JP 2012-175661 A

  In the case of the intercom device disclosed in Patent Document 1, since the visitor video when the safety is confirmed is recorded, the resident can confirm the person who confirmed the safety later, and the resident is not worried. However, since the operation of the intercom device associated with the safety confirmation operation is maintained for about 45 seconds, for example, as long as the normal call operation, if a user wishes to continue the call operation, a waiting time occurs and the usability is poor. In addition, if a call operation is performed, a visitor image is displayed on the parent machine, but the resident cannot confirm who is confirming the safety during the safety confirmation.

  Therefore, in view of such a problem, the present invention completes the safety confirmation operation in a short time with respect to the duration of the calling operation, and when the safety confirmation is started, the visitor confirming the safety in the room master unit is selected. The object is to provide an intercom device that can be confirmed.

In order to solve the above-mentioned problems, the invention of claim 1 is directed to an entrance cordless handset provided with a function for a visitor to call a resident to make a call and a camera for imaging the visitor, and to call from the entrance cordless handset.

Residents stored in the department A notification control unit that notifies safety information to the entrance slave unit, and the duration of the notification operation when the safety confirmation button operation of the notification control unit is received is the duration of the call operation when the call operation is received from the entrance slave unit It is characterized by being less than or equal to one half of the above.
According to this configuration, since the operation time of the intercom device associated with the safety confirmation operation is as short as half or less than that of a normal call, a long waiting time does not occur when a call operation is performed thereafter, and the call operation is performed smoothly. And convenience is improved.

According to a second aspect of the present invention, in the configuration according to the first aspect, the living room master unit activates the camera in response to the safety confirmation button operation to display the captured image on the monitor and performs recording on the recording unit. A video control unit is provided.
According to this configuration, when the safety confirmation starts, the captured image of the entrance slave device camera is displayed in the room master unit, so that the resident can confirm the visitor who has confirmed the safety. Since recording is also performed at the same time, it can be confirmed later and saved as a history, which is useful for crime prevention.

According to a third aspect of the present invention, in the configuration according to the second aspect of the present invention, a display indicating that the safety is being confirmed is displayed on the video displayed on the monitor during the safety confirmation.
According to this configuration, it is possible to easily recognize that the video displayed on the living room base unit is a video accompanying the safety confirmation, and it is not mistaken for the visitor who has asked.

  According to the present invention, the operation time of the intercom device associated with the safety confirmation operation is as short as one-half or less than that of a normal call. And convenience is improved. When the safety confirmation starts, the captured image of the entrance slave camera is displayed in the room master, so that the resident can confirm the visitor confirming the safety.

It is a circuit block diagram which shows an example of the intercom apparatus which concerns on this invention. It is explanatory drawing of the monitor display image in safety confirmation.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 is a circuit block diagram showing an example of an intercom device according to the present invention, where 1 is an entrance handset for a visitor to call a resident and make a call, and 2 is a residence for a call from the entrance handset 1 This is a living room master for the person to respond, and both are connected by a transmission line L1. Also, 3 is a circumscribing button that is installed in a bedroom or the like and outputs a signal when pressed, 4 is a human sensor that is installed in a corridor or living room of a residence to detect the movement of a person, and 5 is installed on a door These are open / close sensors, which are connected to the room master unit 2.

  As shown in FIG. 1, the front door 1 has a camera 11 for imaging a visitor, a call unit 12 having a microphone and a speaker (not shown) for calling a resident, and a call button 13 for calling the resident. The LED 11 for illumination that enables the camera 11 to take a picture at night, the entrance slave unit IF 16 for communicating with the living room master unit 2, the slave unit control unit 17 for controlling each part of the entrance slave unit 1, and the like are provided. However, the call button 13 also serves as a safety confirmation button for confirming the safety of the resident, and the lighting LED 15 also serves as a notification unit for notifying the safety information of the resident.

The living room master unit 2 displays an image captured by the camera 11 of the front door unit 1 and displays a character information and the like, a call unit 22 having a microphone and a speaker (not shown) for calling a visitor, Video / history storage unit 23 for storing images captured by the camera 11 and safety history, operation unit 24 for performing various operations such as settings, general-purpose input unit 26 to which the external buttons 3 and various sensors are connected, for example, safety information such as 48 hours A first timer 27a that counts for generation, a second timer 27b that counts the operation time associated with the operation of the call button 13, a safety state storage unit 28 that stores a safety state, and a parent that communicates with the front door unit 1. A base unit control unit 30 that controls each unit of the machine IF 29 and the room base unit 2 is provided.
The operation unit 24 receives a call from the front door 1 and responds to the call button 24a. The occupant inputs a staying out button 24b that is operated when the resident stays out. For example, a safety button 24c is provided.

Next, the operation of the intercom apparatus configured as described above will be described. However, an operation in which a visitor operates the entrance cordless handset 1 to call a resident and makes a call, an operation in which the camera 11 is activated in response to the calling operation, and a captured image thereof is displayed on the monitor 21 of the room base unit 2. Since it is the same as that of the prior art, the description thereof will be omitted, and the safety confirmation operation will be mainly described here.
First, it is necessary to confirm that the safety state storage unit 28 of the living room base unit 2 does not receive a normal signal indicating that the resident is normal even though the resident is normal and the first timer 27a has counted up. Any one of the three states of the state and the overnight stay state in which the resident is absent due to the overnight stay is stored.

Now, description will be made assuming that the normal state is stored in the safety state storage unit 28. The change of the state stored in the safety state storage unit 28 and the control of the first timer 27a are performed by the parent device control unit 30. In a state where the safety state storage unit 28 stores the normal state, the first timer 27a operates to count a predetermined time (for example, 48 hours). If the first timer 27a counts up while the safety button 24c is not pressed during the counting, the human sensor 4 or the like does not operate, and there is no input to the general-purpose input unit 26, the safety state storage unit 28 is in a normal state. Is changed to a state requiring confirmation.
However, if the human sensor 4 or the open / close sensor 5 detects and inputs a signal to the general-purpose input unit 26 while the first timer 27a is counting, the first timer 27a is reset and counting is restarted.

