The tap water remote pump room monitoring system mainly monitors, controls, and alarms the running status of the city tap water remote pump room. It can also collect real-time data of each remote water meter in a centralized manner. Solve the remote monitoring problems of water supply companies.
System structure diagram and function introduction The system has temperature sensor, flow meter, current transformer, contactor, infrared alarm and other equipment. The following explains in order:
1. The temperature sensor uses a patch-type temperature sensor, which is directly attached to the surface of the pump body to measure the temperature of the pump body and realize the function of temperature over-limit alarm;
2. The flowmeter is provided by the user, and the requirement is an intelligent flowmeter, which directly communicates with the monitoring controller through RS232 to exchange data;
3. The current transformer measures the current value of each phase of the pump, and transmits the data to the data center to realize the real-time detection of the current of each phase and alarm according to the set value;
4. The monitoring controller controls the action of the pump's AC contactor to realize the remote switching action of the pump, and judges the current start and stop status of the pump according to the state of the AC contactor to determine whether the current pump can be started;
5. The infrared alarm is mainly to judge the illegal intrusion alarm in the pump room, to prevent illegal man-made operation in the pump room.
