In addition, all or a part of the temperature sensor, the humidity sensor, the illuminance sensor, and the atmospheric pressure sensor can be used as the environment sensor 12, and a combination of some sensors can be used as the environment sensor 12.

The wireless communication unit 13 includes an antenna (not shown) that transmits a predetermined radio wave, and is a communication unit that enables wireless data communication with the mobile terminal 4 that is located within a certain reception intensity area (receivable area). It is.
Specifically, the wireless communication unit 13 is a wireless LAN (Wi-Fi: registered trademark) communication interface compatible with the IEEE 802.11 standard (referring to general wireless LAN standards including IEEE 802.11b / g and the like). is there.

The data transmitted by the wireless communication unit 13 includes a beacon including an SSID that can identify the monitor device 1.
Beacons are always distributed (transmitted) at a predetermined interval (for example, every 100 milliseconds). The beacon receivable area is a concentric area having a line-of-sight of about 100 m from the monitor device 1.
The data received by the wireless communication unit 13 is data transmitted from the mobile terminal 4 located in the beacon receivable area, and is registered data in the monitor device registration table t1 (see FIG. 5) or an alarm determination table. There is setting data of t3 (see FIG. 14).
Further, the data transmitted / received via the wireless communication unit 13 includes data that is previously transferred to each other when a communication line (data link) is established with the mobile terminal 4.
Such data includes at least a connection request received from the mobile terminal 4 and a connection response transmitted to the mobile terminal 4 in response to the connection request.

As shown in FIG. 1 and the like, the bed leaving information processing system according to the present embodiment includes a monitor device 1 and a mobile terminal 4 located in a beacon receivable area that is constantly transmitted from the monitor device 1. This network system does not necessarily require connection to an external network.

As shown in FIG. 4 (i), the SSID is composed of character string information (alphanumeric characters and predetermined symbols) of a maximum of 32 digits, and a preset character string can be changed to an arbitrary character string. It can be done.
The storage unit 15 of the present embodiment stores the SSID changed by the setting operation of the control unit 16 described later.
The data stored in the storage unit 15 includes monitor device registration table t1 (see FIG. 5), recorded information (see FIG. 11) that records the subject's bed leaving state and environmental information in association with time information, and alarm determination. There is a table t3 (see FIG. 14).

The control unit 16 is configured by a computer including a CPU, and performs a connection operation based on a connection process defined in the IEEE 802.11 standard, so that the control unit 16 can communicate with the portable terminal 4 of the same standard located in the beacon receiving area. Thus, data can be transmitted and received.
Specifically, based on the SSID designated by the mobile terminal 4, a predetermined connection request including its own SSID is received, and a connection response to the connection request is transmitted to the mobile terminal 4. Establish a data link.
When the data link is established, data can be transmitted and received between the monitor device 1 and the portable terminal 4 (see FIG. 10 (ii)).
For establishing a data link, an operation of receiving a probe request from the mobile terminal 4 that cannot receive a beacon and transmitting a probe response to the probe request to the mobile terminal 4 as an operation before the connection request and connection response described above. In some cases, the connection process includes an operation of transmitting and receiving authentication information and the like when performing predetermined authentication.

  Here, the monitor device 1 of the present embodiment enables bidirectional data communication with the mobile terminal 4 by the connection operation based on the connection process, but without such a connection process, the mobile terminal The data which can specify a test subject's bed leaving state to 4 is transmitted. Specifically, the control unit 16 performs the following operation.

Based on a predetermined operation, the control unit 16 operates as a first setting unit that sets first information corresponding to the number of digits in the first range among the number of digits of the SSID.
Moreover, the control part 16 sets the 2nd information corresponding to the number of digits of a 2nd range among the number of digits of SSID based on the fluctuation information which concerns on the bed leaving state detected by the predetermined | prescribed detection means. Works as.
By setting the first information and the second information by the first setting means and the second setting means, specifically, as shown in FIG. 4 (i), "facility specific information", "monitor device management number" , An “SSID” composed of “subject name” and “message part” is generated.
The “facility-specific information” is identification information that can identify the facility where the bed leaving information processing system is installed. The “monitor device management number” is identification information that can specify the monitor device 1, and for example, a room number or a bed number in which the monitor device 1 is installed can be used. The “subject name” corresponds to a name or the like that can identify the subject. The “message part” is composed of variation information including a subject's bed leaving state and environmental information.
Among these, the facility-specific information, the monitor management number, and the subject name are the first information of the present invention (see FIG. 4 (iii)), and these information can be set based on a predetermined operation.
It should be noted that the facility-specific information, the monitor management number, and all or part of the subject name can be used as the first information, and a combination of some information can be used as the first information.
Specifically, the monitor device registration table t1 (see FIG. 5) is registered based on the registration operation of the monitor device 1 by the operation of the portable terminal 4, and the first information is set based on the monitor device registration table t1. .

