Description

  The present invention provides a monitoring system for monitoring using infrared rays, detecting a disconnection for a certain period of time on the receiving side and issuing an alarm, and notifying the detected alarm to a pre-registered party via a communication network It is about.

  Conventional crime prevention systems using infrared rays include those disclosed in Patent Document 1 below, for example. That is, as shown in FIG. 11, the monitoring control device 120 receives an infrared signal emitted from the infrared sensor 111 in the alert area 110. When the reception of the infrared signal is cut off for a predetermined time or longer, the monitoring control device 120 displays the reception console 131 of the security company registered in advance via the telephone network 130, the form terminal 132 possessed by the security officer, or the security request. The person's mobile phone 133 is called and the alarm is notified to the security personnel.

  Many of the security systems using infrared rays are installed as a large-scale system by a security company such as a surveillance camera, and the cost is not small.

  A cordless telephone device for installing a crime prevention system using infrared rays easily and inexpensively is disclosed, for example, in Patent Document 2 below.

  In this technology, as shown in FIG. 12, a slave unit 210 and a master unit 220 that constitute a cordless telephone device are provided. The subunit | mobile_unit 210 has the infrared rays light emission part 211, and the main | base station 220 has the infrared rays light-receiving part 221, respectively. In a normal cordless telephone device, since the base unit 220 is a mobile phone set at a fixed position and the handset 210 moves, the handset 210 is arranged in the charger 212 at the fixed position, so that the infrared light emitting unit 211 is arranged. And the position of the light receiving unit 221 are fixed. Therefore, in this configuration, when the base unit 220 detects the disconnection of the infrared light and generates an alarm, the reception console 131 or the mobile phone of the security company registered in advance via the telephone network 230 by transmitting a predetermined dial is used. The terminal 132 is called to notify an alarm. Further, since base unit 220 communicates via a wireless line, it can be freely moved to a desired position and fixedly installed. Similarly, the charger 212 of the handset 210 can be moved, and the setting location of the infrared light path for security can be freely selected.

  However, in an inexpensive system configured with a conventional cordless telephone device, the infrared light transmitting unit and the receiving unit are almost fixed at opposite positions, so that only one place can be selected as a thief intrusion path, for example. Therefore, when there are a plurality of monitoring sections as such approach roads in a wide area and this cordless telephone device is installed, a plurality of sets are required as a security system, so the equipment cost is reduced. It is disadvantageous for reduction.

  Hereinafter, embodiments will be described with reference to the drawings. The drawings mainly show portions related to the present invention, but some of them are omitted in the drawings even if they are essential in function.

  A first embodiment of the present invention will be described with reference to FIG.

  FIG. 1 is an explanatory diagram showing an embodiment of a security system configuration according to the present invention.

  As shown in the figure, this crime prevention system includes infrared transmission / reception devices 1-A, 1-B, 1-C and a wireless communication device 2, and these are connected to each other by infrared rays. Therefore, the positions of the opposing light emitting part and light receiving part are fixed.

  The infrared transmission / reception device 1-A is the infrared transmission device having the function of only infrared transmission including the infrared light emitting unit 11S. The infrared transmission / reception device 1-B includes an infrared light receiving unit 11R and an infrared light emitting unit 11S. While the infrared light receiving unit 11R receives infrared rays from the infrared transmission / reception device 1-A, the infrared light transmission unit 11S transmits the infrared transmission / reception device 1-B. It is said 2nd infrared transmitter-receiver which light-emits infrared rays to C. Therefore, the infrared transmission / reception device 1-B can be cascade-connected between the infrared transmission / reception devices 1-A and 1-C, and can be substituted for the infrared transmission device using only the transmission function.

  The infrared transmission / reception device 1-C includes a plurality of infrared light receiving units 11R and one infrared light emitting unit 11S, and receives infrared rays from the infrared light emitting unit 11S to the wireless communication device 2 while receiving light by all the infrared light receiving units 11R. It is said 1st infrared transmitter / receiver which light-emits. Therefore, the infrared transmission / reception device 1-C can notify the wireless communication device 2 of the disconnection information when the infrared light receiving unit 11R receives an infrared reception interruption by the infrared light emission interruption.

