A water quality alarm system and method based on Internet of Things. The system is characterized in that: when it is determined, according to on-site water quality data of a particular water quality monitoring station in a particular city, that the on-site water quality of the water quality monitoring station exceeds a standard, if it is calculated and determined that there is a target loudspeaker device (102), among registered loudspeaker devices in the city, from which the linear distance to position information of the water quality monitoring station is less than a specified threshold, a water quality alarm platform (101) sends by means of Internet of Things to the target loudspeaker device (102) an automatic alarm message including position information of the water quality monitoring station of which the on-site water quality exceeds the standard, and reports by means of Internet of Things to a flood control center station the position information of the water quality monitoring station of which the on-site water quality exceeds the standard; the target loudspeaker device (102) plays the automatic alarm message. The water quality alarm system and method can perform timely warning of water quality exceeding a standard, and ensure the water safety in the city.
