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 the condition of a cared person etc. in the care system with a sensor and reports according to the detected sensor information. It relates to the collection and processing of information.

  As an important treatment in a nursing home, there is a work of changing the diaper of the care recipient. Conventionally, a carer (sometimes referred to as a care staff) visits the room of the care recipient in response to a call (nurse call) by the operation of the push button switch of the care recipient, and confirms the condition of the diaper or periodically The method was to take a round trip and check.

  Recently, in order to reduce the burden on the carer and replace the diaper at the optimal timing when the care recipient had excreted, the urination sensor is used to detect urination and a management computer (or personal computer (PC)) However, there is known a system for reporting urination detection to a portable terminal carried by a caregiver (see Patent Documents 1 and 2).

  According to the care system described in Patent Literatures 1 and 2, voice information and character information are transmitted from the management computer to the portable terminal possessed by the caregiver, and voice output and character display are performed on the portable terminal. Or it is displayed on the display of a personal computer. However, when the portable terminal receives a message, the carer may be blocking the hand because the carer is under treatment, and it may not be possible to immediately cope with the portable terminal. Also, the display of personal computers is generally viewed by the administrator, and not all caregivers will see each time. Furthermore, since the message is usually notified when the management computer determines that the diaper has been replaced, the caregiver does not know the condition of the care recipient's diaper except at that time. Therefore, it is convenient for a care facility or a caregiver if it is possible to constantly visualize the condition of the care recipient detected by a urine sensor or the like.

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

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A care system according to one embodiment will be described with reference to FIG. The care system is realized by applying a sensor information processing system or a sensor information processing method to a care facility.

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

  The nurse call IF package 101 is connected to the server 109 disposed in the nurse call system 108. The server 109 is connected to the microphone / speaker with handgrip button 110 to receive a nurse call. The intercom IF package 102 is connected to the embedded intercom 112 disposed in the staff call system 111. The in-building PHS base unit 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 disposed in the office 115.

  The multi-function telephone IF package 105 is connected to a multi-function telephone 118 installed in a common facility 117 such as a dining room or a rest area. The multifunction telephone 118 has a configuration (multi setting A, multi setting B) capable of multi connection. For example, the sensor receiver 121 is connected to the multi setting B of the multifunction 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, reception of sensor information from the sensor receiver 121 and normal communication can be performed according to the setting.

  Further, the sensor receiver 120 is directly connected to the multi-function 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 generally referred to as the sensor receiver 12.

  The 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 attached to the care recipient, a temperature and humidity sensor installed in the room 14 of the resident, an image sensor for detecting the motion of the care recipient, an audio sensor for detecting the voice of the care recipient, a door of the living room There are an open / close sensor, a body temperature sensor that detects the body temperature of the care recipient, and the like. There are two types of diaper sensors: urine sensors and stool sensors.

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

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

  The central control unit 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 unit 107 and processed there. Based on the processing result of the sensor information by the processing unit 107, the central control unit 106 transmits the nurse call IF package 101, the interphone IF package 102, the in-building PHS master unit IF package 103, the multi-function telephone IF package 104, and the multi-function telephone IF package. A call processing or message transmission processing is performed on 105.

  More specifically, the processing unit of the processing device 107 executes an application program and analyzes sensor information and statistics sensor information while referring to the sensor information management table and the sensor call condition management table. The central control unit 106 uses the nurse call IF package 101, the interphone IF package 102, the in-building PHS parent machine IF package 103, based on the processing result of the sensor information by the processing unit 107 and the information managed in the sensor call condition management table. The multi function telephone IF package 104 is specified, and processing such as notification or message transmission is performed. Also, control information for displaying the display element 707 is transmitted from the multi-function telephone IF package 105 to the sensor receiver 120 via the telephone interface.

