DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a videophone device with a security function.

[0002]

2. Description of the Related Art In recent years, various security systems have been devised which can monitor the situation of a remote place using a telephone line. These are composed of a slave unit having a CCD camera and a sensor, and a master unit having a monitor.

[0003] When the sensor of the slave unit detects an intruder or an abnormal condition, the CCD camera starts to operate, and a telephone is connected to the master unit by the auto dial function, and the image of the state of the room and the like taken by the CCD camera of the slave unit. Can be sent to the master unit at a remote location and displayed on the monitor of the master unit.

[0004] An administrator or the like who looks at the monitor of the parent machine calls the police or a resident in the neighborhood to request treatment for an abnormal situation. In these security devices, the roles and functions of the parent device and the child device are limited, and no role other than checking the place where the child device is installed on the monitor of the parent device can be performed. Some devices have a plurality of master units and slave units. However, each master unit can only monitor a plurality of slave units, and cannot monitor the master unit from the slave units. That is, limited to one-way monitoring,
In order to perform two-way monitoring, it was necessary to purchase two sets of security systems and install a master unit and a slave unit on both sides.

[0005] Also, assuming that a contact is out of the office, a plurality of master units are registered, and a plurality of telephone numbers of the master unit of the contact are registered. In some cases, the call to the next-ranking parent device will automatically be made again if not. However, in the contact with the parent device,
Even if a person who does not understand the operation of the device or the meaning of the monitoring information, such as a child, elderly person, or sick person, picks up the handset, confirms that the handset is connected to the base unit and continues communication with the base unit. It will be. However, in this case, since the person handling the parent machine does not understand the meaning of the monitoring information or does not know the operation of the device, it is difficult to see / hear this monitoring information to accurately determine a notification or to operate the device. is there.

In addition, since there is no communication at all with the master unit that is to be contacted in the next order, the person having the master unit in the next order cannot know even the occurrence of an abnormal situation.
The transmitted monitoring information may be wasted.

[0007]

Therefore, the present invention can be used not only as a security system that can be monitored in both directions, but also as a videophone, and a person who can respond to a contact when making a call with an automatic dial in an emergency. If not, it is an object to provide a videophone device with a security function capable of making a call back to the next contact.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to preferred embodiments. [Embodiment] FIG. 1 is a diagram showing a monitoring apparatus used in this embodiment. In the figure, (1) is a main body of the monitoring device, (1a) is an upper cover of the main body, and (2) is a head portion. The head (2) is the main body (1)
When detached from the main body, the user can press the cover open button (1b) of the main body (1) to open the upper cover (1a) and take it out.

FIG. 2 is a view showing the head section (2) separated from the main body (1), (3) is a CCD camera, (4) is a sensor, and (5) is a microphone. In this embodiment, the sensor (4)
As an infrared sensor was used. Also, CCD camera
(3) uses a color of 350,000 pixels in consideration of transfer speed and display on a monitor.

(6) is a wiring connecting the head part (2) and the main body (1). In this embodiment, the head part (2) and the main body
Although (1) is connected by wire, it may be connected by wireless.

When the sensor (4) detects an abnormal situation such as an intruder after starting the alert mode, the CCD camera (3) and the microphone (5) start operating. While the alert mode is started, the sensor (4) is always in operation, but the power of the CCD camera (3) and microphone (5) is usually turned off to save energy.
In this state, the power is turned on when the sensor (4) detects.

The main body (1) receiving the detection signal from the sensor (4)
Calls a pre-registered contact by auto dial, displays the image from the CCD camera (3) on the monitor of the monitoring device installed at the contact, and displays the speaker (17).
The sound from the microphone (5) can be played.

In the videophone device with a security function of the present invention, two or three or more monitoring devices form a group, but each monitoring device is an equivalent device having no parent-child relationship. for that reason,
Members of the group can perform two-way emergency monitoring.

[0038] Usually, it can be used as a videophone in a group. Unlike the case where the sensor detects and communicates, the user uses the telephone (8) connected to the main unit (1) to make a telephone call like a normal telephone and talk with the other party while looking at the face Can be. At this time, if the head (2) is separated from the main body (1), a call can be made even at a position distant from the front of the monitoring device.

Even if the other party does not answer the telephone, the other party operates the monitoring device by sending the ID by himself / herself to see and hear the image of the CCD camera of the other party, the sound from the microphone, and various settings. It can be performed. As a result, it is possible to check whether there is any abnormality by calling the house where the person is away or the bedridden elderly person or the child's house.

