Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a security system built on a security object that is a target of security, and in particular, only a predetermined part of the security sensors arranged in the security object is set in the alert state. The present invention relates to a security system including a home security mode in which other security sensors are set to a release state and / or a security mode in which all security sensors are set to a security state.
[0002]
[Prior art]
Various security modes are provided in a security system constructed in a security property. As the security mode, there is a security mode called a home security mode or a home security mode. In this specification, this mode will be referred to as home alert mode. There is also a security mode called a security mode.
[0003]
The home security mode is a security mode in which only a predetermined number of security sensors among security sensors arranged in a security property are in a security state, and other security sensors are in a release state. This is a security mode widely used in a home security system constructed in a large-scale office or the like (for example, see Patent Literature 1, Patent Literature 2, and Patent Literature 3).
[0004]
The home alert mode is mainly set during bedtime, but may be set even during the day when a specific room becomes unoccupied. In the home security mode, when an alarm signal is output from the security sensor set to the alert state, it is immediately determined that an abnormality has occurred, the intimidating device is operated, and the telephone number registered in advance is used. Is reported to
[0005]
The security mode is a security mode in which all the security sensors arranged in the security property are in a security state, and is set when the security property is unmanned. In the alert mode, when an alarm signal is output from any one of the security sensors, it is immediately determined that an abnormality has occurred, the intimidating device is operated, and a notification is sent to a telephone number registered in advance. Done.
[0006]
As the security sensor, a heat ray sensor that detects the movement of a person, an open / close detection sensor that detects that a window or a door is opened, and the like are widely used indoors. An infrared beam sensor or the like in which a light projecting means for projecting light and a light receiving means for receiving infrared light are paired is used.
[0007]
Further, the alarm signal refers to a signal output when the security sensor detects a predetermined state, for example, the hot-wire sensor outputs an alarm signal when detecting a state that a person has moved, The open / close detection sensor outputs an alarm signal when it detects that the window or door is open, and the infrared beam sensor emits an alarm when it detects that the infrared light emitted from the light emitting means is blocked. Output a signal.
[0008]
As the intimidating device, an intimidating device using a sound such as a siren or a buzzer or an intimidating device using a light such as a floodlight is used.
[0009]
In addition, there are various methods for how to make a report. If security is outsourced to a security company, data indicating that an abnormality has occurred is sent to the security center equipment of the security company. Is transmitted via a public telephone line or an appropriate network such as the Internet.
[0010]
When notifying security to a security company, but notifying a specific individual that an abnormality has occurred, use a speech synthesis technology to notify the occurrence of the abnormality by voice to a telephone number registered in advance. A so-called voice report is performed (for a voice report, for example, see Patent Document 4). Further, it is naturally possible to report to a specific personal digital assistant (PDA) by e-mail or packet communication.

[0012]
[Problems to be solved by the invention]
As described above, the home security mode is a security mode that is widely adopted in a home security system in which a private house is a security property. When the alarm signal is output, it is immediately determined that an abnormality has occurred, so that a person at home or a customer accidentally enters the monitoring area of the hot-wire sensor set to be alert, and It is also determined that an abnormality has occurred when a warning signal is output or a warning signal is output from the open / closed detection sensor when the window or door where the open / closed detection sensor set to be alert is opened and the open / closed detection sensor is opened. As a result, there has been a problem that a threatening device such as a siren is operated to cause trouble in a neighborhood.
[0013]
In that case, an abnormality report will also be made, and the person who received the report will rush in or make a phone call to confirm, etc., which is also annoying for the person who received the report. There is also a problem that it will.
[0014]
As described above, in the related art, in the home alert mode, misinformation often occurs due to the behavior of a person other than an intruder such as a house or a guest.
[0015]
The case of the home security mode has been described above. However, the above problem is not limited to the home security mode but may occur in the security mode. That is, when the guardian returns in a state where the alert mode is set, the alert mode is not canceled and the user accidentally enters the monitoring area of the heat ray sensor, or the window or door where the open / close detection sensor is arranged. It may be possible that the security sensor will be triggered by opening the door, but in this case too, it is immediately determined that an abnormality has occurred, and a threatening device such as a siren will be activated to disturb the neighborhood. It will cause trouble and inconvenience the person who receives the report.
