Description

[Title of the Invention]

A communication system and method for transmitting data simultaneously with voice calls over telephone lines.

【Technical field】

The present invention relates to a communication system for transmitting data from a computer or the like using a telephone line at the same time as a voice call, and a method therefor.

[Background Art]

Conventionally, a method has been widely used in which data terminals such as a computer and a word processor are used together with a modem to exchange data with each other using a telephone line. Some modems have a function that can transmit data simultaneously with voice signals for calls, and some modems with voice were used. It was only used to a very limited extent due to the need to use its software. The second thing is that personal computer viewers are now widespread, and various software for using them are available on the market. Most of them are: Computers and other devices are often used by running them. Some of them include communication software, and some are dedicated to communication. The software was created mainly with the function of transmitting the existing data and the newly created data together with the file data transmission function. However, it has not been possible to get the most out of a modem with voice:

DISCLOSURE OF THE INVENTION

Examples of conventional data communication using various software, including communication software and communication software, mainly for file data transmission. As an example, we used a modem to transmit electronic circuit diagrams, architectural drawings, and other file data to other computers and other data terminal equipment via telephone lines, and received the data. Using the data sent, the terminal outputs text, drawings, etc. on a terminal device monitor (VDT), printer, plotter, etc., and it is unclear from seeing this. If you need to confirm a part or need to confirm it, call the person who sent the file data and just call and explain the contents; It is often very difficult to accurately explain only the detailed position of a drawing, correction method, etc. in words using the power method used in There were many cases where the contents were not transmitted unless I went out.

In such a case, a data terminal such as a computer connected through a telephone line is connected to a software terminal running on the terminal by using a voice-enabled dem that can transmit data simultaneously with a voice call. Regardless of the content, that is, if various softwares that have been conventionally marketed and do not include communication software are used as they are, the same data terminal is used for both computers and other data terminals. to execute the same Zoff Bok Uea one whose content drawings and full Airude evening such documents, the operation for using the second Zoff Bok wear, for example, performs an input by operating the keyboard force ^1, Mausuko emissions Bok When you move the roller or perform tablet input, these operations will cause you to perform your own operation or input to the terminal device that you operated. In addition, if the same operation can be performed on the terminal device on the concession side connected through the telephone line as if the same operation was performed, both terminals can be operated when both terminals are operated. The terminal device performs exactly the same operation. Naturally, the same screen is displayed on the monitor (video display tarminal: VDT) connected to both terminals. become.

If you use a modem with voice as the modem, you can talk at the same time while watching the same screen display, so even if you are actually far away, The situation is the same as talking with a drawing or the like placed on the screen. 'The mouse controller or keyboard operation performed on both sides allows you to monitor the terminal device you are operating (.vido di splay tarminal: VDT ) By moving the mouse controller while watching the screen, the other monitor (video display tarminal: VDT) Λ The mouse cursor also points to the same position on the same display screen. Location indications, which have been a problem with conventional methods, can also be performed accurately and easily, and corrections and changes to drawings, characters, numerical values, etc. can be performed simultaneously on both terminals if one of them is operated For, It is not necessary to go out to the other party in a timely manner. A very effective system can be configured for the shortage of human resources and problems at any time. It is a method that makes it possible.

When configuring the system according to the present invention, a cheek terminal device such as a computer: A modem with voice is added, and as a software layer, both the main software and the main unit are usually connected to the modem, and the output used by connecting the modem, for example, n S-?, C For example, a keyboard with a function to output the input data from the keyboard and mouse controller input device is required. Software is not available on the market and new software must be created.