  The central control unit 106 can be connected to an external server 151 or the cloud 152 via a LAN. For example, the processing device 107 can be connected to the server 151 or the cloud 152 via the LAN, and the server 151 or the cloud 152 can perform part or all of the processing such as the analysis performed by the processing device 107. As described above, when the processing device 107 performs processing, the content of the management table of the processing device 107 is rewritten or various instructions are performed using an input device or a display (not shown) of the server 151. You can enter

Next, a communication method 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 telephone call is performed with an interface capable of transmitting and receiving data such as normal incoming / outgoing calls, button control, LCD control, and telephone directory control. Use voice communication interface for.

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

  Normally, the multi-function telephone 116 transmits voice information (voice data (PCM: Pulse Code Modulation)) to the multi-function telephone interface package 104 using the B channel as the multi-function telephone interface. Also, the multi-function telephone set 116 transmits control information (control data such as an LCD) to the multi-function telephone interface package 104 using the D channel as a multi-function telephone 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 AMI (Alternate Mark Inversion) coding. The AMI coding scheme is one of coding schemes used for digital communication, and is a scheme in which positive and negative polarity codes are alternately sent out each time "1" is generated.

Here, the ping-pong transmission method is the following method.
Generally, two 64 kbps B-channels and one 16 kbps D-channel are supported in ISDN (Integrated Service Digital Network), but adding a control signal to this requires a total transmission speed of 160 kbps. Since the telephone station and the subscriber's home must transmit data at 160 kbps bi-directionally in full duplex, communication is performed using a method called ping pong transmission over a pair of copper wires. In this method, the transmission bit rate is speeded up to approximately 320 kbps (time base compression) to enable transmission in half time, and data is sent alternately from the central office and the subscriber home. To be precise, it is called time-division control transmission method (TCM: Time Compress Multiplexing).

  In FIG. 2, F is a start bit (frame synchronization) and 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 of an LCD or the like. P is parity (even).

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

  Note that the communication method between the multi-function telephone IF package 105 and the multi-function telephone 118 has a configuration (multi setting A, multi setting B) with which the multi-function telephone 118 can be multi-connected, so it can The transmission and reception of information is the same as the communication method between the multifunction telephone IF package 104 and the multifunction telephone 116. On the other hand, when the multi-function telephone set 118 is set to receive sensor information, the same communication method as the communication method of the sensor receiver 120 and the multi-function telephone IF package 105 described below is used.

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

  The sensor receiver 120 transmits sensor information constantly output from the sensor 13 to the multi-function telephone IF package 105 using the B channel as an interface for the multi-function telephone. Also, the sensor receiver 120 transmits sensor information intermittently output from the sensor 13 to the multi-function telephone IF package 105 using the D channel as a multi-function telephone interface.

  Specifically, the B channel is used for transmitting and receiving sensor information (sensor information that is constantly generated) that requires relatively a band instead of voice information and requires real-time capability. Then, the D channel is used to transmit and receive sensor information (intermittently generated sensor information) with less real time required for data transmission and reception and a small amount of data.

  In FIG. 3, F is a start bit (frame synchronization), and 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 parity (even).

  Sensor data constantly output from the sensor 13 in the format as shown in FIG. 3 performs transmission and reception of two channels (64 kbps × 2) via the B channel. Also, sensor data intermittently output from the sensor 13 performs transmission and reception of 16 kbps via the D channel.

  When the multi-function telephone set 118 to which the sensor receiver 121 is connected is set to receive sensor information, the communication method similar to that of the sensor receiver 120 and the multi-function telephone IF package 105 is used. A communication scheme is used. Specifically, the multi-function telephone 118 transmits sensor information constantly output via the sensor receiver 121 to the multi-function telephone IF package 105 using the B channel as an interface for the multi-function telephone. Also, the multi-functional telephone 118 transmits sensor information intermittently output via the sensor receiver 121 to the multi-functional telephone IF package 105 using the D channel as the multi-functional telephone interface.

