Wireless control automatic switching-off device

Abstract

A wireless control automatic power-off device, which is composed of a socket body and multiple wireless transmitters, the socket body is composed of a regulated power supply circuit, a wireless receiving circuit and an execution circuit, and the regulated power supply circuit supplies the wireless receiving circuit, the execution circuit Provide working power, the signal output end of the wireless receiving circuit is connected with the input end of the execution circuit, and the normally open contact K of the relay J in the execution circuit is connected in series between the AC 220V power supply and the socket body. The wireless transmitter is composed of a wireless transmitting circuit and a USB plug, and the working power of the wireless transmitter is provided by the computer through the USB plug. The invention has the beneficial effects of safety, energy saving and prolonging the service life of equipment.

Description

technical field [0001] The invention relates to an automatic power-off device, in particular to a wireless-controlled automatic power-off device. Background technique [0002] After the computer is turned off, some devices that serve the computer, especially those that serve multiple computers, such as modems and routers, continue to work. These devices are generally installed in hidden places and are not easy to switch on and off. Since these devices are shared by multiple computers, turning off these devices after one computer is turned off will affect the use of other computers, so these devices are in a 24-hour working state all day long. It not only wastes electric energy, but also has potential safety hazards, and also reduces the service life of these devices. [0003] There is a wireless remote control socket at present, which can control the opening and closing of the socket by a remote controller, but there is no automatic switch function, and sometimes it is no...

AI Technical Summary

Problems solved by technology

These devices are generally installed in hidden places and are not easy to switch on and off. Since these devices are shared by multiple computers, turning off these devices after one computer is turned off will affect the use of other computers, so these devices are in a 24-hour working state all day long.

Not only wastes electric energy, but also has potential safety hazards, and also reduces the service life of these devices

[0003] At present, there is a wireless remote control socket, which can control the opening and closing of the socket through the remote control, but it does not have the function of automatic switch. Sometimes it is not known whether other computers are still working, so it is not known whether the socket power should be turned off.
