TECHNICAL FIELD OF THE INVENTION
The present invention relates to a security system for general houses, condominiums, offices, stores, factories, and the like.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a security system for preventing a theft accident or a fire accident in a security target such as an office, a store, a factory, and the like has been widely known. This is because a sensor that can detect an external intruder, such as a moving object detection sensor or an infrared sensor, is installed in advance in the security target object, and when an abnormality is detected by those sensors, a transmission provided separately is provided. The device transmits abnormal information to a management center provided outside.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned conventional security system, large-scale construction work such as installation work of a sensor and a transmitter and wiring work for connecting the sensors and the transmitter are required, and the construction cost for the installation has been increased.
[0004]
In particular, in recent years, theft by suspicious individuals and stalking of women living alone have frequently occurred.Therefore, similar security systems have been used not only in offices, stores, factories, etc., but also in private homes and condominiums. The demand for introduction is increasing. For this reason, reducing the cost of introducing a security system is also a social demand.
[0005]
In order to meet such a request, a security system described in Patent Document 1 has been proposed.
[Patent Document 1]
JP-A-2000-40194
[0006]
In this security system, a security device for detecting a security abnormality and transmitting the abnormality information to the outside is provided in a portable box. For this reason, when the security device is installed on a security object, installation work such as installation work of sensors and transmitters and wiring work for connecting them are almost unnecessary, and the construction cost can be significantly reduced. There is also an advantage that the alarm area can be easily changed by moving the security device.
[0007]
However, in this security system, the abnormality information transmitted from the security device is simply reported to a preset telephone number (usually a security company management center) via a telephone line. For this reason, when notifying abnormal information to a plurality of notifiers, the management center has again contacted the notifiers by telephone or the like. For this reason, a large number of personnel must be allocated to the management center, and the installation cost and operation cost of the security system as a whole have also been high.
[0008]
The present invention has been made in view of the above-described conventional circumstances, and the construction cost for installing a security device is low, the alarm area can be easily changed, and the cost for installation and operation of a management center is low. The challenge is to provide a secure security system.
[0009]
[Means for Solving the Problems]
The security system of the present invention is provided in a living space, and includes a detection unit for detecting a security abnormality, and a transmission unit for transmitting abnormality information to the outside based on an abnormality signal emitted from the detection unit. In a security system including a security device provided and a management center for receiving the abnormality information transmitted from the security device and transmitting the abnormality information to an information terminal of a notifier, the security device is easily carried by a person. It is possible, and it can be driven by at least one of the supply of electricity from the outlet or the built-in battery, and the management center sends the abnormality information transmitted from the security device to the information terminal having a plurality of notifiers. And a server for transmitting the abnormal information to the plurality of notifiers. Characterized in that it be done by mail delivery using the network are possible.
[0010]
In the security system of the present invention, the security device can be easily carried by a person, and the security device can be driven by at least one of a power supply from an outlet and a built-in battery. Therefore, if this security device receives power from an outlet, the installer places the security device in an appropriate location on the security object, plugs it into the outlet, and transmits abnormal information as necessary. The installation is completed only by connecting the wiring for this. Further, when this security device is driven only by a battery, it is not necessary to even insert a plug into an outlet. For this reason, installation work of a security device, electric wiring work, etc. become almost unnecessary, and since it can be installed easily even by a non-specialized contractor, the construction work cost is hardly required. Further, since the security device can be easily carried by a person, it is very easy to change the alarm area. Furthermore, if this security device can be used for both the supply of electricity from the outlet and the supply of electricity from the battery, even if the plug of the security device is pulled out from the outlet by a suspicious person, etc. The device will be supplied with electricity and the security device will not be shut down.
[0011]
Further, the server provided in the management center automatically distributes the received abnormality information to the information terminals of a plurality of notifiers by mail, so that the management center can be operated almost unattended. For this reason, the operation cost of the management center is also low. In addition, by sending the abnormal information to the plurality of notifiers by mail, the notifier can know the abnormality in the living space, and can perform more appropriate processing. Here, the plurality of notifiers are those who have been designated in advance as contacts, and can be set freely. For example, a resident (hereinafter, simply referred to as a “resident”) of a living space provided with a security device, a sibling, a parent and child, a relative, a boss, a friend, a guardian, and the like can be considered. Of course, it is also possible to arrange personnel at the management center and direct security personnel to the site based on the abnormality information.
[0012]
Therefore, according to the security system of the present invention, the construction cost for installing the security device is low, the change of the alarm area is easy, and the cost for setting and operating the management center is low.
