In the application, a plurality of monitoring points can be arranged to monitor different positions in the hydraulic operation system, for example, the plurality of monitoring points are sequentially arranged according to the upstream and downstream sequences of the system, and the pressure of the plurality of monitoring points is monitored to obtain the pressure distribution data of each monitoring point. The pressure distribution data can be continuous pressure distribution data of the same monitoring point in different periods, or pressure distribution data of different monitoring points at the same time.

And when the second data does not meet the preset rule, determining that the system is abnormal.
And when the hydraulic operation system is abnormal, sending out an alarm prompt.
The application has the beneficial effects that: acquiring first data of each monitoring point of a hydraulic operation system, wherein the first data comprise pressure distribution data of each monitoring point and/or volumetric efficiency of the hydraulic operation system; and generating second data from the first data, wherein the second data comprises at least one of: the method comprises the steps of comparing pressure values of all monitoring points with a first comparison result of a standard curve, a second comparison result of pressure curves of the same monitoring point and different periods, a third comparison result of volumetric efficiency of different periods and a fourth comparison result of pressure values of different monitoring points at the same moment, so that when the system is not abnormal, comparison between the values of the monitoring points and corresponding standard values, comparison between different periods of the same monitoring point and comparison between different monitoring points are realized, whether the hydraulic operation system is abnormal or not is judged according to the second data, and an alarm prompt is sent when the hydraulic operation system is abnormal. And then alarm is given when the system is abnormal, so that an operator is prompted to maintain, and the equipment fault risk is reduced.
In one embodiment, the first data is the pressure value of the monitoring point, and the step S102 may be implemented as the following step A1:
in the step A1, when the hydraulic operating system operates, comparing the pressure value of each monitoring point with the pressure value of the standard curve corresponding to each monitoring point at the same time point to generate a first comparison result of the pressure value of each monitoring point and the standard curve, and taking the first comparison result as second data;
the above step S103 may be implemented as the following step A2:
in step A2, when the difference value between the pressure value of each monitoring point represented by the first comparison result and the pressure value of the standard curve corresponding to each monitoring point at the same time point is greater than a first preset value, it is determined that the abnormality exists in the hydraulic operating system.
In this embodiment, in order to determine whether an abnormality occurs in the system by comparing the pressure values of the monitoring points of the current system with the standard pressure values of the system in the normal operation state. Therefore, the system records the pressure change characteristics under different hydraulic oil pressures and flows in advance in the running process, generates a complete standard curve of each monitoring point in the running period of the system, and stores the standard curve corresponding to each monitoring point.
When the hydraulic operating system operates, the pressure value of each monitoring point is compared with the pressure value of the standard curve corresponding to each monitoring point at the same time point, so that a first comparison result of the pressure value of each monitoring point and the standard curve is generated, and the first comparison result is used as second data. Specifically, taking a certain monitoring point as an example, firstly, acquiring an operation time point t of a current system in a complete operation period and a pressure value P x of the monitoring point, acquiring a pressure value P xs of the same time point from a standard curve according to the operation time point t, comparing the current pressure value P x of the monitoring point with a pressure value P xs of the same time point acquired from the standard curve, and taking the obtained first comparison result as second data. It should be noted that the comparison process may take various forms, for example, a difference between the current pressure value and the pressure value obtained from the standard curve at the same time point may be directly obtained as the second data; or acquiring whether the difference between the current pressure value and the pressure value acquired from the standard curve at the same time point exceeds a preset interval, and taking the difference as second data, wherein the difference exceeds the preset interval or does not exceed the preset interval. The application is not limited to specific alignment formats.
And when the difference value of the pressure value of each monitoring point represented by the first comparison result and the pressure value of the standard curve corresponding to each monitoring point at the same time point is larger than a first preset value, determining that the hydraulic operation system is abnormal. For example, if the second data is greater than the first preset value or exceeds the preset interval, the difference value of the pressure value of each monitoring point and the pressure value of the standard curve corresponding to each monitoring point at the same time point is greater than the first preset value, and at the moment, it is determined that the hydraulic operation system is abnormal.
The beneficial effects of this embodiment lie in: the pressure value obtained by each monitoring point of the system is compared with the corresponding pressure value in the standard curve in the running process of the system to determine whether the pressure value of each monitoring point is in a normal interval, and when the pressure value of each monitoring point deviates from the pressure value of the standard curve, the pressure abnormality monitored by the point is indicated, and the system is abnormal.
