Description

  The present invention relates to a monitoring system that performs automatic notification from a central processing unit based on an unsteady signal from a terminal device.

  In recent years, the demand for surveillance systems in homes has increased with the increase in theft crimes. Conventionally, this type of monitoring system is composed of a combination of a sensor terminal for detecting an intruder and a central processing unit that issues an alarm. When the central processing unit receives an unsteady state such as occurrence of intrusion from each sensor terminal ( For example, those that automatically notify an outside line telephone of a security company (for which a user has contracted for a security service) and can make a voice call with a central processing unit have begun to spread.

  Also, recently, a monitoring system provided with a simple communication function (home intercom function) between each sensor terminal and the central processing unit has been proposed.

  Here, in this type of surveillance system, the connection destination (report destination) of an outside line telephone is generally a security company, but, on the other hand, a private branch exchange system for telephones for telephone calls (unrelated to the surveillance system) In, when a user of a certain extension leaves the extension and moves to another location, the destination (forwarding destination) is registered, and the incoming call to the extension from then on is automatically transferred to the destination. (For example, refer to Patent Document 1).

  Hereinafter, a configuration of a conventional monitoring system will be described.

  FIG. 23 is a system block diagram of a conventional monitoring system of this type, wherein 1 is a central processing unit, and 2 or 3 is a terminal. Communication between the central processing unit 1 and the terminal 2 or 3 is performed by wireless communication means described later.

  FIG. 25 is an internal block diagram of the terminal 2 or 3. Reference numeral 13 denotes an intrusion detecting means (not shown) provided with an infrared light receiving / emitting unit for detecting an unsteady state in response to a change in the infrared output emitted from 1 to 3 m around the terminal 2 or 3. It is. In other words, by installing this terminal near a window in the house or in the living room, it is possible to detect intrusion into the house from outside as an unsteady state.

  Reference numeral 14 denotes a terminal control unit which wirelessly transmits an unsteady signal from the intrusion detecting means 13, that is, information that an intrusion has occurred, to the central processing unit 1 together with its own terminal code using the data communication means 15. Is what you do. Reference numeral 16 denotes an audio communication unit which communicates an audio signal with the central processing unit 1. Reference numeral 17 denotes an audio output unit for increasing the volume of the audio signal received and demodulated by the audio communication unit 16. Reference numeral 18 denotes a voice input unit, by which voice around the terminal 2 is collected, modulated by the voice communication unit 16 and transmitted to the central processing unit 1.

The operation will be described based on the above configuration. When the user goes out, the setting unit 10 of the central processing unit 1 sets the alert mode, whereby the alert operation starts. During an alert operation, if there is an intrusion into the house from the outside near the window in the house where the terminal 2 or 3 is installed or in the living room, the intrusion detecting means 13 operates, and the data communication means 15 in the terminal 2 or 3 is actuated. As a result, an unsteady state occurrence signal is output. When receiving this signal, the data communication means 15 transmits a signal to the data communication means 5 of the central processing unit 1. This signal first transmits an address code of its own terminal and a status code indicating that an intrusion has occurred. In the central processing unit 1, the data communication means 5 of the central processing unit 1 receives the transmission signal, determines which terminal the signal is from, and further receives a signal indicating that the intrusion has occurred. Based on this signal, the public line connection means 7 operates to establish a communication configuration with the telephone outside the house corresponding to the telephone number registered in advance from the external line connection unit 8. Thus, the voice around the terminal can be monitored by the telephone outside the home through the voice input means 18, and the surrounding situation can be intercepted. When necessary, the intruder is threatened by the voice of the user from the voice output means 17 through the telephone.

  However, in the above-described conventional configuration, if there is an intrusion into the house from the outside during the alerting operation, the central processing unit 1 operates the public line connection means 7 and connects the outside line to the outside telephone having a telephone number registered in advance. In a monitoring system that makes a connection but performs two-way data communication between the central processing unit and the sensor terminal, the function of the central processing unit is based on a control command from a control device of a security company that performs remote monitoring ( For example, there are many functions that depend on the control device of the security company, such as controlling each terminal (such as sounding a buzzer of a terminal that detects intrusion or stopping the buzzer). This is different from the meaning that any other party can make a general call (in the worst case), and the central processing unit simultaneously performs a call with the sensor terminal and an external connection destination (security company) at the same time. Due to technical difficulties, the central processing unit was notified only to one of the (contracted) security companies. If the security company, which is the notification destination, is already on a call, it may be necessary to report the intrusion into the home. Had the problem of not being able to do so.

  SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. In a monitoring system for performing two-way data communication between a sensor terminal and a central processing unit (for example, a telephone call is possible), a destination notified by the central processing unit is provided. It is an object of the present invention to provide a surveillance system in which a plurality of are set and an effective intrusion into the house is provided.

  In order to solve the above-mentioned conventional problem, the monitoring system of the present invention is configured such that when a terminal detects an unsteady state, an external line is sequentially connected to a plurality of notification destinations stored in advance in a storage unit. Things.

  This makes it possible to set a plurality of destinations to be notified in the case of intrusion into the house. If an intruder actually enters the house, even if one destination is already in a call, another destination External line connection is possible.

  In the monitoring system of the present invention, when a terminal detects an unsteady state, an external line is sequentially connected to a plurality of notification destinations stored in advance in a storage unit.

  This makes it possible to set a plurality of destinations to be notified in the case of intrusion into the house. If an intruder actually enters the house, even if one destination is already in a call, another destination External line connection is possible.

  A first invention is a terminal for monitoring a steady or unsteady state and one central processing unit, and transmission of data on the steady state or the unsteady state between the terminal and the central processing unit. And a data communication unit for performing reception, a storage unit for storing a plurality of notification destinations, and an external line connection unit for externally connecting to a communication device of the notification destination, and the central processing unit transmits a signal in an unsteady state from the terminal device. When receiving, the outside line connecting means sequentially connects the outside line to the notification destination registered in advance in the storage means, so that it is possible to set a plurality of destinations to be notified when entering the house, If the intrusion into the home occurs, the central processing unit can make an external line connection to a plurality of notification destinations in order (that is, in the order of registration of the set destination telephone numbers).

  According to a second aspect of the invention, in the monitoring system of the first aspect, the central processing unit repeats the external line connection a predetermined number of times when the external line connection to the notification destination cannot be performed by the external line connection means. By doing this, you can make an external line connection to multiple notification destinations, but if you fail to connect all (due to a reason such as a busy call), you can try to reconnect several times and connect to an external line It is to be.

  According to a third aspect, in the monitoring system according to the first aspect, the central processing unit, when the external line cannot be connected to the notification destination by the external line connection means, connects the external line at a predetermined time interval. Is repeated, even if connection to an outside line is attempted for a plurality of notification destinations, but all connections fail, after a predetermined period of time (for example, 5 minutes after the other party will end the call). A connection is attempted to enable external line connection.

  In a fourth aspect, in the monitoring system according to the first aspect, the central processing unit preferentially gives priority to the busy communication destination when the external connection to the notification destination cannot be performed by the external line connection means. By repeating the outside line connection, that is, it is assumed that there is a person in front of the telephone that is busy. ) To increase the likelihood.

  According to a fifth aspect of the present invention, in the monitoring system of the first to fourth aspects, the central processing unit includes a display unit for displaying a connection state, and the external line connection unit cannot make an external line connection to the notification destination. In the case, by displaying the failure of the external line connection or the fact that the external line connection cannot be performed on the display means, if the external line connection is attempted for the plurality of notification destinations, but all the connection fails, the fact is displayed. This enables the user to confirm the connection failure state.

  In a sixth aspect of the present invention, in the monitoring system according to the first aspect, the central processing unit sets a notification destination for performing an outside line connection with priority among a plurality of notification destinations stored in the storage unit. When a signal in an unsteady state is received from a terminal device, the first priority notification destination setting means sequentially connects an outside line from a priority notification destination. Thus, it is possible to easily change the priority of the notification destination among a plurality of notification destinations.

  According to a seventh aspect of the present invention, in the monitoring system according to the first aspect, the central processing unit preferentially establishes an outside line connection among a plurality of notification destinations stored in the storage means only for a specific terminal. A second priority notification destination setting unit for setting a notification destination to be performed, and when a signal in an unsteady state is received from a specific terminal, an outside line is sequentially set from the priority notification destination by the second priority notification destination setting unit. By connecting, depending on the type of multiple terminals installed in the same house (for example, the notification destination of the intrusion detection terminal is a security company, only the specific nursing terminal It is possible to set the destination to be notified (to the company).

  According to an eighth aspect of the present invention, in the monitoring system of the first aspect, the central processing unit keeps maintaining the external line connection by a predetermined operation of the receiver in the communication device connected to the external line, thereby providing the external line connection. Can be distinguished into those who automatically receive calls, such as answering machines and fax machines, and those who can perform certain operations, so that only the person (person) who wants to be notified is notified of intrusion detection accurately. It is possible.

