  Here, the monitoring device 1 according to the present embodiment can perform two-way data communication with the portable terminal 4 by the connection operation based on the above connection process, but without passing through such a connection process. It is made to transmit the data which can specify a test subject's leaving state to 4. Specifically, the control unit 16 performs the following operation.

The control unit 16 operates as a first setting unit configured to set first information corresponding to the number of digits of the first range among the number of digits of the SSID based on a predetermined operation.
In addition, the control unit 16 is a second setting unit configured to set second information corresponding to the number of digits of the second range among the number of digits of the SSID based on the variation information related to the floor state detected by the predetermined detection unit. Act as.
Specifically, by setting the first information and the second information by the first setting means and the second setting means, as shown in FIG. 4 (i), “facility specific information”, “monitoring device management number” , “Subject name”, and “message part” are generated.
The “facility specific information” is identification information that can identify the facility where the bed departure information processing system is installed.

The "message unit" is composed of fluctuation information including the patient's 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 (refer to FIG. 4 (iii)), and these information can be set based on a predetermined operation.
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 method of registering the monitor registration table t1 will be described with reference to FIGS. 8A and 8B.
A predetermined application program (application described later) is installed in the portable terminal 4, and the registration operation is performed according to the guidance screen displayed by the operation of the application. Further, it is assumed that the monitor devices 1 of management numbers 101 to 103 have already been registered, and the facility specific information of the monitor device 1 to be registered is 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 mobile 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 check & 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. In addition, about the monitor apparatus 1 of unregistered (registration object), a management number etc. are not displayed but SSID is displayed as it is.

When the 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, the password described in the guidance bundled with the monitor 1 or the two-dimensional code attached to the monitor 1 is read by the camera function of the portable terminal 4 When the user inputs a password) and selects the “connect” button, the mobile terminal 4 displays a screen prompting the user to input a management number, a name, and a change password while connecting with the monitor device 1.
When the connection request is issued from the portable terminal 4 to the monitor device 1 in response to the selection of the “connect” button, and the data link is established by the connection response, the monitor device 1 receives the data from the portable terminal 4. It becomes ready to receive.
Here, following the guidance of the screen, the management number (104) and the name (Watanabe) are input, and when the “setting” button is selected, these registration data are transmitted to the monitor device 1. When changing the password, it is possible to change the password 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). On the mobile terminal 4, a registration completion screen shown in FIG. 8B (iii) is displayed.
Thereby, registration of the monitoring device registration table t1 is completed.
In addition, when a test subject has a change etc., the corresponding location of the monitor apparatus registration table t1 is changed by performing operation similar to the above.

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

As shown in FIG. 4 (ii), the “message section” includes information (set-off state information) that can specify the test subject's leaving state such as sleeping, getting in, getting up, and leaving, temperature, humidity, illuminance, barometric pressure, etc. It sets fluctuation information such as time information such as environmental information around the subject, time of arrival and arrival, time of departure, and alarm notification flag used at the time of alarm notification.
Among these, the bed leaving state information corresponds to the second information of the present invention, and is set to the eighteenth to nineteenth digits (the number of digits in the second range). For example, "00" indicates sleep onset, "01" indicates "arrival", "01" indicates "wake up", and "11".
In addition, all or part of sleepiness, bedtime, bedtime, wakeup, bedtime, temperature, humidity, illuminance, barometric pressure, bedtime, bedtime, alarm notification flag can be used as setting information of the message section, and part A combination of the above information can be used as setting information of the message part.

As the second information, for example, when the bed leaving state determined by the bed leaving determining means changes, it is possible to set the changed bed leaving state information.
The bed leaving determination means is means for determining the bed leaving state of the subject, and specifically, the control unit 16 can make the determination based on the biological signal (biological information) input by the biological signal input unit 11.
For example, it can be determined that “bed up” is detected when a biological signal is not detected (input), and “present” is detected when a biological signal is detected (input).
And the control part 16 can detect that the bed separation state changed based on the bed separation state determined by the bed separation determination means by operate | moving as a bed separation detection means.
For example, it can be determined that "bed entering" is when the bed leaving state changes from "bed up" to "been on bed". In this case, the bed leaving state information indicating "bed entering" corresponds to the second information.
Moreover, based on the characteristic change of the biological signal detected during the bed, "sleeping" or "wakening (wake up)" can be detected, in this case, "sleeping", "wake up (wake up)" The bed leaving state information shown each corresponds to the second information.
The setting of the second information can also be made based on a predetermined time or a fixed interval, not the timing at which the bed leaving state changes.
The environment information can be set to, for example, the 20th to 22nd digits, and the input value of the environment 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 a separately set timing. For example, it can be set based on a change in input value exceeding a predetermined threshold or based on a predetermined time or a predetermined 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) each time the SSID is set.
For this reason, the number-of-digits portion in the first range of the SSID is changed when the first information is set, and thereafter fixed unless there is a change.
The number-of-digits part of the second range of the SSID is changed to the second information each time the floor state changes.