In one embodiment, the first data is the pressure value of the monitoring point, and the step S102 may be implemented as the following step a11:
In step a11, when the hydraulic operating system is running, comparing the pressure value of each monitoring point with the pressure value of the standard curve corresponding to each monitoring point at the same time point to generate a first comparison result of the pressure curve of each monitoring point and the standard curve, and taking the first comparison result as second data;
the above step S103 may be implemented as the following step a12:
In step a12, when the difference value between the pressure curve of the first comparison characterization monitoring point and the standard curve is greater than a fifth preset value, determining that the second data judges that the hydraulic operating system is abnormal.
In this embodiment, in order to reduce a situation of false alarm caused by an error in the obtained pressure value at a certain time point, when the hydraulic operating system is running, the pressure value of each monitoring point is compared with the pressure value of the standard curve corresponding to each monitoring point at the same time point, so as to generate a first comparison result of the pressure curve of each monitoring point and the standard curve, and the first comparison result is used as second data. Specifically, taking a certain monitoring point as an example, the pressure values monitored by a plurality of preset time points in the current period and the pressure values monitored by the standard curve at a plurality of preset time points are subjected to difference, and the difference values of the plurality of preset time points are summed to obtain second data. For another example, the similarity between the pressure curve and the standard curve of each monitoring point in the current period can be calculated, and the calculated similarity is used as the second data. And then, when the difference value of the pressure curve of the first comparison characterization monitoring point and the standard curve is larger than a fifth preset value, determining that the second data judges that the hydraulic operating system is abnormal.
The beneficial effects of this embodiment lie in: by comparing the pressure curve in the current period of each monitoring point with the standard curve, false alarm caused by inaccurate monitoring data at a certain point is avoided.
In one embodiment, the first data is a pressure curve of the monitoring point, and the step S102 may be implemented as the following step B1:
comparing the pressure curves of the same monitoring point and different periods to generate second comparison results of the pressure curves of the same monitoring point and different periods, and taking the second comparison results of the pressure curves of the same monitoring point and different periods as second data, wherein the second comparison results are comparison results of the pressure curves of the same monitoring point and adjacent periods and/or comparison results of the pressure curves of the same monitoring point and the current period and the initial period.
In this embodiment, by comparing the pressure curves of multiple periods of the same monitoring point, the pressure curves of different periods of the same monitoring point are compared to generate a second comparison result of the pressure curves of different periods of the same monitoring point, and the second comparison result of the pressure curves of different periods of the same monitoring point is used as second data to determine whether the system is abnormal or not according to the second data.
Specifically, firstly, when the system operates, the obtained pressure values of all monitoring points are generated into corresponding pressure curves, wherein the real-time pressure obtained by all the monitoring points can be directly generated into a pressure curve C; in one embodiment, in order to reduce the influence of the fluctuation of different periods, the pressure data acquired in the preset number n of periods before the current period is counted, for example, the pressure values of the periods at the same time point are averaged, the pressure values of the current period at the time point are used as the pressure values, and the pressure curve C is generated by the counted pressure values.
And then, after the pressure curves are obtained, comparing the pressure curves of the same monitoring point and different periods to generate a second comparison result of the pressure curves of the same monitoring point and different periods, wherein the second comparison result can be the comparison result of the pressure curves of the adjacent periods of the same monitoring point or the comparison result of the pressure curves of the current period and the initial period of the same monitoring point. The specific comparison process is implemented in various ways, for example, taking a certain monitoring point as an example, taking differences between pressure values monitored at a plurality of preset time points in a current period and pressure values monitored at a plurality of preset time points of a pressure curve of an adjacent period or an initial period, and summing the differences at a plurality of preset time points to obtain a second comparison result, wherein the second comparison result is second data. For another example, the similarity between the pressure curve of each monitoring point in the current period and the pressure curve of the adjacent period or the initial period may be calculated, and the calculated similarity is used as the second data.
