BACKGROUND OF THE INVENTION
The present invention relates to a home security system using broadband, and more particularly, to a home security system and a method thereof capable of appropriately responding to a visitor at an answering house from a mobile phone terminal of a home away from home.
[0002]
[Prior art]
Conventionally, interphone systems provided at homes use a TV camera to photograph the visitors at the front door, and see them on a monitoring television receiver (monitor) in the house to discriminate the visitors. It was. Therefore, if there was a distrustful person in the visitor and there was no response, the key could be unlocked and pushed into the house to work the empty nest. Therefore, several systems have been proposed that can respond to visitors at home even when going out.
[0003]
For example, in an interphone system, a visitor is photographed with a video camera, a video signal output from the video camera is captured and stored in a memory, and the signals stored in the memory are sequentially read to comply with a facsimile standard. A signal that is converted into a signal and output to the outside is proposed (for example, see Patent Document 1).
[0004]
Conventionally, as an absence management system, an absence management system for houses, business establishments, etc., when there is a visitor in the absence of the visitor, in response to the visitor, accepting the will indication issued from the visitor, Alternatively, a visitor-compatible device for transmitting a response to the issued will indication to the visitor, a central processing unit connected to the visitor-compatible device via an interface, and a storage device for storing data and programs The information transmission / reception device is arranged on the side of the house, business office, etc., and the portable terminal that is carried when going out has a central processing unit, a storage device for storing data and programs, and an information transmission / reception device. Information for maintenance management created by the program read from the storage device by the central processing unit on the side of the house, business office, etc., and the central processing unit on the mobile terminal side An absence management system has been proposed in which information for maintenance management created by a program read from a storage device is sent and received between the side of a house, office, etc. and the side of a portable terminal with each other's transmission / reception device. (For example, refer to Patent Document 2). The absence management system includes a delivery receiving device that receives a delivery including a home delivery service, and the delivery receiving device includes a means for signing or stamping the delivery.
[0005]
Also, if there is a portable communication terminal indoors that functions as a cordless telephone by connecting wirelessly to a main unit connected to a public line, and that functions as a cellular phone by connecting to a public base station when taken outdoors If the mobile communication terminal is indoors, the outdoor intercom means for at least voice interaction with the visitors at the front door is connected to the indoor intercom means and the indoor intercom means is used. When the mobile communication terminal is taken out outdoors, the outdoor interphone means is connected to the main unit, and by using the mobile communication terminal connected via the main unit, it is possible to set the absence, etc. When you go out with your mobile communication device, you can use the mobile communication device with the visitors at the entrance. It has also been proposed availability of good intercom system (e.g., see Patent Document 3).
[0006]
A conventional intercom system described in Patent Document 3 will be described with reference to FIG. In this interphone system, as shown in FIG. 7, the outdoor mechanism unit 200 includes an outdoor interphone microphone 201 and an outdoor interphone speaker 202. When the interphone is pressed, the connection destination is switched under the control of the control unit 104. The unit 103 is connected to either the indoor mechanism unit 100 including the indoor interphone microphone 101 and the indoor interphone speaker 102 or the PHS base unit 301. When the user is at home, normal audio is exchanged with the indoor interphony means 100, and an image from the CCD camera 203 provided at the entrance is also output and displayed on the display unit 108 as necessary.
[0007]
When the user is away and is in a remote location, the connection destination switching unit 103 selects the PHS base unit 301. The PHS base unit 301 passes through the slave unit position determination / mode switching unit 302 to connect the general public line and the PHS public line. Then, the audio signal from the outdoor interphone microphone 201 is transmitted to the PHS cordless handset 303 at a remote place (outdoor). At this time, the display display unit 108, which is a visit information signal generation means, responds to a visit via the PHS master unit 301 when an unillustrated interphone button of the front door mechanism unit 200 is pressed under the control of the control unit 104. A visit information signal indicating a call is transmitted, and information indicating an interphone call is displayed on the display of the PHS slave unit 303.

Here, although the CCD camera 203 is used to photograph visitors at the entrance, this camera may be a normal video camera. The video data captured by the CCD camera 203 is temporarily stored in the transmission image memory 209, and the stored transmission image is transmitted to the PHS slave unit 303 and also to the designated FAX 401.
[0009]
The control unit 104 includes a CPU, a RAM, and a ROM, and a control program as an interphone system is stored in the ROM. The CPU of the control unit 104 uses the RAM as a work memory, controls each part of the interphone system based on a control program in the ROM, and functions as an interphone system.
