Description

Technical Field

[0001] The invention relates to the technical field of data analysis, in particular to a multi-parameter data acquisition and analysis system for a mining submersible pump. Background Art

[0002] Submersible pumps have a wide range of uses. They can be applied to domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, fountain landscapes, water plants, hot water submersible pumps are used for hot spring bathing, and can also be used to extract groundwater from deep wells. They can also be used in water-lifting projects such as rivers, reservoirs, and canals.

[0003] Since the submersible pump needs to pump water continuously, the impeller needs to rotate continuously, which will generate heat; when the submersible pump is overloaded or runs for too long, the submersible pump is very easy to be damaged; and the submersible pump is located underwater, and the existing data acquisition system cannot monitor the water environment information and operating parameter information of the submersible pump in real time and perform detection and analysis, making it difficult to determine the loss status of the submersible pump, which will cause great safety hazards; for this reason, the present invention proposes a multi-parameter data acquisition and analysis system for mining submersible pumps. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a multi-parameter data acquisition and analysis system for a mining submersible pump.

[0005] To achieve the above-mentioned object, a first aspect of the present invention provides a multi-parameter data acquisition and analysis system for a mining submersible pump, comprising a data acquisition module, a data sorting module, a control center, a database and a loss analysis module;

[0006] The data acquisition module is a monitoring sensor group connected to the submersible pump, which is used to collect various parameter data during the operation of the submersible pump and mark the collected various parameter data as submersible pump operation data;

[0007] The submersible pump operation data includes submersible pump water environment information and submersible pump operation parameter information; the submersible pump water environment information refers to the water quality parameter information around the submersible pump; the submersible pump operation parameter information includes the vibration frequency of the submersible pump, energy consumption per unit time, internal and external temperature difference and pressure of the water pump inlet;

[0008] The data acquisition module is used to transmit the collected submersible pump operation data to the data sorting module for preprocessing; the data sorting module is used to report the preprocessed submersible pump operation data to the control center through the HART communication module for management personnel to study and analyze;

[0009] In one operation cycle, the loss analysis module is used to obtain the submersible pump operation data to perform operation loss index ZH analysis. The specific analysis steps are as follows:

[0010] Obtain the submersible pump operation data and calculate the submersible pump operation time as TL; evaluate the water quality pollution coefficient Sw according to the submersible pump water environment information, and mark the maximum water quality pollution coefficient as St;

[0011] Evaluate the pumping coefficient YX of the submersible pump based on the submersible pump operating parameter information;

[0012] Using the formula The operating loss index ZH of the submersible pump is calculated, where b5 and b6 are preset coefficient factors; f is the preset balance coefficient;

[0013] If the operation loss index ZH ≥ the preset loss threshold, the submersible pump is judged to be seriously damaged and a loss abnormality signal is generated to the control center; after receiving the loss abnormality signal, the control center controls the submersible pump to shut down and controls the alarm module to sound an alarm to prompt the management personnel to inspect the submersible pump.

[0014] Furthermore, the specific evaluation steps of the pumping coefficient YX are:

[0015] The maximum vibration frequency of the submersible pump is marked as Zmax, the maximum energy consumption per unit time is marked as Emax, the maximum temperature difference between inside and outside is marked as Wmax, and the maximum water inlet pressure is marked as Ymax;

[0016] Using the formula YX = (Zmax × b1 + Emax × b2) (Wmax×b3+Ymax×b4) The pumping coefficient YX of the submersible pump is calculated, where b1, b2, b3, and b4 are all preset coefficient factors.

[0017] Furthermore, the specific evaluation steps of the water pollution coefficient Sw are:

[0018] Compare each water quality parameter with the safety data of the corresponding water quality parameter stored in the database to obtain the data difference of the corresponding water quality parameter;

[0019] The data difference of each water quality parameter greater than zero is obtained, and the water quality pollution coefficient Sw is calculated by combining the impact factors of each water quality parameter on the water environment stored in the database.

[0020] Furthermore, the water quality parameter information includes dissolved oxygen information, turbidity information, sulfide information, pH value information and water temperature information.

[0021] Furthermore, the data acquisition module is a monitoring sensor group connected to the submersible pump; the monitoring sensor group includes a water quality detector, a temperature sensor, a pressure sensor, a vibration sensor and an electric energy metering sensor.

[0022] Furthermore, preprocessing refers to: traversing the submersible pump operation data, screening and locating, performing mean compensation on abnormal data and missing data, and cleaning up redundant and invalid data.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 , the first aspect of the present invention provides a multi-parameter data acquisition and analysis system for a mining submersible pump, including a data acquisition module, a data sorting module, a HART communication module, a control center, a database, a loss analysis module and an alarm module;

[0030] The data acquisition module is a monitoring sensor group connected to the mining submersible pump, which is used to collect various parameter data of the mining submersible pump during operation, and mark the collected parameter data as submersible pump operation data;

[0031] Submersible pump operation data includes submersible pump water environment information and submersible pump operation parameter information; submersible pump water environment information refers to water quality parameter information around the submersible pump; submersible pump operation parameter information includes vibration frequency, energy consumption per unit time, internal and external temperature difference and pressure at the water pump inlet;

