Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided in a guest room of an accommodation facility such as a hotel or an inn, for example, equipment such as air conditioning equipment and lighting equipment, security equipment such as an auto lock device, and other sensors. The present invention relates to a centralized control method for accommodation facilities that is centrally managed using a telephone line.

[0002]

2. Description of the Related Art In accommodation facilities such as hotels and inns, from the viewpoints of improving service to guests and safety, guest room air conditioners, lighting, auto lock, equipment such as fire detectors, security equipment, and various sensors, etc. Attempts have been made to carry out centralized management of.

Conventionally, such centralized management has, for example, arranged a computer device for a main controller in a control room, mounted controllers on air conditioners and lighting devices in each guest room, and connected the controllers to the computer device. Connect with a cable. Similarly, auto locks, fire detectors, etc. in each room are also connected by connecting cables to computer devices.

[0004]

However, in the case of connecting the computer device for the controller to the equipment and sensor in each room with the connection cable as described above, a dedicated cable must be installed up to each room. For,
There is a problem that installation costs are high.

In particular, when laying in an existing building, it is necessary to bury it in the wall surface, etc. Therefore, there is a problem that it must be closed for a long period during the construction period, and the construction cost is also high.

Therefore, an object of the present invention is to provide a centralized control method for a guest room, which enables centralized control of facility equipment, security equipment, sensors and the like in the guest room without the need for laying cables.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a main controller is connected to a switchboard of an accommodation facility, and a telephone line connected from the switchboard to each guest room is connected to a facility equipment of the guest room. A security controller and various sensors are connected to a guest room controller that controls the equipment and collects data according to a command from the main controller, and the main controller connects the guest room controller in each room via a private telephone line. The method of controlling the device and the sensor by communicating with

At this time, the line connection between the main controller and each cabin controller is performed by sending a calling signal from the main controller a predetermined number of times to the cabin controller, or the line connection is performed from each cabin controller. The main controller may transmit the next line connection time to the guest room controller when the communication is performed.

[0009]

In such a centralized control method for accommodation facilities, the main controller accesses the guest room controller connected to the telephone line of each room through the exchange.

Therefore, the main controller can individually control the control data and the like with the guest room controller in each room to control the facility equipment, security equipment, sensors and the like in each room.

At this time, if the main controller communicates by utilizing the idle time of the telephone call, the main controller can centrally manage the control of each room without hindering the telephone call.

At this time, in the method of connecting the line between the main controller and each guest room controller by sending a calling signal a predetermined number of times from the main controller to the guest room controller, the line is connected to each guest room controller. The number of ringing signals sent when the call is sent is counted, and whether the connection is due to a telephone call or an access from the main controller is determined depending on whether or not the number matches the predetermined number of times. Determine. At that time, if the access is from the main controller, a connection is made to communicate.

For example, in the case where the main controller sends a ringing tone once to the passenger room controller and replaces the connection request signal by temporarily disconnecting the passenger room controller, the passenger room controller outputs O of the detected calling signal.
The interval of the N signal is measured, and it is determined whether it is a request signal or not depending on the presence or absence of a calling signal after the interval period.

As described above, since the call signal is used as the connection request signal, communication with each cabin controller can be easily performed without using a complicated procedure.

Further, in the method in which the line connection is made by calling from each guest room controller and the main controller transmits the next line connection time to the guest room controller at the time of the communication, when the main controller makes the communication, By transmitting the start time of the next line connection to the room controller, the main controller notifies the room controller of the available time. When the specified time comes, the guest room controller notified of the connection time makes a call to the main controller to connect and communicate.

For this reason, each cabin controller can communicate with the main controller without duplication and without waiting time. At this time, if the time can be changed according to the management status of each guest room, finely managed can be performed for each guest room.

The hybrid circuit 13 mixes and distributes transmission / reception carriers such as DTMF signals.

The amplifier 14 comprises a programmable gain amplifier and a summing amplifier, adjusts the transmission level,
At the same time, the DTMF signal and the carrier of the modem of the control unit 7 described later are matched.

The filter equalizer 15 is composed of a BPF for removing unnecessary noise and an equalizer for amplitude and phase correction, and compensates the quality of the transmission / reception carrier.

The controller 16 controls each of these circuits and exchanges information with the exchange 1 according to a predetermined procedure.
The cabin controller 5 and the exchange 1 are connected.

