Here, “safety” is not limited to life or death and health, but relates to changes in the state of the person being monitored, and includes crime prevention, disaster detection, and the like. Furthermore, it does not exclude the use of marketing research purposes such as shopping behavior.

  FIG. 1 is a schematic diagram showing a configuration of an Internet safety remote monitoring system (hereinafter referred to as “the system 1” as appropriate). The system 1 is connected to the Internet 5 through a monitoring terminal 2 connected to the Internet 5, a safety remote monitoring server (hereinafter referred to as “server 4”), a supervisor terminal 6, and a mobile phone network 7. Mobile phone 8 included. Here, for the sake of explanation, the monitoring terminal 2, the supervisor terminal 6, and the mobile phone 8 are illustrated one by one, but a large number of terminals are actually managed.

  The monitoring terminal 2 includes a computer 21 that includes a well-known CPU 22, RAM 23, and ROM 24. The computer 21 is connected to passage sensors 30a, 30b, 30c, and 30d (hereinafter collectively referred to as the passage sensor 30) that constitute passage detection means via an interface 26. The computer 21 is connected to the router 28 and the modem 27 via the interface 25. A modem 27, which is an ADSL (Asymmetric Digital Subscriber Line) modem, is connected to a WWW (World Wide Web, hereinafter simply referred to as "Web") of the Internet 5 via an ISP (Internet Service Provider) (not shown) via a general telephone line. .). It is configured to be always connected to the server 4 which is a server computer on the WWW of the Internet 5 by link information such as a predetermined IP address. Of course, the line only needs to be connected to the Internet 5, and may be an ISDN line, an optical fiber line, a dedicated line, or the like. A server OS (Operating System) such as Linux (registered trademark) is installed in an HDD (Hard Disk Drive) 29 of the monitoring terminal 2. It functions as a server computer having transmission / reception means capable of communicating with a client computer via the Internet 5 by TCP / IP (Transmission Control Protocol / Internet Protocol) and HTTP (hyper Text Transfer Protocol) protocols.

  The passage sensors 30a to 30d are constituted by pyroelectric infrared passive sensors, and detect the passage of a person. Since pyroelectric infrared sensors are not inherently dependent on the wavelength of infrared rays, in this embodiment, a filter is attached to the sensor as a window material to narrow the band so that it reacts specifically to infrared rays emitted by humans. This prevents malfunctions caused by things other than people. Of course, the sensor may be of any configuration as long as the passage can be detected quantitatively, depending on the location, detection by photoelectric tube, detection by mechanical pressure, detection by image recognition, detection by magnetism or static electricity, etc. It is selected appropriately.

  In addition, the HDD 29 stores and stores the passage signals received from the passage sensors 30a to 30d as the detection signal data together with the location / time information. Alternatively, a communication program to be transmitted at any time is stored.

  FIG. 2 is a plan view showing a monitored person's home, which is a management area of the system 1. FIG. 2 shows the arrangement of the passage sensors 30a to 30d of the present embodiment. In the present embodiment, the passage sensor 30a is disposed in the bedroom a.

  The passage sensors 30a to 30d can transmit a passage signal to the interface. On the other hand, in the embodiment, since power is supplied from a dry battery or a rechargeable battery, no wiring is required, and the arrangement position can be easily changed. The passage sensors 30a to 30e are identified by a unique ID number, for example, 01 to 04, and are provided with a transmission device (not shown) that transmits the detected passage to the interface as a signal, and the interface 26 receives and transmits this signal. (Not shown).

  The safety remote monitoring server 4 shown in FIG. 1 includes a computer 41 having a well-known CPU 42, RAM 43, and ROM 44. The server 4 has a server OS installed and is configured as a server computer on the WWW. The monitoring terminal 2 also functions as a client computer using the monitoring terminal 2 that requests and receives data as a server. The server 4 controls the entire system 1 by a safety remote monitoring program 47 stored in a storage medium constituted by the HDD. The interface 45 includes a router and a modem (not shown), and is configured to be always connected to the monitoring terminal 2 on the WWW of the Internet 5 by a predetermined IP address via an ISP from an optical fiber line. The server 4 which is a server computer having the transmission / reception means monitors the detection signal of the monitored person in real time at the monitored person's home in the predetermined management area via the Internet 5 which is always connected. The server 4 can send and receive e-mails using SMTP and POP3 protocols. In FIG. 1, the server 4 is configured by one computer for the sake of explanation, but may be configured by a plurality of computers. That is, in addition to the WWW server, the functions can be distributed and configured by a plurality of computer groups including a CGI server, a Mail server, a FireWall, a Proxy server, a DNS server, a DataBase server, and the like.

  The computer 41 of the server 4 receives the signals of the passage sensors 30a to 30d transmitted from the monitoring terminal 2 via the Internet 5 as detection signal data in real time each time. The detection signal data is temporarily stored, and a detection history is generated from the detection signal data and stored.

