FIG. 4 is a block diagram showing a configuration of an emergency call device used in the safety confirmation device according to the present invention. FIG. 4 is a block diagram showing a configuration of the safety determination device used in the safety confirmation device.
[0017]
As shown in FIG. 1, the safety confirmation device of the present invention includes a plurality of sound sensors 12 a to 12 f inside and outside a residence 11, a behavior monitoring device 13 connected to outputs of the sound sensors 12 a to 12 f, and the behavior monitoring device 13. The safety determination device 14 connected to the output of the safety determination device 14, the emergency notification device 15 connected to the output of the safety determination device 14, and the public line communication network 16 connected to the output of the emergency notification device 15.
[0018]
The sound sensor 12a is disposed outside the residence 11, and the sound sensors 12b to 12f are disposed at the entrance, living room, bedroom, kitchen, bathroom, toilet, hallway, and the like inside the residence 11.
[0019]
The sound sensors 12a to 12f are for detecting sounds in and around the arranged rooms. The sound sensor 12 detects sounds generated when a resident is acting in the house 11, and the action monitoring device. 13 is supplied.
[0020]
The sound sensors 12a to 12f have individual identification numbers, and when a sound is detected, the identification number signal and the detected sound signal are output.
[0021]
The behavior monitoring device 13 monitors the behavior of residents in the residence 11 based on the detection sounds from the sound sensors 12a to 12f, and the sound sensors 12a to 12f are connected to each other as shown in FIG. A data input interface 21, a CPU 22 which is a microprocessor to which the output of the data input interface 21 is connected, and an action monitoring memory 23 which is a nonvolatile memory connected to the CPU 22. The CPU 22 will be described later. It is configured to be connected to an output terminal 24 connected to the safety determination device 14.
[0022]
The data input interface 21 is an interface for outputting a sound signal and an identification number signal detected by the sound sensors 12 a to 12 f to the CPU 22.
[0023]
The CPU 22 takes in the identification number signal output from the sound sensors 12a to 12f and the detected sound signal via the data input interface 21, and detects the detected sound comprising the detected sound generation location, the sound content, and the detection time. Data is generated and stored in the behavior monitoring memory 23 and transferred from the output terminal 24 to the safety determination device 14 described later.
[0024]
The CPU 22 has a clock function, a recognition of identification number signals of the sound sensors 12a to 12f, and a function of analyzing detected sounds. That is, the sound signal and the identification number signal detected by the sound sensors 12a to 12f are obtained by the CPU 22 with the sound detection time, the sound generation location (set from the identification number of the sound sensor 12), and the analysis result of the generated sound. Is generated and stored in the behavior monitoring memory 23.
[0025]
The detected sound data each time the sound sensors 12 a to 12 f generated by the behavior monitoring device 13 detect a sound are transferred to the safety determination device 14.
[0026]
As shown in FIG. 3, the safety determination device 14 includes a CPU 32 connected to the behavior monitoring device 13 via the input terminal 31, a safety confirmation memory 33, and an output terminal for connecting the output of the CPU 32 to the emergency notification device 15. It consists of 34.
[0027]
The CPU 32 of the safety determination device 14 compares the detected sound data output from the behavior monitoring device 13 with the behavior pattern data stored in the safety confirmation memory 33 in advance, and the detected sound data is the behavior pattern data. If it is different from the above, it is determined that an abnormality has occurred, and the abnormality occurrence data is output to the emergency call device 15.
[0028]
This behavior pattern data is a pattern of the daily behavior of the resident based on the detected sound data transmitted from the behavior monitoring device 13.
[0029]
For example, the behavior pattern data is formed by patterning behaviors for several days and reviewing the behavior patterns every one to several weeks, for example, to generate the latest behavior pattern of the resident at normal times.
[0030]
The comparison between the detected sound data and the action pattern data is, for example, that the bedtime in the bedroom and the time when the user wakes up from bedtime are substantially the same time, and the actions such as before sleeping, during sleeping, and when waking up from bedtime are almost the same every day. The sound generated by the action is also substantially the same. From this, when the normal action is performed, the sound detected in the bedroom can be almost specified. The behavior pattern data generated by the data such as the sound detection location detected by the resident's normal life, the analysis content of the detected sound, and the sound detection time are compared with the detected sound data sequentially generated by the behavior monitoring device 13. By doing so, it is determined whether the resident is performing a normal life.
[0031]
In addition, data such as sounds or abnormal sounds that occur rarely in normal life may be collected and analyzed and stored in the safety confirmation memory 33. For example, the sound of telephones and visitors, the sound of broken windows, entrances, kitchen doors, etc., or burning sounds other than kitchen gas ranges and heating stoves, etc. Try to judge behavior.