The control unit 7 includes a modem 17 and the modem 17
It is composed of a microcomputer 18 and an I / O device 19 connected to.

The modem 17 is connected to the line connection unit 6 and performs modulation / demodulation of communication data so that data can be transmitted through the telephone line 4.

The microcomputer 18 performs a series of control operations (including transmission of measurement data, for example) based on the received control data.

The I / O device 19 is connected to a control target and a measurement target, and inputs and outputs to the target under the control of the microcomputer 18.

In the case of the embodiment, the I / O device 19 is provided with a room temperature and humidity sensor 20, a room temperature controller and a humidity controller 21 for controlling the operation of the air conditioner, and an air conditioner for controlling the temperature and humidity of the entire passenger compartment. Detects whether cold water with a specified temperature is normally supplied to the fin coil,
In order to manage the operation of the air conditioner, for example, it is connected to the temperature sensor 22 provided in the fin coil of the air conditioner via the A / D converter, and the lighting device is turned on so that the lighting of the cabin can be managed. It is also connected to a security device such as an operation relay 23, an auto lock 24, and a fire detector 25 for use in the.

This embodiment is configured as described above. Next, the connection control operation between the main controller 3 and each guest room controller 5 will be described to explain the centralized control method for accommodation facilities of the present invention. .

The main controller 3 is connected to the extension line of the exchange 1, and, for example, data such as temperature and humidity set values for each room and reference values of the temperature of cold and hot water supplied to the fin coils, and an illumination plan. The lock state display program and the fire alarm operation state display program are stored in the file, and control is performed based on the file.

Generally, as shown in FIG. 3, the main controller 3 connects (dials) to the guest room controller 5 in each guest room in a fixed order and performs a polling operation to inquire whether or not there is a call origination request. A call origination request from the guest room controller 5 is accepted.

At this time, in the embodiment, the ringing tone is transmitted once to the cabin controller 5, and the connection is temporarily released to replace the request signal.

On the other hand, the passenger room controller 5 detects the interval of the ON signal of the calling signal detected by the CI detector 10 (the ringing sound is normally ON for 0.5 to 1.5 seconds, 1.5 to 1.5 seconds).
Repeatedly turned OFF for 3.5 seconds), and whether or not it is a request signal is determined by the presence or absence of a calling signal after the interval period.

That is, when the calling signal ends once,
The main controller 3 recognizes that it is data transmission by polling transmission control, and if the call signal continues twice or more, it recognizes that it is a call.

Therefore, when the calling signal continues for two or more times, the DM relay 11 is switched to connect the auxiliary telephone 8 and the exchange 1 so that the telephone conversation can be performed.

On the other hand, when the calling signal is once, DM
The relay 11 is switched to connect the control unit 7 and the exchange 1.

At this time, if there is no call origination request to the cabin controller 5, the connection is stopped and the standby state is entered. If there is a call origination request at this time, the control unit 7 outputs a control signal to the controller 16 of the line connection unit 6 to dial and call the main controller 3.

When there is a call, the main controller 3 accepts a request signal, mutually confirms the communication partner, and transmits / receives data.

Incidentally, a basic procedure, a BSC procedure, an HDLC procedure or the like can be used for this communication procedure.

On the other hand, when it is desired to transmit data from the main controller 3 to the guest room controller 5, the polling operation is stopped and the destination guest room controller 5 is called by dialing.

In this case as well, as described above, the main controller 3 sends a transmission signal once to the partner room controller 5, and then once releases the connection.

Guest room controller 5 to which an outgoing signal is transmitted
In the same manner as described above, the dialing and calling of the main controller 3 are performed to mutually confirm the communication partner, and then the data is transmitted and received.

At this time, if these data transmissions overlap with the use of the side-by-side telephone 8, the guest room controller 5 sets L
Since the DC loop is detected by the P detection circuit 9, the transmission is postponed and the transmission is waited until the use of the auxiliary telephone 8 is completed.

Naturally, the transmission wait is performed even when the main controller 3 is connected to another guest room controller 5.

Similarly, even when the main controller 3 accesses the guest room controller 5, if the other party guest room controller 5 is talking on the auxiliary telephone 8, the transmission is waited.

In this way, by using the in-house telephone line 4, the main controller 3 issues a control command for setting temperature and humidity to the temperature and humidity controllers in each room and turning on / off the air conditioner.
It transmits control commands such as OFF and ON / OFF of lighting equipment.

