Description

  The present invention relates to a care system, a data processing method, a sensor information processing system, and a transceiver, and in particular, a sensor that detects a state of a care receiver or the like in a care system by a sensor and notifies the sensor information according to the detected sensor information. Information collection and processing.

  As an important treatment in a care facility, there is a work of changing a diaper of a care receiver. Conventionally, a care giver (sometimes called a care staff) goes to the care giver's room to check the condition of the diaper, or to periodically call the care giver's push button switch operation (nurse call). The method was to take a patrol to confirm the situation.

  Recently, a management computer (or personal computer (PC)) that detects urination by using a urine sensor in order to reduce the burden on the caregiver and replace the diaper at the optimal time when the caregiver excreted However, there is known a system for reporting urination detection to a mobile terminal carried by a caregiver (see Patent Documents 1 and 2).

  According to the nursing care systems described in Patent Documents 1 and 2, a message is transmitted from a management computer to a mobile terminal held by a caregiver as voice information and character information, and voice output and character display are performed on the mobile terminal. Or it is displayed on the display of the personal computer. However, when the mobile terminal receives the message, the caregiver may be under treatment because the caregiver is under treatment, and the mobile terminal may not immediately be able to deal with the message. Moreover, the display of the personal computer is generally watched by the administrator, and not all caregivers see it each time. Furthermore, since the message is usually notified when the management computer determines that the diaper should be replaced, the caregiver does not know the condition of the diaper of the cared person except at that time. Therefore, it is convenient for a nursing facility or a caregiver if the state of the care recipient detected by a urine sensor or the like can be visualized at all times.

  Further, a telephone exchange (PBX) is generally used to notify a PHS or a mobile phone of a caregiver of a message of voice information. Therefore, rather than the management computer and the personal computer (PC) acquiring information from the sensor and performing determination and notification processing such as diaper replacement as described in Patent Documents 1 and 2, We thought that it would be simple and effective if the sensor information could be received and processed using the function of the PBX, such as a telephone interface.

Embodiments of the present invention will be described below with reference to the drawings.
A nursing care system according to an embodiment will be described with reference to FIG. A nursing care system is realized by applying a sensor information processing system or a sensor information processing method to a nursing care facility.

  In the care system shown in FIG. 1, a telephone exchange (private branch exchange: PBX) 100 includes a nurse call interface package (nurse call IF package) 101, an intercom interface package (intercom IF package) 102, an in-house PHS parent device interface package (in-house PHS). It has a master device IF package 103, multi-function telephone interface packages (multi-function telephone IF packages) 104 and 105, a central control unit (CCU) 106, and a processing unit 107. Here, the multifunction telephone IF packages 104 and 105 have a multifunction telephone interface. Here, the multi-function telephone is a telephone connected to a telephone exchange, and particularly refers to a telephone that enables an extension telephone within a premises.

  The nurse call IF package 101 is connected to the server 109 arranged in the nurse call system 108. The server 109 is connected to the grip button 110 with a microphone / speaker and accepts a nurse call. The intercom IF package 102 is connected to an embedded intercom 112 arranged in the staff call system 111. The on-premise PHS master device IF package 103 is connected to the BS antenna 113 and makes a call via the PHS 114 owned by the care staff. The multifunction telephone IF package 104 is connected to the multifunction telephone 116 arranged in the office 115.

  The multi-function phone IF package 105 is connected to a multi-function phone 118 installed in a common facility 117 such as a dining room or a rest area. The multi-function telephone 118 has a configuration capable of multi-connection (multi-setting A, multi-setting B). For example, the sensor receiver 121 is connected to the multi-setting B of the multi-function telephone 118. The sensor receiver 121 has the same multifunction telephone interface as the multifunction telephone interface of the multifunction telephone IF package 105. Here, since the multi-function telephone 118 has a configuration capable of multi-connection, it is possible to receive sensor information from the sensor receiver 121 and make a normal call according to the setting.

