Alarm control method for measuring sulfur-carbon ratio of ship exhaust gas

The invention discloses an alarm control method for measuring the sulfur-carbon ratio of ship exhaust gas, the whole alarm content is divided into three parts: an analyzer module, a CO2 module and a PLC module, and the analyzer module designs a plurality of groups of alarm contents corresponding to SO2 detection; the CO2 module designs a plurality of groups of alarm contents corresponding to CO2 detection; and the PLC module designs a plurality of groups of alarm information for the alarm content of the whole system corresponding to the PLC part. According to the invention, the functions of PLC alarm, analyzer alarm and CO2 module alarm are integrated, so that the stability and reliability of the CEMS are greatly improved; through a unified alarm rule, problems caused by differences among different monitoring instruments are solved. And when the CO2 module gives an alarm, the whole analyzer closes sampling and enters a maintenance state, so that the safety is ensured. 本发明公开了一种测量船舶废气硫碳比的报警控制方法，将整个报警内容分成三个部分：分析
