Description

  The present invention relates to a security device.

  2. Description of the Related Art Conventionally, there is known a security device in which a pyroelectric infrared sensor is installed on a ceiling or the like of a residence to form a monitoring area on a floor surface and monitor a person entering the monitoring area. The pyroelectric infrared sensor detects a change in the amount of received infrared light according to the object temperature.

  In recent years, automatic vacuum cleaners have been developed that perform cleaning while autonomously moving through each room or entrance of a residence. Such an automatic vacuum cleaner uses various sensors mounted to determine the shape, size, and dirt condition of the room to be cleaned. Then, the automatic vacuum cleaner calculates the optimum traveling pattern and operating time, and performs floor cleaning. In addition, the automatic cleaner detects the charging device using an optical sensor or the like when cleaning is completed or the remaining battery level becomes a predetermined amount or less. Then, the automatic cleaner automatically moves to the position of the detected charging device and performs charging.

  Among such automatic vacuum cleaners, there are models that can automatically start at a preset time and start cleaning in an unattended state.

  The conventional pyroelectric infrared sensor of the security device captures the heat of the automatic cleaner that operates in the unmanned state as described above, and detects it as an intrusion into the monitoring area formed on the floor surface. That is, the security device recognizes the automatic vacuum cleaner that operates in the monitoring area as a person who has entered the monitoring area, and transmits an erroneous notification to the monitoring center that an abnormality has been detected.

  In this way, when receiving an erroneous report indicating that an abnormality has been detected from the security device, the monitoring center issues an erroneous instruction to the monitoring area where the abnormality has been detected to the waiting guard, and Make false reports to related agencies such as the police and fire department.

  In order to solve such a problem, conventionally, when the automatic cleaner is operated in an unattended state, the monitoring area using the pyroelectric infrared sensor is set so as not to include the operation area of the automatic cleaner. I have to.

  However, setting the monitoring area using the pyroelectric infrared sensor so as not to include the operation area of the automatic cleaner has a serious problem in terms of security since the monitoring range is narrowed.

  The present invention has been made in view of the above, and can continue monitoring without narrowing the monitoring range even when a moving body such as an automatic vacuum cleaner is in operation, An object is to provide a security device that can suppress unnecessary dispatch.

  In order to solve the above-described problems and achieve the object, the security device of the present invention monitors the abnormality in the monitoring area using a spatial sensor that detects the entry of an object into the monitoring area including at least the floor surface. From the start of operation of the moving body to the end of operation determined from the operation status of the moving body detected by the detecting means And a monitoring control unit that cancels monitoring of the monitoring area by the monitoring unit.

  The security device according to the present invention provides a false alarm by releasing monitoring of a monitoring area by a pyroelectric infrared sensor that forms a monitoring area on a floor surface on which a moving body such as an automatic cleaner moves, while the moving body is in operation. It is possible to suppress unnecessary dispatches of security guards and the like due to.

  Here, FIG. 3 is a plan view showing the moving object detection unit 205 and the moving object system 400. FIG. 3A shows the moving body 401 set in the charging device 402 and in a charged state, and FIG. 3B shows the moving body 401 detached by the charging device 402 and in an operating state.

  As shown in FIG. 3, the main body 205 b of the moving body detection unit 205 provided in the moving body system 400 is, for example, a magnet sensor that detects attachment / detachment of the moving body (automatic vacuum cleaner) 401 to the charging device 402. The moving body detection unit 205 includes a magnet 205 a provided in the moving body (automatic vacuum cleaner) 401 and a charging device so that the moving body (automatic vacuum cleaner) 401 is in proximity to the magnet 205 a in a state where the charging body 402 is set. And a main body 205b provided at 402.

  The main body 205b includes a reed switch that allows current to flow through two contacts by the magnetism of the magnet 205a, and a semiconductor sensor using a Hall element or a magnetoresistive element. That is, the main body portion 205b detects attachment / detachment with the magnet 205a based on a change in the value of a current that flows in the presence or absence of a magnetic field.

  In addition, the main body unit 205 b includes a wireless unit 205 c that wirelessly connects to the security device 100. The main body unit 205b transmits information indicating the attachment / detachment state between the magnet 205a and the main body unit 205b to the security device 100 via the wireless unit 205c. In the present embodiment, the wireless unit 205c transmits information to the security device 100 by wireless communication. However, the present invention is not limited to this. For example, information transmission to the security device 100 may be performed by wire.

