FIG. 3 is a transmission data format of a peripheral device of the channel configuration information identification device of the present invention. FIG. 4 is a response data format of the central unit of the channel configuration information identifying apparatus of the present invention.

In FIG. 1, the channel configuration information identifying device includes a receiving channel 2 as a channel in which a central device 10 and an integer number of transmission / reception pairs of 1 or more are defined in the central device 10.
1A _{1 to} 21A _n , 21B _{1 to} 21B _n and transmission channels 22A _{1 to} 22A _n and 22B _{1 to} 22B _n (here, for example, the reception channel 21A ₁ and the transmission channel 22A ₁ form a pair). A plurality of peripheral devices 30 ₁ to 30 _n connected to each other are provided.

Here, a feature of the present invention is that each of the plurality of peripheral devices 30 ₁ to 30 _n sets a unique identifier of its own device in the peripheral device identifier data and transmits the peripheral device identifier through the above channel. The central device 10 includes a means 31 and a channel configuration table 12 for storing the channel configuration of the above channels, and a peripheral device identifier receiving means 11 for receiving the peripheral device identifier data from the peripheral device identifier transmitting means 31. Transmission / reception channel configuration identification means 13 for retrieving the contents of the channel configuration table 12 based on the identifier set in the peripheral device identifier data and allocating a unique identifier of the device to each peripheral device and registering in the channel configuration table 12. Set the channel number of the channel that received the peripheral device identifier data in the response data, and set the channel number via this channel. And a reply unit 14 to answer,
The peripheral devices 30 ₁ to 30 _n each include a completion confirming unit 32 that receives response data from the central device 10 and confirms the completion of processing.

The data format of the peripheral device identifier data is the header area 7 as the first header area.
1 and a command area 72 as a first command area,
A data format of the response data includes a header area 81 as a second header area and a command area 8 as a second command area.
2 and a channel number storage unit 83.

The operation of the channel configuration information identification device having such a configuration will be described. FIG. 2 is a flow chart showing the operation of the transmission / reception channel configuration identifying means of the central unit of the channel configuration information identifying apparatus of the present invention.

1 to 4, the peripheral device 30 ₁
With respect to the receiving channels 21A ₁ , 21 of the central unit 10.
It is assumed that B ₁ is connected and the transmission channels 22A ₁ and 22B ₂ are connected. Here, the receiving channel 21A
₁ and transmission channel 22A ₁ and reception channel 2
1B ₁ and the transmission channel 22B ₁ are a pair of a reception channel and a transmission channel, respectively. The peripheral device 30 ₁ uses the peripheral device identifier transmitting means 31 to set peripheral device data (for example, serial number) unique in the system as an identifier in the peripheral device identifier storage unit 73, and the peripheral device identifier data is connected to the connected reception channel. 21A ₁ and 21B
Send through ₁ .

In the central device 10, when the peripheral device identifier receiving means 11 receives the peripheral device identifier data, the contents of the peripheral device identifier storing portion 73 are referred to and the same identifier is registered using the transmission / reception channel configuration identifying means 13. The channel configuration table 12 is searched for whether or not the same identifier has already been registered for the received channel (S1). Here, if the identifier is not registered (S2), a unique identifier is assigned to the peripheral device 30 ₁ (S3), and if the identifier is registered, the corresponding identifier is stored in the channel configuration table 12 as the corresponding identifier. Register (S4). At this time, channels in which the same identifier is registered are considered to be connected to the same peripheral device. Here, the receiving channel 21A ₁ and the receiving channel 21
B ₁ receives data having the same identifier.

Next, the reply means 14 is activated to notify the completion of the procedure. The reply means 14 transmits the response data as shown in FIG. 4 to the corresponding transmission channels 22A ₁ and 22B ₁ . At this time, the reception channel number of the reception channel that has just been received is set in the channel number storage unit 83, and the data is transmitted via the corresponding transmission channel (that is, when the reception channel 21A ₁ receives the transmission channel 22A). ₁ is transmitted, and when it is received from the reception channel 21B _1, it is transmitted to the transmission channel 22B _1. )

When the peripheral device 30 ₁ receives the response data, the peripheral device 30 ₁ refers to the contents of the channel number storage unit 83 to determine which reception channel the response is to. In this example, the channel number storage unit 83 stores the receiving channel 21A ₁ ,
21B ₁ is set as related to the peripheral device 30 ₁ .

The operation has been described above for the unidirectional channel, but the same applies to the case of the bidirectional channel.
The only difference is that the central unit 10 responds to the received channel.

The above-described operation allows the channel configuration to be automatically recognized.

[0020]

As described above, according to the present invention, it is not necessary to define the configuration at the time of construction, and the configuration of the channel can be automatically identified and updated. There is an effect.