When the wireless communication unit 13 transmits a beacon, the control unit 16 takes out the SSID in which the first information and the second information are set from the storage unit 15, and performs an operation of including this in the beacon and transmitting it to the surroundings.
As a result, the portable terminal 4 located in the receivable area receives the beacon, and from the SSID included in the beacon, can identify the management number of the monitoring device 1, the subject name, and the floor state of the subject. , Environmental information etc. can be acquired.

(Mobile terminal)
The portable terminal 4 is the communication terminal device of the present invention, and corresponds to, for example, a portable communication terminal device such as a smartphone or a tablet.
As illustrated in FIG. 6, the portable 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 communication interface of a wireless LAN compliant 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. It enables transmission and reception of data.
The data received by the wireless communication unit 41 includes a beacon transmitted from the monitoring 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 include registration data (see FIG. 5) of the monitoring device registration table t1 and setting data of the alarm determination table t3 (see FIG. 14).
Further, data transmitted and received via the wireless communication unit 41 include data mutually transferred in advance when establishing a data link with the monitor device 1.
As such data, there are a connection request to be transmitted to the monitoring device 1 and a connection response to be received from the monitoring device 1 in response to the connection request.

The storage unit 42 is constituted by, for example, a RAM constituting the control unit 44, a non-volatile memory such as an EEPROM connected by the control unit 44, a flash memory or the like, and a program for executing various functions of the mobile terminal 4 And store 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 is an application program for displaying the subject's bed leaving state and the like based on the SSID transmitted from the monitor device 1 The following is called an application.
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 leaving state information and the icon identification information are associated with each other. The state identification table t2 is included in advance in the application, and is stored in the storage unit 42 by installing the application.

The display unit 43 includes a liquid crystal display, an organic EL display, and the like, and can display the subject's leaving state, sleeping state, and environmental information.
The display unit 43 is formed of a touch panel that can be touch-operated, and receives settings on the various setting screens and the like by touching the screen with a finger or a touch pen.

The control unit 44 is configured by a computer including a CPU, and executes the programs stored in the storage unit 42 to execute various functions of the portable terminal 4.
For example, by performing a predetermined connection operation, it is possible to establish a data link capable of bidirectional data communication with the monitor device 1.

The control unit 44 causes the display unit 43, which is a display unit, to perform an operation of displaying information that can specify the leaving state based on the SSID received by the reception unit.
Specifically, the control unit 44 specifies the corresponding icon identification information with reference to the state identification table t2 for the eighteenth to nineteenth places of the SSID where the bed leaving state information is set. For example, when receiving an SSID in which the information shown in FIG. 4 (iii) is set, the eighteenth to nineteenth digits of this SSID are “11”, so from the state identification table t2, “awake (wake up) “Icon d” can be identified.
The control unit 44 can specify a kanji name by decoding for the tenth to seventeenth digits in which the code information of the subject name is set. As a result, the subject name “Watanabe” can be specified from “12345678” in the tenth to seventeenth digits.
In addition, of the predetermined number of digits of the SSID, the first to sixth digits are facility specific information, the seventh to ninth digits are a monitoring device management number, and the 20th to 22nd digits are temperature information. 44 handles such information as it is.