  The wireless communication device 2 includes an infrared light receiving unit 21, an infrared abnormality detection unit 22, an output unit 23, an automatic transmission unit 24, an antenna 25, and a power supply unit 26. The infrared ray abnormality detection unit 22 that monitors infrared rays received from the infrared transmission / reception device 1-C in the infrared light reception unit 21 determines that an abnormality has occurred when detecting a light reception interruption for a predetermined time or more, and an abnormality has occurred in the output unit 23. For example, flash light emission, lamp lighting, display panel image display, etc., and alarm messages by visual audibility such as alarm sounds, voice guidance, etc. are generated. On the other hand, when the automatic transmission unit 24 receives a notification of the occurrence of an abnormality from the infrared abnormality detection unit 22, the automatic transmission unit 24 automatically transmits, for example, a destination of a related department registered in advance via the communication network and sends an alarm message through the antenna 25. Deliver.

  Since such a configuration is adopted, infrared ray abnormality detection of the wireless communication device 2 is detected regardless of whether the infrared ray that connects the infrared transmission / reception devices 1-A, 1-B, 1-C and the wireless communication device 2 is interrupted. An abnormality equivalent to the occurrence abnormality can be detected by the unit 22. Therefore, it is possible to transmit an infrared reception failure alarm message to the related department. In addition, since the infrared transmission / reception devices 1-A, 1-B, 1-C and the wireless communication device 2 can be provided with infrared monitoring points at a plurality of locations, it is possible to set a warning area with infrared rays over a wide range.

  The infrared transceivers 1-A, 1-B, 1-C simply emit infrared rays, and the infrared transceivers 1-B, 1-C only need to emit infrared rays while receiving infrared rays. Therefore, an inexpensive system configuration is possible. When the wireless communication device 2 detects the disconnection of infrared rays, the wireless communication device 2 may automatically send a predetermined alarm message to a predetermined destination. Therefore, the wireless communication device 2 can be used only by adding an infrared light reception function, an abnormality detection function thereof, and an automatic alarm message transmission to a destination registered in advance to an inexpensive mobile phone.

  In the first embodiment described above, an alarm message is sent to the relevant department as a crime prevention abnormality when the infrared ray is cut off beyond a predetermined time limit, but it is known where the infrared ray break has occurred in a number of areas. I can't.

  Here, the wireless communication device is equipped with a function of transmitting code data as a combination of a plurality of frequencies corresponding to the operation buttons as infrared data by using inexpensive equipment similar to that used for remote controllers such as home appliances. It shall be. For example, as infrared data, an infrared deployment location code, a light emitting device number code, an abnormal content code, and the like are set in advance in the transmission format.

  A second embodiment of the present invention will be described with reference to FIG.

  FIG. 2 shows an embodiment corresponding to the configuration of the infrared transmitting / receiving apparatus 1-C in FIG. Although the infrared transmitter / receiver 1-A, 1-B in FIG. 1 can operate in the configuration of FIG. 2, it is only necessary to remove an extra component from this configuration. Here, a configuration in which the infrared transmission / reception device 1-C also exhibits the functions of the infrared transmission / reception devices 1-A and 1-B will be described.

  Accordingly, the illustrated infrared transmission / reception apparatus includes a forced transmission mode corresponding to the function of the infrared transmission / reception apparatus 1-A, a reception data waiting mode corresponding to the function of the infrared transmission / reception apparatus 1-B, and the infrared transmission / reception apparatus 1-C. Each of the communication device corresponding modes corresponding to the above functions can be set independently.

  The illustrated infrared transmission / reception apparatus includes an infrared light emitting unit 11S, an infrared transmission / reception mode setting unit 12, a transmission self-data storage unit 13S, an infrared data transmission unit 14, and a light emitting display unit 15 that function as the infrared transmission / reception device 1-A. Have

  The infrared transmission / reception mode setting unit 12 presets the above-described forced transmission mode, reception data waiting mode, and communication device compatible mode. In the present embodiment, these three modes are targeted. For example, if there is no special setting, the forced transmission mode can be set.

