Abstract:
1. A mobile-controlled electric entrance device comprising: an electrically powered entrance body; a control unit including a mobile phone number comparison unit, a storage unit, an oscillation timer, a delay and sequential logical decoding unit, a current driver, and a relay switch; and a door-opened feed back unit automatically activating a monitor signal to provide feedback whether the electrically powered entrance body is opened or closed; wherein the control unit is adapted to be controlled by a mobile phone wirelessly; wherein the storage unit stores a plurality of predetermined phone numbers, wherein the control unit is further electrically connected to the door-opened feedback unit; wherein the mobile phone number comparison unit receives a call from the mobile phone and demodulates the call to compare a phone number of the call with the plurality of predetermined phone numbers to generate a comparison result; wherein an output operation is blocked by the delay and sequential logical decoding unit to prevent error operation; wherein the oscillation timer generates first and second sequential pulses having different time widths and is electrically connected to the delay and sequential logical decoding unit to provide a necessary internal timing; wherein if the phone number is not found in the plurality of predetermined phone numbers based on the comparison result, the mobile phone number comparison unit returns to a stand-by state; wherein if the phone number is found in the plurality of predetermined phone numbers based on the comparison result, the mobile phone number comparison unit transmits a signal to trigger the oscillation timer to generate one of the first and second sequential pulses; and wherein the delay and sequential logical decoding unit is controlled to operate the current driver and the relay switch according to the one of the first and second sequential pulses generated by the oscillation timer for opening or closing the electrically powered entrance body.