A registration method of the monitor device registration table t1 will be described with reference to FIGS. 8A and 8B.
Note that a predetermined application program (applied later) is installed in the mobile terminal 4, and a registration operation is performed according to a guidance screen displayed by the operation of this application. Further, it is assumed that the monitor device 1 having the management numbers 101 to 103 has already been registered, and the facility-specific information of the monitor device 1 to be registered has been registered.

First, the monitor device registration screen shown in FIG. 8A (i) is displayed on the display unit 43 by a predetermined operation on the portable terminal 4.
When the “Yes” button for continuing the registration of the monitor device 1 is selected on the monitor device registration screen, the home screen shown in FIG. 8A (ii) is displayed.
When the “Operation Confirmation & Setting” button is selected on the home screen, a setting screen shown in FIG. 8A (iii) is displayed.
When the “sensor registration / change” button is selected on the setting screen, a list display screen of the monitor device 1 shown in FIG. 8A (iv) is displayed. Note that the management number or the like is not displayed for the unregistered (registered) monitor device 1, and the SSID is displayed as it is.

When an unregistered monitor device 1 is selected, a password input screen shown in FIG. 8B (i) is displayed.
In the password input field, a predetermined password (for example, a password described in a guide bundled with the monitor device 1 or a two-dimensional code affixed to the monitor device 1 is automatically read by using the camera function of the mobile terminal 4. When the “connect” button is selected, the portable terminal 4 displays a screen prompting for input of a management number, name, and change password while connecting to the monitor device 1.
In response to the selection of the “Connect” button, a connection request is made from the mobile terminal 4 to the monitor device 1, and when the data link is established due to the connection response, the monitor device 1 receives the data from the mobile terminal 4. It becomes ready to receive.
Here, when the management number (104) and name (Watanabe) are input in accordance with the guidance on the screen and the “Setting” button is selected, these registration data are transmitted to the monitor device 1. Note that the password can be changed by inputting the changed password and selecting the setting button.
When receiving the registration data from the portable terminal 4, the monitor device 1 stores the monitor device registration table t1 in the storage unit 15 based on the registration data (see FIG. 5). In the portable terminal 4, a registration completion screen shown in FIG. 8B (iii) is displayed.
Thereby, the registration of the monitor device registration table t1 is completed.
In addition, when the subject is changed, the corresponding portion of the monitor device registration table t1 is changed by performing the same operation as described above.

  The control unit 16 refers to the monitor device registration table t1, and sets the facility-specific information, the monitor device management number, and the subject name in the first to 17th digits (the number of digits in the first range) as the corresponding first information. . Specifically, facility specific information (such as “SS-200”) is set in the first to sixth digits, and a monitor device management number (such as “104”) is set in the seventh to ninth digits. A subject name (such as “12345678”) is set in the 10th to 17th digits (see FIGS. 4 (i) and (iii)). The subject name information is the code information of the Kanji character “Watanabe”, and the kanji name registered in the monitor device registration table t1 is automatically coded and set based on, for example, JIS, UTF-8, etc. can do.

As shown in FIG. 4 (ii), in the “message part”, information that can identify the subject's bed leaving state such as falling asleep, getting up, getting up, getting out of bed (leaving state information), temperature, humidity, illuminance, barometric pressure, etc. Fluctuation information such as the environmental information around the subject, the time such as the bed entry time and the bed leaving time, and an alarm notification flag used for alarm notification are set.
Among these, the bed leaving state information corresponds to the second information of the present invention, and is set to the 18th to 19th digits (the number of digits in the second range). For example, “00” indicates falling asleep, “01” indicates “awake”, “01” indicates “awake (wake)”, and “11”.
In addition, you can use all or part of the sleep, enter, get up, get out, temperature, humidity, illuminance, barometric pressure, enter time, get out time, and alarm notification flag as setting information in the message part. Can be used as the setting information of the message part.

