Description

  The present invention relates to a crime prevention device that monitors illegal activities on a structure or a moving body.

  In a vehicle security device, an abnormality is detected by a sensor, a control unit receives a detection signal from the sensor, determines whether there is an illegal act (for example, a mischievous act or a theft act), and generates an alarm sound from an alarm device. There is something to generate.

  For example, when the gradient until the sensor output waveform reaches the peak value is larger than a predetermined value, it is determined to be illegal. In other words, a method has been devised in which an alarm is issued only when the rise of vibration or sound is abrupt (see Patent Document 1).

  Further, it is composed of at least two crime prevention devices installed in different places, each crime prevention device detects an abnormal state level, and at least one crime prevention device detects the abnormal state level detection result of the abnormality detection unit and other A crime prevention system has been devised that determines whether or not it is an artificial abnormal state (that is, an illegal act) from the abnormal state level data received by the crime prevention device. Patent Document 2).

Japanese Patent No. 3290160 Japanese Patent No. 5515146

  Since Patent Document 1 issues an alarm only when vibration or sound rises abruptly, it can be expected to suppress a false alarm when a large vehicle is detected or vibration due to an earthquake is detected. However, no effect can be expected for the suppression of false alarms when detecting vibrations caused by fireworks or thunder.

  Patent document 2 is a structure which includes a detection body in a structure or a moving body. Therefore, when the user is not near the structure or the moving body, the alarm may not be noticed.

  Against the background of the above problems, an object of the present invention is to provide a crime prevention device that can notify a user of an alarm more reliably.

A security device to solve the above problems
Including a master unit and a slave unit attached to a moving body or structure,
The master unit receives vibration detection information reflecting the vibration state of the moving body or structure from the slave unit, and the vibration state is abnormal based on the vibration detection information received by the master unit reception unit. Including a master unit determination unit that determines whether or not to suppress the execution of an alarm for notifying that the alarm is performed, and a suppression of alarm execution when the master unit determination unit determines to suppress the execution of the alarm A master unit that transmits alarm suppression information to the slave unit, and
The slave unit includes a vibration detection unit that detects vibration of the moving body or the structure, a slave unit determination unit that determines whether vibration detection information should be transmitted based on the vibration detected by the vibration detection unit, and a slave unit determination When the unit determines that the vibration detection information should be transmitted, a slave unit transmission unit that transmits vibration detection information reflecting the state of vibration to the master unit, a slave unit reception unit that receives alarm suppression information from the master unit, After the slave unit transmission unit transmits vibration detection information, when the slave unit reception unit receives alarm suppression information before a predetermined standby time elapses, no warning is performed and the standby time elapses. And an alarm execution unit for executing an alarm when alarm suppression information has not been received before.

  With the above configuration, the master unit that determines whether or not to suppress the alarm, detects the vibration and transmits it to the master unit, and when it does not receive alarm suppression information from the master unit, it plays a role Can be shared. Therefore, the parent device can be attached to an object different from the moving body or the structure. Moreover, even in a situation where communication between the parent device and the child device is not possible, an alarm can be performed on the child device. Thereby, since an alarm can be implemented at least when an alarm is required, it can serve as a security device.

The figure which shows the structure of a security device. The figure which shows the structure of a main | base station. The figure which shows the structure of a subunit | mobile_unit. The flowchart explaining the alarm control processing of a main | base station. The flowchart explaining the vibration alarm process of a subunit | mobile_unit. The flowchart explaining the vibration principal component detection process of a subunit | mobile_unit. The flowchart explaining the vibration condition detection process of a subunit | mobile_unit.

  As shown in FIG. 1, the security device 100 includes a parent device 10 and a child device 20 (generic name of 20a to 20d, the same applies hereinafter). The parent device 10 may be carried by the user (portable type) or may be installed in a predetermined place such as the user's room (stationary type).

  The configuration of the above-described portable parent device is “the parent device is carried by the user”. The user cannot grasp the state of vibration unless the user is in the vicinity of the first detection body installed in the vehicle as in Patent Document 2. Further, even when the first detection body is installed in the user's residence, an alarm may not be heard at every location in the residence. With this configuration, when the user carries the parent device, the vibration status can be grasped regardless of the vehicle or the residence as long as the user is within a communicable range with the child device.

