I have.
[0019]
Hereinafter, the operation of the TV door phone device configured as described above will be described.
The resident presses the call button 102 of the TV door phone 1 twice within an arbitrary time to enter a password for unlocking the electric lock of the door 3 outside the house (outdoor) when returning home or the like. As a result, the CPU 109 determines that the personal identification number is in the input state, so that the light 105 is turned on under the control of the CPU 109, the wide-angle lens 107 is mechanically selected by the lens control circuit 113, and the CPU 109 The television camera 103 starts operating in response to the activation signal. Further, data for notifying that the personal identification number is in the input state is output from the CPU 109, and the data is transmitted via the data transmission / reception circuit 110, the multiplexing / demultiplexing circuit 114, the multiplexing / demultiplexing circuit 211 of the television intercom base unit 2, and the data transmitting / receiving circuit 206. Then, the data is sent to the CPU 205 of the television intercom master device 2, and the CPU 205 that has detected the input of the data activates the position recognition circuit 210.
[0020]
Here, when the resident presses a pixel position of an arbitrary number (0 to 9) constituting the password input unit 101 of the TV door phone 1 with a finger, a luminance signal is included from the TV camera 103 via the wide-angle lens 107. The video signal is output and sent to the position recognition circuit 210 via the modulation circuit 106, the multiplexing / demultiplexing circuit 114, the multiplexing / demultiplexing circuit 211 of the television intercom master 2, and the demodulation circuit 208. The position recognizing circuit 210, which has received the video signal containing the luminance signal, recognizes and stores which pixel number has been pressed, and then outputs a signal indicating that recognition of the first character of the password has been completed to the CPU 205. Output to Further, the CPU 205 sends the signal to the CPU 109 via the data transmission / reception circuit 206, the multiplexing / demultiplexing circuit 211, the multiplexing / demultiplexing circuit 114 of the TV intercom 1, and the data transmitting / receiving circuit 110, thereby detecting the above-described signal. The CPU 109 sounds the sounder 111 to notify the visitor or the like to press the next digit number (password) using the password input unit 101.
[0021]
After repeating the above-described operation of inputting the personal identification number by the number of digits of the personal identification number, the position recognition circuit 210 of the television intercom base unit 2 checks the data of the personal identification number set by the personal identification number setting circuit 204 with the stored data. And outputs the result data to the CPU 205. The CPU 205 sends the result data to the CPU 109 via the data transmission / reception circuit 206, the multiplexing / demultiplexing circuit 211, the multiplexing / demultiplexing circuit 114 of the TV intercom 1, and the data transmitting / receiving circuit 110. By sounding the sounder 111, the visitor or the like is notified by sound (voice) whether or not the door 3 can be unlocked. At the same time, when the result from the position recognition circuit 210 matches, the CPU 205 that has transmitted the above-described result data outputs an electric lock release signal via the electric lock interface 207 and outputs the electric lock signal of the door 3. By controlling the driving unit 301, the electric lock is unlocked. Further, when the resident using the TV intercom master unit 2 presses the electric lock release button 202, the CPU 205 determines that the electric lock is unlocked and outputs an electric lock release signal via the electric lock interface 207. Therefore, the electric lock driving unit 301 of the door 3 is controlled, the electric lock is unlocked, and the electric lock of the door is unlocked by the input operation of the personal identification number.
[0022]
Next, when a visitor or the like presses the call button 102 of the TV door phone 1 once within an arbitrary time in order to call a resident using the TV intercom master unit 2 outside the house (outdoor), the CPU 109 makes this call. Since the state is determined, the lens control circuit 113 mechanically selects the standard lens 108 under the control of the CPU 109, and the television camera 103 starts operating in response to an activation signal from the CPU 109. Further, data for notifying the calling state is output from the CPU 109, and the data is transmitted through the data transmission / reception circuit 110, the multiplexing / demultiplexing circuit 114, the multiplexing / demultiplexing circuit 211 of the television intercom master unit 2, and the data transmitting / receiving circuit 206. The CPU 205 of the intercom master unit 2 which has transmitted the data and detected this data activates the monitor 201. Therefore, the video signal which is a video of a visitor or the like taken by the television camera 103 of the television door phone 1 is modulated. The signal is transmitted to the monitor 201 via the circuit 106, the multiplexing / demultiplexing circuit 114, the multiplexing / demultiplexing circuit 211 of the television intercom master unit 2, and the demodulation circuit 208, and is displayed and reproduced on the monitor 201.
[0023]
Here, when the resident using the TV intercom master 2 performs a response operation such as picking up the handset 203 from the TV intercom master 2 and goes off-hook (not shown), an off-hook signal is output from the handset 203 to the CPU 205. Is done. The CPU 205 that has detected the input of the off-hook signal activates the audio circuit 209 and sends the off-hook data to the CPU 109 via the data transmitting / receiving circuit 206, the multiplexing / demultiplexing circuit 211, the multiplexing / demultiplexing circuit 114 of the TV intercom 1, and the data transmitting / receiving circuit 110. The CPU 109 that has detected the input of the off-hook data activates the audio circuit 112 from the transmission. Therefore, the audio signal input from the microphone 203 b forming the handset 203 of the TV intercom master unit 2 is input via the audio circuit 209, the multiplexing / demultiplexing circuit 211, the multiplexing / demultiplexing circuit 114 of the TV door phone 1, and the audio circuit 112. The audio signal output from the speaker 104a forming the output unit 104 and similarly input from the microphone 104b forming the audio input / output unit 104 of the TV intercom 1 is converted into an audio circuit 112, a multiplexing / demultiplexing circuit 114, and the TV intercom master unit 2. Of the handset 203 via the multiplexing / demultiplexing circuit 211 and the audio circuit 209 of FIG.
[0024]
Further, after the simultaneous call, the resident using the TV intercom base unit 2 hooks the handset 203 on the TV intercom base unit 2 (not shown), so that an on-hook signal is output from the handset 203 to the CPU 205. The CPU 205 that has detected the input of the on-hook signal puts the monitor 201 and the audio circuit 209 in a standby state, and transmits the on-hook data to the data transmitting / receiving circuit 206, the multiplexing / demultiplexing circuit 211, the multiplexing / demultiplexing circuit 114 of the TV door phone 1, the data Since the data is transmitted to the CPU 109 via the transmission / reception circuit 110, the CPU 109 that has detected the input of the on-hook data sets the television camera 103 and the audio circuit 112 in a standby state.
[0025]
【The invention's effect】
As is apparent from the above description, according to the TV door phone apparatus according to the present invention, the TV door phone installed at the entrance of the dwelling unit is configured as a data input terminal. Since there is no need to provide a password input unit (input device), the degree of freedom in designing the entrance to the dwelling unit is improved, and a camera (TV camera) having a video shooting function is built into the TV door phone. Since it is difficult for a visitor or the like to discriminate, the visitor or the like can stand in front of the TV door phone without being shunned, and security is improved.