Here, FIG. 4 shows an example of contents of D channel (Dch) for sensor.
As shown in FIG. 4, the contents of the sensor Dch are the sensor type, sensor ID (identification number), receiver ID (identification number), priority type, mode, message No, and sensor data.

FIG. 5 shows an example of contents of a B channel (Bch) for a sensor.
As shown in FIG. 5, the contents of the sensor Bch are: 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 multifunction telephone IF packages 104 and 105 and central control unit 106]
The communication system between the multifunction telephone IF package 104 and the central control unit 106 is a communication system in the telephone exchange 100, and it is necessary to reliably communicate a predetermined band without delay. For this reason, there is a need for a system that ensures a fixed bandwidth.

  In addition, since control communication is irregular and the amount of communication also changes, a communication scheme close to request, answer and packet transmission is adopted. As shown in FIG. 6, frame transmission / reception for link access of D channel is performed by a procedure by soft 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 control unit 106. Central controller 106 sends ANS = 1 to multifunction telephone IF package 104. At this time, the central control unit 106 returns ACK with buffer empty.

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

  The multi-function telephone IF package 105 (L / T # 1) transmits a request (REQ) to the central control unit 106. The central controller 106 does not send back an ACK on no buffer empty. Central controller 106 sends ANS = 1 to multifunction telephone IF package 105. The multi-function telephone IF package 105 transmits an L / T control packet (SD) to the central control unit 106. After the central control unit 106 normally receives the L / T control packet (SD) and completes the reception process, it sends an L / T control packet ACK (SDACK), ANS = 0 to the multi-function telephone IF package 105.

[Configuration of sensor receiver 12]
Next, the block configuration of the sensor receiver 12 will be described with reference to FIG.
The microprocessor 700 has a universal asynchronous receiver transmitter (UART), an interface (IF) for sensors such as USB and LAN, an I / O, a serial IF, and a bus. A sensor IF module 701 is connected to the sensor IF. Here, the sensor IF is a general-purpose interface, and if wired, LAN, USB or the like 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 through the sensor IF 701 or other interface, control information transmitted from the central control unit 106, and control information transmitted from the CCU 106. The element 707 (display unit) is subjected to display control (emission control).

  A contact drive circuit 702 is connected to the I / O, and a contact connector 703 is connected to the contact drive circuit 702 to be a contact output. Further, 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 to be a contact input. Here, the contact connector 705 is, for example, a terminal for receiving sensor information of a door sensor that detects the opening and closing of the door of the living room, and the contact connector 703 is a terminal for transmitting a control signal for automatically locking the door of the living room.

Also connected to the I / O is a multi-connection switching switch (SW) 706 and a display element 707 for displaying the state of the diaper of the care receiver detected by the sensor, such as 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 emits 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 recipient and the degree of danger due to the temperature and humidity of the living room by visually observing the emitted color. In other words, the display unit realizes "visualization" of sensor information in a care facility. (This will be discussed in more 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 RJ 11 modular connector 713. The RJ11 modular connector 713 is connected to a multi-function telephone IF package (DLIN) 105. Also, an RJ11 modular connector 714 is connected to the noise filter 712. The RJ11 modular connector 714 is multi-connected to the multifunction 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 the serial interface (IF) and the ping-pong transmission / reception interface (IF) circuit 710 via the B channel (Bch: 64 Kbps) and the D channel (Dch: 16 Kbps), the multifunctional telephone An interface 750 (portion surrounded by a dotted line in FIG. 7) is configured. At this time, transmission / reception of sensor information is performed between the sensor receivers 121 and 120 and the multifunction telephone IF package 105 instead of the voice information of the multifunction telephone 116.

Here, the B channel (Bch) is used to transmit and receive sensor information (sensor information that is constantly generated) that requires a relatively wide band instead of voice information and requires real-time capability. On the other hand, the D channel (Dch) is used to transmit and receive sensor information (sensor information generated intermittently) with less real-time property required for data transmission and reception and a small amount of data.
Although the sensor receiver 12 is referred to in this embodiment, it may be referred to as a transmitter / receiver because it transmits and receives sensor information and control information.