  In a ninth aspect of the present invention, in the monitoring system according to the eighth aspect, the central processing unit notifies the receiver of a predetermined operation procedure with the communication device connected to the outside line, thereby enabling the externally connected party to communicate. By announcing the operation procedure of the predetermined operation to (a person), it is possible to reliably perform the predetermined operation while ensuring the convenience of the receiver.

  A tenth invention is particularly directed to the monitoring system according to the eighth invention, wherein the central processing unit disconnects the external line connection when the receiver does not perform a predetermined operation within a predetermined time in the communication device connected to the external line, In addition, since the outside line is sequentially connected to the notification destination registered in advance in the storage means, when the externally connected party is a device such as an answering machine or a facsimile that automatically receives a call, unnecessary outside line connection is performed. It stops immediately and allows an external line to be immediately connected to the next notification destination.

  An eleventh invention is a program for causing a computer to realize at least one of the functions of the monitoring system according to any one of the first to tenth inventions. According to this configuration, when the terminal device detects an unsteady state (intrusion into the house), the monitoring system can sequentially connect the external line to the plurality of notification destinations registered in the storage unit using the external line connection unit. It is to be. In addition, since the program is a program, at least a part of the monitoring system of the present invention can be easily realized by cooperating hardware resources such as an electric / information device, a computer, and a server. Further, by recording the program on a recording medium or distributing the program using a communication line, the program can be easily distributed / updated and installed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited by the embodiment. The same components as those in the background art are denoted by the same reference numerals, and description thereof is omitted.

(Embodiment 1)
FIG. 1 is a system block diagram of a monitoring system according to the first embodiment, FIG. 2 is an internal block diagram of a central processing unit according to the first embodiment of the present invention, and FIG. 3 is a terminal according to the first embodiment of the present invention. FIG. 4 is a flowchart showing the operation of the main part of the central processing unit 19. The storage unit 21 in FIG. 2 stores a plurality of notification destinations, and specifically stores the telephone numbers of the notification destinations input by the setting unit 10. In the present embodiment, two notification destinations are stored in the storage unit 21 in advance, and the notification destination stored as the first notification destination is stored as the notification destination 1 and the second notification destination. The notified notification destination is referred to as notification destination 2. Otherwise, the configuration is the same as that of the conventional example except for the central processing unit 19 and the control means 20.

  The operation and operation of the monitoring system configured as described above will be described below.

  When the alerting operation is started, as shown in the flowchart of FIG. 4, when the terminal device 2 or the terminal device 3 detects the intrusion in S1, a notification (which is the first notification destination) from the storage unit 21 in S2. The telephone number of the destination 1 is called, and a call is made to the notification destination 1 by the public line connection means 7 in S3 (call is made).

  If the call cannot be made to the notification destination 1 in S4, the telephone number of the notification destination 2 (which is the second notification destination) is called from the storage means 21 in S5, and notified by the public line connection means 7 in S6. Make a call to destination 2.

  In S4 and S7, when the external line connection to either the notification destination 1 or the notification destination 2 succeeds (when the telephone is connected), the alert operation process ends while maintaining the external line connection at that time. On the other hand, in S4 and S7, when both the notification destination 1 and the notification destination 2 fail to connect to the outside line, the alert operation process ends abnormally.

  As described above, in the present embodiment, when the terminal detects an unsteady state (intrusion into the house), it is possible to set a plurality of destinations to be notified. And the notification destination 2 is set to a security company (previously subscribed to a security service), and the central processing unit 19 receives an unsteady state from a terminal (at home) when going out. In such a case, the central processing unit 19 first makes a call to the user's mobile phone, which is the notification destination 1, and the user intercepts the situation in the house by telephone and checks whether or not an abnormality has occurred in the house. On the other hand, if the mobile phone cannot be connected to the user's mobile phone due to radio waves or the like, the central processing unit 19 can call the security company of the notification destination 2.

  In recent years, the performance of terminals has improved, such as intrusion detection, but false alarms in various usage environments (for example, false alarms of fire alarms) are hardly unusual. Instead of notifying the security company, the first notification is sent to the user who is a family member, and the aim is for the user to check the status of the house at the voice call level, while the user is not connected to the telephone In this case, the security company is notified, and when the central processing unit is connected to a dedicated terminal of the security company via an external line, in addition to checking the status of the house at the voice call level, the buzzer or sound of each terminal via the central processing unit Control, such as stopping).

  As described above, when the terminal in the home detects an abnormal situation, the potential demand for making a step-by-step report to the user using the first report to the security company as a backup is increasing in the market. From this point of view, the effectiveness of the present embodiment is high.

  In the present embodiment, the number of notification destinations is specifically set to two, but the number of settings is not particularly limited.

