1. A water quality monitoring system, comprising:
a plurality of sensors for respectively sensing a plurality of environmental parameters and respectively outputting a plurality of sensing signals that respectively correspond to the plurality of environmental parameters;
a plurality of actuators configured to change the plurality of environmental parameters; and
an embedded system connected to the plurality of sensors and the plurality of the actuators, the embedded system comprising:
a storage module configured to store a plurality of normal parameter ranges that correspond to the plurality of respective environmental parameters;
a data collection module connected to the plurality of sensors and configured to receive the plurality of sensing signals;
a data analysis module connected to the storage module and the data collection module, wherein the data analysis module is configured to determine that the plurality of sensors corresponding to the plurality of sensing signals are abnormal in response to the environmental parameters being outside the normal parameter ranges, determine that the plurality of sensors corresponding to the sensing signals are normal in response to the environmental parameters being within the normal parameter ranges, and output a determination result accordingly; and
a control module connected to the data analysis module and configured to control the plurality of actuators in response to the determination result indicating that the plurality of sensors are normal, and to output a warning signal in response to the determination result indicating that the plurality of sensors are abnormal;
wherein the plurality of environmental parameters comprise temperature, pH value, oxidation-reduction potential, and/or salinity.