[0010]
That is, when there is a visitor and an interphone button (not shown) is pressed, the control unit 104 connects the outdoor interphone microphone 201 and the outdoor interphone speaker 202 to the indoor interphone microphone 101 and the indoor interphone speaker 102. The reception voice by the indoor interphone microphone 101 is output from the outdoor interphone speaker 202, and then the voice from the outdoor interphone microphone 201 is output from the indoor interphone speaker 102, and the outdoor interphone microphone 201, the outdoor interphone speaker 202, and the indoor interphone microphone 101 are output. And an interphone response by the indoor interphone speaker 102.
[0011]
Further, when the handset position determination / mode switching unit 302 attached to the PHS base unit 301 detects that the PHS handset 303 is outdoors (including a remote place), the PHS base unit 301 includes the PHS handset 303. Is switched to a relay mode in which the outdoor interphone microphone 201 and the outdoor interphone speaker 202 are connected to the PHS slave unit 303 via a line, and the PHS slave unit 303 is connected to the control unit 104 outdoors. Notify that Therefore, the PHS handset 303 functions as a normal PHS.
[0012]
When the PHS cordless handset 303 is outdoors, the control unit 104 controls the connection destination switching unit 103 to connect the outdoor interphone microphone 201 and the outdoor interphone speaker 202 to the PHS base unit 301, so that the outdoor interphone microphone 201 and the outdoor interphone are connected. It operates as an interphone function using the speaker 202 and the PHS slave unit 303.
[0013]
Therefore, when there is a visitor and an interphone button (not shown) is pressed, the control unit 104 connects the outdoor interphone microphone 201 and the outdoor interphone speaker 202 to the PHS base unit 301, and the PHS base unit 301 is connected to the public. The PHS slave unit 303 is called through the line and the PHS public base station, and the answering voice by the PHS slave unit 303 is output from the outdoor interphone speaker 202. Thereafter, the audio from the outdoor interphone microphone 201 is transmitted to the PHS slave unit 303 via the PHS master unit 301 and output from the speaker of the PHS slave unit 303, and the outdoor interphone microphone 201, the outdoor interphone speaker 202, and the PHS slave unit are output. Intercom response by 303 is made possible.
[0014]
In addition, in the device described in Patent Document 3, a fixed message generator 106 is provided in which a plurality of types of voice messages output to a visitor at a front door are stored in a RAM or the like. One of the plurality of stored voice messages selected by the fixed message selection unit 105 is output from the outdoor interphone speaker 202. Even when the PHS cordless handset 303 is outdoors, one of voice messages of the fixed message generating unit 106 can be designated from the PHS cordless handset 303 and can be output to the outdoor interphone speaker 202. ing. Thereby, it is possible to appropriately respond to an important visitor who has not been scheduled to visit with a voice message stored in advance without responding to the mobile communication terminal. In addition, a voice message is appropriately selected and output in accordance with the type of visitor such as a visitor of unscrupulous salesman or collection of newspapers, etc., so that a response suitable for the type of visitor can be performed.
[0015]
In addition, in order to improve the work efficiency of condominium managers who have a lot of waiting time and less work hours, a manager's agent that aims to manage multiple apartments at the same time by performing the manager's work remotely. A system for automatically unlocking a front door of a condominium having a plurality of dwelling units and a common facility in one building, a reception terminal provided in the front hall of the apartment, Also connected to the control server is an absentee courier storage device for temporary storage of parcels by courier to an unoccupied house in the entrance hall, and a shared facility key storage device installed at the place of the apartment.

[Problems to be solved by the invention]
However, the interphone system or the absence management system as described above has many problems in terms of convenience when going out. In other words, in the interphone system described in the above-mentioned Patent Document 1, it is possible to send a picture taken by a video camera by facsimile, but if the destination changes from moment to moment, the picture is sent by facsimile transmission. There was a problem that it was inconvenient because the destination could not be switched and transmitted.
[0018]
In the absence management system described in Patent Document 2, information can be transmitted and received between the portable terminal and the visitor-compatible device, and the absence management using the portable terminal can be performed. The terminal is a portable terminal dedicated to the absence management system, and needs to be improved in order to improve versatility and usability. Also, in this absence management system, the delivery receipt device can sign or seal delivery receipt, but this delivery receipt device is dedicated to receiving delivery items such as courier, and costs However, it was still necessary to improve the versatility.
[0019]
Furthermore, although the intercom system described in Patent Document 3 can talk to a visitor at the entrance on the go using a portable communication terminal such as a PHS handset, in the case of a close acquaintance, etc. In the case of a courier who knows how to open the door and return home, it is not assumed that the door will be unlocked for a while and the item will be left behind. . Further, it has not been considered to control various lighting devices, home appliances, crime prevention devices, etc. installed outdoors and indoors by using a mobile phone with a browser function.
