Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication control system, and particularly to a communication control system that centrally controls a plurality of terminal devices connected to the same transmission path.

[Conventional technology] With the advancement of information technology in the home, telecontrol systems have been provided that allow the use of telephone lines to operate electrical equipment from the outside. There is a need for an information transmission path that can unify the interfaces of devices and other devices and connect them to each other.

However, HBS: Home Bus System)
It was materialized as This HBS was standardized in 1988 by the Electronic Machinery Industries Association, and includes information equipment (telephones, personal computers with communication functions, etc.), housekeeping equipment (security, energy controllers, etc.), and AV equipment (teletext broadcasting). It is a type of communication control system that can be completed within the home by connecting devices (such as satellite broadcasting, satellite broadcasting, etc.) to a common transmission path and organically linking devices. , a system that allows everyone to make a choice.

Now, in order to control the terminal equipment included in the above-mentioned HBS, instructions such as "which equipment" and "what to do with it" are required. Next, this H
Three examples of control instruction methods in the BS will be described in detail with reference to the drawings.

FIG. 16 shows the first control instruction method in the conventional HBS.
It is a schematic diagram for explaining an example.

FIG. 17 shows the second control instruction method in the conventional HBS.
It is a schematic diagram for explaining an example.

FIG. 18 shows the third control instruction method in the conventional HBS.
It is a schematic diagram for explaining an example.

In conventional HBS, the control equipment in the dwelling unit is
It is mainly controlled by BC (home bus controller), and the selection of the device is controlled by accepting the device name and number input such as "Air conditioner 1", or responding to the selection input of the name such as "Living room air conditioner". and controlled it.

The details of this control method will be omitted, and only the device selection method by the operator will be explained here.

For example, as shown in FIG. 16, a control panel installed in the HBC is provided with a switch for power supply ON10FF for each device, and when the switch is pressed, the power supply of the desired control device is controlled ON10FF. In addition, as shown in Fig. 17, only the equipment number assigned to each control equipment can be inputted from the WBC button to control the desired control equipment ON10FF, or as shown in Fig. 18. There is also a method in which the name of the device to be controlled is displayed on a display installed in the HBC, and the desired control device is selected using a touch panel provided on the screen.

[Problem to be solved by the invention] In the conventional HBS control device selection as described above, when selection is made by device name and number, or only by device number, it is difficult to determine which number the target control device corresponds to. It is necessary to memorize in advance whether or not the operator is using the system, and the operability is very poor for the operator.

In addition, when displaying the installed room name and device name on the screen and letting the user select, there is a limit to the number of control devices that can be displayed on one display screen, so if there are many control devices installed, In this case, the task of turning the display screen through pages is frequently repeated, and the operability is still poor for the operator.

In addition, functions that can be executed by each control device (power supply 0N10
FF, ventilation, open, close, etc.) are different, and these are
It is difficult for C to understand this by himself. Further, conventional HBSs have not been equipped with a system that allows the HBC to recognize executable functions for each control device attached to the HBS.

In addition, even if the product is of the same type, the functions that can be executed differ depending on each control device, and even if it is assumed that the device operation menu is displayed to the operator, the executable functions will be compatible with each control device. It was difficult to display the menu.

For this reason, for example, as in the examples in Figures 16 and 17, the function menu may have to be limited to simple controls such as turning the power on, 10 FF, or all the functions that such a product can perform. Initially, a menu is displayed for the operator to select, but in reality, the selected function is not provided and the execution cannot be controlled, resulting in poor operability.

Therefore, an object of the present invention is to provide a communication control system with excellent operability that allows easy and reliable selection of terminal devices to be controlled and their executable functions connected via the same communication line. It is.

[Means for Solving the Problems] A communication control system according to the present invention is a communication control system in which a plurality of terminal devices and a controller that controls the plurality of terminal devices are connected via the same communication line. Specifically, drawing information creating means for creating drawing information representing the arrangement of the plurality of terminal devices, functional information creating means for creating executable function information unique to each of the plurality of terminal devices, and the drawing information creating means a storage means for storing the drawing information created by the function information creation means and the functional information created by the functional information creation means; a display means for reading and displaying the information stored in the storage means; Based on the drawing information and the functional information,
a designating means for an operator to designate a desired function of a desired terminal device; and a packet creating device for creating a packet for controlling the desired function of the desired terminal device in response to the designation by the designating device. , further comprising means for transmitting the packet created by the packet creation means to the desired terminal device via the communication line.

