Abstract

PURPOSE:To change freely a data displaying method which a terminal body has, and an operating method of picture selection, etc., by providing a serial transmitting function on a terminal equipment of CAPTAIN. CONSTITUTION:A new routine is processed by providing a serial transmission converting circuit 20 on a terminal body 11. That is to say, whether serial data from the outside should be processed or neglected is decided, and when it has been recognized that the serial transmission processing is necessary, the processing is shifted to the next routine. As for this routine processing, data for operating a CAPTAIN terminal is received, and the terminal body 11 executes the processing of remote control and a remote control receiving part 19. Also, the next routine executes the processing of data to be sent to various external displays and an operating terminal equipment. Moreover, the next routine detects an end flag from in the CAPTAIN processing and the serial transmission processing routine. When the end flag is effective, the processing advances to the next routine, the connection of the CAPTAIN is cut, the end of the processing operation is informed to various external displays and the operating terminal, and the equipment is held until the terminal body 11 is operated in the next time.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a captain terminal device that receives and processes captain data sent through a telephone line.

<Conventional technology> An example of the configuration of a conventional captain terminal is shown in FIG.

The terminal main body 1 has a telephone line 2 (a modem 3 is interposed in the middle),
A display device 4, a remote control 5, a printer 6, etc. can be connected, and captain data is selected by the remote control 5 and displayed on the display device 4. It is also possible to copy the data displayed on the display device 4 onto the printer-6.

In the above example, operation input to the terminal main body 1 is performed using the remote control 5. The display device 4 is a CRT, and R
It is connected by means of F, Video, or R-G-B signals. The pattern information portion of the display data is printed out to the printer 6 by a method such as outputting it to the printer 6 side.

As mentioned above, conventional captain terminals can use one or more types of input/output methods, but this is a function that the terminal body 1 itself originally has, and when adding new functions, the terminal body 1 This cannot be easily achieved without improving itself.

<Object of the Invention> In order to eliminate the above-mentioned drawbacks, the present invention provides a serial transmission function that is not present in the conventional captain terminal.
The purpose is to make it possible to freely change the data display method, screen selection, and other operation methods of the terminal itself, thereby making it easy to add functions.

<Embodiment> FIG. 1 is a block diagram showing the configuration of a terminal main body in an embodiment of the present invention.

The terminal main body 11 includes a CPU (central processing unit) 12, a program ROM/work RAM 13, a captain data import operation data sending circuit 14, a display memory readout/
write circuit 151 display memory (e.g. RAM) 16;
It consists of a display data conversion circuit 17, a printer output circuit 18, a remote control receiving section 19, and a serial transmission conversion circuit 20.

12 to 19 are also provided in a conventional terminal main body.

The remote control receiving section 19 receives the key data sent from the remote control 5 (6th [i1 reference)]. The CPU 12 is programmed with a data processing method for the remote control receiver 19 in the program ROM/work RAM 13, so it processes the data in the remote control receiver 19 and performs appropriate processing such as displaying and sending the orbit signal to the captain center. Let's do it. Data from the captain center is processed by the CPU 12 through the captain data import/operation data output circuit 14. The processed data is stored in the display memory 16 via the display memory read/write circuit 15. Then, the display data conversion circuit 17 converts the stored processed data into displayable data (RF multiplied signal, Video signal,
R-G'-B signal, etc.) and output. The signal output from the display data conversion circuit 17 is sent to the display device 4 (sixth
(see figure). Printout is performed by sending out only the display pattern in the data stored in the display memo 'J16 from the printer output circuit 18.

The newly added serial transmission conversion circuit 20 is connected to a data bus (in this case, the CPU bus) 21, and allows data to be sent and received from an external device through a serial transmission path 22. That is, this includes the display memory read/write circuit 15, display memory 16, display data conversion circuit 17, remote control receiving section 19, and remote control 5 (
This is a circuit for receiving functions similar to those shown in FIG. 6) from an external device, and has functions such as display and input/output of operation data.

FIG. 2 shows an example of a system configuration when various external devices are connected to this terminal main body 11.

