Description

Technical Field

[0001] The present invention relates to the technology of intrusion prevention systems.

Background Art

[0002] Conventionally, the technology of systems for preventing the intrusion of a target person into a predetermined space has been known. For example, it is as described in Patent Document 1.

[0003] Patent Document 1 describes a gate device for infants to prevent infants from going out of a certain area. The gate device for infants is provided with a handle portion movable with respect to a door disposed at an entrance / exit, and is formed such that locking and unlocking of the door can be switched by moving the handle portion. In the gate device for infants, when unlocking the door, two operations of moving the handle portion in two directions are required.

[0004] According to the gate device for infants, by making the operation of unlocking the door difficult for infants, it is possible to prevent infants from passing through the entrance / exit. When the gate device for infants is installed in a desired area (for example, a kitchen, etc.), when an adult is working in the area, the door can be locked to prevent infants from entering the area.

[0005] However, when the gate device for infants is disposed on a passage that is a living traffic line such as an entrance / exit of a kitchen, it is necessary to perform an unlocking operation every time an adult passes through the passage. For this reason, there is a possibility of impairing the convenience when passing through the passage, and further improvement is desired.

Mode for Carrying Out the Invention

[0017] Hereinafter, the configuration of the intrusion prevention system 1 according to an embodiment of the present invention will be described.

[0018] The intrusion prevention system 1 shown in Fig. 1(a) can prevent a target person from entering a specific area when a specific operation (specific work) is being performed in a specific area (specific area). In this embodiment, as an example, the case where the target person for intrusion prevention is a child is assumed.

[0019] In this embodiment, an example in which the intrusion prevention system 1 is applied to a house 2 will be described. First, the house 2 will be described with reference to Fig. 2.

[0020] The house 2 has a plurality of rooms (areas). As the house 2, a detached house or an apartment house can be adopted. The house 2 has a kitchen 3. The kitchen 3 is an area equipped with facilities for cooking. In the kitchen 3, a system kitchen having a cooking heater 4, a storage unit 5 and a sink 6 is installed. The cooking heater 4 is used for cooking by heating. As the cooking heater 4, a gas stove, an IH heater, etc. can be adopted. The storage unit 5 stores cooking utensils such as knives and tableware. The storage unit 5 is provided with an openable and closable storage door 5a. The sink 6 is used for work using water. The sink 6 is provided with a faucet 6a capable of discharging water.

[0021] Also, the house 2 has a living room 7 (living and dining) which is an area adjacent to the kitchen 3. An intrusion prevention fence 30 described later is provided at a passage (the entrance and exit of the kitchen 3) for going back and forth between the kitchen 3 and the living room 7. Note that the areas provided in the house 2 are not limited to the above-described examples.

[0022] Next, the configuration of the intrusion prevention system 1 will be described. In the present embodiment, as an example, an example will be described in which a specific area is set to the kitchen 3 and a specific operation is set to a cooking operation by an adult (the parent of a child) in the kitchen 3. Here, the "cooking operation" in the present embodiment includes taking in and out of cooking utensils such as knives, and preparation and cleaning up of cooking such as washing. The setting of the specific area and the specific operation can be performed using a control unit 50 described later. The intrusion prevention system 1 includes a behavior detection unit 10, a work detection unit 20, an intrusion prevention fence 30, a notification unit 40, and a control unit 50.

[0023] The behavior detection unit 10 detects the behaviors of children and parents in the house 2. The behavior detection unit 10 includes a camera 11 and a microphone 12.

[0024] The camera 11 acquires video data captured through a predetermined lens unit. The camera 11 is installed at a place (for example, the ceiling, etc.) where people (children and parents) in the house 2 can be photographed.

[0025] The microphone 12 can acquire the sounds inside the house. The microphone 12 can acquire the voices of the people (parents in this embodiment) inside the house 2. The microphone 12 is installed at a location (such as the ceiling, etc.) where voices can be acquired inside the house 2.

[0026] The work detection unit 20 detects specific work in a specific area. In this embodiment, the work detection unit 20 is configured to be able to detect cooking work in the kitchen 3. The work detection unit 20 includes a heat sensor 21, an opening / closing sensor 22, and a flow sensor 23.

[0027] The heat sensor 21 detects the heat generated from a cooking appliance 4 or the like. The heat sensor 21 is installed at a location (such as the ceiling or wall, etc.) where the heat generated inside the kitchen 3 can be detected.

[0028] The opening / closing sensor 22 detects the opening and closing of the storage door 5a of the storage unit 5. The opening / closing sensor 22 is installed, for example, in the storage unit 5.

[0029] The flow sensor 23 detects the flow rate of the water discharged from the faucet 6a (the water used at the sink 6). The flow sensor 23 is installed at a location (such as the faucet 6a or the water pipe) where the flow rate of the above-mentioned water can be detected.

[0030] The intrusion prevention fence 30 can prevent children from entering a specific area (the kitchen 3). As shown in FIG. 2, the intrusion prevention fence 30 includes a door that can open and close the passage (the entrance / exit to the kitchen 3) for going back and forth between the kitchen 3 and the living room 7. Further, the intrusion prevention fence 30 includes an electronic lock 31 that can be switched between a locked state in which the door is held closed and an unlocked state in which the locked state is released and the door can be opened. When the electronic lock 31 is in the locked state, the entrance / exit of the kitchen 3 becomes impassable.

[0031] The electronic lock 31 is configured to be able to switch between a locked state and an unlocked state by performing a predetermined operation by an adult or a process of the control unit 50 described later (a process executed in the child-proof function). The operation method of the electronic lock 31 can adopt a method that is easy for an adult but difficult for a child. As the above operation method, for example, a method using an application of a terminal such as a smartphone owned by an adult (parent) can be adopted. Note that the operation of the electronic lock 31 is not limited to the operation using a terminal, and for example, an operation using a remote control or a button provided on the main body of the intrusion prevention fence 30 can be adopted.

