The first concentrator is any concentrator in a remote meter reading system, regular basic performance detection is carried out on the first concentrator in order to prevent the concentrator from generating communication faults, the basic performance detection comprises but is not limited to wiring detection, appearance display detection and communication card detection, the detection result is a first detection result, if the first detection result has problems, corresponding maintenance is carried out, and after the basic performance faults are eliminated, the communication faults are detected and checked on the basis of the first detection result.
The communication faults of the concentrators comprise uplink communication faults and downlink communication faults, and uplink communication link information and downlink communication link information are obtained according to the first concentrator. The uplink communication link information comprises a first master station to first concentrator communication link; the downlink communication link information comprises a first concentrator, a first collector set and an intelligent metering device. The first collector set comprises a plurality of collectors and is a data collection device set which is connected with the first concentrator and is used for collecting data of the intelligent metering instrument, storing and uploading data or downloading an execution command to the intelligent metering instrument.
Obtaining the uplink communication link information and the downlink communication link information based on big data. The uplink communication link information comprises information of a plurality of concentrators connected with the first main station, a connection mode of the concentrators and the first main station, and historical fault data and maintenance data of uplink communication faults of the concentrators. The downlink communication link information comprises a collector set connected with the first concentrator, a communication mode of the first concentrator and the collectors, historical fault data and maintenance data of the first concentrator when downlink communication faults occur, and the like. The acquisition of the uplink communication link information and the downlink communication link information of the first concentrator lays a foundation for analyzing the communication fault of the first concentrator.
Step S300: the method comprises the steps of obtaining a first concentrator set which a first master station belongs to, and carrying out real-time region division on the first concentrator set through a first region division model to obtain a first real-time region ID which the first concentrator belongs to;
further, step S300 in the embodiment of the present application further includes:
step S310: obtaining a first data acquisition period, and obtaining a historical maintenance data set of the first concentrator set based on the first data acquisition period;
step S320: obtaining identification data identifying concentrator area ID information based on the historical repair data set;
step S330: training a neural network model based on the historical repair data set and the identification data to obtain the first region segmentation model.
Specifically, since the first master station belongs to the first concentrator set which is a plurality of concentrators, in order to improve the efficiency of the upstream communication fault detection of the first concentrator, the first concentrator set may be partitioned, and the first area division model may partition the first concentrator set according to the historical fault and maintenance information of the concentrator.
The first region segmentation model is a model trained on the basis of a neural network and used for performing region segmentation on the concentrator. Because the concentrator is suitable for different years, and historical data is various, therefore predetermine first data acquisition cycle for gather the data that have certain timeliness, can set for according to fixed fault maintenance time. And docking fault and maintenance data of the first concentrator set based on the first data acquisition period to obtain the historical maintenance data set. The historical maintenance data set comprises maintenance fault reasons and maintenance fault occurrence times, the historical maintenance data set is divided into a training set and a testing set, identification data is obtained according to the training set of the historical maintenance data, the identification data is used for identifying the area ID information of the concentrator, and the concentrator with the same area ID has the fault reasons and the fault occurrence times with higher similarity. And training a neural network model through the training set of the historical maintenance data and the identification data to obtain the first region segmentation model, inputting the test set into the first region segmentation model, and obtaining a first real-time region ID to which the first concentrator belongs.
Since the previous fault detection result of the first concentrator set is different in each communication fault detection, the obtained area ID is different from the area ID detected by the previous fault by performing area division through the previous historical data, and is called as a real-time area ID. The first real-time area ID to which the first concentrator belongs is obtained, the accuracy of area division can be improved through real-time partitioning, and the method is favorable for laying a foundation for fault interval detection in the process of uplink communication fault detection.
Step S400: obtaining a first uplink communication link signal acquisition result based on the first real-time zone ID;
further, step S400 in the embodiment of the present application further includes:
step S410: generating first signal transmission period information based on the first real-time area ID;
step S420: according to the first signal sending period information, the first master station sends a first confirmation signal to the first concentrator;
step S430: and acquiring a reply signal based on the first confirmation signal to obtain a first uplink communication link signal acquisition result.
