GAS SUPPLY CONTROL SYSTEM AND METHOD THEREOF

摘要

The present invention relates to a gas supply control system and a method thereof. The system receives measurement guidelines of gas lines from a home gas meter, a district manostat, and an area manostat, receives the pressure, flow velocity, and flow rate of gas inside the piping between the district manostat and the area manostat from a first sensor, and receives the pressure and temperature value of gas inside the piping between the area manostat and the home gas meter from a second sensor, so that a control unit can control the pressure of the gas inside the piping when the pressure of gas inside the piping among the home gas meter, the district manostat, and the area manostat is not within the reference pressure value range. In addition, the gas supply control system can provide information on the gain or loss of measurement or information on gas leakage using the measurement information, and can provide information on the state of a piping network and a differential flow. Also, the gas supply control system allows a user to select a certain pipe to check the piping network analysis pressure value thereof while seeing the overall piping network diagram.
