The invention discloses a warning method and a
warning system for filter elements of water purifiers. The warning method includes steps of acquiring
water quality parameters, receiving the
water quality parameters by the aid of a
microcontroller and counting and monitoring states of the filter elements of the water purifiers according to the
water quality parameters; receiving the states, which are monitored by the
microcontroller, of the filter elements of the water purifiers by the aid of a subserver and forwarding the states of the filter elements of the water purifiers to a remote
server;receiving the water quality parameters, finished water improvement values, filter cumulative time and total filtered water volumes of each water purifier by the aid of the remote
server, acquiring water
hardness parameters according to received data, searching
filter element service life algorithms from preset
filter element service life
algorithm tables and issuing the corresponding
filter element service life algorithms to the
microcontroller. The filter element service life algorithms correspond to the water
hardness parameters. The warning method and the
warning system have the advantagesthat the filter element service life algorithms for each water purifier can be updated by the remote
server in real time; water quality change in different regions and different seasons is monitored and is combined with the use states of the filter elements, the filter element algorithms can be updated in real time, and accordingly the service lives and use of the filter elements of the water purifiers are close to practical use conditions.