In one embodiment, the step S103 may be implemented as the following step B2:
In the step B2, when the comparison result of the pressure curves of the adjacent periods of the same monitoring point indicates that a numerical point with a difference value larger than a second preset value exists in the pressure curves of the adjacent periods, determining that the hydraulic operation system is abnormal;
Or alternatively
When the comparison result of the pressure curves of the current period and the initial period of the same monitoring point indicates that a numerical point with a difference value larger than a third preset value exists in the pressure curve of the current period and the pressure curve of the initial period, determining that the hydraulic operation system is abnormal;
In this embodiment, the comparison is performed between the pressure curve obtained in the current period and the previous period, and when the comparison result of the pressure curves of the adjacent periods of the same monitoring point indicates that there is a numerical point with a difference value greater than a second preset value in the pressure curves of the adjacent periods, for example, when the difference between the pressure peak value in the current period and the pressure peak value in the previous period is too large, it is indicated that there is a sudden change in the pressure of the current system, and it is determined that there is an abnormality in the hydraulic operating system.
The standard curve is established or calculated according to a statistical method after actual measurement. The calibration curve for the first time is permanently stored once generated, and is still taken out after a long time to be compared with the calibration curve for the stage, so that the creep condition of the calibration curve is determined, therefore, in the embodiment, whether the creep occurs in the system pressure curve or not can also be monitored by comparing the pressure curve obtained in the current period with the pressure curve in the initial period, and when the comparison result of the pressure curve in the current period and the pressure curve in the initial period at the same monitoring point indicates that the difference value between the pressure curve in the current period and the pressure curve in the initial period is larger than a numerical point of a third preset value, the abnormality of the hydraulic operating system is determined.
In one embodiment, the step S103 may be further implemented as the following step B3:
In the step B3, when the integral difference value of the adjacent periodic curves of the same monitoring point is larger than a sixth preset value, determining that the hydraulic operating system is abnormal;
Or alternatively
And when the difference value of the current period and the integral initial period curve of the same monitoring point is larger than a sixth preset value, determining that the hydraulic operating system is abnormal.
In the embodiment, whether the system is abnormal or not is determined by comparing the integral pressure curves of different periods of each monitoring point. For example, the differences of the overall pressure curves at preset time points are summed, or the similarity between the overall pressure curves is calculated. Comparing the pressure curve acquired in the current period with the previous period to monitor whether the system pressure is suddenly changed, and determining that the hydraulic operation system is abnormal when the integral difference value of the adjacent period curves of the same monitoring point is larger than a sixth preset value. Or comparing the pressure curve obtained in the current period with the pressure curve of the initial period to monitor whether the system pressure curve is creeping, for example, the time between the current period and the initial period needs to have a certain span (such as several months and half a year), and the period in the middle interval needs to have a certain number (such as more than ten thousands of periods). Therefore, when the difference value of the current period and the integral initial period curve of the same monitoring point is larger than a sixth preset value, the hydraulic operation system is determined to have abnormality.
In one embodiment, the first data is volumetric efficiency of different periods, and the step S102 may be implemented as the following step C1:
in the step C1, volumetric efficiency of different periods is compared to generate a third comparison result of the volumetric efficiency of different periods, and the third comparison result is used as second data;
the above step S103 may be implemented as the following step C2:
In step C2, when the difference value of the volumetric efficiency of the third comparison result representing different periods is greater than a fourth preset value, it is determined that an abnormality exists in the hydraulic operating system.
In the present embodiment, it is determined whether an abnormality occurs in the hydraulic operating system by monitoring the volumetric efficiency of the hydraulic operating system. Volumetric efficiency refers to the ratio of the output fluid of the hydraulic operating system to the capacity of the hydraulic pump during operation, and represents the ratio of the actual output fluid to the theoretical output fluid of the hydraulic operating system. Volumetric efficiency is calculated from pressure data monitored in real time. The volumetric efficiency is calculated in a cycle of strokes, and the controller calculates the volumetric efficiency once after each stroke is completed.
And comparing the volumetric efficiency of different periods to generate a third comparison result of the volumetric efficiency of different periods, and taking the third comparison result as second data. The volume efficiency of the hydraulic operating system can directly take the ratio of the monitored liquid flow in the current period to the capacity of the hydraulic pump as the volume efficiency in the current period; in addition, in order to reduce the influence of the data fluctuation, the monitored value of the volumetric efficiency of the preset number m of monitored periods before the current period may be taken as the volumetric efficiency of the current period. The specific comparison process is implemented in various ways, for example, under the condition that a certain output pressure is selected by the hydraulic operation system, the change value of the volumetric efficiency of the current period and the volumetric efficiency of the previous period or the initial period of the same monitoring point is used as second data. For another example, the number of strokes required for outputting the same amount of liquid in the current period may be determined according to the volumetric efficiency of the hydraulic operation system, and the difference between the required number of strokes may be used as the second data.
