Description

The present invention relates to a communication system for crime prevention, which is installed in a residential house, a building, various facilities, etc., and notifies the fact of a telephone call for fraudulent purposes or the intrusion of a suspicious person.

In conventional residential security systems, when a suspicious person invades, a battery-powered sensor detects an abnormality and the alarm speaker built into the sensor sounds, and a position wirelessly away from the sensor. There was another device in the above, for example, a ringing device provided with a speaker, which was notified to ring the ringing device. Therefore, the conventional security sensor, for example, when a suspicious person invades, sounds an alarm sound, a voice, or both alternately only in the place where the sounding device is located, but in order to hear the sound, I had no choice but to be in the place where the ringing device was located or to make the ringing device sound loud. In addition, it is difficult to make a hat for fraudulent acts by telephone, and cash and PINs are often given to suspicious telephones.

Further, in a home security system having a door opening / closing sensor that is difficult for an intruder to see with respect to an indoor door, it is provided across the main door and the door frame of the indoor door, and the main door side member and the door frame side member It has a door open / close sensor that detects and outputs the open / close status of the door, and the door is substantially invisible to an intruder standing facing the door, at least in the closed state. A system in which the main door side member of the open / close sensor is embedded in the fore edge side of the main door has been proposed (see Patent Document 2).

Furthermore, in the case of a general security sensor (window, door, ceiling, wall, etc.), the ringing time is short and unnoticed if the device is destroyed in a short time while the person is away. To prevent this, a long ringing is required in the entire building. A result notification mode in which a safety PLC and a safety slave are connected via a safety network to construct a safety network system, determine whether the safety conditions are satisfied based on a plurality of safety input information, and send the requested safety judgment result. , It is provided with two notification modes of detailed information mode that notifies a plurality of safety input information as a set of data as it is, and a method of returning a safety response in either mode according to a command from the safety PLC has been proposed (Patent). Reference 1).

Therefore, the present inventor has developed a new technology and proposed a system in which the speakers of all communication modems installed by utilizing PLC communication sound at almost the same time when an abnormality occurs (see Patent Documents 3, 4 and 5). Here, PLC is called Power Line Communication (power line communication), and is a method of communicating by carrying a data signal on a power line in an existing house. This communication method was first commercialized in 2006 due to deregulation by the Ministry of Internal Affairs and Communications.

(Example 1) Hereinafter, Example 1 of the present invention in which the modem and communication device of the communication system of the present invention configured as described above are incorporated will be described in detail with reference to FIG. As shown in FIG. 1, the telephone P is installed in the living room. This telephone P is a master unit type telephone that wirelessly communicates various information with the slave unit. Communication device K is located near the telephone. Therefore, the communication device K is configured to be able to receive the various signals described above from the telephone which is the master unit type. Further, two first modems M1 and a second modem M2 having the same configuration are connected to the power line A, the first is installed in the living room and the second is installed in the couple's room.

Next, the operation of this embodiment will be described in detail with reference to FIG. Telephone P is a telephone that is generally used at present, and it is possible to register a telephone number, and if there is a call from that telephone number, that telephone number is displayed or the name of the other party is displayed. If it is registered as a pair with a telephone number, the name can be displayed and the name can be pronounced. In addition, the telephone is called from the outside, and while emitting a ringing sound, a wireless signal to that effect is transmitted to the communication device K. Furthermore, if the telephone number of the calling party is set to non-notification or is an unregistered telephone number that is not registered in the memory of the telephone (hereinafter referred to as "unregistered"), the telephone K Transmits a non-notification signal or an unregistered signal, which are signals to that effect, respectively. The communication device K that has received the unregistered signal transmits the unregistered signal to the first modem M, and in step 11, the radio signal receiving unit 36 of the first modem M1 receives it.

After that, when an elderly person in the living room of this house picks up the handset of the telephone P, the telephone P receives a signal (off-hook signal) indicating that the handset is picked up or a call button of the telephone P (not shown). Sends a signal (call start signal) to the effect that is pressed. Therefore, when the communication device K receives the signal, it transmits the signal to the first modem M1 in step 12, and the radio signal receiving unit 36 of the first modem M1 receives it. In step 13, the notification unit 13 transmits a predetermined e-mail to a predetermined destination within a predetermined time after receiving the call end signal in the first modem M1. It should be noted that the calling unit of the notification unit 13 can also make a call with a predetermined telephone number (step 14). Although the mail transmission unit of the notification unit 13 is not connected to the power line of the power line communication, it can be transmitted by other communication methods. This function is the same in other embodiments.