  Further, the sensor receiver 120 is directly connected to the multifunction telephone IF package 105. The sensor receiver 120 has the same multifunction telephone interface as the multifunction telephone interface of the multifunction telephone IF package 105. Hereinafter, the sensor receivers 120 and 121 may be collectively referred to as the sensor receiver 12.

  A sensor 13 is connected to the sensor receiver 12 wirelessly or by wire. The sensor 13 includes a plurality of sensors. For example, a diaper sensor worn by the care recipient, a temperature and humidity sensor installed in the resident's room 14, an image sensor that detects the movement of the care recipient, a voice sensor that detects the voice of the care recipient, a door of the living room. There are open / close sensors, body temperature sensors that detect the temperature of the cared person, and so on. There are two types of diaper sensors: urine sensor and stool sensor.

  The sensor receiver 12 receives sensor data (sensor information) detected by the sensor 13 via a general-purpose interface. Here, as the general-purpose interface, LAN, USB (Universal Serial Bus) or the like is used for wired, and Wifi (registered trademark), Bluetooth (registered trademark) or the like is used for wireless.

  The processing device 107 is a data processing device mounted in the PBX 100, and exchanges information with the central control device 106 via a bus to perform data processing. The processing device 107 may be called a built-in PC (personal computer). The processing device 107 has a processing unit and a storage unit. The processing unit is a processor that processes data, and the storage unit stores various management tables for processing the sensor information detected by the sensor 13 (this will be described later). The storage unit also stores the measurement data of each sensor included in the sensor information.

  The central controller 106 collects sensor information from the sensor receiver 120 or sensor information from the multifunction telephone 118 via the multifunction telephone IF package 105. The collected sensor information is transferred to the processing device 107 and processed there. Based on the processing result of the sensor information by the processing device 107, the central control device 106 causes the nurse call IF package 101, the intercom IF package 102, the in-house PHS master device IF package 103, the multifunction telephone IF package 104, and the multifunction telephone IF package. The call processing or message sending processing is performed on 105.

  More specifically, the processing unit of the processing device 107 executes an application program and analyzes the sensor information and statistics the sensor information while referring to the sensor information management table and the sensor call condition management table. The central control device 106, based on the processing result of the sensor information by the processing device 107 and the information managed in the sensor call condition management table, the nurse call IF package 101, the intercom IF package 102, the in-house PHS master device IF package 103, The multifunctional telephone IF package 104 is specified and processing such as reporting and message transmission is performed. In addition, control information for displaying the display element 707 is transmitted from the multifunctional telephone IF package 105 to the sensor receiver 120 via the telephone interface.

  The central controller 106 can be connected to the external server 151 or the cloud 152 via the LAN. For example, the processing device 107 may be connected to the server 151 or the cloud 152 via a LAN, and a part or all of the processing such as the analysis performed by the processing device 107 may be performed by the server 151 or the cloud 152. When the processing device 107 performs processing as described above, the contents of the management table of the processing device 107 are rewritten and various instructions are given using the input device and the display device (not shown) of the server 151. Can be entered.

Next, a communication system in the telephone exchange 100 will be described.
With regard to the communication method, as a minimum necessary function as an interface of the multi-function telephones 116 and 118, a call is made with an interface capable of transmitting and receiving data such as normal outgoing / incoming calls, button control, LCD control and telephone directory control. For using voice communication interface.

[Communication system between multi-function telephone IF package 104 and multi-function telephone 116]
A communication method between the multi-function telephone IF package 104 and the multi-function telephone 116 will be described with reference to FIG.

  Normally, the multifunction telephone 116 transmits voice information (voice data (PCM: Pulse Code Modulation)) to the multifunction telephone interface package 104 using the B channel as the multifunction telephone interface. In addition, the multi-function phone 116 transmits control information (control data of LCD or the like) to the multi-function phone interface package 104 by using the D channel as a multi-function phone interface.

  The communication method between the multi-function telephone IF package 104 and the multi-function telephone 116 is a general ping-pong transmission method. The mounting line uses the AMI (Alternate Mark Inversion) coding method. The AMI code system is one of the coding systems used in digital communication, and is a system in which positive and negative polarity codes are alternately transmitted every time "1" occurs.