[0013]
The server is capable of distributing mail by providing a time lag in the order of priority to information terminals of a plurality of notifiers whose priorities are set in advance, and the information terminal of the notifier has: It is possible to transmit confirmation information indicating that the abnormality information has been confirmed to the server, and the server that has received the confirmation information sends the confirmation information to an information terminal other than the information terminal that transmitted the confirmation information. It is preferable to be able to stop the mail distribution of the abnormality information by using this method. In this case, it is possible to stop unnecessary mail distribution of abnormal information. In addition, when the abnormal information is transmitted due to the occupant's error, it is possible to prevent the notifier from having extra uneasiness. For example, when the security system according to the present invention is operated, but the user enters the alarm area as it is, or when the occupant activates the security system before leaving the alarm area, This is the case when the user goes out with a pet or the like placed in the area. In such a case, the resident who determines that the mail distribution is unnecessary transmits the confirmation information to the server, so that the mail distribution of the abnormal information to the notifier having the lower priority can be stopped. For this reason, such a notifier does not need to feel extra uneasiness.
[0014]
It is preferable that the server be capable of transmitting abnormal information by voice as well as mail distribution. In this case, even a notifier who does not know the operation method for viewing the delivered mail can reliably know the abnormal information by voice.
[0015]
In this case, the server that has received the confirmation information from the information terminal of the notifier sends an e-mail of safe information indicating that the abnormality has been confirmed to the information terminal of the notifier who has already completed the mail distribution of the abnormality information. More preferably, it is possible to do so. In such a case, the notifier who has already received the mail of the abnormal information is notified that the abnormal information has been confirmed due to an error or has been dealt with. Can be given.
[0016]
As for the method of transmitting the abnormal information in the security device, any method capable of transmitting the abnormal information, such as a telephone network using a mobile telephone, a telephone network using a fixed telephone, a dedicated wireless device, a wired transmitting device using a dedicated cable, or the like. Can be used.
[0017]
In particular, if the transmission method is performed by a telephone line network using a mobile telephone, there is no need to connect the security device and the telephone line with a modular cable, which simplifies the construction and allows the telephone to be installed in a place where no telephone is laid. This also makes it possible to install a security device, which is preferable. As such a telephone line network using a mobile telephone, for example, there is a packet communication service “DoPa” network provided by NTT DoCoMo, Inc. In the case of performing communication through this “DoPa” network, by attaching a data adapter compatible with packet communication inside the security device, it is possible to easily transmit abnormal information by packet communication.
[0018]
If the transmission method is a fixed-line telephone line network, if there is a fixed-line telephone line at the place where the security device is installed, a new mobile telephone line network contract is made, This is preferable because there is no need to incorporate a transmission device and the cost required for communication can be reduced.
[0019]
As the information terminal of the notifier, any information terminal that can receive mail distribution, such as a mobile phone and a personal computer, can be used. If the information terminal is a mobile phone, mail notification can be received wherever the notifier is located, which is preferable.
[0020]
Further, it is preferable that the security device is provided with a plurality of detecting means, and a part or all of the detecting means is separated from the transmitting means. In this case, it is possible to install the detection means in various places such as a door, a window, a door, each room, a garden, and the like as necessary, and more complete security can be secured.
[0021]
The security device is provided with an ultrasonic sensor and an infrared sensor as detection means, and transmits the abnormality information to the outside only when both the ultrasonic sensor and the infrared sensor detect a security abnormality. It is preferred that The principle of the ultrasonic sensor is to detect a moving object by detecting a difference between the frequency of the transmitted ultrasonic wave and the frequency of the ultrasonic wave reflected by the measured object. For this reason, if the object is a moving object, even a flying paper waste or ball is detected, which causes a malfunction. In addition, the infrared sensor detects anything that generates heat, so that it operates even when the air conditioner is driven by a timer near the infrared sensor, and also malfunctions. In this regard, if both the ultrasonic sensor and the infrared sensor transmit anomaly information to the outside only when a security anomaly is detected, such malfunction can be prevented, and the anomaly information can be prevented. Will be dramatically improved.
[0022]
It is preferable that the security device emits a warning sound when a predetermined time has elapsed after the detection of the security abnormality. In this case, it is possible to threaten the suspicious person and urge him to leave.
