Registered in the, based on the correspondence information registered in the ID number registration means, multiplexes the received data from the control device and transmits to the general exchange,
It is characterized in that multiplexed reception data from the general exchange is separated and transmitted to the control device.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment of a system to which the present invention is applied. The first to third controllers 11 to 13 of the remote exchange 1 having different functions are connected to the connection lines 4a to 4a, respectively.
It is connected to the data relay device 2 via 4c. The data relay device 2 is connected to the central office switch 3 via the multiplexed data line 5.
Connected to the data controller 34,
Are connected to first to third terminals 31 to 33 corresponding to the first to third control devices 11 to 13, respectively.

The data relay device 2 includes control device connection circuits 21 to 23 connected to the connection lines 4a to 4c and transmitting and receiving data,
A processor 25 for processing data, a memory 26 for storing data, a multiplexed data transmission / reception circuit 27 having a buffer 27a and connected to the multiplexed data line 5 for serially transmitting and receiving multiplexed data; A data bus 24 interconnects the connection circuits 21 to 23, the processor 25, the memory 26, and the buffer 27a of the multiplexed data transmission / reception circuit 27.

 Next, the operation will be described.

At the first time when each of the control devices 11 to 13 and each of the control device connection circuits 21 to 23 are connected via the connection lines 4a to 4c, identification of which control device is connected to which control device connection circuit is performed. FIG. 2 is a flowchart of the process of the data relay device 2 at this time.

When the control device connection circuits 21 to 23 enter an operable state, they enter a state of waiting for input data from the connection lines 4a to 4c. on the other hand,
When each of the control devices 11 to 13 recognizes the connection of the data relay device 2, an ID number for device type identification assigned in advance to each of the control devices 11 to 13 is transmitted until a response from the data relay device 2 is received. Keep doing. First control device 11
The control device connection circuit 21 that has received data from the
The received data is transmitted to the processor 25 through the processor 24, and the processor 25 performs a process of recognizing the received data (steps 100 to 100).
2) When the ID number is normally detected (Y in step 102),
Recognizing that the control device connected to the control device connection circuit 21 via the connection line 4a is the first control device 11,
The ID number is registered in the memory 26 (step 103). After registration, the processor 25 transfers the response data to the control device connection circuit 21 via the data bus 24, and responds to the first control device 11 via the connection line 4a (step 104). After receiving the response, the first control device 11 stops transmitting the ID number and starts transmitting and receiving control data. After that, the processor 25 uses the data input to the control device connection circuit 21 to generate an ID for device type identification.
It is considered that control data transmission / reception starts from the point in time when data other than the number is received (Y in step 105) (step 10).
6) The data is accumulated in the area of the memory 26 for the control device connection circuit 21 for the first control device 11.

The other control devices 12 and 13 and the control device connection circuits 22 and 23 perform the same operation, and the control device connection circuits 2 and
Data will be stored in the 2,23 area.

When a certain amount of data is stored in the memory 26, the processor 25 attaches an ID number registered in the memory 26 to the head of the data stored in each area, multiplexes the data, and transfers the data to the buffer 27a. The multiplexed data transmission / reception circuit 27 sends the data transferred to the buffer 27a to the general exchange 3 via the multiplexed data line 5.

The multiplexed data input from the central office exchange 3 to the multiplexed data transmission / reception circuit 27 via the multiplexed data line 5 is stored in the buffer 27a, and the processor 25 separates the multiplexed data in the buffer 27a and outputs the separated data. The ID number for device type identification added to the head of is compared with the ID number for device type identification registered in the memory 26, and the matching control device connection circuit in which the matching ID number is registered is checked. Then, the data obtained by removing the ID number from the separated data is transferred, and the data is transmitted to the corresponding control device.

Even if the combination of connection between each of these control devices 11 to 13 and each of control device connection circuits 21 to 23 is changed, the same operation as described above is performed, and processor 25 determines which control device It can be recognized whether or not it is connected to the device connection circuit.

As described above, the first to third terminals 31 to 31 of the central office exchange 3
Each of the devices 33 performs data communication with each of the first to third control devices 11 to 13 of the remote local exchange 1 to perform remote control and monitoring.

〔The invention's effect〕

As described above, the present invention transmits an ID number for device type identification from a control device and recognizes the control device in correspondence with the control device connection circuit of the data relay device that has received the ID number. There is no need to fixedly assign a control device connection circuit to the controller, and the combination of connections between the control device and the control device connection circuit can be set arbitrarily, preventing connection errors during connection work and improving work efficiency. There is.