[Operation] Since the communication control system according to the present invention is configured as described above, the drawing information representing the arrangement of multiple terminal devices created by the drawing information creation means and the multiple terminal devices created by the functional information creation means Executable function information specific to each of the executable functions can be displayed to the operator via the display means. Therefore, by using the specifying means, the operator can easily specify a desired terminal device from among the plurality of terminal devices included in the communication control system, and specify a desired function from among the plurality of executable functions of the specified terminal device. It can be done quickly and reliably. Therefore, the packet creation means can easily create a packet for controlling the execution of a desired function on a desired terminal device in response to the operator's designation by the designation means. Hence,
By transmitting the created packet to a desired terminal device via a communication line, its functions can be controlled reliably and easily.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In this embodiment, the communication control system is a home bus system (hereinafter abbreviated as HBS) that centrally manages the functions of devices to be controlled (hereinafter referred to as control devices) connected to the same communication line within a dwelling unit. ), but

Next, before going into detailed explanation of the HBS in this example,
The outline of HBS will be briefly explained.

First, in the HBS of this embodiment, a floor plan information input system is constructed that creates in advance information regarding the floor plan of the dwelling unit in which the HBS is adopted and the control equipment to be installed.

(abbreviation)) is temporarily stored in a highly portable external storage medium such as a card or flexible disk, an interface for accessing these external storage media is provided on the HBS side, and then the created data is transferred from the storage medium via this interface. The information is read and imported into the HBS (data transfer). Alternatively, information created within the floor plan information entry system through data transmission between the floor plan information entry system and HBS using a communication line (such as a public telephone line) can be stored without using these external storage media. The data may be transferred and imported into the HBS.

Based on this information, the controller (hereinafter referred to as HBC) that performs centralized control of control equipment in HBS,
The floor plan and installed control equipment are displayed on the screen.

The operator can select a control device by pointing to the desired control device on this display screen. Note that the pointing method for selecting the controller includes a method of specifying by touching the screen with a finger using a touch panel, a method of specifying by moving a pointer on the screen with a mouse, etc.

After a control device is selected as described above, the HBC displays a menu of executable control functions so that the operator can select what kind of function control to perform on the selected control device. do. In other words, the installed control device information already stored in the WBC stores executable functions (hereinafter referred to as HBS commands) for each control device installed in the HBS, so the display menu includes the HB
Only executable control functions corresponding to the S command can be displayed in the menu.

Then, the HBC creates a packet of an HBS command corresponding to the control function menu selected by the operator from this display menu, and transmits the packet to the designated control device via the communication line.

As a result, the desired function of the desired control device is controlled.

As described above, the biggest difference in functionality between the HBS according to the embodiment of the present invention and the conventional HBS described above is that the functionality is improved by constructing and providing a new floor plan information input system. The point is that

Item 11 stores a device code C1 previously assigned to device sj to identify device sj, and subsequent item I2 stores a room code c2 to which the device sj is installed.

This room code C2 is the room name rj in which the device sj is installed from among the room names rj registered in the room name data RD mentioned above, which is coded and stored. Furthermore, the device number C3 is stored in item (3). This device number C3 is a number assigned to identify the same control device 31 in the same room when two or more control devices 31 with the same device code C1 are installed in the same room, that is, the same room code C2. Subsequent items ■4 and I5 indicate the location in the dwelling unit where the control device 31 corresponding to the device code C1 stored in item 11 is installed.

The last item I7 stores an HBS command that encodes and indicates the executable control function for the control device 31 of the device code C1 stored in the item 11.

As described above, the equipment name data MD in FIG. 6(b) is data created in advance by the floor plan information input system 50 and stored in the memory unit 52, but other room name data RD, equipment The SD is created by executing a program based on the processing flow shown in FIG.
This is the data stored in 2.

Next, based on the processing flow of FIG. 5, a procedure for inputting information regarding the control device 31 connected to the path line 30 of the HBS using the floor plan information input system 50;
Processing of input information will be described in detail with reference to the drawings. It is assumed that the device name data MI) in FIG. 6(b) is created in advance and stored in the memory unit 52. In addition, in residential units where the HBS is adopted,
It is assumed that two or more control devices 31 having the same device code c1 are not installed in the same room.

First, in step SIO (abbreviated as slo in the figure) of FIG. 5, a floor plan of the dwelling unit in which the HBS is adopted is created or read according to the procedure described above, and is stored in the memory section 52.
is memorized. After that, all the control equipment 3 attached to the HBS by executing the process after step S20
1 control information, that is, the room name data RD shown in FIG. 6(a) and the equipment data SD shown in FIG. 6(C) are created and stored in the memory section 52. Next, a procedure for creating the room name data RD and equipment data SD will be explained.