  Further, in the present embodiment, the means for talking to outside the home is described using a telephone or a public line, but the present invention is not limited to this, and may be a communication device such as a personal computer or a portable information terminal, or a dedicated line or an Internet line. It may be.

FIG. 5 is an internal block diagram of the central processing unit according to the second embodiment of the present invention, and FIG. 6 is a flowchart showing an operation of a main part of the central processing unit 19. As shown in FIG. 5, the configuration other than the control device 22 is the same as that of the first embodiment.

  The operation and operation of the monitoring system configured as described above will be described below.

  When the alerting operation is started, as shown in the flowchart of FIG. 6, when the terminal 2 or 3 detects intrusion in S1, the number of telephone calls is cleared in S8. Steps S2 to S8 are the same as those in the first embodiment, and a description thereof will be omitted. However, in S4 and S7, when both the notification destination 1 and the notification destination 2 have failed in the external line connection (call to any of the notification destinations ), One is added to the number of telephone calls in S9, and if the number of telephone calls is less than five in S10, S2 to S8 are repeated.

  As described above, in the present embodiment, when the terminal device detects an unsteady state (intrusion into the house), the terminal repeatedly makes a call to a plurality of destinations to be notified a predetermined number of times. Even if the telephone is a mobile phone and the central processing unit 19 fails to connect to an external telephone (for example, when the owner of the mobile phone is The processing device 19 can make an external line connection by repeatedly making a call to the called party.

  In the present embodiment, the limit of the number of telephone calls (the number of repeated calls) is specifically shown as five, but this number is not limited, and the user can set it freely. It may be configured.

(Embodiment 3)
FIG. 7 is an internal block diagram of the central processing unit according to the third embodiment, and FIG. 8 is a flowchart showing an operation of a main part of the central processing unit 19. As shown in FIG. 7, the configuration other than the control device 23 is the same as that of the first embodiment.

  The operation and operation of the monitoring system configured as described above will be described below.

  As shown in the flowchart of FIG. 8, the processing added to the second embodiment is only S11. That is, in S4 and S7, when both the notification destination 1 and the notification destination 2 have failed in the external line connection (in either case). If no call is made to the notification destination), one is added to the number of telephone calls in S9, and if the number of telephone calls is less than 5 in S10, a 5-minute interval is set in S11 at S2. S8 is repeated.

  As described above, in the present embodiment, when the terminal device detects an unsteady state (intrusion into the house), it repeatedly calls the destinations to be notified after a predetermined time elapses. Even if the other party is busy, the central processing unit 19 can make an external line connection by making a call at a predetermined time interval (the other party will end the call).

  In the present embodiment, the interval between the failure of the external line connection and the next attempt of the external line connection is specifically shown as 5 minutes. However, this time is not limited, and the user is not required. The configuration may be set freely.

  The operation and operation of the monitoring system configured as described above will be described below.

  As shown in the flowchart of FIG. 10, the processes added to the first embodiment are only S12 and S13. Here, when S4 and S7 are supplemented, these S4 and S7 are added to the destination 1 or the destination 2. After starting the telephone call (calling process), the user waits for an on-hook state (the handset of the external telephone being called is raised by the called party) for only 30 seconds, but within 30 seconds after the telephone call If the on-hook is not performed (time-up), or if a busy tone sound (pull, repeat of the pull) is detected, it is determined that the external line connection processing has failed. We know whether the cause is due to time up or busy.

  Returning to the description, in S4 and S7 of the flowchart, if both the called party 1 and the called party 2 fail to connect to the outside line (if no call is made to any of the called parties), the outside line connection is established in S12 and S13. A process for making a call again to the other party who was busy for the cause of the failure is performed.

  As described above, in the present embodiment, an external line connection is attempted for a plurality of set destinations, but if all connections fail, the external line connection is preferentially repeated for a busy destination. In other words, since it is assumed that a person is in front of the telephone that is busy, the possibility of an outside line connection (calling the telephone) is increased by giving priority to the call destination again. Things.

As shown in FIG. 13, the first priority notification destination setting unit 27 sets a notification destination for performing an outside line connection with priority among a plurality of notification destinations stored in the storage unit 21. Except for the control device 26, the configuration is the same as that of the first embodiment.

  The operation and operation of the monitoring system configured as described above will be described below.

