Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete description of the technical solutions of the embodiments of the present invention will be given below with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are partial embodiments of of the present invention, rather than all embodiments.
Fig. 1 is a schematic flow chart of a system health assessment method according to an embodiment of the present invention, as shown in fig. 1, the method includes:
and step 110, obtaining system operation results of a plurality of time points in a preset time period, wherein the system operation results are determined based on the operation characteristic values of the system to be evaluated and a preset limit.
Specifically, the system to be evaluated is a system that needs to be subjected to health evaluation, the system operation result is a result obtained by evaluating the operation condition of the system to be evaluated at a certain time point, the system operation result may be in a form of a score, may also be levels of several operation state levels divided in advance, may also be the number of operation characteristic values that exceed a preset limit, and the like, and the embodiment of the present invention is not particularly limited to this.
The operation characteristic value is a characteristic that the acquired system to be evaluated reflects the system operation state in the operation process, namely, a value of the operation characteristic, and if the system to be evaluated is a generator set system, the operation characteristic can be motor rotation speed, output voltage, output power, temperature and the like, the preset limit is a preset limit, the operation characteristic corresponds to a preset limit limit, different operation characteristics correspond to different preset limits, for example, the motor rotation speed corresponds to a preset limit of the motor rotation speed, the temperature corresponds to a preset limit of the temperature, and the preset limit is a maximum value or a minimum value of the operation characteristic, and by comparing the operation characteristic value with the preset limit, whether the operation characteristic value is in a normal state or not can be determined, and then the system operation result is determined.
The preset time period is time periods backward pushed from the current time, the length of the time period is preset, for example, the preset time period is 1 month, the current time is 8 months and 12 days, and the preset time period is 7 months and 12 days to 8 months and 12 days.
And step 120, determining the health state of the system based on the system operation results of a plurality of time points in a preset time period.
Specifically, after obtaining the system operation results at a plurality of time points within the preset time period, the health status of the system to be evaluated is evaluated based on each system operation result to obtain the system health status.
Compared with the prior art that the system health state is determined only by means of real-time operation characteristic values and preset limits, the method provided by the embodiment of the invention filters short-term fluctuation factors in operation, and the obtained system health state is more accurate and reliable.
Based on the embodiment, the method for determining the system operation result comprises the steps of collecting the operation characteristic value of the system to be evaluated at any time point in a preset time period, determining the system score grade based on the operation characteristic value and the preset limit, and determining the system operation result of the time period based on the operation characteristic value, the preset limit and the system score grade.
Specifically, the collection of the operation characteristic value may be realized by each sensing device preset on the system to be evaluated, and after the data collection is completed, the sensing device transmits the collected data in a wired or wireless communication manner, so that the server can receive the collected data and obtain the operation characteristic value through analysis and processing.
A plurality of system scoring levels are preset, different system scoring levels correspond to different comparison conditions of operation characteristic values and preset limits, for example, each operation characteristic value is lower than a corresponding preset 0 limit, the corresponding system scoring level D1, a part of operation characteristic values are lower than a corresponding preset limit, a part of operation characteristic values are higher than a corresponding preset limit, the corresponding system scoring level D2, each 2 operation characteristic value is higher than a corresponding preset limit, the corresponding system scoring level D3. for example, the preset limit includes an alarm limit and a hazard limit, an alarm limit is lower than a hazard limit, each operation characteristic value is lower than 80% of a corresponding alarm limit, the corresponding system scoring level D , a part of operation characteristic values are lower than 80% of a corresponding alarm limit, a part of operation characteristic values between 80% and 100% of a corresponding alarm limit, the corresponding system scoring level D72, a part of operation characteristic values between the corresponding system scoring level D and a corresponding hazard score limit, and a corresponding hazard score between the corresponding hazard score limit, and a part of a corresponding hazard score limit, and a corresponding hazard score limit, a corresponding hazard score between 80% of a corresponding hazard characteristic value between the corresponding hazard limit, and a corresponding hazard score limit exists between the corresponding hazard score limit, and a part of the corresponding hazard score limit, and a corresponding hazard score between the corresponding hazard score .
In different system scoring levels, the operation system results obtained based on the operation characteristic values and the preset limit are different, different system scoring levels can give different rating score ranges to the system operation results, different system scoring can also provide different rating score references for the system operation results, and the like.
According to the method provided by the embodiment of the invention, the operation characteristic value of any time point is collected, the system operation result of the time point is determined, and a historical basis is provided for determining the health state of the system at the subsequent time.