[0016]
As one countermeasure in such a case, it is conceivable to stop the operation of the intimidating device and provide a switch for stopping the notification in the security device that performs security processing. In this manner, in the home alert mode or the alert mode, if a occupant mistakenly alerts the security sensor located in the alert area in the alert state, the threat is activated by operating the switch. It is possible to stop the operation of the device and prevent the notification from being made.
[0017]
However, since such a switch is provided in an easily visible place, if the intruder has issued the security sensor, the intruder operates the switch and operates the intimidation device. It is also possible to stop the operation of and stop reporting.
[0018]
Therefore, the present invention provides a security that can stop the operation of the threatening device and stop the report in a manner that is difficult for an intruder to understand, when an abnormality occurs due to the action of a person other than the intruder. It is intended to provide a system.
[0019]
[Means for Solving the Problems]
In order to achieve the above object, the security system according to claim 1 includes a security sensor, a threatening means, a telephone, and only a predetermined part of the security sensors among the security sensors in a security state. Control means having at least a home security mode in which the security sensor is in a release state and / or a security mode in which all security sensors are in a security state, and a line switching means for connecting the office line to the control means and / or the telephone And, a security system comprising at least voice synthesis means, the control means, in a state where the home security mode or the security mode is set, when receiving a signal from the security sensor in the security state, Initiates abnormal delay operation, activates the threatening means in a predetermined form, and then detects that the telephone handset is off-hook within a predetermined operation delay time In this case, the control unit controls the line switching unit, connects at least the control unit to the telephone, outputs a guidance message for guiding the operation by the voice synthesizing unit, and then inputs the ID number registered in advance from the telephone. Only when this is the case, the home alert mode or the alert mode is canceled, the operation of the threatening means is stopped, and an operation for not issuing an abnormality report is performed.
According to a second aspect of the present invention, in the security system according to the first aspect, when the predetermined operation delay time elapses without starting a telephone receiver off-hook after the start of the abnormal delay operation, the control unit notifies the abnormality. Is performed.
4. The security system according to claim 3, wherein the control unit registers the ID number input from the telephone beforehand even after the abnormal delay operation is started and the telephone receiver is off-hook within the operation delay time. When the ID number is different from the ID number, an abnormality notification is performed.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a security system according to the present invention. In the figure, reference numeral 1 denotes a control unit, 2 denotes a terminal interface (hereinafter, referred to as a terminal I / F), 3 denotes a security mode setting unit, 4 is a threatening means, 5 is a voice synthesizing means, 6 is a communication control means, 7 is a coupling circuit, 8 is a line switching means, 9 is a telephone, and 10 is a receiver state detecting means.
[0021]
Hereinafter, each part of the configuration shown in FIG. 1 will be schematically described.
The control means 1 performs a security process including an abnormality notification. Here, it is assumed that three security modes are provided as the security mode: a home security mode, a security mode, and a release mode. In the control means 1, a telephone number of a report destination and a predetermined ID number are registered. Details of the operation of the control means 1 will be described later.
[0022]
It should be noted that a plurality of telephone numbers of the report destination may be registered. When outsourcing security to a security company, the phone number of the security company's security center device may be registered as the report destination, and in addition, the number of the mobile phone of the owner of the security property or an abnormality has occurred. In such a case, a mobile phone number or the like of a person who can come immediately may be registered. If security is not entrusted to the security company, the mobile phone number of the owner of the security property, or the mobile phone number of a person who can immediately come in the event of an abnormality should be registered. Then, when registering a plurality of telephone numbers of report destinations, a priority order indicating the order of the report may be set for each telephone number.
[0023]
The terminal I / F2 has a plurality of input channels, and a security sensor is connected to the input channels. As described above, the security sensor includes a heat ray sensor, an opening / closing detection sensor, an infrared beam sensor, and the like.
Then, when receiving the alarm signal from the security sensor connected to a certain input channel, the terminal I / F 2 notifies the control unit 1 of the input channel from which the alarm signal was output.