As the second information, for example, when the bed leaving state determined by the bed leaving determination unit described later is changed, the changed bed leaving state information can be set.
The bed leaving determination unit is a unit that determines the bed leaving state of the subject. Specifically, the control unit 16 can make a determination based on the biological signal (biological information) input by the biological signal input unit 11.
For example, it can be determined that the user “gets out of bed” when the biological signal is not detected (input), and “bed” when the biological signal is detected (input).
And the control part 16 can detect that the bed leaving state changed based on the bed leaving state determined by the bed leaving determining unit by operating as the bed leaving detecting unit.
For example, when the bed leaving state changes from “getting out of bed” to “being in bed”, it can be determined as “bed in”. In this case, the bed leaving state information indicating “bed in” corresponds to the second information.
In addition, “sleeping” and “wakefulness (wake-up)” can be detected based on characteristic changes in the biological signal detected while in bed. In this case, “sleeping” and “wake-up (wake-up)” The bed leaving state information shown corresponds to second information, respectively.
Note that the second information can be set based on a predetermined time or a fixed interval, not the timing at which the bed leaving state changes.
The environmental information can be set to the 20th to 22nd digits, for example, and the input value of the environmental sensor 12 can be set as it is.
The setting of the environment information can be performed at the same timing as the setting of the second information or at an individually set timing. For example, it can be set when the change of the input value exceeds a predetermined threshold, or based on a predetermined time or a fixed interval.

FIG. 4 (iii) is an example of the SSID generated by setting the first information, the second information, and the environment information.
The generated SSID is stored in a predetermined area of the storage unit 15, and is overwritten and changed (updated) every time the SSID is set.
For this reason, the number of digits in the first range in the SSID is changed when the first information is set, and is then fixed unless changed.
Of the SSID, the number of digits in the second range is changed to second information every time the bed leaving state changes.

When the wireless communication unit 13 transmits a beacon, the control unit 16 performs an operation of taking out the SSID in which the first information and the second information are set from the storage unit 15 and transmitting the SSID in the beacon to the surroundings.
Thereby, the portable terminal 4 located in the receivable area receives the beacon, and can determine the management number of the monitor device 1, the subject name, and the subject's bed leaving state from the SSID included in the beacon. Environmental information can be acquired.

(Mobile device)
The portable terminal 4 is a communication terminal device of the present invention, and corresponds to a portable communication terminal device such as a smartphone or a tablet, for example.
As illustrated in FIG. 6, the mobile terminal 4 includes a wireless communication unit 41, a storage unit 42, a display unit 43, and a control unit 44.
The wireless communication unit 41 is a wireless LAN communication interface compatible with the IEEE 802.11 standard, and performs a connection operation based on a predetermined connection process with the monitor device 1 having the communication LAN interface of the standard. Data can be sent and received.
Data received by the wireless communication unit 41 includes a beacon transmitted from the monitor device 1. That is, the wireless communication unit 41 operates as a receiving unit that receives the SSID included in the beacon.
Data transmitted from the wireless communication unit 41 includes registration data (see FIG. 5) in the monitor device registration table t1 and setting data in the alarm determination table t3 (see FIG. 14).
In addition, the data transmitted and received via the wireless communication unit 41 includes data that is previously passed between each other when a data link is established with the monitor device 1.
Such data includes a connection request transmitted to the monitor device 1 and a connection response received from the monitor device 1 in response to this connection request.

The storage unit 42 includes, for example, a RAM constituting the control unit 44, a non-volatile memory such as an EEPROM or a flash memory connected by the control unit 44, and a program for executing various functions provided in the portable terminal 4 And memorize data.
The program stored in the storage unit 42 is a program corresponding to the bed leaving information processing program of the present invention, and an application program for displaying the bed leaving state of the subject based on the SSID transmitted from the monitor device 1 ( (Hereinafter referred to as an app).
The application can be downloaded from a predetermined website or installed from an external storage medium such as a USB memory.
The data stored in the storage unit 42 includes a state identification table t2 in which the bed leaving state information and the icon identification information are associated with each other. The state identification table t2 is included in the application in advance, and is stored in the storage unit 42 by installing the application.

The display part 43 consists of a liquid crystal display, an organic EL display, etc., and can display a test subject's bed leaving state, sleep state, and environmental information.
The display unit 43 includes a touch panel that can be touch-operated, and accepts settings by touching the screen with a finger or a touch pen on various setting screens.

The control unit 44 is configured by a computer including a CPU, and executes various functions included in the portable terminal 4 by executing a program stored in the storage unit 42.
For example, a data link capable of bidirectional data communication with the monitor device 1 can be established by performing a predetermined connection operation.