[0032] The notification unit 40 performs notification to the notification target (the parent in this embodiment). The notification unit 40 performs notification by sound, for example. As the notification unit 40, for example, a device such as a buzzer can be adopted. Further, as the notification unit 40, a configuration in which notification can be stopped by a predetermined operation (for example, an operation using a button, an application, etc.) can be adopted. The notification unit 40 is installed at a place (for example, a wall, etc.) where notification can be executed within the house 2.

[0033] The behavior detection unit 10, the work detection unit 20, the intrusion prevention fence 30, and the notification unit 40 as described above may each be a separate device, or may be a device in which any one of the units (for example, the behavior detection unit 10 and the notification unit 40) is integrated. The above behavior detection unit 10, work detection unit 20, intrusion prevention fence 30, and notification unit 40 can be installed in the number required to preferably execute the process of the intrusion prevention system 1 (the intrusion prevention process described later).

[0034] The control unit 50 is capable of executing various types of information processing. The control unit 50 includes an arithmetic processing unit such as a CPU, and storage devices such as RAM and ROM. The control unit 50 can communicate with other devices (behavior detection unit 10, work detection unit 20, intrusion prevention fence 30, and notification unit 40) using an Internet line. As the control unit 50, a personal computer, a smartphone, a tablet terminal, etc. can be adopted. Also, the control unit 50 may be installed inside a house, or may be installed outside the house (for example, an external server, a cloud server, etc.).

[0035] The control unit 50 can acquire in real time the behavior information of the child and the parent obtained by the behavior detection unit 10. The above behavior information includes video data (video data) captured by the camera 11 and audio data (audio data) acquired by the microphone 12. Also, the control unit 50 can detect the behavior of the child and the parent using the acquired video data and the like. Note that the description of the mode of detecting the behavior of the child and the parent will be described later.

[0036] As described above, the configuration of the intrusion prevention system 1 has been explained. The intrusion prevention system 1 has a "child-proof function" that allows adults to pass through a specific area while preventing only children from passing through. When the child-proof function is on (being executed), the control unit 50 locks the electronic lock 31 of the intrusion prevention fence 30, and performs a process (discrimination process) of discriminating whether the person trying to pass through the entrance / exit of the specific area (kitchen 3) is an adult or a child. When an adult passes through, the control unit 50 automatically switches the electronic lock 31 to the unlocked state. The above discrimination process can be performed by the control unit 50 based on, for example, the video data captured by the camera 11.

[0037] The on / off switching of the child-proof function can be performed by the processing of the control unit 50 or by a predetermined operation by an adult (for example, an operation using a button, an application, etc.). When the child-proof function is off, the electronic lock 31 is in the unlocked state, and both adults and children can pass through the entrance / exit of the specific area.

[0038] When the child-proof function as described above is turned on, for example, when an adult is cooking in Kitchen 3, it is possible to prevent only children from entering Kitchen 3. However, in the case where the intrusion prevention fence 30 is arranged on a passage that serves as a living or housework flow line, such as the entrance / exit of Kitchen 3, and the child-proof function is always on, it is necessary to execute the discrimination process steps by the control unit 50 every time an adult passes through the above passage. Therefore, there is a possibility that the convenience when an adult passes through the above passage may be reduced.

[0039] Also, for example, when a child takes an action that requires care by an adult (a corresponding action described later), such as falling, in the living room 7 or the like during an adult's cooking, it is assumed that the adult in Kitchen 3 will rush to the child. In a state where the child-proof function is turned on, even in such a case, since it is necessary to execute the steps of the discrimination process, there is a possibility of impairing the convenience of passage when an adult rushes to the child.

[0040] Therefore, the intrusion prevention system 1 according to the present embodiment is configured to be able to execute "intrusion prevention processing" that can ensure the convenience of adult passage while preventing children from entering a specific area. When the intrusion prevention processing is being executed, when the control unit 50 detects a specific operation (cooking operation), it can execute a process of turning on the child-proof function and automatically preventing children from entering Kitchen 3. Further, in the intrusion prevention processing, when a child takes an action that requires care by an adult (the corresponding action) while the child-proof function is on, it is possible to execute a process of automatically switching the child-proof function off.

[0041] First, the mode of detecting the cooking operation (specific operation) by the control unit 50 will be described. The control unit 50 acquires the operation information obtained by the operation detection unit 20 and can detect a specific operation using the acquired detection result. Here, the operation information includes the detection results of the sensors (heat sensor 21, open / close sensor 22, and flow rate sensor 23) of the operation detection unit 20. When the control unit 50 detects at least one of the heat detection by the heat sensor 21, the open / close detection by the open / close sensor 22, and the flow rate detection by the flow rate sensor 23, it estimates that a cooking operation (specific operation) is being performed and detects the cooking operation.

[0042] Next, each process executed in the intrusion prevention process will be described using the flowchart of FIG. 3. The intrusion prevention process is repeatedly executed. The switching between the activation and deactivation of the intrusion prevention system 1 can be switched by the operation of an operator (for example, a parent). The above operation can be executed via the control unit 50.

[0043] In step S11, the control unit 50 turns off the child-proof function. In this state, the door of the intrusion prevention fence 30 can be opened. That is, it is possible to enter and exit the kitchen 3. After performing the process of step S11, the control unit 50 proceeds to the process of step S12.

[0044] In step S12, the control unit 50 starts acquiring the behavior information of the child by the behavior detection unit 10 and the operation information of the adult by the operation detection unit 20. After performing the process of step S12, the control unit 50 proceeds to the process of step S13.