Therefore, from the SSID shown in FIG. 4 (iii), the facility specific information “SS-200”, the monitoring device management number “101”, the subject name “Watanabe”, the leaving state “wake up (wake up)”, the icon identification information “icon d ", temperature" 20 ° C "can be extracted.
As a result, the mobile terminal 4 can display the moving-off state of each subject and the like based on the extracted information.
Specifically, as shown in FIG. 9, the management number of the monitoring device 1, the subject name, and the leaving state icon can be associated, and this association can be displayed in a list for each monitoring device 1.
For example, from Fig. 9, the subject "Maeda-sama" with management number "101" can grasp that it is awake (living) when he sees the bed leaving state icon, and similarly, management number "102" The subject "Suzuki-sama" is asleep, and the subject "Tanabe-sama" with the management number "104" can be grasped to be leaving the bed. In addition, based on the intensity of received radio waves such as beacons, icons capable of identifying the radio wave intensities can be associated and displayed (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, grasp the subject's bed leaving state and environment regardless of where in the facility where the beacon can be received. Can.

Further, in the bed leaving information processing system of the present embodiment, by accessing the monitor device 1 from the portable terminal 4, it is possible to obtain the past record of the subject's bed leaving state and environmental information and display the record in a viewable manner. .
Therefore, as shown in FIG. 11, in the monitor device 1, the storage unit 15 stores recording information in which the control information and the test subject are associated with the time-out state and the environmental information for each subject.
For example, in response to a request from the portable terminal 4, the sleep state of the subject can be displayed graphically.
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. The sleep state graph screen shown in FIG. 12 can be displayed by selecting the monitor device 1 of “101”.
In the sleep state graph, graphs of sleep states (during sleep and awakening) and sleep times of each day for the past week are displayed for each specific monitor device and each subject. Therefore, the subject's past sleep tendency can be easily grasped.
In addition, it is possible to display the presence or absence of the subject's current body movement signal.

By the way, data of a size which does not fit in the data frame of the SSID, such as recording of a fixed period in the past, is transmitted from the monitor device 1 to the portable terminal 4 or the portable device 4 transmits monitor data to the monitor device 1 etc. In the case of transmitting data, it is necessary to establish a data link between the portable terminal 4 and the monitoring device 1.
In this respect, when the SSID is changed and used as in the bed departure information processing system of the present embodiment, the connection request destination can not be identified from the portable terminal 4, and a data link is established with the desired monitor device 1. I can not
For this reason, in a predetermined case, the mode (fixed mode) for fixing the SSID can be set, and the SSID can be prevented from changing while the fixed mode is set.
For example, when it is desired to browse the sleep state graph, a predetermined connection operation can be performed by setting a fixed mode in advance and specifying a fixed SSID.

As described above, in the bed departure information processing system according to the present embodiment, the monitor device 1 electrically connected to the air bag sensor 2 for detecting the body movement of the subject, and the information transmitted from the monitor device 1 And the monitor device 1 generates an SSID based on the bed leaving state information and transmits it to the surroundings by including it in the beacon, so that it is in the beacon receivable area. The portable terminal 4 is configured to be able to confirm the subject's leaving state based on the SSID.
In such an out-of-bed information processing system according to the present embodiment, a network is constructed by the monitor device 1 and the portable terminal 4 located in the receivable area of the beacon constantly transmitted to the periphery from the monitor device 1. Can be introduced easily because it does not require
Further, for example, in the case where the bedded information processing system of the present embodiment is introduced to 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 etc. It is possible to check the patient's leaving condition etc. via the portable terminal 4 carried by oneself anywhere in the facility

Also, while omitting the connection process performed between the base unit and the handset of the wireless LAN, focus on the beacon constantly transmitted from the base unit to the surroundings, and include the floor state information etc. in the SSID included in the beacon. It enables quick and stable delivery of bed departure information.
The features of such a bed-up information processing system will be described with reference to FIG.
FIG. 10 (i) is a sequence diagram showing an operation in the bed-rising information processing system of the present embodiment, and FIG. 10 (ii) shows an operation of a wireless LAN normally performed between the monitor device and the portable terminal. FIG.
As shown in FIG. 10 (i), in the bed departure information processing system of the present embodiment, the portable terminal 4 receives a beacon constantly transmitted from the monitoring device 1, and predetermined information is received based on the SSID included in the beacon. It is made to display.
On the other hand, in the operation of the ordinary wireless LAN shown in FIG. 10 (ii), in addition to the transmission of the beacon, the connection request to the monitor device 1 from the portable terminal 4 and the monitor device 1 to the portable terminal 4 After the data link is established through such a connection process, it becomes possible for the portable terminal 4 to receive necessary information from the monitor device 1.
As a connection process (not shown), an operation of receiving a probe request from the portable terminal 4 which can not receive a beacon and transmitting a probe response to the probe request to the portable terminal 4 as an operation at the previous stage of connection request and connection response There is a case where an operation of mutually transmitting and receiving authentication information and the like may be included when performing the authentication of.