In the processing of steps S20 to 350, FIG.
The room name data RD of a) is created and stored in the memory section 52. First, in the process of step S20, an initial value (=0) is set in a room name counter (described later).

After that, the operator repeatedly executes the loop processing from steps S30 to S50, thereby inputting the names of all the rooms in the dwelling unit using the keyboard 54. In response to this, the CPU
The unit 51 sequentially writes and stores this key human power data as a room name rj in the room name record RDj.

In the repeated execution of this loop process, the count value of the room name counter (not shown: corresponding to the temporary storage area of the CPU section 51) is incremented from the initial value (=0) every time the room name rj is input. , the count value of the room name counter at the time of completion of inputting the room name rj is written to the room name number record HRD and stored as the room name number rc.

Next, in the processing of steps S60 to 5120,
Device code c included in device data SD in FIG. 6(C)
1. The room code c2 and equipment number c3 are created and stored in the memory section 52.

That is, in the process of step S60, the CP 0 part 51
sets an initial value (=0) to a device counter (not shown; corresponds to a temporary storage area of the CPU unit 51) in order to count the number of devices SC. Thereafter, by repeatedly executing the loop processing from steps S70 to 5120, the device code c1 and room code c2 are written in the eye chimneys 1 and 2 of the device record SDj based on the data input by the operator via the keyboard 54. be remembered. Furthermore, as mentioned above, since two or more control devices 31 having the same device code c1 are not installed in the same room, '1'' is preset as the initial value for the device number C3 of item ■3. When inputting data for registering the codes c1 and c2, the CPU section 51 stores the memory section 52 in the process of step S70.
The device name data MD is read out, and the device name mj is converted into a code and displayed on the screen on the CRT display section 55.

Therefore, the operator can look at the device name displayed on this screen and specify the desired device in the next step S80 and press the key, so the CPU section 51 inputs the device name mj entered by the key into the device code c1. Convert and write to item ■1 1':! , remember. After that, the process moves to the next step S90, which is a determination process, and it is determined whether or not the device code c1-person input has been completed.

As a result of this judgment, if the input of the device code c1 is completed (there is a key input indicating that the input is completed by the operator), the process branches to step 5140 and subsequent steps, which will be described later. The process branches and a loop process from step S70 to step 5120 is repeatedly executed. Now, in the process of step 5100, the device counter is counted up in response to the device code 01 manual input in step S80, and the device number S
C is incremented. Then step 5110
In the process of step 5120, the CPU unit 51 reads the room name data RD from the memory unit 52 and displays the room name data on the CRT display 55.The operator sees this display data and performs the above-mentioned step in the process of the next step 5120. In the process of s80, the name of the room in which the control device 31 that was entered is to be installed is entered using the key. In response to this, the CPU section 5
1 converts this into a room code C2 based on the key-entered room name rj, and writes and stores it in item I2. After that, the process returns to step S70 again and the process is repeated in the same manner.

As described above, the loop processing of steps S70 to 5120 is repeatedly executed until the determination processing of step S90 is established, and the number of devices S which is the final count value of the device counter is
C, the device code C1, room code C2, and device number c3 of each device record SDj are written to a predetermined storage area of the device data SD and stored in the memory section 52.

On the other hand, when the above-described determination process in step S90 is established, the processes in and after step 5140 are executed, and the device data S
Predetermined data is written and stored in items I4 to I7 of each device record SDj of D.

First, in the process of step 5140, the CPU section 51
reads the image data related to the floor plan input in step S10 described above from the memory section 52 and displays it on the CRT display 55.

In the process of the next step 5150, the CPU section 51
Each device record S read by accessing the memory section 52
CRT while converting the data of the DJ device code C1 and room code C2 into the corresponding device name and room name, respectively.
The screen is displayed on the display 55. Therefore, the CRT display 55 displays the floor plan of the dwelling unit in which the HBS is adopted, the name and room name of the control equipment 31 to be installed, and the information required for the arrangement of the control equipment 31 is the same. It will be displayed on the screen. The operator selects the CRT display 5 in the next step 5160.
While referring to the information for arranging the control device 31 displayed on the screen 5, use the mouse 57 to select the desired control device 31.
Specify where on the floor plan (in which room) the will be installed. This point position on the CRT screen by the mouse 57 is read by the CPU section 51 and written and stored as X coordinate C4 and Y coordinate C5 in items I4 and I5 of the device record SDj in FIG. 6(d). .