  The subunit | mobile_unit 20 is the support | pillar 41 of the window glass of a vehicle 30 (mobile body of this invention), or a pillar (it may be vehicle interior side or vehicle interior outside) (20a), and a carport 40 (structure of this invention), for example. (20b), installed in the window glass 51 (20c), 52 (20d) (a window frame or a wall surface) of the residence 50 (the structure of the present invention).

  The configuration in which the slave unit 20a is attached to the vehicle 30 is “at least one of the slave units is attached to the vehicle”. With this configuration, it is possible to mainly monitor or prevent illegal activities on the vehicle.

  In addition, when attaching a subunit | mobile_unit to the vehicle 30, it is desirable to attach two or more like the B pillar of a driver's seat side and a passenger seat side, for example. It is relatively rare that illegal acts on the vehicle 30 are performed simultaneously from the driver's seat side and the passenger seat side (because those performing illegal acts tend to be nervous to make a noise). Therefore, when vibrations are detected almost simultaneously on both sides of the vehicle, it is considered that the possibility of an illegal action is low, and the accuracy of determination of alarm suppression described later can be improved.

  As shown in FIG. 2, the base unit 10 includes a control unit 11 (base unit determination unit of the present invention) including a known microcomputer and peripheral circuits, and a wireless communication unit 12 (base unit of the present invention) connected to the control unit 11. Device receiver, master transmitter), for example, a storage unit 13 using a flash memory, a display unit 14 using, for example, an LCD, a switch 15 (operation unit of the present invention), a speaker 16, an LED 17, and a vibrator 18. The base unit 10 operates with a battery (which may be a primary battery or a secondary battery: not shown) in the case of a portable type, and operates with a battery or a commercial power source (not shown) in the case of a stationary type.

  The control unit 11 implements various functions of the parent device 10 by executing the parent device control program stored in the storage unit 13.

  The wireless communication unit 12 communicates with the child device 20. As the communication standard, for example, Bluetooth (registered trademark), Wi-Fi (registered trademark), Zigbee (registered trademark), or the like is used.

  The display unit 14 notifies the operation state of the parent device 10 or the child device 20 based on an instruction from the control unit 11 (details will be described later).

  The switch 15 includes one or a plurality of switches, and is used by the user to perform various settings of the parent device 10 or predetermined functions.

  The base unit 10 may also serve as a vehicle key. For example, collation is performed by wireless communication between a smart key held by the user and an in-vehicle device mounted on the vehicle, and the door is unlocked / locked based on the collation result without using a mechanical key. It can also be used as a smart key in a smart key system that performs an operation desired by the user, such as engine start.

  The above-described configuration is “the master unit also serves as a vehicle key”. With this configuration, when the security device is mainly used to monitor or prevent illegal activities on the vehicle, the user can grasp the vibration status detected by the slave unit by simply placing the vehicle key close to the user. . Also, when one vehicle is used by multiple users (shared with family, rental car, company car), if the slave unit is attached to the vehicle and the master unit also serves as the vehicle key, Since the user who uses (drives) owns the parent device, an illegal action against the vehicle can be detected and an alarm can be implemented even at the place of departure (a point where the vehicle is not a permanent place). Furthermore, since the user never forgets the parent device (vehicle key), the user can grasp the vibration status of the vehicle.

  In the smart key system, when the parent device 10 also serves as a smart key, the wireless communication unit 12 includes a circuit that enables wireless communication (for example, high frequency communication, long wave communication) with the in-vehicle device.

  Further, the switch 15 may include a switch (for example, door locking / unlocking) for using a so-called remote keyless entry function when the base unit 10 also serves as a smart key. When the user operates the switch, the wireless communication unit 12 transmits a command signal requesting to perform an operation according to the operation mode.