That is, according to the bedded information processing system of the present embodiment, the unidirectional communication (only transmission) is performed by including the SSID configured by the necessary information in the beacon without going through the normal connection process in the wireless LAN. Therefore, it is possible to quickly exchange information.
Further, as shown in FIG. 10 (ii), in the case of the method of performing data communication through the data link, disconnection of the data link and reconnection operation associated therewith occur when the reception strength of the radio wave is low or unstable. Problems occur when data can not be passed or delayed.
On the other hand, in the single-bed information processing system of the present embodiment, the mobile terminal 4 needs only to receive the SSID included in the beacon, so the SSID can be assured even when the reception intensity is low or unstable. Can be delivered to

(Alarm processing based on bedtime)
Next, alarm processing in the bed leaving information processing system will be described.
The alarm processing is processing for causing the portable terminal 4 to output an alarm when the bed departure time exceeds a predetermined time when the bed departure of the subject is detected.
In the monitor device 1 that enables this alarm processing, the control unit 16 operates as a bed departure detection unit to perform an operation of detecting that the subject has left the bed based on the biological information. The subject's leaving can be detected, for example, based on the determination by the leaving determination means, when the state of the bed changes from "bealing" or "wake up" to "becoming out".

Further, when the control unit 16 operates as an alarm determination unit, if bed separation is detected, whether the bed time detected by continuing the bed separation exceeds a predetermined time corresponding to the time when the bed is detected It is determined whether or not.
Specifically, the timer value is registered in advance in the monitoring device 1, and when bed departure is detected, it is determined whether or not the bed departure time exceeds the timer value.

The timer value can be registered based on the operation of the mobile terminal 4 in the following procedure.
For example, the target monitor device 1 is selected from the monitor devices 1 displayed on the list display screen (FIG. 9), and thereby the operation mode setting screen shown in FIG. .
In the operation mode setting screen, each time the "set" button is pressed, the timer value changes from "5 minutes" to "10 minutes" to "30 minutes" to "30 minutes" to "60 minutes" to "detailed mode" to "1 minute" to ... When the “action” button is selected after selecting a desired timer value, the setting data including the timer value is transmitted to the target monitoring device 1.

Further, by selecting the “detailed mode setting” button on the operation mode setting screen, the detailed mode setting screen (basic) shown in FIG. 13 (ii) is displayed.
In 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, setting data is transmitted to the target monitoring device 1.

When receiving the setting data from the portable 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 monitoring device 1, when the test subject's leaving is detected, the control unit 16 causes the clocking unit to start counting and measures the leaving time.
The control unit 16 determines whether the bed leaving time exceeds the timer value.

Then, when the bed leaving time exceeds the timer value, the control unit 16 transmits the notification information that causes the portable terminal 4 to output predetermined alarm information so that the portable terminal 4 can receive the notification information.
Specifically, the control unit 16 operates as the third information setting unit, thereby generating an alarm as third information corresponding to the number of digits in the third range (for example, the 23rd digit) in the predetermined number of digits of the SSID. The 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 portable terminal 4, it becomes possible to output a predetermined alarm 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 the present embodiment, when the bed leaving time exceeds a predetermined time according to the time when bed leaving is detected, an alarm can be output from the portable terminal 4.
Therefore, in the monitor device 1, an alarm determination table t3 in which the target time and the timer value are associated in advance is registered.
The alarm determination table t3 can be registered based on the operation of the mobile terminal 4 in the following procedure.