Specifically, the first concentrator is a target concentrator to be detected, and the uplink communication detection area of the concentrator is reduced to the concentrator set corresponding to the first real-time area ID through the allocated first real-time area ID. And confirming the network signal of the distribution area of the concentrator in the ID according to the first real-time area ID, generating first signal transmission period information according to the strength of the network signal, generally setting the first signal transmission period information to be 30 minutes, and shortening the network signal strength to be 15 minutes, 10 minutes and the like. And according to the first signal sending period information, the first master station sends a confirmation signal to the concentrator in the first real-time area ID, wherein the first confirmation signal is sent to the first concentrator and is used for confirming the running state and the online state of the first concentrator. And collecting a reply signal in real time, if the reply signal is received, the first concentrator is not abnormal, and if the reply signal is not received in real time, the first signal sending period needs to be changed, and whether the abnormality exists is confirmed again.
By dividing the area of the first concentrator set under the first master station, performing priority fault detection on the concentrator set including the first concentrator according to the first real-time area ID, and determining the first signal transmission period through the first real-time area ID, the time for confirming the running state and the online state of the first concentrator can be shortened, thereby improving the efficiency of uplink communication link fault detection.
Step S500: performing real-time region division on the first collector set through a second region division model to obtain a first collector set division region ID set;
step S600: obtaining a first downlink communication link signal acquisition result based on the first collector set partition area ID set;
specifically, the second region segmentation model is a neural network model, and is a model for performing region segmentation on the first collector set connected to the first concentrator. Similar to the training process of the first region segmentation model, data (including but not limited to maintenance fault reasons, fault occurrence times and the like) maintained by the last collector is collected and subjected to data division into a training set and a test set, and the division proportion can be set according to the data volume. And identifying the training set data to obtain identification data for identifying the area ID of the collector. And training the neural network model through the training set data and the identification data to obtain a second region segmentation model.

Step S700: and performing abnormal interval detection on the communication fault of the first collector based on the first uplink communication link signal collection result and the first downlink communication link signal collection result.
Further, as shown in fig. 2, step S700 in the embodiment of the present application further includes:
step S710: if the first confirmation signal does not receive a reply signal, reducing the first signal sending period to obtain a second signal sending period;
step S720: if the reply signal is still not received, continuing to reduce the second signal sending period until an Mth signal sending period is obtained, wherein the Mth signal sending period is the shortest signal sending period;
step S730: and if an Mth confirmation signal is sent according to the Mth signal sending period and a reply signal is not received yet, judging that the first collector has an uplink communication fault.
Specifically, according to the analysis of the first uplink communication link signal acquisition result and the first downlink communication link signal acquisition result, the communication fault information of the first concentrator can be subjected to complete communication link fault detection, so that the fault detection result is specially maintained, the field troubleshooting time of maintenance personnel is reduced, and the communication fault detection efficiency is improved.
Further, fault detection is performed on the signal acquisition result of the first uplink communication link, if the first master station sends the first acknowledgement signal to the first concentrator, the first acknowledgement signal does not receive the reply signal, and it cannot be determined that the state of the first concentrator is abnormal, the first signal sending period is required, the signal sending period is continuously shortened, and a new signal sending period is continuously obtained, that is, the second signal sending period is up to the mth signal sending period, where the mth signal sending period is the shortest signal sending period and cannot be shortened any more. And continuously sending signals, and if the signals are still the reply signals of the first concentrator until the Mth signal sending period, judging that the first collector has an uplink communication fault, and the concentrator is offline and cannot upload data to the first master station. Through constantly shortening the signal sending period, scientific anomaly detection can be carried out on the signal acquisition result of the first uplink communication link, and the scientific reliability of the detection result is ensured.
Further, step S600 in the embodiment of the present application further includes:
step S610: obtaining a first meter reading signal set based on the first collector set partition area ID set;
step S620: after the first meter reading signal set is verified, sending a first meter reading signal according to the ID of the divided area of the first collector set;
step S630: and acquiring a reply signal of the first meter reading signal to obtain a signal acquisition result of the first downlink communication link.