  The detection history master file 46 stores a detection history as detection history storage means. The detection signal data stored in the HDD 29 that is a storage unit of the monitoring terminal 2 is transmitted to the server 4 sequentially or periodically. In the server 4, the unique ID number and passage time of the sensor 30 are edited in time series for each HDD 29 of the monitoring terminal 2 from the received detection signal data, and stored in the detection history master file 46 as a detection history for each date. The

  FIG. 4 is a diagram conceptually illustrating an example of detection history data stored and stored in the detection history master file 46. In the detection history master file 46, the ID of the monitoring terminal 2, the date and time of the data, the start time and the end time, the sensor ID, and the count are associated and stored as a relational database. Therefore, the date, time zone, and sensor can be specified for each monitoring terminal, and the count can be totaled to create data.

  FIG. 3 is a block diagram showing the configuration of the supervisor terminal 6. The supervisor terminal 6 includes a computer 61 having a known CPU 62, RAM 63, and ROM 64. The computer 61 is connected to a router 66 and a modem 67 which is an ADSL (Asymmetric Digital Subscriber Line) modem via an interface 65, and is connected to the Internet 5 via an ISP from a general telephone line (see FIG. 1). ).

  The computer 61 includes a monitoring program file 68 stored in an HDD configured as an external storage unit. The monitoring program file 68 includes, for example, an OS such as WINDOWS-XP (registered trademark) and a web browser such as Internet Explorer (registered trademark), and the monitor terminal 6 is connected to the Internet 5 using TCP / IP and HTTP protocols. It functions as a client computer having communicable transmission / reception means. And it is comprised so that it can always connect with the server 4 which is a server computer which exists in WWW by a predetermined IP address. Of course, the line is not limited, and an ISDN line, an optical fiber line, a dedicated line, or the like may be used as long as it can be connected to the Internet 5.

  The monitoring program file 68 includes a supervisor program in addition to the OS and the web browser. The supervisor program is, for example, a program executed on the web browser installed here, so-called plug-in software. For example, a program based on FLASH (registered trademark) is downloaded from the server 4 via the web, so that various processes can be performed on the browser. The safety remote monitoring method of the present invention is executed in the client supervisor terminal 6 by this supervisor program. The program is not limited to FLASH, but may be any program that can be downloaded to the client side and executed, such as JAVA Script (registered trademark) or VB Script (registered trademark). In such a configuration, when the server 4 is first accessed, a load is temporarily applied to the server 4 and the network. However, since the supervisor terminal 6 plays the role of an agent thereafter, the load on the server 4 and the network (Internet 5) is smaller than when the server 4 performs processing such as data creation by CGI or the like. Therefore, the total load on the server 4 is reduced, and the server 4 can connect and manage many clients (monitoring terminal 6). Details will be described later.

  The computer 61 includes a comparison data file 69, a monitoring data file 70, and a warning setting file 71 in addition to the monitoring program file 68 stored and stored in the HDD.

  FIG. 5 is a diagram conceptually showing the comparison data stored in the comparison data file 69. The comparison data file 69 has a preset count for each time zone set for each group. In FIG. 5, for example, “01” of “group” is displayed as “6”. The number of detections assumed in the time zone from “6 am to 7 am” is indicated as “3”. As described above, the number of detections of the designated sensor 30 for each time zone and the total thereof are set and stored for each group set in the warning setting described later. Similarly, the time zone “7” is set to “28” times, and the time zone “8” is set to “20” times. In group 01, other time zones marked with “*” indicate time zones that are not compared. The same settings are made for the groups 02, 03, and 04.

  FIG. 6 is a diagram conceptually showing the monitoring data stored in the monitoring data file 70. The monitoring data file 70 reads the requested date data from the detection history master and stores it as monitoring data for each group under the conditions set in the warning setting. For example, in group 01, it was extracted from the detection history that there were four detections in time zone “6”, 25 detections in time zone “7”, and 16 detections in time zone “8”. Yes.

  Other storage files (not shown) include other programs and temporary storage areas. Here, each file is shown as four for convenience, but these files may be collected in one HDD or may be further distributed, and the storage medium is configured by an EEPROM or the like in a portable terminal. It may be a thing.

  Further, as shown in FIG. 3, the supervisor terminal 6 is connected via an interface 72 from, for example, a display means including a display 73 having an LCD, an input means including a keyboard 74 and a mouse 75, and a printer 76 such as an inkjet printer. The output means is connected, and input / output with the computer 61 can be performed.

  Next, a safety remote monitoring method in the system 1 configured as described above will be described. 7 to 9 are flowcharts showing main processes of the monitoring terminal 2, the safety remote monitoring server 4 and the supervisor terminal 6 of the system 1, and are sequence charts showing data exchange among them.

  As shown in FIG. 7, the monitoring terminal 2 always receives a detection signal from the sensor 30, inputs the detection signal every time it is detected, and inputs the detection signal into the detection signal data file of the HDD 29 together with the sensor ID and time information. It accumulates as data (step (hereinafter “step” is abbreviated as “S”) 1). Then, it is determined whether or not it is a predetermined transmission time (S2). If it is the transmission time (S2: YES), the detection signal data stored in the detection signal data file of the HDD 29 is read, and the Internet 5 is accessed. Then, it is transmitted to the server 4 as detection signal data together with the ID of the monitoring terminal 2 (S3). This transmission time is set, for example, every 15 minutes. Note that, when a detection signal is input, it may be transmitted as needed, but can be determined as appropriate depending on the load of the line or server.