  As shown in FIG. 3A, when the magnet 205a and the main body 205b are close to each other, that is, when the moving body (automatic vacuum cleaner) 401 is set in the charging device 402 and is in a charged state, the main body The unit 205b transmits information indicating that the moving body (automatic vacuum cleaner) 401 is set to the charging device 402 to the security device 100 via the wireless unit 205c.

  As shown in FIG. 3B, when the magnet 205a and the main body 205b are separated from each other, that is, when the moving body (automatic vacuum cleaner) 401 is detached from the charging device 402 and is in an operating state, the main body The unit 205b transmits information indicating that the moving body (automatic vacuum cleaner) 401 is detached from the charging device 402 to the security device 100 via the wireless unit 205c.

  Here, the hardware configuration of the moving object detection unit 205 will be described. FIG. 4 is a block diagram illustrating a hardware configuration of the moving object detection unit 205. As shown in FIG. 4, the moving body detection unit 205 includes a control unit 205e and a storage unit 205d. The control unit 205e is configured by, for example, a CPU (Central Processing Unit). The CPU manages the current time using an internal clock. The storage unit 205d includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and stores various programs, parameters, and the like for the operation of the control unit 205e. The control unit 205e connects the main body unit 205b and the wireless unit 205c described above.

  The control unit 205e functions as a registration unit 205f and an operation time calculation unit 205g by operating according to the program stored in the storage unit 205d. The registration unit 205f registers in advance in the storage unit 205d an assumed operation time that is a time when the moving body (automatic vacuum cleaner) 401 is assumed to be operable based on the battery capacity. The operation time calculation unit 205g counts (calculates) the operation time of the moving object (automatic vacuum cleaner) 401 based on the internal clock. In the present embodiment, the moving body detection unit 205 includes the storage unit 205d and the operation time calculation unit 205g. However, the present invention is not limited to this. For example, the mobile unit detection unit 205 includes the storage unit 205d. Also good. As described above, when the security device 100 includes the storage unit 205d and the operation time calculation unit 205g, the mobile body detection unit 205 transmits the operation time of the mobile body (automatic vacuum cleaner) 401 to the security device 100. In addition, the moving body detection unit 205 may transmit the assumed operation time to the security device 100 via the registration unit 205f and store it in the storage unit 205d.

  The moving body detection unit 205 monitors whether the moving body (automatic vacuum cleaner) 401 is in operation or is set in the charging device 402 beyond the estimated operation time registered in the storage unit 205d in advance. When the moving body (automatic vacuum cleaner) 401 is operating beyond the estimated operating time, the mobile body detection unit 205 transmits information indicating that the mobile body (automatic vacuum cleaner) 401 is set in the charging device 402. To do. This is because even if the moving body (automatic vacuum cleaner) 401 cannot return to the charging device 402 due to some cause (battery exhaustion or the like), the moving body (automatic vacuum cleaner) 401 is not connected to the charging device 402. This is to ensure security by assuming that it is set to. In this case, the moving body (automatic vacuum cleaner) 401 does not move because the battery runs out, and the possibility of misreporting is extremely low.

  Next, the security device 100 will be described. The security device 100 is connected to the monitoring center 300 via a wired or wireless network 200. The security device 100 generally has a function of controlling warning or non-warning of the sensors 203 and 204 existing in the operation range of the moving body (automatic vacuum cleaner) 401.

  As shown in FIG. 2, the security device 100 according to the present embodiment includes a control unit 110, an input / output control unit 120, a communication control unit 130, and an operation panel 140.

  The control unit 110 performs overall control of the security device 100. The input / output control unit 120 is a processing unit that controls input / output of various data by input / output control of the sensors 203 and 204, the moving body detection unit 205, and the operation panel 140. The communication control unit 130 controls communication between the security device 100 and the network 200, and specifically corresponds to a network board or the like.

  The operation panel 140 displays information related to the security device 100 and inputs information to the security device 100. On the operation panel 140, for example, switching of the security state is input by pressing a button displayed on the operation panel 140, inputting a personal identification number, or the like. Further, the operation panel 140 sets an operation for each security state for the sensors 203 and 204. In addition, the operation panel 140 includes a speaker (not shown) and outputs a message, warning, and alerting sound to the user.

