Description

  The present invention relates to a security system used for intruder monitoring in buildings such as houses and office buildings.

  The detection status of security sensors attached to building windows has been collected on the alarm side via a wired signal line in the past. However, in recent years, the number of cases collected exclusively by wireless communication has increased (for example, Patent Document 1), specifically, a relay device that relays wireless communication between a security sensor and an alarm device collects detection states of a plurality of security sensors and transmits them to the alarm device as needed. .

Therefore, for example, the start of intruder monitoring when going out and the cancellation of intruder monitoring when returning from going out are performed to the repeater directly or via the alarm side, and relayed according to the setting state The device wirelessly transmits the collected detection status of the security sensor to the alarm device side or discards it without wireless transmission.
JP 2004-206531 A

  However, in the configuration as described above, the repeater always collects the detection state of the security sensor regardless of whether the intruder is being monitored. Therefore, particularly when the repeater is battery-driven, the power consumption As a result, the battery life will be shortened.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wireless communication type security system that monitors an intruder using a repeater and a security sensor in which intruder monitoring and cancellation thereof are set. Another object of the present invention is to provide a security system capable of suppressing the power consumed in the collecting operation of the detection state of the security sensor.

  In order to achieve the above object, the security system of the present invention described in claim 1 includes, as described in the basic configuration diagram of FIG. The intruder monitoring is performed by wirelessly connecting the repeater 3 set to monitor and release the intruder and the alarm device 1 that outputs the intruder alarm according to the content of the detection state that the security sensor 2 outputs wirelessly. In the security system that performs the above, the relay 3 is provided with the setting state output means A that wirelessly outputs the intruder monitoring and release setting state, and the security sensor 2 is provided with the setting state output means A. When the output is an intruder monitoring state, the intruder detection operation by the security sensor 2 is validated, and the output of the setting state output means A is intruder monitoring. The sleep unit B that disables the intruder detection operation by the security sensor 2 when in the released state, and the security that is provided in the alarm device 1 and the intruder detection operation is enabled by the sleep unit B A security alarm output means C that receives the wireless output of the detection state by the sensor 2 directly or via the relay 3 and outputs an intruder alarm according to the detection state of the security sensor 2; It is characterized by.

  According to the security system of the present invention as set forth in claim 1, while the setting state of the intruder monitoring and canceling output from the repeater 3 wirelessly by the setting state output means A is the intruder monitoring canceling state The intruder detection operation by the security sensor 2 is invalidated by the sleep means B, and the intruder detection operation by the security sensor 2 is validated by the sleep means B while the intruder is being monitored.

  Therefore, the security sensor 2 actually performs the intruder detection operation only while the intruder monitoring and release setting state is the intruder monitoring state. Since the security sensor 2 does not perform the intruder detection operation, the power consumed for the collection operation of the detection state of the security sensor 2 is suppressed, and even if the device involved in the collection is battery-driven, the battery Can extend the service life.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A security system according to an embodiment of the present invention shown in a block diagram in FIG. 2 includes a gas leak alarm 1 (corresponding to an alarm in the claims) and a window sensor 2 that detects opening and closing of the window (in claims). And a crime prevention repeater 3 (corresponding to a repeater in claims) in which intruder monitoring and cancellation thereof are set based on the detection state of the window sensor 2 are included. The gas leak alarm 1, the window sensor 2, and the crime prevention repeater 3 are installed at different locations in one building.

  Here, the crime prevention repeater 3 detects whether or not there is an intruder from a window or the like where the window sensor 2 is installed by operating a remote controller (not shown) (start of intruder monitoring) or cancels (intrusion). When the setting state changes, setting state data indicating the changed setting state is transmitted from the built-in wireless unit (not shown) to the window sensor 2. Is configured to do. Therefore, the crime prevention repeater 3 has the setting state output means A in the claims.

  The window sensor 2 detects the opening / closing of the window by detecting movement of the window frame, breakage of the window glass, or rotation of the crescent by using a magnet sensor, a reed switch, or the like, for example. A radio unit 22 for performing radio communication with the leak alarm device 1 and the crime prevention repeater 3 is added.

  As shown in the block diagram of FIG. 3, the radio unit 22 includes a communication high-frequency circuit unit RF, a modulation / demodulation processing digital processing circuit unit DP, and a control microcomputer unit (hereinafter abbreviated as “microcomputer unit”) μCOM. Integrated circuit LSI, a non-volatile memory NVM, an antenna AT connected to the communication high-frequency circuit unit RF, and a battery V as a power source, and an A / D converter CONV and a non-volatile circuit The volatile memory NVM is connected to the microcomputer unit μCOM.