[0024]
The security mode setting means 3 is for setting the security mode for the control means 1, and here, as shown in FIG. 2, the home security button 11 for setting the home security mode, and setting the release mode. And a warning button 13 for setting a warning mode.
[0025]
As described above, the home security mode is a security mode in which only a predetermined part of the security sensors among the security sensors is in a security state, and other security sensors are in a release state, and the home security button 11 is operated. In the state where the home alert mode is set, the control unit 1 previously registers which input channel of the terminal I / F 2 determines that an abnormality has occurred when the alarm signal is received from the security sensor. .
[0026]
As described above, the security mode is a security mode that is set when all members of the house go out and the inside of the security property becomes unmanned. In this security mode, the control unit 1 controls all input channels of the terminal I / F 2. Is valid. That is, all the security sensors are set in the alert state.
[0027]
The release mode is a security mode in which security is not performed on all monitoring areas. In this release mode, the control unit 1 ignores alarm signals from all input channels of the terminal I / F2.
[0028]
The intimidating means 4 is for intimidating an intruder. The intimidating means 4 may be only an intimidating means by a sound such as a siren or a buzzer. And a device that performs light threats may be provided. Although only one intimidating means 4 is shown in FIG. 1, this is a convenient measure only to avoid complicating the figure. There are many. In short, at least one threatening means 4 is provided.
[0029]
The voice synthesizing means 5 is for providing predetermined guidance to the telephone 9 by voice as described later. Since the method of speech synthesis and its configuration are well known, description thereof will be omitted. The voice synthesizing means 5 is also used when reporting the abnormality notification by voice.
[0030]
The communication control means 6 performs processing relating to telephone calls, such as dialing to a report destination when an abnormality report is made, closing a line, and opening a line. Since such communication control means 6 is well known, description thereof will be omitted.
[0031]
The coupling circuit 7 is for transformer-connecting the communication control means 6 and the line switching means 8.
Under the control of the control unit 1, the line switching unit 8 switches between connecting the office line to the control unit 1 via the communication control unit 6 or connecting to the telephone set 9. Although various configurations of the line switching means 8 are conceivable, here, a configuration using four relays R1 to R4 is used as shown in FIG. Although the operation of the line switching means 8 will be described later, FIG. 3 shows a state of the line switching means 8 in a normal state, that is, in a state where no abnormality has occurred, in which COM is a common terminal and NO is a normal terminal. An open terminal and NC indicate a normally closed terminal. Hereinafter, they are simply described as COM, NC, and NO.
[0032]
The telephone 9 is a stationary telephone, and here, a telephone that emits a push button type PB tone is used. In addition, the telephone 9 may be one that can use a cordless handset.
The office lines in the figure are connected to the nearest exchange.
[0033]
The receiver state detecting means 10 is for the control means 1 to detect the state of the receiver of the telephone 9, that is, whether the receiver is off-hook or on-hook. There are various known methods for detecting whether or not the receiver is off-hook. For example, a method of monitoring a voltage between two office lines or a method of monitoring the polarity of an office line is widely known. However, any method may be used here. Further, other known methods may be used.
[0034]
Then, the control means 1 monitors the state of the local line by the receiver state detecting means 10, and determines that the telephone set of the telephone 9 is off-hook when the state of the central line becomes a predetermined state. For example, assuming that a method of monitoring the voltage between two office lines is used as the receiver state detection means 10, the control means 1 will control the telephone 9 if the telephone line voltage is 48V by the receiver state detection means 10. The receiver is determined to be on-hook, and if the line-to-station voltage is 10 V, it is determined to be off-hook.
[0035]
Hereinafter, the operation will be described.
[Operation in release mode]
When the release button 12 of the security mode setting means 3 is operated, the control means 1 enters the operation of the release mode.
[0036]
An alarm signal is output from the security sensor even in the release mode. That is, the hot-wire sensor outputs an alarm signal when detecting the movement of a person, and the open / close detection sensor outputs an alarm signal when the window or door to which it is attached is opened. However, in the release mode, the control means 1 ignores any alarm signal from any security sensor and does not judge that an abnormality has occurred. That is, no security is performed in the release mode.
.