  The speaker 16, LED 17, and vibrator 18 (all of which are notification units of the present invention), based on instructions from the control unit 11, change the operating state of the parent device 10 or the child device 20 by voice message output, lighting / extinguishing, vibration, respectively. Notification is made (details will be described later). What is necessary is just to provide at least 1 among the display parts 14, the speaker 16, LED17, and the vibrator 18 as an alerting | reporting part.

  The above-described configuration is “the base unit includes a notification unit that performs notification based on the vibration detection information received by the base unit reception unit”. With this configuration, the parent device can grasp the vibration detection state of the child device. In addition, when the user recognizes that a loud sound (vibration is also generated) and there is no alarm or notification, there is anxiety that the handset (that is, the vibration detection unit) is operating normally. Can be resolved.

  As shown in FIG. 3, the slave unit 20 is similar to the master unit 10 connected to the control unit 21 (the slave unit determination unit and the alarm execution unit of the present invention) including a known microcomputer and peripheral circuits. A wireless communication unit 22 (slave unit transmission unit, slave unit reception unit of the present invention) having a configuration of, for example, a storage unit 23 using a flash memory, a vibration detection unit 24, a switch 25, a speaker 26, and an LED 27. The subunit | mobile_unit 20 operate | moves with a battery (not shown).

  The control part 21 implement | achieves the various functions of the subunit | mobile_unit 20 by running the subunit | mobile_unit control program memorize | stored in the memory | storage part 23. FIG.

  The memory | storage part 23 memorize | stores the identification information for identifying the subunit | mobile_unit 20 other than a subunit | mobile_unit control program. Thereby, the main | base station 10 can identify from which child apparatus the received information was transmitted.

  The vibration detection unit 24 uses, for example, a well-known triaxial acceleration sensor (which may be any of a piezoresistive type, a capacitance type, and a heat detection type). This sensor is also used in vehicle airbag systems and navigation systems. The vibration detection unit 24 converts the vibration state into an electric signal and outputs it to the control unit 21. The control unit 21 performs A / D conversion on the electrical signal and uses it in each process (described later).

  The switch 25 (only one switch is shown in FIG. 3 but a plurality of switches 25 may be provided) is used by the user for various settings of the slave unit 20 (for example, sensitivity adjustment of the vibration detection unit 24). Moreover, you may use for turning on / off a power supply.

  The speaker 26 and the LED 27 (both alarm execution units of the present invention) notify the detection state of the vibration detection unit 24 by outputting a voice message and turning on / off, respectively, based on an instruction from the control unit 21 (details will be described later). . What is necessary is just to provide at least 1 among the speaker 26 and LED27 as an alarm implementation part.

  FIG. 4 shows an alarm control process included in the parent device control program. The base unit 10 is in a waiting state for receiving vibration detection information from the handset 20 (20a to 20d). In this state, it is only necessary that at least the receiving circuit included in the wireless communication unit 12 is operating, and other circuits may be in a so-called sleep state (power saving operation state).

  When vibration detection information is received from any of the slave units 20 (S11: Yes), the sleep state returns to the normal operation state. Subsequently, timer 1 (for example, 1 second timer, first determination time of the present invention), timer 2 (for example, 2 second timer, second determination time of the present invention), and timer 3 (for example, 60 second timer) are sequentially started ( S12, S13, S14). After that, the apparatus enters a standby state for receiving vibration detection information from the slave unit (particularly, the slave unit that has not transmitted the vibration detection information in S11) (S15). Then, it waits until the timer 1 expires.

  When the timer 1 expires (S16: Yes), it is determined whether or not the vibration detection information has been received from all the slave units while the timer 1 is operating. When the vibration detection information has been received from all the slave units (S17: Yes), alarm suppression information including not performing an alarm or suppressing the execution of the alarm is transmitted to all the slave units ( S26).

  The above-mentioned configuration is “when the master unit receiving unit receives vibration detection information from all the slave units within a predetermined first determination time, the master unit determining unit determines to suppress the execution of the alarm”. It is. For example, since fireworks explosions and vibrations caused by thunder are wide-ranging, it is considered that vibrations are detected in all slave units. In addition, in an illegal act on a house or a vehicle (for example, destruction of a window glass), vibration is considered to occur locally and in a relatively short time. With this configuration, it is possible to determine whether or not to suppress an alarm when vibration generated in a wide range in a relatively short period of time is detected by a simple method.