[0032]
Furthermore, since there are acts such as preparing meals in the kitchen with the television set attached in the living room, the sound of multiple locations is analyzed to create a specific pattern of the resident's behavior.
[0033]
As shown in FIG. 4, the emergency call device 15 includes a CPU 42 having an input terminal 41 connected to the safety determination device 14, an emergency call voice data memory 43 connected to the CPU 42, and a telephone connected to the output of the CPU 42. The interface 44 and a public line connection terminal 45 are connected to the police and fire department via the public line communication network 16.
[0034]
When the abnormality occurrence data is supplied from the safety determination device 14, the CPU 42 of the emergency call device 15 reads out the emergency call data corresponding to the abnormality occurrence data from the emergency call voice data memory 42, and the telephone interface 44 and the public line. The telephone is transmitted to the police or the fire department via the connection terminal 45 and the public line communication network 16.
[0035]
In this emergency call voice data memory 43, the telephone number data of the police and the fire department or the telephone numbers of the residents of the neighborhood, the local government, etc., and the abnormal contents, for example, the sound of burning other things other than the burning sound of the gas range or the stove, etc. Or, voice data of a transmission message corresponding to a breaking sound or the like of glass or a door is stored. From these data, a telephone number selection message corresponding to the abnormal content is selected, telephone number setting and voice conversion of the message are performed by the telephone interface 44, and the voice message is transmitted to the selected telephone number.
[0036]
As described above, the safety confirmation device of the present invention monitors the resident's behavior based on the sound generated in the normal life of the resident, and detects a sound that is different from the normal sound, and responds to the abnormal sound. An emergency message can be voice-contacted to an emergency contact using a public line, privacy during normal life is protected, and an emergency contact can be made promptly to a predetermined contact in an emergency.
[0037]
Next, another embodiment of the safety confirmation device according to the present invention will be described with reference to FIGS. In the description of the embodiment of the present invention described above, by using the CPUs 22, 32, and 42 for the behavior monitoring device 13, the safety determination device 14, and the emergency call device 15, respectively, the processing of the individual CPUs 22, 32, and 42 is performed. A relatively inexpensive CPU with low capacity can be used.
[0038]
On the other hand, this other embodiment is a safety confirmation device using a single CPU having a relatively high processing capability, and the configuration of this other embodiment will be described with reference to FIG.
[0039]
A plurality of sound sensors 51 a to 51 n provided at various installation locations in the residence are connected to a CPU 53 that is a microprocessor that performs drive control of the entire safety confirmation device. The sound sensors 51a to 51n detect sounds generated at the places where they are installed. The sound detection sensor interface 52 sequentially takes outputs from the sound sensors 51 a to 51 n at predetermined time intervals under the control of the CPU 53 and outputs them to the CPU 53.
[0040]
The CPU 53 is connected to a behavior monitoring memory 54, a safety confirmation memory 55, and an emergency notification data memory 56, which are nonvolatile memories. In the behavior monitoring memory 54, the sound sensors 51 a to 51 n detect and are supplied to the CPU 53 via the sound detection sensor interface 52, and the analysis result of the sound signal generated by the CPU 53 and the place where the analyzed sound signal is generated ( The detected sound data including the identification of the sound sensor 51 and the sound signal detection time is stored.
[0041]
The safety confirmation memory 55 stores action pattern data generated by aggregating detection sound data for several days stored in the action monitoring memory 54 by the CPU 53. This behavior pattern data includes sound generation location data generated when a resident is performing a normal action at each location in the residence, analysis data of sound generated at that location, and sound generation time data. That is, the behavior pattern data is obtained by patterning sounds generated at each location in the residence as time passes on the day.
[0042]
It should be noted that the safety confirmation memory 55 generates sound analysis data that is relatively difficult to generate in normal life, for example, the sound of breaking glass, the sound of falling objects, and the sound of burning objects, and rarely generated in normal life. Analysis data such as a telephone call or a caller's ringing tone may be stored, and a combination state of these various sound analysis data may be stored.
[0043]
The emergency call data memory 56 stores data such as emergency call destination information (for example, a telephone number of a police fire department), emergency call message information, and the like when an emergency call is necessary.
[0044]
The CPU 53 is connected to a public line communication network 58 via a public line interface 57.
