BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a sensor-sensitive intercom system configured by combining a sensor-equipped intercom handset installed at a front door or the like and an intercom base unit installed indoors.
[0002]
[Prior art]
In recent intercom systems, a human sensor is built in the handset, and when this human sensor detects a person, lighting is turned on, or the sensor detection is sent to the indoor intercom master unit. There is something that sounds a notification sound.
[0003]
FIG. 10 is a diagram illustrating an example of this type of intercom system. Here, a camera intercom system is shown as an example.
[0004]
When the interphone master unit 100 receives a human detection signal from the sensor e built in the interphone slave unit 300, the interphone master unit 100 supplies power for operating the slave unit 300, and at the same time, detects that the slave unit 300 has sensed the sensor a or a. The speaker b informs by an image or sound.
[0005]
The intercom handset 300 outputs a camera d for picking up a person or the like when the sensor e senses, a microphone g for picking up a visitor's voice and surrounding sounds, and a sound from the base unit 100. The interphone base unit 100 includes a speaker f and the like. The interphone base unit 100 includes a monitor a for projecting an image captured by the camera d of the slave unit 300, a speaker b for outputting a notification sound, and a microphone c for talking to a visitor. Etc.
[0006]
This type of intercom system is equipped with a sensor that can detect people on the side of the handset, so that the householder can know the trap at the front door of a suspicious person, etc., from a warning sound or video while staying indoors. Yes, the crime prevention effect is extremely high. In addition, by linking an outdoor lighting device with sensor detection, there is also an effect that threatening a suspicious person and informing the surroundings can be performed.

[Problems to be solved by the invention]
However, in the conventional sensor-sensitive intercom system with such a configuration, every time the sensor is sensed on the handset side, a notification sound or video is output from the intercom master unit. There was also a problem that it worked.
[0010]
The present invention has been proposed to solve such a problem, and an object of the present invention is to provide a sensor-sensitive intercom system in which a user can freely set permission / prohibition of indoor notification by sensor detection.
[0011]
A second object is to provide an energy-saving sensor-sensitive intercom system that can reduce power consumption.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the sensor-sensitive intercom system according to claim 1 notifies the room that the sensor has sensed when receiving the interphone cord with the sensor and an activation signal from the sensor. This is a sensor-sensitive intercom system equipped with an interphone master unit that enables the following configuration.
[0013]
In other words, the interphone master unit is equipped with a sensor mode setting button that can switch whether to notify the sensor that the sensor has sensed when it receives a start signal from sensor detection, and whether to notify the sensor. The notification / non-notification mode is notified to the slave unit. The interphone slave unit with sensor is equipped with threatening means for emitting sound, light, etc., and at least when set to the non-notification mode, it outputs threatening when the sensor is sensitive.
[0014]
With this configuration, it is possible to easily permit / prohibit indoor notification at the time of sensor sensing, and as a result, when notification is not required, it is possible to prohibit the alarm sounding in the room and the light on the handset side. It is also possible to dissipate suspicious people by the intimidating output of sound.
[0015]
In the second aspect of the present invention, the interphone slave unit with sensor is supplied with operating power from the interphone master unit. When the interphone master unit receives the activation signal, the interphone master unit with the sensor notifies / notifies the interphone slave unit with sensor. The mode is notified by supplying operating power with different voltage values in correspondence with the non-notification mode.
[0016]
That is, the operating voltage of the supplied power that fluctuates serves as a mode notification means, and the intercom handset can perform an operation corresponding to the mode without sending a special mode signal.
[0017]
In the system according to the third aspect, the interphone slave unit with a sensor includes a camera, that is, forms a TV monitor intercom system. The interphone master unit supplies high voltage operating power for driving the camera in the notification mode, and supplies low voltage operating power for threatening output in the non-notification mode.
[0018]
According to a fourth aspect of the present invention, the interphone master unit intermittently supplies operating power, and ignores the activation signal for a certain period of time during the unpowered period.
[0019]
As a result, intermittent power supply to the interphone slave unit when the sensor sensitivity is frequent can be prevented, and as a result, a power saving effect can be improved and heat generation can be suppressed.