[0045] In step S13, the control unit 50 determines whether or not it is during a specific operation (during a cooking operation) based on the operation information acquired in step S12. If the control unit 50 determines that it is during a specific operation (step S13: YES), it proceeds to the process of step S14. On the other hand, if the control unit 50 determines that it is not during a specific operation (step S13: NO), it proceeds to the process of step S18.

[0046] In step S14, the control unit 50 turns on the child-proof function. In this state, the control unit 50 locks the electronic lock 31 and, based on the result of the discrimination process, automatically switches the electronic lock 31 to the unlocked state only when an adult passes through the entrance / exit of the kitchen 3. Thereby, it is possible to prevent a child from entering the kitchen 3. After performing the process of step S14, the control unit 50 proceeds to the process of step S15.

[0047] In steps S15 and S16, the control unit 50 monitors the state of the child based on the child's action information (step S15) and determines whether the child is performing the corresponding action (step S16). Here, the "corresponding action" is a plurality of preset types of actions (such as falling, etc.) that correspond to actions that require care by an adult (parent). The "corresponding action" is set based on the child's action information and the parent's action information. As will be described later, in this embodiment, the "corresponding action" is determined by performing the "watching process" shown in FIGS. 4 to 7.

[0048] If the control unit 50 determines that the child is performing the corresponding action (step S16: YES), it proceeds to the process of step S17. On the other hand, if the control unit 50 determines that the child is not performing the corresponding action (step S16: NO), it temporarily terminates the intrusion prevention process. Note that the control unit 50 resumes the process from step S12 in the next intrusion prevention process.

[0049] In step S17, the control unit 50 switches to turn off the child-proof function. Thereby, regardless of the result of the discrimination process, the door of the intrusion prevention fence 30 can be opened. At this time, the control unit 50 can operate the notification unit 40 to issue an alert. Thereby, it is possible to notify the parent about the child's corresponding action. After performing the process of step S17, the control unit 50 temporarily terminates the intrusion prevention process. Note that the control unit 50 resumes the process from step S12 in the next intrusion prevention process.

[0050] Thus, after the process of step S12 is restarted, in the process of step S13, the control unit 50 determines whether a specific operation (cooking operation) is in progress. When it is determined that the specific operation is not in progress (step S13: NO), in step S18 where the process proceeds, the control unit 50 executes the same process as in step S17.

[0051] That is, in step S18, the control unit 50 turns off the child-proof function. Thus, for example, when the determination that a specific operation was in progress in the previous process of step S13 is changed to a determination that the specific operation is not in progress in the current process of step S13 (that is, when the parent's cooking operation is completed), the child-proof function is switched from on to off in the process of the current step S18. As a result, after the cooking operation is completed, anyone, not just adults, can enter the kitchen 3. If the child-proof function is already off at the time of the process of step S18, the off state is maintained as it is.

[0052] After performing the process of step S18, the control unit 50 temporarily ends the intrusion prevention process. In the next intrusion prevention process, the control unit 50 executes the process from step S12 again.

[0053] The intrusion prevention process has been described above. Note that the process according to this embodiment is an example, and the intrusion prevention process is not limited to the above-described example, and any process may be added or changed. Also, the specific examples shown in the above description are examples and can be arbitrarily changed.

[0054] By executing the intrusion prevention process as described above, for example, the child-proof function can be automatically turned on at the timing when cooking operations or the like are performed. Thereby, in a situation where it is desirable that children do not enter the kitchen 3, it is possible to prevent children from entering the kitchen 3. According to the present embodiment, when the cooking operation (specific operation) is not being performed, the child-proof function is turned off (the electronic lock 31 does not lock), so unlike the case where the child-proof function is always on, every time an adult passes through the entrance / exit of the kitchen 3, it is not necessary to execute the discrimination process steps by the control unit 50. Thereby, the convenience when an adult passes through the entrance / exit of the kitchen 3 can be improved.

[0055] Also, for example, when a child performs the corresponding action (e.g., falls) in the living room 7 or the like during the cooking of a parent (adult), it is assumed that the parent in the kitchen 3 will rush to the child. According to the present embodiment, when the control unit 50 detects the corresponding action of the child (step S16: YES), even if a specific operation (cooking operation) is being performed, the child-proof function can be switched off (step S17). Thereby, without executing the discrimination process steps by the control unit 50, the parent can leave the kitchen 3 and rush to the child, improving the convenience.

[0056] Also, as an example of a method for setting the "corresponding action" of a child, the intrusion prevention system 1 according to the present embodiment adopts a method of setting the corresponding action based on the learning result using the result of detecting the child's action and the result of detecting the parent's action. Specifically, the intrusion prevention system 1 sets the corresponding action by executing the "monitoring process" shown in FIGS. 4 to 7. The monitoring process learns the corresponding action of the child and detects the corresponding action using the result of detecting the child's action. Hereinafter, with reference to FIG. 1(b), the modes of detecting the actions of the child and the parent will be described.

[0057] First, the action detection for children will be described. The control unit 50 analyzes the video data of the camera 11 to perform the action detection of children. In this embodiment, the control unit 50 detects the actions of children in three patterns: "posture", "movement", and "behavior" based on the video data, and performs action detection based on each detection result. That is, in this embodiment, action detection is performed using the information obtained by subdividing the actions of children detected based on the video data.

[0058] Specifically, the control unit 50 detects the "posture" (what kind of posture) of the child by determining whether the child in the video data is lying down (recumbent), standing (standing position), or crawling (crawling).

[0059] In addition, the control unit 50 detects the "movement" (how the child is moving) of the child by determining the change in the height (ascending or descending) and the change in speed (fast or slow) of the child in the video data.

