Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a guest room condition monitoring and control system in which the condition of each guest room in a hotel or the like is centrally monitored and controlled from a central management side via a digital private branch telephone exchange. be.

[Conventional technology]

Regarding this kind of technology, for example, the paper "Current situation and future prospects of automatic meter reading system" (Journal of Institute of Electronics and Communication Engineers 12/'85 Vol. 6B, No. 12)
A no-ringing line system using a telephone line is known, as shown in pp. 1330-1332). Automatic meter reading is performed by receiving a call to a terminal network control device connected in parallel to a telephone without ringing the bell of the telephone.

[Problem that the invention seeks to solve]

However, in the case of the conventional no-ringing line system, if a subscriber starts driving while a meter reading is being performed, the meter reading is interrupted and priority is given to making a telephone call. Therefore, generally during phone use,
For example, it is impossible to monitor and control the state of the cabin.

The purpose of the present invention is to check the condition of a guest room where a telephone is installed.
To provide a cabin condition monitoring and control system that allows monitoring and control of the telephone even when the telephone is in use.

[Means for solving problems]

The above purpose is to enable terminal control equipment connected in parallel to the telephones installed in each guest room, housed in a digital private branch telephone exchange together with the telephones via time-division multiplex digital circuits. The central management side calls the housed terminal control device via the digital private branch telephone exchange, and exchanges monitoring data, etc. with the device.
This is accomplished by sending control data to each other.

[For production]

The telephone set and the terminal control device are connected in parallel to the same line, but because the line is accommodated in a digital private branch telephone exchange as a time-division multiplex digital circuit, the terminal control unit is connected to the digital private branch telephone exchange regardless of the operation of the telephone set. It can be connected to the central management side via a telephone exchange. Monitoring data is sent from the terminal control device to the central management side, and if control data is sent from the central management side to the terminal control device based on this monitoring data, the central management side can arbitrarily monitor and control the state of the guest room. It is possible.

〔Example〕

The present invention will be explained below with reference to FIGS. 1 to 3.

First, the relay system according to the present invention will be explained. FIG. 1 shows an example of the relay system. As shown in the figure, a central control unit (CC) 2 is connected to a digital private branch exchange (DPBX) 1 that exchanges and processes voice and various data as digital information via an adapter (ADP) 3a and a time-division multiplexing digital line 8a. The compatible (extension) telephone 4 and terminal control device (RC) 5 are equipped with an adapter (
ADP) 3b, and is accommodated via a time division multiplex digital line 8b. The terminal control device (RC) 5 also includes an air conditioning temperature control device (S) installed in the guest room.
S) 6, power on/off switch (SW) 7, etc. are accommodated as terminal devices, and their status is determined by the terminal control device (RC).
The telephone 4 and the terminal controller (RC) 5 are connected to an analog signal line 9, and the telephone 4 and the terminal control device (RC) 5 are connected to an adapter (ADP) 3a through a signal line so as to be monitored and controlled by the central pipe embedded ff (CC) 2 through the analog signal line 9. , is accommodated in the adapter 3b via the digital signal line 10, but FIG.
DP) 3b shows the configuration.

Adapter (ADP) 3a also has the same configuration,
In this case, the entire interface section (IF) 31
, control unit (CPU) 32, audio copier/7 controller (C
ODEC) 33 and data interface section (DT
I) It is composed of 34 parts. Central control unit (CC) 2 is a terminal control bag! It is accommodated in adapter (ADP) 3a in the same way as (RC) 5, but
The interface section (IF) 31 separates the channels of the digital multiplexed signal from the time division multiplexed digital line 8b and then sends the digital multiplexed signal from the telephone 4. While distributing to the terminal controller (RC) 5, the telephone 4. Signals from each terminal control device (RC) 5 are digitally multiplexed. Further, the codec section (CODEC) 33 converts the analog signal from the telephone 4 into a digital signal and sends it to the interface section (IF) 31, while converting the digitized audio signal from the interface section (IF) 31 into an analog signal and converts it into a digital signal from the telephone 4. It is intended to be sent to The data interface section (DTI) 34 also includes an interface section (IF) 31. The physical interface of digital signals exchanged between the terminal controllers (RC) 5 is matched. Control unit (CPU) 3
2, the telephone 4 and the terminal controller (RC) 5 are connected to an interface section (IF) 31.2 in order to operate as a terminal device of a digital private branch exchange (DPBX>1).
The codec section (CODEC) 33 and data interface section (DTI) 34 are controlled in a predetermined manner.

