Description

The present invention relates to a monitoring device, a monitoring program, and a monitoring system for a facility.

The facility is often provided with an area that restricts access to non-target persons. In facilities provided with such an area, a monitoring system for management is often constructed to prevent outsiders from entering the area. As a conventional monitoring system, an outsider who is trying to enter the area is recognized by detecting a personnel tag to be carried by the target person as a recording medium and identifying the moving direction of the person by two sensors. , There is one that emits an alarm (see, for example, Patent Document 1). These two sensors are transmissive optical sensors having a light emitting part and a light receiving part. The identification of the moving direction and the sounding of the alarm in this monitoring system are performed by the monitoring device.

Japanese Unexamined Patent Publication No. 2004-21310

The above-mentioned conventional monitoring system can provide information to people because it is necessary to restrict access to people other than the target person. The sounding of the alarm corresponds to the provision of information notifying that an outsider is about to enter the area.

The control contents required for the monitoring system are not always the same. For example, in the event of an emergency when a fire breaks out, it is desirable to provide appropriate information according to the location to the target person to whom information should be provided. This is because the information to be provided changes depending on the positional relationship with the place where the fire broke out. For this reason, it is important to provide appropriate information depending on the situation.

An object of the present invention is to provide a monitoring device, a monitoring program, and a monitoring system capable of providing appropriate information according to a situation.

The monitoring device according to the present invention blocks electromagnetic waves in a facility provided with a light emitting / receiving unit based on detection signals output by a plurality of light receivers for receiving electromagnetic waves emitted by one associated floodlight. A movement direction identification unit that specifies the movement direction of the detection target person, a status determination unit that determines the status of the facility based on the current time and at least one of the disasters, a status determined by the status determination unit, and a movement direction. A notification control unit that selects information to be provided to the detection target person based on the movement direction specified by the specific unit and controls the notification of the information to the detection target person using the notification unit provided in the facility. Be prepared.

The monitoring program according to the present invention blocks electromagnetic waves in a facility provided with a light emitting / receiving unit based on detection signals output by a plurality of light receivers for receiving electromagnetic waves emitted by one associated floodlight. The movement direction of the detection target person is specified, the situation of the facility is determined based on the current time and at least one of the disasters, and the detection is performed based on the situation determined by the facility and the movement direction specified by the detection target person. The information to be provided to the target person is selected, and the information processing device is made to execute the process of notifying the detection target person of the information by using the notification unit provided in the facility.

The monitoring system according to the present invention includes one or more floodlights and a plurality of receivers for receiving electromagnetic waves emitted by one associated floodlight, and receives the electromagnetic waves with a light emitting / receiving unit provided in the facility. The monitoring device includes a notification unit provided in the facility for providing information to the person to be detected, and a monitoring device that processes the detection signal output by the receiver and controls the information provision by the notification unit. Based on the detection signals output by each receiver, the movement direction identification unit that specifies the movement direction of the person to be detected that blocks electromagnetic waves, the current time, and the situation where the facility status is determined based on at least one of the disasters. Information to be provided to the detection target person is selected based on the judgment unit, the situation determined by the situation judgment unit, and the movement direction specified by the movement direction identification unit, and the information is notified to the detection target person using the notification unit.

Hereinafter, embodiments of the monitoring system according to the present invention and the monitoring device according to the present invention used for realizing the monitoring system will be described with reference to the drawings. It should be noted that the embodiments including the following modifications are examples, and the present invention is not limited to these embodiments.

Embodiment 1.
FIG. 1 is a diagram showing a configuration example of a notification system, which is a monitoring system according to the first embodiment of the present invention. The notification system 1 is a monitoring system constructed in a facility for providing information by detecting a person 5 passing through a passage a between walls 2. The monitoring device according to the present embodiment is applied to the notification system 1 as the control device 10.

In the notification system 1, as shown in FIG. 1, a notification unit 12 and a floodlight 13 are installed on one wall 2, and two receivers 14a and 14b are installed on the other wall 2. The floodlight 13 is a light source that irradiates electromagnetic waves, for example, infrared rays. The two receivers 14a and 14b are arranged for receiving the electromagnetic wave emitted from the floodlight 13. As a result, the one floodlight 13 and the two light receivers 14a and 14b form a light emitting / receiving unit 11 which is an optical sensor for specifying the moving direction of the person 5. Hereinafter, the receiver 14a is also referred to as "first receiver 14a," and the receiver 14b is also referred to as "second receiver 14b." When it is not necessary to limit it, it is referred to as "receiver 14". Further, the person 5 is hereinafter referred to as "detection target person 5". In addition, electromagnetic waves are hereinafter referred to as "infrared rays". Electromagnetic waves are not limited to infrared rays.

