In order to illustrate the technical scheme of the application, the following description is made by specific examples.
The development of big data and internet of things technology makes the idea of remotely detecting the operation state of equipment more and more accepted, and when the operation data deviate from the operation standard (threshold or limit value) is found, the operation data is sometimes caused by abnormal operation of the equipment, but sometimes caused by the change of the operation standard due to the continuous change of the operation condition of the equipment.
The device operation standard generally complies with some fixed threshold or limit value set by the device manufacturer, but for some operation parameter standard, a relative evaluation standard or dynamic evaluation standard can be introduced, wherein the standard is aimed at the same monitoring amount of the same device under the same operation environment (geography, position and working condition), and the evaluation standard mainly comprises two parts, namely an evaluation reference value and a confidence interval.
The application provides a monitoring method of equipment operation state based on time sequence and neural network algorithm by combining big data technology.
Referring to fig. 1, a specific embodiment of a method for monitoring an operating state of a device according to the present application is shown. In this embodiment, the method specifically includes the following steps:
step 101: and acquiring measurement point data of the equipment according to the historical data of the equipment.
The device may be any device in the energy station that gathers all or a desired historical data information based on the determined target device.
The measurement point data related in the embodiment can be implemented by using a measurement point data acquisition module. The measuring point data acquisition module is mainly used for acquiring measuring point data of the equipment according to historical data of the equipment. The station data acquisition module may include a preprocessing unit and a station data acquisition unit, and the preprocessing unit and the station data acquisition unit may be connected in series.
Specifically, the preprocessing unit may remove repeated data and/or abnormal data that may occur, and then the measuring point data obtaining unit may perform preset step grouping on the time series data. Whereby station data of the device is obtained.
Step 102: and processing the measurement point data by adopting a time sequence model to obtain a predicted value of the equipment at a preset moment.
The time sequence algorithm is a relatively mature algorithm capable of realizing prediction aiming at time sequence data, and the data information adopted in the embodiment is ordered according to time, so that the time sequence algorithm is suitable for prediction by adopting a time sequence method. The time series model may include an autoregressive model (Autoregressive model, AR), an autoregressive moving average model (Autoregressive moving average model, ARMA), a differentially integrated moving average autoregressive model (Autoregressive integrated moving average, ARIMA), and the like. In this embodiment, it may be preferable to predict the predetermined time of the target device using a differentially integrated moving average autoregressive model (Autoregressive integrated moving average, ARIMA). The measurement point data involved in this step may be implemented using a predicted value acquisition module.
It should be understood that the differential integrated moving average autoregressive model is one of the preferred models of the present embodiment, and of course, other time series models or algorithms are also possible, and are not limited herein.
Step 103: and processing the measurement point data and the predicted value by adopting a reverse error neural network to obtain a residual predicted value.
The BP (back propagation) neural network is a multi-layer feedback neural network, is one of the most widely used neural networks, has strong nonlinear mapping capability and self-learning and self-adapting capability, and can include a multi-layer feedforward neural network and a reverse error neural network.
The residual prediction value involved in the present embodiment may be implemented by using a residual prediction value acquisition module. The residual prediction value obtaining module is used for carrying out operation processing on the difference value between the prediction value and the operation data, namely the initial residual value, so as to obtain a residual prediction value. The residual prediction value acquisition module may include an initial residual value acquisition unit and a residual prediction value acquisition unit.
Specifically, the initial residual value obtaining unit may obtain, according to the measurement point data, operation data of the device at the preset time, so as to obtain an initial residual value; the residual prediction value obtaining unit is used for processing the initial residual value by using a reverse error neural network to obtain a residual prediction value.
Step 104: and acquiring an evaluation reference value according to the predicted value and the residual error predicted value.
And based on the fact that the residual predicted value is real (including rational number and irrational number), the residual predicted value is signed, so that the predicted value and the residual predicted value are added to obtain an evaluation reference value.
The measurement point data involved in this step can be realized by an evaluation reference value acquisition module.
Step 105: and determining a confidence interval of the equipment at the preset time according to the measurement point data of the equipment and the evaluation reference value.
The evaluation reference value of the equipment operation is only a reference value, the reasonable operation of the equipment is theoretically an interval, the operation data in the interval are all reasonable ranges, and otherwise, the operation data are abnormal.
The measurement point data involved in this step may be implemented using a confidence interval determination module. The confidence interval determining module is mainly used for calculating the measurement point data and the evaluation reference value of the equipment to obtain the average value and standard deviation of the measurement point data so as to determine a confidence interval. The confidence interval determining module may include an average value acquiring unit, a standard deviation acquiring unit, and a confidence interval acquiring unit.
Specifically, the average value obtaining unit may obtain an average value based on the measurement point data, the standard deviation obtaining unit may obtain a standard deviation based on the average value, and the confidence interval obtaining unit may obtain a confidence interval based on the standard deviation and the evaluation reference value.
Step 106: and determining the running state of the equipment according to the running data of the equipment at the preset time and the confidence interval.
Based on the operational data (or referred to as actual values) and the confidence interval of the device at the preset time, the real-time operational state of the device can be judged and determined.
The measurement point data involved in this step may be implemented using an operational state determination module.
According to the technical scheme, the beneficial effects of the embodiment are as follows: the method combines the big data technology, is based on the combination of a time sequence model and a reverse error neural network algorithm, can monitor and acquire the actual running state of the target equipment in real time under a remote condition, and combines the reasonable confidence interval range of the running of the equipment, thereby effectively overcoming the defect of inaccurate prediction of the actual running state of the equipment in the prior art, and simultaneously being beneficial to the scheduling optimization of the follow-up work by an accurate prediction result. The monitoring method provided by the embodiment is simple in integral operation, ensures accuracy, convenience and rapidness of prediction, improves integral processing speed, and saves processing resources.