  On the other hand, when the vibration detection information is not received from all the slave units while the timer 1 is operating (S17: No), all the slave units (particularly, the slave units that have not transmitted the vibration detection information in S11). (S18). And it waits until the timer 2 times out.

  When the timer 2 has timed up (S19: Yes), while the timer 2 is operating, when the vibration detection information is not received from a plurality of slave devices that are not all, that is, the child that first transmitted the vibration detection information. When vibration detection information has not been received from all the slaves except the machine (S20: No), the process proceeds to S21.

  On the other hand, when the vibration detection information is received from a plurality of child devices that are not all while the timer 2 is operating (S20: Yes), the vibration principal component information (details) is transmitted to the child device that has transmitted the vibration detection information. Request transmission (described later) (S23). Thereafter, vibration principal component information is received from the slave unit (S24). Then, it is determined whether or not these vibration main components (for example, the frequency or period of the fundamental wave of vibration) match or fall within a predetermined range.

  When the vibration main components match (S25: Yes), alarm suppression information is transmitted to the slave unit (S26). On the other hand, when the vibration principal components do not match (S25: No), the process proceeds to S21.

  The above configuration is “when the base unit receiving unit receives vibration detection information from a plurality of slave devices that are not all within a predetermined second determination time, the base unit transmitting unit has a predetermined vibration main component. When the main unit receiving unit receives vibration main component information from a plurality of slave units, the base unit determination unit determines that the values of these vibration main components are within a predetermined range. When it is determined that the implementation of the alarm is suppressed and the slave unit transmission unit transmits the vibration detection information, the slave unit transmission unit receives the vibration main component detection request. The frequency or period of the fundamental wave of the vibration detected by is used as a vibration principal component and transmitted by including it in the vibration principal component information.

  With this configuration, it is possible to suppress the alarm from being executed for a relatively long vibration duration such as a vibration or an earthquake when a large vehicle or an illegally modified vehicle passes. There may be a slave unit that does not determine that vibration detection information should be transmitted even if the vibration is the same, depending on the setting value of the vibration detection sensitivity at the location where the slave unit is installed and the individual vibration detection units. Thus, by setting “a plurality of slave units that are not all the slave units (vibration detection units)” as a determination condition, it is possible to more accurately determine whether to suppress the alarm.

  In S21, it is determined whether or not vibration detection invalid information (details will be described later) has been received from the slave unit that first transmitted the vibration detection information. When vibration detection invalid information is received (S21: Yes), the process proceeds to S27. On the other hand, when the vibration detection invalid information is not received (S21: No), an alarm is given to the user (S22). When the alarm is issued, it may be displayed on the display unit 14, or a voice message may be transmitted from the speaker 16, the LED 17 may be blinked, or the vibrator 18 may be vibrated according to the magnitude of vibration. On the other hand, since the slave unit that has transmitted the vibration detection information automatically outputs an alarm unless it receives the alarm suppression information, it does not need to do anything. At this time, when an alarm is to be issued to another slave unit, an alarm output request may be transmitted to the slave unit. Thereafter, the process proceeds to S27.

  The configuration described above is as follows: “After the base unit receiving unit receives the vibration detection information from one slave unit, no vibration detection information is received even if a predetermined second determination time has elapsed, and the slave unit is When the vibration detection invalid information for invalidating the vibration detection information is received, the base unit determination unit determines that the alarm is suppressed and the slave unit transmission unit transmits the vibration detection information, and then the vibration detection unit When the vibration similar to the vibration included in the vibration detection information is continuously detected for a predetermined invalidity determination time, the slave unit transmission unit transmits the vibration detection invalid information ”. With this configuration, when a vehicle equipped with a so-called “explosion muffler” is stopped, when a strong vibration is continuously detected only by a specific slave unit due to resonance, etc., the alarm is suppressed. Can do. In addition, since it is determined that the vibration detection is invalid on the slave unit side, the processing load on the master unit can be reduced.