In the present embodiment, as shown in FIG. 1, infrared rays emitted from one floodlight 13 can be received by two receivers 14. This eliminates the need for a mechanism for preventing the infrared rays emitted from the other floodlights 13 from being received, and reduces the number of floodlights 13 to be installed, as compared with the case where the floodlights 13 are installed for each receiver 14. Because there are advantages.

The notification unit 12 is an information providing device including, for example, a speaker that emits sound. It is installed near the floodlight 13 in order to provide information to the detection target person 5 who has moved to block infrared rays. The notification unit 12 may be capable of visually providing information.

FIG. 2 is a diagram showing a functional configuration example of a control device which is a monitoring device according to the first embodiment of the present invention. As shown in FIG. 2, the control device 10 includes an alarm signal receiving unit 101, a status determination unit 102, a moving direction specifying unit 103, and a control unit 104 as functional configurations.

The alarm signal receiving unit 101 is a function for receiving an alarm signal transmitted from an external device. For example, it is a communication device that enables communication with an external device. The alarm signal received by the alarm signal receiving unit 101 is, for example, a message notifying the occurrence of an emergency in the facility or the convergence of the emergency. Examples of emergencies include the occurrence of a fire, flood warnings by the Japan Meteorological Agency, and announcement of various warnings such as tsunami warnings. The situation determination unit 102 determines the situation of the facility depending on whether or not an emergency is occurring. Here, the situation during which an emergency is occurring is referred to as an "emergency situation", and the other situations are referred to as a "normal situation". It should be noted that the situation does not have to be roughly divided into two situations depending on whether or not a disaster has occurred, or whether or not the disaster should be at least a period of caution. That is, the situation may be divided into three or more situations.

In addition, during the period when a disaster has occurred or the alarm for which a disaster has occurred is valid, the alarm sound existing in the sound converted into an electric signal is detected by a microphone (not shown) installed in the facility, and the situation. The determination may be made. Here, the alarm sound is the sound of an emergency bell in the facility, the sound of broadcasting in the hall, and the like.

Floods and tsunamis require people to move higher. In facilities where there is no safe place, it is necessary to move from the facility. Many people have this kind of knowledge. On the other hand, fires need to be evacuated in consideration of the place where they occur. However, most people may not know where the fire broke out, or even if they did, how to evacuate.

For this reason, in the case of a disaster such as a fire that occurs from a part of the facility, it is particularly required to provide appropriate information to the detection target person 5. Therefore, here, it is also meaningful to avoid confusion, and for the sake of convenience, only fire is assumed as a disaster that causes an emergency. It is assumed that the alarm signal includes, in addition to the type information indicating the type of emergency and the situation information indicating whether or not an emergency has occurred, the action information indicating the action to be taken by the detection target person 5. The behavior information can indicate the direction in which the detection target person 5 should move.

The moving direction specifying unit 103 is a function of processing the detection signals output by the two receivers 14a and 14b, respectively, to specify the moving direction of the detection target person 5. This specific result is output to the control unit 104.

FIG. 4 is a diagram illustrating a method of specifying a moving direction. FIG. 4A shows an example of changes in the detection signals output by the two photoreceivers 14a and 14b when the detection target person 5 moves in the direction of the arrow shown in FIG. FIG. 4B shows an example of changes in the detection signals output by the two receivers 14a and 14b when the detection target person 5 moves in the direction opposite to the arrow direction shown in FIG. Here, with reference to FIG. 4, a method of specifying the moving direction of the detection target person 5 by the moving direction specifying unit 103 will be specifically described.

Here, it is premised that the two photoreceivers 14a and 14b are arranged at relatively short intervals in the direction of movement assumed by the detection target person 5, that is, in the direction parallel to the arrow direction shown in FIG. .. It is assumed that the detection signals output by the two receivers 14a and 14b are H (High) when receiving infrared rays emitted from the floodlight 13 and L (Low) when the infrared rays are blocked.

When the detection target person 5 moves in the direction of the arrow shown in FIG. 1, as shown in FIG. 4A, after the detection signal of the first receiver 14a changes from H to L, the second receiver 14b The detection signal of is changed from H to L. “Δt” shown in FIG. 4A is from the change of the detection signal of the first receiver 14a from H to L to the change of the detection signal of the second receiver 14b from H to L. It is a time difference. After the detection signal of the second receiver 14b changes from H to L, the period in which both the first receiver 14a and the second receiver 14b output the detection signal of L continues based on the above premise. become. The period ends when the detection signal of the first receiver 14a changes from L to H. After the detection signal of the first receiver 14a changes from L to H, the detection signal of the second receiver 14b also changes from L to H. The time difference between the change of the detection signal of the first receiver 14a to H and the change of the detection signal of the second receiver 14b to H is usually the time difference Δt or a time close to the time difference Δt. ..