  The detection signal data transmitted from the monitoring terminal 2 is received by the server 4 and the detection signal data is input (S4). The server 4 generates a detection history from the input detection signal data and stores it in the detection history master file 46 (S6). Here, as shown in FIG. 4, the number of times of detection for each time zone is stored for each sensor, classified by date for each monitoring terminal 2. This operation is performed every time data is transmitted from the monitoring terminal 2, and is not performed in FIG. 7, but is performed in parallel with other processes thereafter.

  Subsequently, the server 4 waits for access from the supervisor terminal 6 as a web server (S7). From this state, the supervisor terminal 6 accesses the server (S20). More specifically, when a URL (Uniform Resource Locator) and an IP address are specified and accessed from the monitor terminal 6 by a web browser, the server 4 sends the requested html file to the monitor terminal 6. Send. Then, the user ID and password are entered from the keyboard 74 on the web page transmitted from the server 4 and displayed on the display 73 of the supervisor terminal 6, and a button on the screen is clicked by the mouse 75 of the supervisor terminal 6. Then, the user ID and password are encrypted and transmitted to the server 4.

  Next, the server 4 searches a user master file (not shown) by CGI (Common Gate Interface) or the like, and authenticates whether the access is made with the registered user ID and password (S8). If it is a regular access (S8: YES), the access is permitted and a supervisor program by FLASH (registered trademark) is uploaded to the supervisor terminal 6 (S9). At the same time, the supervisor terminal 6 downloads the supervisor program and plugs it into the web browser so that it can be executed on the web browser (S21).

  Subsequently, as shown in FIG. 8, the supervisor terminal 6 executes the downloaded supervisor program (S22). Thereafter, the processing in the supervisor terminal 6 from S23 to S31 is executed by this supervisor program. Accordingly, the server 4 simply transmits the requested detection history, and does not burden the server 4 itself with processing the data. Therefore, the server 4 is configured as a light system.

  On the other hand, when the supervisor program is executed (S22), first, the warning setting already set in the supervisor terminal 6 is read from the warning setting file 71. This is because the monitor program main body is commonly used by a plurality of monitor terminals 6, so that the latest program is downloaded each time. On the other hand, the warning setting is individually set in accordance with the behavior pattern of the monitored person, and since there are large individual differences, the contents set in the past on each of the monitoring terminals 6 side. Are stored in each warning setting file 71.

  Here, FIG. 14 is a diagram conceptually showing the stored contents of the warning setting file 71. The warning setting file stores a group ID that is a warning target, a sensor ID that is a warning detection location, and a time zone that is a warning target. In addition, link information is stored so that comparison data (see FIG. 5) of each time zone can be read. In addition, the average value of the comparison data in the selected time zone that is the criterion for abnormality determination is stored, and the set difference that is the criterion for determination is also stored as “warning difference”. In addition, in the conceptual diagram shown in FIG. 14, “reaction value” corresponding to the monitoring data used in the past comparison and “difference” corresponding to the difference are also displayed.

  Returning to FIG. 8 and continuing the description, the supervisor terminal 6 requests the server 4 for a detection history (S23). On the other hand, the server 4 is always waiting to receive a request for a detection history (S10), and when it is determined that a request for a detection history is received from the supervisor terminal 6 (S11: YES), the server 4 is requested. The detection history is read from the detection history master file 46 (S12), and the requested detection history is transmitted to the supervisor terminal 6 (S13).

  In the present embodiment, in the default setting, the previous day's data is transmitted as a detection history. The request for the detection history is specified here by “day” with data for one day as a unit and midnight, but may be specified in units of time.

  The detection history for one day transmitted from the server 4 is received by the supervisor terminal 6, and monitoring data is created therefrom (S24). The monitoring data is extracted based on the settings stored in the warning setting file 71 and the number of detections in the time zone to be compared. For example, in the warning setting set as the group 01 as shown in FIG. 6, the target time zone is 3 hours from 6am to 8am, and only the number of times of detection is extracted. The

  Subsequently, comparison data is read from the comparison data file 69 (S25). In the comparison data file 69 shown in FIG. 5, the number of detections serving as a criterion for determining whether or not there is an abnormality is preset in the time zone set in the warning setting. The comparison data file 69 stores a numerical standard as a criterion for determining whether or not there is an abnormality in a specified time zone for a specified group. In FIG. 5, 3 times at 6 am, 28 times at 7 am, and 20 times at 8 am, and the difference from the monitoring data is calculated based on this value. Further, the sum and arithmetic average of these three time zones are calculated and stored.