The appearance of the sensor receiver 12 is shown in FIG.
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 has three domes integrally formed on a dome-shaped upper case 121 made of polocarbonate (PC), a bottom cover 122 for mounting components of the sensor receiver, and the bottom cover 122. It comprises leg 123 and bottom lid convex part 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 lid 122 is provided with three legs 123, the case of the sensor receiver 12 can be placed on a table such as the room of the care recipient. Further, by providing hooks (not shown) such as holes and fittings in the bottom lid convex part 124, the case can be locked to hook fittings and the like provided in the room of the care recipient and the outer wall thereof. If the sensor receiver 12 is installed in the living room or its outer wall, the care staff only sees the color displayed by the display element 707 of the sensor receiver 12 and the condition of the care receiver's diaper in the living room or The temperature state of the room can be easily recognized. Thereby, "visualization" of sensor information in a nursing home can be realized.

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

  The sensor information management table shown in FIG. 10A shows a sensor ID for identifying the sensor, a sensor type for indicating the sensor type, a user ID for indicating the user of the sensor (caregee), and a condition of the sensor call. Register patterns such as excretion patterns and temperature patterns. The contents of the sensor call condition management table are indexed by the above pattern indicating the sensor call condition. Here, since the temperature sensor is not directly attached to the user but installed in the room where the user is located, the place ID for identifying the room may be registered in the "user" column.

  The receiver management table shown in FIG. 10B manages the sensor ID to be received by the sensor receiver 12 and indicates the receiver ID for identifying the sensor receiver and the installation location of the sensor receiver. Register the receiver name and the sensor ID to be received. When the sensor attached to the care recipient or the sensor installed in the living room increases or decreases, the registration of the sensor ID to be received increases or decreases accordingly.

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

  Each of the sensor call condition management tables shown in FIGS. 11A and 11B is a pattern ID for identifying a pattern, a time zone for performing a treatment such as an alert, a notification indicating an alert condition, and an alert time. The time, the extension number of the notification destination telephone, the display color displayed by the display element 707 provided in the receiver 12, the ringing tone indicating the type of the extension telephone's melody, and the like are registered. The display element 707 displays the designated color for the notification time. In the example of FIG. 11 (A), the alerting conditions are different between the excretion patterns 1 and 2. This is because the amount of urination detected by the urine sensor differs depending on the cared person, so that the notification condition is changed according to the amount of urination detected by the urine sensor. For example, at the time of the first urination, there is little urination volume and replacement of the diaper is unnecessary, so notification time of notification is as short as 1 minute, but diaper replacement is necessary when the urination volume becomes more than the specified amount. The notification time of 5 minutes is extended to 5 minutes, and the color of the display element 707 also changes to red. The care staff senses the change in the melody that the telephone held by the user has arrived and / or the change in the display color of the display element 707, and carries out the diaper replacement process.

  In the example of the temperature pattern shown in FIG. 11B, when the temperature of the living room detected by the temperature and humidity sensor is 20 to 28 degrees C, no alarm is issued, but an alarm is issued if the temperature is above or below the range. Since temperature and humidity management of the living room largely affects the health condition of the care recipient (for example, the occurrence of a cold etc.), the notification conditions are made different according to the minute change of the temperature. The notification time of the alert, the ring tone, and the display color of the display unit are the same as in the case of the excretion pattern.

Here, the notification condition according to the excretion pattern and the temperature pattern can be set in consideration of the amount of voided urine of the care recipient in the past 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 and the input device of the server 151.
In addition, although the excretion pattern by the excretion amount of stool and the humidity pattern by humidity are not shown in the example of FIG. 11, it may be basically defined according to the example of the sensor call condition management table shown in FIG. .

