliance, and takes the electric appliance as an example of an air conditioner, for example, the control operation of adjusting the wind direction, the temperature and the timing of the air conditioner, and the opening or closing of the air conditioner is performed. The control module MCU includes a detector and a timer (not shown), the detector detects the control operation of the remote controller in a state where the switching unit SW is closed and the power source supplies power to the circuit to be powered, and transmits a detection signal to the timer after detecting the control operation, the timer starts the timing operation every time the detection signal is received, and controls the switching unit SW to be opened after a predetermined time, for example, 30 minutes, thereby cutting off the power supply E to the circuit to be powered. Specifically, when the remote controller controls the operation each time, the control module MCU has instructions to send out, and the timing is started after each instruction is sent out, so that the circuit is disconnected after the predetermined time is reached. The predetermined time may be empirically set to any suitable time, and the above 30 minutes are merely exemplary.
As shown in fig. 1, the switching unit SW preferably adopts a triode Q, the collector and the base of the triode Q are respectively connected to the positive and negative ends of the power supply E, and the base is simultaneously connected to the control module MCU. The control module MCU controls the connection and disconnection of the triode by controlling the voltage of the base electrode, so that the closing and opening of the switching unit SW are controlled. Preferably, a current limiting resistor R1 is connected between the base of the triode Q and the control unit SW for preventing damage to the device caused by excessive current. And further preferably, a first protection unit, such as a zener diode D1, is further connected between the base and the power source E, for ensuring that the base voltage of the triode Q is in a stable state, thereby ensuring the stability and reliability of the whole circuit. The zener diode D1 may be omitted if necessary. Further preferably, a second protection unit, such as a diode D2, is further connected between the collector and the emitter of the triode Q, for limiting the internal voltage of the circuit system, so as to ensure that the internal voltage of the circuit system of the remote controller is not too high, and ensure the stability and reliability of the circuit system. Furthermore, the switching unit SW is also implemented using a relay. And if the factors such as cost and the like are considered, the triode device is adopted as the optimal choice.
The wake-up module WK is connected between the power supply E and the control module MCU, when the switch unit is the triode Q, the wake-up module WK comprises a key K which is connected between the collector and the emitter of the triode Q, and when the key K is pressed, the switch-on is realized between the power supply E and the control module MCU, so that the control module MCU can control the switch unit SW to be closed, and the power supply E is recovered to the power supply of the power supply circuit. The wake-up module WK may be implemented by any key on the remote controller, such as a start key of the air conditioner. Preferably, the wake-up module WK further includes a current limiting resistor R2, configured to limit the impact current at the moment of power-up, and prevent the damage to the device caused by excessive current.
According to the scheme of the invention, the control device selects the components with lower cost, has simple control logic, further realizes the effect of low cost on the basis of realizing the reduction of energy consumption and preventing the leakage of the battery from damaging the electric appliance, and ensures that the scheme has stronger practicability in application. Meanwhile, the appearance structure of the remote controller is not affected, and the universality is strong.
The workflow of the above-described control device according to the present invention is described below with reference to fig. 2. As shown in fig. 2, the entire workflow of the control device may be divided into a wake-up operation, a run state, and a power-off operation. It should be noted that the above-mentioned process is merely for understanding and convenience of description, and is not limited to the scheme of the present invention. The following description will take the switching device SW as the triode Q and the wake-up device as the key K as an example.
[ wake-up operation ]
When the remote controller operates for the first time, the power supply E and the circuit to be powered are in a disconnected state, namely the switch unit SW is opened. When the user needs to use the remote controller, the user can press a key K serving as a wakeup module WK to perform wakeup operation. When the key K is pressed, the power supply E is connected with the control module MCU and the circuit to be powered on, the control module MCU reads the stored working information when the power is cut off last time and simultaneously sends out a control signal, and the base level of the triode Q serving as the switch unit SW is controlled to enable the triode Q to be conducted, so that the power supply E and the circuit to be powered on keep in a continuous power-on state, and the remote controller circuit system is awakened to enter the following running state.
[ running State ]
As described above, after the above wake-up operation is performed by the key K, the power source E continuously supplies power to the circuit to be powered through the triode Q, and the remote controller enters the operation state, and the subsequent working mode is the same as that of the existing remote controller.
[ Power-off operation ]
After each control operation of the remote controller is completed, the timer of the control module MCU starts to count. If the detector detects a control operation of the remote controller within the set predetermined time T, the timer counts again. On the other hand, if the predetermined time T is reached, the detector does not detect any control operation of the remote controller, the control module MCU preferably records the current working state first, then sends a control signal, and turns off the transistor Q by controlling the base level of the transistor Q, so that the power supply E is turned off to the circuit to be powered, and the circuit to be powered is in a power-off state. It is sufficient to wake it up again before the next use in the manner described for the wake-up operation above.
The control device and the workflow thereof of the present invention are described above. According to the scheme of the invention, the control unit is used for controlling the switch unit, so that the power supply of the power supply to the circuit to be powered can be disconnected, and the switch unit is closed according to waking up when the remote controller is used, so that the power supply can be automatically cut off, the energy consumption is reduced, the battery is prevented from leaking, rotting and the like, and the electric appliance is protected from damage. In addition, the control device of the invention selects components with lower cost, has simple control logic, further realizes the effect of low cost, and ensures that the application of the scheme has stronger practicability. Meanwhile, the appearance structure of the remote controller is not affected, and the universality is strong.
It is easy to understand by those skilled in the art that the above preferred embodiments can be freely combined and overlapped without conflict.
It will be understood that the above-described embodiments are merely illustrative and not restrictive, and that all obvious or equivalent modifications and substitutions to the details given above may be made by those skilled in the art without departing from the underlying principles of the invention, are intended to be included within the scope of the appended claims.
