Abstract: Remote monitoring and controlling system that made LPC2132 as controller chips was used to monitor power supply voltage， current， temperature and pressure of motor and pump， and other parameters. These parameters were used as a basis for estimated working condition of pump and motor. In order to protect safety of motor and pump， motor should be stop immediately if working condition of exception appeared. Anomalies were transmitted to manager by remote data transmission and remedial measures were taken in time. The whole system achieves not only remote data transmission but also remote control. Systems were used in many places； results showed that control system could be operated steadily and reliably. So it has a good application prospect and promotion value.