The control unit 44 causes the display unit 43 serving as a display unit to perform an operation of displaying information that can identify the bed leaving state based on the SSID received by the receiving unit.
Specifically, in the SSID, for the 18th to 19th digits for which the bed leaving state information is set, the control unit 44 specifies corresponding icon identification information with reference to the state identification table t2. For example, when the SSID in which the information shown in FIG. 4 (iii) is set is received, the 18th to 19th digits of the SSID are “11”. "Icon d" indicating "can be specified.
About the 10th digit-the 17th digit in which the code information of a test subject name is set, the control part 44 can specify a Chinese character name by decoding. Accordingly, the subject name “Watanabe” can be specified from “12345678” in the 10th to 17th digits.
In addition, among the predetermined number of digits of the SSID, the first to sixth digits are facility specific information, the seventh to ninth digits are monitor device management numbers, and the 20th to 22nd digits are temperature information. The information 44 is handled as it is.

Therefore, from the SSID shown in FIG. 4 (iii), the facility-specific information “SS-200”, the monitor device management number “101”, the subject name “Watanabe”, the leaving state “wake (wake up)”, the icon identification information “icon” d ”and temperature“ 20 ° C. ”can be extracted.
Thereby, in the portable terminal 4, based on these extracted information, a bed leaving state etc. of each test subject can be displayed.
Specifically, as shown in FIG. 9, the management number of the monitor device 1, the subject name, and the bed leaving state icon are associated with each other, and this association can be displayed as a list for each monitor device 1.
For example, from FIG. 9, the subject “Maeda-sama” with the management number “101” can grasp that he / she is getting up (being in bed) by looking at the getting-off state icon, and similarly, the management number “102”. It is possible to grasp that the subject “Suzuki-sama” is sleeping and the subject “Satoshi Watanabe” with the management number “104” is getting out of bed. In addition, based on the intensity of received radio waves such as a beacon, an icon that can identify the radio field intensity can be displayed in association with each other (see FIG. 9).
For this reason, when the bed leaving information processing system of the present embodiment is introduced into a facility such as a nursing home, for example, it is possible to grasp the bed leaving condition and environment of the subject anywhere within the facility as long as it is within the beacon reception area. Can do.

Moreover, in the bed leaving information processing system of this embodiment, by accessing the monitor device 1 from the portable terminal 4, it is possible to acquire past records about the bed leaving state and environmental information of the subject and display them in a viewable manner. .
For this reason, in the monitor apparatus 1, as shown in FIG. 11, record information in which the bed leaving state and the environment information are associated with the time information for each management number and subject is stored in the storage unit 15.
For example, the sleep state of the subject can be displayed in a graph according to a request from the mobile terminal 4.
For example, when the “sleep recording” button is selected on the screen shown in FIG. 8A (ii), the list display screen shown in FIG. 8A (iv) is displayed, and the management number is selected from the monitor devices 1 displayed on this list display screen. By selecting the monitor device 1 of “101”, the sleep state graph screen shown in FIG. 12 can be displayed.
In the sleep state graph, a graph and sleep time of each day's sleep state (sleeping and awakening) over the past week for each specific monitor device and subject are displayed. For this reason, a subject's past sleep tendency can be grasped easily.
It is also possible to display the presence or absence of the subject's current body motion signal.

By the way, data of a size that does not fit in the SSID data frame, such as recording for a certain period of time in the past, is transmitted from the monitor device 1 to the mobile terminal 4 or from the mobile terminal 4 to the monitor device 1 such as the monitor device registration table t1. When transmitting data, it is necessary to establish a data link between the portable terminal 4 and the monitor device 1.
In this regard, when the SSID is changed and used as in the bed leaving information processing system of the present embodiment, the connection request destination cannot be specified from the mobile terminal 4 and a data link is established with the desired monitor device 1. I can't.
For this reason, in a predetermined case, a mode for fixing the SSID (fixed mode) can be set, and the SSID can be prevented from changing while the fixed mode is set.
For example, when browsing a sleep state graph, a predetermined connection operation can be performed by setting a fixed mode in advance and designating a fixed SSID.

Thus, the bed information processing system according to the present embodiment includes the monitor device 1 that is electrically connected to the airbag sensor 2 that detects the body movement of the subject, and information transmitted from the monitor device 1. The monitor device 1 is within the beacon receivable area by generating an SSID based on the bed leaving state information and transmitting it to the surroundings by including it in the beacon. The portable terminal 4 is configured to check the subject's bed leaving state based on the SSID.
Such a bed leaving information processing system according to the present embodiment is configured by a monitor device 1 and a mobile terminal 4 that is located in a beacon receivable area that is constantly transmitted from the monitor device 1 to the surroundings. Can be easily introduced.
Further, for example, when the bed leaving information processing system of the present embodiment is introduced into a facility such as a nursing home, when the monitor device 1 is installed so that the beacon receivable area covers the entire facility, the administrator or the like Wherever you are in the facility, you can check the subject's bed leaving condition, etc. via the portable terminal 4 that you carry with you.