[0032] In this embodiment, the monitoring sensor group includes a water quality detector, a temperature sensor, a pressure sensor, a vibration sensor, and an electric energy metering sensor;

[0033] The water quality detector is used to detect the water quality parameter information around the submersible pump in real time. The water quality parameter information includes dissolved oxygen information, turbidity information, sulfide information, pH value information and water temperature information;

[0034] The temperature sensor is arranged on the inner wall and outer wall of the pump casing of the submersible pump, and is used to collect the temperature of the inner wall and outer wall of the pump casing in real time to obtain the temperature difference between the inside and the outside;

[0035] Generally speaking, when a submersible pump is operating, the impeller needs to rotate continuously, which will generate heat. Therefore, the temperature of the inner wall of the pump casing is higher than the temperature of the outer wall of the pump casing. The temperature difference between the inside and outside = the temperature of the inner wall of the pump casing - the temperature of the outer wall of the pump casing.

[0036] The pressure sensor is arranged at the water inlet of the submersible pump, and is used to collect the pressure data of the water inlet of the submersible pump in real time; the vibration sensor is arranged on the motor housing of the submersible pump, and is used to collect the vibration frequency of the submersible pump motor in real time; the electric energy metering sensor is arranged on the circuit of the submersible pump motor stator, and is used to collect the energy consumption per unit time of the submersible pump in real time;

[0037] The data acquisition module is used to transmit the collected submersible pump operation data to the data sorting module for preprocessing; preprocessing refers to: traversing the submersible pump operation data, screening and locating, performing mean compensation for abnormal data and missing data, and cleaning up redundant and invalid data;

[0038] The data sorting module is used to report the pre-processed submersible pump operation data to the control center through the HART communication module for management personnel to study and analyze, provide guidance for the refined management of submersible pumps and user services, and improve the management efficiency of submersible pumps;

[0039] In this embodiment, within an operation cycle, the loss analysis module is used to obtain the submersible pump operation data to perform operation loss index ZH analysis. The specific analysis steps are:

[0040] In one operation cycle, the operation data of the submersible pump is obtained and the operation time period of the submersible pump is obtained through analysis;

[0041] It should be noted that an operation cycle refers to a cycle from the start of operation to the end of operation of the submersible pump. The operation time period of the submersible pump obtained by analysis at this time is the operation time period of this operation cycle;

[0042] Obtain the water environment information of the submersible pump and calculate the water pollution coefficient Sw; specifically:

[0043] Compare each water quality parameter with the safety data of the corresponding water quality parameter stored in the database to obtain a data difference of the corresponding water quality parameter; in this embodiment, the data difference includes a dissolved oxygen difference, a turbidity difference, a sulfide difference, a pH value difference and a water temperature difference; if the data difference of the corresponding water quality parameter is less than or equal to zero, it indicates that the corresponding water quality parameter does not cause water pollution;

[0044] Obtain the data difference of each water quality parameter that is greater than zero, and calculate the water quality pollution coefficient Sw by combining the impact factors of each water quality parameter on the water environment stored in the database;

[0045] Since the submersible pump is located underwater, if the water environment around the submersible pump is heavily polluted, it will also cause corrosion to the submersible pump; the water pollution coefficient Sw is used to reflect the wear of the water environment on the submersible pump; the larger the water pollution coefficient Sw, the more wear the water environment causes to the submersible pump;

[0046] During the operation period, the maximum vibration frequency of the submersible pump is marked as Zmax, the maximum energy consumption per unit time is marked as Emax, the maximum temperature difference between inside and outside is marked as Wmax, and the maximum water inlet pressure is marked as Ymax;

[0047] Using the formula YX = (Zmax × b1 + Emax × b2) (Wmax×b3+Ymax×b4) The pumping coefficient YX of the submersible pump is calculated, where b1, b2, b3, and b4 are all preset coefficient factors;

[0048] In this embodiment, since the submersible pump needs to pump water continuously, the pumping coefficient YX is used to reflect the pumping load of the submersible pump. The larger the pumping coefficient YX is, the heavier the load is when the submersible pump is running, and the more wear and tear is caused to the submersible pump.

[0049] The operation time of the submersible pump is TL, and the maximum value of the water pollution coefficient is marked as St; using the formula The operating loss index ZH of the submersible pump is calculated, where b5 and b6 are preset coefficient factors; f is the preset balance coefficient;

[0050] Compare the operation loss index ZH with the preset loss threshold. If the operation loss index ZH ≥ the preset loss threshold, it is determined that the submersible pump is seriously damaged and an abnormal loss signal is generated.

[0051] The loss analysis module is used to transmit the abnormal loss signal to the control center. After receiving the abnormal loss signal, the control center controls the submersible pump to stop and controls the alarm module to sound an alarm to prompt the management personnel to inspect the submersible pump and improve the safety of the submersible pump operation.

[0052] The present application can collect and preprocess multiple types of data (such as submersible pump water environment information and submersible pump operating parameter information) through the data acquisition module, and complete loss analysis based on the preprocessed data, so as to timely inspect and repair the submersible pump and eliminate hidden dangers of the submersible pump, thereby improving the management efficiency of the submersible pump.

[0053] Part of the data in the above formula is calculated by removing the dimension and taking its numerical value. The formula is a formula closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.
