Electric water heater magnesium rod consumption condition assessment method, system and server

The invention discloses an electric water heater magnesium rod consumption condition assessment method, system and server; the method comprises the following steps: the server obtains a mobile number or position information of a mobile terminal; the server obtains a mobile terminal user location region according to the mobile terminal mobile number or position information; the server obtains water quality information of the user location region, and determines the life of the electric water heater magnesium rod according to the water quality; the server obtains a present time and a starting time of the electric water heater magnesium rod, and calculates a usage time period of the electric water heater magnesium rod according to the present time and the starting time; the server determines remaining time of the electric water heater magnesium rod according to the life and usage time period of the electric water heater magnesium rod, and pushes the information to the mobile terminal. The method allows the user to check the electric water heater magnesium rod usage conditions; after the electric water heater magnesium rod is consumed, the user can timely replace the electric water heater magnesium rod, thus reducing water leakage conditions caused by a corrosion inner container.