[0020]
The system according to claim 5 is configured such that an external device can be connected to the interphone slave unit with the sensor, and the interphone master unit has a load on the external device when the external device is connected to the interphone slave unit side. It is characterized by detecting a change in voltage due to an increase and determining the connection of an external device.
[0021]
According to a sixth aspect of the present invention, the intercom handset with sensor is configured to stop the power supply to the external device when the sensor is sensitive.
[0022]
That is, in claims 5 and 6, when an external device such as a sensor is connected to the handset side, the interphone base unit can determine the state of the handset by the voltage change of the interphone handset, It is possible to automatically change operations such as notification on the base unit side according to the state.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0024]
FIG. 1 is a diagram illustrating a configuration example of a sensor-sensitive intercom system. This intercom system is configured by connecting a sensor-equipped interphone slave unit 3 with a built-in sensor installed at a front door of an outdoor room and the like and an interphone master unit 1 with a monitor installed indoors by a transmission line L. Yes. In addition, although the system which can be monitored with a camera is shown here, it is not limited to this.
[0025]
The interphone slave unit 3 with a sensor of this system includes an imaging camera 39 for projecting an outdoor video on the base unit side, a microphone 40 for calling, a speaker 38, a built-in human sensor 41, and a suspicious person. A threatening light source (LED) 37 is provided, and the interphone master unit 1 includes a monitor TV 19 that displays outdoor video, a microphone 20 for calling, a speaker 18, and a sensor mode setting button for setting a notification / non-notification mode. 12 etc. are provided.
[0026]
In this intercom system, video signals and mutual audio signals captured by the camera 39 are transmitted between the master unit 1 and the slave unit 3 via the transmission line L, and the master unit 1 is used for driving the camera 39 and the like. Operating power is supplied to the slave unit 3.
[0027]
This system includes an intercom function for talking to a visitor while sending and receiving audio signals via a transmission line L, a camera monitoring function for monitoring a visitor by transmitting a camera video signal to the parent device side, and a human sensor 41. It has basic functions such as a crime prevention function that transmits a start signal to the base unit side when it detects a suspicious person or the like to sound a notification sound.
[0028]
In particular, according to the present invention, if the user operates the sensor mode setting button 12 of the intercom base unit 1, when the human sensor 41 on the side of the handset 3 senses, the base unit 1 notifies the user with sound or video. You can set whether to do it. That is, the button 12 is an operation means that enables the sensor 41 to switch between the notification mode and the non-notification mode.
[0029]
In this way, in the system of the present invention, the indoor notification at the time of sensor sensing can be permitted / prohibited by user operation. Therefore, when the user needs sensor notification for crime prevention, the user sets the notification mode, thereby It is possible to know the trap at the front of the suspicious person with a notification sound, etc., but on the other hand, when the notification sound is unnecessary, set it to the non-notification mode, so that the notification sound does not sound even if the sensor responds. In addition, the threatening light source 37 provided in the child unit 3 can be turned on and blinked to dissipate the suspicious person. As another threatening means, a loud sound may be generated from the speaker 38. Further, threatening output may be performed even in the notification mode.
[0030]
2 to 4 are block diagrams showing the main configuration of the sensor-sensitive intercom system. 2 shows the overall configuration of the system, FIG. 3 shows the interphone slave unit 3 with a sensor, and FIG. 4 shows the internal configuration of the interphone master unit 1.
[0031]
The interphone slave unit with sensor 3 includes a slave unit control unit 31 composed of a microcomputer for controlling the following units, a startup signal generation unit 32 that causes the master unit 1 to generate a startup signal upon sensor detection, and the voltage of the slave unit. A voltage detection unit 33 for detecting, an audio receiving unit 34 for receiving audio from the main unit 1, a video / audio transmitting unit 35 for transmitting camera video and audio, and a battery unit or power supplied from the main unit 1 by the camera unit 39 A power supply unit 36 for supplying power to the light source unit 37, a threatening light source unit 37 composed of LEDs, a speaker unit 38, a camera unit 39, a microphone unit 40, a sensor unit 41 composed of a human sensor, etc. FIG. 3).