The display device 4, remote control 5, printer 6, etc. can be connected to the terminal main body 11 as in the conventional example shown in FIG.

Here, a display/operation terminal device (A) 23 , a display/operation terminal device (B) 24 , a display/operation terminal device (
C) 25 , a display/operation terminal device (D) 26 , and other display/operation terminal devices 27 can be connected. For example, the display/operation terminal device (C) 25, the display/operation terminal device (D) 26, the remote control 5, the remote control receiver 1
It has the same function as 9, and the two are connected by an infrared remote control signal or the like.

The processing in the terminal body 11 is as follows.

FIG. 3 shows a flowchart explaining the process.

a is a captain process, which is a conventional general process. b, c, d, and e are new processing routines resulting from the addition of the serial transmission conversion circuit 20 to the terminal body 11, and b examines the presence or absence of data sent through the serial transmission conversion circuit 20, and Determine whether to process or ignore the serial data. This includes various external display/operation terminal devices 23 to 2 as shown in FIG.
7 is connected, it is determined whether the data sent is for the captain terminal, and since some data is ignored even if it is for the captain terminal, this determination is made in routine b. When it is recognized that serial transmission processing is necessary in this routine b, the processing moves to the next routines c, d, and e.

C is a receiving processing routine for data sent from the outside through the serial transmission path 22, and data for operating the captain terminal is mainly received. This data transmission allows
Terminal body 11, conventional remote controller 5 and remote controller receiver 19
It is possible to perform the same processing as previously performed using . Since only one terminal device among the various external terminal devices 23 to 27 shown in FIG. 2 can be accessed from the terminal body 11, the data d is sent with an identification code attached thereto, which is data for one terminal device. The data includes screen control data, pattern data, code data, key data, etc. necessary for display.

e is a routine for detecting an end flag from the captain processing and added serial transmission processing routines similar to the conventional routine; if the end flag is valid, processing f is performed. f is a termination processing routine, which disconnects the connection to the captain center and connects various external display/operation terminal devices 23 to
This is a routine that notifies the terminal 27 that the current processing operation has ended and waits until the terminal main body 11 is operated next.

In the data transmission processing routine of d, one of the external display/operation terminal devices 23 to 27 to which the data is transmitted receives and stores the transmitted data, and also processes or processes the transmitted data or the stored data arbitrarily. etc., and can be displayed in a desired operation and display format on this terminal device.

In addition, for the captain's terminal body 11, the external terminal device (for example, the external display/operation terminal device 23 in FIG.
27) is multi-functional, the captain's terminal main body 11 can be used as a database for a part of the multi-functional external terminal device.

This makes it extremely easy to use when accessing many databases in the future by requiring only one terminal device, and the captain terminal can be operated and displayed in the same way using this multi-functional terminal device. For example, when creating a comprehensive information system in the home, the serial transmission line 22 is installed in the home as a home panel, and the captain's terminal body 11
It is very convenient to connect a multifunctional terminal device to this home bus and configure it as a workstation.

FIG. 4 shows an example of the configuration of an external terminal device. As shown,

and a CRT 33, a circuit 34 for various operations such as key operations, and a conversion circuit 35 for serial transmission connected to the serial transmission path 22. This external terminal device is mainly used for display and operation. but,
By connecting the extended function circuit 37 to the CPU module 36, it is possible to optionally add new processing to expand the functions of the terminal. In other words, in the latter case, many functions are added to the captain processing function itself.

FIG. 5 is a flowchart explaining the operation of a multi-functional terminal device, and due to the multi-functionality, normal common processing, captain function processing and other functional processing g+l+j
etc., and many processes can be performed by one terminal device.

However, the external terminal device for the captain's terminal main body 11 is not limited to the above-mentioned ones, and can be applied as long as it can at least transmit and receive data to and from the captain's terminal main body 11.

<Effects of the Invention> As described above, the present invention has a serial transmission function in the captain's terminal body, and the display method and operation method can be freely changed outside the terminal body, and the functions of the captain's terminal can be improved. can easily be added.