And when the difference value of the volumetric efficiency of the third comparison result representing different periods is larger than a fourth preset value, determining that the hydraulic operating system is abnormal. For example, an excessive decrease in capacity efficiency in the current cycle or a significant increase in the number of strokes required may indicate an abnormality in the hydraulic operating system.
The beneficial effects of this embodiment lie in: the capacity of the hydraulic operating system for outputting liquid is monitored through the volumetric efficiency of the hydraulic operating system, and when the difference of the liquid capacities of the same monitoring point output in different periods is larger than a fourth preset value, the capacity of the system for outputting liquid is changed, and the abnormal condition of the hydraulic operating system is indicated.
In one embodiment, the first data is the pressure value at the same time at different monitoring points, and the step S102 may be implemented as the following step D1:
In the step D1, comparing the pressure values of different monitoring points at the same time to generate a fourth comparison result of the pressure values of the different monitoring points at the same time, and taking the fourth comparison result as second data;
In case the hydraulic operating system is not equipped with a device capable of blocking the free diffusion of pressure and/or causing a variation in pressure upstream and downstream, the above-mentioned step S103 may be implemented as the following steps D2-D3:
In step D2, according to the fourth comparison result, whether the pressure value of the downstream monitoring point is greater than the pressure value of the upstream adjacent monitoring point at the same time is determined;
in step D3, when the pressure value of the downstream monitoring point is greater than the pressure value of the upstream adjacent monitoring point at the same time, it is determined that an abnormality exists in the hydraulic operating system.
In this embodiment, the pressure values obtained by multiple monitoring points in the system are compared to determine whether an abnormality occurs in the system.
Comparing the pressure values of different monitoring points at the same moment to generate a fourth comparison result of the pressure values of the different monitoring points at the same moment, and taking the fourth comparison result as second data. For example, for a liquid hydrogen system, assume that the liquid hydrogen pump outlet pressure is P1, the downstream nearest second point pressure (e.g., vaporizer pressure) is P2, the downstream third point pressure (e.g., buffer tank pressure) is P3, and so on until the last pressure Pn, the numerical sequence numbers are arranged in an upstream-downstream relationship. And comparing the pressure values of different monitoring points to obtain a fourth comparison result, namely sequencing the pressure values, and taking the fourth comparison result as second data.
And judging whether the condition that the pressure value of the downstream monitoring point is larger than the pressure value of the upstream adjacent monitoring point at the same moment exists or not according to the fourth comparison result. Under the normal operation condition of the system, when the hydraulic operation system is not provided with equipment (such as a one-way valve, a control valve, an ejector and the like) capable of blocking free pressure diffusion and/or causing upstream and downstream pressure change, the pressure values of the monitoring points are equal or gradually decreased according to the upstream and downstream sequence, namely, when the digital serial numbers are sequentially arranged according to the upstream and downstream relation, the following logic is satisfied: p1 is more than or equal to P2 is more than or equal to P3 is more than or equal to Pn. For example, if there is a vehicle that is being hydrogenated, then as the downstream hydrogen is being output, the downstream pressure decreases, and then the upstream pressure is greater than the downstream pressure; when no vehicle is hydrogenated, the outlet pressure of the hydraulic pump is equal to both the carburetor pressure and the rear surge tank pressure. Thus, when there is a situation in which the pressure value of the downstream monitoring point is greater than the pressure value of the upstream adjacent monitoring point at the same time, it is determined that an abnormality exists in the hydraulic operation system.
In addition, under the condition that the hydraulic operation system is provided with equipment capable of blocking free pressure diffusion and/or causing pressure upstream and downstream changes, comparing according to specific characteristics of pressure changes of a process system caused by the equipment, generating second data according to comparison results, and judging whether the hydraulic operation system is abnormal according to the second data, wherein the method comprises the following steps:
Judging whether the pressure value of a downstream monitoring point exists in the front section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream changes of the pressure is larger than the pressure value of an upstream adjacent monitoring point at the same moment according to the fourth comparison result, and/or whether the pressure value of a downstream monitoring point exists in the rear section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream changes of the pressure is larger than the pressure value of an upstream adjacent monitoring point at the same moment, and/or whether the pressure difference between the front section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream changes of the pressure and the rear section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream changes of the pressure is larger than the preset pressure difference, and/or whether the pressure difference between the front section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream changes of the pressure is larger than the preset pressure difference;
And determining that the hydraulic operation system is abnormal when the pressure value of a downstream monitoring point exists in the front section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream change of the pressure or the pressure value of a downstream monitoring point exists in the rear section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream change of the pressure is larger than the pressure value of an upstream adjacent monitoring point at the same moment or the pressure difference between the front section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream change of the pressure and the rear section of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream change of the pressure is larger than the preset pressure difference change rate.