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

When receiving the setting data from the portable terminal 4, the monitor device 1 extracts association data of the time zone and the timer value from the setting data, and stores the association data as the alarm determination table t 3 in the storage unit 15. Thereby, the alarm determination table t3 shown in FIG. 14 is registered.
When the monitor device 1 detects the bed departure, the 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 detection of bed departure (S21). Specifically, “bedding up” is detected when the state of going up has changed from “behind” or “alertness (wake up)” to “being up”.
When the bed leaving is detected, the bed leaving detection time is acquired (S22), and the measurement of the bed leaving time (clocking) is started by the timer unit 14 (S23).
Then, it is determined whether the bed leaving time exceeds the time corresponding to the bed leaving detection time (S24).

In the alarm determination table t3 shown in FIG. 14, “target time: 14:00 to 16:00” and “timer value: 100 minutes” are set in “individual 1”, and “target 2” is “in target”. Time: 07:00 to 22:00 and “Timer value: 60 minutes” are set, and “Target time: 22: 01 to 06: 59” and “Timer value: 0 minutes” are set in “Individual 3”. It is set.
Therefore, for example, when the bed departure detection time is 15:00, the timer value of Individual 1 is referred to, and in this case, when the bed departure time exceeds 100 minutes (S24-YES), the alarm notification flag indicates the predetermined number of digits of the SSID. , And included in a beacon and transmitted (S25).
Also, when the bedfall detection time is 23:00, the timer value of Individual 3 is referred to, and in this case, when the bedtime exceeds 0 minutes (S24-YES), that is, immediately after the bedbreak detection, the alarm notification flag It is set to the predetermined number of digits of the SSID, and is included in a beacon and transmitted (S25).
In addition, although bed leaving was detected, when bed leaving time does not exceed the time corresponding to bed leaving detection time (S24-NO), S25 is skipped and it returns to the process from S21.

In this way, the portable terminal 4 that has received the beacon can output a predetermined screen display or sound based on the alarm notification flag included in the beacon.
Here, the beacon is constantly transmitted from the monitor device 1 to the surroundings.
Therefore, for example, in a facility such as a nursing home, when the area where the beacon can be received covers the entire facility, a manager or the like can quickly alert via the portable terminal 4 carried by himself regardless of where in the facility You can be notified.

In addition, since the receivable area of the beacon extends in the range of 100 m, it is possible to install the monitor device 1 so that the area extends to the 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 operating a vehicle that regularly or randomly passes a road around the facility, when the vehicle passes the road around the facility, the driver of the vehicle An alert can be notified to the portable terminal 4 carried.
Therefore, it is possible to provide a service capable of monitoring a subject from outside the facility without using an external network.

Further, in the alarm determination, the bed leaving time serving as the determination reference is set to a length corresponding to the bed leaving time (short at night, long at daytime) for the following reason.
That is, in general, since the subject is awake during the daytime for a long time, shortening the bedtime may misjudge normal behavior as a target to be alerted. On the other hand, it is normal for the subject to stay in bed at night, and there is a possibility of chewing if the bed is detected at night, especially when the subject is elderly. In addition, because the surroundings are dark at night, it is more difficult to find as the first action such as the search is late for the whale.
For this reason, by setting the bedtime to be the reference of the alarm determination short in the night and long in the daytime, it is possible to detect a habit with high precision and to promptly respond to a habit at night.

(Encryption of SSID configuration information)
Next, encryption of configuration information of the SSID will be described.
The SSID of the monitoring device 1 is received by the portable terminal 4 located in the coverage area of the beacon emitted from the monitoring device 1, but this SSID is another unspecified wireless LAN handset within the same area. It can be easily viewed by
In this regard, the SSID in the present embodiment is problematic because it includes data related to privacy such as the subject name.

Therefore, in the detached bed information processing system of the present embodiment, it is possible to add a configuration in which the monitor device 1 encrypts the configuration information of the SSID and the portable terminal 4 decodes the configuration information of the SSID.
Specifically, in the monitoring device 1, the control unit 16 operates as an encryption unit to encrypt the subject name, leaving state information, and the like, generate an SSID based on the encrypted information, and use this as a beacon. Include and send.
In the portable terminal 4, the control unit 44 operates as a decoding unit, thereby performing decoding processing on the SSID included in the received beacon, and thereby, it is possible to restore information that can specify the leaving state and the like.
In this way, it is possible to prevent interception of the configuration information of the SSID, and the secrecy can be enhanced.