  Subsequently, a comparison step is performed (S26). In the comparison step, the monitoring data created in the procedure of S24 is compared with the comparison data read in the procedure of S25 to obtain a difference. The difference of the present embodiment is obtained by an average obtained by dividing the total number of detected time zones set by the designated group by the number of time zones. Here, the difference between the monitoring data and the comparison data is obtained as an average. That is, the positive difference and the negative difference for each time zone are canceled out. The absolute value of the average difference between the monitoring data and the comparison data is the difference here. Therefore, the numerical value of the difference is an unsigned numerical value.

  Subsequently, in the abnormality determination step (S27), the difference obtained in the comparison step (S26) is read out from the set difference set in advance and stored in the warning setting file 71. Determine whether or not.

  The abnormality determination step (S27) will be specifically described. As shown in the warning setting file 71 shown in FIG. 14, the abnormality determination is performed for each of the groups 01 to 04. For example, in the case of the group 01 named “getting up”, the monitoring time zone is “6, 7, 8”, and the monitoring data is “4, 4” as in the monitoring data file 70 shown in FIG. 25, 16 ". This number of detections is the number of detections detected only from the passage sensor 30a in the bedroom. This averages to “15”. On the other hand, like the comparison data file 69 shown in FIG. 5, the corresponding comparison data is “3, 28, 20”, and the average is “17”. Here, when the difference is obtained in the comparison step (S26), when the average of the comparison data is subtracted from the average of the detection data, 15−17 = −2. When the absolute value is taken, the difference is “2”. If it is determined in the abnormality determination step (S27) based on this difference, the “warning difference” that is the set difference shown in FIG. 14 is 10, so 2 <10, that is, the difference <the set difference. Not judged and not subject to warning.

  Next, when looking at the group 02 named “meal”, the time zone “11, 12, 13, 18, 19, 20” to be monitored is the time zone during which preparation of meals and meals are expected. It is. Sensors are targeted for “living room and kitchen”. The average of the monitoring data is 14, the average of the comparison data is 40, and the difference is 26. Since the set difference is 20, it is determined that the difference is greater than the set difference and is abnormal.

  The group 03 is named “holiday”, the time zone is “13-16”, and the sensor is “Japanese room”. Here, there is a high possibility of being in a Japanese-style room if it is a holiday, but there are many uncertain factors, so if the set difference is “50” and the average of the comparison data is “50”, whether the detection in the Japanese-style room exceeds 100 times Or, when it is not detected at all in the Japanese-style room, it is determined that the abnormality is detected. With such a setting, unnecessary warnings can be eliminated. In this example, the average of the monitoring data is 6 and the difference is 44. However, since the set difference is as large as 50, the difference is less than the set difference, and it is not determined as abnormal.

  On the other hand, the group 04 is named “going out” and covers all time zones and all sensors. The comparison data is 0, and the set difference is 1. Therefore, if any of the sensors is detected even once, it is immediately determined as abnormal. By setting in this way, this embodiment can also be used as a crime prevention mode.

  In this case, the set difference is given as an average value, and is compared with the difference calculated in the comparison step. When the difference is larger than the set difference, it is determined that there is an abnormality. In other words, since the comparison is based on the average value of the time zone, even if there is monitoring data that is significantly different from the comparison data set in a specific time zone, if the detected peak is simply shifted, it is not determined as abnormal There is. On the other hand, even if there is no relatively large difference, it may be determined as abnormal if a minus or plus difference accumulates.

  Note that the algorithm of the abnormality determination step (S27) can be changed as appropriate, and an abnormality may be detected with a different setting range for each time zone, or an abnormality may be determined only when the number of detections is small. Alternatively, weighting may be performed or data may be processed in advance. Furthermore, determination may be made by appropriately combining these.

  Next, the warning step will be described. If it is determined that there is an abnormality in the abnormality determination step (S27) (S28: YES), a warning is given to the supervisor by a predetermined warning means (S29). In the present embodiment, the warning means displays a warning screen 73b (see FIG. 16) on the display 73 of the supervisor terminal 6.

  Here, the screen displayed on the display 73 of the supervisor terminal 6 will be described. FIG. 15 shows a main screen 73 a of the screen display on the display 73 of the supervisor terminal 6. The main screen 73a is a basic screen when the supervisor program is executed (FIG. 8; S22). Here, the comparison data and the monitoring data are displayed as a 3D bar graph. This graph has a keyboard shape elongated in the front-rear direction (here referred to as “Z-axis direction”) divided by time zone in the horizontal direction of the screen (here “X-axis direction”) on the bottom surface. The monitoring data graph 81 displayed as a three-dimensional bar graph extending in the vertical direction (here, “Y-axis direction”) is displayed at the approximate center of each area 80. Further, a comparison data graph 82 is displayed adjacent to the screen 80 in the same time zone area 80 in the same manner as the monitoring data graph. Therefore, the monitoring data graph 81 and the comparison data graph 82 in the same time zone are configured to be easily compared at a glance. On the left side of the screen, a Y-axis scale 83 of the bar graph is displayed, and a numerical value corresponding to the scale of the scale is displayed. Here, “100” is displayed in the middle portion, and “200” is displayed on the upper scale. The upper scale is a text box 84, and the numerical value can be appropriately changed depending on the amount of monitoring data. For example, when the numerical value in the text box 84 is entered as 100, the intermediate value is automatically corrected to 50. Further, the height of the monitoring data graph 81 and the comparison data graph 82 are also changed in accordance with this scale.

