The intelligent platform terminal supports the access of a mobile phone and a PC terminal, and maintenance personnel can know the working state of the equipment at any time, so that the daily operation and maintenance are facilitated.
The intelligent platform terminal can be accessed by a mobile phone and a PC terminal. The staff can be at any time the equipment running condition of the lifting pump station of remote monitoring, 1 arbitrary equipment of remote operation. The aim of unattended operation on site is achieved;
the system adopts an unattended design, and workers can remotely operate pump station equipment and remotely monitor the running state of the equipment. The operation efficiency is improved, and the manpower is saved.
The intelligent platform terminal can read local weather forecast information in real time, and the intelligent control mode of the system is adjusted according to weather changes:
1) when the rainwater is not available, the water quantity of the water collecting tank is less, and when the water level does not exceed 1/4 highest water level, each water pump adopts various intermittent working modes. The intermittent time is automatically adjusted within 1-24 hours and is linked with weather forecast. The intelligent platform terminal analyzes the working mode of each water pump according to the local weather meteorological data shared by the network, issues an instruction to the PLC, and the PLC automatically adjusts and controls the running time of each water pump according to the pre-programmed working mode scheme. The specific operating modes are shown in the following table:
2) after entering a rainy season, the water level of the water collecting tank changes in real time, and particularly when the water level exceeds 1/4H (the highest safe water level is represented by H), the system automatically exits the intermittent working mode. The system is no longer under the linkage control of weather forecast. The PLC realizes the linkage control of each water pump according to the water level change of the water collecting tank.
When the water level exceeds 1/4H, the system automatically starts 1 water pump, after 10 minutes of delay, the system automatically starts 1 water pump again when the water level is found to be still rising, and the double pumps work simultaneously; after delaying for 20 minutes, if the water level is still rising, the 3 rd water pump is automatically started, and the 3 pumps work simultaneously; after delaying for 30 minutes, if the water level is still rising, the system automatically puts 4 pumps into operation. To ensure that the water level in the sump cannot exceed the maximum safe water level H. After the water pump is added to be put into operation, delaying time is up, and when the current water level falls back, the system automatically keeps the number of the current working pumps to work continuously; when the water level drops to 1/8H, all pumps are deactivated.
3) And the start and stop of the lifting water pump and the interlocking control of the butterfly valve at the water outlet are controlled.
When the system sends a starting command to the water pump, the water pump is automatically started, and after the water pump runs for 10 seconds (which can be set through the touch screen and the intelligent platform terminal), the corresponding water outlet butterfly valve is automatically opened.
When the system sends a stop command to the water pump, the system automatically closes the butterfly valve of the water outlet corresponding to the water pump; when the system detects that the butterfly valve is closed in place, the water pump automatically stops.
4) The system is designed with perfect protection functions, such as water pump water leakage detection, overflow detection, upper and lower water level limit detection, butterfly valve over-moment detection, gate hoist fault detection and the like, and ensures that when the system is abnormal, the intelligent platform terminal issues fault information in time to remind relevant personnel of troubleshooting.