In addition, while omitting the connection process between the base unit and the handset of the wireless LAN, pay attention to the beacon that is constantly transmitted from the base unit to the surroundings, and include the information about getting out of bed in the SSID included in this beacon. This makes it possible to quickly and stably get out of bed information.
The characteristics of such a bed leaving information processing system will be described with reference to FIG.
FIG. 10 (i) is a sequence diagram showing the operation in the information processing system for getting out of the bed according to the present embodiment, and FIG. 10 (ii) shows the operation of the wireless LAN normally performed between the monitor device and the portable terminal. It is a sequence diagram.
As shown in FIG. 10 (i), in the bed information processing system of the present embodiment, the mobile terminal 4 receives a beacon that is constantly transmitted from the monitor device 1, and receives predetermined information based on the SSID included in this beacon. It is trying to display.
On the other hand, in the normal wireless LAN operation shown in FIG. 10 (ii), in addition to beacon transmission, a connection request made from the mobile terminal 4 to the monitor device 1, and from the monitor device 1 to the mobile terminal 4 The mobile terminal 4 can receive necessary information from the monitor device 1 after the connection response is performed and the data link is established through such a connection process.
In addition, as a connection process (not shown), as an operation before the connection request and the connection response, an operation of receiving a probe request from the mobile terminal 4 that cannot receive a beacon and transmitting a probe response to the probe request to the mobile terminal 4; In some cases, the authentication information and the like are transmitted and received when the authentication is performed.

That is, according to the information processing system of the present embodiment, the normal connection process in the wireless LAN is not performed, and the SSID configured by necessary information is included in the beacon to perform one-way communication (only transmission). Therefore, information can be exchanged quickly.
In addition, as shown in FIG. 10 (ii), in the case of the method of performing data communication through the data link, when the radio wave reception intensity is low or unstable, the data link is disconnected and the reconnection operation associated therewith occurs. There is a problem that data cannot be exchanged or delayed.
On the other hand, in the bed leaving information processing system according to the present embodiment, the mobile terminal 4 only needs to receive the SSID included in the beacon. Therefore, even if the reception strength is low or unstable, the SSID is surely obtained. Can be handed over to.

(Alarm processing based on bed leaving time)
Next, alarm processing in the bed information processing system will be described.
The alarm process is a process for outputting an alarm by the portable terminal 4 when the test subject's bed is detected and the bed leaving time exceeds a predetermined time.
In the monitor device 1 that enables this alarm processing, the control unit 16 operates as a bed leaving detection unit, thereby performing an operation of detecting that the subject has left the bed based on the biological information. The subject's getting out of bed can be detected, for example, when the getting-off state changes from “being in bed” or “awakening (wake-up)” to “getting out of bed” based on the determination by the bed leaving determining means.

In addition, the control unit 16 operates as an alarm determination unit, so that, when bed leaving is detected, whether the bed leaving time detected by continuously leaving the bed exceeds a predetermined time corresponding to the time when the bed leaving is detected. Determine whether or not.
Specifically, in the monitor device 1, a timer value is registered in advance, and when bed leaving is detected, it is determined whether or not the bed leaving time exceeds the timer value.

The timer value can be registered by the following procedure based on the operation of the mobile terminal 4.
For example, the target monitor device 1 is selected from the monitor devices 1 displayed on the list display screen (FIG. 9), thereby causing the display unit 43 to display the operation mode setting screen shown in FIG. .
On the operation mode setting screen, every time the “Setting” button is pressed, the timer value is “5 minutes” → “10 minutes” → “30 minutes” → “60 minutes” → “detailed mode” → “1 minute” → When the “operation” button is selected after selecting a desired timer value, setting data including the timer value is transmitted to the target monitor device 1.

Further, by selecting the “detail mode setting” button on the operation mode setting screen, a detailed mode setting screen (basic) shown in FIG. 13 (ii) is displayed.
On the detailed mode setting screen (basic setting), an arbitrary timer value can be input.
When the timer value is input and the “setting” button is selected, the setting data is transmitted to the target monitor device 1.