[0023]
The appearance of the security device is similar to the appearance of items normally placed in the living room space (for example, VCRs, clocks, clocks, lighting fixtures, computer game machines, flower pots, vases, clogs, pillows, books, etc.). It is also preferable that it is done. In such a case, the security device becomes inconspicuous, it is difficult to impair the aesthetic appearance, and it is difficult for a suspicious person to find the security device.
[0024]

The device 11e is driven, and the speaker 11i informs the user that "the security system starts to operate." Then, after the elapse of a predetermined time set in advance, the security device 1 starts detecting a security abnormality. The resident will leave the house within this predetermined time.
[0033]
When the suspicious person or the like approaches the base station 11, the infrared sensor 11a emits an infrared detection signal due to infrared rays emitted from the suspicious person, and the ultrasonic sensor 11b detects the movement of the suspicious person. To generate an ultrasonic detection signal. These detection signals are transmitted to the control unit 11e. Then, when those detection signals continue for a certain period of time or more, the transmission unit 11f transmits abnormality information regarding the entry of the suspicious individual. That is, the transmission of the abnormal information related to the entry of the suspicious individual from the transmission unit 11f is considered when both the infrared sensor 11a and the ultrasonic sensor 11b detect the detection signal for a certain time or more. For this reason, it is possible to prevent a malfunction caused by a passing person or the like who has temporarily passed near the base station 11, and the reliability of the abnormal information is dramatically improved. Further, a threatening sound is emitted from the speaker 11i together with the transmission of the abnormal information. For this reason, the suspicious person is forced to leave due to the threat of the threatening sound.
[0034]
When a suspicious person or the like approaches the substation 12, the infrared sensor 12a and the ultrasonic sensor 12b detect the suspicious person and emit a detection signal. These detection signals are transmitted to the receiving unit 11h of the base station 11 shown in FIG. 3 via the wireless transmitter 12d shown in FIG. 4, and then the infrared sensor 12a and the ultrasonic sensor 12b are operated by the same operation as described above. Only when both of them detect the detection signal for a certain period of time or more, the transmitting unit 11f transmits the abnormal information regarding the entry of the suspicious individual.
[0035]
Further, when the suspicious individual breaks the window glass to which the glass alarm 13 shown in FIG. 5 is attached by the suspicious individual, the ultrasonic wave generated at that time causes the ultrasonic sensor 13a to emit an ultrasonic detection signal. This ultrasonic detection signal is transmitted by the wireless transmitter 13b to the receiving section 11h of the base station 11 shown in FIG. Then, abnormal information relating to glass breakage is transmitted from the transmission unit 11f via the control unit 11e.
[0036]
In this way, the abnormal information regarding the intruder and glass break transmitted from the transmitting unit 11f of the base station 11 is transmitted to the server 2a of the management center 2 via the wireless telephone line network using the packet communication method as shown in FIG. Sent. Then, the server 2a performs mail distribution to the mobile phones 3a to 3e of the first to fifth notifiers in the following procedure according to the flowchart shown in FIG.
[0037]
That is, when the abnormality information arrives at the server 2a, the arrival time is recorded (step S1), the notifier database recorded beforehand is referred to (step S2), and a setting is made so that mail distribution is performed from among them. The e-mail addresses and telephone numbers of the first to fifth notifiers that have been used are acquired (step S3). Then, "0" is stored in the mail distribution flag (step S4), a timer built in the server 2a is started (step S5), the mail is distributed to the cell phone 3a of the first notifier, and the synthesized voice is used. A telephone notification of the abnormality information is performed (step S6).
[0038]
Further, when the first notifier opens the e-mail delivered to the mobile phone 3a, a warning 20 urging confirmation of abnormal information is displayed on the display screen of the mobile phone 3a as shown in FIG. It is displayed together with the display 21. Thus, the first notifier can quickly know that there is an abnormality in the room. Then, when the first notifier clicks the address display 21, a confirmation button 22 shown in FIG. 8 is displayed. When the first noticer clicks the confirmation button 22 (step S7), the server 2a of the management center 2 shown in FIG. 1 stores "1" in the mail distribution flag (step S8). The display screen shown in FIG. 8 also displays a contact telephone number for requesting an emergency dispatch. Therefore, the first notifier who has confirmed the abnormality information can return home safely and safely by calling the contact information and requesting that the security officer return home.