[0060] In addition, when the child in the video data holds an object, the control unit 50 detects the "behavior" (what the child is doing) of the child by determining whether the child simply holds the object (holding), the object leaves the hand (throwing), or the child puts the object in the mouth (eating).

[0061] The control unit 50 can detect the above actions using technologies such as motion capture. In addition, the control unit 50 can determine whether the person in the video data is a child or a parent (adult).

[0062] The control unit 50 can detect the actions of children (for example, running while holding an object in the mouth) based on the combination of the detection results of the above "posture", "movement", and "behavior". In addition, in the action detection of children, as the specific processing performed by the control unit 50, processing similar to the learning processing (Figs. 5 and 6) described later can be adopted.

[0063] Next, the action detection for the parent will be described. The control unit 50 analyzes the video data of the camera 11 and the audio data of the microphone 12 to perform the action detection of the parent. In the present embodiment, the control unit 50 detects the "movement" of the parent based on the video data and the "volume" of the parent based on the audio data, and performs the action detection based on each detection result.

[0064] Specifically, the control unit 50 detects the "stopping action" in which the parent stops the corresponding action of the child in the video data. The control unit 50 can detect the "stopping action" of the parent by the same technology as the above-described action detection of the child (for example, motion capture).

[0065] For example, in the video data, when the parent frames in from outside the frame at a high speed, the control unit 50 detects the "stopping action" that the parent rushed over. Also, when the posture of the child changes (for example, when the child falls), or when the posture of the child is returned to the original position, or when the child is picked up, the control unit 50 detects the "stopping action". Further, when the parent grabs the arm of the child, the control unit 50 detects the "stopping action" that the parent stopped the child's behavior. Note that the above-described detection modes of the "stopping action" are just examples, and the detection modes of the "stopping action" are not limited to the above-described examples, and various modes can be adopted.

[0066] In addition, the control unit 50 detects the "stopping volume" indicating that the parent scolded the child based on the audio data. The control unit 50 can distinguish the voice of the child and the voice of the parent and perform the detection of the "stopping volume". For example, if the volume of the parent's voice included in the audio data is equal to or greater than the preset normal voice volume, the control unit 50 determines that the parent scolded the child. Alternatively, if a predetermined pattern indicating that the parent scolded the child is included in the audio data, it may be determined that the parent scolded the child. Also, the audio data may be analyzed using technologies such as voice input (speech recognition) to determine that the parent scolded the child.

[0067] Based on the detection results of the above "restraining action" and "restraining volume", the control unit 50 can detect the actions of the parent (for example, running over, etc.). Hereinafter, among the detected actions of the parent, the actions that are "restraining action" or "restraining volume" are referred to as "restraining actions".

[0068] Hereinafter, with reference to FIGS. 4 to 7, the monitoring process will be described. The monitoring process is always executed while the intrusion prevention system 1 is activated.

[0069] In step S101 of FIG. 4, the control unit 50 turns on (operates) the camera 11 and the microphone 12. After performing the process of step S101, the control unit 50 proceeds to the processes from step S102 to step S106 and the processes from step S107 to step S111.

[0070] In the processes from step S102 to step S106, the control unit 50 executes processes related to detecting the actions of the child. Specifically, the control unit 50 detects the actions of the child based on the acquired video data (see FIG. 1(b)) and determines whether the detected actions of the child are "corresponding actions" (step S102, step S103).

[0071] Here, the "corresponding action" refers to the actions of the child that are restrained by the parent's "restraining action" among the detected actions of the child. The "corresponding action" is set based on the learning results in the learning process (step S111) described later and is stored in the control unit 50. In step S103, the "corresponding action" that has already been stored is compared with the actions of the child detected in step S102 to determine the "corresponding action".

[0072] When the control unit 50 determines that the child's behavior is the "corresponding behavior", it operates the notification unit 40 to issue an alert (step S103: YES, step S104). Thereby, it is possible to notify the parent of the child's corresponding behavior. Further, when the control unit 50 determines that the child's behavior is not the "corresponding behavior" (step S103: NO), it proceeds to the process of step S102.

[0073] After issuing the alert (step S104), the control unit 50 determines whether or not a "restraining action" has been detected based on the result of detecting the parent's action in step S107 (step S105). Note that the description of "detecting the parent's action" in step S107 will be described later.

[0074] When the control unit 50 determines that a "restraining action" has been detected, it ends the monitoring process (step S105: YES). Further, when the control unit 50 determines that a "restraining action" has not been detected, it proceeds to the relearning process (see FIG. 5) (step S105: NO, step S106). Note that the description of the relearning process will be described later.

[0075] Also, in the processes from step S107 to step S111, the control unit 50 executes processes related to detecting the parent's action. Specifically, the control unit 50 detects the parent's action based on the acquired video data and audio data (see FIG. 1(b)) and determines whether or not a "restraining action" has been detected (step S107, step S108).

[0076] When the control unit 50 determines that a "stop action" has been detected, it checks the combination of the child's actions (step S108: YES, step S109). Here, the "combination of actions" is a combination of action patterns (first to third actions) determined in the learning process described later. The control unit 50 checks whether the combination of the child's actions (step S102) stopped by the parent's stop action (step S107) is the corresponding combination of actions already learned in the learning process described later. Also, when the control unit 50 determines that no "stop action" has been detected (step S108: NO), it proceeds to the process of step S107.

[0077] After the control unit 50 checks the combination of the above actions (step S109), it determines whether the combination is a new combination (step S110). That is, the control unit 50 determines whether the combination of each action checked in step S109 is a combination not yet stored in the learning process (not the corresponding combination of actions already stored).

[0078] When the control unit 50 determines that the combination of each action checked in step S109 is a new combination, it proceeds to the learning process (see FIGS. 3 and 4) (step S110: YES, step S111). Also, when the control unit 50 determines that the combination of each action checked in step S109 is not a new combination, it ends the monitoring process (step S110: NO).

