Abstract

PURPOSE:To apply the titled transmitter to the normal transmission possible for frequency multilexing like 200 bps and to improve the performance of the transmitter, by preparing an MODEM having a higher speed than the normal transmission speed to a modulation and demodulation device MODEM transmitting and receiving series data via a communication line. CONSTITUTION:A signal is inputted from a computer and a terminal device to of an information transmitter of a slave station 1, the input signal is converted into the series data at 200 bps modulators MOD 2, 3 for CH, and transmitted to a communication line 11. This data is demodulated at 200 bps demodulators DEM 6, 7 for each CH of an information transmitter 5 of a master station 5. This master station 5 is provided with a 200 bps MOD8 for CH incorporating a control code and a high speed MODEM10, and the slave station 1 is provided with a 200 pbs DEM4 and a high speed MODEM9. Further, in case of emergency, the MODEM is switched to the MODEMs 9, 10 having a transmission speed higher than 200 bps automatically, allowing to attain the transmission speed variable type information transmitter with sufficient flexibility.

Conventional Information Transmission 1iIifrill Since the configuration is nτ as described above, even if a special emergency situation such as a line failure occurs, there is no choice but to send information from the slave station of the information transmission device to the master station of the transmission device in n1 steps. However, it had disadvantages such as slow transmission speed.

Therefore, the present invention is designed to eliminate the conventional loud noise as described above, and when a special situation requiring high-speed transmission occurs, another transmission command signal is input from the outside. It is an object of the present invention to provide an information transmission device that allows for quick switching to a MODEM with a faster transmission speed and allows rapid transmission.

An embodiment of the present invention will be explained below with reference to the drawings.

The operation of the present invention will now be briefly described. Computers, terminals, etc. are input to the information transmission device slave station 1.

And 200bps for C0m, MOD3 is 1 and the inner row data is nlI! It is sent to the I-line line 11. Then, the information transmission device master station 5 receives χ.