[0032]
On the other hand, the interphone base unit 1 includes a base unit control unit 11 that controls each unit, the above-described sensor mode setting button unit 12, a handset power supply unit 13 that supplies operating power to the interphone handset 3, and the handset 3. The child device activation signal detector 14 for receiving the activation signal, the child device voltage detector 15 for detecting a voltage change for monitoring the state of the child device 3, the video / audio receiver 16 for receiving the camera image and the sound, 4 is provided with a sound transmitting unit 17 for transmitting sound from the microphone, a speaker unit 18, a monitor unit 19 composed of a liquid crystal, a CRT, and the like (FIG. 4).
[0033]
The intercom master unit 1 and the interphone slave unit 3 with the sensor are connected via a transmission line L that is a paired line, and power and video signals are transmitted through the transmission line L by both multiplexing circuit units (not shown). Audio signals and the like are multiplexed and transmitted. The transmission line L is not limited to a pair line.
[0034]
In such a configuration, when the human sensor 41 of the interphone slave unit with sensor 3 detects a person, the slave unit control unit 31 detects a sensor signal, transmits the control signal to the activation signal generation unit 32, and generates the activation signal. Unit 32 sends an activation signal to intercom base unit 1.
[0035]
In the intercom base unit 1, when this activation signal is detected, the base unit control unit 11 outputs a control signal to the microphone unit 20, the monitor unit 19, and the speaker unit 18 to perform a notification operation and also to the handset power supply unit 13. On the other hand, power supply to the intercom slave 3 is started.
[0036]
When the sensor mode setting button 12 of the intercom base unit 1 is operated, the base unit control unit 11 switches between the sensor mode notification mode and the non-notification mode.
[0037]
In order to notify the sensor-equipped intercom handset 3 that the sensor mode has been switched, in the present invention, power is supplied by changing the voltage of the power supplied to the handset when receiving the activation signal. The voltage detector 33 detects the voltage value to detect either the notification or non-notification mode.
[0038]
Thus, since the mode state is notified by the voltage value, the interphone slave unit 3 with the sensor can perform different operations depending on the voltage value. Moreover, since the intercom base unit 1 only needs to change the power, it is not necessary to send a special mode signal.
[0039]
Note that the notification of the setting mode is not limited to that by a change in voltage value, and a mode signal may be transmitted when a button is operated.
[0040]
In response to the notification of the setting mode, the intercom handset 3 starts the imaging by driving the camera 39 in the notification mode, and executes an operation of sending the video signal to the parent device side. If there is, light and sound are output from the LED 37 and the speaker 38 which are threatening means.
[0041]
FIG. 5 is a diagram illustrating a waveform example of the power supply voltage of the interphone slave unit 3.
[0042]
As described above, it is necessary to drive the camera 39 of the intercom handset 3 in the notification mode. On the other hand, in the non-notification mode, it is not necessary to drive the camera 39 because there is no need to send an image to the base unit.
[0043]
Therefore, there is a difference in the required operating power in the notification / non-notification mode. Therefore, for example, as shown in FIG. 5, when the interphone master unit 1 receives the activation signal from the slave unit 3, The power supply voltage (1) during operation and the power supply voltage (2) during operation may be different from those in the non-notification mode.
[0044]
The intercom handset 3 that has received the supply of operating power can detect the voltage value to detect the mode, and operate devices such as the camera 39 and the threatening light source 37 according to the mode.
[0045]
In the method of always supplying power when the sensor 41 is sensed as described above, if the human sensor 41 is frequently sensed, the power supply to the intercom handset 3 continues intermittently for a long time. There is a risk that problems such as an increase in
[0046]
FIG. 6 is a voltage waveform diagram for explaining another example of the power feeding method from the intercom base unit 1, and this power feeding method prevents intermittent power feeding.
[0047]
As shown in FIG. 6, the intercom base unit 1 is provided with a time zone T <b> 1 in which power is supplied to the slave unit and a time zone T <b> 3 in which power is not supplied to the slave unit so that operating power is intermittently supplied from the slave unit power supply unit 13. In the unpowered time T3, a time zone T2 for ignoring the activation signal from the slave unit is provided within that time, and no power is supplied even if the activation signal due to the sensor response is received. During the time period other than the activation signal ignoring time T2, the reception of the activation signal is allowed, and voltage supply according to the notification or non-notification mode is performed.