[0079] Hereinafter, the learning process will be described with reference to FIGS. 5 and 6. The learning process is a process of learning the actions of the child stopped by the parent's stop action as the corresponding actions. The learning process is executed based on the result of the child's action detection in step S102 and the result of the parent's action detection in step S107.

[0080] In the learning process, based on the results of the child's action detection (video data), the control unit 50 determines (analyzes) the information subdivided into three patterns of the child's posture (first action), movement (second action), and behavior (third action), respectively, turns on each flag of the action based on the determination result (such as the lying position flag), and performs the learning of the corresponding action based on the combination of the above flags. Here, "turning on the flag" means that in the subsequent process (step S225), the condition for determining that a certain action is being taken (for example, in a lying posture) is satisfied.

[0081] First, the control unit 50 performs processing related to the child's first action (steps S201 to S204). Here, the "first action" is an action related to the child's posture.

[0082] In step S201, the control unit 50 reads out the information related to the child's posture from the video data and determines the child's posture (step S201). In this embodiment, the control unit 50 determines whether the child's posture is "lying down", "standing", or "crawling" based on the read information.

[0083] In step S202 where the control unit 50 transitions when it determines that the child is "lying down", it turns on the "lying position flag". Also, in step S203 where the control unit 50 transitions when it determines that the child is "standing", it turns on the "standing position flag". Further, in step S204 where the control unit 50 transitions when it determines that the child is "crawling", it turns on the "crawling flag".

[0084] After the control unit 50 executes the processing related to the above first action (steps S201 to S204), it performs processing related to the child's second action (steps S205 to S213). Here, the "second action" is an action related to the child's movement. In this embodiment, the control unit 50 reads out the information related to the child's movement from the video data (step S205) and, as processing related to the second action, determines the "height change" and "speed" of the child.

[0085] First, the determination of "height change" (Steps S206 to S209) will be described. In the present embodiment, based on the information read in Step S205, the control unit 50 determines the change in the position of the child in the y-direction (height direction) (Step S206). Specifically, the control unit 50 determines whether the position of the child in the y-direction is "no change", "ascended (+y direction)", or "descended (-y direction)".

[0086] In Step S207 where the control unit 50 transitions when it determines that the position of the child in the y-direction is "no change", it sets "no flag" (does not turn on the flag). Also, in Step S208 where the control unit 50 transitions when it determines that the position of the child in the y-direction is "ascended (+y direction)", it turns on the "ascending flag". Further, in Step S209 where the control unit 50 transitions when it determines that the position of the child in the y-direction is "descended (-y direction)", it turns on the "descending flag".

[0087] Next, the determination of "speed" (Steps S210 to S213) will be described. In the present embodiment, based on the information read in Step S205, the control unit 50 determines the change in the speed of the child's movement (horizontal direction) (Step S210). Specifically, the control unit 50 determines whether the moving speed of the child is "none (no movement) or normal speed", "faster than normal", or "slower than normal". The normal speed of the child is set in advance.

[0088] In Step S211 where the control unit 50 transitions when it determines that the moving speed of the child is "none (no movement) or normal speed", it sets "no flag" (does not turn on the flag). Also, in Step S212 where the control unit 50 transitions when it determines that the moving speed of the child is "faster than normal", it turns on the "high-speed flag". Further, in Step S213 where the control unit 50 transitions when it determines that the moving speed of the child is "slower than normal", it turns on the "low-speed flag".

[0089] After the control unit 50 executes the processing related to the above second action (steps S205 to S213), it performs processing related to the child's third action (steps S214 to S219). Here, the "third action" is an action related to the child's behavior.

[0090] In this embodiment, the control unit 50 reads information related to the child's behavior from the video data (step S214), and based on the read information, determines whether the child has an object (step S215).

[0091] Also, when the control unit 50 determines that the child has an object (step S215: YES), it determines the child's behavior (steps S216 to S219). Specifically, the control unit 50 determines whether the child "only has an object", "has released the object from the hand", or "has put the object in the mouth".

[0092] In step S217 where the control unit 50 transitions when it determines that the child "only has an object", it presumes that the child only holds the object and turns on the "held flag". Also, in step S218 where the control unit 50 transitions when it determines that "the object has left the hand", it presumes that the child has thrown the object and turns on the "thrown flag". Also, in step S219 where the control unit 50 transitions when it determines that "the object has been put in the mouth", it presumes that the child has eaten the object and turns on the "eaten flag".

[0093] Also, when the control unit 50 determines in step S215 that the child does not have an object (step S215: NO), it does not determine the child's behavior and proceeds to the processing of step S220.

[0094] After the control unit 50 executes the processing related to the above third action (steps S214 to S219), it performs processing related to the change in the child's posture (steps S220 to S224). Here, the "change in posture" is the change in the child's posture after the determination of the first action (step S201).

[0095] After performing the determination of the first action (step S201), the control unit 50 reads out information regarding the posture of the child from the video data at the timing, determines the posture of the child in the same manner as the determination of the first action (step S201), and determines whether there is a change in the posture (step S220).

[0096] Also, when the control unit 50 determines that there is a change in the posture (step S220: YES), it determines the change in the posture of the child (steps S221 to S224). Specifically, the control unit 50 determines whether the change in the posture of the child is from the lying position to the sitting or standing position, from the sitting or standing position to the lying position, or from the lying or sitting position to the standing position.

[0097] In step S222 where the control unit 50 transitions when it determines that the change in the posture of the child is from the lying position to the sitting or standing position, it estimates that the child has woken up and turns on the "wake-up flag". Also, in step S223 where the control unit 50 transitions when it determines that the change in the posture of the child is from the sitting or standing position to the lying position, it estimates that the child has fallen and turns on the "fall flag". Further, in step S224 where the control unit 50 transitions when it determines that the change in the posture of the child is from the lying or sitting position to the standing position, it estimates that the child has stood up and turns on the "stand-up flag".