  In addition, the control unit 110 includes a detection information receiving unit 111, a moving body information receiving unit 112, an operation panel control unit 113, a monitoring unit 114, a monitoring control unit 115, a transmission / reception unit 116, and a guard state storage unit 117. And a sensor information database 118.

  The detection information receiving unit 111 receives detection information indicating that an abnormality transmitted by the sensors 203 and 204 has been detected and a sensor ID for identifying the sensors 203 and 204 that have transmitted the detection information.

  The mobile body information receiving unit 112 receives information on whether the mobile body (automatic vacuum cleaner) 401 transmitted by the mobile body detection unit 205 is operating or is set in the charging device 402.

  The operation panel control unit 113 controls the operation panel 140 such as sending display information and audio information to the operation panel 140 and acquiring input information input from the operation panel 140. In addition, operation panel control unit 113 accepts input of information stored in sensor information database 118 (see FIG. 5). Specifically, the operation panel control unit 113 receives an input of an operation for each security state with respect to each of the sensors 203 and 204. Here, the guard state includes an outing guard mode and a moving body guard mode.

  The outing security mode is a state in which an alarm is transmitted to the monitoring center 300 connected via the network 200 when the sensor 203 or 204 detects an abnormality when going out.

  The moving body operating security mode is a monitoring center connected via the network 200 when the moving body (automatic vacuum cleaner) 401 operates when going out, or when the predetermined sensors 203 and 204 detect an abnormality. In this state, an alarm is transmitted to 300.

  The security status storage unit 117 stores the current security status of the security device 100 (the outing security mode or the moving mode security mode). Specifically, the security state (outing security mode) input from the operation panel control unit 113, or the mobile body (automatic vacuum cleaner) 401 received by the mobile body information reception unit 112 is operating or the charging device 402. The security state (outing security mode or mobile object operation security mode) based on the information of whether it is set to is stored.

  The sensor information database 118 stores information about whether or not to send an alarm for each of the sensors 203 and 204 in each security state. Here, FIG. 5 is an explanatory diagram showing an example of the data configuration of the sensor information database 118. The sensor information database 118 stores a sensor ID, a sensor operation during outing guard, and a sensor operation during outing guard & moving body operation in association with each other.

  The sensor operation during outing security stores the operation when the sensors 203 and 204 detect an abnormality when the current security state stored in the security state storage unit 117 is “outing security mode”. As shown in FIG. 5, “warning” is normally stored in all sensor IDs. Thereby, even if any of the sensors 203 and 204 detects an abnormality, an alarm is notified and the alarm is transmitted to the monitoring center 300.

  For the sensor operation during going out & moving body operation, the operation when the sensors 203 and 204 detect an abnormality when the current security state stored in the security state storage unit 117 is the “mobile body operating security mode”. Is stored.

  As shown in FIG. 5, for example, when “alarm release” is stored in the sensor operation at the time of going out guard & moving body operation of the sensor ID “0001”, the sensor 203 (203a) of the sensor ID “0001” is abnormal. Even when a warning message is detected, a warning voice message or warning is not output from the operation panel 140 or an abnormality report is not sent to the monitoring center 300. This is because the sensor 203 (203a) forms a monitoring area on the floor surface, so that when the moving body (automatic vacuum cleaner) 401 operates, it captures the heat of the moving body (automatic vacuum cleaner) 401 and enters the monitoring area. This is to avoid detection.

  The sensor 203 (sensor 203b) indicated by the sensor ID “0002” is installed on the wall or the like of the house, forms a first auxiliary monitoring area above the floor surface, and the object to the first auxiliary monitoring area is formed. Since it is a shut-off sensor that detects intrusion, a warning voice message or alarm is always output from the operation panel 140 or an error is detected in the monitoring center 300 even if an abnormality is detected even in the “mobile body guard mode”. “Warning” is stored in the sensor operation when going out guard & moving body so as to make a report.

  In addition, since the sensor 204 indicated by the sensor ID “0003” is a boundary sensor that warns the boundary between a house such as a window and a door and the outside, when an abnormality is detected even in the “mobile body operating security mode” “Alert” is stored in the sensor operation during outing guard & moving body operation so that a warning voice message or alarm is always output from the operation panel 140 or alarm information is transmitted to the monitoring center 300.