  As shown in the flowchart of FIG. 14, the processes added to the above-described second embodiment are S15 and S16. That is, when the alert operation is started, if the terminal device 2 or 3 detects intrusion in S1, ( In S15, after the number of telephone calls is cleared in S8, the priority notification destination (priority notification destination) among the notification destinations stored in the storage means 21 is read from the first priority notification destination setting means 27, If the priority notification destination is the notification destination 2 in S16 (skipping the external line connection processing to the notification destination 1 in S2 to S4), an external line connection to the notification destination 2 is performed in S5 to S7.

  In the example of the flowchart, an example in which only two notification destinations are registered has been described. However, in practice, four or more notification destinations are often set. Specifically, four notification destinations are registered in the registration order. When the notification destinations to be notified with priority are set to the notification destinations 3 as the notification destination 1, the notification destination 2, the notification destination 3, and the notification destination 4, the connection order is the notification destination 3 (which is the priority connection destination), After that, according to the order of registration), notification destination 1, notification destination 2, notification destination 3, and notification destination 4 are in that order.

  As described above, in the present embodiment, it is possible to set a notification destination to which a notification is to be given with particular priority among a plurality of notification destinations stored in the storage means. If the user wants to report to 1 (the landline telephone of the employer of the user), but knows in advance that no one will respond to the call to the notification destination 1 due to circumstances (such as a holiday), the first By setting the priority notification destination of the priority notification destination setting means to the notification destination 2 (user's mobile phone), it is possible to make a call from the notification destination 2 without unnecessarily making an external line connection to the notification destination 1.

  In this embodiment, an example in which the priority notification destination is manually set has been described. However, the priority notification destination may be changed according to the time zone or the day of the week.

FIG. 15 is an internal block diagram of a central processing unit according to the seventh embodiment of the present invention, and FIG. 16 is a flowchart showing an operation of a main part of the central processing unit 19. As shown in FIG. 15, the second priority notification destination setting means 29 sets a notification destination for performing an outside line connection with priority to a specific terminal device among a plurality of notification destinations stored in the storage means 21. It is. Except for the control device 28, the configuration is the same as that of the first embodiment.

  The operation and operation of the monitoring system configured as described above will be described below.

  As shown in the flowchart of FIG. 16, the difference from the sixth embodiment is S17 to S19. That is, when the alerting operation is started, if the terminal 2 or 3 detects intrusion in S1, (S8 In step S17, after the number of telephone calls is cleared in step S17, a notification destination (priority notification) that is given priority to a specific terminal from the notification destinations stored in the storage unit 21 from the second priority notification destination setting unit 29 ) Is read, and in S18 (in this embodiment, a specific terminal is registered as the terminal 2 in advance), when it is determined that the intrusion is detected from the specific terminal, priority is given in S19. When the notification destination is the notification destination 2 (skipping the external line connection processing to the notification destination 1 in S2 to S4), an external line connection to the notification destination 2 is performed in S5 to S7.

  As described above, in the present embodiment, among the plurality of notification destinations stored in the storage unit, only a non-stationary detection from a specific terminal device is notified to the specific notification destination. In the case where most of the multiple terminals are intrusion detection terminals installed for intrusion purposes and only one (specific terminal) terminal is a terminal for elderly care, intrusion detection By setting the notification destination (that is, notification destination 1) of the service terminal to the security company, and setting the notification destination (that is, notification destination 2) of the specific nursing care terminal only to the nursing care service company, the notification destination according to the purpose can be accurately determined. Can be notified.

  The operation and operation of the monitoring system configured as described above will be described below.

  As shown in the flowchart of FIG. 18, the difference from the above-described second embodiment is the processing in the case where the outside line connection is successful in S4 and S8 (the telephone is connected to the notification destination). Note that the processing in the case where both the notification destination 1 and the notification destination 2 successfully connect to the outside line is the same, and therefore, in the present embodiment, only the processing in the case where the external connection of the notification destination 1 succeeds will be described.

  If the outside line connection to the notification destination 1 succeeds in S4, the operation button (the push button for inputting a telephone number in the case of a telephone) on the operation unit of the communication terminal of the notification destination is pressed in S20 (not shown). In this case, the external line connection is continued only when the button pressed in step S21 is the "#" button. On the other hand, when a button other than the "#" button is pressed, the central processing unit 19 in step S22. Unilaterally cut off the outside line connection.

  As described above, in the present embodiment, the user performs a predetermined operation at the communication device of the notification destination to which the external line has been connected, so that only the other party performing the predetermined operation keeps maintaining the external line connection. Yes, this makes it possible to distinguish externally connected parties into devices that automatically receive calls, such as answering machines and fax machines, and those who can perform predetermined operations. It is possible to narrow down and notify intrusion detection accurately.

  In the present embodiment, it has been described that the external line connection is continued with the “#” button, but other button operations may be performed.