A person having a monitoring device can belong to a plurality of small groups having the same monitoring device and can use each other as mutual monitoring and as a videophone in each small group.
FIG. 6 is a diagram illustrating a small group. In the figure, X and Y are small groups, respectively. x ₁ and x ₂ are members of the small group X, and y ₁ and y ₂ are members of the small group Y. I is a member belonging to both the small group X and the small group Y.

I can perform mutual monitoring and videophone calls with members of any small group.
For example, since x ₁ does not belong to the small group Y, x ₂
And I can be mutually monitored, but cannot be mutually monitored with y ₁ and y ₂ . Similarly, y ₁ cannot be mutually monitored with x ₁ and x ₂ . That is, members of different small groups cannot perform mutual monitoring or videophone calls between them.

The monitoring device registers the small ID of each small group in addition to the ID serving as the reciting number of the group for which mutual monitoring is to be performed so that each small group can be recognized. I cannot do it. The small ID is set for the small group mainly because privacy issues are considered.

For example, if I in FIG. 6 is oneself, small group X is a small group of relatives, and small group Y is a small group related to business, privacy is high if business personnel can monitor relatives. It can be a breach, on the other hand, allowing relatives to monitor business personnel, which can lead to privacy breaches and trade secret leaks. If I has one monitoring device, I can perform mutual monitoring with any small group.

The setting of the small ID is an optional action, and if there is only one small group, the small ID may be left blank without setting it. If the small ID is not set, the collation of the small ID is omitted at the time of connection.

Hereinafter, the present invention will be described in more detail.

FIG. 3 is a schematic diagram showing the connection between the monitoring apparatus of this embodiment and peripheral devices. It should be noted that power supply lines between the devices are omitted for ease of explanation.

The wiring (6) of the head section is composed of image wiring (6a),
It has an audio wiring (6b) and a sensor wiring (6c), and is connected to the CCD camera (3), microphone (5), and sensor (4) of the head (2), respectively.

(1c) is a modem section of the main body, which is connected to a telephone line (external line) (7a) and to a telephone (8) via a connection line (7b).

(9) is a switch panel for switching between “start” and “cancel” of the alert mode, which may be provided integrally with the main body (1) or provided separately as shown in FIG. You may connect with 1).

The switching between "start" and "cancel" of the alert mode is performed by switching of the monitoring device body (1) or the switch panel (9), and these can be directly switched by hand. Wireless remote control
Providing (10) improves the practicality.

As the wireless remote controller (10), an infrared remote controller is suitable, but other types, for example, a weak FM
It may be a transmission type. In the embodiment, the wireless remote controller itself is used as a key ring so that the key is not easily lost.

When the alert mode can be switched by the wireless remote controller (10), the switch panel
(9) can be installed in hard-to-reach places. This prevents the alert mode from being unexpectedly switched due to mischief or the like.

Note that the mode in which the alert switch is switched after a lapse of a predetermined time after switching is enabled. The reason for the delay of a certain time is that the sensor itself is detected by the sensor in a short time of about 1 to 2 minutes until the caution "starts" and then leaves the room or after entering the room and "releases" This is to prevent that.

Here, when the wireless remote controller (10) is used to send an instruction from outside to the light receiving section (9a) of the main body or the switch panel (9) through the window to switch the mode, the room exits within a predetermined time. It is convenient because there is no need to pan or switch.

By the way, from a security problem,
Because the wireless remote control (10) is managed by the responsible person,
The person in charge will go to work earlier than any of the employees and will not be able to return until all employees have returned home.

Further, there is a case where the employee needs to enter the room after returning to the home after setting the alert mode to "start", for example, when the employee returns to get a lost item, or can urgently use it on a holiday or at night. Even in that case, since the person other than the responsible person does not have the wireless remote control (10), it is necessary to call the administrator and have the warning mode “cancel”, which is inconvenient.

In such a state, the manager becomes unnecessarily long working hours and does not know when to call when returning home, so he cannot calm down.

Therefore, in the present invention, the "start" and "cancel" of the alert mode can be switched by telephone through a telephone line.

According to this, when the person in charge is not present at the site, the employee who tries to enter the room calls the manager's home phone or mobile phone, asks the manager to call the alarm device, and sets the alert mode. Can be canceled. The administrator only needs to input an ID (pass number) for allowing the device to recognize that the administrator is a legitimate administrator, and also input a command to set the alert mode to "cancel". All of the ID and mode switching commands can be performed by a telephone push button. When the administrator makes a telephone call from the monitoring device, the ID is automatically checked. Therefore, the administrator does not need to press the ID himself, and only needs to send the mode switching command.