In the process of the next step 5170, the operator inputs the SA value of the control device 31 specified and placed in the process of the above-mentioned step 5160 using the keyboard 54, and the CPU section 51 accordingly inputs this as the SA value c6. Write and store in item I6.

By the way, this SA value c6 is a value determined in accordance with the HBS standard, so a detailed explanation will be omitted, but
This is a unique number (address) given to each interface unit 21 connected to the HBC 20 and is used as data for identifying the destination terminal device 11 when transmitting a data packet from the HBC 20 via the home bus 30.

Thereafter, in the process of the next step 5180, the operator inputs an executable HBS command from the keyboard 54 for the control device 31 designated and placed in the process of step 8160 described above.

In response, the CPU section 51 writes the input command to item I7 and stores command C7.

Here, the procedure for creating the above-mentioned command C7 will be explained in detail.

FIG. 7 is a schematic diagram showing an example of the data structure of item 7 in FIG.

As shown, item I7 has 3 bytes (8 bits/
The first byte stores command combination data D1 related to a control command combination method, and the second byte stores a command pattern related to a predetermined control command combination pattern (described later). Data D2 is stored, and from the third byte onward, command modification data D3 provided for modifying control commands when combining them is stored.

Next, the command combination pattern that determines the command pattern data D2 in FIG. 7 will be explained.

FIGS. 8(a) and 8(b) are diagrams illustrating an air conditioner installed indoors (hereinafter referred to as an air conditioner) and showing executable command combination patterns for this air conditioner. FIG. 8(a) shows a first pattern of command combinations, and FIG. 8(b) shows a second pattern of command combinations. Note that this command combination pattern is data stored in advance in the system 50 and the HBC 20 in the same manner. The value of either one of these two combination patterns, ie, 1" or "2", is written and stored in the command pattern data D2 of item 7.

In the first and second patterns of FIGS. 8(a) and 8(b), the command first begins with the header code H.
D. Next, there is the 0N10FF code for the power supply, which is the basic control function, and then the table selector TS (described later), followed by the cooling, heating, drying, and air cleaning functions that can be executed in the air conditioner. is encoded and stored. As shown in the figure, the header code HD given to the air conditioner is 5F'' in accordance with the HBS command standard.In other words, if the HBS command standard is followed, the HBS command is broadly related to common systems and communication functions. HK related to CT system and housekeeping
The system is classified into AVC systems related to video systems, video systems, etc., and these are classified using the Helada code HD. Therefore, since the air conditioner exemplified here belongs to the HK system, the air conditioner is identified using the header code HD (= "5F") as shown in the figure.

Now, HK commands are roughly divided into general commands common to various control devices 31 such as power supply control, and a plurality of command groups specific to each device such as an air conditioner (dehumidification, heating, cooling, etc.). These plurality of command groups are specified by the table selector TS, and as for the air conditioner, the table selector TS (="01') is used to specify a command group specific to the air conditioner, as shown in the figure.

Therefore, the actual assignment of command sequences in command patterns 1 and 2 regarding air conditioner control commands is as shown in FIGS. 8(a) and 8(b). Here, in order to simplify the explanation, only one type of header code HD and table selector TS is shown, and the header code HD
The table selector TS also serves to qualify the command string that follows.

Prepare in advance several types of patterns that are combinations of commands that can be controlled in this way, and write the number of the command pattern corresponding to the various control devices 3i (in this case, the air conditioner) in the second byte of item I7 in Figure 7. The command pattern data D2 can be set in detail. Furthermore, in order to improve the efficiency of command combinations, item I7 1.
It is assumed that command combination data D1 having a value range of 0 to 3 is set in which the byte has the following meaning.

That is, commands that can be executed when the first byte is 0 are determined by the combined command pattern specified by the command pattern data D2 set in the second byte. Also, commands that can be executed when the first byte is 1 are the combination command pattern specified by the command pattern data D2 set in the second byte, and the command modification data D3 shown in the third byte and beyond.
It is determined by the command sequence. Also, commands that can be executed in the 1st or 2nd byte are command strings based on the command modification data D3 shown in the 3rd byte and beyond from the combination command pattern specified by the command pattern data D2 set in the 2nd byte. Determined by excluding

Furthermore, if the first byte is 3, the executable commands are determined by the command string shown in the second byte and beyond, regardless of the combination command pattern.

Note that the rules regarding the method of combining control commands specified by the command combination data D1 are not limited to the rules described above.

