First, after setting the signals output from the various remote controllers 10 including the unique codes assigned to the door lock system at the time of initial door lock installation, and driving the automatic door lock system, only the power receiver 12 is supplied to the first receiver 14. Supplied. At this time, since the method for setting the remote control output signal of the door lock system is already known, its detailed description will be omitted.

Subsequently, when a user outputs a predetermined wireless signal for opening or closing a door by operating the remote controller 10, the first receiving unit 14 receives the predetermined wireless signal, and the sensor outputs a signal output from the first receiving unit 14. When the pre-signal is detected by 32, the switch SW1 is turned on to supply power to the entire system including the second receiver 16 and the microcomputer 30 so that the system enters the standby mode.

Subsequently, when the microcomputer 30 detects a main signal related to opening / closing the door based on the signals output from the first receiver 14 and the second receiver 16, the microcomputer 30 controls the corresponding operation by the motor driver 20. The door is opened / closed by outputting a signal such that the motor 18 rotates forward or reversely, and the modem comparator signal is not output from the comparator 40.

On the other hand, when the user outputs the door open signal through the remote control 10 in the above configuration, while the motor 18 is rotated forward, the rotating body 46 engaged with the motor 18 is rotated, accordingly the rotating body The frame drive piece 48 formed longer than 46 is rotated by a predetermined angle, and then the frame 44 is reversed as shown in FIG. 3A while the rotation is suppressed. As a result, the slider 42 coupled to the frame 44 is retracted to open the door. When the user outputs a door close signal through the remote controller 10, various components including the motor 18 operate in reverse, and advance the slider 42 to lock the door as shown in FIG. 3B. .

However, when the microcomputer 30 or the motor driving unit 20 is broken in the door lock system as described above, even if the door open / close signal is received through the first receiving unit 14 and the second receiving unit 16, the motor driving unit Since the signal related to the motor drive is not output from the comparator 20, the comparator 40 outputs a modem preparation signal. In this process, the door opening through the telephone is necessary only when the door is locked, so that the auxiliary switch SW2 is turned on. This is possible only when the telephone line 36 and the modem 38 are connected, that is, the door is closed.

Then, when the user dials the telephone connected to the modem 38 and inputs a predetermined password and a predetermined signal according to the door opening, the modem 38 determines the signal input through the telephone line 36 to open the door. The operation signal is output to the auxiliary motor driver 34 only when there is a signal input related to opening. When the operation signal is output from the modem 38, the auxiliary motor driver 34 outputs a motor reverse rotation only signal to open the door. To be opened.

On the other hand, when it is impossible to open or close the door through the remote control 10 or open the door through the telephone, as shown in FIG. 3C, the door is located at the same position as the groove 51a of the middle rod 51 formed on the handle 54. When the 80 is drilled and the driver 51 is inserted into the groove 51a and rotated, the shaft bar 52 of the handle 54 is rotated to retract the frame 44 to open the door.

In addition, the automatic door lock system detects an impact or damage such as various theft detection sensors (for example, an impact sensor, a damage sensor, a human body detection sensor), and the theft detection sensor 84 outputs a signal corresponding thereto. If so, the buzzer 86 warns the user of this, a remaining amount detecting unit 88 for detecting a remaining amount of power and outputting a predetermined signal when the remaining amount of power is less than or equal to a predetermined value, and the remaining amount detecting unit 88. The display unit 89 is further provided to indicate the time to replace the power to the user by the signal output from the.

Therefore, according to the present invention, when the door lock through the remote control is broken, the door can be opened through the telephone. When the door lock is in the standby state, power is supplied only to the receiver, thereby saving power.

Therefore, according to the present invention, when the door opening and closing part through the remote control is broken, it is possible to automatically open the door through the phone, which is convenient to use, and the power saving effect is minimized when the standby state of the automatic door lock system is minimized. There is.