Here, the ping-pong transmission method is the following method.
Generally, ISDN (Integrated Service Digital Network) supports two B channels of 64 kbps and one D channel of 16 kbps, but if a control signal is added to this, a total transmission rate of 160 kbps is required. Since data transmission at 160 kbps in full duplex and in both directions must be performed between the telephone station and the subscriber's house, communication is performed using a method called ping-pong transmission on a pair of copper wires. In this system, the transmission bit rate is doubled to 320 kbps (time axis compression) to enable transmission in half the time, and data is alternately transmitted from the telephone station and the subscriber's house. To be precise, it is called a time-division control transmission method (TCM: Time Compress Multiplexing).

  In FIG. 2, F is a start bit (frame synchronization), which is always “00”. B1 is a B1 channel (64 kbps), and voice data (PCM) is transmitted via the B1 channel. B2 is a B2 channel (64 kbps), and voice data (PCM) is transmitted via the B2 channel. MF is always "0". D is data (16 kbps) and is, for example, control data for an LCD or the like. P is a parity (even number).

  In the format as shown in FIG. 2, audio data is transmitted / received for two channels (64 kbps × 2) via the B channel. In addition, control data such as LCD is transmitted and received at 16 kbps.

  The communication method between the multi-function telephone IF package 105 and the multi-function telephone 118 has a configuration in which the multi-function telephone 118 is capable of multi-connection (multi-setting A, multi-setting B). (Transmission / reception of information) is the same as the communication method between the multi-function telephone IF package 104 and the multi-function telephone 116. On the other hand, when the multifunction telephone 118 is set to receive the sensor information, the same communication method as the communication method of the sensor receiver 120 and the multifunction telephone IF package 105 described below is used.

[Communication system between sensor receiver 120 and multi-function telephone IF package 105]
A communication system between the sensor receiver 120 and the multi-function phone IF package 105 will be described with reference to FIG.
Data transmission / reception is performed between the sensor receiver 120 and the multifunction telephone IF package 105 by using the data transmission / reception method of the multifunction telephone IF package 105 and using sensor information instead of voice information of the multifunction telephone 116. .

  The sensor receiver 120 transmits the sensor information constantly output from the sensor 13 to the multifunction telephone IF package 105 by using the B channel as the multifunction telephone interface. Further, the sensor receiver 120 transmits the sensor information intermittently output from the sensor 13 to the multifunction telephone IF package 105 by using the D channel as the multifunction telephone interface.

  Specifically, the B channel is used for transmitting and receiving sensor information (always occurring sensor information) that requires a relatively wide band and requires real-time property instead of voice information. Then, the D channel is used for transmitting / receiving sensor information (intermittently generated sensor information) that does not require real-time data transmission / reception and has a small amount of data.

  In FIG. 3, F is a start bit (frame synchronization), which is always “00”. B1 is a B1 channel (64 kbps), and sensor data (for Bch) is transmitted via the B1 channel. B2 is a B2 channel (64 kbps), and sensor data (for Bch) is transmitted via the B2 channel. MF is always "0". D is sensor data (16 kbps) for Dch. P is a parity (even number).

  In the format as shown in FIG. 3, sensor data constantly output from the sensor 13 is transmitted / received for two channels (64 kbps × 2) via the B channel. The sensor data intermittently output from the sensor 13 is transmitted / received at 16 kbps through the D channel.

  Regarding the multi-function telephone 118 to which the sensor receiver 121 is connected, if it is set to receive sensor information, the same communication method as the communication method between the sensor receiver 120 and the multi-function telephone IF package 105 is used. A communication method is used. Specifically, the multi-function telephone 118 uses the B channel as an interface for the multi-function telephone to transmit the sensor information constantly output via the sensor receiver 121 to the multi-function telephone IF package 105. Further, the multi-function telephone 118 uses the D channel as a multi-function telephone interface to transmit sensor information intermittently output via the sensor receiver 121 to the multi-function telephone IF package 105.

