Description

The present invention relates to an alarm system that notifies attention information corresponding to an abnormal situation in response to detection of an abnormal situation by an abnormality detecting unit.

The disaster prevention system described in Patent Document 1 includes an alarm signal receiving means for receiving an external alarm signal output from the outside of the monitoring area, and an abnormality signal output from the abnormality output device and an alarm output from the alarm signal receiving means. It is provided with a ringing sound control means for the receiver to ring the ringing device based on the signal. At that time, the ringing sound that sounds based on the abnormal signal and the ringing sound that sounds based on the alarm signal are different. Further, different ringing stop conditions are set according to the type of the alarm signal, and it is also possible to stop the alarm output through the operation of the touch panel or the switch.

The alarm device described in Patent Document 2 has a detection means for detecting an abnormal state of a detection target, an alarm output means for detecting an abnormal state and outputting an alarm, and an output state of the alarm output means as a standard power consumption state. The alarm output means is provided with an output state switching means that can be switched between the power saving state and a presence / absence information detecting means that automatically detects the presence / absence information indicating the existence or absence of a person, and the alarm output means is an output state based on the presence / absence information. The operation of the switching means is controlled. For example, if the presence / absence information indicates the absence of a person, the alarm sound is not emitted at all or is emitted at long intervals, and if there is a person, the alarm sound is emitted at short intervals. In this alarm device, regardless of the presence or absence of a person, the alarm output continues until the detecting means stops detecting the abnormal state.

In recent warning systems, other information (for example, weather information, shopping information, etc.) is also notified by using the notification function of the warning system that notifies an abnormal situation. In such an alarm system, the caution information to be notified to the user is a mixture of highly urgent information and less urgent information. In any case, the caution information needs to be noticed by a person, but once the person notices it, it is not necessary to notify the same caution information over and over again. If there is a person in the place where the caution information is notified, the purpose may be achieved by notifying at least once.

In the disaster prevention system according to Patent Document 1, the alarm output can be stopped by operating the touch panel or switch of the device body even while the alarm is being output, but the device body is out of reach of the user. If it is installed in the device or if the user does not know the installation location of the device main body, it takes time to stop the alarm output, which may cause an inconvenience that unnecessary notification is repeated.

Further, the alarm device according to Patent Document 2 is provided with presence / absence information detecting means for automatically detecting presence / absence information indicating the presence or absence of a person, and this presence / absence information is obtained in an alarm sound output mode (labor saving mode or standard mode). It is only used for switching. Therefore, once the notification is started, the notification is not automatically stopped, which may cause an inconvenience that unnecessary notification is repeated.

In view of the above circumstances, an object of the present invention is to provide an alarm system capable of automatically stopping the notification of caution information at an appropriate time.

The characteristic configuration of the alarm system according to the present invention is an abnormality detection unit that detects an abnormal situation, and a notification device that notifies attention information corresponding to the abnormal situation in response to the detection of the abnormal situation by the abnormality detection unit. The notification control unit includes a human detection sensor that detects the presence of a person in the peripheral region of the notification device, and a notification control unit that controls notification of the caution information by the notification device. The stop time of the notification is determined based on the time when a person is detected during the notification of the caution information by the notification device .
A notification importance assigning unit for assigning the importance to the caution information is provided, and the caution information is notified in a notification mode according to the importance.
The notification device is a buzzer or a speaker.
The notification mode is a mode in which the volume of the buzzer sound when the buzzer is notified or the volume of the message when the speaker is notified is made louder when the importance is high than when the importance is low .

Note that the notification of caution information in the present invention includes not only notification of highly urgent caution information such as fire alarm and gas leak alarm, but also non-urgent caution information such as weather information, traffic information, and living information. Notification is also included.

According to this configuration, the stop time of the notification of the abnormal situation is determined based on the time when the human detection sensor detects the presence of a person. Since the human detection sensor is configured to detect a person existing in the peripheral area of the notification device, when the presence of a person is detected by the human detection sensor while the attention information is being notified by the notification device. , It can be estimated that the person is receiving caution information. Therefore, this warning system can stop the notification of the caution information when it seems that the person is aware of the notification of the caution information.
Further, it is preferable that the attention information is provided with a notification importance assigning unit that assigns the importance to the caution information, and the caution information is notified in the notification mode according to the importance. According to this feature configuration, caution information is notified in an appropriate notification mode according to the importance of notification, so that appropriate notification according to the content of the caution information becomes possible. For example, the notification of highly urgent caution information can be performed at a loud volume or a large illuminance for a long time. On the contrary, the less urgent caution information can be notified at a low volume or low illuminance and for a short time.