FIG. 3 shows an example of a signal format on time-division multiplex digital lines 3a and 8b that is transmitted and received between adapters (ADP) 3a and 3b via digital private branch exchange (DPBX) 1. . The transmission method in this example is a so-called ping-pong transmission method, and the first half of the period t of the digital multiplexed signal is assigned to the transmitting side signal SND, and the second half is assigned to the receiving side signal REC. The transmitting side signal SND is the synchronizing signal 5YNS, the first bearer channel signal BIS, the second bearer channel signal B2S and the control data channel signal DS, and the receiving side signal REC is the synchronizing signal 5YNR.

It consists of a first bearer channel signal BIR1, a second bearer channel signal B2R, and a control data channel signal DR.

Now, to explain the specific operation, when the telephone 4 makes a call, the codec section 3 in the adapter 3b sends a call to that effect.
3, the control unit 32 is notified, and the control unit 32
Then, the control data channel signal DS should be used to transmit that the telephone 4 has made a call (which controls the interface section 31. The control data channel signal DS is sent from the interface section 31 to the time division multiplex digital line 8b. The digital private telephone exchange 1 knows that the telephone 4 has made a call by transmitting the dial tone to the digital private telephone exchange 1 through the digital private telephone exchange 1. As a result, a dial tone is sent back from the digital private telephone exchange 1 to the telephone 4. However, the dial tone is the first bearer channel signal BI which is the audio codec side channel.
By setting a digitized dial tone signal as R from the digital private branch telephone exchange 1, it is sent back to the telephone set 4. At the same time, the digital private telephone exchange I sends to the telephone 4 a control data channel signal DR indicating that the call from the telephone 4 has been accepted.

Thereafter, a series of operations such as dial reception, calling signal transmission, ringback tone transmission, response, call, disconnection, and end of call are performed using the first bearer channel signal BIS.

B I R, control data channel signals DS, D, H
This will be done by.

Next, to explain the operation when monitoring and controlling the state of a guest room, the central management device 2 is housed in the digital private telephone exchange 1 as a kind of digital telephone terminal via an adapter 3a. When calling a terminal control device 5 currently in use to monitor and control its cabin status, the telephone number of the terminal control device 5 is dialed by the central management device 2 immediately after the call is made. When the central management device 2 makes a call, the adapter 3
It is detected by the data interface unit 34 in a and is notified to the control unit 32. Control unit 32
Now, in the same manner as when a call is made by the telephone 4, in order to notify the digital private branch telephone exchange l that the central management unit 2 has made a call using the control data channel signal DS,
It controls the interface section 31. If the notification is received, the digital private telephone exchange 1
The central management device 2 sends back a control data channel signal DR indicating that the call has been accepted from the central management device, and then the central management device 2 transmits the dial information of the terminal control device 5 by a control data channel signal DS. It is now possible to do so. The digital private branch telephone exchange 1 that receives this information analyzes it and uses it to control the terminal control device 5.
After determining the corresponding time-division multiplexing digital line 8b, a signal for calling the terminal control device 5 is transmitted using the control data channel signal DS.

This signal is received by the interface section 31 in the adapter 3b and is notified to the control section 32, which causes the control section 32 to place the data interface section 34 in a calling state.

When the terminal control device 5 responds to this call, the response is detected by the data interface section 34 and notified to the control section 32, and based on this notification, the digital private branch telephone exchange 1 receives the response for control purposes. It is adapted to be transmitted by a data channel signal DS. The digital private branch telephone exchange 1 that received this transmits the response to the central management device 2 via the adapter 3a using the control data channel signal DR, thereby establishing an end-to-end connection between the central management device 2 and the terminal control device 5.・It is the part that is connected at the end. In this connected state, control data is transmitted from the central management device 2 to the terminal control device 5, and monitoring data is transmitted from the terminal control device 5 to the central management device 2, but these data are transmitted through the second bearer channel. The reception is carried out by the signal B2S, and the reception is carried out by the second paired channel signal B2R. The subsequent disconnection and end of the call are the same as those at the time of making a call.

As described above, by calling the terminal control device installed in each guest room to the central management side via the digital private branch telephone exchange and sending and receiving various monitoring and control data, the central management side can easily monitor and control the guest room status. shall be obtained.

Although the present invention has been described above by taking guest rooms in hotels and the like as an example, it is not limited thereto, and is also effective when grasping the status of each tenant in the same building or the status of a hospital room.

〔Effect of the invention〕

As explained above, the present invention has the effect that the state of a guest room can be easily and economically monitored and controlled even when the telephone installed in the guest room is in use.