Here, FIG. 4 shows an example of contents of the D channel (Dch) for the sensor.
As shown in FIG. 4, the contents of the sensor Dch are sensor type, sensor ID (identification number), receiver ID (identification number), priority type, mode, message number, and sensor data.

FIG. 5 shows an example of the contents of the B channel (Bch) for the sensor.
As shown in FIG. 5, the contents of the Bch for sensor include start frame, sensor type, sensor ID (identification number), receiver ID (identification number), priority type, mode, BCC, end frame, sensor data (video, Voice, temperature, etc.).

[Communication method between multi-function telephone IF packages 104 and 105 and central controller 106]
The communication system between the multi-function telephone IF package 104 and the central control unit 106 is the communication system in the telephone exchange 100, and it is necessary to surely communicate with a fixed band without delay. Therefore, there is a need for a method that ensures a fixed band.

  In addition, since communication in the control system is irregular and the amount of communication changes, a communication system similar to request, answer, and packet transmission is adopted. As shown in FIG. 6, frame transmission / reception for link access of the D channel is performed by a procedure under software control.

  As shown in FIG. 6, a request (REQ) is sent from the multi-function telephone IF package 104 (L / T # 0) to the central controller 106. The central controller 106 sends ANS = 1 to the multifunction telephone IF package 104. At this time, the central control unit 106 returns an ACK because the buffer is empty.

  Next, the multi-function phone IF package 104 transmits the L / T control packet (SD) to the central controller 106. The central control unit 106 sends the L / T control packet ACK (SDACK) and ANS = 0 to the multi-function telephone IF package 104 after the normal reception and the reception process is completed.

  The multi-function phone IF package 105 (L / T # 1) sends a request (REQ) to the central controller 106. The central controller 106 does not return an ACK because there is no buffer empty. The central controller 106 sends ANS = 1 to the multifunction telephone IF package 105. The multi-function phone IF package 105 transmits an L / T control packet (SD) to the central control unit 106. The central control device 106 sends the L / T control packet ACK (SDACK), ANS = 0 to the multi-function telephone IF package 105 after the L / T control packet (SD) is normally received and the reception process is completed.

[Configuration of sensor receiver 12]
Next, a block configuration of the sensor receiver 12 will be described with reference to FIG.
The microprocessor 700 has a UART (Universal Asynchronous Receiver Transmitter), a sensor interface (IF) such as USB and LAN, an I / O, a serial IF, and a bus. The sensor IF module 701 is connected to the sensor IF. Here, the sensor IF is a general-purpose interface, and if wired, LAN or USB is used, and if wireless, Bluetooth (registered trademark) or the like is used. The sensor 13 is connected to the sensor IF module 701. The microprocessor 700 is a processing unit, and displays based on transmission / reception control of sensor information received via the sensor IF 701 and other interfaces and control information transmitted from the central control unit 106, and control information transmitted from the CCU 106. The element 707 (display portion) is subjected to display control (light emission control).

  The contact drive circuit 702 is connected to the I / O, and the contact connector 703 is connected to the contact drive circuit 702 for contact output. A level (LVL) conversion circuit 704 is connected to the I / O, and a contact connector 705 is connected to the LVL conversion circuit 704 for contact input. Here, the contact connector 705 is, for example, a terminal that receives sensor information of a door sensor that detects opening and closing of a living room door, and the contact connector 703 is a terminal that transmits a control signal for automatically locking the living room door.

The I / O is also connected with a multi-connection switching switch (SW) 706, and a display element 707 for displaying the state of excretion of the care recipient's diaper detected by a sensor and the temperature and humidity of the living room. . Here, the display element 707 is an LED capable of displaying a plurality of colors, and as a result of processing the sensor information by the processing device 107, the LED is caused to emit light in a predetermined color according to the control information. The care staff can recognize the state of excretion of the diaper of the care receiver and the degree of danger due to the temperature and humidity in the living room by visually observing the emitted color. In other words, the display unit realizes "visualization" of the sensor information in the care facility. (This will be described in detail later.)
A program storage area 708 and a work area 709 are connected to the bus.