  In the transmission self data storage unit 13S, for example, a device number code assigned to the infrared transmitting / receiving device itself as infrared data emitted by infrared rays is registered in advance. Further, for example, this data may be a number code given to the emitted infrared rays. When receiving the instruction of the forced transmission mode from the infrared transmission / reception mode setting unit 12, the infrared data transmission unit 14 reads the self data from the transmission self data storage unit 13S, and transmits the infrared data having the self data from the infrared light emitting unit 11S. To do. The infrared data transmission unit 14 confirms the transmission of infrared data and notifies the light emission display unit 15, for example, turns on an LED (light emitting diode) to notify that the infrared light is being emitted.

  As functions of the infrared transmission / reception device 1-B, the infrared transmission / reception device 1-A is equipped with an infrared light receiving unit 11R, a reception data storage unit 13R, an infrared data reception analysis unit 16, a reception data collation unit 17, and a timer 18. Is added. In the reception correspondence data storage unit 13R, for example, a device number code assigned to an infrared transmission / reception device as an infrared transmission source is registered in advance as infrared data received by infrared rays. Further, for example, the infrared data may be a number code given to the received infrared light.

  The infrared data reception analysis unit 16 analyzes the infrared data received by the infrared light receiving unit 11R and sends it to the reception data collation unit 17, and notifies the timer 18 of the detection of infrared reception and starts the timer 18 timed measurement. . The reception data collation unit 17 compares the data scheduled to be transmitted by infrared from the transmission source registered in advance in the reception correspondence data storage unit 13R with the data transmitted from the infrared data reception analysis unit 16, and the infrared data transmission unit described above. 14 notifies the data match together with the received data.

  The infrared data transmission unit 14 receives the received data together with the “match” notification from the reception data collating unit 17 in the reception data waiting mode or communication device compatible mode other than the forced transmission mode described above, and performs the above-described infrared transmission functional operation. And the timer 18 is initialized. In the mode for receiving the reception data in this way, the infrared data transmission unit 14 transmits the reception data instead of the self data of the transmission self data storage unit 13S in normal reception. On the other hand, in the case of abnormality, the self data and predetermined alarm data in the transmission self data storage unit 13S are transmitted. As a result, it is possible to identify a failure location due to infrared light reception interruption or reception data abnormality.

  The timer 18 presets a time during which infrared rays cannot be normally received as a time limit for detecting an abnormality, notifies the infrared data transmission unit 14 that this time limit has been reached, and stops emitting infrared light.

  As functions of the infrared transmitting / receiving apparatus 1-C, a plurality of infrared light receiving units 11R and an infrared scanning unit 19 that sequentially scans the plurality of infrared light receiving units 11R to send infrared data to the infrared data reception analysis unit 16 Is added. The infrared reception correspondence data storage unit 13R stores a plurality of infrared transmission source correspondence data. The infrared scanning unit 19 scans the infrared data received by the infrared light receiving unit 11 </ b> R at a predetermined cycle and sends it to the infrared data reception analysis unit 16. The infrared data reception analysis unit 16 analyzes the received infrared data and sequentially sends it to the reception data collation unit 17. Subsequent functions are the same as described above.

  In addition, each of the infrared transmission / reception devices 1-A, 1-B, and 1-C ensures that the infrared transmission / reception devices 1-A, 1-B, and 1-C have a normal operation by a timer on the infrared reception side. In this order, the equipment is sequentially set while confirming that infrared rays are normally transmitted by turning on the LED of the light emitting display unit 15.

  Next, main operation procedures of the infrared transmitting / receiving apparatus 1-C will be described with reference to FIGS. This procedure includes the operation procedure of each of the infrared transmitting / receiving apparatuses 1-A and 1-B for selecting the mode setting.

  First, in the case where the infrared transmission / reception apparatus 1-A is equivalent in which the forced transmission mode is set in the infrared transmission / reception mode setting unit 12 (YES in step S1), the infrared data transmission unit 14 receives a notification of the mode setting. The infrared data transmission unit 14 transmits infrared light including self data read from the transmission self data storage unit 13S from the infrared light emitting unit 11S by light emission (step S2), and instructs the light emitting display unit 15 to turn on the LED (procedure). S3) to display “infrared transmission”.

  Next, a case equivalent to the infrared transmission / reception apparatus 1-B in which the reception data waiting mode is set in the infrared transmission / reception mode setting unit 12 will be described.

