Description

  The present invention relates to a housing information panel and information equipment, and more particularly to power saving of the monitor.

In an apartment house such as an apartment, a collective entrance machine is provided at the collective entrance, and an entrance cordless handset (door phone) is provided at the entrance of the dwelling unit. These entrance machines (collective entrance machine / entrance child machine) have a built-in camera, and when calling, the video of the visitor is displayed on the monitor of the housing information panel installed in the dwelling unit ( For example, Patent Document 1). The monitor of the home information panel is not normally lit, but is lit when necessary, such as calling from the front door, and displays video, character information, and the like. In this way, the power consumption of the monitor is reduced by normally turning off the monitor.
Japanese Patent Laid-Open No. 10-150499

  However, at the time of calling, etc., regardless of whether there is a person checking the monitor on the house information board side, the monitor is uniformly activated and turned on, and the power saving of the monitor has not been sufficient. This also applies to information devices that display the signal reception by turning on the monitor or displaying characters when a signal is received from a device connected via a network or the like. There was a problem that it was not enough.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a housing information panel and an information device in which power consumption of the monitor is further thoroughly reduced.

The housing information board according to the present invention is a housing information board having a monitor for displaying a video signal from the camera when a call is made from an entrance machine having a camera. And a control unit that controls the monitor not to be lit when the human sensor does not output a detection signal when a call is made from the entrance machine. It is a thing.
In addition, the housing information panel according to the present invention is operated when the user goes out in a housing information panel having a monitor that displays a video signal from the camera when called from an entrance machine having a camera. A security switch to be set to a monitoring mode, and a control unit that controls the monitor not to be lit when the crime prevention switch is on when a call is made from the entrance machine. It is provided.
The information device according to the present invention is an information device that turns on a monitor or displays characters to indicate that a signal has been received by receiving a signal from a device connected via a signal line. A human sensor that detects whether or not there is a person in the surroundings, and a control unit that controls the monitor not to light up when the human sensor does not output a detection signal when the signal is received. It is a thing.

  In the present invention, when a call is made from the entrance machine (or when a signal is received from the above-mentioned device), the human sensor is monitored when there is a person around the housing information board (or information device). Start up to display or turn on video, but if there are no people around the housing information board (or information equipment), you can see it even if the monitor is turned on and turned on Since there is no person, the light is not turned on (light-off state), thereby reducing the power consumption of the monitor, and accordingly, the life of the monitor can be extended. Further, when the crime prevention switch is turned on, the same processing is performed, so that the power saving and long life of the monitor can be achieved.

  FIG. 1 is a block diagram showing a configuration of an intercom system according to an embodiment of the present invention, and FIG. 2 is a block diagram showing details of the house information board. The intercom system shown in FIG. 1 includes a collective entrance machine 10, a manager room parent machine 20, a call control device 30, and a house information board 40. The collective entrance machine 10, the manager room master machine 20, and the house information board 40 can communicate with each other via the call control device 30. The collective entrance machine 10 has a built-in camera 11 for photographing a visitor and transmitting a video signal thereof to the home information board 40 of the visited site via the call control device 30. A door phone 50 is connected to the house information board 40, and a camera 51 is built in the door phone 50. The house information board 40 is attached inside the dwelling unit, the doorphone 50 is attached outside the entrance of the dwelling unit, and the camera 51 of the doorphone 50 outputs a video signal to the house information board 40 when a visitor is photographed. Although FIG. 1 shows a state in which each device is connected by the communication line T, each device is not only used for the communication line T but also for the video signal line and the transmission control line. It is connected to the.

  2 includes a calling unit 41, a video signal receiving unit 42, a call detecting unit 43, a control unit 44, an alarm unit 45, an operation unit 46, a human sensor 47, an activation circuit (lighting circuit) 48, and a monitor. 49. The human sensor 47 is configured to detect a temperature change when an object having a temperature difference from the ambient temperature moves within the detection area using infrared rays, and detects a human movement. A sensor that detects the movement of a person or object in the sensing area and sends a detection signal. The human sensor 47 is attached at a position where it can be detected whether or not there is a person around the house information board 40, and may be built in the house information board 40.