In S27, at least one of the display unit 14, the speaker 16, the LED 17, and the vibrator 18 is used, and any one of the following notifications is performed.
-Notify that the vibration detection information has been received or the content of the vibration detection information.
-Informs that an alarm is to be executed in the slave unit.

  When notifying that the vibration detection information has been received in S27, alarm instruction information for performing an alarm may be transmitted to the slave unit that has transmitted the vibration detection information by operating the switch 15 of the user.

  Next, a transmission request (details will be described later) of vibration status information is transmitted to at least the slave unit that transmitted the vibration detection information (of course, all slave units may be used) (S28).

  The above-described configuration is as follows: “When a predetermined transmission condition is satisfied, the parent device transmission unit transmits a transmission request for vibration state information including the vibration state in the child device, and the parent device reception unit transmits the vibration state information. When received, the notification unit notifies the vibration status included in the vibration status information, and when the slave unit reception unit receives a request for transmission of the vibration status information, the slave unit is detected by the vibration detection unit. The peak value of the fundamental wave of vibration is set as the vibration status, and is included in the vibration status information and transmitted. With this configuration, the user can check the current vibration status in real time regardless of whether or not an alarm is issued. Furthermore, if the parent device includes an operation unit, it is possible for the user to instruct the execution of an alarm according to the notified vibration status.

  More specifically, “when the notification unit performs notification, it is assumed that the transmission condition is satisfied”. With this configuration, the user can check the current vibration status in real time along with the notification content (alarm or simple notification).

  A configuration may also be adopted in which “the base unit transmission unit transmits a transmission request for vibration status information for a predetermined period”. This corresponds to a configuration using the timer 3.

  Further, a vibration status information transmission request may be transmitted by the user's operation of the switch 15. This configuration is “the master unit has an operation unit for the user to perform operation input, and the transmission condition is satisfied when the user performs a predetermined operation input to the operation unit”. It is. With this configuration, for example, when there is a loud sound but there is no alarm or notification, the user can check the current vibration status in real time.

  Thereafter, vibration status information is received from each slave unit (S29). Next, additional notification based on the vibration status information is performed (S30). Then, the processes after S28 are repeated at a predetermined interval until the timer 3 times out.

  At the time of the additional notification, the vibration state may be displayed on the display unit 14 in real time, the voice message is sent from the speaker 16, the LED 17 blinks, or the vibrator 18 is vibrated according to the magnitude of the vibration. Also good.

  When the timer 3 times out (S31: Yes), the execution of the additional notification is terminated (S32), and then the present process is terminated. In S32, a command for stopping the execution of the alarm may be transmitted to the slave unit that has performed the alarm.

  FIG. 5 shows a vibration alarm process included in the handset control program. The subunit | mobile_unit 20 is a vibration detection waiting state of the vibration detection part 24. FIG. In this state, it is sufficient that at least the vibration detection unit 24 is operating, and other circuits may be in the sleep state.

  First, when the vibration detection unit 24 detects a vibration greater than a specified value, the normal operation state is restored. Next, for example, when the detected maximum value of the amplitude exceeds a predetermined threshold (S51: Yes), vibration detection information is transmitted to the parent device 10 (S52). Subsequently, a timer A (for example, a 3-second timer, the standby time of the present invention) is started (S53).

  Next, it is determined whether or not the vibration detected in S51 is continued. When vibration does not continue (S54: No), it is determined whether or not alarm suppression information is received from the parent device 10. When the alarm suppression information is received (S55: Yes), the process proceeds to S60. That is, the implementation of the alarm is suppressed. On the other hand, when alarm suppression information is not received (S55: No), it is determined whether or not a transmission request for vibration principal component information has been received from base unit 10.

  When the transmission request for the vibration principal component information is not received (S56: No), the process proceeds to S57. On the other hand, when a transmission request for vibration principal component information is received (S56: Yes), vibration principal component detection processing is executed (S63, see FIG. 6). Thereafter, the process proceeds to S57.

  In S57, it is determined whether or not a transmission request for vibration status information is received from the parent device 10. When the vibration status information transmission request is not received (S57: No), the process proceeds to S58. On the other hand, when a transmission request for vibration status information is received (S57: Yes), a vibration status detection process is executed (S64, see FIG. 7). Thereafter, the process proceeds to S58.