Further, in the encryption / decryption process, a password, a serial number unique to the monitor apparatus 1, a MAC address or the like can be used as a common key.
For example, by using a facility common password as the common key, setting of the key can be facilitated and operations such as password management can be simplified.
In this case, if the password is known to a third party, the information on all the subjects in the facility is decoded, and the damage by the leakage may be enormous.
For such problems, damage can be minimized by using product-specific information such as a password provided for each monitoring device 1, a product number, and a MAC address 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 information other than the product unique information can be included in the SSID without being encrypted.
When the management number and the serial number of the monitor device 1 are included in the SSID, the management number is not encrypted, and other configuration information including the serial number used as a common key is encrypted, and these non-encrypted information and the encryption Configuration information as an SSID.
In this way, although a third party can intercept the management number of the monitoring device 1 from the SSID included in the beacon, it does not matter because the management number is not information that would be disadvantageous to the subject, The common key serial number and subject name can not be intercepted because they are encrypted.
In this case, in the portable terminal 4, table data in which the management number of the monitor device 1 and the serial number are associated with each other is stored in advance.
When a beacon is received, the corresponding serial number can be 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 serial number as a decryption key.
According to such encryption / decryption processing, it is possible to provide an out-of-bed information processing system that is more secure and has excellent convenience.

(Aspect as information processing device)
In the above, the bed leaving information processing apparatus, bed leaving information processing system, and bed leaving information processing program that enables identification of the subject's bed leaving state based on the biological information related to the bed leaving state has been mainly described. The present invention can also function as an information processing apparatus that sets an SSID based on various pieces of fluctuation information detected by various methods as well as biological information, and includes this in a beacon for transmission.
Specifically, the control unit 16 operates as a setting unit, and based on the variation information detected by the detection unit such as a sensor, specific information corresponding to the number of digits of the specific range among the predetermined number of digits of the SSID Set
Then, the control unit 16 causes the wireless communication unit 13 as the transmission means to transmit the SSID in which the specific information is set, in the beacon.
As a result, the mobile terminal 4 in the beacon receivable area can receive the SSID via the beacon, and can identify the variation information based on the specific information constituting the SSID.

As fluctuation information, water level information detected by a water level sensor, movement information of a person or an object detected by an optical sensor, and a size and frequency of a sound detected by a sound sensor are assumed.
Among them, for example, the case where the water level sensor provided on the seawall of the coast is connected to the monitoring device 1 installed in the residential area near the coast will be described.
In this case, the water level information from the water level sensor is periodically or irregularly input to the monitoring device 1, and the monitoring device 1 specifies 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 to third digits) is set.
Then, the monitor device 1 includes the SSID configured by the water level information in the beacon and transmits it to the surroundings.
In this way, the residents living in the beacon reception area can immediately know the water level information via the portable terminal 4 carried by itself.
For this reason, it is possible to respond promptly and appropriately to disasters caused by tsunamis and large waves caused by typhoons.

In addition, since the beacon generated based on the floor condition information is included in the beacon and data communication is performed without passing through a predetermined connection process between the master unit and the slave unit of the wireless LAN, information transfer can be performed quickly. It is possible to do

On the other hand, in the conventional bed leaving information processing apparatus, when the subject's bed leaving information is transmitted to the portable terminal using a wireless LAN, a connection operation based on a predetermined connection process is performed, and the data link established by this connection operation is performed. The bed departure information is transmitted to the portable terminal.
That is, prior to data transfer, it is necessary to go through the connection process, which has been a factor that impedes rapid processing.
In addition, for areas with low signal strength and unstable areas, it is not possible to stably receive leaving information, and the connection process is repeated to establish a data link, which further hinders quick processing. It had become.
In particular, when the bed leaving information for a plurality of subjects is delivered to the portable terminal, the above-described process is performed in parallel, and thus the above problem is more apparent.

For example, regarding the setting of the SSID, the second information can be set in a portion including the first digit number among the predetermined digit number, and the first information can be set in the digit number portion thereafter.
That is, the information to be set including the first information and the second information can be set to an arbitrary number of digits.

Further, as shown in FIG. 16, the bed-to-bed information processing system of the present invention can be communicably connected to an external network such as the Internet via a wireless LAN router.
Furthermore, by setting the monitoring device 1 in the router mode, connection can be made with an external network without using 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) records of the bed leaving state and environmental information from each monitor device 1 and to display a list.