[0037]
In the release mode, the control means 1 ignores the fact that the handset of the telephone 9 is off-hook by the handset state detection means 10 and does not control the line switching means 8 at all. Therefore, at this time, the line switching means 8 is in the state shown in FIG.
[0038]
[Operation in home alert mode]
When the home security button 11 of the security mode setting unit 3 is operated, the control unit 1 starts operation in the home security mode. As described above, the input channel of the security sensor to be in the alert state in the home alert mode is registered in the control means 1 in advance.
[0039]
When receiving the alarm signal from the security sensor in the home security mode, the control unit 1 determines whether the security sensor is in the alert state or in the released state, and determines whether the security sensor is in the released state. Ignores the alarm signal, does not judge that an abnormality has occurred, does not operate the threatening means 4, and does not report.
[0040]
At this time, the control means 1 ignores the fact that the handset of the telephone 9 is off-hook by the handset state detecting means 10 and does not control the line switching means 8 at all. Therefore, at this time, the line switching means 8 is in the state shown in FIG.
[0041]
However, when the security sensor that has output the alarm signal is in the alert state, the control unit 1 determines that there is a possibility of occurrence of an abnormality, and starts an abnormal delay operation. In this abnormal delay operation, the control means 1 causes all the threatening means 4 to operate in a predetermined first mode. No report is made at this time.
[0042]
Here, the operation of the first mode of the intimidating means 4 is an operating mode for notifying a home resident that the control means 1 is performing an abnormally delayed operation, and threatens an intruder, This is different from the second mode for notifying the occurrence of an abnormality. For example, assuming that the intimidating means 4 performs intimidation by sound and that the operation of the second mode is continuous sounding, in the first mode, the sound is intermittently sounded at a predetermined cycle. Just fine. Further, if the intimidating means 4 performs intimidation by light, and if the operation of the second aspect is continuous light emission, in the first aspect, light is emitted intermittently at a predetermined cycle. What should I do? Such an operation of the first aspect is unlikely to bother the neighborhood.
[0043]
As described above, in the home alert mode, even if an alarm signal is received from a security sensor that has been alerted, the alert is not immediately sent, and the abnormal delay operation is performed as described above. At the time of the mode, it may happen that a security sensor that a family member or a customer is mistakenly alerted is alerted, but in this case no abnormality has occurred, so the family member who is at home On the other hand, it is desirable to allow time for performing an operation for canceling the home security mode.
[0044]
The time for performing the abnormal delay operation is set in the control means 1 in advance, and this time is referred to as an operation delay time in this specification.
[0045]
Therefore, during the abnormal delay operation, it is necessary to notify the family that the abnormal delay operation is being performed by some means. In this security system, all the threatening means 4 are operated in the first mode. By operating, the fact that the abnormal delay operation is being performed is informed, and the family member can know that the abnormal delay operation is being performed by operating the threatening means 4 in the first mode. .
[0046]
When the control unit 1 starts the abnormal delay operation, the control unit 1 operates the threatening unit 4 in the first mode and invalidates the function of the release button 12. Therefore, even if the operation of the threatening means 4 is stopped during the abnormal delay operation and the release button 12 is operated to prevent the notification from being made, the control means 1 still continues the abnormal delay operation.
[0047]
When the control unit 1 performs the abnormal delay operation, the operation for canceling the home security mode is as follows. When the abnormal delay operation is started, the control means 1 waits until the receiver of the telephone 9 is turned off-hook by the receiver state detecting means 10.
[0048]
Then, when detecting that the receiver is off-hook, the control means 1 connects the COMs of the relays R1 and R2 of the line switching means 8 to the NO side as shown in FIG. The relays R3 and R4 remain as shown in FIG. Thereby, the control means 1 can talk with the telephone 9 via the communication control means 6. At this time, the COM of the relays R3 and R4 of the line switching means 8 may be set to the NO side. However, in this case, the telephone 9 is disconnected from the central office, and no voltage is supplied from the nearest exchange. Then, the COMs of the relays R3 and R4 are kept on the NC side.
