Abstract:
1. An outdoor extension line socket enabling remote controlled timing power supply, comprising: a socket body, in which the bottom of the socket body is formed as a tapered body, a socket is installed on one side of the socket body, a socket power control circuit is installed inside the socket body and an extension line plug extends from the socket body for input of alternating current (AC) power, in which the socket power control circuit consists of an AC power input module, a relay, a relay driving module, an AC power output module, a microprocessor, an oscillator, an RF decoder and an RF signal receiving module, in which the AC power input module inputs AC power via the extension line plug of the socket body, the oscillator and the RF signal receiving module connected to the microprocessor of the socket power control circuit are responsible for selectively receiving a constant RF signal which is decoded by the RF decoder, then the power supply time designated by the remote controller body is inputted into the microprocessor of the socket power control circuit so as to count the designated power supply time; then the microprocessor drives the relay driving module to control the conductivity in the relay such that the AC power output module outputs AC power by way of the socket; in addition, at the end of the designated power supply time counted by the microprocessor, the relay driving module is driven so as to control the break in the relay thereby interrupting AC power outputted by the socket; and a remote controller body, which emits a radio frequency (RF) signal to the socket body, wherein a time adjustment wheel, a switch control button are installed on the surface of the controller body, and a remote control circuit is installed inside the remote controller body, in which the remote control circuit is used to remotely control the socket body and consists of a battery, a switch control input module, a microprocessor, an oscillator, an RF encoder, a wheel signal input module and an RF signal emitting module, in which the battery is interfaced with the switch control input module and the microprocessor thereby providing electric power for activation of the remote controller body, and also, the oscillator and the RF encoder connected to the microprocessor of the remote control circuit to convert the power supply time designated by the wheel signal input module into an RF signal, and then the microprocessor drives the RF signal emitting module so as to transfer the RF signal to the socket body, thus the remote controller body is allowed to adjust the power supply time used to set the socket body.