  2, for example, when a call button (not shown) of the door phone 50 is operated, the call detection unit 43 detects the call and outputs the call to the control unit 44. 45 is driven to output a ringing sound (for example, chime sound) from the alarm unit 45 in order to notify that a visitor is coming, for example. Thereby, the resident can recognize that the visitor is coming to the entrance when he is in the room. At this time, in the door phone 50, the camera 51 images a visitor and transmits the video signal to the house information board 40. When the call detection unit 43 detects the call, the control unit 44 takes the video signal into the video signal reception unit 42 and causes the control unit 44 to output the video signal. At this time, the control unit 44 determines whether or not the human sensor 47 outputs a detection signal. If not, the control unit 44 does not drive the activation circuit 48 and keeps it as it is. That is, control is performed so that the video signal is not displayed on the monitor 49 without turning on the monitor 49 (maintaining the light-off state) even though the video signal from the camera 51 is received. When there is no resident in the vicinity of the house information board 40, it is meaningless to display an image on the monitor 49. Thus, power is saved without turning on the monitor 49 in this way. When there is a resident in the vicinity of the house information board 40 and a detection signal from the human sensor 47 is input, the control unit 44 drives the activation circuit 48 and the activation circuit 48 activates the monitor 49. The video based on the video signal is displayed. When the resident wants to make a call with the visitor after confirming the visitor displayed on the monitor 49, for example, the line with the door phone 50 is established by picking up the call unit 41 composed of a handset or the like. Connected and ready to talk.

  Further, a call is made to the housing information board 40 from the collective entrance machine 10 via the call control device 30 and a control line (not shown), and the housing information is transmitted from the camera 11 of the collective entrance machine 10 via the call control device 30 and a control line (not shown). When a video signal is transmitted to the panel 40, the same processing is performed. When the detection signal from the human sensor 47 is input, the control unit 44 drives the start circuit 48, and the start circuit 48 The monitor 49 is activated to display an image based on the image signal. When the detection signal from the human sensor 47 is not input, the monitor 49 is not turned on (maintains the unlit state), and the image signal is displayed. Is not displayed on the monitor 49.

  Further, when calling the house information panel 40 via the call control device 30 and the call line T, the manager room master unit 20 drives the alarm unit 45 to sound a ringing tone and turn on the monitor 49 or In some cases, the character information is displayed to inform the resident that the call is from the administrator room master unit 20, but even in such a case, the control unit 44 causes the human sensor 47 to output a detection signal. If there is, the control unit 44 drives the starting circuit (lighting circuit) 48 to turn on the monitor 49 or display character information, but when the human sensor 47 does not output a detection signal, Control is performed so that the monitor 49 is not lit.

  In addition, although said embodiment is an example of an intercom system, it is applied similarly, for example in information equipment, such as a personal computer. In such a case, for example, in an information device that displays a signal reception by turning on the monitor or displaying characters when a predetermined signal is received from another device connected to the network, the predetermined signal is received from the other device. If the human sensor does not output a detection signal when the signal is received (that is, if there is no person around the information device), the monitor is not turned on and the human sensor outputs a detection signal. If so, the monitor is turned on or a character is displayed to indicate that the signal has been received.

  By the way, the house information board 40 is usually provided with a switch for crime prevention. When this switch is operated when going out, etc., the inside of the dwelling unit is set in the monitoring mode and provided for a thief or the like. Therefore, this crime prevention switch may be used in place of the human sensor 47. That is, when this crime prevention switch is on, the resident is out and not in the dwelling unit, so there is no need to light the monitor. Therefore, the control unit 44 may perform control so that the monitor 49 is not turned on when the crime prevention switch is turned on when a call is made from the entrance machine. Note that when the crime prevention switch is turned on, power may be saved so that the human sensor 47 is turned off. However, in this case, since the human sensor for crime prevention is in the monitoring mode, power is supplied.

It is a block diagram which shows the structure of the intercom system which concerns on embodiment of this invention. It is the block diagram which showed the detail of the housing information board of FIG.