Similarly, an employee who has remained in the room until the end due to overtime or the like can call the manager when returning home and have the alert mode switched to “start”. Therefore, the person in charge does not need to be at the site just for mode switching.

(11) is a notification button (nurse call) connected to the position of the monitoring device main body. When the bedridden elderly person, the answering machine child or the like presses the emergency communication switch in the event of poor physical condition or an emergency, the monitoring device detects the sensor. (4) is in the same state as when the abnormality was detected, the CCD camera (3) starts operating, and the contact is dialed automatically. Thus, the contact can be notified of the abnormal state.

Even in a case where the user cannot get up because of illness, if the head unit (2) is installed nearby, it is possible to make a hands-free call in a state where the handset is not picked up and lying down, and the other party can contact the user. The status can be known by looking at the appearance displayed on the monitor of the monitoring device.

(12) is a sensor unit.
Although one sensor unit (12) is connected to the main body (1) by wire, the number of sensor units (12) is not limited to this, and a wireless connection may be used. The sensor unit (12) has a CCD camera (12a) and a sensor (12b), and can be arranged at a position different from the head unit (2) to enable monitoring in a wide range. For example, it can be considered to be installed in a garage, a back door, or near a window.

Even in the case where the head unit (2) is arranged in the same room, since the installation angle is different if the installation location is different, it is possible to check the situation from another angle. In the embodiment, when either the head unit (2) or the sensor unit (12) detects an abnormality, all the CCD cameras (3) and (12a) start operating. This is the CC
This is because the D camera is set so that it can be switched and viewed by an instruction from another monitoring device to which the telephone is connected.

Although not attached in the embodiment, it is also possible to attach a microphone (4) to the sensor unit (12) as in the case of the head. Also, since the sensor unit (12) is mainly used for crime prevention and is rarely used as a videophone, the CCD camera (12a) does not need to be particularly color, and has a high sensitivity black and white so that it can be seen well in a dark place. A camera or an infrared camera may be used.

(13) is a video, and the sensors (4) and (12)
Starts in conjunction with b), and when sensors (4) and (12b) detect an intruder, video (13) automatically starts recording and CC
Recording of an image from the D camera (3) is started, and audio input from the microphone (5) is also recorded at the same time.

Therefore, even if all the contacts are out of the office, the recording by the video (13) can be continued at a minimum, so that the situation of the crime scene can be left as evidence, which is useful for police investigations at a later date. Can be. This video (13) is not special as long as the start timing can be managed, and a normal commercially available video tape recorder can be used.

(14) is a light for illuminating a place where a sensor unit is installed, such as a room or a garage, and (15) is a speaker that emits an alarm sound. Normally, the lights in the room are turned off when you are away, so if there is an intruder at night, the room is dark and the sensor (4) reacts and CC
Even if the D camera (3) is activated, the image is dark and it is difficult to see the state of the room.

Therefore, when the sensor (3) detects an intruder, the light (14) is turned on in conjunction therewith. The light (14) may be a light provided on the ceiling which is normally used, or a light provided exclusively for security purposes.
The number may be singular or plural. The lighting of this light (14) makes it easy to see the indoor situation with a camera,
It also has the effect of surprising intruders and preventing crimes such as theft.

Further, a speaker (15) which emits an alarm sound as a warning to an intruder may be operated in conjunction with the sensor.

A monitor (16) displays an image sent from another monitoring device, displays commands at the time of operating the monitoring device, and displays a partner when used as a videophone. Is used to confirm how the user is captured by the CCD camera.
(17) is a monitor speaker provided in the monitor (16), but may also be used as the above-mentioned alarm speaker.

It is not necessary to use a special monitor 16, and a normal television may be used. When not used for surveillance or as a videophone, the user can enjoy a television program, and if a video (13) is provided, the user can record and play back a television program.

(18) is a sensor connectable to the main body (1). This sensor (18) is not set with the CCD camera, but when an abnormality such as an intruder is detected, the head (2)
The device can be operated in the same manner as when the sensor of the sensor unit (12) detects an abnormality.

Next, the notification procedure and the command of the monitoring device will be described.

FIG. 4 is a diagram for explaining the procedure of reporting. When the sensor detects, all CCD cameras start operating and call the first registration destination by auto-dial (in addition,
Since all the reports resulting from the sensor reaction are auto-dialing, the description of the auto-dialing is omitted hereafter.)