  The serial interface (IF) is connected to the ping-pong transmission / reception interface (IF) circuit 710 via the B channel (Bch: 64K) and the D channel (Dch: 16K). The ping-pong transmission / reception IF circuit 710 is connected to the transformer 711, the noise filter 712, and the RJ11 modular connector 713. The RJ11 modular connector 713 is connected to the multi-function telephone IF package (DLIN) 105. An RJ11 modular connector 714 is connected to the noise filter 712. The RJ11 modular connector 714 is multi-connected to the multi-function telephone 118. For example, it is connected to the multi-setting B of the multi-function telephone having the multi-setting A and the multi-setting B (see FIG. 1).

  As such, the sensor receiver 12 has an interface similar to the multifunction telephone interface of the multifunction telephone interface package 105. Specifically, by connecting a serial interface (IF) and a ping-pong transmission / reception interface (IF) circuit 710 via a B channel (Bch: 64 Kbps) and a D channel (Dch: 16 Kbps), a multifunction telephone The interface 750 (a portion surrounded by a dotted line in FIG. 7) is configured. At this time, sensor information is transmitted and received between the sensor receivers 121 and 120 and the multifunction telephone set IF package 105 instead of the voice information of the multifunction telephone set 116.

Here, the B channel (Bch) is used for transmitting and receiving sensor information (always occurring sensor information) that requires a relatively wide band and requires real-time property instead of voice information. On the other hand, the D channel (Dch) is used for transmitting / receiving sensor information (intermittently generated sensor information) that does not require real-time data transmission / reception and has a small amount of data.
Although the sensor receiver 12 is referred to in this embodiment, it may be called a transceiver because it transmits and receives sensor information and control information.

FIG. 8 shows the appearance of the sensor receiver 12.
The components such as the microprocessor 700 of the sensor receiver and the display element 707 shown in FIG. 7 are housed in the case of FIG. That is, the case of the sensor receiver 12 includes a dome-shaped upper case 121 made of polo carbonate (PC), a bottom cover 122 on which the components of the sensor receiver are mounted, and three integrally formed bottom covers 122. It is configured to include a leg 123 and a bottom lid convex portion 124. Since the upper case 121 is a transparent or translucent plastic member such as polycarbonate, when the display element 707 inside emits light of various colors, the display color can be visually recognized from the outside.

  Since the bottom cover 122 is provided with the three legs 123, the case of the sensor receiver 12 can be placed on a table such as the living room of the care receiver. In addition, by providing a hook (not shown) such as a hole or a metal fitting on the bottom lid convex portion 124, this case can be locked to a hook metal fitting or the like provided in the care receiver's living room or its outer wall. If the sensor receiver 12 is installed in the living room or its outer wall, the care staff only needs to look at the color displayed by the display element 707 of the sensor receiver 12 to check the state of the diaper of the care receiver in the living room. The temperature condition of the living room can be easily recognized. This makes it possible to “visualize” sensor information in nursing care facilities.

[Management table configuration]
Next, configurations of various management tables will be described with reference to FIGS. 10A shows a sensor information management table, and FIG. 10B shows a receiver management table. FIG. 11 shows a sensor call condition management table. These management tables are held in the storage unit included in the processing device 107.

  The sensor information management table illustrated in FIG. 10A illustrates a sensor ID for identifying a sensor, a sensor type indicating a sensor type, a user ID indicating a user (care recipient) of the sensor, and a sensor call condition. Register patterns such as excretion patterns and temperature patterns. The content of the sensor call condition management table is indexed by the above pattern indicating the sensor call condition. Since the temperature sensor is not directly attached to the user but is installed in the room where the user is, the location ID for identifying the room may be registered in the "user" field.

  The receiver management table shown in FIG. 10B manages sensor IDs that the sensor receiver 12 receives, and shows the receiver IDs that identify the sensor receivers and the installation locations of the sensor receivers. Register the receiver name and the sensor ID of the reception target. When the number of sensors worn by the cared person or the number of sensors installed in the living room increases or decreases, the registration of the sensor ID of the reception target increases or decreases accordingly.