  In the nonvolatile memory NVM, self-identification information used in wireless communication with the gas leak alarm device 1 and the crime prevention relay device 3 is registered in advance.

  Incidentally, a wireless unit (not shown) built in the crime prevention repeater 3 is configured in the same manner as the wireless unit 22 of the window sensor 2, but the reception function is omitted and is configured exclusively for transmission to the window sensor 2. Has been.

  Then, the microcomputer unit μCOM of the wireless unit 22 of the window sensor 2 performs the process shown in the flowchart of FIG. 4 according to a control program stored in an internal ROM (not shown).

  First, it is confirmed whether or not the setting state data from the crime prevention repeater 3 is received by the antenna AT or the communication high-frequency circuit unit RF and demodulated and inputted by the modulation / demodulation processing digital processing circuit unit DP (step S1). If not input (N in step S1), the process proceeds to step S9, which will be described later. If input (Y in step S1), the input setting state data indicates monitoring → release of intruder monitoring. (Step S3).

  If the input setting state data indicates intruder monitoring monitoring → cancellation (Y in step S3), the valid flag F secured in the RAM (not shown) is set to “1” (step S5). ), The process returns to step S1, and if it does not indicate monitoring → release of intruder monitoring (N in step S3), after setting the valid flag F to “0” (step S7), the process returns to step S1.

  Further, in step S1, when the setting state data from the security repeater 3 is not input in step S9, the process proceeds to (N). In step S9, it is confirmed whether the valid flag F is “0”. If yes (Y in step S9), the process returns to step S1.

  On the other hand, when the valid flag F is not “0” (N in step S9), the detection data indicating the open / closed detection state of the window to be monitored by the sensor main body 21 together with its own identification information registered in the nonvolatile memory NVM. Then, the signal is modulated by the modulation / demodulation processing digital processing circuit DP and wirelessly transmitted from the communication high-frequency circuit unit RF to the antenna AT to the gas leak alarm 1 (step S11), and then the process returns to step S1.

  As is clear from the above description, in the window sensor 2 of the present embodiment, steps S1 to S7 in the flowchart of FIG. 4 are processes corresponding to the sleep means B in the claims.

  As shown in FIG. 2, the gas leak alarm device 1 includes a conventionally known alarm device main body 11 that detects a gas by a sensor that detects a component of city gas or propane gas, generates and outputs an alarm signal, and a window sensor 2. And a wireless unit 12 for performing wireless communication.

  The alarm main body 11 has a built-in function for notifying by voice (alarm sound, alarm message) at the time of detection, and this voice notification function is not only for detecting a gas leak or fire, but also for wireless communication. The operation can be performed depending on the content of detection data input from the window sensor 2 via the unit 11.

  The wireless unit 11 is configured in the same manner as the wireless unit 21 of the window sensor 2 shown in FIG. 3, and the non-volatile memory NVM has its own identification information used in wireless communication with the gas leak alarm 1, etc. Registered in advance.

  The microcomputer unit μCOM performs the processing shown in the flowchart of FIG. 5 in accordance with a control program stored in an internal ROM (not shown).

  First, it is confirmed whether or not the alarm device main body 11 has detected a gas leak state (step S31). If detected (Y in step S31), the fact that the gas leak has been detected is notified by voice output (step S31). S33), the process returns to step S31.

  On the other hand, when the gas leakage state is not detected (N in step S31), the detection data from the window sensor 2 is received by the antenna AT or the communication high-frequency circuit unit RF and is received by the modulation / demodulation processing digital processing circuit unit DP. It is confirmed whether it has been demodulated and input (step S35). If it has not been input (N in step S35), the process returns to step S31.

  On the other hand, when the detection data from the window sensor 2 is input (Y in step S35), the content of the input detection data indicates that there is an intruder from the installation location of the window sensor 2. Whether there is an intruder from the installation location of the window sensor 2 (N in step S37) is checked, the process returns to step S31.

  On the other hand, when the content of the input detection data indicates that there is an intruder from the installation location of the window sensor 2 (Y in step S37), there is an intruder from the installation location of the window sensor 2. Is notified by voice output (step S39), and the process returns to step S31.

  As is clear from the above description, in the gas leak alarm 1 of the present embodiment, steps S35 to S39 in the flowchart of FIG. 5 are processes corresponding to the security alarm output means C in the claims. .