When receiving the setting data from the mobile terminal 4, the monitor device 1 stores and registers the timer value included in the setting data in the storage unit 15.
Here, in the monitor device 1, when the subject's bed is detected, the control unit 16 causes the time measuring means to start measuring the time to measure the bed leaving time.
The control unit 16 determines whether or not the bed leaving time exceeds the timer value.

And the control part 16 transmits the notification information which makes predetermined | prescribed warning information output by the portable terminal 4 so that reception is possible by the portable terminal 4, when a bed leaving time exceeds a timer value.
Specifically, as the third information corresponding to the number of digits in the third range (for example, the 23rd digit) among the predetermined number of digits of the SSID, the control unit 16 operates as the third information setting unit, and the alarm A notification flag (see FIG. 4 (ii)) is set, and a beacon including the set SSID is transmitted.
Thereby, based on the SSID included in the beacon received by the mobile terminal 4, a predetermined alarm can be output based on the alarm notification flag set to the predetermined number of digits (23rd digit) of the SSID. .

Furthermore, in the bed leaving information processing system of this embodiment, when the bed leaving time exceeds a predetermined time corresponding to the time when bed leaving is detected, an alarm can be output from the mobile terminal 4.
Therefore, the alarm determination table t3 in which the target time and the timer value are associated in advance is registered in the monitor device 1.
The alarm determination table t3 can be registered according to the following procedure based on the operation of the portable terminal 4.

First, by selecting the “individual 1” button displayed on the detailed mode setting screen (basic) shown in FIG. 13 (ii), the “detailed mode setting screen (individual)” shown in FIG. 13 (iii) is displayed. Let
On the detailed mode setting screen (individual), an arbitrary timer value can be input together with a desired time zone.
For example, as shown in FIG. 13 (iii), “14: 0 to 16:00” can be input as the time zone, and “100 minutes” can be input as the timer value.
When a time zone and a timer value are input and a setting button is selected, setting data including the time zone and the timer value is transmitted to the target monitor device 1.
A plurality of setting data such as individual 2 and individual 3 can be input and transmitted.

When the monitor device 1 receives the setting data from the portable terminal 4, the monitoring device 1 extracts the association data of the time zone and the timer value from the setting data, and stores them in the storage unit 15 as the alarm determination table t3. Thereby, the alarm determination table t3 shown in FIG. 14 is registered.
When the monitor device 1 detects bed removal, an alarm determination operation is performed based on the alarm determination table t3.
Here, the alarm determination operation will be described with reference to the flowchart shown in FIG.

As shown in FIG. 15, the monitor device 1 monitors the detection of getting out of bed (S21). Specifically, “getting out of bed” is detected when the state of getting out of bed changes from “being in bed” or “wake-up (wake-up)” to “get-off”.
When getting out of bed is detected, the time of getting out of bed is acquired (S22), and the time measuring unit 14 starts measuring the time of getting off (time keeping) (S23).
Then, it is determined whether or not the bed leaving time exceeds the time corresponding to the bed detection time (S24).

In the alarm determination table t3 illustrated in FIG. 14, “individual 1” is set with “target time: 14: 00 to 16:00” and “timer value: 100 minutes”, and “individual 2” has “target “Time: 07: 00 to 22:00” and “Timer value: 60 minutes” are set, and “Individual 3” includes “Target time: 22: 01 to 06: 59” and “Timer value: 0 minute”. Is set.
For this reason, for example, when the bed leaving detection time is 15:00, the individual timer value is referred to. In this case, when the bed leaving time exceeds 100 minutes (S24-YES), the alarm notification flag is set to the predetermined number of digits of the SSID. To be included in the beacon and transmitted (S25).
Also, when the bed leaving detection time is 23:00, the individual timer value 3 is referred to. In this case, when the bed leaving time exceeds 0 minute (S24-YES), that is, immediately after the bed leaving detection, the alarm notification flag is set. The SSID is set to a predetermined number of digits and is included in the beacon and transmitted (S25).
In addition, although bed removal was detected, but bed removal time did not exceed the time corresponding to bed removal detection time (S24-NO), S25 is skipped and it returns to the process from S21.

If it does in this way, in the portable terminal 4 which received the beacon, a predetermined | prescribed screen display and a sound can be output based on the warning notification flag contained in a beacon.
Here, the beacon is continuously transmitted from the monitor device 1 to the surroundings.
For this reason, for example, in a facility such as a nursing home, if the beacon reception area covers the entire facility, the administrator or the like promptly alerts through the portable terminal 4 carried by him / her wherever he / she is in the facility. You can be notified.