  The sensor call condition management table shown in FIG. 11 is a table that defines a condition (pattern) such as a treatment according to the information detected by the sensor (sensor information), that is, an alarm. FIG. 11 (A) shows the alerting condition according to the excretion pattern which is the sensor information detected by the diaper sensor, and FIG. 11 (B) shows the alerting condition according to the temperature pattern which is the sensor information detected by the temperature sensor. Indicates.

  The sensor call condition management tables shown in FIGS. 11 (A) and 11 (B) are both notifications indicating a pattern ID for identifying a pattern, a time zone in which measures such as reporting are performed, a reporting condition, and a reporting time. The time, the extension number of the telephone as the notification destination, the display color displayed by the display element 707 provided in the receiver 12, the ring tone indicating the type of melody of the extension telephone, and the like are registered. The display element 707 displays the designated color for the notification time. In the example of FIG. 11 (A), excretion patterns 1 and 2 have different alarm conditions. This is because the amount of urine detected by the urine sensor differs depending on the care recipient, and the reporting condition is changed according to the amount of urine detected by the urine sensor. For example, at the time of the first urination, the amount of urine is small and it is not necessary to replace the diaper. Therefore, the notification time for notification is as short as 1 minute. Notification time becomes 5 minutes, and the color of the display element 707 also changes to red. The care staff senses a change in the melody received by the telephone he / she owns and / or a change in the display color of the display element 707, and treats the diaper exchange.

  In the example of the temperature pattern shown in FIG. 11B, when the temperature of the living room detected by the temperature / humidity sensor is 20 to 28 degrees C, the alarm is not issued, but is issued when the temperature is above or below the range. Since the temperature and humidity control of the living room often affects the health condition of the care recipient (for example, the occurrence of a cold etc.), the reporting condition is changed according to the slight change in the temperature. The notification time for alerting, the ring tone, and the display color of the display unit are the same as in the case of the excretion pattern.

Here, the reporting condition according to the excretion pattern and the temperature pattern can be set in consideration of the past urine output of the care receiver and the temperature and humidity at which a cold or the like occurs. This setting is performed, for example, by the administrator operating the display device and the input device of the server 151.
Note that the example of FIG. 11 does not show the excretion pattern according to the excretion amount of stool or the humidity pattern due to the humidity, but basically, it may be defined according to the example of the sensor call condition management table shown in FIG. .

[Sensor information processing operation (Example 1)]
Next, the processing operation of the sensor information will be described with reference to the flowchart in FIG.
The example shown in FIG. 9 is an example in which sensor information is transmitted via Dch of the telephone interface. The Dch is used for transmitting / receiving sensor information, which does not require so much real-time data transmission / reception and has a small amount of data. Here, a diaper sensor worn by a cared person and a body temperature sensor will be described as examples of sensors that do not require so much real-time property and have a small amount of data.

First, sensor information is received from the multifunction telephone IF package 105 (S900). Next, it is determined whether the message is from the Dch-compatible sensor 13 (S901). As a result of this determination, if the message is from the Dch-compatible sensor 13, it is determined whether it is a diaper sensor (S902).
As a result of this determination, if the sensor is a diaper sensor, it is determined whether the sensor ID has already been registered in the sensor information management table (S903).

  If it is not a diaper sensor in the determination of S902, it is determined whether it is a body temperature sensor (S904). As a result of the determination, if it is the body temperature sensor, the processing sequence of the body temperature sensor is performed (S905). On the other hand, if it is determined that the sensor is not the body temperature sensor, error processing is performed with no corresponding sensor (S906). If the sensor information from the body temperature sensor is not collected, the processes of S904 and S905 are unnecessary.

  If it is determined in S901 that the message is not from the Dch-compatible sensor, control of packages other than the sensor, such as voice call using the multifunction telephone IF package 104, is performed (S907).