  In the lower left of the screen, a “specified date” button 85 for changing the specified date of the monitoring data is displayed. When operated on the screen, the text is displayed in the order of year, month and day as “2004/10/14”. A box will appear where you can change the date. Further, a monthly and yearly calendar may be displayed and selected with the mouse 75.

  A sensor button 86 is displayed on the upper right of the main screen 73a. The sensor button 86 includes a bedroom 86a, a living room 86b, a Japanese-style room 86c, and a kitchen 86d, and a sensor for displaying the number of detections in the monitoring data graph 81 can be selected with a mouse.

That is, the monitoring data graph 81 displayed on the main screen 73a is displayed with the target to be displayed specified by the selection of the “designated date” button 85 and the sensor button 86.
Further, the display contents of the comparison data graph 82 are changed by the “one month average” button 87a, the “six month average” button 87b, and the “user setting” button. The “average for one month” button 87a sets an average value of detection histories for the past one month as comparison data. The “6-month average” button 87b similarly sets an average value for the past six months as comparison data. The “user setting” button is manually set manually by the user (monitor). The procedure for correcting the comparison data will be described later in detail.

  A time 88 is displayed on the monitoring data graph 81 side of the keyboard-like area 80. At time 88, numbers 0 to 23 indicating the time zone of the area 80 are displayed, for example, “0” in the midnight range. Further, by operating the “numerical value” button 89 at the lower right of the main screen 73 a, the numerical value 90 of the comparison data for that time period is further displayed as “average” before the time 88 in the area 80. At the same time, the numerical value 91 of the monitoring data is also written before the “numerical value” button 89 of the comparison data as “numerical value”. By displaying the numerical value 91 in this way, a difference that can be intuitively grasped from the monitoring data graph 81 and the comparison data graph 82 can be examined in detail.

  Here, returning to FIG. 9, the description of the flowchart will be continued. In the warning step (S29) shown in FIG. 9, a warning screen is displayed on the main screen 73a configured as described above. Here, FIG. 16 is a diagram showing a warning screen 73b. The warning screen 73b is displayed in a pop-up form in the main screen 73a. Here, “2:“ Meal ”warning” is displayed, the group number “2”, the group name “meal”, and a warning are displayed. The sensor selected by this group is displayed as “Sensor Living Kitchen”. Also, the time zone set in this group is displayed as “time 11 12 13 18 19 20”. Then, the average of the comparison data, the average of the monitoring data, the difference, and the set difference set as warnings in this group are displayed as “Past = 40 Today = 14 Difference = 26 Warning setting 20”. This display can be arbitrarily deleted after confirmation and returned to the main screen 73a.

  Here, in the warning step (S29), the content of the warning is HTTP-transmitted to the server 4 as a warning message. The server 4 receives this message using the HTTP protocol (S32), and electronically sends the message to the mobile phone 8 via the Internet 5 and the mobile phone network 7 via the SMTP (Simple Mail Transfer Protocol) server in the server 4. A mail is transmitted (S33). This e-mail is basically composed of text having the same contents as the warning screen 73b. Further, the mail address of the e-mail is stored in the customer master file (not shown) of the server 4 along with the data related to the monitor by a report from the monitor.

When it is determined that there is no abnormality in the abnormality determination step (S27) (S28: NO), the warning step (S29) is not executed and the warning screen 73b is not displayed.
Subsequently, after the warning step (S29) is executed or when it is determined that there is no abnormality in the abnormality determination step (S27) (S28: NO), a setting change step (S31) is executed. In the setting change step (S31), various settings are changed.

  Next, the setting change step (S31) will be described. FIG. 10 is a flowchart showing details of the setting change step (S31) of FIG. In the setting change step, when the “designated date” button 85 (see FIG. 15) is operated with the mouse 75 (see FIG. 3) (S311: YES), the monitoring date change process (S312) is executed and is performed on the screen. The monitoring date setting is changed. When the bedroom 86a, the living room 86b, the Japanese-style room 86c, and the kitchen 86d of the sensor button 86 on the main screen 73a (see FIG. 15) are operated with the mouse (S313: YES), a sensor change process (S314) is executed and operated. The total result of the sensor button 86 is displayed in the monitoring data graph 81 and the comparison data graph 82.

  When the “warning setting” button 92 displayed on the upper part of the main screen 73a shown in FIG. 15 is operated with the mouse 75 (S315: YES), a warning setting change process (S316) is executed.

  Here, the warning setting change process (S316) is a process in which the monitor terminal 6 causes the user to change the setting, which sensor is monitored in which time zone, and in which state the warning is issued. is there. FIG. 11 is a flowchart showing in detail the warning setting change process (S316). The warning setting change process (S316) shown in FIG. 10 will be described with reference to this flowchart. The warning setting change process includes warning settings (hereinafter referred to as “group settings”) set on the warning setting screen 73c for each group and other settings (hereinafter referred to as “common settings”) set on the main screen 73a common to the groups. .)

