[0036] Figure 2 Schematic diagram of the structure of a pump unit operation fault judgment and response system according to an embodiment of the present invention. DETAILED DESCRIPTION

[0037] like Figure 1 As shown, a method for judging and responding to pump unit operation faults according to an embodiment of the present invention includes the following steps:

[0038] S1. Obtain the current detection value of the target parameter corresponding to each to-be-tested area of ​​the target pump unit.

[0039] Among them, ① the target pump unit is: an oil pipeline pump unit, which can also be other types of pump units, without any restrictions. ② the area to be tested is: any area of ​​the target pump unit, which can be the drive end or the non-drive end, without any restrictions. ③ the target parameters include but are not limited to: the temperature value, pressure value, and vibration value of the drive end or non-drive end of the target pump unit. ③ the current detection value is: the effective value of the target parameter obtained through testing, which is used to determine whether the target parameter corresponding to a certain test area has a fault.

[0040] It should be noted that ① there is no limit to the method for obtaining the current detection value. For example, when the target parameter is a temperature value, the temperature value of the target pump unit can be collected through a temperature sensor. ② The target pump unit can have multiple test areas for fault diagnosis for the same target parameter. For example, test area A of the target pump unit corresponds to the temperature value of the drive end, and test area B of the target pump unit corresponds to the temperature value of the non-drive end. In other words, the target pump unit can have multiple fault detection temperature values.

[0041] S2. When the target pump unit is in operation or to be started, determine whether the current detection value of the target parameter corresponding to any area to be tested is within any preset fault level range of the target parameter corresponding to any area to be tested. If so, perform a fault response according to the fault level corresponding to the preset fault level range, until the current detection value of the target parameter corresponding to each area to be tested is judged to determine whether to perform a fault response.

[0042] ① In this embodiment, an enable shielding condition is provided, meaning that the target pump unit only performs fault determination and fault response under certain conditions. For example, the subsequent fault determination and fault response steps are only performed when the target pump unit is in operation or in the waiting-to-start state. ② The preset fault level range includes: a first preset fault level range and a second preset fault level range; the fault levels include: a first fault level (general fault) and a second fault level (major fault). The first preset fault level range corresponds to the numerical range of general faults for the target parameter, and the second preset fault level range corresponds to the numerical range of major faults for the target parameter. For example, when the target parameter corresponding to a certain area is temperature, the first preset fault level range for the temperature value can be set to: 70°C-80°C, and the second preset fault level range for the temperature value can be set to above 80°C. In this case, if the temperature value is 75°C, the target pump unit is determined to have a general fault in the temperature value of the certain area; if the temperature value is 90°C, the target pump unit is determined to have a major fault in the temperature value of the certain area. ③ Fault response methods include, but are not limited to: issuing an alarm signal, controlling the target pump unit to stop operation, and recording the fault.

[0043] It should be noted that in step S2, it is possible to simultaneously judge and respond to whether there is a fault in the target parameters of multiple test areas of the target pump unit (multi-threaded processing), or it is possible to judge and respond to whether there is a fault in the target parameters corresponding to multiple test areas of the target pump unit in turn (single-threaded processing), and there is no restriction here.

[0044] Preferably, step S1 includes:

[0045] S11 . Constructing a plurality of first detection points for measuring target parameters corresponding to each to-be-tested area of ​​the target pump unit.

[0046] The first detection point is located on the target pump unit and is used to detect the current value of the target parameter corresponding to a certain test area. One detection point corresponds to one value. In this embodiment, the number of first detection points for the target parameter corresponding to each test area is greater than or equal to three.

[0047] S12. Determine a current detection value of the target parameter corresponding to each area to be measured according to the first detection value collected at each first detection point of the target parameter corresponding to each area to be measured.

[0048] Specifically, step S12 includes:

[0049] S121 , determining a current detection value of the target parameter corresponding to any area to be measured based on the first detection value collected at each first detection point of the target parameter corresponding to any area to be measured.

[0050] Specifically, step S121 includes:

[0051] S1211: Calculating the difference between every two first detection values ​​of the target parameter corresponding to any one of the test areas to obtain a plurality of detection differences, and determining whether each detection difference is within a preset difference range, thereby obtaining a determination result for each detection difference.

[0052] Among them, ① multiple detection differences are: the difference between every two first detection values. For example, assuming that there are three first detection values ​​of the temperature value: A1, A2, and A3, the multiple detection differences corresponding to the temperature value are: A1-A2 (or A2-A1), A2-A3 (or A3-A2), A1-A3 (or A3-A1). ② The preset difference range is set according to the actual operating conditions of the oil pipeline where the target pump unit is located and the operating performance parameters of the equipment. This value needs to fit the actual production operation and be accurate to the precise threshold of each detection point. For example, the preset difference range is set to: (-a, a), where a is any non-zero value.

[0053] S1212A: When the judgment results of all detection differences are yes, based on the preset screening method, N1 first detection values ​​are selected from all first detection values ​​of the target parameter corresponding to any of the tested areas, and the average value of the N1 first detection values ​​is determined as the current detection value of the target parameter corresponding to any of the tested areas.

[0054] Wherein, ① N1 ≥ 2 and N1 ≤ M1, N1 is a positive integer, and M1 is the number of all current detection values ​​of the target parameter corresponding to any area to be tested. ② The preset screening method is: high selection or low selection.

[0055] S122. Repeat step S121 until the current detection value of the target parameter corresponding to each area to be tested is obtained.