When the connection with the contact partner is established, the process proceeds to the figure. However, when the telephone is not connected even after 45 seconds, the line is temporarily cut off by the automatic cut, and then the telephone call is made to the second partner. Call back. However, if the first call is busy, the call immediately returns to the second call without waiting.

If the second and subsequent contacts are not registered, the first call is made again after an interval of 3 minutes. Here, the interval is set to 3 minutes because the communication rules stipulate that a redial to the same telephone number has an interval of 3 minutes.

If the second call is made and the connection is established with the other party, the process proceeds to the figure. However, if the telephone is not connected even after 45 seconds elapses or if the call is in progress, the line is temporarily disconnected. ,
Call the third party again. If the third and subsequent contacts are not registered, the first call is made again after the automatic cut.

As described above, when the telephone cannot be connected to the contact destination, the next contact is called again. In the embodiment, the number of registered contacts is set to three.
If necessary, four or more contacts may be registered.

When the telephone is connected, the state shown in the figure is reached, and then automatic ID confirmation is performed. In the automatic ID confirmation, the monitoring devices automatically transmit a pre-registered ID to the other party. If the IDs do not match, the telephone line is temporarily disconnected.
The state shown in the figure is reached, and a call is made again from the first contact.

When the ID matches, the transfer of the image from the CCD camera and the sound from the microphone is started. The administrator on the receiving side (reception side) sends a predetermined alert reception confirmation signal, for example, "* 11" to his / her monitoring device within one minute after the line connection in order to notify the transmission side of the reception. Input using a connected telephone. If the alert reception confirmation signal has not been input even after one minute has elapsed, the telephone line is automatically cut, and the next contact is called again.

The reason why the reception confirmation is performed as described above, and if the alert reception confirmation signal cannot be received, the next call is made again is because the significance and operation of the monitoring device for the elderly, children, etc. are notified to the destination contacted by the automatic dial. This is because, if a person who does not know the method appears, it is considered that it is difficult to take appropriate measures even if the video or audio is continuously transmitted. Therefore, by re-calling the next-ranked contact without maintaining the call, it is possible to reliably contact a person who understands the operation.

When "# 7" is input, the voice message recorded on the transmitting side can be heard. As a recording device, a tape, an IC memory, or the like can be used. To use it, leave a message when you are away, or check which store is connected to the phone when there are many stores in the group. "This is the first store in Tokyo." It is conceivable to be able to listen to the message.

When the administrator on the receiving side checks the transmitted video and audio and determines that there is no abnormality, the telephone line is disconnected, and the monitoring device on the transmitting side keeps the alert mode "start" state. However, even if the administrator on the receiving side forgets to disconnect the telephone line, a signal “8 #” instructing the continuation of the alert mode “start” state automatically after a predetermined time (for example, 15 minutes) elapses without any operation. "Is sent, the line is disconnected.

If an abnormality is found, the administrator on the receiving side takes measures such as contacting the police. However, as will be described later, the monitoring device on the receiving side can operate the monitoring device on the transmitting side. An alarm can be emitted from the speaker (15) to surprise and disperse the intruder.

[Command] The command will be described below. FIG. 5 is a diagram for explaining commands in this embodiment. All commands can be sent by telephone push buttons. By pressing the specific instruction button, the instruction is sent to the alarm device, the alarm device is set based on it,
Operated.

Before connection, various settings are mainly made. Press “#” before connection to display the connection setting screen on your monitor, press “1” to connect the line, press “2” to display the automatic reception setting screen, and press “1”. The number of bells for the call can be set, and when "2" is pressed, the ID and the small ID can be set.

If the user presses "*" before the connection, the registration screen is displayed on his monitor, and if he presses "99", the registration screen is displayed.
D can be registered, "01" is the first contact to contact first, "02" is the second contact, "03"
To register the phone number of the third contact.

Although not shown, the telephone line can be switched between the tone type and the pulse type by providing a switch on the main body, but the switch can be switched without providing a separate switch. A command may be provided to enable switching.

Next, various operations by the operating command will be described. If "*" is pressed during operation, a warning / function selection menu is displayed. When "1: warning" is selected, a warning menu is displayed. When "1" is pressed in this state, when a call is received from another monitoring apparatus, a warning reception confirmation signal notifying that the call is being received can be issued. By pressing "4", "start" of the alert mode can be set, and "6" can be set "release" of the alert mode.