  Therefore, it is first determined whether or not the setting is a group setting (S600). If the setting is a group setting (S600: YES), the “warning setting” button 92 is operated. First, when the warning setting change process is started, the display is changed to the warning setting screen 73c. Here, FIG. 17 is a diagram showing a warning setting screen 73c. A group menu 95 configured as a pull-down menu is displayed at the bottom of this, and the supervisor selects an arbitrary group to be used as a control for changing the warning setting with a mouse from the displayed plurality of groups (here, four groups).

  Here, what is called a group in this embodiment is a combination of a sensor (detection location) and a time zone, and a sensor selected for each combination of groups in the comparison step (FIG. 8: S26). And the monitoring data of the time zone are respectively compared with the comparison data. In addition, when it is determined that there is an abnormality in the abnormality determination step (FIG. 9: S27), the warning that is performed in the warning step (FIG. 9: S29) is also performed in this group unit.

  In FIG. 11, when the group selection (S601) is completed, the warning setting is changed for this group. In this description, it is assumed that the group 01 in which the name “wake up” is registered is selected. The purpose of this group is to detect whether or not the monitored person has woken up as scheduled and detect the abnormality of the monitored person.

  First, when changing the sensor 30 to be monitored (see FIG. 2) (S602: YES), a sensor change process for selecting an arbitrary sensor 30 by operating the mouse in the bedroom 86a, the living room 86b, the Japanese-style room 86c, and the kitchen 86d. Is executed (S603). Here, the bedroom 86a is selected for that purpose, and the other sensors are released.

  Subsequently, when changing the time zone (S604: YES), from the area 80 arranged in a keyboard shape for each time zone, an arbitrary time zone, here, an area displayed as "6, 7, 8", that is, , 6:00 am to 7:00 am (7 am is not included. The same applies to the following), and the time zone change process is executed by clicking the time zone between 7 o'clock and 8 o'clock with the mouse ( S605). Then, for example, the color of the area changes from white to black, and the time zone selected as the time to be monitored in this group can be grasped at a glance. To cancel the monitoring, if the mouse is clicked again, the color changes from black to white, and it can be clearly understood that the monitoring has been canceled.

  Subsequently, when the set range is changed (S606: YES), a display of “difference from average” and a text box 97 adjacent thereto are displayed at the bottom of the warning setting screen 73c. A setting range change process is performed in which the text box 97 is clicked to input a number (S607). This is a threshold value for determining how much the difference between the monitoring data and the comparison data is to give a warning.

  When it is desired to change the comparison data (S608: YES), a comparison data change process (S609) is executed. Here, FIG. 13 is a flowchart illustrating the comparison data change process (S609) in detail. The comparison data change process (S609) is performed by any one of the “1-month average” button 87a, the “6-month average” button 87b, and the “user setting” button 87c displayed at the bottom of the main screen 73a shown in FIG. First, it is determined whether the user setting is made by the operated button (S901). If the “user setting” button 87c is operated (S901: YES), the process proceeds to manual setting processing by the user. When shifting to the manual setting, as shown in the comparison data change screen 73e shown in FIG. 18, the comparison data input box 100 is displayed for each time zone, and each box displays the value of the currently set comparison data. ing. This comparison data input box 100 can be selected directly with a mouse 75 to input numbers.

  Here, in order to set the comparison data, the past detection history data may not be referred to (S902: NO), and direct comparison data may be input for each time zone (S908). There is a case where reference is desired (S902: YES). In this case, the “return” button 101 displayed on the upper part of the comparison data change screen 73e is operated. Then, since the main screen 73a shown in FIG. 15 is returned, the date for specifying the detection history to be referred to as the designated date 85 is input (S903). Then, monitoring data is generated from the detection history of the specified day and displayed in a graph (S904). In this state, the “user setting” button 87c is operated. Then, the screen shifts to the comparison data change screen 73e shown in FIG. 18, and if the “numerical value” button 89 is operated, the selected detection history (monitoring data) is displayed in the area 80. If the displayed monitoring data is greatly different as the comparison data, the data cannot be copied and used (S905: NO), so the comparison data is directly input for each time zone (S908).

  Here, when the displayed detection history (monitoring data) is set as comparison data as it is (S905: YES), data is input to the comparison data input box 100 by operating the “copy” button 102 (S906). ). If it is set as comparison data without modification (S907: NO), the comparison data change process is terminated (end). If a numerical value is input for correction (S907: YES), the comparison data is corrected and input for each time zone in the comparison data input box 100 (S908).

  Next, when past detection data is accumulated to some extent and past detection history can be used as comparison data, the data is used. Here, if the past average is already used by setting, it can be the average value for a certain period in the past, for example, one month, but once set, it may deviate from the actual value by the passage of the period. Conceivable. Therefore, when it is desired to update the monitoring data (S909: YES), the server 4 requests the detection history required by the “update” button 98 shown in FIG. 15, and the comparison data is obtained based on the detection history of the most recent one month. Update (S911). This process is the same as the process of S23, S10-13, S24, and S31.