Further, at the same time as or immediately after the notification such as the transmission of the e-mail, the first modem M1 transmits a predetermined request signal to the second modem M2 via the lamp line, and the speaker of the second modem M2. The unit emits a voice corresponding to the predetermined request signal, for example, a voice saying "There is a call from a non-registered person" (step 15). At the same time, the above-mentioned wording "Called by a non-registered person" is displayed on the display screen of the two modems or one of them. Further, when such a display is performed on the display unit, the light emitting unit 21 is blinking. In this display, the telephone P transmits a signal to the communication device K that the telephone number has been called from the registered telephone number, the communication device K receives the signal, and the communication device K receives the signal. It is reset (display ends) by transmitting the signal to the modem. This function is the same in other embodiments.

Further, when the reset is performed, the blinking of the light emitting unit is also stopped. Further, although this reset can also be performed by the operation unit 20, it can be determined by setting whether or not this display is reset only by calling the registered telephone number. This reset method is also the same in other embodiments. Further, for example, after the e-mail is transmitted in the notification, the elderly person finishes the telephone call on the switch unit S of the communication device K (after receiving the on-hook signal by returning the handset). If the button is pressed within the time and the mail transmission request signal from the communication device K is received by the first modem M1, the predetermined mail is transmitted to the same predetermined destination again. Therefore, the content of the first e-mail is set to "There is a call from a non-registered person.", And the content of the second e-mail by pressing the above is set to "Ask for immediate contact." The contents (words) and transmission order of these emails are stored in the storage unit 22.

In this embodiment, in the case of living with two elderly people, it is possible to notify a third party, for example, the son of the elderly person by e-mail that there was a call from an unregistered person, and living with two elderly people. When one of the co-residents is in another room, the speaker section of the second modem there emits the above-mentioned predetermined voice, so that the co-resident also receives a call from an unregistered person. You can know. Furthermore, since the third party who received the above e-mail can contact the elderly person by telephone or the like, even if the unregistered person is a person who intends to fraud. The fraud can be prevented. In addition, if there is no contact from the above third party, if this elderly person presses the switch part of the communication device after making a call, the e-mail will be sent to the above third party again. Can call the attention of the person.

On the other hand, in the case of an elderly person living alone, the utterance from the second speaker unit is stopped for a predetermined time after the above-mentioned telephone call is completed (after on-hooking), but the display of the first and second modems is displayed. The display of the part is maintained as it is without disappearing. This makes it possible to anticipate and maintain a call from the third party. In addition, if the telephone number of the third party to whom the above e-mail is sent is registered, the third party calls this elderly person, that is, there is a match in the comparison of both telephone numbers. If so, those displays will stop. The storage unit 22 and the control unit 25 perform the function.

Further, the modem M and the communication device K have the same configuration as that of the first embodiment. Furthermore, the chest of drawers Q has multiple drawers, but the top drawer contains a bankbook, cash, jewelry, etc. as valuables or important items, and detects that the drawer has been pulled out (opened). The drawer open sensor F is attached.

Hereinafter, the operation of the second embodiment of the communication system of the present invention configured as described above will be described in detail with reference to FIG. Similar to the first embodiment, the telephone P receives a call from the outside, the telephone P detects that the incoming call has been received, and transmits the incoming call detection signal to the communication device K. In step 21, the telephone detection signal receiving unit 35b of the communication device K receives the signal. After that, when the handset of the telephone K is picked up (off-hooked) or a call start detection signal indicating that the call is started is transmitted from the telephone.

In step 22, when the telephone detection signal receiving unit 35b of the modem K receives the detection signal, in step 23, the modem transmits a predetermined e-mail to a predetermined destination by the mail transmitting unit of the notification unit 13. .. At this time, the calling unit of the notification unit 13 can make a call with a predetermined telephone number. After that, the modem M receives the on-hook signal of the telephone or the call start detection signal via the communication device, and then detects the opening of the bowl Q from the opening sensor F (34a) via the communication device K within a predetermined time. When the release detection signal receiving unit 34b receives the signal (step 24), a predetermined e-mail is transmitted or called to a predetermined destination (step 25).

The content of the first e-mail is "There is a call from a non-registered person." And the content of the second e-mail is "The chest has been opened." At the same time, the display unit 19 of the modem M displays that "the chest has been opened". At the same time as or after the above mail transmission, the light emitting unit 21 of the modem also starts blinking. This display and light emission are terminated in the same manner as in the first embodiment. It should be noted that the e-mail may be transmitted in step 23, and the telephone call may be made in step 25. In this case, the person who receives the call can recognize the urgency and importance of making the call because he / she has received the above-mentioned mail once.

Therefore, in this embodiment, for example, when an elderly person receives a phone call from a person who intends to fraud outside and is requested to have a bankbook, and opens the drawer of the chest of drawers Q in which the bankbook is stored. When the opening sensor F is activated and an opening detection signal is transmitted to the modem via the communication device K to send an e-mail to a predetermined third party, the third party sends the opening detection signal to the elderly person. You can call and ask this elderly person the whole story. As a result, it is possible to prevent fraudulent acts by a person who intends to commit fraud aimed at the elderly. As for the configuration of the modem M, the same effect as that of the first embodiment can be obtained by providing a plurality of modems (a second modem in addition to the first modem) as in the first embodiment.