As another feature configuration, a communication unit that receives communication information sent from the outside via a communication network is provided, and the communication unit transfers the communication information as caution information to the notification control unit. Suitable. According to this feature configuration, various information that the user wants to pay attention to, such as disaster information, weather information, and even shopping information, can be notified as caution information through the notification device, which increases the convenience of the user. ..

As yet another characteristic configuration, the caution information is notified a predetermined number of times from the time when the person detection sensor detects a person, or the caution information is notified for a predetermined time from the time when the person detection sensor detects a person. After the notification of the above is performed, the notification of the caution information is stopped. According to this feature configuration, when the notification device is a speaker and a voice message is emitted, the number of times the voice message is repeated is set to the number of times that it can be estimated that a person can recognize this caution information, and the notification is performed. When the device is a buzzer or a lamp and an alarm sound or an alarm light is emitted, a predetermined time can be set to a time at which it can be estimated that a person can recognize this caution information. As a result, in this warning system, the warning notification is stopped when it can be estimated that a person can recognize the content of the caution information regardless of the type of the notification device.

The good optimal construction, notice frequency of the high importance warning information, the importance is often set in comparison with the notice frequency of the low warning information, or notification time of the high importance care information, It is set longer than the notification time of the less important caution information. As a more specific example, it is preferable that less important caution information such as shopping information is notified only once, and more important caution information such as fire information is notified multiple times.

In this warning system, the notification of caution information is automatically stopped, but depending on the situation, it may be desired to forcibly stop the notification before the notification is automatically stopped. However, the main body of the alarm device, including the notification device, is often installed in a place that is difficult for humans to reach, such as near the ceiling, so as not to get in the way or to be noticed. Therefore, even if there is a manually operated stop button, its operation is not easy. In order to solve this problem, as another feature configuration of this warning system equipped with a human sensing sensor, a behavior pattern recognition unit that recognizes a human behavior pattern detected based on a sensing signal from the human sensing sensor is provided. It is preferable that the notification of the caution information by the notification device is forcibly stopped when the behavior pattern is regarded as a specific behavior pattern. According to this feature configuration, when a person performs a special behavior pattern (gesture) set for forcibly stopping the notification of caution information in the peripheral area of the notification device, the notification of caution information is forcibly stopped. .. This behavior pattern performed by a person does not have to be special, and may be any behavior that is not performed in daily life (for example, spinning a hand).

It is a schematic diagram explaining the basic configuration of an alarm system. It is an information flow chart explaining the flow of information in an alarm system. It is a flowchart which shows an example of the notification control in the notification control unit.

An embodiment of the warning system according to the present invention will be described with reference to the drawings.
FIG. 1 is a schematic diagram illustrating a basic configuration of an alarm system. The alarm device 1 for constructing this alarm system is arranged in the kitchen of a general household or the like, and notifies the user that an abnormal state such as a gas leak, incomplete combustion, or a fire has occurred. Further, the alarm device 1 receives communication information such as weather information and shopping information sent from the notification center 9 via the communication network via the router 60 in the home to call attention to the user. It is also possible to notify as information.

The alarm device 1 includes a notification control unit 2, a notification device 3, an abnormality detection unit 4, a human detection sensor 5, and a communication unit 6. The communication unit 6 receives communication information from the outside of the alarm device 1, converts it into a format that can be processed internally, and transfers the converted data to the notification control unit 2 as caution information for calling attention to the user.

The human detection sensor 5 sets the peripheral area of the notification device 3 as the detection target area. The human detection sensor 5 detects the presence or movement of a person using infrared rays, ultrasonic waves, visible light, or the like, and the detection result is sent to the notification control unit 2 as a detection signal. The detection signal from the human detection sensor 5 is handled as human detection data by the notification control unit 2. A structure may be adopted in which the human sensing sensor 5 is composed of an image sensor and the presence or absence of a person is confirmed by image processing.

