The invention discloses an automatic cut-off conversion socket for electric apparatus standby. The socket comprises at least one standby detection socket, wherein a power metering chip, a controller and a power relay are arranged on each standby detection socket, the power metering chip is used for detecting the output power of the standby detection socket and for sending standby information to the controller when the output power is lower than a preset value, the controller is used for counting when the standby information is received and for separately disconnecting the controller after a preset time. The socket is applied to the study of zero power consumption standby and safe standby technology, and can better solve the standby energy consumption problem; moreover, an intrinsic safety standby standard is proposed, which has an appreciable promotion function for the technological advance of the household appliances industry; extra waste of the electrical energy can be greatly reduced every year; the emission of carbon dioxide and other greenhouse and harmful gases is reduced; the electric apparatus fire hazard is reduced; the damage to human health caused by standby electromagnetic radiation is reduced, and the service life of the electric apparatus is prolonged.

The invention relates to the technical field of electronic products, and discloses a startup and shutdown system. The startup and shutdown system comprises a startup and shutdown module, a startup and shutdown key and an MCU intelligent control module, wherein the startup and shutdown module comprises a startup trigger circuit, a trigger time-delay circuit, a startup and shutdown enable circuit and an MOS switch; when the system is started up, the startup and shutdown key is triggered, a startup trigger circuit is enabled to be conducted through the trigger time-delay circuit and input of a power supply, the startup trigger circuit drives the startup and shutdown enable circuit so as to turn on the MOS switch, the power supply is inputted into the MCU intelligent control module, the MCU intelligent control module operates and locks the startup and shutdown enable circuit so as to main conduction of the MOS switch; and when the system is shut down, the startup and shutdown key is triggered again, the MCU intelligent control module detects the startup and shutdown key, data is stored, the process is terminated, and the startup and shutdown enable circuit is released so as to enable the MOS switch to be turned off. According to the invention, reuse of one key can be met, and startup and shutdown of the system can be completed intelligently with zero standby power consumption.

The invention discloses an intelligent control method for standby power consumption of an electric appliance. The method comprises the following steps: obtaining a real-time current flowing through an electric appliance; setting a current reference value I and determining whether the electric appliance is in a normal operation status or in a standby status; obtaining a duration time of the standby status of the electric appliance; setting a time parameter T and determining whether a switch needs to cut off the power supply of the electric appliance or not. By use of the method, the problem of standby power consumption of electric appliances at present is effectively solved, the waste of resource is greatly reduced, and energy saving and emission reduction are achieved. The intelligent control method has a wide application in the field of intelligent switches.

The invention discloses an X capacitor bleeding control method. The method includes the following steps that: pulse signals outputted by a zero crossing detection circuit are received in real time; whether the pulse signals are zero or not is judged; and first control signals for controlling the switching on of an AC load are generated and transmitted when it is judged that a time period during which the pulse signals are not zero exceeds a first preset time, wherein the AC load responds to the first control signals and is switched on so as to bleed stored energy of an X capacitor. According to the X capacitor bleeding control method provided by the invention, the AC load begins working only when it is judged that the pulse signals are not zero and the time period during which the pulse signals are not zero exceeds the first preset time, namely, after a power source is switched off, and therefore, the AC load will not consume the energy of a circuit in a time period when the AC load is not required to work, and thus, the problem of standby power consumption in prior art can be solved.

The present application proposes an RRC state control method, device, mobile terminal and readable storage medium, which relate to the communication field. In this application, when the RRC state of the mobile terminal is in the RRC connection state, it is detected whether the mobile terminal is performing data transmission with the communication base station, and when there is no data transmission, the data detection timer is started, and then within the timer duration of the data detection timer Continuously detect whether the mobile terminal is performing data transmission with the communication base station, and finally when no data transmission is found within the entire timer duration, the mobile terminal releases the RRC connection by itself, and adjusts the RRC state from the RRC connection state to the RRC idle state, so that The mobile terminal runs directly in the RRC idle state, avoiding the continuous generation of standby power consumption while waiting for data transmission, thereby reducing the power consumption of the mobile terminal, prolonging the running time of the mobile terminal, and improving user experience.