On the other hand, from the cabin controller 5 to the main controller 3, the temperature detected by the fin coil, the room temperature and humidity, the auto lock and the data detected by the fire alarm, etc. are transmitted, and by communicating with each other, Main controller 3 for guest room equipment, security equipment, sensors, etc.
Central control is performed by.

FIG. 4 shows a second embodiment.

The second embodiment shows another connection method between the main controller 3 and each guest room controller 5.

In this connection operation, contrary to the case of the first embodiment, each guest room controller 5 sequentially calls the main controller 3 to communicate the control data.

The call from each guest room controller 5 is controlled by the time data transmitted from the main controller 3.

That is, each guest room controller 5 is, for example,
The microcomputer 18 is provided with a timer (not shown) for communication management, and when the timer expires, the timer shown in FIG.
As shown in FIG. 3, the main controller 3 is dialed to perform a connecting operation and control data and the like are transmitted.

At this time, the main controller 3 transmits the next connection time as time data to the connecting guest room controller 5 together with the control data and the like.

On the other hand, the cabin controller 5 to which the time data has been transmitted sets the received time data in the communication management timer. Then, when the timer in which the new time data is set is up, the connection operation to the main controller 3 is performed and the control data and the time data are transmitted.

At this time, the time data transmitted from the main controller 3 to each guest room controller 5 has a free time of the main controller 3 so that the connection operation from each guest room controller 5 and the data transmission time after the connection do not overlap. Is set. For the setting, for example, if the main controller 3 is provided with a time data management table or the like, management can be performed easily.

Therefore, the connection between the guest room controller 5 and the main controller 3 can be efficiently performed without duplication and without waiting time.

At this time, each guest room controller 5
By giving priority to the connection time, connection order, etc. in the time data transmitted to, it is possible to manage a specific guest room in detail.

By the way, if the use of the auxiliary telephone 8 overlaps when the guest room controller 5 is connected to the main controller 3, the guest room controller 5 waits for transmission until the use of the auxiliary telephone 8 ends. Either, or the timer operation is performed again according to the previously set time data, and then the connection operation is performed. Selection of these operations may be determined in advance between the main controller 3 and the guest room controller 5 prior to the start of centralized management.

Here, in the case of adopting the former method, if the connection interval between each guest room controller 5 and the main controller 3 is set relatively large, the duplication of the connection operation can be reduced. Therefore, the connection can be made without delay. Therefore, even if the auxiliary telephone 8 is used, there is an effect that the number of times of connection does not decrease and the number of times of management does not decrease.

At this time, if the connections between the guest room controllers 5 to the main controller 3 overlap, the processing such as waiting for transmission may be repeated.

When the latter method is adopted, the guest room may not be managed by using the telephone 8, but the connection from each guest room controller 5 to the main controller 3 may be duplicated. Therefore, there is an advantage that communication control is easy.

As described above, when these methods are used, the centralized control of the guest room can be performed without the need for additional cable laying. Therefore, it can be easily installed especially in an existing building.

As a result, for example, in terms of air conditioning, conventionally, in an existing hotel or the like, the air conditioning equipment is set to be turned on / off and the room temperature is set by a temperature controller provided for each room. There are many women, children, and elderly people who are weak in the mechanism and do not understand how to operate the temperature controller and can not adjust the room temperature optimally, which may give an uncomfortable impression, but such problems are easy. Can be resolved.

[0074]

[Effects] According to the present invention, since the centralized control of the control of equipments, security devices, sensors, etc. in a plurality of guest rooms is performed by using the private telephone line by the above method, the connection for the centralized control is provided. There is no need to lay cables up to each room, so laying costs can be reduced.

Therefore, installation in an existing building is easy,
In addition, at this time, since the guest room controller may be installed in each guest room to connect to the equipment equipment in the guest room, the work can be performed in the guest room or on a block basis for each floor. Therefore, installation work can be performed without taking a break.

In particular, in the method of connecting the main controller and each guest room controller by sending a calling signal from the main controller to the guest room controller a predetermined number of times, the connection between the two can be performed without using a complicated procedure. It

If the main controller transmits the next line connection time to the guest room controller when the above-mentioned line connection is made from the guest room controller, there is no waiting time for both connections. You can do it efficiently.