As described above, the data manually entered from the keyboard 54 based on the previously prepared command pattern and the predetermined procedure for creating the command c7 is sent to the CPU.
In the process of step 5180, the unit 51 writes and stores it in item (7). As a result, the corresponding data will be written and stored in all items 11 to -I7 of the device record SDj.

Thereafter, in the determination process of the next step 5190, it is determined whether writing of predetermined data to items 11 to 17 has been completed for all device records SDj registered in the device data SD. This determination is made based on the presence or absence of a key human effort by the operator to indicate completion of data creation regarding the device record SDj. When it is determined that the series of data creation has been completed in this discrimination process,
This process flow ends, but as long as the data creation is not completed, that is, while the determination process in step 5190 is not satisfied, the loop process from step 5140 to step 5190 is repeatedly executed to complete all device records registered in the device data SD. Predetermined data is written and stored from item 1 of SDj to F.

Next, based on the process flow shown in FIG.
How the data stored in j is created will be explained with reference to the drawings.

FIG. 9 is a floor plan of a dwelling unit in which the HBS shown in FIG. 1 above is adopted.

FIG. 10 is a diagram showing the contents of the room name data RD corresponding to the HBS shown in FIG. 1 above.

FIG. 11 shows device name data MD according to an embodiment of the present invention.

FIG. 12 is a screen display of the floor plan shown in FIG. 9 above.

FIG. 13 is a diagram showing the contents of the equipment record SDj of the air conditioner arranged in FIG. 12 above.

FIG. 14 is a diagram showing a screen display of a function menu based on the device record SDj shown in FIG. 13 above.

FIG. 15 is a schematic diagram showing the contents of the packet 40 created when power ON is selected in the function menu shown in FIG. 13 above.

Currently, a floor plan as shown in FIG. 9 is stored in the floor plan information input system 50 according to the HBS shown in FIG. If so, the room name data RD will be set and stored as shown in FIG. 10 in the floor plan information input system 50. Then the H
Regarding the designation of the control equipment 31 installed in the BS, the equipment name mj is encoded in advance in the floor plan information input system 50 as shown in FIG.
Assume that it is stored as .

Also, at the coordinate position of the floor plan shown in Figure 12 (X coordinate c
4 and Y coordinate c5) Specify the air conditioner installation position using the mouse 57. Next, set the SA value C6 of this air conditioner to 82 (hexadecimal) and manually input the key. Next, command C
7 is specified as the command string in the first pattern shown in FIG. 8(a) above except for the air cleaning function. As described above, when data regarding this device Sj, ie, air conditioner control, is input, data will be set in the device record SDj as shown in FIG. 13.

As described above, the floor plan and equipment data SD created on the floor plan information input system 50 and stored in the memory section 52 are read out from the memory section 52 by the CPU section 51 and sent via the card interface section 53. I
It is written and stored in the C card 14.

Note that by storing software that executes these data processes in the IC card 14 in advance,
It is also possible to provide each household or individual with an environment in which they can easily check the information content regarding the control device 31 and update data using the electronic notebook 59.

After that, the card insertion slot 1 of the HBC 20 shown in FIG.
By inserting the IC card 14 into the HBS 20 via the HBS 5, the equipment data SD of the installation control equipment 31 and the information regarding the floor plan created in the floor plan information input system 50 are transferred and imported into the HBS. That is, the CPU section 22 of the HBC 20 reads data stored in the IC card 14 via the card interface section 25 and transfers the data to the memory section 24 .

This means that the information created by the floor plan information input system 50 has been transferred to the HBS.

Thereafter, in the device control of the control device 31 by the HBC 20, the CPU unit 22 displays the image information of the floor plan given from the IC card 14 on the display 12 or 13.
At the same time, the icon of each control device 31 specified by each device code C1 of the device data SD is displayed at the coordinate position on the screen specified by the X and Y coordinates c4 and c5 of the device data SD. . As a result, the display 12 or 13 displays a drawing equivalent to the above-mentioned FIG. 12. At this time, when the operator touches the touch panel provided on the display 12 or 13, the control device 3 has an X coordinate c4 and a Y coordinate c5 that are most approximate to the X and Y coordinates indicating the touched position.
1 is considered to have been selected. At this time, if multiple control devices 31 are installed close to the coordinate position on the floor plan specified by the X coordinate c4 and Y coordinate c5, the coordinate part is further enlarged and displayed again. Processing such as selection may be performed using a touch panel.