[Processing Process of Sensor Information (Example 1)]
Next, the processing operation of sensor information will be described with reference to the flowchart of FIG.
The example shown in FIG. 9 is an example in which sensor information is transmitted via Dch of the telephone interface. Dch is used to transmit and receive sensor information with less real-time capability for data transmission and reception and a small amount of data. Here, as a sensor that does not require much real-time performance and has a small amount of data, a diaper sensor and a temperature sensor attached to a care recipient will be described as an example.

First, sensor information is received from the multi-function telephone IF package 105 (S900). Next, it is determined whether the message is from the sensor 13 compatible with Dch (S901). If it is a message from the sensor 13 corresponding to Dch as a result of this judgment, it is judged whether it is a diaper sensor (S902).
If it is a diaper sensor as a result of this judgment, it will be judged whether the sensor ID has been registered in the sensor information management table (S903).

  If it is not a diaper sensor in judgment of S902, it will be judged whether it is a body temperature sensor (S904). If it is the body temperature sensor as a result of the judgment, 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 without the corresponding sensor (S906). When the sensor information from the body temperature sensor is not targeted for collection, the processes of S904 and S905 are unnecessary.

  If it is determined in S901 that the message is not a message from a Dch-compatible sensor, control of a package other than the sensor, for example, a voice call using the multi-function telephone IF package 104 is performed (S907).

  Next, in S903, if it is determined that the sensor ID has been registered in the sensor information management table, it is determined whether the small excretion is detected by the diaper sensor 1 (S908). As a result, when it is determined to be small excretion detection, small excretion detection processing is performed. Specifically, an alarm is issued to the PHS or multifunction telephone (MFT) of the extension number registered in the sensor call condition management table, for example, with a predetermined ringtone (for example, melody A) (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). In addition, as shown in FIG. 13, if a message is registered in the sensor call condition management table, a message such as "(user X Mr. Excretion 300 cc or more)" is sent to PHS etc. simultaneously with notification. It can also be done.

Next, when it is determined in S 908 that the small excretion is not detected, it is determined whether the large excretion is detected (S 910). As a result, when it is determined that the large excretion is detected, the large excretion detection processing is performed (S911). Specifically, the PHS or the multi-function telephone (MFT) of the extension number registered in the sensor call condition management table is notified, for example, by a predetermined melody B (S9101). Similarly to the above, the display element 707 emits light in the color designated by the sensor call condition management table (S9102). If a message is registered in the sensor call condition management table, it is possible to transmit a large excretion detection message to the PHS or the like simultaneously with the notification.
In addition, when sensor information from a sensor that detects stool excretion as a diaper sensor is not a target of collection, the processes of S910, S9101, and S9102 are unnecessary.

  Next, when it is determined in S910 that the large excretion is not detected, other detection processing is performed (S915). Specifically, call processing and message transmission processing to a PHS, a multifunction telephone (MFT) or the like are performed.

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

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

[Process operation of sensor information (example 2)]
Next, the processing operation of the sensor information will be described with reference to the flowchart of FIG.
The example shown in FIG. 12 is an example of transmitting sensor information via Bch of the telephone interface. Bch requires relatively a bandwidth instead of voice data, and is used to transmit and receive sensor information that requires real-time capability. A temperature and humidity sensor will be described as an example of a sensor that requires real-time performance.

  First, sensor information is received from the multi-function telephone IF package 105 (S1200). Next, it is determined whether the message is from the sensor 13 for Bch (S1201). As a result of this determination, if it is a message from the sensor 13 corresponding to Bch, it is determined whether it is a temperature sensor (S1202). If the result of this determination is that the sensor is a temperature sensor, it is determined whether the sensor ID has 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). As a result of the judgment, if it is the humidity sensor, the processing sequence of the humidity sensor is performed (S1206). On the other hand, if it is determined that the sensor is not the humidity sensor, error processing is performed without the corresponding sensor (S1204). When the sensor information from the humidity sensor is not to be collected, the processes of S1203 and S1206 are unnecessary.

