Communication is possible even using a 2 kbps analog modem. Further, in the case of supporting ISDN, the public line modem 26 may be replaced with a TA or DSU.

Here, an example of the configuration of the server control unit 23 will be described with reference to FIG. FIG. 2 is a configuration block diagram illustrating an example of the server control unit 23. As shown in FIG. 2, the server control unit 23 receives stock information from the host 1, receives command information from the public line network via the incoming call control unit 24, and sends the stock information to the incoming call control unit 24. , A RAM 42 for storing the received stock information, a ROM 43 for storing software for controlling the server control unit 23,
When the stock information is received via the serial communication circuit 41 according to the software stored in the OM 43, the stock information is stored in the RAM 42, and when the command information is received, the command information is indicated. The stock information of the brand is read from the RAM 42 and the serial communication circuit 4
1 and a control circuit 44 for outputting to the incoming call control unit 24 through the control unit 1.

The server control unit 23 includes a control circuit 44
A maintenance console may be provided to set the operation of the server. In this case, if a non-volatile memory (EEPROM or the like) for storing the contents of the setting is provided, even if the power is turned off once, the setting contents are retained. And convenience can be improved. Note that a buffer is provided between the nonvolatile memory and the control circuit 44.

Further, the RAM 42 and the ROM 43 include
It is conceivable that a buffer is provided as shown in FIG. In this way, by making the buffer a buffer that can be read and written at a high speed, for example, stock information input momentarily can be stored regardless of the access speed to the RAM 42, and the processing can be performed at high speed. it can.

Here, the stock information stored in the RAM 42 is specifically as shown in FIG. FIG.
FIG. 4 is an explanatory diagram showing an example of stock information stored in the RAM 42. As shown in FIG. 3, in the RAM 42, information on a brand code, a brand name, the open price, the high price, the low price, the closing price, four prices of the stock of the brand, and the previous day ratio are stored for each brand. Are stored in association with each other.

Although only the above information shown in FIG. 3 is stored here, information such as the amount of work may be stored. Furthermore, it is conceivable that the information is calculated by the control circuit 44 if possible. This has the effect of providing more advanced information regardless of the communication capacity.

Here, with respect to the incoming call control unit 24,
This will be described with reference to FIG. FIG. 4 is a configuration block diagram illustrating an example of the incoming call control unit 24. The incoming call control unit 24
As shown in FIG. 4, one line is sequentially selected from the k connected lines at regular time intervals, and the selected line is connected via a public line modem provided corresponding to the selected line. A line control circuit 51 for receiving password information and command information and transmitting and outputting stock information and the like; a multiplexer 52 for sequentially selecting lines by a time-division multiplexing method; and a clock circuit for measuring a fixed time for selecting a line 53
According to the ROM 54 storing software for controlling the incoming call control unit 24 and the software stored in the ROM 54, a password matching process is performed, and if the user is not an authorized user, the line is disconnected. If the user is an authorized user, the server control unit 2
3 and a RAM 56 and a non-volatile memory 57 for storing information necessary for execution of the processing of the control circuit 55.

Here, the incoming call control unit 24 transmits and outputs stock information and the like via a public line network by a line control circuit 51, a multiplexer 52, and a clock circuit 53 by a time division multiplex communication method. I'm going to keep it.

Further, as shown in FIG.
A transmission buffer and a reception buffer may be provided between the control circuit 51 and the line control circuit 51 to temporarily store information to be transmitted and output. By doing so, the control circuit 54 can be used because the communication capacity of the public network is relatively low.
And the delay of the processing of the control circuit 54, the received command information and the like are lost, and the user is forced to retransmit the command information. There is an effect that convenience can be improved.

Next, the operation of the present system will be described. The host 1 transmits and outputs the ever-changing stock information to the base server 2 at the base via the dedicated line, and the base server 2
Server controller 23 updates and stores the stock information.

Specifically, the stock price data (stock price of one stock, five stock prices) from the host 1 in real time is 0.3 to
The voice data modulated to the analog signal of 3.4 kHz is transmitted to the dedicated line modem 21 of the base server 2 via the dedicated line, and similarly, the stock price data (the stock price of each brand)
As soon as a new update occurs, it is sequentially transmitted.