On the other hand, when the detection target person 5 moves in the direction opposite to the arrow direction shown in FIG. 1, the detection signal of the second receiver 14b temporarily changes from H to L as shown in FIG. 4 (b). After that, the detection signal of the first receiver 14a temporarily changes from H to L. “Δt” shown in FIG. 4 (b) is the detection signal of the first receiver 14a after the detection signal of the second receiver 14b changes from H to L, as in FIG. 4 (a). Is the time difference from H to L. After the detection signal of the first receiver 14a changes from H to L, the period in which both the first receiver 14a and the second receiver 14b output the detection signal of L continues according to the above premise. become. The period ends when the detection signal of the second receiver 14b changes from L to H. After the detection signal of the second receiver 14b changes from L to H, the detection signal of the first receiver 14a also changes from L to H. The time difference between the change of the detection signal of the second receiver 14b to H and the change of the detection signal of the second receiver 14b to H is usually the time difference Δt or a time close to the time difference Δt. ..

For this reason, the moving direction specifying unit 103 can be used by the detection target person 5 when, for example, the detection signals output by the first receiver 14a and the second receiver 14b both change from H to L. Specify the direction of movement. The moving direction is specified from the timing when the detection signals output by the first receiver 14a and the second receiver 14b change from H to L, respectively. As shown in FIG. 4A, when the detection signal of the first receiver 14a changes from H to L and then the detection signal of the second receiver 14b changes from H to L, the moving direction specifying unit 103 specifies that the moving direction of the detection target person 5 is the direction of the arrow shown in FIG. On the other hand, as shown in FIG. 4B, when the detection signal of the second receiver 14b changes from H to L and then the detection signal of the first receiver 14a changes from H to L, the moving direction The identification unit 103 identifies that the movement direction of the detection target person 5 is the direction opposite to the arrow direction shown in FIG.

When the movement direction specifying unit 103 specifies the moving direction of the detection target person 5, the movement direction specifying unit 103 notifies the control unit 104 of the identification result. The control unit 104 provides information using the notification unit 12 according to the situation determined by the situation determination unit 102, triggered by the notification of the movement direction from the movement direction specifying unit 103. Therefore, the notification unit 12 is arranged near the floodlight 13. The control unit 104 corresponds to the notification control unit in the present embodiment.

In an emergency situation, the situation determination unit 102 outputs the action information in the alarm signal to the control unit 104. As a result, in an emergency situation, the control unit 104 causes the notification unit 12 to notify different information depending on whether or not the specified movement direction matches the direction to be moved indicated by the action information. For example, when the moving direction matches the direction to be moved, a message such as "The evacuation direction is correct" or "Please evacuate without rushing" is emitted from the notification unit 12. On the contrary, if the moving direction does not match the direction to move, that is, if the detection target person 5 is moving in the opposite direction to the moving direction, "the evacuation direction is opposite" and "the evacuation direction is wrong". A message such as "Masu" or "A fire is occurring in the future" is emitted from the notification unit 12.

In a normal situation, the control unit 104 causes the notification unit 12 to emit a message according to, for example, the moving direction. For example, the notification unit 12 is made to emit a message notifying the location, equipment, tenant, etc. existing in the moving direction. When the light receiving / receiving unit 11 is installed near the position opening of the commercial facility, the control unit 104 sends a message such as "Thank you for visiting the store" to the detection target person 5 entering the commercial facility. You may make it sound. A message such as "Thank you for using the service" may be emitted to the notification unit 12 for the detection target person 5 emitted from the commercial facility. In this way, the control unit 104 selects and provides the information to be provided according to the situation and the moving direction.

When the light emitting / receiving unit 11 is installed near the entrance of the facility where the usage time zone is restricted, the control unit 104 causes the notification unit 12 to emit a sound according to the relationship between the usage time zone and the current time. May be different. For example, the situation may be classified according to whether or not the remaining time until the end time of use is within the set time, and the message to be emitted may be switched. Specifically, when the remaining time is within the set time, instead of the message such as "Thank you for coming to the store", the notification unit 12 sends a message such as "It will be unavailable soon" or "Please hurry". You may make it emit sound. For this reason, the situation may be classified by time zone according to the availability condition of the facility.

Depending on the facility, the number of people may change significantly depending on the time of day, or the place where many people are located may change. For example, it is expected that it will be difficult to use the elevator during times when there are many people. For this reason, the classification by time zone may be further combined with the classification by disaster.