[0020]
In addition, the manager's agent system described in Patent Document 4 has been shown to unlock the key to the apartment entrance in response to a visitor who visits the entrance to the apartment from a remote location. I couldn't decide whether to unlock or not. In addition, although this manager system has various service functions for each householder, such as a voice message reception function for absentees and a courier receipt function for absentees, the manager's agency service is only provided. There is a problem that the system becomes large to implement in each individual home.

DETAILED DESCRIPTION OF THE INVENTION
Next, an example of an embodiment of the present invention will be described based on the block diagram of FIG. Reference numeral 1 denotes a server, which controls the entire server and converts the image from the camera into Web content, confirms the state of the security sensor, etc., locks and unlocks the electronic lock, and confirms the opening / closing state of the door. Web server function unit 3 and video from the outdoor intercom camera are converted to video or still image format and transferred to the monitor display unit of the indoor interphone or transferred to the mobile phone with browser function via the Internet and mobile phone network The image processing unit 4 having a function of recording a simple image in a memory device (not shown) in the server and the voice from the external interphone microphone are transferred to the telephone, the voice from the mobile phone is transferred to the speaker of the outdoor interphone, Appropriate according to the situation from a plurality of voice messages stored in advance in the time response table 8 The voice processing unit 5 that synthesizes the selected one and transfers it to the outdoor interphone speaker as a voice message, and various outdoor or indoor security sensors, control of opening and closing of the electronic lock, etc. via the interface 11, fire alarm, lighting When the server communicates the presence of visitors to the external I / F processing unit 6 that controls devices and various home appliances, and when the server cannot connect to the mobile phone for a certain period of time, the mail correspondence table 9 The mail server function unit 7 selects an appropriate mail message from among a plurality of mail messages stored in advance and transmits it to a mobile phone of a home away from home.
[0029]
The server 1 is always connected to the Internet 12 and is connected to a mobile phone 15 with a browser function via a mobile phone network 14 that is also connected to the Internet 12. The mobile telephone network 14 is an IP telephone network, and is operated by an IP telephone company 13 that subscribes to the telephone network. The server 1 is connected to the outdoor interphone system via a wired LAN or a wireless LAN, and the video captured by the outdoor interphone camera and the sound collected by the outdoor interphone microphone are sent to the server 1.
[0030]
Further, the server 1 stores a normal response table 8 in which a plurality of voice messages are stored, and a plurality of mail messages for notifying a visitor or a suspicious person intrusion on a mobile phone of a home away from home. An email response table 9 and an emergency response table 10 in which a voice message for notifying an out-of-home person such as an intrusion of a suspicious person is stored.
[0031]
Furthermore, the server 1 includes various security sensors 17, indoor electronic locks 18, fire alarms, lighting devices, heating devices, and various home appliances installed indoors or outdoors via the external I / F processing unit 6 and the interface 11. And the like, and the state of these various devices is communicated to a home away from home, and these various devices are controlled using a mobile phone outside the home. The server 1 is connected to the outdoor interphone with camera 16 and the security camera 20 that are installed outdoors by wireless or wired LAN.
[0032]
In the home security system of the present invention, for example, one security sensor is attached to the window glass, and an alarm is sent to the external I / F processing unit 6 when the window glass is broken. The external I / F processing unit 6 processes signals from these various security sensors under the control of the control unit 2, passes through the Internet 12, the IP telephone company 13, and the mobile phone network 14, and the mobile phone with a browser function of a home away from home Inform phone 15.

Furthermore, the outdoor interphone camera has a function to compare the camera images at regular time intervals and extract the difference. For example, when standing in front of the visitor camera, recording starts automatically or the visitor presses the interphone button. Even without this, the buzzer of the indoor intercom is sounded so that the housekeeper can detect the presence of visitors.
[0038]
Then, when the outdoor interphone camera catches a suspicious person who appears at the front door while away from home, it is transmitted to the mobile phone 15 held by the householder on the go, for example, for crime prevention provided outdoors from the mobile phone 15 on the go The camera 16 is actuated so that an image captured by this camera can be stored in a storage device (not shown) in the server 1. Also, as if you were at home, you could turn on an indoor lighting device or intimidately say “Which way?” From the outdoor interphone speaker to intruders. It is also possible to respond.
[0039]
As described above, the home security system of the present invention can be used for various purposes, and FIG. 2 shows an example of an embodiment of the present invention as a flowchart.
First, when the intercom button is pressed (step S1), the control unit 2 of the server 1 determines whether or not the absence mode is set (step S2). When the server 1 is not in the absence mode, i.e., when the housekeeper is at home, the normal response mode for transmitting a response signal from the indoor interphone microphone to the outdoor interphone speaker after confirming the visitor on the indoor interphone monitor (Step S3).
