2. Description of the Related Art A conventional technique will be described with reference to FIGS.

FIG. 15 is a diagram showing an example of a network configuration to which the present invention is applied, and shows a conventional example in which the system shown in the figure is an HBS. It is assumed that the functional configuration of each terminal shown in FIG. 15 has contents as shown in FIG. As shown in FIG. 16, the terminal a 151 and the terminal c
HBC 153 is an information channel controller function
Assume that it has functions 161-1 and 163-1. In HBS, these individual functions of each terminal are provided by sub-devices (SDA
18, and an operation code (denoted as OPC) 183 and an operand code (denoted as OPR) 184 which are commands for designating control in a message exchanged on the transmission line 150 as shown in FIG.
Other than the SSDA181 and DS that specify this SDA
The DA 182 exists, and the function can be easily controlled. Therefore, as shown in FIGS. 19 and 20, the configuration of the processing unit of the terminal is the SDA determination processing unit 192 for determining the function and the control processing unit 1 for each function for performing the control processing related to each function.
93-196 and 201-204. As a specific service, a case of information channel management processing will be described. FIG. 24 shows the HBC shown in FIG.
FIG. 3 is a diagram illustrating a configuration example including up to an address control unit. FIG. 25 is a diagram showing a specific configuration example of the address table that can be set as shown in FIG.

In general, since the address of the controller is not uniquely determined, the terminal receiving the service transmits a service request message on the transmission line 150 by simultaneous broadcast as shown in FIG. 171). The controller receiving this message sends a response message to the request to the request originating terminal (172). now,
It is assumed that the service A function 162-1 of the terminal b152 needs an information channel and requests a free information channel. The service A function 162-1 of the terminal b152 transmits a message including the information channel request command 221 (FIG. 22) to the transmission path 150 by broadcast (211 (FIG. 21)).
Terminal a151HBC function 161-1 that has received this message
The terminal and the terminal dHBC function 163-1 both search for a free information channel managed by themselves and return a response. At this time, terminal a
151HBC function 161-1 and terminal dHBC function 163
It is assumed that the management specifications of the information channel of -1 have the following contents.

(1) Information channel management specification by the terminal a151HBC161-1: It is checked whether the information channel number is in use in ascending order of the information channel number, and when there is a request for the information channel, the empty number found first is returned as a response. .

(2) Information channel management specification by the terminal dHBC 163-1: The use or non-use of the information channel is checked in order from the part where the pointer is currently present, and when the channel number reaches the maximum, the number starts from the first again. Check and return the first available number as a response.

In FIG. 23, it is assumed that black circles 230 and 237 indicate the positions of pointers for searching for an empty channel. At this time, it is assumed that the terminal b 152 has transmitted (211) the use request command 223 of the information channel 2 to the transmission line 150 by simultaneous broadcast. At the time of receiving this command, the information channel use management table statuses managed by the terminal a controller function (HBC function) 161-1 and the terminal c controller function (HBC function) 163-1 are respectively the status I shown in FIG. (231, 234). Both controllers have information channels NO. Since 2 indicates an empty state, a channel use permission command 224 is returned (212, 213), and the status of each information channel use management table shifts to state II (232, 235). At this time, in the terminal a controller function (HBC function) 161-1, the pointer for empty search indicates the management table of the information channel 1, and in the terminal c controller function (HBC function) 163-1, the pointer for empty search is the information channel. 3 shows a third management table. In this situation, it is assumed that the terminal d154 has transmitted (214) the channel request command 221 for requesting the information channel allocation to the transmission line 150 by simultaneous broadcast. When this command is received, the terminal a controller function (HBC function) 161-
1 indicates the management table of the information channel 1. Since the information channel 1 is in an unused state, the channel No. 1 that has designated the information channel 1 to the terminal d154 that has made the request. The designated channel use permission command 222 is transmitted (215). On the other hand, when the terminal d154 receives the channel request command 221 for requesting the information channel allocation, the empty search pointer of the terminal c controller function (HBC function) 163-1 indicates the management table of the information channel 3, The terminal d1 which has been requested because the information channel 3 is unused.
Channel No. 54 which designated information channel 3 for
The designated channel use permission command 222 is transmitted (216). At this time, the terminal d154 receives the permission to use the information channel 1 (215) and the permission to use the information channel 3 (216), and the terminal side has difficulty deciding which information channel to use. Yes, if the former information channel 1 is used, the terminal c
The situation 236 managed by the controller function (HBC) 163-1 of 153 differs from the situation of the actual system. If the terminal d154 uses the latter information channel 3, the status 233 managed by the controller function (HBC) 161-1 of the terminal a151 is different from the status of the actual system. There was a problem that the system could not be synchronized.