By the above operations, the CPU section 22 or one control device 3
1 is selected and designated, the device record SDj of the designated control device 31 is read out from the memory section 24. This readout process includes the X coordinate c4 and the Y coordinate c4.
5 as a search key, the memory section 24 is searched, the corresponding device record SDj is read out, the command section c7 is decoded, and functions executable by the control device 31 are displayed as a menu on the display 12 or 13. At this time,
When the cafeteria air conditioner shown in FIG. 12 above is selected by the operator's touch panel operation, the CPU section 22
reads out the device record SDj shown in FIG. 13 above from the memory section 24, and displays a control function menu as shown in FIG. 14 on the display 12 or 13. At this time, assuming that the operator who viewed the display menu in FIG. 14 specified the power-on control function via the touch panel, the CPU section 22 would respond with commands C7 and 5A.
(HBS as shown in FIG. 15 using iic6)
A packet 40 containing the command is created.

Thereafter, this package 40 is sent to the home bus 30 via the interface section 21 and supplied to the air conditioner 307 in the cafeteria shown in FIG. As a result, the dining room air conditioner 307
is powered on and controlled by the HBC 20.

Note that the CPU unit 22 of the HBC 20 processes the data stored in the inserted IC card 14 by first transferring the data to the memory unit 24 and then accessing the memory unit 24, or by accessing the memory unit 24.
Data processing may be performed while directly accessing the IC card 14 via the IC card 5.

Here, packet 40 including the HBS command in FIG.
I will explain about it.

This packet 40 is created by the CPU section 22, sent to the home bus 30 via the bus interface section 21, and includes a self address SA value, a destination address DA value, a header code HD, and an operation code OPC. In the case of this packet Δ0, self address SA value (=O
O) indicates the HBC 20 that is the source of the packet, and the destination address DA value (=82) indicates the interface unit 207 that controls the air conditioner 307 of the cafeteria that is the destination of the packet. Also, header code HD
(=5F) is the operation code OPC that follows
(=80) indicates that the attribute is housekeeping (HK) type. Therefore, this packet 40
When sent from the BC 20 to the home bus 30, the interface unit 207 connected to the cafeteria air conditioner 307 reads the destination address DA value (=82) of the packet 40 as shown in FIG. It is recognized that the packet 40 was sent to itself. Therefore, the packet 4o transmitted in response to this recognition result is taken into the interface unit 207 and its operation code OPC (=80) is input.
By decoding the code, turning on the air conditioner 307 can be controlled.

In this way, the installation position of the control device 31 in the dwelling unit, the SA
HBC20, which combines a graphic display and a touch panel, stores control equipment data SD in which values and executable control commands are stored, as well as floor plan information.
By performing data processing in , it is possible to create a packet including a control signal for the control device 31, and it is possible to provide an HBS with excellent operability.

In this embodiment, the information regarding the installed control equipment 31 is supplied to the HBS using the IC card 14, but the external storage medium for supplying this information is the IC card 14.
For example, it may be a flexible disk. Furthermore, this information is supplied to the HBS by data communication via a communication line such as the telephone line 26, and the data can be changed or corrected without going through the electronic notebook 59.
It may also be done directly at 0.

As is clear from the above description, the HBS according to the embodiment of the present invention provides information on the floor plan of the dwelling unit and the Provides an environment in which equipment can be easily selected by providing information about the installed control equipment 31, displaying a floor plan and equipment on a graphic display, and having the operator perform input using a touch panel. can do. Further, by using the command c7 of the device data SD, only executable functions can be displayed in the menu, so it is possible to provide the operator with an HBS that can eliminate misunderstandings and wasteful operations.

In addition, by making it possible to arbitrarily update data regarding the installed control equipment 31 using the electronic notebook 59, the control equipment 3
1 can be easily added, deleted, and changed models.
The flexibility of the system is ensured, and furthermore, it is possible to flexibly deal with the purchase and replacement of the control equipment 31 in each home.

Furthermore, by preparing several types of commands for controlling the installed control equipment 31 in advance by patterning them as described above, it is also possible to efficiently utilize the limited memory capacity of the IC card 14, etc. .

[Effects of the Invention] According to the present invention, the drawing information and functional information created by the drawing information creating means and the functional information creating means are displayed to the operator using the display means, thereby allowing the operator to select the desired terminal. It is possible to easily and reliably specify the desired functions of the device.

In addition, since a packet is reliably created to perform the desired function on the desired terminal device specified by the operator, using this created packet ensures that the desired function is performed on the desired terminal device. This makes it easy to control the process.
