ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a controlled device, controller, information control center, initialization-allowing communication system, and communication control system and medium which can be used for a communication system in which one device or more and a controller for controlling the device or devices are connected to each other by any communication means.
2. Description of the Related Art
Generally, in the case of a system in which one device or more (hereafter, this or these may be merely referred to as a device or devices) and a controller for controlling the device or devices are connected to each other by any communication means and controlled by each other, communication initialization is necessary in order to communicate with each other. The communication initialization represents setting the address number of each device in communication or the address number of the device of a communication counterpart to each device. Conventionally, the above setting has been manually and individually performed when starting a system. Operations of a conventional initialization-allowing communication system are described below by referring to the accompanying drawings.
FIG. 14
is a block diagram showing a conventional initialization-allowing communication system. The structure in
FIG. 14
is constituted with a device
10
and a controller
50
, the device
10
and the controller
50
are connected by a communication medium
20
through communication means
31
, and they can be communicated with each other. Moreover, the device
10
and controller
50
are provided with self-address setting-holding means
11
for setting and holding the addresses of their own and communication-counterpart-address setting-holding means
14
for setting and holding the address of a counterpart to be communicated with. Furthermore, the device
10
is provided with control means
15
and the controller
50
is provided with a button
12
for controlling the device
10
and control content generation means
13
for detecting that the button
12
is pressed, generating corresponding control contents, and sending the contents to the communication means
31
in addition to the control means
15
.
Operations of the conventional initialization-allowing communication system having the above structure are described below.
For the device
10
and controller
50
to communicate with each other, it is necessary to set self-addresses of their own and the address of a communication counterpart. Therefore, in order to set the self-addresses of the device
10
and controller
50
, a user first sets the self-addresses by using the self-address setting-holding means
11
. For the addresses, an address range or the like is previously specified by communication rules. For example, it is necessary that each unit has the sole address determined in a system so that the sole address is an optional number between numbers 1 and 7 and there is no duplicate number. The user sets the self-address of the device
10
to number 1 by using the self-address setting-holding means
11
of the device
10
and the self-address of the controller
50
to number 7 by using the self-address setting-holding means
11
of the controller
50
in accordance with the above rules. The self-address of each unit is determined through the above operations. Then, the user sets the address of a counterpart with which each unit communicates. In this case, because the device
10
communicates with the controller
50
and the controller
50
communicates with the device
10
, the user sets the communication-counterpart address of the device
10
to number 7 by using communication-counterpart-address setting-holding means
14
of the device
10
and the communication-counterpart address of the controller
50
to number 1 by using the communication-counterpart-address setting-holding means
14
of the controller
50
. The communication-counterpart address of each unit is determined through the above operations and thereafter, communication can be made. That is, when the user presses, for example, the button
12
indicating power-on” of the controller
50
, the control content generation means
13
of the controller
50
detects that the button
12
is pressed, generates corresponding control contents, and sends the contents to the communication means
31
. The communication means
31
transmits the above control contents from the address number 7 to the address number 1 in accordance with the contents in the self-address setting-holding means
11
and the communication-counterpart-address setting-holding means
14
. The transmitted control contents reach the control means
15
via the communication means
31
of the device
10
through the communication medium
20
and the control contents are executed. That is, when the power-on” button is pressed, the power supply of the device
10
is turned on.
To individually control a plurality of devices
10
by one controller
50
, it is necessary to specify a device to be controlled by using a control device selection switch
912
provided for the controller
50
.
Therefore, to set addresses of air conditioners
1
and
2
as the above-described initialization, the control device selection switch
912
is first set to the position indicating the air conditioner
1
, then a series of setting operations above described is performed to complete the address setting of the air conditioner
1
. Similarly to the above, the control device selection switch
912
is set to the position indicating the air conditioner
2
and then, a series of setting operations described above is performed to complete address setting of the air conditioner
2
.
As described above, the conventional initialization-allowing communication system realizes mutual communication by manually performing communication initialization.
Then, a conventional communication control system constituted with a device and a controller for controlling the device is described.
That is, in the case of the conventional communication control system, the contents for the controller to control the device are previously set in the controller. Operations of the conventional communication control system are described below by referring to FIG.
15
.
FIG. 15
is a block diagram showing a conventional communication control system. The structure in
FIG. 15
is constituted with a device
10
and a controller
50
, in which the device
10
and the controller
50
are connected to each other by a communication medium
20
through communication means
31
of the device
10
and that of the controller
50
so that they can communicate with each other. Moreover, the device
10
is provided with communication means
15
and the controller
50
is provided with a button
12
for controlling the device
10
, key input detection means
811
for detecting that the button
12
is pressed, and control content generation means
13
for generating the control contents corresponding to the key input detection means
811
and sending the contents to the communication means
31
.
Operations of the conventional communication control system having the structure are described below.
When a user presses, for example, the button
12
of the controller
50
indicating power-on,” the key input detection means
811
of the controller
50
detects that the button
12
is pressed and moreover, the control content generation means
13
generates control contents addressed to the device
10
corresponding to the control content generation means
13
and sends the contents to the communication means
31
. The communication means
31
reaches the control means
15
via the communication means
31
of the device
10
through the communication medium
20
to execute the control contents. That is, when the power-on” button is pressed, the power supply of the device
10
is turned on.
As described above, in the case of the conventional communication control system, control contents corresponding to the case in which a button is pressed is previously