[0008]

As a countermeasure for solving the above problem, a conventional tool is used to check whether or not the terminal has the same controller function before connecting the terminal to the transmission line. Sometimes a terminal that has eliminated its controller function from the beginning is connected instead,

Embodiments of the present invention will be described below with reference to the drawings.

Two terminals a151 and c153 having a specific service function as controllers are connected to the transmission line 1
50 (see FIG. 16). As shown in FIGS. 5 and 6, the terminal a 151 and the terminal c 153 receive a message on the transmission line 150 and transmit a message on the transmission line 150.
It has a service function determination processing unit 52 that performs a service function determination process of the received message and transfers the message to each service function processing unit, and each of the service function processing units 53 to 56 as constituent elements. FIG. 5 shows a case where the service function activation control processing unit 50 takes a first form in which the service function activation control processing unit 52 is connected to the service function activation control processing unit 52. FIG. This is a case where the second mode in which the unit 50 exists is adopted. The difference between the first embodiment and the second embodiment of the configuration of the service function activation control processing unit 50 is that the first embodiment is configured to control information of all the service function control processing units 53 to 56 held by the terminal. A processing unit such as a memory is required as compared with the second embodiment. For the sake of simplicity, a second
Will be used. Further, as commands for control in the present invention, (1-a) 41 and (1-b) 42 relating to the first and second sequence examples, and (2-a) 43 relating to the third sequence example ~ (2-e) 47
(See FIG. 4).

Hereinafter, each of the first to third sequences will be described with reference to FIGS. 1 to 9, FIG. 15, and FIG.
Further, in the case of the HBS to which the above-described embodiment is applied, particularly in the case of HBC, an embodiment of interlocking with address control will be described. 1 to 3, the service A controller 161-1 of the terminal a151 is referred to as a service A controller 1 for simplicity, and the service A controller 163-1 of the terminal c153 is referred to as a service A controller 2 for simplicity. It is written. <First Sequence Example> When no other terminal is operating (see the sequence (1) in FIG. 1); the controller function 163-1 for the service A of the terminal c153 starts the service function in FIG. "Start instruction" notification processing unit 7 at the time of start of control processing unit 50
The command 41 shown in FIG. 4, which is started in step 1 and instructs the start of the service A function, is transmitted (11) to the transmission line 150 by simultaneous broadcast (FIG. 1). After that, the transmission path 15
Since the monitoring of the message from 0 is performed, and the operation instruction command 42 shown in FIG. 4 is not received from another terminal even after the lapse of a predetermined time (12), the service A controller function 163-
1 starts the process (13) (FIG. 1).

When another terminal is operating (see the sequence (2) in FIG. 1); the sequence shown in (2) in FIG. 1 is the same as that in the case where a controller having the same function is already operating on the network. This is a sequence when starting up. For example, while the terminal c153 is operating, the terminal a15
1 will be described. The service A controller function 161-1 of the terminal a151 turns on the power,
"Start instruction" when starting the service function start control processing unit 50
The command 41, which is activated by the notification processing unit 71 and instructs the start of activation of the service A function, is transmitted on the transmission path 150 by simultaneous broadcast (15) (see FIGS. 16 and 1 (2)). On the other hand, the service A controller function 163-1 of the terminal c153 receives the activation start command 41,
The “activation instruction” reception processing unit 72 (FIG. 7) is activated, and transmits the operating indicator command 42 (FIG. 4) onto the transmission line 150. As a result, the service function activation control processing unit 50 of the service A controller function 161-1 of the terminal a151 sends the operating instruction command 4 from the transmission path 150.
2 (16) (FIG. 1 (2)). As a result, the service A command function 161-1 of the terminal a151 stops the activation of the service function (17).

According to this embodiment, only one controller having a plurality of identical functions is provided on the network, so that the management can be synchronized and unified, and the communication can be automatically performed. Reduction leads to prevention of erroneous operation. <Second sequence example> As shown in FIG.
The service function activation control processing unit 50 of the third service A controller function 163-1 further includes an activation “operation instruction” notification processing unit 81 that transmits an operation instruction command 42 at fixed time intervals during activation. The service A controller function 161-1 of the stopped terminal a151
The service function activation control processing unit 50 further includes a stopped “operating instruction” notification reception processing unit 82. During the start-up, the “in-operation instruction” notification processing unit 81 sets a predetermined time interval T
, The operating instruction command 42 is broadcasted simultaneously to the transmission path 150
It is transmitted (21, 22 (FIG. 2)). The stopped "operating instruction" notification reception processing unit 82 of the controller function 161-1 for the service function A of the terminal a151 initializes the command reception waiting timer every time the operating indicator command 42 is received.

Now, if an error occurs in the service A command function 163-1 of the terminal c153 and this function is stopped (23), the terminal a service A controller function 161-1 executes the operating indicator command 42. The reception time-out is confirmed (24), and the activation-time "activation instruction" notification processing unit 71 is activated to activate its function (2)
5). The sequence after the activation is as shown in the first sequence example.

