Abstract

PURPOSE: An automatic phone-connection by a doorbell and uncontrolled-selectively ringing, is provided to alert emergency and burglars to a user when a home is empty, by discriminating whether or not user's family, through differentiating sounds of the doorbell according to the members. CONSTITUTION: An automatic phone-connection by a doorbell and uncontrolled-selectively ringing, comprises operations as follows. A locker/unlocker of a door lock has a same size as a wireless password transmitter, a key part. The transmitter is shaped in a key ring. A user memorizes passwords per family, and recognizes one by a communication distance of radio-wave, in uncontrolled approaching pattern, to output a sound corresponded to the password, so that the others can recognize the members. If a bell switch is pushed, when the user is out, the user connects to a visitor, with a cellular phone and an interphone, respectively. On special dates of the user's family, a celebrating melody sounds for a member, when the member enters an outdoor.

Description

Automatic connection of telephone by doorbell switch and no operation identification Next doorbell {CALL BELL}

The present invention is a non-operational password identification doorbell that recognizes the password by a non-operational proximity recognition method based on the communication distance of the radio wave and rings the doorbell sound specified by the password and the telephone number specified by the user is When you press the doorbell, you can automatically dial the designated phone number and automatically connect to the interphone with the voice content installed through the telephone line.If the specified wireless password is input to the receiver on the date set by the user, the user will ring the specified melody. Automatic door-to-door connection and door-to-door identification by one doorbell switch.

Conventionally, to ring the doorbell, visitors use it for a limited time, but there is the hassle of requiring physical operation to push the doorbell switch even when the family enters and exits every day, and the family in the house is a family or visitor when the doorbell rings In order to find out, it was inconvenient to use the monitor, ask the lens in the door, or indirectly to check it.In addition, when the user went out, it was inconvenient to contact the user even if an important visitor came to press the doorbell And there was no way to remind users by selectively responding to the designated persons such as wedding anniversary or birthday.

The present invention is to solve the problems as described above (application date: 1999.1.15) to the same transmitter for use in connection with the portable transmitter (key ring) of the encryption code firing method using radio waves. By adopting the same standard for use, the password of the coder is changed by changing the password, and the received user group (family) password is identified without manipulation due to the operation proximity recognition by the communication distance. It can make a doorbell sound to identify who is in the user's group (family) .In order to determine the user's entrance and exit status, the human body sensor is installed from the door to the inside to detect the reception status of the radio wave code code and detect the human body sensor. The logic of status enables the identification of the user's entry and exit, so that the doorbell is when the user is in or out of the house. By not sounding the same as the operation effect of the existing doorbell by operation,

If the user enters the outgoing communication phone number when the user goes out and operates the outgoing communication switch, the phone is dialed to the designated phone number by the pressed state of the doorbell switch, and if the call is not made, the call is made to the second designated phone number. When a call is made, a call is made between a visitor and an outgoing user by automatically connecting a phone and an interphone by matching a call, a call, a call, and a call of an interphone, and there is an electronic calendar and a clock installed inside the doorbell. If the user sets the date (birthday or anniversary), the melody (the melody corresponding to the anniversary), and the designated password (family), the specified password is received on the specified date and the specified melody is released when detected by the human body sensor inside the door.