  That is, when the procedure S1 is “NO”, the infrared data reception analyzing unit 16 drives the timer 18 to start measurement (procedure S5) when receiving infrared data from the infrared light receiving unit 11R (procedure S4). On the other hand, the infrared data reception analysis unit 16 analyzes the data by setting the reception data waiting mode (YES in step S6), and sends the analysis data to the reception data collation unit 17 when the data reception is completed (YES in step S7). . The reception data collation unit 17 reads the correspondence data from the reception correspondence data storage unit 13R and compares it with the received data, and determines the match (step S8).

  If this step S8 is “NO” and there is no data match and the time limit of the timer 18 has not been reached (NO in step S9), the procedure returns to S6 and is repeated.

  If the data in the step S <b> 8 is “YES” and the data match, the received data collation unit 17 sends the received data together with the “match” information to the infrared data transmission unit 14. The infrared data transmitter 14 receives the “match” information and initializes the timer 18 (step S10). In the case of the initial drive of the apparatus, the LED of the light emission display unit 15 is not lit (NO in step S11), so that the infrared data transmission unit 14 receives the reception received from the reception data verification unit 17 unlike the forced transmission mode. Infrared light including data is transmitted from the infrared light emitting unit 11S by light emission (procedure S12) and the light emitting display unit 15 is instructed to turn on the LED (procedure S13) to display “infrared transmitting”.

  If the procedure S11 is “YES” and the LED is lit, or if the LED is lit in the procedure S13, the procedure returns to the procedure S5 and is repeated from the start of the timer 18 measurement.

  In addition, when the procedure S9 is “YES” and the time limit of the timer 18 is reached, the infrared data transmission unit 14 that has received this notification includes predetermined alarm data and self data read from the transmission self data storage unit 13S. Infrared light is emitted from the infrared light emitting unit 11S (step S14) and the timer 18 is initialized (step S15).

  Furthermore, the case of the infrared transmission / reception device 1-C in which the communication device compatible mode is set in the infrared transmission / reception mode setting unit 12 will be described.

  This is a case where the above step S6 is “NO”. Since there are a plurality of corresponding data in this mode, the reception data collation unit 17 compares the data received sequentially from the infrared data reception analysis unit 16 with the data stored in the reception correspondence data storage unit 13R (step S21). The reception data collation unit 17 notifies the infrared data transmission unit 14 with the “match” information that the normal reception (YES in step S21) and the matching of all corresponding data (YES in step S22) have been confirmed. To do. Accordingly, the infrared data transmission unit 14 proceeds to the above step S10 and initializes the timer 18.

  If step S7, step S8, step S21, or step S22 is “NO” and there is no normal reception of data, the procedure first proceeds to step S9 and returns to step S6 until the timer 18 reaches the time limit and is repeated. .

  The function described in the second embodiment is that the security system according to the present invention is set by normal transmission / reception of data when each of the infrared transmission / reception devices 1-A, 1-B, 1-C handles infrared data in FIG. Up to. That is, the second embodiment emits light only after receiving infrared rays normally, and detects an abnormal reception of data including infrared ray reception interruption as an alarm. However, as described in the first embodiment, the infrared ray reception interruption is performed. It is good also as notifying to a radio | wireless communication apparatus using together the function to turn off light as it is. For example, when the received infrared ray is abnormal, the abnormality can be detected on the receiving side by the intermittent emission of the infrared ray that becomes abnormal, and the failure location can be notified by infrared data received thereafter. In this case, it is not necessary to use alarm data.

  A third embodiment of the present invention will be described with reference to FIGS. The drawings show only main parts related to the present invention, and some components necessary for functions are omitted.

In connection with the present invention, an automatic dial call is received from the device control unit 35, and a pre-registered party is called through the wireless network. The power supply unit 38 supplies power to the inside of the mobile phone 3, but can be charged by connecting a commercial power source from the charging connection detection unit 39 via the charger 4. The charging connection detection unit 39 detects charging by the charger 4 and notifies the device control unit 35 of the charging.