  Next, in S903, when it is determined that the sensor ID has been registered in the sensor information management table, it is determined whether small excretion is detected by the diaper sensor 1 (S908). As a result, when it is determined that small excretion is detected, small excretion detection processing is performed. Specifically, the PHS of the extension number registered in the sensor call condition management table or the multi-function telephone (MFT) is notified, for example, a predetermined ring tone (for example, melody A) is issued (S9081). Further, the display element 707 of the sensor receiver 12 emits light in the color designated by the sensor call condition management table (S9082). As shown in FIG. 13, if a message is registered in the sensor call condition management table, at the same time as the alarm is issued, a message such as “(User X) Excretion 300 cc or more” is sent to PHS or the like. You can also

Next, when it is determined in S908 that small excretion is not detected, it is determined whether large excretion is detected (S910). As a result, if it is determined that large excretion is detected, large excretion detection processing is performed (S911). Specifically, the PHS of the extension number registered in the sensor call condition management table or the multifunction telephone (MFT) is notified, for example, a predetermined melody B is issued (S9101). Similarly to the above, the display element 707 emits light of the color designated by the sensor call condition management table (S9102). If a message is registered in the sensor call condition management table, a message for detecting large excretion can be sent to PHS or the like at the same time as the notification.
If the sensor information from the sensor that detects stool excretion as the diaper sensor is not collected, the processes of S910, S9101, and S9102 are unnecessary.

  Next, if it is determined in S910 that large excretion is not detected, other detection processing is performed (S915). Specifically, it performs a calling process and a message sending process to a PHS, a multi-function telephone (MFT) and the like.

  Next, when it is determined in S903 that the sensor ID has not been registered, it is determined whether or not the type is the automatic registration type (S913). If the automatic registration type is determined in S913, sensor ID registration processing is performed (S914). On the other hand, if it is determined in S913 that the type is not the automatic registration type, sensor ID non-registration error processing is performed (S915).

  The sensor information (measurement data) detected by the diaper sensor and the body temperature sensor is temporarily stored in the storage unit of the processing device 107, and then used in the statistical processing and analysis process in the processing device 107 or the server 151.

[Sensor information processing operation (Example 2)]
Next, the processing operation of the sensor information will be described with reference to the flowchart in FIG.
The example shown in FIG. 12 is an example in which sensor information is transmitted via Bch of the telephone interface. Bch requires a relatively wide band instead of voice data, and is used for transmitting and receiving sensor information that requires real-time processing. A temperature / humidity sensor will be described as an example of a sensor that requires real-time properties.

  First, sensor information is received from the multifunction telephone IF package 105 (S1200). Next, it is determined whether the message is from the Bch-compatible sensor 13 (S1201). As a result of this determination, if the message is from the Bch-compatible sensor 13, it is determined whether it is a temperature sensor (S1202). If the result of this determination is that it is a temperature sensor, it is determined whether or not that sensor ID has already been registered in the sensor information management table (S1211).

  If it is not a temperature sensor in the determination of S1202, it is determined whether it is a humidity sensor (S1203). If the result of the determination is that it is a humidity sensor, a humidity sensor processing sequence is performed (S1206). On the other hand, if it is determined that the sensor is not the humidity sensor, error processing is performed with no corresponding sensor (S1204). If the sensor information from the humidity sensor is not the target of collection, the processes of S1203 and S1206 are unnecessary.

  If it is determined in S1201 that the message is not from the Bch compatible sensor, packages other than the sensor are controlled, for example, a voice call using the multifunction telephone IF package 104 is performed (S1205).

  Next, in S1211, when it is determined that the sensor ID has been registered in the sensor information management table, it is determined whether a threshold value is detected (S1221). As a result, when it is determined that the threshold value is detected (S1221: Y), it is determined whether the upper limit temperature (the upper limit temperature registered in the sensor call condition management table, for example, 30 ° C.) is detected (S1231). As a result, when it is determined that the upper limit temperature is detected (S1231: Y), the upper limit temperature detection process is performed (S1241). Specifically, the PHS or the multifunction telephone (MFT) of the extension number registered in the sensor call condition management table is notified, for example, a predetermined ring tone (for example, melody B) is issued. Further, the display element 707 of the sensor receiver 12 emits light of a color (for example, red) designated by the sensor call condition management table (S1241). As shown in FIG. 13, if a message is registered in the sensor call condition management table, a message such as "heat index warning" can be sent to PHS or the like at the same time as the notification.

