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 analog line interface package is an analog interface for exchanging information with the sensor, and has two analog values such as on and off. It exchanges degrees. Therefore, it is necessary to provide an analog interface on the sensor side as well, and a general-purpose sensor cannot be used.

Since Patent Document 1 uses analog values such as capacitance via an analog line, it can only exchange information of about two values of on and off, which is the same as on-hook and off-hook of an analog telephone. Therefore, it is necessary to provide the same analog interface package as the analog interface package of the telephone exchange on the sensor side. Therefore, it is difficult to connect a general-purpose sensor to a telephone exchange and collect sensor information.

It has a (private branch exchange IF package) 103, a multi-function telephone interface package (multi-function telephone IF package) 104, 105, a sensor table 106, and a central control device (CCU) 107. Here, the multifunction telephone IF packages 104 and 105 have a multifunction telephone interface. Here, the multifunctional telephone is a telephone connected to a telephone exchange, and in particular, a telephone that enables an extension telephone on the 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 located in the staff call system 111. The premises PHS master 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 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 multifunctional telephone interface as the multifunctional telephone interface of the multifunctional telephone IF package 105. Here, since the multifunctional telephone 118 has a configuration capable of multi-connection, it is possible to receive sensor information from the sensor receiver 119 and perform 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 multifunctional telephone interface as the multifunctional telephone interface of the multifunctional telephone IF package 105. A sensor 121 is connected to the sensor receiver 120. The sensor 121 is a diaper sensor, a body temperature sensor, an image sensor, a voice sensor, or the like installed in the resident's room 122.

The sensor receiver 120 receives the sensor data (sensor information) output by the sensor 121 via the general-purpose interface. Here, as the general-purpose interface, LAN, USB (Universal Serial Bus) or the like is used if it is wired, and Wifi (registered trademark), Bluetooth (registered trademark) or the like is used if it is wireless.

The sensor table 106 is a table for storing information about the sensor 121, and exchanges information about the sensor 121 with the central control device 107.

Next, the communication method of the embodiment will be described.
Regarding the communication method, as the minimum required functions as an interface of the multifunction telephones 116 and 118, a call is made with an interface capable of transmitting and receiving data such as normal incoming / outgoing calls, button control, LCD control, and telephone directory control. Use the voice communication interface for.

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

Normally, the multifunction telephone 116 uses the B channel as the multifunction telephone interface to transmit voice information (voice data (PCM: Pulse Code Modulation)) to the multifunction telephone interface package 104. Further, the multifunction telephone 116 uses the D channel as the multifunction telephone interface to transmit control information (control data such as LCD) to the multifunction telephone interface package 104.

The communication method between the multifunction telephone IF package 104 and the multifunction telephone 116 is a general ping-pong transmission method. The mounting line uses the AMI (Alternate Mark Innovation) coding method. The AMI coding method is one of the coding methods used for digital communication, and is a method in which positive and negative polar codes are alternately transmitted each time "1" is generated.

Here, the ping-pong transmission method is the following method.
Generally, ISDN (Integrated Services Digital Network) supports two 64 kbps B channels and one 16 kbps D channel, but when a control signal is added to this, a total transmission speed of 160 kbps is required. Since it is necessary to transmit 160 kbps data in both directions in full duplex between the telephone office and the subscriber's house, communication is performed on a pair of copper wires using a method called ping-pong transmission. In this method, the transmission bit rate is doubled to 320 kbps (time axis compression) so that the data can be transmitted in half the time, and the data is transmitted alternately from the telephone office 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) and is always “00”. B1 is a B1 channel (64 kbps), and audio data (PCM) is transmitted via the B1 channel. B2 is a B2 channel (64 kbps), and audio 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 number).

In the format shown in FIG. 2, audio data is transmitted and received for two channels (64 kbps x 2) via the B channel. Further, 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 (multi-setting A, multi-setting B) in which the multi-function telephone 118 can be multi-connected, so that a call (voice) can be made. Information transmission / reception) 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 multifunction telephone 118 is set to receive the sensor information, the same communication method as the communication method between the sensor receiver 120 and the multifunction telephone IF package 105 described below is used.

[Communication method between sensor receiver 120 and multifunction telephone IF package 105]
A communication method between the sensor receiver 120 and the multifunction telephone IF package 105 will be described with reference to FIG.

Data is transmitted / received 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 the sensor information instead of the voice information of the multifunction telephone 116. ..

The sensor receiver 120 uses the B channel as an interface for the multifunction telephone, and transmits the sensor information constantly output from the sensor 121 to the multifunction telephone IF package 105. Further, the sensor receiver 120 uses the D channel as the multifunction telephone interface to transmit the sensor information intermittently output from the sensor 121 to the multifunction telephone IF package 105.

Specifically, the B channel is used for transmitting and receiving sensor information (sensor information that always occurs) that requires a relatively large band instead of voice information and requires real-time performance. Then, the D channel is used for transmission / reception of sensor information (sensor information that occurs intermittently) in which real-time performance is not required so much for data transmission / reception and the amount of data is small.

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 number).

In the format shown in FIG. 3, the sensor data constantly output from the sensor 121 is transmitted and received for two channels (64 kbps × 2) via the B channel. Further, the sensor data intermittently output from the sensor 121 is transmitted and received at 16 kbps via the D channel.

Regarding the multifunctional telephone 118 to which the sensor receiver 119 is connected, if it is set to receive the sensor information, it is the same as the communication method between the sensor receiver 120 and the multifunctional telephone IF package 105. Communication method is used. Specifically, the multifunction telephone 118 uses the B channel as an interface for the multifunction telephone, and transmits sensor information constantly output via the sensor receiver 119 to the multifunction telephone IF package 105. Further, the multifunction telephone 118 uses the D channel as the multifunction telephone interface to transmit the sensor information intermittently output via the sensor receiver 119 to the multifunction telephone IF package 105.

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

Further, 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 sensor Bch include start frame, sensor type, sensor ID (identification number), receiver ID (identification number), priority type, mode, BCC, end frame, and sensor data (video, Voice, temperature, etc.).

[Communication method between multifunction telephone IF packages 104 and 105 and central controller 107]
The communication method between the multifunction telephone IF package 104 and the central control device 107 is a communication method in the telephone exchange 100, and it is necessary to reliably communicate in a fixed band without delay. Therefore, there is a need for a method that ensures that a fixed band is secured.

In addition, since control system communication is irregular and the amount of communication changes, a communication method 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 software-controlled procedure.

As shown in FIG. 6, a request (RQ) is sent from the multifunction telephone IF package 104 (L / T # 0) to the central control unit (CCU) 107. The central controller 107 sends ANS = 1 to the multifunction telephone IF package 104. At this time, the central control device 107 returns ACK with an empty buffer.

Next, the multifunction telephone IF package 104 transmits an L / T control packet (SD) to the central control device 107. The central control device 107 sends the L / T control packet ACK (SDACK) and ANS = 0 to the multifunction telephone IF package 104 after the reception is normally received and the reception process is completed.

The multifunction telephone IF package 105 (L / T # 1) transmits a request (RQ) to the central controller 107. The central controller 107 does not return an ACK because the buffer is empty. The central controller 107 sends ANS = 1 to the multifunction telephone IF package 105. The multifunction telephone IF package 105 transmits an L / T control packet (SD) to the central controller 107. The central control device 107 normally receives the L / T control packet (SD) and completes the reception process, and then sends the L / T control packet ACK (SDACK) and ANS = 0 to the multifunction telephone IF package 105.

Next, the block configuration of the sensor receivers 119 and 120 will be described with reference to FIG. 7.