  In the security mode 41, for example, the start and setting of the security mode are recorded by the device control unit 35, and the respective states are visually displayed in different states predetermined by the liquid crystal display or the light emitting diodes on the output unit 34, for example. The In the automatic dialing destination number 42, a plurality of destination telephone numbers for notifying an alarm message are ordered and registered in advance. When the mobile phone is connected to the Internet or the like and e-mail is possible, the destination number can be a mail address. In the reception correspondence data 43, there is a possibility of reception, for example, the data of each of the infrared transceivers 1-A, 1-B, 1-C described above, or a number code given to the emitted infrared light is registered in advance. In addition, failure status data received from the infrared transceivers 1-B and 1-C that have detected the failure can be stored. In the transmission self-data 44, crime prevention system data to be sent to the alarm destination is registered in advance.

  In the coincidence counter value 45, the number of infrared data to be received is registered in advance. In the mismatch counter value 46, a count value that is determined to be an injury due to a mismatch of infrared reception data is registered in advance. In the alarm voice data 47, voice data of an alarm message sent to the telephone that is the alarm notification destination is registered in advance. For example, when various kinds of data such as an infrared fault position and fault status are included in the infrared data, an alarm message can be set in detail and selected.

  The infrared abnormality detection unit 51 detects an abnormality of infrared rays received by the light receiving unit 31. The reception data collation unit 52 collates the infrared data received by the light receiving unit 31 with the reception correspondence data 43 in the storage unit 33 and determines whether or not they match. The automatic dial transmission unit 53 is connected to the wireless line via the wireless control unit 36 and the antenna 37 when the abnormality of the infrared ray or infrared data received by the device control unit 35 is detected, and is registered in the automatic dial destination number 42 in advance. Call the destination phone by automatically dialing the phone number.

  The timer 54 operates to monitor the state at the time from the start of setting the security system. One counter 55 counts reception data normal reception at the start of security system setting, and the other counter 55 counts received data verification mismatch during security system setting.

  Next, the main operation procedure of the mobile phone 3 will be described with reference to FIGS. 5 to 6 and FIGS.

  The communication function operation (procedure S30) of the mobile phone 3 can be exhibited when not connected to the charger 4.

  In the case of security mode key input from the key input unit 32 (YES in step S31), the device control unit 35 starts setting the security mode setting in the security mode 41 of the storage unit 33 if the mode is set (YES in step S32). Store (step S33) and return to the first step S31. If the step S32 is “NO” and the mode setting is canceled, the security mode setting is initialized (step S34), and the process returns to the first step S31.

  When the above step S31 is “NO” and there is no key input or reception from the antenna 37 in the mobile phone 3, the device control unit 35 detects that it is connected to the charger 4 (YES in step S35). Next, when the device control unit 35 confirms the setting start state stored in step S33 from the crime prevention mode 41 (YES in step S36), the device control unit 35 starts charging and starts infrared reception by light reception of the light receiving unit 31. (Procedure S39). In addition, the device control unit 35 further blinks, for example, an LED (light emitting diode) of the output unit 34 to display “start setting of crime prevention mode” (step S40) and measure the abnormality detection time limit of the timer 54. Start (step S41).

  In this state, when the mobile phone 3 is disconnected from the charger 4, the device control unit 35 receives the charger release detection (YES in step S42) from the charging connection detection unit 39, so the timer 54 is initialized (step S43). ) To return to the procedure S30.

  When the procedure S42 is “NO” and the connection of the charger 4 is continued, the apparatus control unit 35 receives the infrared data from the light receiving unit 31 (step S44), so that the reception data collation unit 52 completes the reception of the data. After waiting (YES in step S45), the correspondence data of the reception correspondence data 43 and the reception data are collated (step S46).

  If this step S46 is “YES” and the received data match, the device control unit 35 increments the counter value of the counter 55 by one as a match counter (step S47) and performs polling for the next infrared data. To do. If the next infrared data is present (YES in step S48), the apparatus control unit 35 returns to step S44 and repeats the operation. When the received data matches all of the reception correspondence data 43, the counter value of the counter 55 matches the match counter value 45 (YES in step S49), so the apparatus control unit 35 sets “start setting” in the security mode 41. The record is updated during “setting”, and the LED of the output unit 34 is switched to continuous lighting and displayed (step S50). At the same time, the timer 54 and the counter 55 are initialized (step S51).