According to this embodiment, when a plurality of controllers having the same function exist on the network and only one of them is operating, an abnormality occurs in one of the controllers and the function cannot be provided. In this case, the system can be operated without stopping the function, and the restart process can be automatically performed by communication, so that the complexity of the manual transfer process can be reduced. <Third Sequence Example> As shown in FIG. 9, the third sequence example is based on the case where the terminal does not have the stopped “operating instruction” notification reception processing unit 82 shown in the second sequence example. This is related to a restart control process of a service function that has been stopped.

An error has occurred in the service A controller function 163-1 of the terminal c153, and the function has been stopped (3
1) (see FIG. 3). At this time, the service A processing function 162-1 of the terminal b 152 transmits (32) a request command for the service A function (for example, the information channel request command 221 shown in the conventional example) on the transmission path 150, and waits for a response. If there is no response even after the retry (33), the service A function activation request processing section 90 (FIG. 9) of the service function A control processing section 91 of the terminal b 152 starts the service A function activation processing. Service function activation request processing unit 9
In the case of 0, if there is no response to the service requests 32 and 33, an activation request command 45 (FIG. 4) for requesting activation of the service A is transmitted on the transmission line 150 by simultaneous broadcast. At this time, for example, two terminals, ie, terminal a
It is assumed that the service A controller function 161-1 of the terminal 151 and the service A controller function 164-1 of the terminal d have been stopped. The service function activation control processing unit 50 of the two functions that has received the activation request command 45 includes a suspended “activation request” reception processing unit 83 (see FIG. 8), and the processing unit 83 executes the activation request command. 45
A start request response command 46 as a response to the
152 to the service function A control processing unit 91 (3
5, 36) (FIG. 3). At this time, assuming that the terminal that has transmitted the earlier response is, for example, the terminal d154, the service function A control processing unit 91 of the terminal b152 determines that the terminal d154
(37) is returned to the service A function 164-1. And terminal d154
When the service A function 164-1 receives the activation request response confirmation command 47 within a predetermined time, the stop processing is released and activated (38), and the activation processing shown in the first sequence is started.

On the other hand, the service A function 1 of the terminal a 151
In the case of 61-1, the other terminal d154 before the fixed time elapses
(39), it is regarded that its own start request response command 46 has not been accepted, the start processing is terminated, and the stop is continued (30).
(FIG. 3).

According to the present embodiment, when a plurality of controllers having the same function exist on the network and only one of them is operating, an abnormality occurs in one of the controllers and the function cannot be provided. In this case, the system can be operated without stopping the function, and the restart process can be automatically performed by communication, so that the complexity of the manual transfer process can be reduced. In particular, according to the present embodiment, the load on the controller terminal (instruction during startup at a fixed time interval,
Confirmation of the instruction during startup) can be reduced. <Example of interlocking with HBC address control> HBS is a system to which the above sequence is applied.
In some cases, the range of the address value set in the self address storage unit 111 is determined by the function held by the terminal (see FIG. 11) (ET-
2101 Home Bus System Standards). Especially HBC
Is one in the system, and the address is 00H (1
01) (see FIG. 10). The HBS has a concept of a composite terminal, and one physical address has a plurality of functions. This shows exactly the system to which the present invention can be applied, but in this case, since there is only one address, the terminal is selected from those assigned to the functions held by the terminal. Now, the service function A of the terminal a151 is HB
Assuming that C and service function B are CTC and service function C is NT, the possible addresses of this terminal are as shown in FIG.
There are ten values 101 to 103-7 shown in (1) of 0 (see 113 in FIG. 11). Here, it is assumed that the terminal c153 also holds the HBC function of the service function A. At this time, since the HBC function cannot be started, such as when the terminal a is started later as shown in FIG. 1 (2), it is necessary to change the address of the other functions. Therefore, as shown in FIG. 10B, a new address mask table 114 is provided, and the service function activation control processing unit 50 causes the address mask table 11 to be provided.
4 and the address setting processing unit 112 are controlled to perform address masking or mask release (when the HBC function can be activated) (see FIG. 11). The address setting processing unit 112 rewrites the next address storage unit 111 with reference to the address mask table 114 and the settable address table 113.

FIG. 12 shows a service function activation control processing unit 5.
FIG. 7 is a block diagram for realizing an address change when the service function control processing unit 121 has 0.

FIG. 13 is a diagram showing a configuration example of the service function activation control processing section 50 shown in FIGS. 11 and 12. FIG. 14 is a diagram illustrating a configuration example of the service function activation control processing unit 50 illustrated in FIGS. 11 and 12. According to the present embodiment, in a system using a terminal in which the self address storage unit is configured by a nonvolatile RAM, unnecessary control is performed in automatic setting of an address at the time of starting when the power of the system is simultaneously shut down during system startup. Disappears.
