Description

  The present invention relates to a telephone exchange system and a data collection method of the telephone exchange system.

  In recent years, there is a telephone exchange system in which a sensor is connected to a telephone exchange and the sensor information output from the sensor is processed by the telephone exchange.

  For example, Patent Document 1 discloses a crime prevention system in which a fire switch or the like for crime prevention is connected to a telephone exchange and the telephone exchange emits an alarm by a speaker or the like when the fire sensor senses.

JP 2004-215047 A

  By the way, the utilization of the sensor in the existing telephone exchange mainly connects the interface of LAN (Local Area Network) to the telephone exchange to exchange information with various sensors, or directly connects the sensor itself to the telephone exchange. There is a way to connect the sensor to a dedicated interface package or an analog line interface package.

  The method of connecting a LAN interface to a telephone exchange to exchange information with various sensors requires installation of a LAN wiring, a hub, etc. separately from the telephone exchange equipment, and thus the introduction cost is high.

  On the other hand, the method of connecting the sensor itself directly to the telephone exchange and connecting the sensor to a dedicated interface package or an analog line interface package is that the information exchange with the sensor is an analog interface and analog binary such as on and off It is an exchange of degrees. Therefore, it is necessary to provide an analog interface on the sensor side too, and a general-purpose sensor can not be used.

  In Patent Document 1, since analog values such as electrostatic capacitance are used via an analog line, it is only possible to exchange on-off and on-off two-level information similar to that of on-hook and off-hook of an analog telephone. Therefore, on the sensor side, it is necessary to provide the same analog interface package as the telephone interface analog interface package. For this reason, it is difficult to connect a general-purpose sensor to a telephone exchange and collect sensor information.

  An object of the present invention is to connect a general-purpose sensor to a telephone exchange to collect sensor information.

  Hereinafter, an embodiment will be described using the drawings.

  The telephone exchange system of the embodiment will be described with reference to FIG. Here, a telephone exchange system installed in an aging facility will be described as an example.

  As shown in FIG. 1, the telephone exchange (private branch exchange: PBX) 100 of the telephone exchange system includes a nurse call interface package (nurse call IF package) 101, an interphone interface package (interphone IF package) 102, and a local PHS master unit interface package. (In-building PHS master unit IF package) 103, multi-function telephone interface package (multi-function telephone IF package) 104, 105, sensor table 106, and central control unit (CCU) 107. Here, the multifunction telephone IF package 104, 105 has a multifunction telephone interface. Here, a multi-functional telephone refers to a telephone connected to a telephone exchange, and in particular to a telephone that enables extension telephones in a private area.

  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 communal 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. In this case, the sensor receiver 119 is connected to the multi setting B of the multifunction telephone 118. The sensor receiver 119 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 119 and normal calling 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. The sensor 121 is connected to the sensor receiver 120. The sensor 121 is, for example, a diaper sensor, a body temperature sensor, an image sensor, or an audio sensor installed in the room 122 of the resident.

  The sensor receiver 120 receives sensor data (sensor information) output from the sensor 121 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 sensor table 106 is a table for storing information on the sensor 121, and exchanges information on the sensor 121 with the central control device 107.

  The central control unit 107 collects and processes sensor data (sensor information) from the sensor receiver 120 or sensor data (sensor information) from the multifunction telephone 118 via the multifunction telephone IF package 105. The central control unit 107 sends the nurse call IF package 101, the interphone IF package 102, the in-building PHS master unit IF package 103, the multi-functional telephone IF package 104, and the multi-functional telephone IF package 105 based on the sensor data processing result. Perform call processing or message transmission processing.

  Specifically, the central control device 107 analyzes sensor information and statistics sensor information by a program of the main body software. The central control unit 107 identifies the nurse call IF package 101, the interphone IF package 102, the in-building PHS master unit IF package 103, and the multi-function telephone IF package 104 based on the analysis result of the sensor information and the information stored in the sensor table 106. And perform processing such as calling and message sending. The central control unit 107 may be connected to an external server 123 or cloud 124 via a LAN, and the server 123 or cloud 124 may perform the analysis and the like.

Next, the communication method of the embodiment 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 in 160 kbps in both directions in full duplex, communication is performed using a method called ping pong transmission on 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 (Transmission and reception of information) is the same as the communication method between the multi-function telephone IF package 104 and the multi-function telephone 116 described above. 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 121 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 121 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 121 in the format as shown in FIG. 3 transmits and receives two channels (64 kbps × 2) via the B channel. In addition, sensor data intermittently output from the sensor 121 transmits and receives 16 kbps via the D channel.

  When the multi-function telephone set 118 to which the sensor receiver 119 is connected is set to receive sensor information, the communication method of the sensor receiver 120 and the multi-function telephone IF package 105 is the same as in the above. Is used. Specifically, the multi-function telephone 118 transmits sensor information constantly output via the sensor receiver 119 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 119 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 include the sensor type, sensor ID (identification number), receiver ID (identification number), priority type, mode, message No. , Sensor data.

