DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application-1 The present invention relates to a data transmission system for transmitting data collected by a data terminal device to a central receiving device at a remote location using a telephone line. 1 noru.

Conventional Structure and Its Problems FIG. 1 shows a system diagram of this type of data terminal device using a telephone line and a remote center receiving device. When data terminal device 1 automatically connects to the center device and sends data, data terminal device I! Starting from 1lffn1 and 1? If the telephone 3 is not in use, the network control section of the data transmission device 2 seizes the telephone line 5 based on the dial information of the center and sends a dial signal to the exchange l1j4 of the central office. The exchange 4 selects the line of the center equipment and sends a calling signal (16H2) to the line A. This is connected to the network 11 of the data receiving device 6 at the center. When the l control unit detects this, it captures the line, the data receiving device 6 outputs a connection signal to the data processing device PI 7, and the data processing device 117 sends a response signal to the line. When the data transmission device 2 detects this, the collected data from the data terminal device 1 is automatically transmitted. When the data processing device 2-ill 7 finishes receiving the data, it sends out a Trl and response signal. When the data transmission device 2 detects this response signal, it is configured to give a signal for opening the line to the data terminal device 1 (i'-data transmission arm im2). 1. Conventionally, the upper structure of the terminal side of the system 7 of this scale has been constructed as shown in FIG. That is, the data terminal device 1 is connected to the modulation/demodulation device 8 and the σ network control device 9.

The data terminal device 1 sends the activation code d3 and the rental dial full information [(Network control I device 9 operates and dials the line 5 to 11itlil!shi, phase ¥-, and after the other party answers, the modulation/demodulation device 8 is activated. Data from the data terminal device 1 is transmitted to the line 5 via the line 5.

However, in contrast to 4T, this conventional data converting device has each function in a German-style '4A' format.
Requires physical space and lacks economics;
Or the dialing information of the center is on the data terminal; a!
However, the current situation is that the data terminal device 1 has drawbacks such as complicated functions.

A microprocessor is provided with a network control function, a modulation/demodulation function, a Daicel signal generation function, and a Daicel signal generation function. In addition to integrating control functions using a processor and other devices to achieve miniaturization, the data terminal device can be simplified, and data from the data terminal device can be sent to the center receiving device via a telephone line. 1.Description of an Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 3 and 4.

Figures 3a and 3b show the external appearance of a data transmission device according to the present invention. On the housing 10 are an operation keyboard 11, an input data and operation mode display section 12, a power switch 13, a power indicator lamp 14, a line usage lamp 15, and a communication lamp 1.

From the back of 0, there is a telephone line connection cable 18, power supply: 1
- code 19 is output and there is C. A terminal 20 for connecting a line and a telephone is connected to the cable 18.

Furthermore, as shown in Figure 3, the back of the housing 10 is equipped with a connector 21 for connecting to the data terminal device 1, and a converter 22 for switching the telephone line between the telephone side and the device side. -It has a type structure.

FIG. 4 shows the configuration of the device housed inside the housing 1O. 23 is a network control section, 24 is a modulation section for transmitting and receiving data, 25 is a dial pulse generation section, 2G is a boolean full signal generation section, 27 is a control section including a microphone [prohizza] and memory, 28 29 is a connection interface unit with the data terminal device 1; 29 is a power supply unit; 3
0 is a part of the monitor that drives the monitor speaker 17.

Here, when the power supply section 29 operates and the designated power supply voltage is supplied to each section, the microprocessor is operated according to the program stored in the program memory of the control section 27, and the initial setting input is performed on the display section 12. Display the current mode. Using the keyboard 11, set the call conditions [dialing signal method O call presence/absence, number of retakes, dial number, center response method] using the control section 27, and display the display section 1.
Check in step 2. When the initial settings are input, the control unit 27
displays on the display unit 12 that it is waiting for data input from the data terminal device 1. When the data terminal device 1 is connected to the connection interface section 28 and the transmission start signal (E r< ) to the device becomes A, the control section 27 gives a line connection signal to the network control section 23 . The network control unit 23 is the telephone 3
The network control unit 23 automatically detects the presence or absence of a call signal from the other party and automatically (detects, eventually L) the line 1 when it is not in use. line capture,
I;: Detects this, and outputs the dial pulse creation section 25 or the bush dial f^ bow creation section 2G with the dial pulse creation section 25 or the dial f^ bow creation section 2G according to the initial setting dial signal type, and outputs the dial pulse or signal from the creation section 25 or 26. A push code signal is sent to line 5.

When the line 5 is connected to the center receiving device and the other party responds, the response signal (DR) is turned on, and the line from the control section 27 to the network control section 23 is connected to the I/I adjustment section 24. ! Ru. The display section 28 displays that the dial mode is in effect during the dial A full, and displays that the mode is in the communication mode after the other party responds. At this time, the line usage lamp 15 and the communication lamp 16 are also turned on. When the response signal (DR) is turned on, the data terminal device 1 automatically performs data communication with the η center receiving device through this device. When the communication is completed, an outgoing activation message @ (
ER) is turned off, the control unit 29 changes the display unit 12 to display the input mode again, and lights up the line use lamp 15 and the communication lamp 16. If the center receiving device does not respond even after calling for a certain period of time, the control unit 27 calls -11, the network control unit 2
3 to open the line, and after a certain period of time has passed, re-transmission operation begins. If the center does not respond within the initial set number of re-transmissions, an alarm sound is output through the monitor speaker J17 on the monitor part 3O.

According to the data transmission device of the present invention, network control functions, modulation/demodulation functions, dial number setting functions, dial signal generation functions, etc. are all controlled by a control section comprising a microprocessor or the like. As a result, the following effects will occur.

- Since the network control and modulation/demodulation functions can be integrated, it is much simpler than the conventional system in which the modulation/demodulation equipment and the network control unit are configured and connected separately.

■ The operating status can be easily seen on the display.

■Dial numbers can be easily set and changed using the keyboard and display, and the dial information is provided in the data transmission device, so there is no need to complicate the functions of the data end = 8-floor device.