[0049]
When the line switching means 8 is in the state shown in FIG. 4, the control means 1 controls the voice synthesizing means 5 to cancel the home security mode such as "enter an ID number when stopping the report." To send a guidance message for
[0050]
This guidance message reaches the handset of the telephone 9 via the communication control means 6, the coupling circuit 7, and the line switching means 8, so that the person who took the handset off-hook can recognize the guidance message. Since the receiver is off-hook at this time, a tone of 400 Hz can be heard from the receiver, but it is possible to hear the guidance message.
[0051]
Then, when the home alert mode is canceled and the notification is stopped, and the operation of the threatening means 4 operating in the first mode is stopped, the information is registered in the control means 1 in advance by a push button of the telephone 9. The entered ID number is input. The input ID number is sent to the control means 1 via the line switching means 8, the coupling circuit 7 and the communication control means 6, and also sent to the nearest exchange via the office line.
[0052]
The control means 1 determines whether or not the input ID number matches a pre-registered ID number. If it determines that the input ID number matches, the abnormal delay operation is stopped and the threatening means is stopped. 4 is stopped, the home alert mode is released, the mode is shifted to the release mode, and the line switching means 8 is controlled to set the COM of the two relays R3 and R4 to the NO side as shown in FIG. Switch. At this time, the control means 1 does not perform the abnormality notification.
[0053]
When the line switching means 8 enters the connection state shown in FIG. 5, the office line is released. The reason that the office line is released in this way is that the input ID number is also sent to the exchange, so if the state of FIG. 4 is left as it is, the input ID number matches some telephone number. If the ID number is not a telephone number, the switch sends a well-known voice message saying "This number is not used." This is because, in any case, an undesirable situation occurs.
[0054]
Then, when the control means 1 switches the line switching means 8 as shown in FIG. 5, the control means 1 controls the voice synthesizing means 5 so that the home security such as "cancel the home security mode. Stop the report." Release the mode and send a voice message indicating that the notification is stopped.
[0055]
After this voice message, at this time, the person who goes off-hook of the telephone set of the telephone set 9 goes on-hook. The line switching means 8 is controlled to return to the connection state shown in FIG. As a result, the telephone 9 is connected to the office line.
[0056]
In the above description, the telephone 9 is used. However, if there is a cordless handset, the above operation can be performed using the handset.
[0057]
The above is a description of the case where the predetermined operation is performed correctly while the control means 1 performs the abnormal delay operation. However, if the handset of the telephone 9 is not off-hook within the operation delay time, the abnormal operation is performed. When the operation delay time has elapsed since the start of the delay operation, and during the operation delay time, the handset of the telephone 9 was off-hook, but the input ID number is different from the ID number registered in the control means 1. If it is determined that the input ID number is different from the registered ID number, the control means 1 determines that an abnormality has occurred and operates the threatening means 4 in the second mode. At the same time, an abnormality report is made. The operation of the second mode is as described above, whereby the intruder can be intimidated and the neighborhood can be notified that an abnormality has occurred.
[0058]
The operation in the case of performing the abnormality notification is as follows.
In this case, the connection state of the line switching means 8 is in the state shown in FIG. 3 or the state shown in FIG. That is, when the handset of the telephone 9 is not off-hook within the operation delay time, the state is as shown in FIG. 3. The receiver of the telephone 9 is off-hook within the operation delay time, but the input ID number is determined by the control means. If it is different from the ID number registered in No. 1, it is in the state shown in FIG.
[0059]
In any case, the control unit 1 controls the line switching unit 8 so that the control unit 1 is connected to the central office via the communication control unit 6 as shown in FIG. Switch to disconnect. To switch from the state of FIG. 3 to the state of FIG. 6, the COM of the two relays R3 and R4 of the line switching means 8 is switched to the NO side, and from the state of FIG. The COM of the two relays R1 and R2 may be switched to the NC side, and the COM of the two relays R3 and R4 may be switched to the NO side. By performing such switching, it is possible to open the office line once and then connect to the control unit 1 via the communication control unit 6.
[0060]
Now, when the line switching unit 8 is set to the state shown in FIG. 6, the control unit 1 passes the telephone number of the report destination registered in advance to the communication control unit 6 to make a call. Then, after that, when a notification indicating that the office line is closed is received from the communication control means 6, an abnormality notification is made via the communication control means 6.
