Title:
KEY CONTROL CIRCUIT, METHOD AND APPARATUS, DEVICE, STORAGE MEDIUM, AND REMOTE CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2024/007679
Kind Code:
A1
Abstract:
The present application relates to the technical field of electronics, and relates to a key control circuit, method and apparatus, a device, a storage medium, and a remote controller. The key control circuit comprises a key module, a power source module, a control module and a power supply control module. When operated, the key module is used for simultaneously turning on a path between the power source module and the control module and a key-coded signal trigger path. When a power source signal has been acquired in a power-off state, the control module is used for starting timing and outputting a first control signal to the power supply control module, wherein the first control signal is used for controlling the power supply control module to turn on, so as to supply power to the control module within a preset delay duration by means of the power source module; and after the key module is not operated within the preset delay duration, the control module is used for outputting a second control signal to the power supply control module, wherein the second control signal is used for controlling the power supply control module to turn off, such that the power source module stops supplying power to the control module. The present application is used to solve the problem of the power consumption of a remote controller being relatively high when same is in a standby state.