[0045]
The control operation of the CPU 53 of the safety confirmation device having such a configuration will be described with reference to FIG. When the driving power source of the safety confirmation device is turned on in step S1, the clock function built in the CPU 53 starts operating in step S2. This clock function has two types of clocks: a function that clocks the current time and a function that clocks the drive control time interval of the sound detection sensor interface 52 for sequentially capturing detection sounds at predetermined time intervals from the sound sensors 51a to 51n. In step S2, a timer of a time measuring function for driving and controlling the sound detection sensor interface 52 is reset.
[0046]
After the timer reset in step S2, the CPU 53 controls the drive of the sound detection sensor interface 52 to sequentially capture and output the sound signals detected by the sound sensors 51a to 51n, and in step S3, the respective sound sensors 51a to 51n. The presence or absence of a sound signal is determined.
[0047]
If it is determined in step S3 that none of the sound sensors 51a to 51n has detected a sound signal, it is determined in step S10 whether or not the timer function reset in step S2 has timed out, and the time has not expired. In this case, the sound signal detection determination in step S3 is repeated.
[0048]
When it is determined in step S3 that there is a sensor that has detected the sound signal by the sound sensors 51a to 51n, the CPU 53 detects the identification signal of the sound sensor 51 that has detected the sound signal in step S4, and the sound is detected in step S5. The sound signal from the sound sensor 51 that detected the signal is detected by frequency analysis, for example, and the time when the sound signal is detected in step S6 is detected.
[0049]
Detection sound data is generated and stored in the behavior monitoring memory 54 by the detection processing in steps S4 to S6, and is compared with the behavior pattern data stored in the safety confirmation memory 55 in step S7.
[0050]
In the safety confirmation memory 55, as described above, the action pattern data including the analysis result of the sound signal generated when the resident of each of the sound sensors 51a to 51n is normally living, the generation time of the sound signal, and the like. It is remembered. A safety confirmation determination is performed by comparing this behavior pattern data with the detected sound data detected and generated in steps S4 to S6.
[0051]
Next, in step S8, it is determined whether there is abnormal sound data in which the result of the safety confirmation determination in step S7 is different from the behavior pattern data, and whether or not an abnormality has occurred, and it is determined that no abnormality has occurred with the same detected sound data as the behavior pattern data. Then, the process proceeds to step S10, and if it is determined that an abnormality has occurred with detection sound data different from the action pattern data, the CPU 53 reads the emergency call data from the emergency call data memory 56 in step S9, and the read emergency call data. Then, an emergency message is transmitted to the nearest police fire department via the public line interface 57 and the public line communication network 58.
[0052]
At the time of this emergency call, it is possible to select the report destination and the report message by identifying the abnormal contents from the difference contents or location of the action pattern data and the detected sound data.
[0053]
Next, in step S10, it is determined whether or not the time counting function reset by the timer in step S2 has timed up. If the time has not expired, the sound signal detection determination in step S3 is repeated and the time is up. In step S11, the CPU 53 creates and corrects the behavior pattern data in the safety confirmation memory 55. In step S12, the CPU 53 determines whether the creation and correction of the behavior pattern data is completed, and the creation and correction of the behavior pattern data is completed. If it is determined, the process returns to step S2, the timer is reset again, and the sound signal detection operation from the sound sensors 51a to 51n is performed again.
[0054]
That is, the sound signals detected by the sound sensors 51a to 51n are sequentially switched and output at predetermined time intervals by the sound detection sensor interface 52, and the sound signals detected by the sound sensors 51a to 51n are stored in the behavior monitoring memory 54 together with the life time. In addition, the detected sound signal is compared with the action pattern data stored in the safety confirmation memory 55, and when a sound signal different from the action pattern data is detected, it is determined that an abnormality has occurred. The emergency call data stored in the emergency call data memory 56 is used to make an emergency call. The behavior pattern data stored in the safety confirmation memory 55 is created based on the behavior of the resident generated from the sound detection data stored in the behavior monitoring memory 54, and this behavior pattern data is sequentially updated to the latest resident behavior. By performing the correction, the accuracy of the emergency determination is improved when the resident detects an action different from the normal time or a sound signal different from the normal time.
[0055]
As described above, the present invention is a sound sensor provided at a plurality of locations in a residence, and based on the sound generated by the resident in normal life in the residence, the behavior pattern of the resident is grasped, and this behavior pattern And the resident's life sound are compared, and if the resident's safety confirmation is executed, and if a sound different from the behavior pattern is detected, an emergency call will be automatically issued because there is a possibility that the resident may have an abnormality. It became feasible.
[0056]
【The invention's effect】
The safety confirmation device of the present invention does not leak resident behavior during normal life, privacy is protected, and emergency notification can be promptly transmitted to a predetermined contact when an emergency occurs to the resident, It has the effect of making it easy to check the safety of residents.