Specifically, after the divided region ID set of the first collector set is obtained, meter reading signals are sequentially sent according to the divided region ID set, and the sent meter reading signals are the first meter reading signal set. Because the collector replies the exception to the signal sent by the concentrator partly because of the communication fault between the collector and the intelligent instrument, and partly because of the error in the signal sent by the concentrator, the following steps are exemplified: the meter number to be read in the meter reading signal sent by the concentrator is different from the actual meter number, and the concentrator is not loaded with meter reading time periods and the like. And checking the first meter reading signal, after confirming that the meter reading signal is correct, sequentially sending the first meter reading signal according to the ID of the first collector set partition area, collecting a reply signal, and taking the reply signal as a signal collection result of the first downlink communication link. Through meter reading signal verification, communication faults caused by signal errors issued by the concentrator are reduced, and the efficiency of automatic fault detection is improved.
Further, step S700 in the embodiment of the present application further includes:
step S740: classifying the first downlink communication link signal acquisition result according to an abnormal result analysis support vector machine to obtain a first abnormal result and a second abnormal result;
step S750: acquiring first abnormal collector region ID information of the first abnormal result;
step S760: and according to the area ID information of the first abnormal collector, overhauling the response error problem of the first meter reading signal.
Further, as shown in fig. 3, step S700 in the embodiment of the present application further includes:
step S741: acquiring second abnormal collector region ID information of the second abnormal result;
step S742: according to the abnormal collector region ID information of the second abnormal result, performing distribution region analysis on the abnormal intelligent metering instrument to obtain a concentration analysis result of the first ID distribution region;
step S743: if the concentration analysis result meets a first preset concentration, obtaining a first abnormal detection result;
step S744: and if the concentration analysis result meets a second preset concentration, obtaining a second abnormal detection result.
Specifically, the support vector machine is a generalized linear classifier for binary classification of data in a supervised learning mode, and a decision boundary of the generalized linear classifier is an optimal hyperplane for solving learning samples. The support vector machine is a classifier with sparsity and robustness. The abnormal result analysis support vector machine is obtained by training historical collected data of a first downlink communication link signal, and can distinguish that an instrument subordinate to a collector does not reply to a concentrator and reply content errors.
And obtaining the first abnormal result and the second abnormal result, wherein the first abnormal result is that the content is wrong to reply, and the second abnormal result is that the reply is not carried out. And if the first abnormal result is contained in the first downlink communication link signal acquisition result, matching the corresponding first abnormal collector region ID information according to the first abnormal result, and performing overhaul on the first meter reading signal response error problem by maintenance personnel according to the first abnormal collector region ID information.
And if the signal acquisition result of the first downlink communication link comprises the second abnormal result, the second abnormal result is that the intelligent metering instrument subordinate to the acquisition device does not reply. And matching the corresponding second abnormal collector region ID information according to the second abnormal result, positioning the intelligent metering instrument which does not reply according to the non-reply signal in the region, and determining the actual geographic position of the intelligent metering instrument. And analyzing the distribution area of the abnormal intelligent metering device based on the actual geographic position. The distribution of the abnormal intelligent metering instruments is dispersed, the distribution of the abnormal intelligent metering instruments is concentrated, and the time for manually judging the problems can be greatly reduced if the distribution condition of the abnormal intelligent metering instruments can be analyzed.
Concentration is understood to be the degree of concentration or closeness of distribution of the status locations, and may be obtained by density analysis within a certain range. The method comprises the steps of obtaining a first preset concentration degree, wherein the first preset concentration degree represents that abnormal intelligent metering instruments are densely distributed, and when the concentration degree analysis result meets the first preset concentration degree, a first abnormal detection result is obtained and comprises that the distance between the intelligent metering instruments which do not reply is short. According to the fact that the intelligent metering instrument which does not reply is close in distance and combined with the maintenance experience of related professionals, the abnormal reason is probably the fact that interference sources exist in the periphery. And obtaining a second abnormal detection result when the concentration analysis result meets the second preset concentration, wherein the second abnormal detection result comprises that the distances of the intelligent metering instruments which do not reply are relatively dispersed, and the obtained abnormal reason is probably the version problem of the meter reading system according to the maintenance experience of related professionals, for example, the second generation system often cannot read the instruments at the tail end, and the instruments which cannot read (do not reply) are relatively dispersed.
The first downlink communication link signal acquisition result is accurately divided into a first abnormal result and a second abnormal result through a support vector machine, the second abnormal result is further analyzed through a preset concentration degree, the abnormal detection result can be intelligently analyzed, the working intensity of maintenance personnel is reduced, and the downlink communication link fault monitoring efficiency of the concentrator is improved.
