Time control socket

Abstract

The invention discloses a time control socket which comprises a rotary knob, an encoder, a clock chip, a relay RJ, a relay driving module, a microprocessor and a display portion. The encoder inputs corresponding rotation signals generated by rotation of the rotary knob to the microprocessor to be processed, the microprocessor figures out the rotation direction and rotation angle of the encoder and sets reference time, the socket turn-on time and the socket turn-on time span, the clock chip provides reference time, the display portion receives output signals of the microprocessor, displays the corresponding time and indicates a time set mode of the microprocessor, and the microprocessor controls on-off of the relay RJ through the relay driving module and controls on-off of the time control socket. The time control socket can be automatically turned on or off at regular time according to the preset time, set time cannot be easily changed by misoperations of children, and the time control socket is safe and reliable in work, simple in appearance and convenient to operate.

Description

technical field [0001] The invention relates to an intelligent socket, in particular to a time-controlled socket. Background technique [0002] The socket or switch with time control function can automatically turn on and off the power of various electrical equipment according to the time set by the user, and can be used for power control of household appliances such as air conditioners, electric heaters, water heaters, lighting and rice cookers in ordinary households; It can also be used in factory workshop lighting, heating facilities and various production links that require precise time control; using such sockets or switches can be used for timing, time limit, energy saving and safe electricity use, which can avoid forgetting to turn off the power when no one is on duty. Electricity fire accidents caused. But the time setting of the socket or switch with time control function of the prior art usually needs to pass through a plurality of buttons, because there are many ...

Problems solved by technology

But the time setting of the socket or switch with time control function of the prior art usually needs to pass through a plurality of buttons, because there are many buttons, it takes up the surface space of the socket, and the operation is more complicated when setting the time. operation, it is easy to change the set time without the knowledge of adults, resulting in unnecessary waste of electricity and danger of electricity consumption
