Comparing the pressure value of the current period with a pressure standard, and pressurizing or depressurizing the pipeline according to the comparison result;
obtaining the actual power P of the water supply equipment according to the pipeline pressures f1 and f2 at the starting pressurizing and depressurizing time e1 and the current time e2 Feeding of ；
And comparing the actual power with the rated power, dividing the water supply equipment into normal equipment and fault equipment according to the comparison result, and generating corresponding equipment alarm information for the fault equipment.
2. The analysis system for risk prevention and control of an underground pipe rack in a city based on big data according to claim 1, wherein the monitoring module monitors the level of the pipe rack and judges whether sedimentation has occurred according to the monitoring result comprises:
the middle section of the pipe gallery is provided with a laser transmitting unit and a laser receiving unit, laser is transmitted to the laser receiving units of two adjacent pipe galleries through the laser transmitting unit, and the laser transmitted by the laser transmitting units of the two adjacent pipe galleries is received through the laser receiving unit;
taking the drainage direction of the pipe gallery as the positive direction, taking the current pipe gallery as a starting point, taking the next pipe gallery along the drainage direction as the front, taking the last pipe gallery along the reverse drainage direction as the rear, dividing the pipe gallery into a horizontal state or a sedimentation state according to the quantity and the direction of laser which can be received by the laser receiving unit, and generating corresponding sedimentation alarm information for the pipe gallery marked as the sedimentation state.
3. The analysis system for risk prevention and control of an underground pipe gallery based on big data according to claim 2, wherein the process of feeding back the alarm information to the staff by the feedback module comprises:
setting a feedback unit, sending various alarm information to a staff end through the feedback unit, and processing by the staff according to the corresponding alarm information;
and setting a navigation unit, automatically generating a navigation route according to the geographic position in the alarm information, and navigating the staff to the corresponding place.