[0048]
For example, if the power feeding time T1 and the activation signal ignoring time T2 are each set to about several seconds, when the activation signal is sent from the interphone slave unit with sensor 3 in the non-notification mode, power is supplied for several seconds. The intercom unit 3 is intimidating with light, sound, etc., and the power supply is forcibly stopped during the period from the elapse of the power supply time T1 to the non-power supply time T3, and for a few seconds T2 from the elapse of the power supply time T1 The activation signal is ignored and the activation signal is accepted after the activation signal ignoring time T2.
[0049]
Similarly, intermittent power supply is performed in the notification mode. However, when monitoring by camera imaging is desired to be performed longer than the above-described power supply time T1, different power supply times or not yet different for the notification / non-notification mode. You may enable it to set power supply time and starting signal neglect time.
[0050]
If intermittent power supply is performed in this way, it is possible to improve power saving and heat generation suppression effects while having functions such as camera monitoring and threatening output.
[0051]
FIG. 7 is a diagram illustrating another configuration example of the sensor-sensitive intercom system.
[0052]
In this intercom system, an external device 5 such as a lighting fixture, a speaker, and other sensors is connected to an interphone slave unit 3 with a sensor. In addition, since the structure of the interphone subunit | mobile_unit 3 with a sensor and the interphone main | base station 1 is the same as FIG. 1, description of each code | symbol is omitted.
[0053]
For example, if the external device 5 to be connected is a luminaire, the lighting may be blinked in conjunction with sensor detection for threats in the non-notification mode. May be notified.
[0054]
The intercom base unit 1 detects that the external device 5 is connected by a voltage change. That is, as shown in FIG. 8, when another external device 5 is connected to the interphone slave unit 3 with the sensor, the load increases, so that the voltage during standby or operation drops, and the interphone master unit 1 Then, this voltage fluctuation amount is detected by the handset voltage detector 15 (FIG. 1), and it is determined that the external device 5 is connected. This will be described more specifically.
[0055]
When the rain sensor 5 is connected to the interphone slave unit 3 with the sensor, the interphone master unit 1 detects that the standby voltage has dropped from the standby voltage (1) to the standby voltage (2). It detects that the rain sensor 5 is connected.
[0056]
Next, in the interphone slave unit 3 with the sensor, when the human sensor 41 senses, the power supply from the interphone slave unit 3 to the rain sensor 5 is stopped, and the state is the same as when the external device 5 is not connected. To do. That is, the operating voltage at this time is the operating voltage (1). The intercom base unit 1 detects this operating voltage (1).
[0057]
On the other hand, when the rain sensor 5 is operated, the load increases due to the sensor operation. Therefore, even if the same power supply is performed from the interphone master unit 1, the operating voltage of the interphone slave unit 3 is in the operating voltage (2) state.
[0058]
With such a configuration, the intercom base unit 1 sounds a notification sound when it detects the operating voltage (1) to notify the suspicious person's habit, and when it detects the operating voltage (2), the interphone master unit 1 rains with a different notification sound. Can be informed.
[0059]
FIG. 9 shows a schematic operation flowchart on the base unit side when the external device 5 is a rain sensor.
[0060]
As described above, since the interphone master unit 1 monitors the fluctuating operating voltage, even when the external device 5 is connected to the slave unit side, the operation such as notification can be automatically changed.
[0061]
In this example, two operating voltages in the notification mode (voltages during operation (1) and (2)) are detected. However, in the non-notification mode, the variation in the operating voltage can be detected, A plurality of types of operations may be automatically performed.
[0062]

Can be raised. Moreover, heat generation can be suppressed.
[0066]
In claim 5, when an external device such as a sensor is connected to the interphone slave, the interphone master detects the voltage change of the interphone slave and determines the connection of the device. The state can be automatically recognized and an operation suitable for the state can be performed.