As described above, in the present embodiment, information is provided according to the moving direction according to the situation by sounding a message. Therefore, it is possible to individually provide appropriate information to the detection target person 5 according to the situation and the movement direction. As a result, the detection target person 5 can easily and surely take an appropriate action according to the place where he / she is in an emergency situation. Under normal circumstances, it is possible to provide appropriate information according to the direction of movement. Therefore, the detection target person 5 can use the facility more comfortably and more safely.

The floodlight 13 irradiates infrared rays with the electric power supplied from the power source 20. A switch unit 21 is arranged between the power supply 20 and the floodlight 13. The control unit 104 controls the power supply from the power supply 20 to the floodlight 13 via the switch unit 21.

FIG. 3 is a diagram showing a hardware configuration example of a control device which is a monitoring device according to the first embodiment of the present invention. As shown in FIG. 3, the control device 10 includes a processing unit 31, a setting unit 32, and a display unit 33.

The processing unit 31 is a unit that processes various types of data. The setting unit 32 is an operation unit for inputting various data to the control device 10. Various settings, switching of operation modes, input of a message to be emitted to the notification unit 12, and the like can be performed by operating the setting unit 32. The operator provided in the setting unit 32 may include a jumper plug, a toggle switch, a rotary switch, and the like.

The display unit 33 makes it possible for the operator to confirm the operating state, setting contents, and the like of the control device 10. The display unit 33 may include an LED (light emitting diode), a 7-segment LED, a lamp, a liquid crystal display, or the like.

As shown in FIG. 3, the processing unit 31 includes an I / F (InterFace) unit 311, a storage unit 312, and a CPU (Central Processing Unit) unit 313. The I / F unit 311 includes various peripheral devices and a plurality of controllers for connecting to external devices. The light receiving / receiving unit 11, the notification unit 12, the setting unit 32, and the display unit 33 are all connected to the I / F unit 311.

The detection signals output by the two photoreceivers 14a and 14b are sampled by the I / F unit 311 and output to the CPU unit 313 as a digital value of the voltage value of the detection signal. The I / F unit 311 outputs the digital value of the detection signal to the CPU unit 313 at the set sampling cycle.

The CPU unit 313 includes, for example, a CPU and a memory for a work. The CPU reads the monitoring program 3121, which is an application program stored in the storage unit 312, into the memory and executes it. The above-mentioned situation determination unit 102, movement direction specifying unit 103, and control unit 104 are realized by the CPU executing the monitoring program 3121. This monitoring program 3121 corresponds to the monitoring program in the present embodiment.

The storage unit 312 is a non-volatile storage device. For example, it is an auxiliary storage device such as a flash memory or a hard disk device. The storage unit 312 may include a medium driving device or an external device. The external device may be capable of communicating via a network. The monitoring program 3121 may be stored in a medium driving device or a recording medium accessible to an external device.

FIG. 5 is a flowchart showing an example of monitoring processing. This monitoring process is a process realized by the CPU unit 313 executing the monitoring program 3121. Data reception is invoked to process the received data. As a result, the monitoring process is activated by capturing the detection signal output by the light emitting / receiving unit 11, that is, the two light receivers 14a and 14b, or by receiving the alarm signal. As a result, the monitoring process is executed in the sampling cycle of the detection signal even if the alarm signal is not received. Next, with reference to FIG. 5, this monitoring process will be described in detail. The CPU unit 313 is assumed as the main body that executes the process.

First, in step S11, the CPU unit 313 determines whether or not the alarm signal has been received. When the alarm signal receiving unit 101 receives the alarm signal, the determination in step S11 becomes YES, and the process proceeds to step S12. If the alarm signal has not been received, the determination in step S11 becomes NO, and the process proceeds to step S15.

In step S12, the CPU unit 313 determines whether or not the received alarm signal indicates the occurrence of an alarm, that is, the occurrence of a fire. If the alarm signal indicates the occurrence of a fire, the determination in step S12 becomes YES, and the process proceeds to step S13. If the alarm signal indicates that the fire has been extinguished, the determination in step S12 becomes NO, and the process proceeds to step S14.

In step S13, the CPU unit 313 sets an emergency situation. After the setting, the process proceeds to step S15. On the other hand, in step S14, the CPU unit 313 sets the normal situation. Even after the setting, the process proceeds to step S15.

In step S15, the CPU unit 313 determines whether or not a digital detection signal has been input. When the detection signal is output from the I / F unit 311, the determination in step S15 becomes YES, and the process proceeds to step S16. If the detection signal is not output by the I / F unit 311, the determination in step S15 becomes NO, and the monitoring process ends here.

In step S16, the CPU unit 313 also refers to the detection signal input in the past as necessary, and performs an analysis for specifying the moving direction of the detection target person 5. In the following step S17, the CPU unit 313 determines whether or not the moving direction can be specified as a result of the analysis. If the moving direction can be specified, the determination in step S17 becomes YES, and the process proceeds to step S18. If the moving direction cannot be specified, the determination in step S17 becomes NO, and the monitoring process ends here.

