Specifically, a flow data driving model is established by adopting a least square method, and then a flow alarm threshold value is deduced by the data driving model to carry out leakage alarm early warning.
More specifically, as shown in fig. 2, the flow of determining the data-driven control model of the flow parameter includes the following steps:
firstly, a conveying pump outlet flow measured value S401A of a flowmeter arranged at an outlet of an ore pulp conveying pump, a conveying pipeline middle flow measured value A401B of a flowmeter arranged in the middle of a conveying pipeline and a tailing dam inlet pipeline flow measured value A401C of a flowmeter arranged in an inlet pipeline of a tailing dam recovery pond are obtained.
Then, the measured value is uploaded to the controller, and whether the difference delta F1 between the measured value S401A of the outlet flow rate of the conveying pump and the measured value A401B of the intermediate flow rate of the conveying pipeline is within an allowable range or not is judged; judging whether the difference delta F2 between the measured intermediate flow value A401B of the conveying pipeline and the measured inlet pipeline flow value A401C of the tailing dam is within an allowable range or not; judging whether the difference delta F3 between the measured flow value A401C of the inlet pipeline of the tailing dam and the measured flow value S401A of the outlet of the conveying pump is within an allowable range or not; when the difference between each group of data is larger than the normal loss flow, the detection system jumps to the alarm control module S404, and when each group of flow parameters is normal, the detection system stores the above values, retains and records each measured flow value, provides correction data for the calculation of the difference range in the subsequent controller, and may set a periodic deletion function for the storage time.
And finally, establishing a flow data driving model.
In an embodiment of the invention, the alarm control module includes a single parameter alarm and a dual parameter alarm; the single parameter alarm is an alarm that any one of the flow data or the pressure data is abnormal; the double parameter alarm is an alarm that both the flow data and the pressure data are abnormal.
Specifically, in the actual operation process, in order to avoid the situation of missing report or false report of the monitoring system, two alarm modes are set in the alarm control module, which are an alarm for flow data and an alarm for pressure data.
More specifically, in order to prevent false leakage, the detection system designed by the invention simultaneously monitors the pipeline pressure and establishes a pressure mechanism model of the outlet of the ore pulp conveying pump. As shown in fig. 3, the process of determining the data-driven control model of the pressure parameter includes the following steps:
firstly, setting fixed value parameters for the delivery pump and establishing an outlet pressure mechanism model.
And then, obtaining a pressure alarm threshold P1 of the outlet of the conveying pump, a pressure alarm threshold P2 of the middle part and a pressure alarm threshold P3 of the inlet pipeline of the tailing dam.
Finally, in the controller, the pressure alarm threshold value P1 of the outlet of the conveying pump, the pressure alarm threshold value P2 of the middle position, the pressure alarm threshold value P3 of the inlet pipeline of the tailing dam and the measured value at the corresponding position are compared, the next operation is carried out on the measured value meeting the requirement, the measured value S401a of the outlet of the conveying pump, the measured value S401b of the middle position of the conveying pipeline and the measured value S401c of the inlet pipeline of the tailing dam are respectively obtained, the measured value meeting the requirement is circulated to the controller for normal return and storage, the next sampling value is worn on the top, the pressure value of the middle preset position and the pressure alarm threshold value of the inlet pipeline of the tailing dam are deduced according to the pressure alarm threshold value of the outlet of the ore pulp conveying pump, the length of the conveying pipeline and the flow rate of the ore pulp, and the comparison and judgment are carried out with the measured value. The measured value not meeting the requirement triggers the alarm control module, and the step goes to S404.
In an embodiment of the invention, the single parameter alert comprises a picture parameter pop-up flash on the image display; the two-parameter alarm comprises a picture parameter pop-up flash and a sound-light alarm. The alarm mode is more effective through the ascending of the alarm stage number.
Specifically, in an alarm control module of the detection system, when only flow data alarms, pressure data is normal or the flow of ore pulp is normal, or when only pressure data alarms, the module control block only gives an alarm and has no action, and a picture parameter of an LED touch screen of the image display pops up to flicker to remind an index worker. When the flow data and the pressure data exceed the threshold value and alarm, the detection system sends out an audible and visual alarm to remind index workers of confirming alarm prompt, then the ore pulp delivery pump is closed, and the ore pulp delivery is stopped. And then, the leakage position of the conveying pipeline is determined according to the information on the image display, and the maintainers can timely overhaul the conveying pipeline, so that the influence on the overall operation of the mine caused by the leakage of the conveying pipeline is reduced.