  Next, an operation (action) related to an alarm according to a detection result by the sensor main body 21 of the window sensor 2 in the security system of the present embodiment configured as described above will be described.

  First, the setting is changed from a state in which the presence or absence of an intruder is detected from a window or the like in which the window sensor 2 is installed (start of intruder monitoring) to a state of cancellation (intruder monitoring is canceled) by a remote controller (not shown). Then, setting state data indicating that is transmitted wirelessly from the security repeater 3 that has received this from the remote controller to the window sensor 2, and conversely, the window where the window sensor 2 is installed by the remote controller (not shown). When the setting is changed from the state of canceling intruder monitoring (cancellation of intruder monitoring) to the state of starting intruder monitoring (starting intruder monitoring) from the remote control 3 that has received this from the remote control Setting state data indicating that fact is transmitted to the sensor 2 wirelessly.

  Then, in the window sensor 2 that has received the setting state data wirelessly, the setting state by a remote controller (not shown) stops detecting the presence or absence of an intruder from a window or the like where the window sensor 2 is installed (intruder monitoring). While in the (released) state, the sensor body 21 does not detect the open / closed state of the window to be monitored.

  On the other hand, while the setting state by the remote controller (not shown) is a state in which the presence or absence of an intruder is detected from the window or the like where the window sensor 2 is installed (intruder monitoring is started), the monitoring by the sensor body 21 is performed. Content indicating that an open / closed state of the target window is detected, detection data indicating the detection result is wirelessly transmitted to the gas leak alarm 1, and that there is an intruder from the installation location of the window sensor 2 If it is, it will alert | report by an audio | voice output that there exists an intruder from the installation location of the window sensor 2 using the audio | voice alerting | reporting function which the alarm device main body 11 has in order to output the alarm of a gas leak .

  As described above, according to the security system of the present embodiment, the presence / absence of an intruder is detected (start of intruder monitoring) or is canceled from a window or the like on which the window sensor 2 is set, which is set by a remote controller (not shown). While it is set to stop the detection of the presence or absence of an intruder by notifying the window sensor 2 wirelessly from the security repeater 3 that has received it (cancellation of intruder monitoring) Is configured so as not to perform any wireless transmission / reception of the detection data of the window sensor 2, thereby suppressing the power consumed for the collection operation of the detection state of the window sensor 2 and extending the life of the driving battery. Can be achieved.

  In this embodiment, the case where the security sensor in the claims is the window sensor 2 has been described. However, for example, a door sensor that detects the unlocking / locking of the door by the rotation of the thumb turn and monitors the opening / closing of the door is used for crime prevention. Any sensor other than the window sensor may be used.

  Moreover, the alarm device connected to the wireless device to which the present invention is applied is not limited to the gas leak alarm device 1 shown in the above-described embodiment, and any alarm device having an audio alarm output function may be used. An alarm device or the like that outputs an alarm signal when an alarm state occurs may be an alarm device that does not have a function of detecting an alarm state and that has a simple alarm output function by voice. Of course.

  And the alarm status or failure status notification performed by the alarm device may be not only by voice but also by display or the like, and even such an alarm device can be an application target of the present invention. Needless to say.

  Furthermore, although this embodiment demonstrated the case where the radio | wireless units 12 and 22 were incorporated in the gas leak alarm 1, window sensor 2, and crime prevention repeater 3, this invention is an alarm device of the gas leak alarm 1. Even when the wireless units 12 and 22 are externally attached to the main body 11, the sensor main body 21 of the window sensor 2, and the crime prevention repeater 3, it is applicable.

  Even in that case, the gas leak alarm device 1 corresponding to the alarm device in the claims is configured to include the alarm device main body 11 and the wireless unit 12, and similarly, the alarm device in the claims. The window sensor 2 corresponding to is configured to have a sensor main body 21 and a wireless unit 22, and the crime prevention repeater 3 also constitutes an alarm device in the claims together with an external wireless unit Will do.

  Moreover, although this embodiment demonstrated the case where it comprised so that radio | wireless communication with the window sensor 2 and the gas leak alarm device 1 might be directly performed without going through the crime prevention repeater 3, the window sensor 2 and a gas leak alarm device were demonstrated. The wireless communication with the device 1 may be performed via the security repeater 3 as before, and in that case, the state set in the security repeater 3 is determined whether to perform intruder monitoring or to cancel. By notifying the window sensor 2 wirelessly and during the stop of the intruder monitoring, it is possible to obtain the same effect as the above-described embodiment by not performing wireless transmission / reception of detection data by the window sensor 2 at all.