[0056] It should be noted that the current detection value of the target parameter corresponding to each to-be-tested area of ​​the target pump unit is obtained in the same manner.

[0057] Preferably, step S121 further includes:

[0058] S1212B: When the judgment result of any detection difference of the target parameter corresponding to any of the tested areas is negative, the first detection value that causes the largest detection difference will be deleted from all the first detection values ​​of the target parameter corresponding to any of the tested areas, and N2 current detection values ​​will be selected from the remaining first detection values, and the average value of the N2 first detection values ​​will be determined as the current detection value of the target parameter corresponding to any of the tested areas.

[0059] Among them, N2≥2 and N2≤M2, M2=M1-1, and N2 is a positive integer.

[0060] Preferably, any one of the preset fault ranges is: a first preset fault range or a second preset fault range; the fault levels include: a first fault level and a second fault level; and the step of performing a fault response according to the fault level corresponding to the preset fault level range of the target parameter corresponding to any one of the preset ranges includes:

[0061] When the preset fault level range of the target parameter corresponding to any of the preset ranges is within the first preset fault range, the fault level of the target parameter corresponding to the preset range is determined to be the first fault level, and a first alarm signal is issued. Alternatively, when the preset fault level range of the target parameter corresponding to any of the preset ranges is within the second preset fault range, the fault level of the target parameter corresponding to the preset range is determined to be the second fault level, a second alarm signal is issued, and the target pump unit is controlled to stop operating.

[0062] Among them, ① the first alarm signal is: an alarm signal of the first fault level (general fault). ② the second alarm signal is: an alarm signal of the second fault level (major fault).

[0063] Preferably, the step of performing a fault response according to a fault level corresponding to a preset fault level range of a target parameter corresponding to any preset range further includes:

[0064] The first alarm signal or the second alarm signal corresponding to the target parameter corresponding to any preset range is sent to the monitoring platform and multiple terminal devices.

[0065] Among them, ① the monitoring platform is used to record and store the fault information and alarm signals of the target pump unit, and can send a reset signal to control the alarm. ② The terminal device is: the terminal devices of multiple production and operation personnel related to the target pump unit.

[0066] Preferably, it also includes:

[0067] Within a preset time period, when the number of times the first alarm signal of the target parameter corresponding to any preset range is issued exceeds the preset number and the second alarm signal of the target parameter corresponding to any preset range is not issued, the first alarm signal of the target parameter corresponding to any preset range will be latched until a reset signal of the target parameter corresponding to any preset range is received, and the alarm will be stopped.

[0068] Among them, ① the preset time period is set according to demand and there is no limit here. For example: 180S, which can be recorded by a timer. ② The preset number of times is set according to demand and there is no limit here. For example: 5 times, which can be recorded by a counter. ③ When the first alarm signal of the target parameter corresponding to any preset range is not latched, when the current detection value obtained at the next moment does not meet any preset fault level range, the first alarm signal of the target parameter corresponding to any preset range will be interrupted and the alarm will stop automatically. When the first alarm signal of the target parameter corresponding to any preset range is latched, the first alarm signal of the target parameter corresponding to the preset range will not be automatically disconnected, and the alarm will stop only after receiving the reset signal from the monitoring platform.

[0069] Preferably, each second alarm signal corresponds to a flag value, and the method further includes:

[0070] A memory tag group is constructed, and based on the time sequence, the flag value of each second alarm signal is stored in the memory tag group in sequence, and the memory tag group is output based on the graphic form until the tag reset signal is received, and the memory tag group is reset.

[0071] Among them, the memory tag group is: a group of memory tags.

[0072] Specifically, ① first set the first tag in the memory tag group as the trigger memory valid tag. After the trigger memory valid tag is assigned the flag value of the fault, the next tag is set as the trigger memory valid tag in sequence according to the preset tag order in the memory tag group. That is, based on the time sequence of fault detection, the second alarm signal of each second fault category is recorded. ② At the same time, the entire memory tag group is graphically displayed, showing the alarm sequence of the entire process, the first fault alarm trigger, and the current fault alarm trigger. ③ When there is a reset signal, the data of the entire memory tag group is reset to zero.

[0073] The technical solution of this embodiment ensures the stable operation of the pump unit and reduces potential hazards during operation by determining the corresponding fault level based on the pump unit's fault information and issuing a corresponding alarm response. This can be particularly helpful for oil pipeline pump units, reducing accidents during operation and better meeting the requirements for safe and stable oil pipeline transportation.

[0074] like Figure 2 As shown, a pump unit operation fault judgment and response system 200 according to an embodiment of the present invention includes: an acquisition module 210 and an operation module 220;

[0075] The acquisition module 210 is used to: acquire the current detection value of the target parameter corresponding to each test area of ​​the target pump unit;

[0076] The operation module 220 is used to: when the target pump unit is in the operating state or the waiting-to-start state, determine whether the current detection value of the target parameter corresponding to any test area is within any preset fault level range of the target parameter corresponding to any test area; if so, perform a fault response according to the fault level corresponding to the preset fault level range, until the current detection value of the target parameter corresponding to each test area is judged to determine whether a fault response is performed.

[0077] The technical solution of this embodiment ensures the stable operation of the pump unit and reduces potential hazards during operation by determining the corresponding fault level based on the pump unit's fault information and issuing a corresponding alarm response. This can be particularly helpful for oil pipeline pump units, reducing accidents during operation and better meeting the requirements for safe and stable oil pipeline transportation.
