FIG. 5 is a configuration diagram showing the concept of communication unit 103 and communication unit 113 in an embodiment of the present disclosure.
The communication unit 103 and the communication unit 113 are equipped with an FSK (Frequency Shift Keying) modulation method and a LoRa (Long Range) modulation method. It is possible to use FSK and LoRa differently depending on the radio wave environment.
LoRa is a low-power wide area wireless communication (LPWA) technology for IoT (Internet of Things) that uses a unique modulation method called chirp spread spectrum to communicate over long distances with low power consumption. It is a communication standard that is one of the technical standards.

The communication unit 103 and the communication unit 113 have a frequency of 900 MHz band and a frequency of 400 MHz band. Depending on the radio wave environment, it is possible to use a frequency in the 900 MHz band or a frequency in the 400 MHz band.

Carrier sense is a method of checking before starting data transmission to see if another wireless station is using the same wireless resource. This mechanism avoids interference by not transmitting on the same frequency.

In the present disclosure, carrier sensing is performed within either a 900 MHz band frequency or a 400 MHz band frequency.
In the case of the FSK modulation method, if the radio resource to which data is to be transmitted is being used by another radio station, the station moves to use a radio resource of another frequency. On the other hand, since the LoRa communication method has a wide band, the FSK modulation method is used.

FIG. 6 is a configuration diagram showing the concept of the sensor unit 116 in an embodiment of the present disclosure.
The sensor section 116 includes a humidity measuring means and a position information measuring means.
The humidity measuring means includes a thermohygrometer 116A. Further, the position information measuring means includes a 3-axis accelerometer 116B, a 3-axis gyroscope 116C, and an atmospheric pressure gauge 116D.

The thermohygrometer 116A measures the temperature and humidity around the thermohygrometer. Since the information processing terminal device 110 is installed inside the diaper, the temperature and humidity inside the diaper differ greatly between when there is excrement inside the diaper and when there is no excrement inside the diaper.
Generally, immediately after excrement is removed, the temperature and humidity inside the diaper rise rapidly. After a while, the temperature drops, but the humidity remains high.
There are several types of hygrometers, but electric hygrometers using semiconductors are used. Air hygrometers use capacitive and resistive polymer membranes used for public weather observation.
Note that humidity represents the relative humidity ratio of the amount of water vapor in the air.

The three-axis accelerometer 116B is a sensor that measures acceleration in the X direction, Y direction, and Z direction. The three-axis accelerometer 116B can detect diaper movement, vibration, and impact by measuring acceleration and performing signal processing.
Specifically, by processing the acceleration measured by the 3-axis accelerometer 116B, the changes from lying in bed to standing up, movements when going to the toilet, movements when falling, etc. It is possible to detect.

The 3-axis gyroscope 116C is a sensor capable of detecting the direction of rotation. The three-axis gyroscope 116C detects rotation by synchronously detecting signals caused by Coriolis force and determining angular velocities in the X direction, Y direction, and Z direction.
Specifically, by processing the angular velocity measured by the three-axis gyroscope 116C, it is possible to detect rotation during a fall.

The atmospheric pressure gauge 116D is a sensor that detects height differences. Specifically, by processing the atmospheric pressure measured by the atmospheric pressure gauge 116D, it is possible to detect movements when sitting or standing up on the toilet, movements when falling down, etc.
In addition, because atmospheric pressure can affect a person's physical condition and health status, it is meaningful to measure atmospheric pressure.

The information processing terminal device 120 is an information processing terminal device that is attached to a toilet paper roll.
People in need of care can go to the bathroom and relieve themselves even if they are wearing diapers. Use toilet paper when doing so. The information processing terminal device 120 rotates due to the rotation of the toilet paper roll. It is possible to detect which care recipient (information processing terminal device 110) is going to the toilet.
Note that the person requiring care may be at home or may be at a nursing care facility.

FIG. 7 is an example of a data structure 140 of information transmitted from the information processing terminal device 110 to the information processing device 100.
The control unit 111 stores the data acquired by the sensor unit 116 in the storage unit 112. The data structure 140 is the structure of data stored in the storage section 112. The data format may be text format, csv format, or XML format.
The time at which information in the data structure 140 is first detected is recorded. Next, in order to determine which information processing terminal device 110 the information belongs to, the terminal ID assigned to the information processing terminal device 110 is recorded. The temperature and humidity methods are then recorded. Accelerations in the X, Y, and Z directions are then recorded. The angular velocities in the X, Y, and Z directions are then recorded. Finally, the atmospheric pressure is recorded.

The communication unit 103 of the information processing device 100 receives data transmitted from the communication unit 113 of the information processing terminal device 110. CRC16 may be used to confirm the normality of data. If the data cannot be received normally or if the data cannot be received, the information processing device 100 may request the information processing terminal device 110 to resend the data.
Further, the communication unit 113 may encrypt the transmitted data. Encryption prevents data containing personal information from being intercepted or tampered with. The communication unit 103 decodes it when receiving it. The encryption method is, for example, AES128.
Note that the transmission data may be compressed.

