Embodiments of this application provide a data sending method, an apparatus, a device, and a readable storage medium. A server determines a first transmission point from a coordinated set, and determines a first downlink sending weight of the first transmission point. Then, the server determines a second downlink sending weight of a second transmission point based on the first downlink sending weight, and sends the second downlink sending weight to the second transmission point. When sending a data stream to an electronic device, the second transmission point determines a downlink sending weight corresponding to the data stream from a matrix, weights the data stream, and sends the weighted data stream to the electronic device.

Data sending method, apparatus, device, and readable storage medium

A monitor includes a display device, a signal interface, a power interface, and a power controller. The display device is configured for displaying information to users. The signal interface is configured for receiving display signals, and providing the display signals for the display device. The power interface is configured for receiving power from an external power source, and providing the source for the display device. The power controller monitors the existence of the display signal at the signal interface, and accordingly controls the power interface to selectively provide the power for the display device.

An automatic power supply converting circuit includes a live input terminal, a neutral input terminal, a relay, a regulator, a voltage divider circuit, an identifying circuit, a switch circuit and a voltage doubling circuit. The live input terminal and the neutral input terminal are configured for receiving a first alternating current (AC) voltage. The regulator is configured for filtering and steadying the first AC voltage and outputting a regulated voltage. The voltage divider circuit is configured for sampling the first AC voltage and outputting a divided voltage. The identifying circuit is configured for comparing a divided voltage with a reference voltage, and outputting a control signal. The switch circuit is configured for controlling the relay to be conductive or not. The voltage doubling circuit is capable of being controlled by the relay and outputting a doubled voltage.