  On the other hand, when it is desired to use the past detection history as it is (S909: NO), the “one month average” button 87a or the “six month average” button 87b is operated to select a period (S910). If the “average for one month” button 87a has been operated (S912: YES), the comparison data is read from the detection history of the most recent one month from the server 4, and the comparison data is set based on that data ( S913). Similarly, if the “6-month average” button 87b is operated (S912: NO), the comparison data is read out from the server 4 as the detection history of the most recent 6 months, and the comparison data is based on the data. Is set (S914). Thus, the comparison data change process (S609) ends (end).

  In the warning setting screen 73c, there is a case where it is desired to confirm whether or not the warning setting is finished and the warning is actually issued (S620: YES). In this case, when the “Check” button 99 is clicked, if there is a warning, a warning list screen 73d is displayed, and a group with a warning is colored in the list portion, and the graph blinks. ) Is executed to check whether the warning setting is appropriate or the current situation.

If it is not a group setting, that is, if it is a common setting (S600: NO), the setting is performed on the main screen 73a.
First, when the unit of the time zone is to be changed between 60 minutes and 15 minutes (S610: YES), the “60 minute unit / 15 minute unit” switching button displayed at the top of the main screen 73a shown in FIG. A time zone change process (S611) is executed by switching 94 with a mouse click.

  In addition, it is desirable to give appropriate names to the group name and sensor name so that the purpose and monitoring location can be intuitively understood. For example, as in the group 01 of this embodiment, the purpose is to check the monitored person's getting up every morning, so the group 01 is given the name “getting up” and the place where the monitored person goes to sleep. The sensor button 86 is named “bedroom”. If it is desired to change the name (S612: YES), clicking the “rename” button 93 displayed at the top of the main screen 73a (see FIG. 15) will omit the illustration, but the groups 01 to 04 and the sensor 01 will be omitted. Since a text box for changing the names of ~ 04 is displayed, the name change processing (S613) is executed by inputting the name here.

  In addition, in the main screen 73a and the warning setting screen 73c, when the monitoring data graph 81 and the comparison data graph 82 displayed as graphs are numerically displayed in the area 80 (S614: YES), the “numerical value” button 89 is clicked. Is displayed (S615).

  Also, in the main screen 73a and the warning setting screen 73c, when it is desired to display a warning setting list in order to check what warning setting each group currently has (S616: YES), the “Warning” By clicking the “list” button 96, a warning list screen 73d as shown in FIG. 17 is displayed (S617).

  The warning list screen 73d displays the warning setting contents set as the groups 01 to 04 in the same manner as the contents shown in FIG. Here, the name of each group, the name of the selected sensor, the selected time zone, and the warning difference that is the set difference are displayed in a list for each group. For this reason, various settings for one warning group can be understood at a glance, and comparison with other warning groups can be very easily performed.

  Further, in the main screen 73a shown in FIG. 15, there is a case where it is desired to change the numerical value display of the unit of the scale 83 so that the monitoring data graph 81 and the comparison data graph 82 can be easily seen (S618: YES). In this case, if an appropriate numerical value is input to the text box 84, the Y-axis unit change process (S619) in which the display scales of the monitoring data graph 81 and the comparative data graph 82 are automatically corrected including the intermediate scale according to the numerical value. ) Is executed.

This completes the group setting.
When one of the group setting processes is completed, or one of the common setting processes is completed, or when another warning setting change process is desired (S622: NO), S601 to S610 are also performed. The process is repeated, and if there is no process, the process ends (S622: YES, end).

  This completes the warning setting change process (S316) shown in FIG. Here, if there is no monitoring date specification change (S311), sensor specification change (S313), or warning setting change (S315) processing (S317: YES), the setting change processing (S31) shown in FIG.

This embodiment has the following effects because the above-described procedure is executed in the system configuration as described above.
(1) In this embodiment, since monitoring is performed based on the detection signal from the sensor 30, there is an effect that it is possible to always monitor the abnormality while respecting the privacy of the monitored person without relaying the video.

  (2) In addition, in order to determine the monitoring data of the monitored person based on the comparison data set in advance for each period of time created from the detection history of the monitored person, a determination according to the behavior pattern of the monitored person is performed. As a result, there is an effect that warning without leakage and noise can be performed.

  (3) Further, since the monitoring computer is constructed by the client server system and functions are shared, a large number of supervisor terminals 6 can be managed on the Internet 5 by the server 4. In particular, the software for managing warnings of the system 1 is a program (for example, FLASH) executed on the web browser (for example, Internet Explorer) of the supervisor terminal 6 and functions as an agent of the supervisor terminal 6. . This program is downloaded when the monitor terminal 6 accesses the server 4. Therefore, this program can always be kept up-to-date, and even if the number of supervisor terminals increases, the server 4 is hardly burdened with warning management. Therefore, the server 4 has an effect that it is easy to remotely monitor a large number of monitored persons over a wide area.

  (4) On the screen of the display 73 of the monitor terminal 6, the monitor data graph 81 that is the actual condition of the monitor person is displayed so as to be comparable with the comparison data graph 82 that is a criterion for abnormality determination. While making it easy to analyze the behavior pattern, it is possible to improve the accuracy of abnormality prediction by correcting the comparison data.