The abnormality detection unit 4 includes a methane sensor that detects the methane concentration, a CO sensor that detects the concentration of carbon monoxide, a heat sensor that detects the room temperature, a smoke sensor that detects smoke, and the like. The detection signal from the abnormality detection unit 4 is sent to the notification control unit 2. The detection signal from the abnormality detection unit 4 is handled by the notification control unit 2 as a signal that is a source of caution information indicating the occurrence of an abnormal state such as gas leakage, incomplete combustion, or fire.

The notification control unit 2 sends a notification control signal to the notification device 3 in order to start and stop the notification of caution information. The notification device 3 notifies the user of attention information in a visual form or an auditory form based on the notification control signal. The notification device 3 is provided with at least one of a speaker 31, a buzzer 32, and a lamp 33. In this embodiment, the speaker 31, the buzzer 32, and the lamp 33 are all provided. A voice message sent from the notification center 9 and an artificial voice generated by the notification control unit 2 are played from the speaker 31. A known alarm sound is emitted from the buzzer 32. The lamp 33 functions as a warning light and blinks or lights up when an abnormality occurs.

The notification control unit 2 has a function of notifying the attention information in response to the detection result of the abnormality detection unit 4 or the reception of the caution information by the communication unit 6, and the human detection sensor 5 is the notification device 3. It is configured as a computer unit having a function of determining the stop time of the caution information based on the time when a person is detected during the notification of the caution information by. Specifically, if the notification device 3 that notifies the caution information is the speaker 31 that sends a message, the number of times the message is repeated is limited to a predetermined number of times from the time when the person detection sensor 5 detects a person. If the notification device 3 for notifying information is the buzzer 32 or the lamp 33, the notification time is limited to a predetermined time from the time when the human detection sensor 5 detects a person. The predetermined number of times and the predetermined time differ depending on the importance of the caution information to be notified.

The notification control unit 2 includes an input data processing unit 2A for inputting signals from the abnormality detection unit 4 and the human detection sensor 5, and an output data processing unit 2B for outputting a notification control signal to the notification device 3. Further, the notification control unit 2 is a functional unit substantially realized by executing a computer program, such as a notification importance allocation unit 21, a notification mode determination unit 22, a notification control signal generation unit 23, and a human detection processing unit 24. A behavior pattern recognition unit 25 and a notification forced stop unit 26 are included.

The contents of the functional unit constructed in the notification control unit 2 will be described with reference to the information flow diagram of FIG. The notification importance allocation unit 21 assigns the importance of the notification to the caution information based on the type of the caution information sent from the communication unit 6 or the input data processing unit 2A to the notification control unit 2. For example, when the caution information is weather information or shopping information, a low importance is assigned, and when the caution information is disaster information or gas leak information, a high importance is assigned. The caution information of high importance is repeatedly notified for a long time or a plurality of times so as to surely reach the user, and the caution information of low importance is notified only for a short time or once for the time being.

The notification mode determination unit 22 determines the notification method, that is, the notification mode, depending on the type of the notification device 3 that notifies the attention information and the importance of the caution information. The notification control signal generation unit 23 generates a notification signal and sends it to the notification device 3 so that the notification device 3 is driven in the notification mode determined by the notification mode determination unit 22. For example, when the gas leak information is notified by the buzzer 32, the buzzer sound is played at a medium volume. When the speaker 31 is used to notify the gas leak information of high importance by a message, the message is repeatedly played at a medium volume several times. When notifying fire information of high importance, a buzzer sounds at a loud volume and a message is continuously and repeatedly played at a loud volume. When the less important weather information is notified by a message, the message is repeated once or twice at a low volume.

The human detection processing unit 24 sets the peripheral area of the notification device 3, that is, the area where the notification from the notification device 3 can be confirmed, based on the human detection data converted into internal data from the human detection sensor 5 by the input data processing unit 2A. It is determined whether or not a person exists, and if a person exists, a determination result indicating the existence of the person is sent to the notification control signal generation unit 23. Further, when a person is detected, the human detection processing unit 24 analyzes the human detection data in a time series to generate behavior data indicating the behavior of the perceived person.

The behavior pattern recognition unit 25 calculates the behavior pattern from the behavior data generated by the human detection processing unit 24. When the calculated behavior pattern is regarded as a preset specific behavior pattern, the recognition confirmation is output. This specific behavior pattern corresponds to a gesture performed when the user wants to forcibly stop the notification of caution information. When the recognition confirmation of the specific behavior pattern is output from the behavior pattern recognition unit 25, the notification forced stop unit 26 issues a forced stop command to the notification control signal generation unit 23 to forcibly stop the notification of the caution information by the notification device 3. send. When the notification control signal generation unit 23 receives the forced stop command, the notification control signal generation unit 23 stops the notification of the caution information by the notification device 3.