In step S16, the detection signal input in the past is referred to when the detection signals output by the light receivers 14a and 14b are both L. In that case, for example, first, it is confirmed whether or not the detection signals output by the light receivers 14a and 14b are both L. When it can be confirmed that both of these detection signals are not L, that is, when it can be confirmed that both of the detection signals are L because one of the detection signals has changed from H to L. Further, referring to the detection signal input in the past, it is confirmed which of the two receivers 14a and 14b is the first to change the detection signal from H to L. As shown in FIG. 4, the moving direction can be specified by confirming which of the two receivers 14a and 14b first changes the detection signal from H to L. If it can be confirmed that both of these detection signals are already L, the movement direction to be specified has already been specified, so the movement direction is not specified.

In step S18, the CPU unit 313 determines whether or not an emergency situation has been set. When an emergency situation is set, that is, when a fire is occurring, the determination in step S18 becomes YES and the process proceeds to step S19. When the emergency situation is not set, that is, when the normal situation is set, the determination in step S18 becomes NO and the process proceeds to step S22.

In step S19, the CPU unit 313 determines whether or not the moving direction is the approaching direction. If the specified moving direction coincides with the approaching direction, the determination in step S19 is YES, and the process proceeds to step S20. If the directions do not match, the determination in step S19 becomes NO, and the process proceeds to step S21. The approach direction is, for example, the arrow direction shown in FIG. As a result, here, it is assumed that there is a place to be notified in the direction of the arrow, that is, equipment, tenants, and the like.

In step S20, the CPU unit 313 regards the detection target person 5 moving in the approaching direction as an intruder and emits a notification to emit a message. After the notification, the monitoring process ends. On the other hand, in step S21, the CPU unit 313 notifies that the detection target person 5 moving in the opposite direction of the approach direction is regarded as an exit person and emits a message. After the notification, the monitoring process ends.

In this way, in an emergency situation, the above-mentioned information is individually provided by a message for supporting the appropriate evacuation according to the moving direction of the detection target person 5. Therefore, the detection target person 5 can perform more appropriate evacuation more quickly.

In step S22, the CPU unit 313 determines whether or not the moving direction is the approaching direction. If the specified moving direction coincides with the approaching direction, the determination in step S22 is YES, and the process proceeds to step S23. If the directions do not match, the determination in step S22 becomes NO, and the process proceeds to step S24.

In step S23, the CPU unit 313 regards the detection target person 5 moving in the approaching direction as an intruder and emits a notification to emit a message. After the notification, the monitoring process ends. On the other hand, in step S24, the CPU unit 313 notifies that the detection target person 5 moving in the opposite direction of the approach direction is regarded as an exit person and emits a message. After the notification, the monitoring process ends.

As described above, even in the normal situation, the information is individually provided by the different messages as described above according to the moving direction of the detection target person 5. Therefore, the detection target person 5 can use the facility more comfortably.

In the present embodiment, the light emitting / receiving unit 11 includes one floodlight 13 and two light receiving devices 14a and 14b. As a result, the two receivers 14a and 14b are associated with the same one floodlight 13, and are used for receiving infrared rays, which are electromagnetic waves emitted by the floodlight 13. However, the light receiving / receiving unit 11 is not limited to such a device. For example, the light emitting / receiving unit 11 may have three or more receivers 14 associated with one receiver 13. Further, the light emitting / receiving unit 11 may have a plurality of combinations including only one light receiving device 13 and one light receiving device 14 associated with the light receiving light of the infrared rays emitted by the light projecting device 13. It is necessary that at least two light receivers 14 are included in any of the light receiving and receiving units 11.

Embodiment 2.
In the first embodiment, it is assumed that information is provided to the detection target person 5 passing through the passage a. On the other hand, in the present embodiment, an area that restricts access other than the target person is assumed as the target area, and information is provided to the detection target person 5. In the present embodiment, there are many common parts with the above-described first embodiment. From this, the description will be focused on the portion different from the first embodiment.

FIG. 6 is a diagram showing a configuration example of the monitoring system according to the second embodiment of the present invention. FIG. 7 is a diagram illustrating an area where entry / exit is managed by the monitoring system according to the second embodiment of the present invention.

As shown in FIGS. 6 and 7, this monitoring system allows the detection target person 5 to enter and exit the section 70 provided with the three doors 71, which is a target area that restricts the entry of non-target persons. It was built to manage. As a result, entry / exit to / from the compartment 70 can be performed using any of the passages a to c.