Further, 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 107]
The communication system between the multi-function telephone IF package 104 and the central control unit 107 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 (CCU) 107. Central controller 107 sends ANS = 1 to multifunction telephone IF package 104. At this time, the central control unit 107 returns an ACK when there is a buffer empty.

  Next, the multi-function telephone IF package 104 transmits an L / T control packet (SD) to the central control unit 107. The central control unit 107 sends L / T control packet ACK (SDACK), ANS = 0 to the multi-function telephone IF package 104 after normal reception and reception processing is completed.

  The multifunction telephone IF package 105 (L / T # 1) transmits a request (REQ) to the central control unit 107. The central controller 107 does not send back an ACK on no buffer empty. The central control unit 107 sends ANS = 1 to the multi-function telephone IF package 105. The multi-function telephone IF package 105 transmits an L / T control packet (SD) to the central control unit 107. After the central control unit 107 normally receives the L / T control packet (SD) and completes the reception process, it sends the L / T control packet ACK (SDACK), ANS = 0 to the multi-function telephone IF package 105.

  Next, the block configuration of the sensor receivers 119 and 120 will be described with reference to FIG.

  The microcomputer 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, as the interface (IF), if wired, LAN, USB or the like is used, and if wireless, Bluetooth (registered trademark) or the like is used. A sensor 121 (see FIG. 1) is connected to the sensor IF module 701.

  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. Further, to the I / O, a multi-connection switching switch (SW) 706 and an LED 707 for displaying a state or a fault are connected. 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).

  Thus, the sensor receivers 119, 120 have 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, data is transmitted and received between the sensor receivers 119 and 120 and the multi-function telephone IF package 105 using the sensor information instead of the voice information of the multi-function telephone 116.

  At this time, the B channel (Bch) is used for transmission and reception of sensor information (sensor information constantly generated) which requires a relatively wide band instead of voice information and requires real time property. And D channel (Dch) is used for transmission and reception of sensor information (sensor information generated intermittently) with little real-time property required for data transmission and reception and a small amount of data.

  Next, the procedure of data transmission and reception using D channel (Dch) performed by the central control unit 107 will be described with reference to the flowchart of FIG.

  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, a diaper sensor and a body temperature sensor will be described as an example of a sensor that does not require much real-time performance and has a small amount of data.

First, data (Dch) is received from the multi-function telephone IF package 105 (S800).
Next, it is determined whether the message is from the sensor 121 for Dch (S801).
Next, if it is a message from the sensor 121 for Dch, it is determined whether it is a diaper sensor (S802).

Next, if it is a diaper sensor, it is judged whether sensor ID registration is completed (S803).
Next, if it is not a diaper sensor, it is determined whether it is a temperature sensor (S804).
Next, if it is determined that the sensor is a body temperature sensor, a processing sequence of the body temperature sensor is performed (S805).
Next, if it is determined that the sensor is not the body temperature sensor, error processing without the corresponding sensor is performed (S806).

  Next, in S810, when it is determined that the message is not a message from a Dch-compatible sensor, control of packages other than the sensor is performed (S807).

Next, if it is determined in S803 that the sensor ID has been registered, it is determined whether small excretion is detected (S808).
Next, when it is determined that the small excretion is detected, the small excretion detection process is performed (S809). Specifically, call processing and message transmission processing of PHS and multi-function telephone (MFT) of the corresponding group are performed. The message is, for example, a message of “(user) small excretion detection”.

Next, if it is determined in S808 that small excretion is not detected, it is determined whether large excretion is detected (S810).
Next, when it is determined that the large excretion is detected, the large excretion detection processing is performed (S811). Specifically, call processing and message transmission processing of PHS and multi-function telephone (MFT) of the corresponding group are performed. The message is, for example, a message of “(user) large excretion detection”.

  Next, when it is determined in S810 that the large excretion is not detected, other detection processing is performed (S812). Specifically, call processing and message transmission processing of PHS and multi-function telephone (MFT) of the corresponding group are performed. The message sends out the sending message from the sensor 121 as it is.

Next, if it is determined in S803 that the sensor ID has not been registered, it is determined whether it is an automatic registration type (S813).
Next, when it is determined in S813 that the type is the automatic registration type, sensor ID registration processing is performed (S814).
Next, when it is determined in S813 that the type is not the automatic registration type, a sensor ID non-registration error process is performed (S815).

  Here, the central control unit 107 performs data transmission / reception using Dch with reference to the diaper sensor table shown in FIG. 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, a diaper sensor will be described as an example of a sensor that does not require much real time performance and has a small amount of data.

The contents of the diaper sensor table will be described with reference to FIG.
The diaper sensor table is stored in a sensor table 106 in the telephone exchange 100 (see FIG. 1). As shown in FIG. 9, in the diaper sensor table, a sensor receiver ID, a sensor ID registration type, a sensor ID, a user, a small excretion call group (G), and a large excretion call group (G) are registered respectively. There is. For example, in the sensor receiver ID7, the sensor ID registration type is automatic, the sensor ID is ABC100, the user is Mr. A, the small excretion call G is 1, and the large excretion call G is 1 It is.