In addition, since the beacon receivable area covers a range of 100 m in sight, the monitor device 1 can be installed so that the area extends to a peripheral area outside the facility such as a road around the facility.
In this way, for example, in a taxi company or a bus company that operates vehicles that regularly or irregularly pass through the roads around the facility, when the vehicle passes through the roads around the facility, the driver of the vehicle An alarm can be notified to the portable terminal 4 carried.
For this reason, the service which can monitor a test subject from the outside of a facility can also be provided without using an external network.

In the alarm determination, the bed leaving time serving as a reference for the determination is set to a length corresponding to the bed leaving time (short at night and long during the day) for the following reason.
That is, in general, the test subject has a long wake-up time, and therefore, if the bed leaving time is shortened, there is a possibility that the test subject erroneously determines that normal behavior should be warned. On the other hand, it is normal for the subject to be in bed at night, and when bed leaving is detected at night, particularly when the subject is elderly, there is a possibility of hemorrhoids. In addition, because the surroundings are dark at night, discovery becomes more difficult as the initial actions such as searching for the bag are slower.
For this reason, the bed leaving time, which is a criterion for alarm determination, is shortened at night and longer during the day, so that it is possible to accurately detect wrinkles and to quickly respond to wrinkles at night.

(Encryption of SSID configuration information)
Next, encryption of SSID configuration information will be described.
The SSID of the monitor device 1 is received by the mobile terminal 4 located in the area where beacons emitted from the monitor device 1 can be received, but this SSID is another unspecified wireless LAN slave device in the same area. Can be easily browsed.
In this regard, the SSID of this embodiment is problematic because it includes data relating to privacy such as the subject name.

For this reason, the bed information processing system of this embodiment can add a configuration in which the monitor device 1 encrypts the SSID configuration information and the mobile terminal 4 decrypts the SSID configuration information.
Specifically, in the monitor device 1, the control unit 16 operates as an encryption unit, thereby encrypting the subject name, bed leaving state information, etc., generating an SSID based on the encrypted information, and using this as a beacon. Including and sending.
In the mobile terminal 4, the control unit 44 operates as a decoding unit to perform a decoding process on the SSID included in the received beacon, thereby restoring information that can identify the bed leaving state and the like.
If it does in this way, it will become possible to prevent interception of the configuration information of SSID, and secrecy can be improved.

In the encryption / decryption process, a password, a manufacturing number unique to the monitor device 1, a MAC address, or the like can be used as a common key.
For example, by using a common password for facilities as a common key, key setting can be facilitated and operations such as password management can be simplified.
In this case, if the password is known to a third party, information on all the subjects residing in the facility is decrypted, and there is a risk that damage due to leakage will be serious.
For such a problem, damage can be minimized by using product-specific information such as a password, serial number, and MAC address provided for each monitor device 1 as a common key.

In this case, when the product unique information is used as the common key, the product unique information can be encrypted and included in the SSID, and part of the information other than the product unique information can be included in the SSID without being encrypted.
When the management number and manufacturing number of the monitor device 1 are included in the SSID, the management number is not encrypted, and other configuration information including the manufacturing number used as a common key is encrypted, and these non-encrypted information and encrypted Information is set as the SSID.
In this way, the third party can intercept the management number of the monitoring device 1 from the SSID included in the beacon, but the management number is not a problem because it is not information that is disadvantageous to the subject. Since the serial number and subject name, which are common keys, are encrypted, they cannot be intercepted.
In this case, the portable terminal 4 stores in advance table data in which the management number and the manufacturing number of the monitor device 1 are associated with each other.
When a beacon is received, the corresponding production number is extracted from the table data using the non-encrypted management number included in the SSID as a search key, and the entire SSID can be automatically decrypted using this production number as a decryption key.
According to such encryption / decryption processing, it is possible to provide a bed leaving information processing system that is safer and more convenient.

(Aspect as information processing device)
The bed information processing apparatus, the bed removal information processing system, and the bed removal information processing program that can identify the bed leaving state of the subject based on the biological information related to the bed leaving state have been mainly described above. It is also possible to function as an information processing apparatus that sets an SSID based on various pieces of fluctuation information detected by various methods and transmits the information by including it in a beacon.
Specifically, specific information corresponding to the number of digits in a specific range out of a predetermined number of digits of the SSID based on variation information detected by a detection unit such as a sensor by the control unit 16 operating as a setting unit. Set.
Then, the control unit 16 causes the wireless communication unit 13 as a transmission unit to transmit the SSID in which the specific information is set included in the beacon.
Thereby, the portable terminal 4 in the beacon receivable area can receive the SSID via the beacon, and can specify the variation information based on the specific information constituting the SSID.