  In accordance with the change to the confirmation required state, the confirmation of the confirmation required state is displayed on the monitor 21 of the living room master unit 2 by text information or the like, and for example, a message “Please press the safety button” from the speaker of the call unit 22. Is reported. In this manner, the resident who is in a normal state is urged to perform an input operation using the safety button 24c or the like by the display or the sound of sound. The notification operation is periodically performed until the safety button 24c is operated or a signal is input to the general-purpose input unit 26.

  When the safety button 24c is pressed by the resident or the circumscribing button 3 is operated in response to the warning sound or the like, the memory of the safety state storage unit 28 is changed to the normal state, and the notification operation ends. To do. The first timer 27a is reset and restarts counting for a predetermined time.

In addition, when the state of the safety state storage unit 28 is in a normal state or a state requiring confirmation, when the overnight stay button 24b of the living room master unit 2 is pressed, the storage in the safety state storage unit 28 shifts to the overnight stay state. At the same time, the first timer 27a is reset and starts counting for a predetermined time.
In this case, even if the first timer 27a counts up, the safety state storage unit 28 does not transition to the confirmation required state. When the occupancy button 24b is pressed by the resident who has returned home, the occupancy state is canceled, the storage in the safety state storage unit 28 becomes normal, and the first timer 27a starts counting. In this way, the normal state is stored in the safety state storage unit 28.

  In the intercom apparatus in which one of the three states is stored in the safety state storage unit 28 in this way, the call button 13 of the entrance cordless handset 1 is long pressed by a visitor who came to confirm the safety of the resident (for example, 2 When it is continuously pressed for a second), the handset controller 17 shifts to a safety confirmation mode, and a safety confirmation signal is output to the room master 2 in place of the normally output call signal.

Receiving the safety confirmation signal, the base unit control unit 30 reads the state of the safety state storage unit 28 and returns it to the front door unit 1. In addition, a display to the effect that the safety confirmation has been made is displayed on the monitor 21 of the living room master unit 2, and the camera 11 is driven to image a visitor who has come to confirm the safety and display the video on the monitor 21. At this time, the monitor 21 displays that the safety is being confirmed.
FIG. 2 is a display explanatory diagram of the monitor 21 at this time, and it can be seen that the visitor is a visitor for safety confirmation by the display M1 of “Marimori”. In the safety confirmation mode, there is no ringing tone in the room master unit 2. At the same time, recording is performed, and “recording in progress” M <b> 2 is displayed on the monitor 21.

  This recording is performed as a still image, and is stored in the video / history storage unit 23 together with confirmation history information including date and time information on which safety confirmation has been received. The stored image and history are displayed on the monitor 21 by the parent device control unit 30 by performing a predetermined display operation on the operation unit 24 of the living room parent device 2. For example, six still images are taken and stored within a predetermined time.

  On the other hand, in the entrance child device 1 that has received a reply from the living room parent device 2, the child device control unit 17 turns on / blinks the illumination LED 15 in accordance with the content of the reply signal. For example, if it is returned that it is in a normal state or an overnight stay state, blinking is performed once. The blinking state of the lighting LED 15 allows the visitor to confirm the safety state of the resident.

Here, the operation time of the intercom apparatus will be described. In the case of a normal call operation by the call button 13, a call signal is transmitted to the room base unit 2 when the call button 13 is pressed, and the following operation is performed by the base unit control unit 30 that has received the call signal.
The room master 2 reports the ringing tone and waits for the operation of the call button 24a (waits for response). This response waiting state is continued for a set time, and if the call button 24a is pressed during this time, a call path is formed and the resident can talk to the visitor. This duration is counted by the second timer 27b and is set to 45 seconds, for example.
In response to the call signal, the second timer 27b starts counting, and if there is no response operation before the set 45-second count ends, the master unit control unit 30 recognizes the end of the call and the response waiting state is Canceled. As a result, the call path is not formed even if the call button 24a is operated after returning to the standby state.

  On the other hand, in the safety confirmation mode, base unit control unit 30 starts counting the safety confirmation time set in second timer 27b. Here, the operation time in the case of safety confirmation is set to 15 seconds, and when the second timer 27b finishes counting for 15 seconds, the video display on the monitor 21 and the blinking operation of the illumination LED 15 are finished, and the interphone device Returns to the standby state.

As described above, the operation time of the intercom device associated with the safety confirmation operation is 15 seconds, which is extremely short compared to 45 seconds for a normal call. It is possible to shift to a call operation and the convenience is improved.
Moreover, since the captured image of the camera 11 of the entrance cordless handset 1 is displayed in the room master unit 2 when the safety confirmation starts, the resident can confirm the visitor confirming the safety. Since recording is also performed at the same time, it can be confirmed later and can be recorded as a history, which is useful for crime prevention.
Furthermore, the video displayed on the base unit 2 during the safety confirmation can be easily recognized that the video is being confirmed by displaying “Mimamori in”, and the visitor who asked There is no mistake.

In the above embodiment, the operation time for the safety confirmation is 15 seconds, but it may be 20 seconds or 10 seconds, which is as short as one-half or less of the call operation response waiting time. If you want to make a call after confirming safety, you can move to the call smoothly without a long waiting time. In addition, although the recording is a still image, a moving image (video) may be recorded.
Further, although “monitoring” is displayed on the monitor 21 during the safety confirmation, not only the display but also the “watching over” voice may be stored and reported from the call unit 22.
