Abstract
A power lock device for safe power output/input is a control lock composed of coding devices, decoding devices and electromagnetic switches. The coded signal will attach to the power transmitting line and keeps on transmitting. After discerning that the coded signal is correct, the decoding device turns on electromagnetic switches and conducts power to transmit. If the code is not correct, the decoding device uses the electromagnetic switches to cut off power and achieves the function of power control.
Claims6
A power lock device for safe power output/input, comprising:
- a power supply end for contrasting a code and controlling whether said power supply end transmits power or not;
- and
- a power receiving end sending said code to said power supply end to contract;
- a method for supplying power to said power receiving end from said power supply end, comprising the steps of:
- a. said power supplying end waiting for said code of said power receiving end and providing a safe low voltage to said power receiving end for operation, and
- b. supplying power to said power receiving end if said power supply end receives said code from said power receiving end is correct, whereby power is supplied to said power receiving end and from said power supply end.