  In S58, it is determined whether or not the timer A has expired. When the timer A has not expired (S58: No), the process returns to S55. On the other hand, when the timer A expires (S58: Yes), an alarm is performed (S59). Thereafter, the process proceeds to S60.

  When the alarm is performed, at least one of the speaker 26 and the LED 27 is used. For example, a voice message is sent from the speaker 26 according to the magnitude of the vibration (a buzzer sound having a pattern according to the magnitude of the vibration may be sent), or the LED 27 is blinked.

  The alarm may be implemented for a predetermined time, such as one minute. Moreover, you may implement until the stop of an alarm is transmitted with respect to the subunit | mobile_unit which has implemented the alarm by operation of the switch 15 of the main | base station 10 by the user.

  On the other hand, when the vibration continues (S54: Yes), the timer B (for example, the 2-second timer, the invalidity determination time of the present invention) is started (S66). Next, the detection state of the vibration detector 24 is sampled (S67). As a result of sampling, when the vibration exceeding the predetermined value is not continued (S68: No), the process proceeds to S55. On the other hand, when the vibration exceeding the predetermined value continues (S68: Yes), it is determined whether or not any data has been received from the parent device 10.

  When data is received from the parent device 10 (S69: Yes), the process proceeds to S55. On the other hand, when data is not received from base unit 10 (S69: No), it is determined whether timer B has timed up. When the timer B has not expired (S70: No), the process returns to S67. On the other hand, when the timer B expires (S70: Yes), for example, it is determined whether or not the vibration detected in S51 continues for a certain period of time.

  When the constant vibration is not continued (S71: No), the process returns to S55. On the other hand, when the constant vibration continues (S71: Yes), vibration detection invalid information indicating that the vibration detected in S51 is not a target of alarm is transmitted (S72). Thereafter, the process proceeds to S60.

  In S60, a timer C (for example, a 1 second timer) is started. Next, it is determined whether or not a transmission request for vibration status information has been received from the parent device 10. When the vibration status information transmission request is not received (S61: No), the process proceeds to S62. On the other hand, when a transmission request for vibration status information is received (S61: Yes), a vibration status detection process is executed (S65, see FIG. 7), and then the process proceeds to S73. In S73, the timer C is restarted, and the process proceeds to S62.

  In S62, it is determined whether or not the timer C has expired. When the timer C has not expired (S62: No), the process returns to S61. On the other hand, when the timer C has expired (S62: Yes), this process is terminated.

  FIG. 6 shows a vibration principal component detection process corresponding to S63 in FIG. First, a timer D (for example, a 0.5 second timer) is started (S91). Next, the detection state of the vibration detector 24 is sampled (S92). Sampling is performed until the timer D expires.

  When the timer D expires (S93: Yes), the period or frequency of the vibration main component is extracted based on the sampling result (S94). In the extraction method, for example, a harmonic component is removed by a low-pass filter, and a time period in which the signal level (that is, voltage) increases is extracted. Further, among the frequency components obtained by the fast Fourier transform, the one having the highest signal level may be used as the fundamental wave.

  Finally, vibration principal component information including the frequency of the fundamental wave or its period is created and transmitted to the parent device 10 (S95).

  FIG. 7 shows a vibration state detection process corresponding to S64 and S65 of FIG. First, a timer E (for example, a 0.5 second timer) is started (S111). Next, the detection state of the vibration detection unit 24 is sampled (S112). Sampling is performed until timer E expires.

  When the timer E expires (S113: Yes), the vibration main component is extracted based on the sampling result (S114). The extraction method is the same as, for example, the vibration principal component detection process of FIG. Next, the level of the extracted vibration main component (for example, the peak value of the fundamental wave of vibration) is calculated (S115).

  Finally, vibration status information including the peak value is created and transmitted to the parent device 10 (S116).

  The above-described embodiment is an exemplification, and various modifications based on the knowledge of those skilled in the art are possible without being limited to the above-described embodiment without departing from the scope of the claims.
