2. Description of Related Art
Nowadays, a phone-controlled electric door connects to a phone. After connecting, a password is inputted into the phone, and the electric door can be opened after comparing and certifying the password. It costs a sufficient communication fee to open the electric door each time. It accumulates a big expense over a long period of time. Besides, it is not only the cost of the communication fee, but it also occupies the public channel that results in the waste of public goods. Furthermore, the conventional security controlled method uses a password with four digits. It is easy for some people to decode and may result in insecurity.

The main objective of the present invention is to provide an improved mobile-controlled electric entrance device. The mobile-controlled electric entrance device comprises an electrically powered entrance body and a control unit. The control unit includes 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. The control unit is adapted to be controlled by a mobile phone wirelessly. The storage unit stores a plurality of predetermined phone numbers. The mobile phone number comparison unit receives a call from the mobile phone and demodulates the same to compare a phone number of the call with the predetermined phone numbers to generate a comparison result. An output operation is blocked by the delay and sequential logical decoding unit to prevent an error operation. The oscillation timer is electrically connected to the delay and sequential logical decoding unit to provide a necessary internal timing. If the phone number is not found in the predetermined phone numbers based on the comparison result, the mobile phone number comparison unit returns to a stand-by state. If the phone number is found in the predetermined phone numbers based on the comparison result, the mobile phone number comparison unit transmits a signal to trigger the oscillation timer to generate a sequential pulse. The delay and sequential logical decoding unit is controlled to operate the current driver and the relay switch according to the sequential pulse for opening or closing the electrically powered entrance body.
By utilizing the invention, the following advantages are obtained. First, the present invention is able to compare and confirm the 8-11 digit phone numbers as the password before the mobile phone is connected (pick-up). The present invention can reset the output to prevent error operation when comparing the phone number. Therefore, according to the present invention, the operation does not cost excessive communication fee, and, thus, it is more economical. Thus, the present invention can effectively use the public goods and guarantee safety.
Second, in the present invention, the oscillation timer further generates a sequential pulse itself. The delay and sequential logical decoding unit decides to open or close the electrically powered entrance body according to a ringing time (not the number of ring pulses) of a mobile controller. For example, a first short call can open the electrically powered entrance body, and a next second short call can close the electrically powered entrance body, or a first short call can open the electrically powered entrance body, and a next second long call can close the electrically powered entrance body. Thus, there are no complex instructions in the present invention. The present invention can save a lot of communication expense and can be adapted to many common locks or electric doors.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

Preferably, the control unit 10 is further in parallel connection with a communication device 20. The communication device 20 can be a telephone, a facsimile or a modem. The communication device 20 can be used for displaying the number of an incoming call or adding other functions.
Preferably, the control unit 10 is further electrically connected to a door-opened feedback unit 30. Thus, a user can check and confirm if the electrically powered entrance body is opened or closed at any time to guarantee the safety effectively.
Preferably, the door-opened feedback unit 30 is a reed switch alarm.
Preferably, the control unit 10 is further electrically connected to an alarm termination unit 40. The alarm termination unit 40 is connected to a security unit. When the electrically powered entrance body is opened, the alarm termination unit 40 can turn off the alarm from the security unit at the same time.
Preferably, the control unit 10 is further electrically connected to a mobile calling unit 50 for getting a car. Therefore, the user can wirelessly call his/her car to be positioned. It can effectively help a user to find his or her car earlier and more conveniently.
Preferably, the electrically powered entrance body is a cathode lock-style door, an anode lock-style door, an electronic lock-style door, a roller door, a roller window, a fence-style door in a driveway, an entrance of a parking tower and so on.
Preferably, the delay and sequential logical decoding unit 14 is a logical circuit. The delay and sequential logical decoding unit 14 provides logical function to delay, control and output according to different sequential signals transmitted from the oscillation timer 13 to meet the needs of various roller doors.
Preferably, the oscillation timer 13 further generates a sequential pulse. The delay and sequential logical decoding unit 14 decides to open or close the electrically powered entrance body according to a ringing time of a mobile controller. The mobile controller is the mobile phone.
Preferably, the current driver 15 is a circuit including transistors. Because utilizing TTL or CMOS cannot directly drive a relay, the circuit including transistors is designed for switching the relay on. Besides, the relay switch 16 is the interface between the electrically powered entrance body and the control unit 10.
Moreover, by utilizing pulses and transmitting signals in the present invention, a first short call can open the electrically powered entrance body, and a next second short call can close the electrically powered entrance body, or a first short call can open the electrically powered entrance body, and a next second long call can awaken and close the electrically powered entrance body.

There are several characteristics in the present invention. First, while the mobile-controlled electric entrance device is switched on or off and at this time, its circuit transmits a “reset” or “clean” signal to prevent interfering that may cause a mistaken operation.
Second, when the mobile phone number comparison unit 11 is operated, the incoming signal can be filtered from the predetermined phone numbers in a disconnected state (free of charge). If the comparison result indicates that the phone number is one of the predetermined phone numbers, the mobile phone number comparison unit 11 transmits a pulse to trigger the oscillation timer 13. Then, the oscillation timer 13 can transmit a pulse having different time widths. Two pulses having different time widths can be compared and logically outputted to switch on the relay via the current driver 15.
Third, according to different styles of electric doors, the present invention differentiates the output state in accordance with the period of the ringing time. The present invention can be adapted to have various kinds of push buttons and can generate a sequential signal (not according to the ringing times of a telephone and telegraph office) to determine to close or open the door according to how long the ringing lasts.
The present invention can include two circuit boards. One of the two circuit boards is adapted to have a logical processing function and includes a one shot IC and a logical determination IC. The other of the two circuit boards is adapted to recognize the phone numbers, switch on the relay, etc.
Besides, when the operator is at a distant place, a series connection can be applied with a reed switch alarm for ensuring the operation of opening and closing the door normally (as shown in