The notification system 1 in the first embodiment is provided for each door 71. In order to manage the detection target person 5 entering and exiting the section 70, each notification system 1 has a card reader 61 for non-contactly reading the identification information recorded on the recording medium 65 carried by the detection target person 5. Has been added. Each door 71 is provided with a locking device 62 that prevents an outsider from opening the door 71. Hereinafter, the identification information will be referred to as an "ID" (IDentifier), and the recording medium 65 will be referred to as an "ID card 65". The card reader 61 corresponds to the information reading device according to the present embodiment.

The type of ID card 65 is not particularly limited. The ID card 65 may be a magnetic card, or may be a non-contact and autonomous ID transmission, that is, an ID card that can be transmitted without holding it up. Therefore, the type of the card reader 61 is not particularly limited. A device for biometric authentication may be adopted instead of the card reader 61.

When the card reader 61 reads the ID, each of the control devices 10a to 10c transmits the read ID to the management device 60 to request authentication. As a result, each of the control devices 10a to 10c temporarily unlocks the locking device 62 when authenticated, and enables the detection target person 5 to enter the compartment 70. Hereinafter, when it is not necessary to particularly limit the control devices 10a to 10c, the control devices 10a to 10c are referred to as "control device 10". In the present embodiment, each of the control device 10 and the management device 60 corresponds to a monitoring device.

FIG. 8 is a diagram showing a functional configuration example of the management device. FIG. 9 is a diagram showing a hardware configuration example of the management device.

As shown in FIG. 8, the management device 60 includes a communication unit 81, an alarm signal reception unit 82, a status determination unit 83, and a control unit 84 as functional configurations.

As shown in FIG. 9, the communication unit 81 is for communicating with the communication unit 95 mounted on each control device 10. The authentication request is transmitted from the communication unit 95 of each control device 10 and received by the communication unit 81.

The alarm signal receiving unit 82 is a communication device for receiving the alarm signal. The situation determination unit 83 has a functional configuration for determining and setting a situation based on an alarm signal received by the alarm signal receiving unit 82.

The control unit 84 has a functional configuration for managing each control device 10. As shown in FIG. 8, as a functional configuration, an authentication unit 841, an entry / exit management unit 842, and a notification control unit 843 are provided. Both the control unit 84 and the control unit 104 of each control device 10 correspond to the notification control unit in the present embodiment. Further, the control unit 84, more specifically, the entry / exit management unit 842 corresponds to the number counting unit.

The authentication unit 841 is a function that processes an authentication request from the control device 10 and performs authentication for confirming whether or not the ID included in the authentication request is valid. The entry / exit management unit 842 monitors the entry / exit of the detection target person 5 in the section 70, and makes it possible to confirm the number of detection target persons 5 in the section 70. The notification control unit 843 is a function for controlling the information to be notified according to the authentication result of the authentication request.

Each control device 10 regards the detection target person 5 moving in the direction of the arrow shown in FIG. 1 as an intruder entering the compartment 70, and exits the detection target person 5 moving in the opposite direction from the compartment 70. It is regarded as an exiter and the management device 60 is notified. Therefore, in steps S20, S21, S23, and S24 in the flowchart shown in FIG. 5, the specific result of the moving direction is also transmitted to the management device 60.

The management device 60 is equipped with an alarm signal receiving unit 82. Therefore, the status setting in each control device 10 is performed by the notification from the management device 60. The control unit 84 also controls for that purpose.

FIG. 10 is a diagram illustrating a configuration example of management information. This management information is information created or updated by the entry / exit management unit 842. It is updated every time the specific result of the movement direction is transmitted. Each line is entry / exit information indicating a specific result of the movement direction, that is, entry / exit of the detection target person 5 in the section 70. As a result, the management information is a collection of entry / exit information.

As shown in FIG. 10, each entry / exit information includes reception time, passage number, moving direction, and number of people entering the room. The reception time is, for example, the time when the control device 10 transmits the specific result. The passage number is information indicating the passage that the detection target person 5 has moved to enter / exit. The moving direction is information indicating that the moving direction of the detection target person 5 is either a direction of entering the compartment 70 or a direction of exiting the compartment 70. The number of people entering the room is information indicating the number of people to be detected 5 who are estimated to be in the section 70. In the present embodiment, by storing such management information, the number of people in the section 70 can be provided as information.

In the entry / exit information, information other than the number of people entering the room can be transmitted from each control device 10. For this reason, thereafter, the information transmitted from each control device 10 by specifying the moving direction is also referred to as "entrance / exit information".