[0040]
If it is determined in the determination step S2 that the user is in the absence mode, then it is determined whether or not the control unit 2 in the server 1 is in the automatic response mode (step S4). If it is determined that the automatic response mode is selected, the normal response table 8 storing a plurality of voice messages is searched (step S5).
[0041]
Next, it is determined whether there is an appropriate corresponding phrase in the normal response table 8 according to the situation at that time (step S6). If there is a corresponding phrase, the phrase is selected and the server 1 The recorded message is transmitted to the outdoor interphone speaker by the voice processing unit 5 (step S7).
[0042]
If it is determined in the determination step S4 that the server 1 is not in the automatic response mode, the voice processing unit 5 dials the IP telephone network to connect the server 1 to the mobile phone (step S8).
Then, it is determined whether or not the home away from home has answered the phone within a predetermined time, for example, 20 seconds (step S9). The process is terminated by directly connecting to the interphone and talking with the visitor (step S11).
[0043]
In the determination step S6, if it is determined that there is no corresponding message in the normal time response table 8 in which the voice message is recorded, the process proceeds to step S8 and dials into the IP telephone network. Do.
[0044]
In the judgment step S9, when the housekeeper who is away from the house does not come out to the telephone port within a certain time, the mail server function unit 7 in the server 1 is activated and some messages are stored in advance. An appropriate message is selected from the table 9, and the fact that there was a visitor is notified by mail transmission to the mobile phone 15 of the outing home via the Internet 12 and the mobile phone network 14 (step S10).
[0045]
FIG. 4 shows an example of automatic response items stored in correspondence with a presumed visitor in the mail correspondence table 9, and the mail server function unit 7 in the server 1 recognizes the visitor. Then, an appropriate one of the response IDs is selected and mail is transmitted to the mobile phone 15 of the home away from home.
[0046]
FIG. 5 is a flowchart for explaining the operation of the home security system of the present invention when another example of the embodiment of the present invention, that is, a suspicious person enters the site.
When the suspicious person opens the front door or breaks the window and enters the room (step 20), various security sensors 17 attached to the front door or the window are activated to detect the intruder (step 21).
[0047]
When an intruder is detected, it is next determined whether or not the server 1 is in the absence mode (step 22). If it is not in the absence mode, an indoor lamp is turned on or an alarm is sounded to intimidate and dissipate the intruder (step 23).
[0048]
If it is determined in the determination step 22 that the user is in the absence mode, the server 1 automatically dials the IP telephone network and calls the mobile phone 15 of the home away from home (step 24). Next, it is determined whether or not the householder answered the phone within a predetermined time, for example, within 20 seconds (step 25), and when the telephone is answered within the predetermined time, it is stored in the emergency response table 10. The automatic response items as shown in FIG. 6 are appropriately selected according to the situation such as the intrusion place, and after being subjected to voice synthesis processing by the voice processing unit 5, they are transmitted as voice messages to the householder on the go. For example, when a suspicious person breaks a window glass and enters the room, a message “The window has been opened. Please immediately turn 110.” is sent to the home away from home.
[0049]
In addition, when a suspicious person is jealous in the mansion, a related response item, such as “Suspicious person is jealous in front of the intercom. Look at the camera image.” Is sent to the mobile phone 15 of the home away from home.
[0050]
If it is determined at step 25 that the home away from home does not answer the call within a certain time, for example, within 20 seconds, the response ID 5 shown in FIG. Linked to table 10. Then, an appropriate message corresponding to the situation is selected from the emergency response table 10 and is sent by e-mail to the mobile phone 15 of the home away from home under the control of the mail server function unit 7 (step 27).
[0051]
Here, in FIG. 1, the normal response table 8, the mail correspondence table 9, and the emergency correspondence table 10 are described as separate files, but it goes without saying that addresses in the same file can be used separately. Absent. In addition, the automatic response items of the normal response table 8, the mail response table 9, and the emergency response table 10 shown in FIGS. 3, 4, and 6 are merely examples of assumed cases. In addition to those described above, automatic response items corresponding to various application ranges are included.
[0052]
【The invention's effect】
As described above, according to the home security system and method of the present invention, the image taken by the outdoor interphone camera is transmitted to the mobile phone with the browser function on the go, and the visitor at the front door is confirmed from the go. In addition to being able to respond appropriately, it is also possible to respond appropriately to suspicious intruders from the outside. In addition, since various devices such as fire alarms, lighting devices, crime prevention devices, and home appliances installed indoors or outdoors from outside can be monitored and controlled, the householder can leave the house with peace of mind.
