Abstract

PURPOSE:To decrease the time required for transmission of the information and to save the circuit using fee, by transmitting plural types of information through just one dial calling. CONSTITUTION:When a warning, etc. occurs, the dialing is carried out to a warning receiving center. When this receiving center has an automatic incoming, the signals of 1,800Hz are continuously transmitted in twice. the answer signal is transmitted first to reset a circuit timer part 7 and then to stop the operation of a machine. the second signal of 1,800Hz is a command for transmission of the data. With this signal, the terminal number, various types of guard information, the end signal or the retransmission signal are transmitted from an information transmitting part 8. An error of the warning information is checked at the warning receiving center, and the correct data is decided. Then the third signal of 1,800Hz is sent back. A receiving timer part 9 is reset by the third signal. Thus it is decided that the transmission is all carried out in a correct way. In such way, the two types of guard information can be sent to the receiving center by just one dialing.