For example, as heat is absorbed from the environment, the liquid hydrogen continuously vaporizes in the vaporizer, raising the temperature and pressure, and also raising the buffer tank pressure, without the concomitant rise in the outlet pressure of the hydraulic pump in the case of devices installed that can block the free diffusion of pressure and/or cause a change in pressure upstream and downstream. At this time, there may be a case where the hydraulic pump outlet pressure is low, the carburetor pressure is equal to the surge tank pressure and higher than the hydraulic pump outlet pressure. At this time, whether the system pressure is normal or not cannot be judged according to the complete upstream and downstream pressure of the system. Therefore, when the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream change of the pressure is installed, other judging rules are added, and whether the system is abnormal or not can be judged according to the upstream-downstream relation of the front-stage flow of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream change of the pressure and the upstream-downstream relation of the rear-stage flow of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream change of the pressure, and whether the pressure of the downstream monitoring point is larger than the pressure of the upstream adjacent monitoring point or not can be judged independently according to whether the pressure difference between the front and the rear of the device capable of blocking the free diffusion of the pressure and/or causing the upstream and downstream change of the pressure is larger than the preset pressure difference or not.
It should be noted that, based on the above logic rule, the location of the potential failure point of the system may also be determined.
When the pressure value distribution conditions of different monitoring points at the same time are not equal or gradually decreased according to the upstream and downstream sequence pressure values, determining the monitoring point with the lowest pressure value in the monitoring points; and when the monitoring point with the lowest pressure value is the middle monitoring point of each monitoring point sequence, indicating that the monitoring point with the lowest pressure value is a leakage point.
Further, the pressure change rate of the monitoring point with the lowest pressure value is calculated, and the alarm level is determined according to the pressure change rate. When the pressure change rate is larger than the preset change rate, judging that the pressure leakage is larger, and performing interlocking to close the equipment or close the valves before and after the monitoring point while alarming.
The beneficial effects of this embodiment lie in: and directly comparing the pressure values of different monitoring points at the same time without presetting a standard pressure value interval of each monitoring point, when the pressure value sequence of each monitoring point does not meet the rule that the pressure values of the upstream and downstream sequences are equal or are gradually decreased, determining that the current system is abnormal, and determining the position of the leakage point according to the pressure value sequence of each monitoring point.
In one embodiment, the method may also be implemented as steps D4-D5 as follows:
In step D4, when the condition that the pressure value of the downstream monitoring point is larger than the pressure value of the upstream adjacent monitoring point at the same moment does not exist, judging whether the pressure value of each monitoring point at the same moment is in a standard pressure interval corresponding to each monitoring point;
In step D5, when there is a pressure value that is not within the standard pressure interval corresponding to the monitoring point, it is determined that there is an abnormality in the hydraulic operating system.
In the embodiment, when the condition that the pressure value of the downstream monitoring point is larger than the pressure value of the upstream adjacent monitoring point at the same moment does not exist, comparing the pressure value of each monitoring point at the same moment with the standard pressure interval of the moment corresponding to each monitoring point, and judging whether the pressure value is in the standard pressure interval corresponding to each monitoring point or not;
When the pressure value which is not in the standard pressure interval corresponding to the monitoring point exists, determining that the hydraulic operation system is abnormal, and sending out a high-pressure alarm prompt for the monitoring point. Further, when the difference between the pressure value of the other pressure monitoring points and the maximum value of the standard pressure interval is smaller than a seventh preset value, determining that the overall pressure of the system is higher; at this time, a high-pressure alarm prompt is sent to the system, and the hydraulic operating system is controlled to lock and stop the upstream pressure source. In addition, when the pressure difference between the monitoring point with the high-pressure alarm and the pressure monitoring point adjacent to the downstream exceeds an eighth preset value, it is determined that equipment or a pipeline behind the monitoring point with the high-pressure alarm is blocked or a valve is abnormal, an alarm reminding of abnormality after the monitoring point is sent out, and if the pressure of the monitoring point with the high alarm is larger than a larger ninth preset value (> eighth preset value), an upstream pressure source is locked, and when the pressure reaches a venting pressure, venting and pressure relief are started.
