|This paper briefly described the systematic architecture of the online monitoring equipment for heavy metals，the method validation，the optimization of systematic procedures，the operational and maintenance cycle，and emergency warning functions. The online monitoring technology for heavy metals was applied in the early warning and monitoring of drinking water sources in Changzhou. The results showed that the monitoring equipment was relatively stable in measuring heavy metals such as Ni，Pb，As，Cd， Cu，and basically qualified the requirement for early warning and emergency. Through optimization of systematic procedures and exploration of remote control functions，this equipment fulfills the requirement for the unattended automatic monitoring. Preliminary application of the online monitoring technology in the early warning and monitoring of drinking water sources resulted in effective technological processes during early warning and emergencies，and added a safety barrier to the drinking water quality.
