Description

Automatic operation method, system, medium and equipment of lift pump based on queue management Technical Field The invention belongs to the technical field of metallurgy, and particularly relates to an automatic operation method, an automatic operation system, an automatic operation medium and automatic operation equipment for a lifting pump based on queue management. Background The continuous casting square billet cyclone pool is mainly used for collecting open-circuit water, secondary cooling water, slag flushing water and the like generated in the cooling process of continuous casting equipment. After the primary sedimentation treatment, the water is lifted to a advection pool or a water treatment plant for further treatment by a cyclone lifting pump. Current automatic start and stop strategies for the lift pump are performed based on a fixed threshold of water level. For example, when the water level exceeds a certain set point, the corresponding pump is started, and when the water level is below another set point, the pump is stopped. This strategy, while straightforward, has problems such as uneven use of the device and large water level fluctuations. 1# PumpWater level >3.0mWater level <2.5m2# PumpWater level >3.2mWater level <3.0m3# PumpWater level >3.5mWater level <3.2m4# PumpWater level >4.75mWater level <3.5m Table 1 current lift pump operating strategy As shown in Table 1, the continuous casting billet cyclone pool is used for water treatment plants by a lifting pump, the pool depth of the cyclone pool is 8.0m, the process requirement water level is in the range of [2.5m,4.9m ], and the long-term use stability is in the range of [2.9m,3.6m ]. Based on this, there are problems as follows: The device is used unevenly, the No. 1 pump runs for a long time, the No.2 pump runs frequently, the No. 3 pump runs rarely, and the No. 4 pump runs basically. In actual operation, the failure rate of the No. 1 pump and the No.2 pump is high, and the No. 4 pump is difficult to detect when the No. 4 pump fails. Because of the different activation thresholds of the different pumps, some pumps (e.g., 1# pump, 2# pump) run too long, while other pumps (e.g., 3# pump, 4# pump) run too short. Such uneven use can lead to increased wear and failure rates of the equipment. The water level fluctuation is large, if the No. 1 pump fails, the No. 2 pump is started to pump water when the water level rises to 3.2m, and in this way, the No. 3 pump is started when the water level rises to 3.5m when the No. 2 pump fails. In particular, when the 3# pump fails, the 4# pump is started only when the water level rises to 4.75 m. Thus, in the event of pump failure, the water level will fluctuate significantly in a short period of time, even beyond the process-required water level range, as the water level needs to rise to a higher threshold value to start the next pump. Therefore, how to provide a reasonable pump operation strategy to solve the above-mentioned problems is a technical need in the art. Disclosure of Invention In view of the above-mentioned drawbacks of the prior art, the present invention aims to provide an automatic operation of a lift pump based on queue management, which solves the problems of uneven equipment consumption and large water level fluctuation caused by a failure of a certain lift pump motor due to too simple starting and stopping strategy of a plurality of lift pumps in production operation. In a first aspect, the invention provides an automatic operation method of a lift pump based on queue management, which comprises the following steps of acquiring state information of each lift pump in real time; Establishing a ready queue and an operation queue of the lift pump based on the lift pump state information, and calculating the current operation quantity of the lift pump; acquiring current water level information, and acquiring the start-stop demand quantity of the lifting pump based on the current water level information; And adjusting the operation strategy of the lifting pump based on the comparison result of the lifting pump start-stop demand quantity and the current lifting pump operation quantity and the queue information. In one implementation of the first aspect, the lift pump status information includes a lift pump operating status and a frequency converter operation setting parameter. In an implementation manner of the first aspect, the step of establishing a ready queue and an operation queue of the lift pump based on the lift pump status information includes the following steps: Adding a lift pump in a stopped state and without faults to the ready queue, adding a lift pump in running to the running queue, and recording an updated state in real time; recording a start and stop sequence of the lift pump based on the updated status; and establishing a start-stop queue based on the start-stop sequence of the lift pump.
