Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail by embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to be limiting. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
As an embodiment, the single-key remote controller in fig. 1 has a key 10, a first analog switch 20, a second analog switch 30, a first diode 40, a second diode 50, a single chip microcomputer 60, and a remote control transceiver unit 70. A first terminal of the key 10 is electrically connected to the positive power supply electrode Vbat, and a second terminal of the key 10 is electrically connected to an anode of the first diode 40 and an anode of the second diode 50. The first end of the first analog switch 20 is electrically connected with the positive power supply electrode Vbat, the second end of the first analog switch 20 is electrically connected with the power supply terminal VCC1 of the single chip microcomputer 60 and the cathode of the first diode 40, and the control end of the first analog switch 20 is electrically connected with the first GPIO of the single chip microcomputer 60. The first end of the second analog switch 30 is electrically connected with the cathode of the second diode 50, the second end of the second analog switch 30 is electrically connected with the second GPIO of the single chip microcomputer 60, and the control end of the second analog switch 30 is electrically connected with the first GPIO of the single chip microcomputer 60. The common end GND1 of the single chip microcomputer 60 is electrically connected with the negative electrode of the power supply and the common end GND2 of the remote control transceiver unit 70, and the single chip microcomputer 60 is connected with the remote control transceiver unit 70 through a communication interface which adopts UART or SPI. The power supply terminal VCC2 of the remote control transceiver unit 70 is electrically connected with the power supply terminal VCC1 of the single chip microcomputer 60.
The first diode 40 and the second diode 50 are schottky diodes and have a relatively small tube voltage drop during operation.
After the single chip microcomputer 60 is powered on, the first GPIO is set as output, and the second GPIO is set as input. The first analog switch 20 and the second analog switch 30 are both of a normally-open type having pull-down resistors at their control terminals and second terminals. The pull-down resistor at the control end ensures that the two analog switches are disconnected when the single chip microcomputer 60 loses power supply, namely, the two analog switches are kept in a normally open state. The pull-down resistor at the second end of the analog switch has the effect of quickly powering down the first analog switch 20 after the singlechip 60 loses power supply, and the effect of the second analog switch 30 is that the second GPIO input can be ensured to be low level if the key 10 is switched off when the singlechip 60 normally works.
When the single chip microcomputer 60 is powered off, the key 10 is pressed down, the single chip microcomputer 60 is powered on, the first GPIO output is high, the two analog switches of the first analog switch 20 and the second analog switch 30 are conducted, the single chip microcomputer 60 and the remote control transceiving unit 70 are powered and self-locked, and the key 10 enables the positive pole Vbat of a power supply to be connected into the second GPIO of the single chip microcomputer 60 through the second diode 50. The single chip microcomputer 60 collects the operation state of the key 10, and sends out a remote control command and receives a return command through the remote control transceiving unit 70, and at this time, the key 10 can perform various operations to achieve the purpose of interactive control with the controlled device. After the operation of the key 10 is completed, the first GPIO output of the single chip microcomputer 60 is low, and enters a non-power-supply state.
The remote control transceiver unit 70 is a FABRIC wireless internet communication module, and CN106878440B discloses a forward addressing and reverse re-addressing internet communication (FABRIC) method, device and system, wherein the device based on FABRIC wireless internet communication maintains a neighbor device list, each device indicates existence by sending BEACON frame regularly, therefore, the single chip microcomputer 60 obtains MAC address, device type and RSSI of surrounding FABRIC devices through the remote control transceiver unit 70 and forms a device list, selects a device by interacting with the surrounding devices through key operation, or selects a device by taking maximum RSSI value and device type as controllable conditions, and stores the MAC address of the device in the nonvolatile storage unit of the single chip microcomputer.
The above process of selecting a controlled device is further described as follows: the key 10 is pressed when the single chip microcomputer 60 is in a non-power supply state, long pressing is maintained for at least 4 seconds, the single chip microcomputer 60 starts self-locking power supply after the moment when the key 10 is pressed, and then the key 10 is detected to be pressed for 4-10 seconds to determine that an equipment selection process is entered; the single chip microcomputer 60 acquires the MAC addresses, device types, and RSSIs of peripheral FABRIC devices through the remote control transceiving unit 70 within 4 to 10 seconds after the key 10 is pressed down and forms a device list, in one case, the single chip microcomputer 60 initiates access control on each peripheral FABRIC device in turn, when a user observes that a device to be controlled, such as a lamp, is lighted up, the key 10 is clicked for confirmation, if not, the key 10 is not operated, the single chip microcomputer 60 monitors the feedback information of the key 10 and records the MAC addresses of the corresponding FABRIC devices, such as the lamp, to the nonvolatile storage unit of the single chip microcomputer 60 as a specific object for subsequent control; another situation is that the user brings the remote controller close to the specific object device type as controllable, such as the lamp, so that the RSSI of the device is strongest, and the single chip microcomputer 60 selects the MAC address of the device from a plurality of devices and stores the MAC address in the nonvolatile storage unit of the single chip microcomputer 60; after the selection is completed, the single chip microcomputer 60 outputs the first GPIO as low to enter a non-power-supply state.
After the controlled equipment is selected to operate, the key 10 is pressed down subsequently, the duration time is within 4 seconds, the single chip microcomputer 60 judges that the specific object is operated, and due to the adoption of FABRIC wireless interconnection communication, remote control can be realized through forwarding of the intermediate equipment between the remote controller and the specific object.
In addition, fig. 2 shows an embodiment of an analog switch, which includes a P-channel fet Q1, four resistors R1-R4, and an NPN triode or N-channel fet Q2, wherein a first end 201 of the analog switch is electrically connected to a source of Q1 and a first end of R1, a second end 202 of the analog switch is electrically connected to a drain of Q1 and a first end of a pull-down resistor R4, a control end 203 of the analog switch is electrically connected to a first end of the resistor R2, a second end of R2 is electrically connected to a first end of the pull-down resistor R3 and a base or gate of Q2, a collector or drain of Q2 is electrically connected to a second end of R1 and a gate of Q1, and an emitter or a source of Q2 is electrically connected to a second end of R3 and a second end of R4 is electrically connected to a negative terminal of a power source. When Q2 is off, Q1 is off and the analog switch first terminal 201 is disconnected from the analog switch second terminal 202. When Q2 is on, Q1 is on and the analog switch first terminal 201 is in communication with the analog switch second terminal 202. The leakage current of Q2 consumes power when the remote controller is in standby mode, the NPN transistor is about 0.1uA, and the N-channel fet is about 1 uA.
Fig. 3 is another embodiment, and the difference from fig. 1 is that the single chip microcomputer 60 and the remote control transceiver unit 70 in fig. 1 are combined into an SOC system-on-chip 80, and the other parts in the figure correspond to fig. 1 and are not described again.