  When the outing security mode is selected from the operation panel 140 and the current security state stored in the security state storage unit 117 is the “outing security mode”, the monitoring unit 114 performs the sensor operation during outing security in the sensor information database 118. Monitor abnormalities in the specified monitoring area.

  The monitoring control unit 115 receives information that the moving body (automatic vacuum cleaner) 401 is not set in the charging device 402 from the moving body detection unit 205 when the current security state is “outing security mode”. If it is determined that the operation of the (automatic vacuum cleaner) 401 has been started, the current security state stored in the security state storage unit 117 is switched from the “outing security mode” to the “mobile body operating security mode”. The monitoring control unit 115 includes the sensor 203 (of the monitoring in the monitoring unit 114 as defined in the sensor information database 118 corresponding to the “mobile body operating security mode”). Control is performed to cancel the monitoring of the monitoring area in step 203a).

  The transmission / reception unit 116 transmits / receives various information via the monitoring center 300 and the network 200. The transmission / reception unit 116 transmits alarm information from the monitoring unit 114 to the monitoring center 300 via the communication control unit 130.

  Next, a security process performed by the security device 100 configured as described above will be described. Here, FIG. 6 is a flowchart schematically showing the flow of security processing by the security device 100.

  As shown in FIG. 6, when the outing security mode is selected from the operation panel 140 and the current security state stored in the security state storage unit 117 is “outing security mode”, the monitoring unit 114 displays the “outing security mode”. As shown in the sensor operation at the time of outing security in the sensor information database 118 corresponding to “”, abnormalities in the monitoring area are monitored by all the sensors 203 and 204 (step S1).

  The monitoring control unit 115 receives information on whether the moving body (automatic vacuum cleaner) 401 is operating or is set in the charging device 402 under the monitoring in the “outing security mode”, and the moving body If it is determined that the (automatic vacuum cleaner) 401 has been operated (Yes in step S2), the monitoring unit 114 determines whether an abnormality is detected in any of the sensors 203 and 204 (step S3).

  If the monitoring control unit 115 determines that no abnormality has been detected (No in step S3), the monitoring control unit 115 changes the current security state stored in the security state storage unit 117 from the “outing security mode” to the “mobile body operating security mode”. "(Step S4).

  On the other hand, if the monitoring control unit 115 determines that an abnormality has been detected (Yes in step S3), the monitoring control unit 115 returns to step S1 and continues to be in “outing security mode” regardless of the operation of the mobile body (automatic vacuum cleaner) 401. Continue monitoring with.

  Subsequent to step S4, the monitoring control unit 115 is in the “outing security mode” as defined in the sensor operation database in the sensor information database 118 corresponding to the “mobile operation security mode”. Cancels monitoring of the monitoring area by the sensor 203 (203a) to be monitored. That is, the monitoring unit 114 monitors the abnormality in the monitoring area by the sensor 203 (sensor 203b) and the sensor 204 (step S5).

  When the monitoring unit 114 detects an abnormality, the transmission / reception unit 116 transmits alarm information from the monitoring unit 114 to the monitoring center 300.

  On the other hand, the monitoring control unit 115 receives information from the moving body detection unit 205 that the moving body (automatic vacuum cleaner) 401 is set in the charging device 402 under monitoring in the “mobile body operating security mode”. If it is determined that the operation of the mobile body (automatic vacuum cleaner) 401 has been completed (Yes in step S6), the current security state stored in the security state storage unit 117 is changed from “the mobile body operation security mode” to “ Switch to “outing security mode” (step S7) and return to step S1.

  As described above, according to the present embodiment, the mobile body (automatic cleaning) is transmitted based on the information about whether the mobile body (automatic vacuum cleaner) 401 sent from the mobile body detection unit 205 is operating or is set in the charging device 402. Machine) 401 is in operation, and the monitoring area of sensor 203 (203a) is a pyroelectric infrared sensor that forms a monitoring area on the floor surface on which the mobile body (automatic vacuum cleaner) 401 moves. The monitoring is canceled only while the moving body (automatic vacuum cleaner) 401 is operating. As a result, unnecessary dispatches such as guards due to misinformation can be suppressed. In addition, even when it is detected that the moving body (automatic vacuum cleaner) 401 is operating, monitoring by the sensor 203 (sensor 203b) and the sensor 204 is continued, so that the mobile body (automatic vacuum cleaner) Even when 401 is in operation, monitoring by the monitoring unit 114 can be continued without narrowing the monitoring range.