Next, the contents of the small excretion setting table will be described with reference to FIG.
The small excretion setting table is stored in the sensor table 106 in the telephone exchange 100 (see FIG. 1). As shown in FIG. 10, in the small excretion setting table, a call G number, a call extension, and a message are registered. For example, when the call G number is 1, the call extensions are 2000, 3000, 3001, 3002 and 3003, and the message is "small excretion detected".

  The central control unit 107 refers to the diaper sensor table of FIG. 9 and the small excretion setting table of FIG. 10, and when the diaper sensor of the corresponding sensor ID detects small excretion, the user performs small excretion The small excretory call G is sent a message "small excrement detected" via the call extension.

  Next, the procedure of data transmission and reception using Bch performed by the central control unit 107 will be described with reference to the flowchart of FIG. 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 sensor will be described as an example of a sensor that requires real-time capability.

  First, data (Bch) is received from the multi-function telephone IF package (DLIN) 105 (S1100).

Next, it is determined whether the message is from the Bch compatible sensor (S1110).
Next, if it is a message from the Bch corresponding sensor, it is determined whether it is a temperature sensor (S1120).

Next, if the sensor is a temperature sensor, it is determined whether the sensor ID has been registered (S1130).
Next, if it is not a temperature sensor, it is judged whether it is a humidity sensor (S1140).

Next, if it is determined that the sensor is a humidity sensor, the processing sequence of the humidity sensor is performed (S1150).
Next, when it is determined in S1140 that the sensor is not the humidity sensor, error processing without the corresponding sensor is performed (S1160).
Next, when it is determined in S1110 that the message is not a message from the Bch compatible sensor, control of packages other than the sensor is performed (S1170).

Next, if it is determined that the sensor ID has been registered in S1130, it is determined whether or not there is a threshold detection (S1180).
Next, if it is determined that the threshold is detected, it is determined whether the upper limit is detected (S1190).
Next, when it is determined that upper limit detection is to be performed, upper limit detection processing is performed (S1200). Specifically, call processing and message transmission processing of PHS and multi-function telephone (MFT) of the corresponding group are performed. The message is, for example, a message of “(installation point) high temperature detection”.

Next, when it is determined that the upper limit detection is not performed, it is determined whether the lower limit detection is performed (S1210).
Next, when it is determined that the lower limit detection is performed, the lower limit detection processing is performed (S1220). Specifically, call processing and message transmission processing of PHS and multi-function telephone (MFT) of the corresponding group are performed. The message is, for example, a message of “(installation point) low temperature detection”.

  Next, when it is determined that the lower limit detection is not performed, the temperature measurement data is stored in the central control unit 107 or the server 123 and used for statistical and analysis processing (S1230).

  Next, when it is determined in S1180 that the threshold detection is not present, the temperature measurement data is stored in the central control unit 107 or the server 123 and used for the statistics and analysis processing (S1240).

Next, when it is determined in S1130 that the sensor ID has not been registered, it is determined whether it is an automatic registration type (S1250).
Next, when it is determined that the type is an automatic registration type, a sensor ID registration process is performed (S1260).
Next, when it is determined that the type is not the automatic registration type, a sensor ID non-registration error process is performed (S1270).

The contents of the temperature sensor table will be described with reference to FIG.
The temperature sensor table is stored in a sensor table 106 in the telephone exchange 100 (see FIG. 1). As shown in FIG. 12, in the temperature sensor table, a sensor receiver ID, a sensor ID registration type, a sensor ID, an installation place, and a management G are registered. For example, in the sensor receiver ID1, the sensor ID registration type is automatic, the sensor ID is DEF100, the installation location is a room A, and the management G is 1. Further, in the sensor receiver ID3, the sensor ID registration type is manual, the sensor ID is DEF102, the installation location is an office, and the management G is 3.

Next, the contents of the temperature sensor management table will be described with reference to FIG.
The temperature sensor management table is stored in a sensor table 106 in the telephone exchange 100 (see FIG. 1).
As shown in FIG. 13, in the temperature sensor management table, a management G number, presence / absence of threshold detection, a threshold upper limit, a threshold lower limit, a call extension, and a message are registered. For example, when the call G number is 1, the threshold detection is present, the threshold upper limit is 30, the threshold lower limit is 10, the call extensions are 2000, 3000, 3001, 3002, 3003, and the message is It is "room temperature abnormality detection".

  The central control unit 107 refers to the temperature sensor table of FIG. 12 and the temperature sensor management table of FIG. 13 and, when the temperature sensor of the corresponding sensor ID detects the threshold upper limit or the threshold lower limit, In response, the message "room temperature error detection" is sent.

  Thus, in one embodiment, a multi-functional telephone interface package is used to connect the sensor receiver to the telephone switch. At this time, although the interface of the multifunction telephone is used, the content of the data is converted to the content of transmission / reception of sensor information instead of the content of the multifunction telephone. Also, in order to process sensor information by the central control unit of the telephone exchange, sensor information is transmitted and received between the multi-function telephone interface package and the central control using a 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. In addition, general-purpose sensors can be connected to the telephone exchange to collect sensor information.