Here's how to solve this problem, including:

[Means to solve the problem] ''

(Α) A modem with voice is used for the modem part of the system, and the contents of the data to be transmitted simultaneously with the voice signal for communication are executed by a motor terminal device such as a computer. The keyboard connected to the terminal device to use the device includes the output signal cheeks of input devices such as a mouse controller and a tablet console. '

(Ii) Do not connect output signals of input devices such as keyboard, mouse controller, tablet, etc. directly to the data terminal device so that commercially available software can be used as it is. First, input to the adapter composed of hardware, perform certain processing in the mapper, and then input the output signal of the second adapter to the input terminal of the 1000 terminal equipment. At the same time, the second data is transmitted to the other party by the modem unit, and conversely, the data sent from the other party has a winding function to be input to the input terminal of the terminal device. Data terminals such as convenience stores, etc., operate independently and output output of input devices regardless of the software running on them. Made it possible:

[Brief description of the drawings]

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described. FIG. 1 shows a conventional method using the present invention.

_ — This shows the computer in the case of configuring a system that can use the software as it is, the input device such as a keyboard controller, a keyboard, and the like, and the mirrored state of a mochi with sound. Here is the diagram:

-As can be seen from Fig. 2, all input devices such as a keyboard, mouse controller, and tablet that are normally connected directly to the computer are connected to the adapter. The reason for such a connection is'

(1) The operation of the main unit and the operation of the input device can be performed independently, so that the software that can be executed and used on the main unit can be used as it is with the first-class commercial software. Like

(2) When data transmission is performed by a modem using an analog line, keyboard and mouse control cannot be performed because data transmission cannot be performed at high speed like a digital line.

—To perform data signal processing so that data such as errors and tablets can be transmitted most efficiently.

First _c to perform For more explanation for the secondary things, and a description will be given independent of the operations of the co-down computer body operation and the input for the equipment of (1), keyboard and mouse score down Controller, Tablet Tsu If you connect the devices directly to the computer, the output signal data of each input device can be executed by software on the computer itself! In order to extract the changes in the data that has been input and the changes in the data while operating the mouse controller to the outside of the computer, it is necessary to use ί¾; If you want to take out the data, you can't take out the data unless you install a 'software' to output the data to RS-232C in the software to be executed on the computer In the second state Bodo Ya mouse con Bokuro retrieve the output data, such as one error operation depends entirely Nico Npyu Ichita is made to run on the body Zoff Bok Uea.

On the other hand, as shown in Fig. 1, the output signals of input devices such as a keyboard, a mouse controller, a tablet, etc. are applied once every time, and the output signal data of these input devices are output. If you use the method of inputting the symbol data to the computer after reading the data, the keyboard, mouse controller, evening shutter, etc. can be used regardless of the contents of the software of the computer. You can read the output signal and send the data to the modem with sound. Can be input, including the data sent from the user side, so the software and computer running on the computer itself have no restrictions whatsoever. It will be possible to use commercial software such as software as it is: Next, we will explain how to efficiently transmit the data in (2):

At present, most of the software on the market places importance on ease of use, so most operations for using each software are performed by the mouse controller or tablet. in the manner performed by the position input device of bets like, _c operations keyhole I where those made to the necessary minimum has become mainstream

For this reason, in the present invention, a force that is indispensable to respond to these position input devices is required; various software can be provided by connecting the mouse controller to the computer body in a normal use manner. When using the key, the computer main unit is connected to the mouse controller from the interface circuit to which the mouse controller is connected.

In order to detect and read the moving direction, moving distance, and switch state of the camera, repeated interruptions of about 10 [mS] to 30 [mS] during period II are performed on each computer. It's usually done by Le Timer. It is a typical personal computer in Japan to find out how large the data of the mouse controller interface circuit that the computer is reading at the second time! \ ^: Taking the PC-980 series of EC as an example, the mouse interface used in the second PC_980 series is one-line interface. The length of the heater of the heater handled by the IC circuit; the length of this bit is 12 bits in the X direction, 12 bits in the Y direction, and 32 bits including the switch state. If the long data is transmitted by a start-stop synchronous modem, which is the most common method currently used, without any processing, it is estimated how many repetition cycles can be transmitted. In general, the bit length of data transmitted using a modem is 7 or 8 bits. If an 8-bit data length is transmitted, the start bit is used in the start-stop synchronization method. And the stop bits are added), the actual bit length of each one is 11 bits, Even if the data read from the controller's interface circuit is transmitted in sequence, the content of the mark received on the receiving side is the data in the X direction of the mouse controller. Since it is not known whether the data in the Y direction is O, it is necessary to incorporate data to determine this and transmit it. Actually, each child of the keyboard is also included in the data to be transmitted, so it is necessary to add at least about 40 bits to be able to judge this. Including the start and stop bits for data transmission and reception, the time required to repeat and transmit about 100 bits of data is the repetition cycle time: For example, I 20 O bps When a modem with a transmission rate is used, the repetition period takes 83.3 [ms].