[0098] Also, when the control unit 50 determines in step S220 that there is no change in the posture (step S220: NO), it does not determine the change in the posture of the child and proceeds to the process of step S225.

[0099] After the control unit 50 executes the processes related to the change in the above posture (Steps S221 to S224), it learns that the combination of flags (combination of action patterns) determined in each of the above processes is the corresponding action. For example, when a child is running while holding an object in their mouth, the control unit 50 learns that the combination of the determination results of each flag including the "high-speed flag" and the "eating flag" is the corresponding action. The control unit 50 stores the above learning result. By repeating such learning, data of the corresponding action is accumulated.

[0100] After the control unit 50 executes the process of Step S225, it releases (turns off) the flags that are turned on in each process. After the control unit 50 executes the process of Step S225, it ends the learning process.

[0101] Also, hereinafter, the relearning process will be described with reference to FIG. 7. The relearning process is a process of reviewing the setting of this corresponding action (hereinafter referred to as "this corresponding action") when, despite the corresponding action being detected, the stop action is not detected (Step S103: YES, Step S105: NO).

[0102] In Step S301, the control unit 50 checks the correspondence record. Here, the "correspondence record" is a record that relearning processing has already been performed for a certain corresponding action (specifically, the record performed in Step S303 described later). That is, in Step S301, the control unit 50 checks the record that relearning processing has already been performed for this corresponding action. After the control unit 50 executes the process of Step S301, it proceeds to the process of Step S302.

[0103] In Step S302, the control unit 50 determines whether there is no correspondence record. If the control unit 50 determines that there is no correspondence record (Step S302: YES), it proceeds to the process of Step S303. Also, if the control unit 50 determines that there is a correspondence record (Step S302: NO), it proceeds to the process of Step S304.

[0104] In step S303, the control unit 50 records the first correspondence. That is, the control unit 50 records that this is the first time the relearning process is performed for the corresponding action. After executing the process of step S303, the control unit 50 ends the relearning process.

[0105] Also, in step S304, the control unit 50 excludes the corresponding action from the learning results of the corresponding action by the learning process. That is, in the present embodiment, when the relearning process is the second time, the corresponding action (this corresponding action) that is the target of the relearning process is excluded. After executing the process of step S304, the control unit 50 ends the relearning process.

[0106] The monitoring process has been described above. Note that the process according to the present embodiment is an example, and the monitoring process is not limited to the above-described example, and any process may be added or changed. Also, the specific numerical values exemplified in the above description are examples and can be arbitrarily changed.

[0107] By executing the monitoring process as described above, the corresponding action of the child can be learned based on the detection result of the parent's stopping action, and the corresponding action of the child can be detected based on the learning result. That is, instead of the child's action, the parent's stopping action is used as a trigger for determining the corresponding action, and the corresponding action of the child can be indirectly detected. Thereby, the detection of the corresponding action according to the environment can be performed. Specifically, even when the child performs the same action (for example, falls), depending on the environment (for example, whether there is a cushion laid at the place), the above action may or may not be dangerous. In the present embodiment, by performing the learning of the corresponding action using the actual stopping action performed by the parent, it is possible to suppress the detection of the corresponding action in a situation that is actually not dangerous.

[0108] In addition, in this embodiment, by executing the learning process as described above, the actions of the child restrained by the parent's restraining action can be specifically identified in detail based on the combination of posture, movement (height and speed), and the judgment result of the action, and learning of the corresponding action can be performed. As a result, dangerous actions can be judged in detail. For example, even if the height of the child is the same, if it is a sitting position, it is not dangerous, but if it is a standing position, it is dangerous, or if it is not dangerous to hold an object in the mouth in a sitting position but is dangerous in a standing position, dangerous actions can be set to handle such cases.

[0109] In addition, in this embodiment, different from using information of people or articles with IDs or the like set in advance, it is possible to detect dangerous actions of third parties without IDs or the like, and residential facilities and fixtures.

[0110] Also, in this embodiment, by executing the relearning process, unnecessary corresponding actions can be automatically excluded according to changes in the situation. That is, when a predetermined period has elapsed since the intrusion prevention system 1 was installed, for example, when the child grows up or the environment inside the house changes, it is assumed that an action that was previously dangerous becomes not dangerous.

[0111] According to the intrusion prevention system 1 according to this embodiment, by performing the relearning process, when a situation where the parent's restraining action is not performed even though the corresponding action is detected is detected a predetermined number of times (twice in this embodiment) or more, it is presumed that the action is not dangerous, and the data of the corresponding action can be automatically excluded from the learning result. As a result, it is possible to suppress unnecessary notifications from being made.

[0112] According to the above-mentioned relearning process, for example, different from a case where a user (for example, a parent) inputs information indicating that the corresponding action is unnecessary and performs control (feedback) to reflect the information, or manually re-registers the learning result of the corresponding action, it is possible to automatically exclude unnecessary corresponding actions.

[0113] In this embodiment, by setting the above-mentioned predetermined number of times to a plurality of times (twice), when the parent was not watching the corresponding action or when the restraining action was not in time, the data of the corresponding action is not excluded just because the restraining action was not performed once. Note that the above-mentioned predetermined number of times is not limited to twice, and various values can be set.

[0114] By executing the above-mentioned "watching process", the intrusion prevention system 1 can set the corresponding action and control the intrusion prevention fence 30 in the intrusion prevention process based on the detection result of the corresponding action.

