1. A method of controlling a carbon compound manufacturing system,
the system comprising:
a recovery unit configured to separate carbon dioxide from a supply gas containing the carbon dioxide;
a conversion unit configured to convert the carbon dioxide supplied from the recovery unit into an intermediate compound;
a synthesis unit configured to synthesize a carbon compound using the intermediate compound supplied from the conversion unit;
an emission unit configured to discharge the supply gas;
a first flow path for supplying the supply gas to the recovery unit, the first flow path connecting the recovery unit and the emission unit;
a second flow path connecting the recovery unit and the conversion unit;
a third flow path connecting the conversion unit and the synthesis unit;
a first detector configured to measure a flow rate of the supply gas flowing from the emission unit to the recovery unit through the first flow path to generate a first data signal;
a second detector configured to measure a flow rate of the carbon dioxide flowing through the second flow path to generate a second data signal;
a third detector configured to measure a value of voltage or current supplied to the conversion unit to generate a third data signal; and
an integration controller,
the method comprising:
generating the first to third data signals and transmitting the first to third data signals to the integration controller; and
collating measured data in the first to third data signals with a plan data corresponding to the measured data by the integration controller to generate a first control signal for adjusting an operation condition of the recovery unit, a second control signal for adjusting an operation condition of the conversion unit, and a third control signal for adjusting an operation condition of the synthesis unit by calculation processing when a value of the measured data is outside a request criteria range of a value of the plan data.