This usually takes about 10 times as long as the PC-9800 series reads the data of the mouse-in-face circuit every approximately 8.3 [ms]. If the transmission time is long, the responsiveness when operating the mouse controller will be reduced, and the movement itself will be very inconsistent.

In the present invention, in order to solve the second problem, signal data of a mouse controller, a keyboard, a tablet, and the like are transferred to each interface circuit A, B, C inside the adapter shown in FIG. After reading the data and performing data processing so that these data can be transmitted efficiently, this data is sent to the modem unit with voice and transmitted overnight.

To explain this processing method, Fig. 2 shows the data sent to the modem unit with voice after data processing (Fig. 1D) and the data received from the modem with voice training. Fig. 1 shows an example of the format of Fig. 1 (D 'in Fig. 1). To explain Fig. 2 in detail, Fig. 2-11: Data D1 following the start bit ~ D8 represents the count data value in the X direction, D8 represents + or 1 in that direction: D9 is the parity bit for the bit indicating the switch state and is D10 (Fig. The bit that indicates the state of the switch in Figure 9), D9 in Figure 12 (bit that indicates the state of the left switch), and DI 0 (the bit that indicates the state of the right switch) This is a bit that is added after R.

FIG. 2 shows the code data 1 and D'12 for judging the contents of the data. For example, when both of these two data are ¾-, the mouse controller 1 In the λ 'direction (チ), it represents one night, only D12 represents the mouse controller, and only D11 represents the keyboard data. If determined, the receiving side can reliably determine what data was sent from this code data. Similarly, Fig. 1-2 shows D1 ~ following the start bit! ) 8 or the mouse controller The data value in the direction of OY is indicated, D9 is the state of the left switch, and D】 0 is the state of the right switch. D11 and D12 are the data. It is a code. Figure 13 shows the start bit following the start bit. I) Go to I). 1) is the bit that represents the key board. D9 and D10 are spare bits. You can also enter mosquitoes. Dl 1 and D 1 2 are the data representing the overnight code _

In Figs. 1 and 2, the count of the mouse controller is 1000 bits; the X direction and the Υ direction are both 8 bits. The force is two-thirds of the data length of the controller interface circuit in comparison with the data length; The control section in the figure always detects the signal state of each interface circuit (I / F-A), (I / F-Β), and (I / F-C). In a keyboard interface circuit, the presence or absence of a key input is determined by a tough "letter interface circuit (usually, the RS-232C1 uses a mouse control to determine whether a signal has changed or not. In the controller interface circuit: A change in the input signal is detected.

If there is no key input, including the key board in Fig. 2-13, send the message for one night, move the mouse controller, or press the mouse button unless the switch button is pressed. Since the input signal of the interface circuit does not change, in the case of 2, the data sequence of Fig. 2 is not transmitted. That is, when the mouse controller and the keyboard are not operated, no data is transmitted. In the control section, the control section sends the data sequence only when there is a change without sending any data.

Since a data code is added to each data column, it is possible to determine which data is sent in random order (Γ). Use the system according to the present invention. In this case, it is more appropriate to give a higher priority to the transmission of the mouse contact data than the keyboard data in actual use.