[0115] As described above, the intrusion prevention system 1 according to this embodiment An intrusion prevention fence 30 (intrusion prevention unit) that can be switched between a locked state that prevents passage through the entrance and exit of a specific area and an unlocked state that releases the locked state; A discrimination unit (control unit 50) that discriminates whether a person attempting to pass through the entrance and exit of the specific area is an adult (first target person) or a child (second target person different from the first target person); An intrusion prevention stop process (process for turning off the child-proof function) for setting the intrusion prevention fence 30 to the unlocked state, and setting the intrusion prevention fence 30 to the locked state. When the discrimination result of the discrimination unit (control unit 50) is an adult, the intrusion prevention fence 30 is switched to the unlocked state, while when the discrimination result of the discrimination unit (control unit 50) is a child, the intrusion prevention execution process (process for turning on the child-proof function) for maintaining the locked state of the intrusion prevention fence 30, and an intrusion prevention control unit (control unit 50) that can switch and execute; A work detection unit 20 (first information acquisition unit) that acquires information regarding the actions of the adult in the specific area (step S13); A specific action detection unit (control unit 50) that detects, based on the information acquired by the work detection unit 20, that the adult is taking a specific action (specific work) in the specific area; comprises The intrusion prevention control unit (control unit 50) When the specific action detection unit (control unit 50) detects the specific action, the intrusion prevention execution process (process for turning on the child-proof function) is executed (step S13: YES, step S14). When the specific action detection unit (control unit 50) does not detect the specific action, the intrusion prevention stop process (process for turning off the child-proof function) is executed (step S13: NO, step S11).

[0116] By configuring in this way, convenience can be improved. That is, when a parent (adult) is performing a specific task (for example, cooking), and it is desirable that a child does not enter a specific area (for example, Kitchen 3), the child-proof function can be automatically turned on to prevent the child from entering the specific area. According to the intrusion prevention system 1, when the specific task is not being performed, the child-proof function is turned off (the electronic lock 31 does not lock), so it is not necessary to execute the discrimination process steps by the control unit 50 every time passing through the entrance and exit of the specific area. Thereby, the convenience when an adult passes through the entrance and exit of the specific area can be improved.

[0117] Also, the intrusion prevention system 1 according to the present embodiment has an action detection unit 10 (second information acquisition unit) that acquires information regarding the actions of the child (step S12), and a corresponding action detection unit (control unit 50) that detects, based on the information acquired by the action detection unit 10, that the child has taken a corresponding action (action requiring care) that requires care by the adult (step S16). It is equipped with and the intrusion prevention control unit (control unit 50) is capable of executing the intrusion prevention stop process (process for turning off the child-proof function) when the intrusion prevention execution process (process for turning on the child-proof function) is being executed and the corresponding action detection unit (control unit 50) detects the corresponding action (action requiring care).

[0118] By configuring in this way, for example, when a child performs a corresponding action (e.g., falls) outside a specific area (e.g., Living Room 7) during a specific operation of an adult (parent), it is assumed that the parent in the specific area will rush to the child. According to the intrusion prevention system 1, when a corresponding action of the child is detected, even if a specific operation is being performed, the child-proof function can be switched off. Thereby, without executing the discrimination processing steps by the control unit 50, the parent can leave the kitchen 3 and rush to the child, improving convenience.

[0119] Also, the intrusion prevention system 1 according to the present embodiment comprises a notification unit that performs notification when the care-required action detection unit (control unit 50) detects the corresponding action.

[0120] By configuring in this way, it is possible to notify that the child has performed the corresponding action.

[0121] The information acquired by the operation detection unit 20 includes at least one of the information on heat in the specific area, the information on opening and closing of the door of the storage unit installed in the specific area, and the information on the flow rate of water used in the specific area.

[0122] By configuring in this way, at least one of the information on heat, the information on opening and closing of the storage door 5a, and the information on opening and closing of the water flow rate can be used to suitably detect a specific action in the specific area.

[0123] Also, the intrusion prevention system 1 according to the present embodiment an action detection unit 10 (third information acquisition unit) that acquires information on the action outside the specific area of the parent (step S107), and a care action detection unit (control unit 50) that detects (step S108) that the parent has taken a preventive action (care action) to care for the child's action based on the information acquired by the action detection unit 10. The learning unit (control unit 50) stores a combination of the information on the stopping action detected by the care action detection unit (control unit 50) and the information on the action of the child who is the target of the stopping action, and learns the information on the action of the child as the corresponding action (steps S109 to S111). comprising The required care action detection unit (control unit 50) detects that the action of the child is the corresponding action when the information on the action of the child matches the corresponding action (step S103).

[0124] With this configuration, the corresponding action of the child can be suitably detected. That is, even for the same action of a child, the necessity of a stopping action may differ depending on the environment. In the intrusion prevention system 1 according to the present embodiment, instead of the action of the child, the parent's stopping action is used as a trigger for detecting the corresponding action, so that the corresponding action can be detected according to the environment. Thereby, it is possible to suppress the detection of the corresponding action in a situation where a stopping action is not actually required.

[0125] Note that the parent (adult) according to the present embodiment is an embodiment of the first subject according to the present invention. Also, the child according to the present embodiment is an embodiment of the second subject according to the present invention. Also, the action detection unit 10 according to the present embodiment is an embodiment of the second information acquisition unit and the third information acquisition unit. Also, the work detection unit 20 according to the present embodiment is an embodiment of the first information acquisition unit. Also, the intrusion prevention fence 30 according to the present embodiment is an embodiment of the intrusion prevention unit. Also, the control unit 50 according to the present embodiment is an embodiment of the discrimination unit, the intrusion prevention control unit, the required care action detection unit, the specific action detection unit, the care action detection unit, and the learning unit. Also, the thermal sensor 21 according to the present embodiment is an embodiment of the thermal information acquisition unit. Also, the opening / closing sensor 22 according to the present embodiment is an embodiment of the opening / closing information acquisition unit. In addition, the flow rate sensor 23 according to the present embodiment is an embodiment of an implementation of a flow rate information acquisition unit. In addition, the corresponding action according to the present embodiment is an embodiment of an implementation of a care-required action. In addition, the restraining action according to the present embodiment is an embodiment of an implementation of a care action. In addition, the specific work according to the present embodiment is an embodiment of an implementation of a specific action.