[0039]
Further, as shown in FIG. 6, the server 2a of the management center 2 determines whether or not the timer has passed 10 seconds in step S9, and if so, determines whether or not the number of the mail delivery flag is 0 or 1. (Step S10). If the number of the mail distribution flag is “1” (that is, if the confirmation button 22 shown in FIG. 8 has already been pressed by the first notifier), the process ends without performing the subsequent processing. As a result, the first notifier stops the mail distribution of the unnecessary abnormality information to the second to fifth notifiers. In addition, when the mail delivery of the abnormal information is transmitted due to the occupant's error, it is possible to prevent the second to fifth notifiers from feeling uneasy.
[0040]
On the other hand, as shown in FIG. 6, when the number of the mail distribution flag is “0” in step S10 (that is, when the confirmation button 22 shown in FIG. 8 has not yet been pressed by the first notifier), (2) A mail is delivered to the notifier's mobile phone 3b (see FIG. 1), and a notification of the abnormal information is made by a synthesized voice. (Step S11). Thereby, the second notifier can know that there is an abnormality in the room. Then, the same processing as in steps S7 and S8 is performed (steps S12 and S13).
[0041]
Further, in step S14, it is determined whether or not the timer has elapsed for 120 seconds. If the timer has elapsed, it is determined whether the number of the mail distribution flag is 0 or 1 (step S15). If the number of the mail distribution flag is “1” (that is, if the confirmation button 22 shown in FIG. 8 has already been pressed by the first notifier), the process ends without performing the subsequent processing. As a result, the mail distribution of unnecessary abnormal information to the third to fifth notifiers is stopped, and it is possible to prevent the third to fifth notifiers from feeling uneasy.
[0042]
On the other hand, if the number of the mail delivery flag is “0” in step S15 (that is, if the confirmation button 22 shown in FIG. 8 has not yet been pressed by the first notifier and the second notifier), the third to The mail is delivered to the mobile phones 3c to 3e (see FIG. 1) of the five notifiers, and a telephone notification of the abnormal information is made by synthetic voice (step S16). Thereby, the third to fifth notifiers can know that there is an abnormality in the room. In this way, the mail notification indicating the abnormal information and the telephone notification of the abnormal information by the synthesized voice are made to the first to fifth notifiers as necessary (step S17).
[0043]
Further, it is determined whether or not the confirmation button has been clicked from the first to fifth notifiers. If any of the notifiers has clicked the confirmation button, the confirmation button is clicked. The secure mail 23 shown in FIG. 9 is delivered to the mobile phone other than the notifier, and a telephone notification of the same content is made by the synthesized voice, and the transmission of the abnormal information by the security system of the embodiment ends. By opening the mail, the notifier who receives the delivery of the safe mail 23 can know that the past abnormal information has been resolved, and does not need to feel extra uneasiness. .
[0044]
In the security system of the above embodiment, since the base station 11 is in the form of a book, it can be installed inconspicuously, for example, by arranging it together with books on a bookshelf. Moreover, as long as there is an outlet, no wiring work is required. Further, the installation location can be easily changed. If the base station 11 has a shape resembling an object normally present at the entrance (for example, a flowerpot or an umbrella stand), the base station 11 can be installed so as to be inconspicuous at the entrance.
[0045]
Further, the substation 12 can be easily installed because the installation is completed only by directly inserting the substation 12 into an outlet. When the user wakes up for a toilet or the like in the middle of the night, the infrared sensor 12a and the ultrasonic sensor 12b provided in the substation 12 detect the occupant, and the lighting lamp 12c is turned on, so that the foot is guided and the driver can safely travel. It is possible to walk.
[0046]
Further, the glass alarm 13 can detect the breakage of the window by an intruder only by sticking it on the window glass. Further, since the glass alarm 13 is thin, it is possible to pull the window.
[0047]
In addition, the server 2 provided in the management center 2 automatically distributes anomaly information detected by the security device 1 to the mobile phones 3a to 3e of the first to fifth notifiers by e-mail. Unmanned becomes possible. For this reason, the operation cost of the management center 2 is also low.
[0048]
In the above embodiment, the transmission of the abnormality information from the security device 1 to the management center 2 shown in FIG. 1 is performed using the telephone network 100 of the wireless packet communication system. It is also possible to perform transmission using a public telephone line network. In this case, it is possible to use the existing fixed telephone line, and it is not necessary to make a new contract for the use of the telephone line network of the mobile telephone or to incorporate a wireless transmission device. Therefore, the cost required for communication can be reduced. Further, if the server 2 receives the telephone call from the security device 1 and refers to the telephone number of the registrant stored in the database in advance, it is not necessary to prepare a modem in the security device 1, and the security device 1 Can be easier and simpler.