In this case, when the keyboard input and the mouse controller input are detected simultaneously, the data transmission of the mouse controller is performed first, and the keyboard input is performed in order to avoid the delay. The keyboard circuit has several keys in the interface circuit, and after the data transmission of the mouse controller has been completed, the keyboard data in the "one. If you do control to send, t:

Next, the data length of the mouse controller data is explained. As written, the count data value of the mouse controller interface circuit is the force read at 12 hits each in the X and Y directions; and the mouse controller interface circuit. Each time data is sent once, the counter is cleared and the count data value is reset to zero. Since the actual force data value obtained by the movement of the controller is reduced, the length of the mouse control port data that needs to be transmitted is also reduced, and the length of the data is reduced. In, it is possible to transmit the bit representing the movement amount of the mouse controller by 8 bits.

In Fig. 1, both the tablet and the mouse controller are connected.However, the tablet and the mouse controller are both devices for position input, so they are usually connected to each other. The software is operated using either the keyboard or the mouse.In the above explanation, the explanation was made using the keyboard and mouse controller. The same process can be performed even when using a tablet.The difference between a tablet and a mouse controller is that the tablet is an absolute position input device, whereas the mouse controller is a relative position input device. It is a device. What is the difference in actual operation? When operating both computers connected via telephone lines, when using a mouse controller that is a relative position input, both computers are connected. Move the mouse cursor position of the software running on the computer at least once to the origin (0, 0) on the software window, and move the mouse cursor position of both computers at least once. In contrast, a tablet that is an absolute position input device does not require the following:-When data signal processing is performed by the above-described method, a mouse controller is required. The repetition period required by a 1200 bps modem to transmit this data is about 25 [ms], including the start and stop bits. And when you are using, ho: or operation of the same feeling can be achieved. -Output signals (I / F-A), (IXF-B), and (I / F-C) in Fig. 1 are Α ', Β', and C ', respectively. b (usually RS-232C). Connected to one input terminal c of the mouse controller.This signal is input at the same time as input to the transmission data input Tx of the modem with voice; By sending to Pyu-Yu, Nu? The transmission of each child between the two views can be exactly the same.- The same equipment is connected to the other side connected via the telephone line, and the data sequence shown in Fig. 2 is not When sent, the Onoyoshi-attached module outputs the reception cheek to .D ', and within the adapcou on the receiving side, the contents of each child are discriminated from each child's coat, and the data is determined. Evening can be sent to the corresponding I / F circuit (1 _ or 1?-ー or I / F-C) and output. It is possible to make the computer perform the same operation: The modem with voice is shown as being embedded in the adapter in Fig. 1, but a single modem with voice can be used. It is possible to use a full-duplex system or a half-duplex system if the transmission and reception timing is taken into consideration. If a modem with voice can be used regardless of its type and method, if the handset is a headset, headphone, or mobile phone, more comfortable operation may be possible. _r the bracts to two fire can

In the conventional method, data communication is performed using a modem, and in order to view the same screen, various image data are transferred as file children. However, in this case, the modem only transmits the file overnight, and after the file transmission is completed, it does not transmit the message at all. : On the other hand, in the system according to the present invention, even after the end of the transmission of the image data, the data is continuously operated in the data communication state until the end of the communication so that the data of the computer or the like can be obtained. The difference from the conventional system is obvious in that the terminals operate in the same way at the same time.

Also, in the present invention, in order to be able to use all the software without modifying the conventional software, the functions that the software lacks are not included in the hardware. The system can be configured by adding an adapter, and all the processes and methods within the two adapters can be performed by software: '

In the case of Z, the adapter is the force that is no longer needed, and the adapter is the one that replaces the hardware with 'noft-air', and the form of the communication system is: The example of the data format shown in Fig. 13 "13" is an example that is easy to explain, and any data format can be used for efficient data transmission. The format Can also be used. "

[Industrial use P possibility]

As described above, if a system using the present invention is configured, even if it is actually a remote place, communication can be performed using the two systems to be at the same place. It can be set to the same state as that of a variety of industries, such as electricity, electronics, machinery, and construction, so it is very effective for various meetings and home work of engineers engaged in these jobs. It is a system that can be configured and can be used in other fields c
