DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is used for digital communication in a distributed private branch exchange. In particular, the present invention relates to a technology for accessing an environmental control device by an extension subscriber terminal.

[0002]

2. Description of the Related Art In each office occupied in a tenant office building or the like, the control of lighting and / or air conditioning equipment of individual sections is controlled by a control panel in which switches and controllers are provided in several places for each section. Have been.

[0003] All wiring of this control panel is carried out by a building management device (reference document NEC Technical Report Vol. 43 No.
6/1990 p. 88 to 94), and the lighting and / or air conditioning equipment of each section is controlled by an environment control device connected to the building management device.

[0004]

A person who has a desk far from the control panel must walk to the control panel every time the lighting and / or air conditioning equipment is controlled.

[0005] Further, in terms of facilities, since the wiring from the control panel is connected to the building management apparatus, a large number of wirings are required in addition to the power wiring and the wiring of the extension subscriber terminal and the private branch exchange.

[0006] The present invention has been made in such a background, the lighting and or air conditioning equipment is controlled by a multifunctional telephone at hand to make environmental control more familiar, and time-divisional digital lines save. It is intended to provide a device for achieving linearization.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a multifunction private branch exchange having a multifunction telephone having a voice communication function and a data communication function, and a private branch exchange accommodating the multifunction telephone. The exchange is provided with an interface that can be exchanged with the multi-function telephone, and this interface transmits control data directly to and from an environmental control device having a control circuit for lighting and / or air conditioning equipment of the building in which the private branch exchange is installed. Digital interface to send and receive
Comprising a Esu, the environmental control system is characterized in that the a direct controllable constituted by control code sent from the multi function telephone.

[0008]

[Function] With a multifunctional telephone having a data communication function,
The CPU provided in the environment control device is directly accessed by the time division signal. In addition to the data communication function, the multifunction telephone also has a display for displaying the returned control result.

[0009] A distributed private branch exchange having a local node accommodating extension subscriber terminals and distributed as a switching device, and a center node for centrally controlling the local node and connecting to a public network. By using the partition, the partition to be controlled can be classified according to the address in the CPU provided in the environment control device assigned to each local node.

[0010] The building management device may be configured to centrally manage the program information of the environmental devices and take appropriate measures.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. FIG. 1 is a configuration diagram of an embodiment of the present invention.

The present invention relates to a multi-function private branch exchange having a multi-function telephone 5 having a voice communication function and a data communication function and a private branch exchange 1 accommodating the multi-function telephone 5. Is provided with an interface 6 that can be exchangeably connected to the multi-function telephone 5. The interface 6 includes an environment control device 8 having a control circuit for the lighting equipment 11 and / or the air conditioning equipment 10 of the building in which the private branch exchange 1 is installed. This environment control device 8 is characterized in that it is configured to be controllable from the multi-function telephone 5.

Next, the operation of the embodiment of the present invention will be described with reference to FIG.

Since the voice communication function is performed by a well-known procedure, the data communication function will be described here.

When the special button for data communication call of the multi-function telephone 5 is pressed, the digital line circuit 4 detects the call and notifies the processor 2 of the private branch exchange 1 of the call. The processor 2 inquires of the interface 6 whether the call can be received. If the call can be received, the processor 2 issues a connection instruction to the interface 6. The processor 2 connects a link 13 of the time division switch 3 between the digital line circuit 4 and the interface 6. When this link 13 is connected, the multifunctional telephone 5
The function as an extension subscriber terminal is suspended, and the function as a terminal of the environment control device 8 is activated.

The environment control device 8 has a CPU capable of inputting an environment control program, and controls the lighting equipment 11 and / or the air conditioning equipment 10 for each section. The contents of the environmental control program include blinking and dimming of each section of the lighting equipment 11, opening and closing of the air conditioning equipment 10 and temperature setting, as well as time setting within 24 hours a day and automatic opening and closing of equipment. Control is also performed.

FIG. 2 is a configuration diagram of the interface 6. The interface 6 has a port of RS232C, and is connected to the environment control device 8 by RS232C7.

If there is a change in the contents of the environmental control program, the change is sent from the multifunctional telephone 5 to the CPU of the environmental control device 8 via the control code. The control code is transmitted to the interface 6 via the link 13 set previously.
, And furthermore the interface 6 and the environmental control device 8
And the control code is stored in the environment control device 8.
To arrive. The control result is returned to the multi-function telephone 5 along the route opposite to the control code, and can be displayed on the display board of the multi-function telephone 5.

The display contents of the multi-function telephone 5 are checked, and if the environment control program has been changed to a desired one, the pressed special button is released. Link 1 by releasing the special button
3 is released, and the multifunction telephone 5 resumes its function as an extension subscriber terminal.

The program contents changed by the environment control device 8 can be collected and managed by the building management device 12 via the bus 9.

The partitions to be controlled can be classified according to the address in the environment control device 8 used for the distributed private branch exchange 1 and assigned to each local node. Also, a plurality of multi-function telephones 5 can be installed in the same section, and the operation of changing the contents of environmental control in the same section from the plurality of multi-function phones 5 can be performed. Conversely, the function of the private branch exchange 1 for setting the service level of the telephone can limit the number of multifunctional telephones 5 that can control the environment.

Although the interface 6 and the environment control device 8 are described to be connected by the RS232C7 here, they can be connected by HDLC (high-level data link control procedure).

[0023]

In a tenant office building or the like, a multifunctional telephone, which is an extension subscriber terminal installed at hand, is used as an environmental control device terminal without providing a dedicated control panel for controlling lighting and / or air conditioning equipment. Thus, lighting and / or air conditioning equipment can be controlled.
In addition, the environment control state can be confirmed by returning the control result.