  When the procedure S46 or the procedure S49 is “NO” and the collation does not match and the timer 54 has not reached the time limit (the procedure S52 is NO), the apparatus control unit 35 returns to the procedure S42 and repeats the operation. Similarly, when the procedure S45 is “NO”, the procedure returns to the procedure S42 and is repeated.

  When the above step S52 is “YES” and the timer 54 reaches the time limit without matching, the counter value is initialized (step S53), and the output unit 34 of the mobile phone 3 is initialized. Then, for example, an alarm is displayed (step S54) by blinking of the LED and visual audibility of an alarm sound from the speaker or a buzzer. Therefore, the security system setting person can check the arrangement of each device and correct the arrangement to the normal setting that reaches the procedure S51.

  When the security mode is being set in step S51, the device control unit 35 starts measuring the timer 54 time (step S61), while continuing to receive infrared data by polling. Therefore, the apparatus control unit 35 repeats the procedure in which the procedure S62 is “NO” and the timer time limit is not reached (NO in procedure S63) until the reception of infrared data is completed (YES in procedure S62).

  Upon completion of the infrared data reception in which the procedure S62 is “YES”, the apparatus control unit 35 uses the received data collating unit 52 to determine whether the corresponding data in the received correspondence data 43 matches the received data (YES in step S64). Next infrared data is received (step S65). In this state, the apparatus control unit 35 continues the crime prevention state by repeating the procedure from the procedure 62 until the charger release detection from the charging connection detection unit 39 (YES in step S66).

  When the above step S64 is “NO” and the received data does not match, the apparatus control unit 35 increments the counter value of the counter 55 by one as the mismatch counter value (step S68). The apparatus control unit 35 collates this counter value with the mismatch counter value 46 of the storage unit 33, and repeats the subsequent steps following the above step S65 in which the next infrared data is received until the collation match (YES in step S69).

  When this procedure S69 is “YES” and the counter value by the counter 55 becomes abnormal due to the mismatch counter value 46, the counter value of the counter 55 is initialized (procedure S70), and the output unit 34 of the mobile phone 3 uses, for example, LED An alarm is displayed by blinking of and an audible alarm from the speaker or a buzzer (step S71).

  The apparatus control unit 35 that has detected the alarm starts automatic dial transmission by the automatic dial transmission unit 53 (step S72). That is, the automatic dial transmission unit 53 selects the first telephone number registered in advance in the automatic dial destination number 42 (step S73), places a call via the radio control unit 36, and performs automatic dialing (step S74). Execute. If there is a response from the called party to the call (YES in step S75), the automatic dial transmission unit 53 extracts voice data having a predetermined warning message from the alarm voice data 47 in the storage unit 33 and sends it to the called party telephone. Transmit (step S76).

  As the security system, a predetermined process given by a party who has received an alarm, for example, the mobile phone 3 for which the security system is set is removed from the charger 4 by the party, so that the security mode setting is initialized. A predetermined procedure (procedure S77) is executed.

  When the above step S75 is “NO”, there is no response to the called party, and there is no detection during the called party (step S81 is NO), the device control unit 35 starts timed measurement of the timer 54 waiting for a response. (Procedure S82) and return to the procedure S75 until the timer time limit is reached (YES in procedure S83), and the subsequent procedures are repeated.

  When step S83 is “YES” and the timer time limit is reached, the apparatus control unit 35 initializes the timer 54 (step S84) and selects the next telephone number from the automatic dialing destination number 42 (step S85). If the telephone number to be the next notification destination is the automatic dialing destination number 42 (YES in step S86), the apparatus control unit 35 returns the procedure to step S73 and the called party answers from the first telephone number. The procedure is repeated until “YES” in the step S75.

  When the procedure S81 is “YES” and it is detected that the called party is busy, the apparatus control unit 35 proceeds to the procedure S85 and selects the next telephone number.

  Since such a configuration is adopted, the person concerned can know the alarm situation in detail, regardless of the simple and inexpensive crime prevention system.

  Furthermore, as described above, the wireless communication apparatus can be constructed not only by a mobile phone but also by a wireless information terminal such as a PDA capable of e-mail, a portable personal computer, or the like.

  Since it can be easily constructed by using a plurality of simple infrared transmission / reception devices and a portable wireless device including an infrared light receiving unit, it can be applied to uses where infrared monitoring is necessary, inexpensive and simple conditions are indispensable.