The notification control signal generation unit 23 controls the start and stop of notification of caution information through the notification device 3. The notification is started at the timing when the caution information is input to the alarm device 1, and the notification is stopped in the following three stop modes.
(First stop mode) The notification mode is stopped based on the stop condition (first stop condition) attached to the notification mode determined by the notification mode determination unit 22. The first stop condition is basically a predetermined notification time or number of notifications according to the importance of the notification.
(Second stop mode) The person is stopped based on the stop condition (second stop condition) starting from the time when the determination result of the existence of a person is output from the person detection processing unit 24. At that time, the first stop condition is ignored. The caution information is notified until a predetermined time elapses from this starting point, or until the repetition of the notification reaches a predetermined number of times, and then the notification is stopped.
(Forced stop mode) The behavior pattern recognition unit 25 uses the behavior data output from the human detection processing unit 24 to determine the user's specific behavior pattern (bending / stretching / moving at a certain speed or higher, hand swinging) associated with the forced stop. Etc.), the notification forced stop unit 26 outputs a forced stop command. Upon receiving this forced stop command, the notification control signal generation unit 23 forcibly stops the notification of caution information by the notification device 3.

Next, an example of notification control in the notification control unit 2 configured as described above will be described with reference to the flowchart of FIG. When the notification control unit 2 is activated, the notification control routine and the human detection routine are started.

In the notification control routine, first, it is checked whether or not caution information is input (# 11). If no caution information has been entered (# 11 No branch), the notification flag is set to OFF (# 12). If caution information has been input (# 11Yes branch), the notification flag is set to ON (# 13). The importance of the caution information is determined based on the type of the input caution information (# 14). Further, the notification mode is determined based on the type and importance of the input caution information (# 15). Based on the determined notification mode, the notification control signal generation unit 23 generates a notification control signal (# 16) and outputs it to the notification device 3 (# 17). As a result, the notification of caution information is started (# 18). Further, based on the determined notification mode, the first stop condition, which is the stop condition for the notification of this caution information, is set in the notification control signal generation unit 23 (# 19). In this example, the first stop condition is the repetition of the caution message 10 times. That is, when the caution message is repeated 10 times, the notification is automatically stopped.

When the notification is started, it is checked whether or not the set first stop condition is satisfied (# 20). If the first stop condition is not satisfied (# 20 No branch), the process returns to step # 20. If the first stop condition is satisfied (# 20Yes branch), the first stop command is issued (# 21), and the notification of the warning information being executed is automatically stopped (# 100).

In the human detection routine, first, it is checked whether or not the notification flag is set to ON, that is, whether or not caution information is input (# 41). If the notification flag is set to OFF (# 41No branch), the process returns to step # 41. If the notification flag is set to ON (# 41Yes branch), it is further checked whether or not the human detection processing unit 24 determines that a person exists in the peripheral area of the abnormality detection unit 4 (# 42). .. If it is not determined that a person exists (# 42No branch), the process returns to step # 41. If it is determined that a person exists (# 42Yes branch), the notification control signal generation unit 23 is notified of the person existence determination result (# 43). When notified of the existence of a person, the notification control signal generation unit 23 sets a second stop condition (# 44) and waits for the second stop condition to be satisfied (# 44No branch). If the second stop condition is satisfied (# 44Yes branch), the second stop command is issued (# 46), and the notification of the running caution information is automatically stopped (# 100). If the first stop command is issued before the second stop command is issued, the human detection routine is canceled.

When it is determined in the check of step # 42 that a person exists (# 42Yes branch), the person existence determination result is also notified to the behavior pattern recognition unit 25 (# 51). The behavior pattern recognition unit 25 receives the human existence determination result, acquires the behavior data from the human detection processing unit 24 (# 52), and performs the recognition processing of the specific behavior pattern (# 53). When the specific behavior pattern is recognized (# 54Yes branch), it is considered that the user is making a gesture requesting the forced stop of the notification, and the forced stop command is sent to the notification control signal generation unit 23 (# 55). In response to this forced stop command, the notification control signal generation unit 23 forcibly stops the notification of the warning information being executed (# 100).
