PURPOSE: Continuous gas supply system and a remote monitoring control system are provided to continuously supply gas for replacement of gas container or filling gas when gas pressure is lower than a regular pressure and to sense gas leakage for shutting off gas supply by sensing. CONSTITUTION: A control unit(34) receives a signal from a pressure switch(27) in case of lower than a specific gas pressure as gas is consumed for a shut-off unit(12) to move a cock to a next position. A connecting pipe(14) is closed and gas is supplied to other connecting pipe(15) causing gas pressure of a supply pipe(16) to rise and an electric contact point of a pressure switch(27) to be connected. A gas container(18) joined with the connecting pipe(14) in the direction where gas pressure is lower is replaced or filled with gas. Preferably, for prevention of counterflow of gas to the lower pressure connecting pipe, a check valve is disposed so gas flow as to move in one direction. Moreover, a control unit(34) is connected with an address transmit device(38) for sending a signal to a gas supplier to replace the gas container. If gas pressure is lower than a specific pressure even though moving the cock, the cock is moved more than plural times and generating an alarm.
