The line was left connected, and the line was disconnected from the terminal device when processing on the terminal device was completed.

Problems to be Solved by the Invention In such conventional examples, once a line is connected from the terminal device side and processing is started, that line is occupied until the processing of that terminal device is completed, and characters are The number of data input/output ports on the information system center equipment side was the maximum number of simultaneous support for that system.

Means for Solving the Problems In order to solve the above-mentioned problems, the character information system of the present invention, as a center device, has an external data input terminal that connects with the character information data supply destination, and an external data input terminal from the external data input terminal. a data import unit that imports character information data; a data memory circuit that stores character information data from the data import unit; a transmission circuit that transmits commands and data to the terminal device; a receiving circuit for receiving data, a terminal management memory circuit for storing data transmission processing to the terminal device and a state of the terminal device according to commands from the terminal device, and data accumulation information from the data memory circuit; a transmission management circuit that receives commands from the reception circuit and terminal status information from the terminal management memory circuit, exchanges IDs with the terminal device, sends commands to the terminal device, and manages data transmission; This is a character information system having a center device equipped with a data input/output port for connection with the terminal device.

According to the above-described configuration, the present invention manages the operation status of the terminal device once connected in the terminal management memory circuit of the center device, and when all the data in response to the request from the terminal device has been transmitted, the operation status is managed from the center device side. The line is disconnected and the output port of the center device is opened for other terminal devices to increase the number of devices that can be serviced simultaneously when viewed from the terminal device side.

Embodiment FIG. 1 is a circuit configuration diagram of a center device in a character information system according to an embodiment of the present invention, FIG. 2 is a configuration diagram of a terminal management memory circuit in the center device, and FIG. 2 shows a configuration diagram of terminal status flags in .

In FIG. 1, 101 is an external data input terminal, 1
02 is a data acquisition unit; 103 is a data memory circuit;
104 is a transmitting circuit, 105 is a receiving circuit, 106 is
Terminal management memory circuit, 107, transmission management circuit, 108
is a data input/output port.

The operation of the center device of the character information system of this embodiment configured as described above will be explained below. Character information data from a character information data supply destination such as Tokoyamisha is taken in by the data importing unit 102 via the external data input terminal 10i via a public line, and is then input to the data memory circuit 1.
03 is stored in the area to be saved.

Here, a terminal device sends an I/O signal to one data source (capo) 108 for confirming the partner station via the network.
When a D (label) exchange request is input, the receiving circuit 105
After inputting the terminal ID to the transmission management circuit 107 and determining whether connection is possible, it is stored in the terminal ID storage area of the terminal management memory PI 106, and at the same time, the ID of the center device is transmitted from the transmission circuit 104 via the network. The data is returned to the terminal device (D exchange ends.

Data is sent from the terminal device via the network.
) 108, it is reproduced by the receiving circuit 105, enters the transmission management circuit '#1107, and based on the character information data storage information from the data memory circuit 103, the data is sent from the transmitting circuit 104. Character information data is transmitted to the terminal device via the input/output port 108.

Also, here, if the data request command from the terminal device indicates that all necessary data has been captured on the terminal device side, that is, the normal data sending flag is set in Fig. 3. At times, the commands reproduced by the receiving circuit cause the terminal management memory circuit 1 to
060 normal data sent flag is set, and
The transmission management circuit 107 transmits a line disconnection command to the currently connected terminal device via the transmission circuit 104 and the data port 108 to disconnect the line.

Further, when update data is input manually via the external data input terminal 101, it is stored as update data in the data memory circuit 103, the update information is managed by the transmission management circuit 107, and the terminal management memory circuit 106 normally sends data. If the completed flag is set and the other flags are cleared, the terminal device determines that the data can be updated. Then, the terminal device is dialed using the terminal dial number in the terminal management memory circuit, the line is connected from the center device side, and it is determined by ID exchange whether update data of this system can be received. For example, the transmission management circuit 107 sends stored character information data in the form of a pointer to the transmission circuit 104, which transmits it to the terminal device via the data input/output port 108, and stores it in the terminal management memory circuit 106. Set the update processing flag. Furthermore, if the terminal device is not in a state where it can receive update data, such as when the terminal device is powered off or is connected to another system on the network, the update prohibition flag is set, and from then on, the terminal device is not allowed to receive update data again. Update data will not be sent unless a line connection is made from the terminal device side.

As shown in FIG. 2, for example, if the transmission management circuit now receives update data, it will sequentially search the terminal status flags in the terminal management memory circuit, and if the terminal ID is rMOOIJ and the terminal status flag is "02". state, i.e. the third
If only the normal data sent flag is set in ②, it indicates that data update processing is possible for this terminal device, and data update processing is started based on the terminal dial number. .

In addition, in the terminal IDrMOO2J, the terminal status flag is in the state of "01", that is, if only the update processing prohibition flag is set in Fig. 3, it indicates that data update processing cannot be performed for this terminal device. , the update process is interrupted and the process moves on to searching for the next terminal status flag.

As described above, according to this embodiment, by providing a terminal management memory circuit that manages the operating status of the terminal equipment, the center equipment side can grasp the status of the terminal equipment, cancel unnecessary line connections, and If so, you can also make a line connection from the center device.

Furthermore, as long as only the electrical and physical communication regulations are met, text information data can be received from multiple sources using line switching on the public line even if there is only one data importing unit. The service becomes possible by converting the data into an internal format defined between the center device and the terminal device within the data import unit.

In addition, the multiple data input/output ports of the center device are capable of both sending and receiving, and when performing update processing, a port that is not in use at that time is used; however, one of the data input/output ports is For update processing only,
By using it in conjunction with other data input/output ports, it is possible to increase the efficiency of data update service processing.

As described in detail, according to the present invention, the limited data input/output ports for connecting terminal devices of the center device can be effectively utilized, and its practical effects are great.
