the control unit comprises a first acquisition assembly, a second acquisition assembly, a third acquisition assembly, a central controller, a monitoring controller and a wireless communication module;
the first acquisition assembly, the second acquisition assembly and the third acquisition assembly are respectively arranged at the output ends of the primary filtering unit, the secondary filtering unit and the final filtering unit;
the first acquisition assembly, the second acquisition assembly and the third acquisition assembly acquire data and send the acquired data to the monitoring controller through an internal bus, the monitoring controller processes and calculates the acquired data, the working condition of each level of filtering units is judged, the working effectiveness of each level of filtering units is evaluated in real time, the obtained data result is sent to the central controller, and the central controller is connected with an external mobile terminal through a wireless communication module to perform data interaction.