In an emergency situation, it is usually necessary to evacuate the detection target person 5 in the section 70. For this reason, in the present embodiment, the set person is regarded as a rescue activator, and the number of people in the section 70 is provided as information. The notification control unit 843 is limited to rescue operators and provides the number of people as information. By providing this number of information, rescue workers will be able to determine whether or not it is necessary to identify who is in the compartment 70. Therefore, the burden on the rescue operator is reduced, and the rescue operator can take more efficient actions. It should be noted that it is possible to determine whether or not the person subject to the authentication request is a rescue activist by including data indicating whether or not the person is a rescue activist in the personal data for authentication. All the persons in the section 70 are the detection target persons 5 because they enter and exit through any of the passages a to c.

As shown in FIG. 9, the management device 60 includes a processing unit 90, a setting unit 91, and a display unit 92 in addition to the communication unit 81 and the alarm signal receiving unit 82 as a hardware configuration. The processing unit 90 realizes the situation determination unit 83 and the control unit 84. It includes a CPU unit 901, a clock unit 902, an I / F unit 903, and a storage unit 904.

The clock unit 902 measures various times including the current time. The I / F unit 903 is connected to the setting unit 91 and the display unit 92. As a result, various data including various settings can be input via the setting unit 91. Further, the display unit 92 allows the operator to confirm the state of the management device 60.

The CPU unit 901 includes, for example, a CPU and a memory for a work. The CPU reads the management program 9041, which is an application program stored in the storage unit 904, into the memory and executes it. The situation determination unit 83 and the control unit 84 described above are realized by the CPU executing the management program 9041. This management program 9041, together with the monitoring program 3121, corresponds to the monitoring program in the present embodiment.

The storage unit 904 is a non-volatile storage device. For example, it is an auxiliary storage device such as a flash memory or a hard disk device. The storage unit 904 may include a medium driving device or an external device. The external device may be capable of communicating via a network. The management program 9041 may be stored in a medium driving device or a recording medium accessible to an external device.

FIG. 11 is a diagram showing a functional configuration example of the control device according to the second embodiment of the present invention. FIG. 12 is a diagram showing a hardware configuration example of the control device according to the second embodiment of the present invention.

As described above, each control device 10 sets the status by the notification from the management device 60. Therefore, as shown in FIG. 11, the alarm signal receiving unit 101 is not mounted on each control device 10. A communication unit 95 is mounted in place of the alarm signal receiving unit 101. Further, the control unit 104 controls the locking device 62. Therefore, as shown in FIG. 12, a locking device 62 is connected to the I / F unit 311. The card reader 61 is also connected to the I / F unit 311. As a result, the CPU unit 313 controls the locking device 62 via the I / F unit 311 and inputs the ID read from the ID card 65 by the card reader 61 via the I / F unit 311.

FIG. 13 is a flowchart showing an example of management processing. This management process is a process realized by the CPU unit 901 executing the management program 9041. Similar to the above monitoring process, the data reception is activated to process the received data. As a result, the management process is activated by receiving an authentication request from any of the control devices 10, entry / exit information, or an alarm signal. Next, with reference to FIG. 13, this management process will be described in detail. The CPU unit 901 is assumed to be the main body that executes the process.

First, in step S31, the CPU unit 901 determines whether or not the alarm signal has been received. When the alarm signal receiving unit 82 receives the alarm signal, the determination in step S31 becomes YES, and the process proceeds to step S32. If the alarm signal has not been received, the determination in step S31 becomes NO, and the process proceeds to step S35.

In step S32, the CPU unit 901 determines whether or not the received alarm signal indicates the occurrence of an alarm, that is, the occurrence of a fire. If the alarm signal indicates the occurrence of a fire, the determination in step S32 becomes YES, and the process proceeds to step S33. If the alarm signal indicates that the fire has been extinguished, the determination in step S32 becomes NO, and the process proceeds to step S34.

In step S33, the CPU unit 901 sets the emergency situation and instructs each control device 10 to set the emergency situation. The action information included in the alarm signal is transmitted to each control device 10. After giving such an instruction, the process proceeds to step S35. On the other hand, in step S34, the CPU unit 901 sets the normal situation and instructs each control device 10 to set the normal information. Even after giving such an instruction, the process proceeds to step S35.

In step S35, the CPU unit 901 determines whether or not the entry / exit information has been received. When any of the control devices 10 transmits the entry / exit information, the determination in step S35 becomes YES, and the process proceeds to step S36. If none of the control devices 10 has transmitted entry / exit information, the determination in step S35 becomes NO, and the process proceeds to step S37.

In step S36, the CPU unit 901 updates the management information using the received entry / exit information. The number of people entering the room shall be a value obtained from the received entry / exit information and the contents of the last saved entry / exit information. After updating the management information in this way, the process proceeds to step S37.