As the fluctuation information, water level information detected by a water level sensor, movement information of a person or an object detected by an optical sensor, loudness or frequency of sound detected by a sound sensor, and the like are assumed.
Among these, the case where the water level sensor provided in the breakwater of a coast is connected with the monitor apparatus 1 installed in the residential area near a coast is demonstrated, for example.
In this case, the water level information from the water level sensor is input to the monitoring device 1 regularly or irregularly, and the monitoring device 1 identifies the changed water level information when the input water level information changes beyond a predetermined threshold. As information, the number of digits in a specific range of the SSID (for example, the first digit to the third digit) is set.
Then, the monitoring device 1 includes the SSID constituted by the water level information in a beacon and transmits it to the surroundings.
If it does in this way, the inhabitant in the reception area of a beacon can know water level information immediately via the portable terminal 4 which he carries.
For this reason, it becomes possible to respond promptly and appropriately to disasters caused by tsunamis, typhoons and other large waves.

As described above, according to the bed leaving information processing apparatus, the information processing apparatus, the bed leaving information processing system and the bed leaving information processing program according to the present embodiment, the bed leaving state and the like of the subject can be displayed on a network such as the Internet. It is not necessary and can be grasped via the portable terminal 4 by using the wireless LAN.
In addition, since the SSID generated based on the bed leaving information is included in the beacon without performing a predetermined connection process between the wireless LAN parent device and the child device, data communication is performed quickly. Can be performed.

On the other hand, in the conventional bed leaving information processing apparatus, when transmitting the bed leaving information of a subject to a portable terminal using a wireless LAN, a connection operation based on a predetermined connection process is performed, and a data link established by the connection operation is performed. Sending out bed information to the mobile terminal.
That is, it is necessary to go through a connection process before transferring data, and this is a factor that hinders rapid processing.
In addition, for areas with low radio field strength or unstable areas, getting out information cannot be delivered stably, and the connection process is repeated to establish a data link, thus hindering more rapid processing. It was.
In particular, when passing away bed information for a plurality of subjects to a portable terminal, a plurality of the above processes are performed in parallel, so the above problem becomes more apparent.

  According to the bed leaving information processing apparatus, the information processing apparatus, the bed leaving information processing system, and the bed leaving information processing program of the present embodiment, all or a part of such problems to be improved by the conventional bed leaving information processing apparatus are solved.

It goes without saying that the processing system and the bed leaving information processing program are not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention.
For example, regarding the setting of the SSID, the second information can be set in the portion including the first number of digits of the predetermined number of digits, and the first information can be set in the subsequent number of digits.
That is, the information to be set including the first information and the second information can be set in an arbitrary number of digits.

Moreover, the bed leaving information processing system of the present invention can be communicably connected to an external network such as the Internet via a wireless LAN router as shown in FIG.
Furthermore, by setting the monitor device 1 to the router mode, it is possible to connect to an external network regardless of the wireless LAN router.
As a result, it becomes possible to access the monitor device 1 from the external server device 5, and it is possible to receive (download) a record of getting out of the bed and environmental information from each monitor device 1 and display the list.

For example, the centralized monitor screen shown in FIG. 17 can be displayed on the server device.
On the centralized monitor screen, for each subject in the facility, the current biological information (heart rate, respiratory rate, presence / absence of body movement), bed leaving status (bed information, sleeping status, bed leaving status icon), environment ( Room temperature and humidity) can be displayed in a list for each subject name. The number of alarm notifications can also be displayed.

Moreover, in the server apparatus 5, the sleep graph display screen shown in FIG. 18 can be displayed.
The sleep graph display screen displays the sleep state of the subject subject in the target period (for example, the past month) as a graph, and shows whether it is bedtime, bedtime, wakeup time, bedtime, sleeping or awake. It is displayed so that it can be understood at a glance.
In this way, for example, even when not in the facility, the state of the subject can be grasped and analyzed in real time from a remote location.

In addition, various data stored in the monitor device 1 can be acquired via the server device 5 or the portable terminal 4.
For example, by storing the PDF data of the pamphlet shown in FIGS. 19A to 19C in the storage unit 15 of the monitor device 1, it can be downloaded to the server device 5 or the portable terminal 4 and displayed in a viewable manner. Can do.