The leased line modem 21 demodulates stock price data (voice data) and outputs it to the server control unit 23. At this time, the stock price data has been converted to digital data. The server control unit 23 stores the stock price data, and when the stock price data of the same brand is received next, if there is no error when comparing with the previously stored stock price data (the stock price of one brand, five stock prices), The stored stock price data is used as the determined stock price data. This is due to the fact that the same data is transmitted from the host 1 in principle three times for the same brand in consideration of the occurrence of errors and the like. However, depending on the traffic volume of the transmission data, only one of the updated brand code and five values may be transmitted.

On the other hand, the user makes an application for receiving a service to a company or an organization that manages the host 1 or the base server 2 and pays an enrollment fee. The password will be sent to you.

Here, the user is a general investor who manages stocks, and in order to receive the service, it is necessary to become a user through the above procedure. In addition, the user is charged a service fee for each usage time separately from the line fee, the enrollment fee and the service fee are paid to the TSE and the base, and the service fee is collected in the same manner as dial Q2. Things.

Further, the user can use a personal computer 3 with a public line modem installed with communication software.
Prepare 2 The communication software may be general commercially available communication software (such as WTERM).

Then, when the user uses the service of the present system for the first time, he calls the base server 2 using communication software (off-hook and dials the telephone number). When the connection to the base server 2 is completed, real-time stock price data acquisition software (utility software) is downloaded. After downloading, disconnect the line (on-hook). Since the downloaded software is compressed, decompress it.

In this manner, software (utility software) constantly updated in the base server 2
Is stored, the user can obtain software in which a so-called bug has been corrected or the like by a simple operation, and there is an effect that the reliability of the system can be improved.

Then, the user uses the personal computer system 3 to call the base server 2 with communication software. When the line is connected, start the decompressed software (stock price data real-time acquisition software).

Then, the incoming call control unit 24 of the base server 2 receives the call, starts password verification processing, and when it is confirmed that the user is a legitimate user, inputs command information from the user. And a command request process of transmitting stock information corresponding to a specific brand in accordance with the command information.

The password collation processing means that the password request from the base server 2 is transmitted to the personal computer system 3.
The personal computer system 3 inputs the password sent with the application consent form. If the password is correct, the base server 2 transmits an authentication confirmation. If the password is incorrect, the user will be requested to re-enter the password. However, this re-input request is made up to three times, and if it is erroneous any more, the base server 2 disconnects the line for effective use of the line.

The command request processing is specifically the following processing. First, the base server 2 transmits a message “What brand price data should you select?” To the user's personal computer system 3 and waits for command information input from the user.

Then, the user inputs command information (brand code or brand name) for requesting stock information of a specific brand from the personal computer system 3, and the command information is transmitted to the base server 2 via the public line network. Then, the incoming call control unit 24 of the base server 2 receives the command information.

Then, the incoming call control unit 24 outputs to the server control unit 23 an instruction requesting stock information of the specific brand specified by the command information, and the server control unit 23 outputs the stock information corresponding to the specific brand. get. Then, the server control unit 23 outputs stock information corresponding to the specific brand to the incoming call control unit 24, and the incoming control unit 24 transmits and outputs the stock information to the modem that has received the command information for selecting the stock. Is what you do. Thereafter, when receiving the service termination request, the base server 2 disconnects the public line.

Then, the personal computer system 3 receives and displays and outputs the stock information, so that the user can see the stock information of a desired brand. Here, as shown in FIG. 5, the screen displayed and output by the personal computer system 3 corresponds to a table format in which the stock code, the stock name, the four prices, and the information on the previous day are included in the received stock information. It is thought that it was attached. FIG.
FIG. 9 is an explanatory diagram illustrating an example of a screen displayed and output by the personal computer system 3.

When the command information is transmitted and output to the base server 2, the brand name or the brand code is entered in the text input box (a) of FIG. 5 and the return key is pressed to transmit and output the command information. It is conceivable to make sure that

By adopting a graphical interface as shown in FIG. 5, convenience can be improved.

Further, the installer of the base server 2 adopts a so-called dial Q2 system of NTT in a public line network for receiving a call from a general user.
Pay-as-you-go billing for general users can be made.

According to this system, a user can use all stock information of listed brands distributed on a dedicated line for a personal computer system at home or the like (a portable telephone and a portable personal computer may be used on the go). Since stock information can be browsed and batch processing is not performed, stock information can be transmitted in real time with a delay of at most 100 milliseconds.