  If it is determined in S1201 that the message is not a message from a Bch-compatible sensor, control of a package other than the sensor, for example, a voice call using the multi-function 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 threshold detection is present (S1221). As a result, when it is determined that the threshold is detected (S1221: Y), it is determined whether the upper limit temperature (the upper limit temperature registered in the sensor call condition management table, eg, 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 ringing tone (for example, melody B). Furthermore, the display element 707 of the sensor receiver 12 emits light in a color (for example, red) specified in the sensor call condition management table (S1241). As shown in FIG. 13, if a message is registered in the sensor call condition management table, it is possible to transmit a message, for example, "Heatness Index Caution", to the PHS etc. simultaneously with notification.

  Next, when it is determined that the upper limit temperature detection is not performed, it is determined whether the lower limit temperature detection is performed (S1232). As a result, when it is determined that the lower limit temperature is detected (S1232: Y), the lower limit detection processing is performed (S1242). Specifically, in the same manner as described above, the PHS or the multifunction telephone (MFT) of the extension number registered in the sensor call condition management table is notified, and the display element 707 emits light in the designated color.

  Next, when it is determined that the lower limit temperature detection is not performed (S1232: N), and after the above-described 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 later used for statistical and analysis processing in the processing device 107 or the server 151.

  Next, when it is determined that the threshold is not detected in S1221, the temperature measurement data is recorded in the storage unit in the processing device 107 in the same manner as described above (S1222).

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

  In the above, processing operation of sensor information was explained by Example 1 and Example 2. Although the above description is divided into Example 1 and Example 2, in actuality, the sensor information acquired by the sensor receiver 12 to the processing device 107 coexist. It will be understood that for that purpose, it becomes a processing operation of a flowchart which integrates the processing operation shown in FIG. 9 and FIG.

  As mentioned above, in this embodiment, the sensor receiver is connected to the telephone exchange via the telephone interface. In this case, the multi-function telephone interface package connected to the telephone interface converts the contents of the data into the contents of transmission / reception of sensor information, not the contents (voice information) of the multi-function telephone. Further, since the sensor information is processed by the processing unit in the telephone exchange, the sensor information is transmitted and received between the multi-function telephone interface package and the central control unit using the communication system in the telephone exchange. Thus, according to the embodiment, it is possible to reduce the cost of construction equipment by using the hardware and wiring of the existing telephone exchange. Furthermore, a transceiver interface can be used to connect a transceiver using a telephone interface, and sensors can be connected to the transceiver using a general-purpose interface to collect sensor information.

[Another Embodiment of Sensor Call Condition Management Table]
FIG. 13 shows the configuration of a sensor call condition management table according to another embodiment.
Compared with the example shown in FIG. 11, in the sensor call condition management table according to the other example, the processing result (determination content) by the processing device 107 using the sensor information is diversified and prioritized in 12 steps. . Furthermore, the transmission message is defined by specific words as the notification content (report), and the display color of the display element 707 of the sensor receiver 12 is also increased to five. The reason for making the priority of judgment by the sensor information of the temperature and humidity sensor higher than that of the diaper sensor in the priority is that the temperature and humidity of the living room most affect the health condition of the care recipient (such as catching a cold). This is to quickly adjust the temperature and humidity according to the determination. Further, the display color of the display element 707 is also displayed in red and yellow in the order of high priority to take care so as to draw attention of the care staff.

[Other alternatives, variations]
The present invention is not limited to the above embodiments, and can be implemented with various modifications.

In a variation, part or all of the processing performed by the processing device may be performed by the CCU 106 or another processor included in the PBX 100.

  As another application example, in the above embodiment, the processing of sensor information is applied to a care system, but it is also applied to a data processing system or control system that collects and processes sensor information in addition to a care system. It is possible.