After the communication unit 103 receives the data, the control unit 101 stores the data in the storage unit 102.
The control unit 101 calculates position information according to a predetermined moving average. Determine whether the person is lying, standing, or sitting. At this time, consideration may be given to the subject's height, health condition (ambulatory, wheelchair, crutches, cast, etc.).

The information processing device 100 can perform machine learning on data stored in the storage unit 102. By using AI technology such as deep learning through the Internet, it is possible to learn the daily life behavior patterns of the information processing terminal device 110.
That is, the information processing device 100 can predict when and where the information processing terminal device 110 will excrete by performing machine learning using excrement information, location information, date and time, etc. as training data. can.
More specifically, for example, the caregiver can grasp daily behavior patterns such as "the care recipient goes to the toilet and relieves himself at around 00:00 every day."

The information processing device 100 may issue an alarm.
For example, if the height information (Z) has fallen by 50 cm even though the person has not moved since processing the position information (X, Y, Z) (there is little change in X, Y), there is a possibility that the person has fallen. is possible. In such cases, it is necessary to rush immediately. Therefore, the information processing apparatus 100 may issue an alarm and display it on the display unit 104. Alternatively, an alarm sound may be emitted to alert those around the information processing device 100.
Note that the power of the information processing terminal device may be turned off when changing the diaper.

Regarding temperature and humidity, when a certain temperature threshold value and a certain humidity threshold value are exceeded, an alarm may be issued to indicate that it is time to change the diaper. For example, the temperature threshold may be 30° C., and the humidity threshold may be 80%.
Instead of the condition that the humidity exceeds a certain threshold, an alarm may be issued to indicate that it is time to change the diaper when the rate of change in humidity exceeds a predetermined value.

FIG. 8 is an example of a data structure 150 of an alarm issued by the information processing device 100.
Displays the time when the event first occurred. Next, in order to determine which information processing terminal device 110 the information belongs to, the terminal ID assigned to the information processing terminal device 110 is recorded.
Next is the importance of the alarm. Not all alarms have the same importance/urgency. It is normal for each event to have a different degree of importance and urgency. For example, it is possible to set the most important item to fall, which is red, and the most important item, which is diaper changing, which is yellow.

The alarm ID is an identifier for identifying an alarm. The alarm details are detailed information of the alarm. Next is how to deal with the alarm. Remedies for alarms include changing diapers and rushing to the hospital immediately. The confirmation box is a flag indicating whether or not a countermeasure for the alarm has been implemented. If there are multiple care assistants, it is necessary to clarify who did what and when. It may also be managed in association with the responder. The response completion time is the time when the response was completed and the alarm was released.

FIG. 9 is a flowchart of the information processing terminal device 110 in an embodiment of the present disclosure.
When the information processing terminal device 110 is powered on, the control unit 111 starts an initial program and transitions to a state where excrement, position information, and toilet information can be detected (S10).
Note that the toilet information refers to information on the patient's use of the tray based on the use of toilet paper.

The sensor unit 116 receives instructions from the control unit 111 and detects excrement information (S20), position information (S21), and toilet information (S22) at predetermined intervals.

The excrement information is measured by a thermohygrometer 116A. The humidity is relative humidity (S20). Position information is measured by a 3-axis accelerometer, a 3-axis gyroscope, and an atmospheric pressure gauge (S21). Toilet information is measured by a 3-axis gyroscope. The measured information is stored in the storage unit 112 in a data structure 140.

After the information is stored in the storage unit 112 for a certain period of time, the communication unit 113 receives a command from the control unit 111 and prepares to transmit the data to the information processing device 100.
First, the frequency, ie, either the 400 MHz band or the 900 MHz band is selected (S30).
Next, the modulation method, ie, FSK or LoRa, is selected (S40).

Next, carrier sense is used to check whether wireless resources for transmitting data are available (S50).
If a wireless resource is available, the wireless resource is allocated (S60) and the data is transmitted as is (S70).
If the radio resource is not available, the process returns to frequency selection, modulation scheme selection, and finding and allocating another radio resource.

The communication unit 103 of the information processing device 100 receives data from the information processing terminal device 110 (S80).
The storage unit 102 of the information processing device 100 receives the command from the control unit 101 and stores the received data (S90).

The control unit 101 processes the data according to a predetermined moving average to calculate excrement information, position information, and toilet information (S100).

Based on the excrement information, if the diaper needs to be changed, the control unit 101 may issue an important alarm and display it on the display unit 104 (S110).
If it is determined that the patient has fallen based on the position information, the control unit 101 may issue the most important alarm and display it on the display unit 104. Further, the information processing device 100 may generate an alarm sound to alert the surroundings.
