Detailed ways

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

Please refer to Fig. 1-2, the embodiment of the present invention discloses a zero-power remote control, including SOC30, power supply battery 10, MCU20 and button 40, the SOC30 is electrically connected to the MCU20, and the power supply battery 10 The SOC30 and the MCU20 are respectively powered by a power supply circuit, the button 40 is connected to the MCU20, the power supply battery 10 is provided with an electronic switch 60 on the power supply circuit of the SOC30, and the MCU20 and the electronic The switch 60 is electrically connected. When the button 40 is operated, the MCU20 electrically triggers the electronic switch 60 to close, and the MCU20 sends the instruction of the button 40 for the SOC30 to execute; when the button 40 is not When operated, the electronic switch 60 opens.

It can be understood that when the electronic switch 60 is turned on, all the circuits and electronic components of the SOC30 are in a power-off state, that is, when the remote controller is in standby, the SOC30 will not affect the power of the power supply battery 10. Power loss is zero.

Specifically, the full name of the SOC30 is SystemonChip, that is, a system-on-chip. In this embodiment, the SOC30 can be WIFI_SOC. At this time, the remote controller based on the SOC30 is commonly called a WiFi remote controller; in other implementation modes , the SOC30 can also be a Bluetooth Mesh_SOC, at this time, the remote controller based on the SOC30 is commonly called a Bluetooth remote controller.

The full name of the MCU20 is MicrocontrollerUnit, that is, a micro control unit, commonly known as a single-chip microcomputer. The SOC30 is electrically connected to the MCU20, that is, the MCU20 can send a control instruction to the SOC30 through signal transmission, and then the SOC30 executes the instruction.

In this embodiment, the electrical connection between the SOC30 and the MCU20 may be as follows: respectively provide a serial interface on the SOC30 and the MCU20, and then use a data transmission line to connect the two serial interfaces , which is a serial communication connection between the SOC30 and the MCU20; Each is provided with a parallel interface, and then the two parallel interfaces are connected by using a data transmission line, which is a parallel communication connection between the SOC30 and the MCU20.

Further, the MCU20 includes a sleep module, and when the button 40 is operated, the sleep module can be awakened to make the operation of the button 40 effective; when the button 40 is not operated, the MCU20 is in a dormant state . It can be understood that the sleep module can make the MCU20 be in a dormant state when the button 40 of the remote controller is not operated, and make the MCU20 be in a power-off state in other circuits and components except the sleep module. , reducing the power consumption of the power supply battery 10 by the MCU 20 during standby.

The remote controller also includes an antenna 50 connected to the SOC 30 . It can be understood that when the antenna 50 is used for the operation of the SOC 30 , the signal transmission and reception are more stable and the distance is longer. Regardless of whether it is a WiFi remote controller or a Bluetooth remote controller, when the antenna 50 is provided, the signals sent or received are significantly enhanced.

In one of the implementation manners, the key 40 is a matrix key. At this time, the matrix keys may use any one of mechanical keys or touch keys.

In another implementation manner, the key 40 may also be an independent key. At this time, the independent key can still be either a mechanical key or a touch key.

To sum up, a zero-power remote controller of the present invention, when the remote controller is in a standby state, the electronic switch 60 is turned on, so that all circuits and electronic components of the SOC30 are in a power-off state, that is, The power loss of the power supply battery 10 by the SOC 30 during standby is zero, therefore, the service life of the battery can be improved and the user experience can be enhanced.