[0126] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above embodiments, and appropriate modifications can be made within the scope of the technical idea of the invention described in the claims.

[0127] For example, in the present embodiment, an example is shown in which when at least one of the detection of heat by the heat sensor 21, the detection of opening and closing by the opening / closing sensor 22, and the detection of flow rate by the flow rate sensor 23 is detected, a specific work (cooking work) is detected. However, the present invention is not limited to such a mode. For example, when detections of two or more of the above sensors are performed, or when detections of all the sensors are performed, a specific work (cooking work) may be detected.

[0128] In addition, in the present embodiment, an example is shown in which the specific area is set to the kitchen 3. However, the present invention is not limited to such a mode. For example, the specific area may be set to a bathroom or the like. In this case, a flow rate sensor 23 may be provided at the faucet in the bathroom, and when the detection by the flow rate sensor 23 is performed, a specific work (for example, a work of storing hot water in the bathtub, a work in the bathroom) may be detected. In this case, the intrusion prevention fence 30 may be disposed at the entrance of the bathroom to prevent children from entering the bathroom. In addition, the specific area is not limited to the kitchen 3 or the bathroom, and various areas within the house 2 can be adopted. In addition, the specific work is not limited to the cooking work or the work in the bathroom, and various works (actions) performed in the specific area can be adopted.

[0129] In addition, in this embodiment, as an example of the action detection unit 10, the camera 11 and the microphone 12 are illustrated, but the present invention is not limited to such a mode. As the action detection unit 10, various sensors and the like capable of acquiring information related to the actions of the target person (child), such as a motion sensor, can be adopted.

[0130] In addition, in this embodiment, as an example of the work detection unit 20, the thermal sensor 21, the open / close sensor 22, and the flow rate sensor 23 are illustrated, but the present invention is not limited to such a mode. As the work detection unit 20, various sensors and the like capable of acquiring information related to the actions (work) of the target person (parent) in a specific area, such as a camera, a microphone, a human presence sensor, and sensors capable of detecting the operation of equipment (such as cooking equipment) installed in a specific area, can be adopted.

[0131] In addition, in this embodiment, an example in which the camera 11, the microphone 12, and the notification unit 40 are installed on the ceiling, wall, etc. inside the house is shown, but the present invention is not limited to such a mode. For example, part or all of the camera 11, the microphone 12, the notification unit 40, and the control unit 50 may be realized by a terminal such as a smartphone owned by the parent. In this case, the parent can operate the terminal to perform operations on each part of the intrusion prevention system 1 (for example, an operation to stop the notification by the notification unit 40).

[0132] In addition, in this embodiment, an example in which the "stop action" is detected if either the "stop action" or the "stop volume" is included in the parent's action is shown, but the present invention is not limited to such a mode. For example, the "stop action" may be detected when both the "stop action" and the "stop volume" are included.

[0133] In addition, in this embodiment, an example in which the feedback of the detection result of the corresponding action and the re-registration of the learning result of the corresponding action are not performed by executing the re-learning process is shown, but the present invention is not limited to such a mode. For example, instead of or in addition to the re-learning process, a configuration capable of executing the above feedback and re-registration may be adopted.

[0134] In addition, in this embodiment, an example was shown in which the corresponding action is set based on the learning result using the result of the child's behavior detection and the result of the parent's behavior detection (by executing the "monitoring process"). However, the method for setting the corresponding action is not limited to the "monitoring process", and various methods can be adopted.

[0135] Also, in this embodiment, the target of intrusion prevention is a child, but it is not limited to such an example. For example, it is also possible to set a person in need of care, such as an elderly person, as the target of intrusion prevention.

[0136] In addition, in this embodiment, an example was shown in which the care-required behavior is set as the "corresponding action" and the care behavior is set as the "restraining action", but it is not limited to such an example. For example, the care behavior may be an action for assistance (nursing care) or the like, and the care-required behavior may be an action requiring assistance or the like.

[0137] Also, in this embodiment, an example was shown in which the intrusion prevention system 1 is applied to the house 2, but it is not limited to such an example. For example, the intrusion prevention system 1 can be applied to facilities such as kindergartens, nurseries, and schools. In this case, the intrusion prevention system 1 detects the care behavior of the staff of the facility. Also, in this case, the intrusion prevention system 1 may be configured to be able to identify a plurality of children and detect the corresponding actions of the identified children. Also, for example, the intrusion prevention system 1 may be applied to facilities such as elderly care facilities, nursing homes, and hospitals. In this case, the intrusion prevention system 1 detects the care behavior of the staff of the elderly care facility or the like.

[0138] In addition, the application target of the intrusion prevention system 1 is not limited to buildings. For example, it is also possible to apply the intrusion prevention system 1 to a vehicle. In this case, the vehicle door can be set as the intrusion prevention part, and the specific area can be set to the space outside the vehicle. Also in this case, each part (such as the behavior detection part 10 and the operation detection part 20, etc.) constituting the intrusion prevention system 1 is installed in the vehicle. According to the above configuration, when a specific operation is being performed outside the vehicle, the child-proof function is turned on to prevent children from getting out of the vehicle, and when a child inside the vehicle performs the corresponding behavior, the child-proof function is switched off, thereby improving the convenience when the parent rushes to the child inside the vehicle.