Fig. 1 shows only a basic embodiment of the method according to the application, on the basis of which certain optimizations and developments are made, but other preferred embodiments of the method can also be obtained.
Fig. 2 shows another embodiment of the method for monitoring the operation state of the device according to the present application. The present embodiment is further described with reference to specific application scenarios based on the foregoing embodiments. The method specifically comprises the following steps:
step 201: preprocessing the acquired historical data of the equipment to acquire preprocessed time series data, wherein the preprocessing comprises removing repeated data and/or abnormal data in the historical data.
When the historical data are arranged, the data can be collected as much as possible, so that the accuracy of prediction can be ensured.
The preprocessing involved in this step may be implemented using a preprocessing unit of the station data acquisition module.
Step 202: grouping the time series data according to a preset step length, and calculating the average value of each group of data to obtain the measuring point data of the equipment.
The historical data set refers to historical standard data of the operation of the equipment, and according to a statistical theory, the average value of the sample can be regarded as a theoretical average value, namely a theoretical standard value of the operation of the equipment. The measurement point data adopted in this embodiment may be understood as a group of data sequences of every 10 pieces of data according to time sequence, for example, the preset step length, and the average value of the data is calculated as new measurement point data. It should be understood that 5 pieces of data, 20 pieces of data, 99 pieces of data may be used as a set of data sequences, and are not limited herein.
The selection of the data measuring points in the historical data set is related to the attribute of the equipment to be monitored, and if the boiler exhaust gas temperature is to be observed to be normal or not, the boiler exhaust gas temperature data is required to be input. This can also be understood as follows: the measurement point data is the data of a certain attribute of the target equipment. It should be understood that the data measurement point data about the equipment attribute may be various attribute data information of the equipment such as the boiler exhaust gas temperature, exhaust gas waste heat, and the like, and is not limited herein.
The measurement point data involved in this step can be realized by using a measurement point data acquisition unit of the measurement point data acquisition module.
Step 203: and processing the measurement point data by adopting a differential integration moving average autoregressive model to obtain a predicted value of the equipment at a preset moment.
In this embodiment, it may be preferable to predict the predetermined time of the target device by using the differential integrated moving average autoregressive model. It should be understood that the differential integrated moving average autoregressive model is one of the preferred models of the present embodiment, and of course, other time series models or algorithms are also possible, and are not limited herein.
Step 204: and acquiring an initial residual value according to the measuring point data and the predicted value.

Step 205: and the reverse error neural network processes the initial residual value to obtain a residual prediction value.
The learning rule of the reverse error neural network is to continuously adjust the weight and the threshold value of the network by using the steepest descent method through back propagation, so that the square sum of errors of the network is minimized.
In order to further improve the prediction accuracy, a reverse error neural network algorithm is adopted to predict nonlinear residuals of measurement point data (actual values) in historical data and predicted values of the time sequence, so that the predicted values of the time sequence are corrected, and finally a final predicted result is output. It should be understood that the inverse error neural network algorithm is one of the preferred algorithms in this embodiment, and of course, other neural network algorithms are also possible, which is not limited herein.
And the predicted value is differenced with the operation data and is used as input data of the reverse error neural network, so that feedback of a differential integration moving average autoregressive model algorithm is realized, and a predicted result is more accurate.
The residual prediction value involved in this step may be implemented by a residual prediction value acquisition unit of the residual prediction value acquisition module.
Step 206: and in the step of acquiring an evaluation reference value according to the predicted value and the residual predicted value, the evaluation reference value is the sum of the predicted value and the residual predicted value.
Step 207: and obtaining the average value of the measuring point data according to the measuring point data of the equipment.
The average value of the measurement point data may be: every 10 data are used as a group of data sequences according to time sequence, and the average value is calculatedIt should be understood that 5 pieces of data, 20 pieces of data, 99 pieces of data may be used as a set of data sequences, and are not limited herein.
The average value involved in this step may be implemented using an average value acquisition unit of the confidence interval determination module.
Step 208: and acquiring the standard deviation of the measuring point data according to the average value of the measuring point data.
Based on the average value and the measurement point data, the standard deviation σ of the measurement point data can be obtained.
The standard deviation involved in this step may be implemented using a standard deviation acquisition unit of the confidence interval determination module.
Step 209: and determining a confidence interval of the equipment at the preset moment according to the evaluation reference value and the standard deviation of the measurement point data.
In this embodiment, a 3 sigma manner is adopted to determine a confidence interval, where the confidence interval is:
wherein ,for the reference value of the evaluation,sigma is the standard deviation of the measurement point data.
The confidence interval involved in this step may be implemented using a confidence interval acquisition unit of the confidence interval determination module.
Step 210: and determining the running state of the equipment according to the running data of the equipment at the preset time and the confidence interval.
The operating states involved in this step may be implemented using an operating state determination module.
According to the technical scheme, the embodiment has the following beneficial effects on the basis of the embodiment shown in fig. 1: the repeated data and/or abnormal data are removed by carrying out data preprocessing on the time sequence data, so that the basic data are tidier and cleaner; grouping the time series data to enable the processed data to be more similar to standard data, laying a foundation for further processing of data in the subsequent step, and improving prediction accuracy; meanwhile, according to the calculation result, the real-time running state of the equipment can be simply and rapidly calculated, and the reasonable running range can judge whether the running state of the equipment is abnormal or not.