When "2: Function" is selected in the warning / function selection menu, a function menu is displayed, and each CCD camera of the destination monitoring apparatus can be switched with "1" to "5". When one or a plurality of CCD cameras are provided in addition to the CCD camera (3) of the head section (2), images captured by an arbitrary CCD camera can be viewed by switching the cameras. Normally, an image from the CCD camera provided as a set with the sensor that detected the abnormality is set to be automatically selected and displayed, but it is possible to see the state of other places and view it at a different angle You can see the image.

"6" can switch ON / OFF of the built-in speaker. When "7" is pressed, the alarm speaker (15) connected to the monitoring device of the transmission destination is leveled and the intruder can be surprised.

Similarly, when "8" is pressed, a message recorded in advance can be reproduced by the monitoring device of the communication destination. The message may be a message that surprises the intruder, such as "Kara! Who!" The recording device may be separately connected, or a small-sized tape recorder or IC memory used for an answering machine may be incorporated in the main body (1).

When "#" is pressed during operation, an image-related menu is displayed. When "1" is pressed, the image displayed on the monitor (16) can be changed into three types: "display only on own side", "display only on opposite side", and "display on both sides". The reason why an image taken by one's CCD camera can be displayed on one's own monitor is to confirm how one's face is displayed on the other party's monitor.

When "2" is selected in the image-related menu, the screen size can be changed. You can switch the screen size. If the screen is small, the image quality is sharp,
The image quality deteriorates as the screen size increases. In the embodiment, it is possible to switch between three stages of "full screen" of full size, "standard" of 1/4 size, and "small" of minimum. When "3" is selected in the image-related menu, the communication speed can be adjusted.

In the image-related menu, "4" is displayed to display a menu for adjusting the angle of view of the CCD camera. From this menu, the photographing range of the other party's CCD camera can be changed via the telephone line.

In the angle-of-view adjustment menu, pressing "1" allows left / right adjustment, and pressing "2" allows up / down adjustment. The CCD camera does not use all the pixels of the CCD, but uses a part of them. Therefore, C
By changing the range of pixels used by the CD camera, an image shifted in that direction can be viewed.

For example, when photographing the front of the camera normally using the pixel at the center and wanting to see a position shifted above or below the front of the camera, the screen is adjusted after the vertical adjustment of “2”. It is good to press a button with a number that moves up or down. Similarly, if you want to see the position shifted left and right, "1"
It is advisable to press the numbered button that moves the screen left or right after pressing the left / right adjustment of. Changing the direction of the camera itself requires a mechanical mechanism such as a motor and a gear, which complicates the apparatus. However, such a change in the angle of view can be easily performed.

Pressing "3" in the angle-of-view adjustment menu changes the zoom. According to this, the digital zoom function allows a wide angle to be projected,
By zooming, a small area can be projected greatly.

When "4" is pressed in the angle-of-view adjustment menu, a still image and a moving image can be selected.

By pressing "5" in the angle-of-view adjustment menu, it is possible to select whether or not to transfer an image. This is in consideration of the case where you do not want the other party to see this state during a videophone call.For example, if you are not wearing makeup, you are not dressed properly after taking a bath, It can be used when there is. If "no image" is set, the call will be made only by voice, and the other party will not be able to see this image.

Although the above description has been made on the assumption that the menu and the input value of the command input are displayed on the monitor (16), a display unit such as a liquid crystal panel (LCD) is provided on the main unit (1) and the display unit is provided. It may be displayed.

Examples of the usage of the videophone device with a security function according to the present invention include monitoring between a store and a home, monitoring between branches of a company, communication between relatives and friends, and the like. The use of the invention is not limited to this.

For example, if a specific post office where no person is in charge at night or on holidays is connected to the post office and the central post office where there is a person in charge for 24 hours, not only crime prevention but also guidance to customers can be performed.

It is also conceivable that a police station is set up at a police box where the user is out of the office during patrol to exchange information between a person with a need and a police station. In this case, since an image can be viewed as a videophone, it is easy to show a map and to teach directions.

Further, it is installed in a farmhouse and a greenhouse,
The person who works in the greenhouse and the farmer may be contacted at home. In this case, if used as a security system, theft of expensive crops such as melons can be prevented, and a temperature sensor can be used as a sensor to notify when the temperature is higher or lower than a predetermined temperature, or a CCD camera can be used. If you put a thermometer and a hygrometer in front of the house and check them on the monitor through a telephone line as appropriate, you can check whether the temperature and humidity of the greenhouse are appropriate while staying at home, and frequently. There is no need to go to a greenhouse and check the temperature and the like.
The present invention has various other applications.