[0061]
It is natural that the form of the signal transmitted in the abnormality report is a form in which the report destination can recognize the meaning of the report. For example, when the report destination is a center device of a security company, transmission of code data indicating abnormality is not performed. If it is requested, the code data indicating the occurrence of the abnormality may be transmitted in a form recognizable by the center device. If the report destination is a telephone, the voice synthesizing means 5 is activated to make a voice report. Just do it. However, in any case, the form in which the abnormality notification is performed is not an essential matter in the present invention, and a detailed description thereof will be omitted.
[0062]
In the above description, the operation delay time is preferably, for example, about 30 seconds to 1 minute. That is, the alarm from the security sensor at this time may be caused by the behavior of a family member or a customer, but may also be an intruder, and if the operation delay time is too long, the behavior of the intruder is reduced accordingly. Forgiveness will be forgiven.
[0063]
In the above description, the threatening means 1 is operated in the first mode during the abnormal delay operation, and is operated in the second mode when it is determined that an abnormality has occurred. It is not an essential requirement that the mode of operation of the threatening means 4 be different from that in the case where it is determined that an abnormality has occurred, and the mode of operation of the threatening means 4 may be the same in both cases.
[0064]
[Operation in alert mode]
Next, the operation in the alert mode will be described.
When the security button 13 of the security mode setting means 3 is operated, the control means 1 enters a security mode operation.
[0065]
When the alarm signal is received from the security sensor in the security mode, the control unit 1 performs the same operation as the operation when the alarm signal is received from the security sensor in the alert state in the home security mode described above. . That is, in this case, the abnormal delay operation is started.
[0066]
When an alarm signal is received from the security sensor during the alert mode, the alarm from the security sensor may be caused by an intruder, and it may be immediately determined that an abnormality has occurred. In the security mode, the security sensor is triggered by a person returning home and accidentally entering the monitoring area of the heat ray sensor or opening the window or door where the open / close detection sensor is located without canceling the security mode. In this security system, the control means 1 can generate an abnormality without immediately determining that an abnormality has occurred even when receiving an alarm signal from the security sensor in the alert mode. Therefore, it is determined that there is a possibility that the abnormal delay operation is started.
[0067]
Then, as described above, when the control unit 1 is performing the abnormal delay operation, the release button 12 is invalidated, so that the warning mode is released and the threatening unit 4 operating in the first mode is released. In order to stop the operation and prevent the abnormality notification from being performed, it is necessary to off-hook the handset of the telephone 9 during the abnormal delay operation and to input the ID number registered in the control means 1 by a push button. is there.
[0068]
Also, as described above, if the handset of the telephone 9 is not off-hook within the operation delay time, when the operation delay time has elapsed since the start of the abnormal delay operation, If the handset No. 9 is off-hook but the input ID number is different from the ID number registered in the control means 1, it is determined that the input ID number is different from the registered ID number At this point, the control means 1 determines that an abnormality has occurred, operates the intimidating means 4 in the second mode, and reports an abnormality.
[0069]
The other operations after the start of the abnormal delay operation are the same as the operations performed when a warning signal is received from the security sensor that has been alerted in the home alert mode, and thus the description thereof is omitted.
[0070]
Before the abnormal delay operation is started, the home security button 11 and the release button 12 are enabled, so that if the home security button 11 is operated, the security mode is switched from the security mode to the home security mode. By operating the release button 12, it is possible to switch from the alert mode to the release mode.
[0071]
As described above, in this security system, after the abnormal delay operation is started, if the operation of off-hook of the telephone set of the telephone 9 and inputting the predetermined ID number is not performed, the home security mode or the security mode is released. Since the notification cannot be stopped and the operation of the threatening means 4 cannot be stopped, the operation can be easily performed by a family member, and it is very difficult for an intruder to understand.
[0072]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said Embodiment, A various deformation | transformation is possible. For example, in the above description, the input of the ID number is performed by the push button of the telephone 9. However, the ID number may be input by voice from the receiver using a voice recognition technique.