  Next, when it is determined that the upper limit temperature is not detected, it is determined whether the lower limit temperature is detected (S1232). As a result, when it is determined that the lower limit temperature has been detected (S1232: Y), the lower limit detection process is performed (S1242). Specifically, similarly to the above, the PHS or the multifunction telephone (MFT) having the extension number registered in the sensor call condition management table is notified, and the display element 707 is emitted in the designated color.

  Next, when it is determined that the lower limit temperature is not detected (S1232: N), and after the processes of the processes S1241 and S1242, the temperature measurement data included in the sensor information is recorded in the storage unit in the processing device 107 ( S1233). This temperature measurement data is used later in the processing device 107 or the server 151 for statistical and analysis processing.

  Next, when it is determined in S1221 that there is no threshold detection, the temperature measurement data is recorded in the storage unit in the processing device 107 as in the above (S1222).

  Next, if it is determined in S1211 that the sensor ID has not been registered, it is determined whether or not it is an automatic registration type (S1212). As a result, if it is determined that the type is the automatic registration type, registration processing of the sensor ID is performed in the sensor information management table (S1214). On the other hand, if it is determined that the type is not the automatic registration type, sensor ID non-registration error processing is performed (S1213). For example, the fact that an unregistered sensor ID has been found is displayed on the display of the server 151.

  The processing operation of the sensor information has been described above with the first and second examples. In the above description, the example 1 and the example 2 are separately described, but in reality, sensor information acquired by the sensor receiver 12 or the processing device 107 is mixed. To that end, it will be understood that the processing operation of the flowchart is an integration of the processing operations shown in FIGS. 9 and 12.

  As described above, in this embodiment, the sensor receiver is connected to the telephone exchange through the telephone interface. In this case, the multifunctional telephone interface package connected to the telephone interface converts the content of data into the content of transmission / reception of sensor information instead of the content (voice information) of the multifunctional telephone. Further, since the information of the sensor is processed by the processing device in the telephone exchange, the communication information in the telephone exchange is used to transmit and receive the sensor information between the multifunction telephone interface package and the central control unit. As a result, according to the embodiment, it is possible to reduce the construction equipment cost by utilizing the hardware and wiring of the existing telephone exchange. Further, a transmitter / receiver can be connected using the telephone interface of the telephone exchange, and a sensor can be connected to the transmitter / receiver using a general-purpose interface to collect sensor information.

[Other Examples of Sensor Call Condition Management Table]
FIG. 13 shows the structure of a sensor call condition management table according to another embodiment.
Compared to the example shown in FIG. 11, the sensor call condition management table according to another example has a wide variety of processing results (determination contents) by the processing device 107 using sensor information, and is prioritized in 12 steps. . Further, a transmission message is specified as a specific content as a notification content (report), and the display color of the display element 707 of the sensor receiver 12 is increased to 5 colors. In the priority, the reason why the judgment of the sensor information of the temperature and humidity sensor is set higher than that of the diaper sensor is that the temperature and humidity conditions in the living room most affect the health condition of the care recipient (such as catching a cold). This is because the temperature and humidity can be adjusted quickly according to the determination. In addition, the display color of the display element 707 is displayed in the order of red and yellow for the display color having high priority, and attention is given to the care staff.

[Other alternatives and modifications]
The present invention is not limited to the above embodiments, but can be modified in various ways.
For example, in the above-described embodiment, the processing device 107 has various management tables to process sensor information, or a part or all of these processes can be performed by the server 151 or the cloud 152. . In a modified example, part or all of the processing performed by the processing device may be performed by another processor included in the CCU 106 or the PBX 100.

  Further, as another application example, in the above embodiment, the processing of the sensor information is applied to the care system, but it is also applied to the data processing system and the control system for collecting and processing the sensor information in addition to the care system. It is possible.
