JPS58191039A - Method and device of display at sight for stock price information - Google Patents

Abstract

PURPOSE:To simplify the operation and to avoid a misoperation for display of the stock price information, by displaying the information which is fed in a prescribed sequence and in time series only when it is coincident with a desired issue code that is previously fed. CONSTITUTION:A desired issue code and its display position are both fed from an issue selection input device 20 and stored in a non-volatile memory 16 via a control circuit 13. A power supply is applied to a CPU11, and the correspondence between control and issue codes is written to the control memory 13 from an external memory 21 and then fed to a converting circuit 14 together with the storage contents of the memory 16. Then a control code and the information on the display position are shifted to a checking circuit 15. The circuit 15 stores these code and information temporarily in the memory 13 only when the control code given from a communication circuit 2 is coincident with the control code given from the circuit 14 and then sotres them in a display memory 18 along with the display designated position for display 19. When an issue desired for display is to be changed, the memory 21 is replaced. In such a way, the operation is simplified for display with no malfunction.

Description

[Detailed Description of the Invention] This relates to an information transmission and display system in which a plurality of pieces of information consisting of control codes and data are arranged in time series and transmitted one-way from an information signal transmission device to a terminal device over a single communication line. It is. More specifically, it is a stock price information reporting system, in which stock price information generated at a stock exchange is converted into information signals having the above configuration by the CPU of the information item sending device on the exchange side, and these information signal units are The signals are sent out over a pair of communication lines in chronological order in the order in which they occurred.

This communication line is repeatedly branched by a branching device along the way to transmit the information erasure to multiple terminal devices.

On the other hand, the terminal device receives more information signals than it can display, and selects information from among them.
3 is a communication line that performs one-way transmission, 3 is a branching device, and 4 is a terminal device. The present invention relates to improvements to this terminal device.

The conventional terminal device receives the information signal from the communication line shown in FIG.
The display is performed by a circuit consisting of a control memory 8, a display memory 9, and a display device 10. The number of information that can actually be displayed reaches approximately 960 in total, including all of the stocks listed on the first section sent out by the stock exchange and a portion of the stocks listed on the second section. This incoming information is once written into a control memory within the control device, and only the brands required by each terminal are transferred and displayed on the display memory within the control device.

In the early days when this system was implemented, it was not possible to write the desired brand into the control memory using the terminal device, and a factory-written read-only memory (ROM) was inserted into the control device as the display brand memory. Ta. However, recently it has become possible to write the desired brand into the display brand memory from a brand selection input device (keyboard) connected to the control device.

However, there is a problem here: In other words, since the signal sent from the information signal transmitting device is composed of a control code and the stock price data of the stock of that control code as described above, the person operating this terminal device (mainly securities personnel) can directly receive the signal. The brand is specified using an unrelated control code.

However, since securities managers always use stock codes (also called securities codes) in their daily transactions, they must find and input the control code from this stock code using the control code and stock code correspondence table. There wasn't.

The present invention has been made to solve these problems, and it extracts and displays a desired stock with a stock code that is not included in the information signal from among a series of received stock price information, and It has a program that prevents the selection function from stopping even if a brand that is not included in the system is specified by mistake. This will be explained in detail below.

FIG. 6 shows the circuit configuration of the terminal device, where 1 is a control device, which includes 12 to 18 described below.01
2 is a demodulation circuit for information signals sent through a communication line; 13
is a control circuit, which includes a conversion circuit 14 that converts the brand code into a control code based on the correspondence table between the control code and the brand code, and an information signal in which the control code converted by the conversion circuit is sent through the communication line. It has a built-in check circuit 15 that checks whether or not it is included in the . Reference numeral 16 denotes a display brand memory, which is a non-volatile memory such as a core, and the stored contents are unrelated to whether the power is connected or disconnected. 17 is a control memory, and 18 is a display memory. Reference numeral 19 denotes a display device, which usually consists of 4 to 16 screens. 20 is a brand selection input device, and 21 is an external memory having a correspondence table between control codes and brand codes.Next, the operation of this terminal device will be explained. First, a brand desired to be displayed and its display position are input using the brand code used in general securities transactions from the brand selection input device. This input passes through a control circuit, and the brand code and its display position are written into the display brand memory. Since this display brand memory is a non-volatile memory such as a core, the stored contents are maintained regardless of whether the power is turned off or not, unless a deletion command is input from the brand selection manual device.

When the power switch of the control device is turned on, the correspondence table between the control code and brand code stored in the external memory is written to the control memory, and then input to the conversion circuit along with the stored content of the display brand memory. The information on the control code and its display position is transferred to the check circuit. The check circuit compares the control code of the information signal sent through the communication line with the control code of the signal sent from the conversion circuit, and if they match, writes this signal to a specified location in the control memory. , if they do not match, the next signal is processed one after another without writing this signal into the control memory. On the other hand, when the data for each brand is sent through the communication line, the controller for that brand is sent.

- Once written to the control memory by the V code,
Only for brands whose display position is specified, data is transferred to that display position. The information developed at the designated position in this way is transcribed into the display memo IJ and displayed on the display device.

Note that in the above-mentioned system, part of the control code may be changed once a year due to omission of brand specification or additional specification. In such a case, vC will replace the correspondence table between AfJ external memory control codes and brand codes to a correspondence table with new control codes, and after replacing the entire external memory, all subsequent operations will be performed within the control device. It is extremely easy to operate as it can be done automatically.

As described above, according to the present invention, a person who handles a terminal device can operate it using only the brand code that he/she uses in his/her daily work. Not only is this unnecessary, but also no erroneous shift 55 occurs due to this conversion operation, which is extremely effective in practice.