In step S37, the CPU unit 901 determines whether or not the authentication request has been received. When any of the control devices 10 transmits the authentication request, the determination in step S37 becomes YES, and the process proceeds to step S38. If none of the control devices 10 has transmitted the authentication request, the determination in step S37 is NO, and the management process ends here.

In step S38, the CPU 901 authenticates to confirm whether or not the ID included in the authentication request is valid. In the following step S39, the CPU unit 901 determines whether or not it is in an emergency situation. When an emergency situation is set, the determination in step S39 becomes YES, and the process proceeds to step S40. When the emergency situation is not set, that is, when the normal situation is set, the determination in step S40 becomes NO, and the process proceeds to step S42.

In step S40, the CPU unit 901 determines whether or not the target person of the authentication request is confirmed as a rescue activator as a result of the authentication. If it can be confirmed that the subject is a rescue activist, the determination in step S40 becomes YES, and the process proceeds to step S41. If it cannot be confirmed that the subject is a rescue operator, the determination in step S40 becomes NO and the process proceeds to step S42.

In step S41, the CPU unit 901 confirms the number of people in the room by referring to the management information. In the following step S42, the CPU unit 901 transmits the confirmed number of people together with the authentication result to the control device 10 that has received the authentication request. After that, the management process ends.

If the target person cannot be authenticated, that fact is transmitted to the control device 10 as an authentication result. Even if the authentication can be performed, if the rescue operator cannot be confirmed, only the authentication result is transmitted to the control device 10. As a result, the number of rescue workers can only be confirmed.

FIG. 14 is a flowchart showing an example of the monitoring process according to the second embodiment of the present invention. In the present embodiment, following the flowchart shown in FIG. 5, in other words, after the processing of steps S20, S21, S23, or S24 is executed, the portion of the flowchart shown in FIG. 14 is executed. As a result, FIG. 14 shows only the addition from the first embodiment. Here, the explanation will be given focusing on the additional portion. The main body that executes the process is the CPU unit 313. As described above, in the processes of steps S20, S21, S23, and S24, the entry / exit information is also transmitted to the management device 60.

First, in step S51, the CPU unit 313 determines whether or not the ID has been read. When the card reader 61 reads the ID recorded on the ID card 65, the ID is input to the CPU unit 313 via the I / F unit 311. As a result, the determination in step S51 becomes YES, and the process proceeds to step S52. If the card reader 61 has not read the ID, the determination in step S51 is NO, and the monitoring process ends here.

In step S52, the CPU unit 313 transmits an authentication request based on the read ID to the management device 60. In the following step S53, the CPU unit 313 waits for receiving the authentication result from the management device 60, and determines whether or not the authentication has been performed. If authenticated, the determination in step S53 becomes YES, and the process proceeds to step S54. If the authentication is not performed, the determination in step S53 becomes NO and the process proceeds to step S58.

In step S58, the CPU unit 313 emits a warning sound indicating that the authentication could not be performed from the sound emitting unit of the card reader 61. After that, the monitoring process ends.

In step S54, the CPU unit 313 determines whether or not it is an emergency situation. When the emergency situation is set, the determination in step S54 is YES, and the process proceeds to step S55. When the emergency situation is not set, that is, when the normal situation is set, the determination in step S54 becomes NO and the process proceeds to step S57.

In step S55, the CPU unit 313 determines whether or not the authenticated detection target person 5 is a rescue target person. As described above, when the number of people is received from the management device 60 together with the authentication result, the determination in step S55 becomes YES and the process proceeds to step S56. When only the authentication result is received from the management device 60, the determination in step S55 becomes NO and the process proceeds to step S57.

In step S56, the CPU unit 313 emits a message notifying the number of people transmitted together with the authentication result from the notification unit 12. In the following step S57, the CPU unit 313 causes the locking device 62 to unlock. After that, the monitoring process ends.

In this way, the number of people in the compartment 70 is automatically communicated only to the rescue operator. As a result, we try not to provide information that is not necessarily appropriate for anyone other than rescue workers.

In the present embodiment, the number of people in the compartment 70 is counted using only the detection result of the detection target person 5 by the light emitting / receiving unit 11, but another sensor may be further combined. .. For example, the presence or absence of a person in the compartment 70 may be confirmed by using the result of imaging by an imaging device that captures the inside of the compartment 70. By combining such other sensors, it becomes possible to provide rescue workers with more accurate information.

Further, in the present embodiment, the control device 10 is prepared for each passage, and the management device 60 is prepared to control each control device 10. However, all the control devices 10 and the management devices 60 may be realized by one information processing device. For this reason, the number of information processing devices that realize the monitoring device according to the present embodiment is not particularly limited. The number of compartments that allow the monitoring device to control entry and exit, such as the number of rooms, is not limited to one.