(Example 3) Hereinafter, Example 3 of the present invention in which the modem and communication device of the communication system of the present invention configured as described above are incorporated will be described in detail with reference to FIG. 7.

In addition, by combining this embodiment and the seventh embodiment described later, the switch S of the chime machine L is pressed, and further, after the entrance door D is opened, the switch portion B of the communication device K is pressed. , The modem M may send an e-mail.

(Example 7) Hereinafter, a seventh embodiment of the present invention incorporating the modem and communication device of the communication system of the present invention configured as described above will be described in detail with reference to FIG. An unlocking sensor N (33a) is attached to the entrance door D. The entrance door D is electronic and can be locked and unlocked by an indoor controller (not shown). As for the modem, the first modem M1 and the second modem M2 having the same structure are connected via the power line A as in the first embodiment. In this embodiment, the two modems are arranged apart from each other, and in addition to the two modems, a third modem further separated from each other is provided. This third modem M3 also has the same structure as other modems, and performs power line communication with other modems. For example, the first modem is located at the entrance, the second modem is located in the bedroom, and the third modem is located in the living room, and has its own communication address. Further, when the unlocking sensor N detects the unlocking of the entrance door D, the unlocking sensor N wirelessly transmits an unlocking detection signal to that effect to the communication device K. Further, the first modem M1 is provided with a second motion sensor 24, which detects when a person comes near the entrance door and transmits it to the communication device K.

In the state of being locked by the above controller, for example, when a robber tries to invade and the door D is unlocked, the unlock sensor N that detects the unlocking sends an unlocking detection signal to the communication device. Send to K (step 71). Next, the communication device K transmits the detection signal to the first modem M1. Further, when the second human sensor 24 of the first modem M1 detects the invading robbery within a predetermined time from the unlocking (step 72), the first modem M1 transmits an e-mail of the notification unit 13. The department sends an e-mail saying "Suspected robbery intrusion" to the specified destination. At this time, the calling unit of the notification unit 13 can also make a call with a predetermined telephone number (step 73). At the same time, the speaker unit 18 of the first modem issues an alarm sound and an announcement that "currently recording is being recorded" (step 74).

Further, an announcement "suspected robbery intrusion" is made from the second speaker unit of the second modem M2 provided in the bedroom separated from the first modem M1. Further, when the resident presses the switch S of the communication device K within a predetermined time after the second motion sensor 24 detects a person, a predetermined e-mail is transmitted to a predetermined destination again. (Step 76) At this time, the calling unit of the notification unit 13 can also make a call using a predetermined telephone number. The content of the email is "There is a robbery intrusion." At the same time, a louder alarm sound and an announcement "It is a robbery. It is a robbery." Are made from the first speaker unit of the first modem (step 77).

Here, if the robber breaks the first modem M1 in an attempt to stop the announcement from the speaker section of the first modem M1, the third modem installed in the living room and has not been operated until now. The failure detection unit 23 of the M3 detects the failure and starts an announcement from the speaker unit with an old man alarm sound and "Danger, save."

In this embodiment configured in this way, when the locked entrance door is unlocked, the occupants in the room are alerted, and for example, a communication device determined to be invaded by a suspicious person is carried. When the resident presses the switch, an alarm sound is emitted from another modem, so that a strong threatening effect can be expected, and a high crime prevention effect can be expected.

If either of the first and second modems is damaged by an intruder while the alarm sound is being emitted, the failure detection unit 23 that detects this damage causes the third modem to fail. The third modem M3, which transmits a detection signal (alarm request signal) and receives the signal, issues a louder alarm sound and a save command from the speaker unit. Therefore, when multiple modems are deployed, if one ringing modem is damaged, the modem located farthest from that modem is set to ring, and the far-located modem is damaged. If so, the modem located farthest from this damaged modem can be set to ring. With this setting, an intruder into a dwelling would have to go back and forth in the dwelling to stop the ringing modem, struggling to stop the ringing modem, and leaving the dwelling. ..

The alarm sound of the third modem activates the third alarm, and the intruder receives a stronger threat and disperses to prevent crime.

Further, as described above, the alarm sound from the speaker unit of the modem cannot be stopped by the operation by the operation unit of each of the modems. That is, when there is a call from a telephone with a registered telephone number from a telephone installed near the communication device K, the telephone transmits a signal indicating that the call is from the telephone with the registered number. Upon receiving the signal, the communication device K causes the speaker units of the first modem and the second modem to stop producing the alarm sound.

The power line communication device of the present invention is arranged in a house, a building, or other facility of a general household, and has high industrial applicability because it can immediately notify an indoor abnormality indoors or outdoors.
