The lower computer controls the motor control circuit of the sewage pump to work, the force control configuration software is communicated with the DDC by using a LonWorks network, the state of an I/O interface of the DDC is monitored, and the state is transmitted to the computer in the form of a variable value, and is used and processed by the upper computer. The sewage pump motor control circuit comprises a sewage pump motor M, a contactor KM1, a relay K2 and a relay K3, wherein a wiring terminal of the sewage pump motor M is connected with a frequency sensitive resistor RF1, the contactor KM1 and a breaker QF1 in series and then connected with a zero line and a fire line, the zero line and the fire line are respectively connected with an input end of an AC-DC conversion circuit and an input end of the relay K2 and an indicator lamp L1 through the breaker QF2, and an output end of the AC-DC conversion circuit is connected with an input end of a breaker QF3 and outputs 24V voltage; the live wire is connected with one end of a frequency sensitive resistor RF1 through a breaker QF4, the other end of the frequency sensitive resistor RF1 is connected with one end of a manual/automatic transfer switch SA and one end of a relay K1 respectively, the other end of the manual/automatic transfer switch SA is connected with a zero line after being connected with a normally closed switch SB0, a normally open switch SB1 and a contactor coil KM1 in series, the contactor KM1 is connected with two ends of the normally open switch SB1 in parallel, the other end of the relay K1 is connected with one ends of a signal lamp XD1 and the contactor coil KM1 respectively, one end of the relay K3 is connected with the live wire, and the other end of the relay K3 is connected with the zero line through an indicator lamp BJ;

The left side of fig. 2 is a schematic diagram of the strong electric control cabinet, which is an electric control circuit of the sewage pump motor. The system principle is as follows: the sewage pump motor M has two control modes of manual operation and automatic operation, and is controlled and switched by the manual/automatic change-over switch SA, when SA is in the closed position, the KM1 coil is electrified when the start button SB1 is pressed, the main contact is closed, the sewage pump can be started, the KM1 coil is electrified when the stop button SB0 is pressed, the main contact is disconnected, and the sewage pump is stopped. That is, SB1 and SB0 are buttons for controlling the start and stop of the sewage pump in the manual state; when SA is in the open position, the two manual buttons SB1 and SB0 are not active, and whether the KM1 coil is electrified or not is determined by the normally open contact of the relay K1, and whether the normally open contact of the relay K1 is closed or not depends on DO1 output of the DDC, namely, is determined by the DDC program, so that under the state, we consider as automatic control of the sewage pump. In addition, the L1 lamp is a lighting lamp, and the BJ indicator lamp is a sewage pump fault alarm lamp.