Based on any embodiment, the method further includes, before step 110, determining a latest repair time, and if the latest repair time is earlier than a preset time, setting a time interval between the preset time and the current time as the preset time interval, otherwise, setting a time interval between the latest repair time and the current time as the preset time interval.
The method comprises the steps of obtaining current time, obtaining latest repair time, wherein the latest repair time is the time for repairing the system to be evaluated for times, the preset time is the starting time of a preset time period, and the time closer to the current time is selected from the latest repair time and the preset time to be used as the starting time of the preset time period, so that the preset time period is determined.
For example, the current time is 6 months and 12 days, the latest repair time is 5 months and 14 days, the preset time is two months before, namely 4 months and 12 days, and the preset time interval is determined to be 5 months and 14 days to 6 months and 12 days; for another example, the latest repair time is 3 months and 14 days, the preset time is two months before, i.e., 4 months and 12 days, and the preset time period is determined to be 4 months and 12 days to 6 months and 12 days.
The method provided by the embodiment of the invention determines the preset time interval through the latest repair time, thereby avoiding the process of mixing the system operation result before the system to be evaluated is repaired into the determination process of the system health state and providing the reliability of the system health evaluation.
Based on any embodiment, in the method, the step 120 specifically includes determining weights of system operation results at a plurality of time points according to a time sequence of the system operation results, wherein the closer the time point of the system operation result is, the higher the weight of the system operation result is, determining a fused system operation result based on each system operation result and the weight thereof, and determining a system health state based on the fused system operation result.
Specifically, the chronological order of the plurality of system operation results in the preset time period obtained in step 110 exists, and the closer the time point of the system operation result is to the current time, the closer the system operation state is to the current time, and the higher the weight occupied when the plurality of system operation results are fused is. Therefore, the weights may be determined according to the time sequence of the system operation results, for example, three system operation results within a preset time period, which are the system operation results A, B, C arranged in the order from the near to the far from the current time, and the corresponding weights are 50%, 30%, and 20%, respectively.
The fusion system operation result is a weighted sum of the system operation results in a preset time period. And after the operation result of the fusion system is obtained, the health state of the system can be determined.
Based on any embodiment, the method includes the steps of collecting operation characteristic values of a system to be evaluated at any time point in a preset time period, performing spectrum analysis on the operation characteristic values to generate an operation data report, configuring a system 3D model corresponding to the system to be evaluated based on the operation characteristic values and/or the operation data report, and sending an alarm signal and changing the color of a position corresponding to the operation characteristic values in the system 3D model if the operation characteristic values are larger than a preset limit.
Specifically, the system 3D model corresponding to the system to be evaluated is a pre-constructed model which can be monitored by operation and maintenance personnel in real time, and can simulate a real system to be evaluated and reflect the running state of the system to be evaluated in time.
In addition, the operation characteristic value and the preset limit are judged, if the operation characteristic value is larger than the preset limit, an alarm signal is sent out, and the color of the position corresponding to the operation characteristic value in the system 3D model is changed, for example, if the operation characteristic value is smaller than the preset limit, the color of the corresponding position is green if no alarm signal exists, if the operation characteristic value is larger than the preset limit in the limit and smaller than the dangerous limit, the color of the corresponding position is yellow, and if the operation characteristic value is larger than the dangerous limit in the limit, the color of the corresponding position is red.
The method provided by the embodiment of the invention realizes the three-dimensional visual state monitoring of the system to be evaluated and provides an intuitive monitoring approach for operation and maintenance personnel.

Typically, the operating characteristic is expressed as a peak-to-peak value.
The peak-peak value of the vibration value and the peak-peak value of the oscillation value are calculated by adopting an average time interval method, namely, the recorded vibration and oscillation time domain waveform graph is partitioned, the difference between the maximum value and the minimum value of sampling point data in each partition is the peak-peak value of the partition, the average value of the peak-peak values of all the partitions is the peak-peak value of the time domain waveform graph, every partition time interval at least comprises 1 complete vortex band period, and for a machine set which does not have a vortex band or a vortex band period which is less than the time of 4 revolutions of the machine set, the partition time interval time is preferably the time of 4 revolutions of the machine set.
The confidence coefficient of the water conservancy pumping station system can be preset, for example, the confidence coefficient can be set to 97%, and the peak-peak value of the pressure pulsation amplitude can be represented by an absolute value △ H (unit kPa) or a relative value △ H/H (unit%).
Based on any embodiment, the method further includes sending a replacement prompt if the accumulated time of the components in the system to be evaluated exceeds the preset service life.