  (5) Also, if you want to monitor and warn by paying attention to the “wake-up” of the monitored person, specify the time and place where the monitored person gets up, and name the combination “wake-up” as a group. , You can intuitively understand what kind of warning it is. Since a plurality (in this case, four) groups are created and monitored according to the behavior pattern of the monitored person, there is an effect that the monitored person can be monitored in many ways.

  (6) Further, since the set difference that becomes the determination criterion for the abnormality determination can be set according to the behavior pattern of the monitored person (FIG. 11, S607), the importance and necessity more according to the behavior pattern of the monitored person There is an effect that it is possible to make an abnormality determination corresponding to.

  (7) Since the correction of the comparison data can be performed while referring to any detection history (monitoring data), the comparison data can be more suitable for the monitored person's behavior pattern, and the actual condition of the monitored person There is an effect that abnormality determination can be performed.

  (8) If past detection history is accumulated, comparison data can be automatically generated from the average. Then, although it is a simple procedure, the comparison data can be based on the past results, and can be assumed to be in the behavior pattern of the monitored person.

  (9) The warning according to the present embodiment displays the warning screen 73b on the screen of the supervisor terminal 6 and can also contact the supervisor's mobile phone by e-mail, and reliably monitors when an abnormality occurs. The person can be notified. In addition, as a warning means, the thing using the display screen, ringtone, etc. of the portable terminal may be used.

  (10) Since the warning means alerts the monitor by the display screen of the mobile phone or the sound generator, the monitor can monitor the monitored person as long as the mobile phone is carried. .

This embodiment can be implemented with the following modifications.
In this embodiment, an example of the configuration and procedure is described using a block diagram, a flowchart, etc., but the present invention is not limited to this block diagram, flowchart, etc., and the order of the configuration / procedure, addition Needless to say, deletion and replacement are appropriately performed by those skilled in the art.

  For example, in this embodiment, the supervisor terminal 6 performs the steps of comparison (S26), abnormality determination (S27), and warning (S29), but the server 4 may perform such processing. . For example, instead of a busy user, the server 4 has a function equivalent to that of the supervisor terminal 6, warns the supervisor terminal 6 of the supervisor when there is a warning, and alerts the mobile phone 8 by e-mail. To do. Of course, a configuration that can be omitted can be omitted.

  Although the supervisor terminal 6 is represented as a desktop type PC in FIG. 1, the supervisor terminal 6 itself may be configured by a mobile phone. By doing so, not only the reception of warnings but also various settings can be performed from any location on the mobile phone.

  The mobile phone 8 of this modified example is a well-known cellular mobile communication device as shown in FIG. 1, and is connected to the Internet 5 through the mobile phone network 7 and includes an Internet WWW browser. Combines client computer functions. The electronic mail transmitted from the safety remote monitoring server 4 having a mail server function can be received. In particular, in the present embodiment, a display screen including a high-definition moving image described in HTML, JAVA (registered trademark), FLASH, or the like in a predetermined format adapted to a mobile phone can be displayed. An example having a display capability equivalent to that of the apparatus will be described. Then, by accessing a predetermined URL, the target text, still image, moving image, voice, etc. can be obtained as hypertext from the target WWW server. Specifically, in the present modification example, a predetermined screen (for example, FIGS. 15 to 18 or a simplified diagram thereof) is displayed on the screen of the mobile phone 8 from the server 4.

  In this embodiment, the supervisor terminal 6 and the mobile phone 8 are described as typical terminals, but a micro-cellular mobile terminal (for example, a PHS (Personal Handyphone, registered trademark) equipped with a WWW browser) ) Etc. can also be used. The terminal may be a PDA (Personal Digital Assistant) or the like as long as it has a browser capable of receiving e-mail and browsing the web page of the Internet 5. Further, the type of car navigation system, home wired telephone on a general line, STB (Set Top Box), home game machine, etc. is not limited. Furthermore, it can be used for notifying the abnormality by voice or text by a pager such as a pager (registered trademark) without performing notification by e-mail. Alternatively, for information only, a telephone / facsimile phone call using synthesized voice or recorded voice may be automatically placed.

  In the present embodiment, the warning is set in units of one hour, but may be managed in units of 15 minutes, for example. Alternatively, it may be set for each day of the week. In this case, for example, by setting warnings separately from Monday to Friday and Saturday / Sunday, it is possible to perform warning settings that match the behavior pattern of the monitored person.

  In addition, in this embodiment, when the supervisor terminal 6 accesses the server 4, the detection history of the day before is extracted and judged / warned with the default value, but for example, at the stage when each time slot has ended The server 4 may be configured to automatically update the detection history. In addition, the comparison data is updated by the operation of the supervisor, but this may be automatically updated.

-This invention is not limited to the said embodiment and modification, It cannot be overemphasized that it is improved and changed by those skilled in the art, unless it deviates from a claim.
The technical idea disclosed in the present application will be added below.