The beneficial effects of this embodiment lie in: and determining whether an abnormality occurs according to the pressure value of the monitoring point, further determining the position of the abnormality, and automatically taking measures to prevent danger, thereby ensuring the safety of the hydraulic operating system.
In one embodiment, the above step S103 may also be implemented as steps E1-E7 as follows:
In step E1, judging whether the pressure difference value of each monitoring point and the standard curve corresponding to each monitoring point at the same time point is larger than a first preset value or not according to a first comparison result;
In step E2, when the pressure difference value between the pressure value of each monitoring point and the same time point of the standard curve corresponding to each monitoring point is not greater than a first preset value, judging whether a numerical value point with the difference value greater than a second preset value exists in the pressure curves of adjacent periods of the same monitoring point according to a second comparison result;
In step E3, when no numerical point with a difference value greater than a second preset value exists in the pressure curves of the adjacent periods, judging whether a numerical point with a difference value greater than a third preset value exists in the pressure curve of the current period and the pressure curve of the initial period of the same monitoring point;
In step E4, when there is no numerical point with a difference value greater than a third preset value in the pressure curve of the current period and the pressure curve of the initial period of the same monitoring point, judging whether the difference value of the volumetric efficiency of different periods is greater than a fourth preset value;
in step E5, when the difference value of the volumetric efficiency in different periods is not greater than a fourth preset value, judging whether the condition that the pressure value of the downstream monitoring point is greater than the pressure value of the upstream adjacent monitoring point at the same time exists;
In step E6, when the condition that the pressure value of the downstream monitoring point is greater than the pressure value of the upstream adjacent monitoring point at the same moment does not exist, judging whether the pressure value of each monitoring point at the same moment is in the standard pressure interval corresponding to each monitoring point;
In step E7, when the pressure values of the monitoring points at the same time are within the standard pressure interval corresponding to the monitoring points, it is determined that no abnormality occurs in the hydraulic operating system.
In this embodiment, multiple conditions of abnormal system occurrence are monitored and excluded one by one, and whether the abnormal system occurrence is determined by judging whether the difference value of the pressure value of each monitoring point and the standard curve at the same time point is smaller than a first preset value, judging whether a numerical point with the difference value larger than a second preset value exists in the pressure curve of the adjacent period of the same monitoring point, judging whether the difference value of the pressure curve of the current period of the same monitoring point and the pressure curve of the initial period of the same monitoring point is larger than a third preset value, judging whether the difference value of the volumetric efficiency of different periods is larger than a fourth preset value, judging whether the distribution condition of the pressure values of the different monitoring points at the same moment is sequentially decreased according to an upstream-downstream sequence, and judging whether the pressure value of the monitoring points at the same moment is in a standard pressure interval corresponding to the monitoring points under the condition that all the conditions are met.
In view of the foregoing, the present application provides a general embodiment to specifically describe a specific judging process: in this embodiment, when the pump is initially calibrated, the pump is operated in a calibrated state, each pressure measurement point on the pump and the upstream and downstream process systems records real-time pressure data of each pressure measurement point under each calibration condition, and a most representative set of data (such as a median value) is taken as a standard curve value by adopting a statistical method. And calculating the distribution characteristic (such as normal distribution) of the calibration data according to a statistical method, and determining a reasonable range (such as 3 times standard deviation) according to the distribution characteristic. Defined within this reasonable range as the normal interval of data. A certain safety margin (for example, 3σ) is reserved outside the normal interval, the data (for example, probability <6σ) which is further outside is defined as abnormal data, the interval is defined as an abnormal interval, and an action interval of interlocking protection is further defined outside the abnormal interval. The calibration state is completed. And after the pump is turned to an actual running state, selecting a corresponding standard curve according to the running state of the pump at the moment to compare in real time. If the difference between the actual pressure value and the standard value exceeds 6 times of standard deviation, the system is judged to be abnormal. An alarm is given. And then above a certain set range, the interlocking stops the pump.
It is to be understood that this embodiment is only an example, and the execution sequence of each determination mechanism may be different from each other, and those skilled in the art may flexibly adjust the execution sequence of each determination mechanism according to the need.
