Detailed Description
The technical solutions of the present invention will be clearly and completely described in connection with the embodiments, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the prior art, when abnormal monitoring is performed on a wireless network signal of an intelligent terminal, the wireless network signal cannot be continuously and effectively monitored only by judging a few round trip times of test data, and the round trip time is generally directly compared with a time threshold value, so that continuous monitoring on the state of the wireless network signal is difficult to realize, and invalid judgment is easily caused by instantaneous environmental influence factors.
Referring to fig. 1, an embodiment of a first aspect of the present invention provides a method for monitoring signal anomalies in a wireless network of an intelligent terminal, including: the method comprises the steps of regularly and continuously sending test data to the intelligent terminal, completing a test period when the test data returned by the intelligent terminal are received, counting the corresponding duration of the test period and marking the duration as test time; constructing a signal test curve by taking the mark of the test period as an independent variable and the corresponding test time as the dependent variable; constructing time windows based on the identifiers of the test periods, and analyzing whether the signal test curves are abnormal in each time window; acquiring environment data corresponding to a plurality of intelligent terminals, and constructing a plurality of signal environment curves by taking the identification of a test period as an independent variable and taking the environment data as a dependent variable; and extracting signal influence factors of the abnormal time window and corresponding signal influence weights based on the plurality of signal environment curves.
According to the method, the test data are sent to the intelligent terminal in a timed and continuous mode, the test time corresponding to a plurality of test periods is obtained, and then a signal test curve is generated; analyzing a signal test curve based on a time window, and judging that the wireless network signal corresponding to the time window is abnormal when the test time is stable in the time window and no local mutation occurs; and analyzing the test time in the time period, and avoiding invalid judgment while guaranteeing the monitoring precision of the wireless network signal.
The method comprises the steps of analyzing the consistency of a signal curve segment of an abnormal time window and an environment curve segment, extracting signal influence factors according to a consistency analysis result, determining the signal influence weight of each signal influence factor according to the integral state of a first derivative, and transmitting a generated signal influence sequence to operation and maintenance personnel; the operation and maintenance personnel can rapidly extract environment sub-data affecting the wireless network signals according to the signal affecting sequence, and meanwhile, the environment sub-data are efficiently processed to ensure the strength of the wireless network signals of the intelligent terminal.
The invention constructs time windows based on the identification of the test period, analyzes whether the signal test curve is abnormal in each time window, and comprises the following steps: setting a time window according to the working strength of the intelligent terminal; extracting a signal curve segment corresponding to the time window from the signal test curve; calculating a test time mean value in the signal curve segment and a mean square error of the corresponding first derivative, wherein the test time mean value and the mean square error are respectively marked as CSJ and DJC; the abnormality evaluation coefficient YPX is calculated by the formula ypx=α×csj×exp (DJC); when the abnormality evaluation coefficient YPX is larger than the corresponding abnormality evaluation threshold, determining that the signal curve segment is abnormal; otherwise, judging that the signal curve segment is normal.
The time window is reasonably set according to the working strength of the intelligent terminal. When the working intensity corresponding to the intelligent terminal is smaller, the time window is larger; if the working strength of the intelligent terminal tends to be stable, the time windows are set at equal intervals. Each test period corresponds to a test time, and the larger the test time is, the more smooth the corresponding communication process is, and the larger the continuous test time is, the more the wireless network signal is possibly affected. It should be noted that if the returned test data is not received in one test period, the corresponding test time is set to a sufficiently large value, so that the later analysis is facilitated.
When the wireless network signal is analyzed according to the signal test curve, the invention mainly considers the variation amplitude of the test time in the time window, namely, the variation amplitude is expressed by the mean value of the test time and the mean square error of the first derivative of the signal test curve. The smaller the mean value of the test time, the better the wireless network signal, the smaller the mean square error of the first derivative, and the smaller the variation amplitude of the wireless network signal. The two are combined to comprehensively evaluate the state of the wireless network signal in the time window, so that misjudgment caused by a single factor is avoided.
The invention obtains environment data corresponding to a plurality of intelligent terminals, takes the identification (expressed by positive integer) of a test period as an independent variable, and constructs a plurality of signal environment curves by taking the environment data as the dependent variable, comprising the following steps: the intelligent terminal returns the environment data and the test data together and extracts environment sub-data in the environment data; and constructing a signal environment curve by taking the identification of the test period as an independent variable and the corresponding environment sub-data as the dependent variable.
The environmental data comprises environmental data such as temperature, humidity, wind power or air pressure which influence the wireless network signals, and the change trend of the environmental data and the environmental data is consistent when the environmental data influence the wireless signals. If the air pressure is larger, the wireless network signal is smaller, and the consistency of the wireless network signal and the wireless network signal is opposite; the consistency here does not include merely increasing or decreasing consistently. It should be noted that, because the environment data includes a plurality of environment sub-data, when a signal environment curve is established, the same intelligent terminal corresponds to a plurality of signal environment curves.
When the signal curve segments are abnormal, extracting a signal environment curve according to a corresponding time window to obtain a plurality of environment curve segments; judging whether the change trend of the signal curve segment is consistent with the change trend of the environment curve segment; if yes, marking the corresponding environment sub-data as a signal influencing factor; and if not, judging the next environmental curve segment.
If the signal curve segment is abnormal, whether the change trend of the signal curve segment is consistent with the change trend of each environmental curve segment (the signal environmental curve intercepted according to the time window) is analyzed, if the signal curve segment is in an ascending trend, the ascending or descending of the environmental curve segment can be understood as the consistent change trend. When the variation trend is consistent, the environment sub-data corresponding to the corresponding environment curve segment is marked as a signal influencing factor.
It should be noted that the corresponding signal influencing factors are the same in each time window, i.e. some environmental sub-data influence a certain time window, but not another time window, so that all environmental curve segments need to be analyzed in each time window.
In a preferred embodiment, after determining the signal influencing factor, calculating the signal influencing weight of the signal influencing factor comprises: marking the mean square error of the first derivative of the corresponding environmental curve segment as HJC; the signal influence weight XYQ corresponding to the signal influence factor is obtained by the formula xyq=β×exp (HJC)/exp (DJC).
The degree of consistent variation trend is mainly considered in the calculation formula of the signal influence weight, and the closer the first derivative mean square error of the two curve segments is, the higher the correlation degree of the variation trend of the two curve segments is, and the larger the corresponding signal influence weight is.
Integrating signal influence factors corresponding to the intelligent terminal and corresponding signal influence weights to generate a signal influence sequence; and the operation and maintenance personnel conduct investigation and treatment on the environment sub-data causing the abnormal wireless network signals of the intelligent terminal according to the signal influence sequence. And the operation and maintenance personnel begin to examine from the signal influence factor with the largest signal influence weight, so that the problem of signal abnormality of the intelligent terminal wireless network is gradually solved.
Referring to fig. 2, a second aspect of the present invention provides an intelligent terminal wireless network signal anomaly monitoring system, configured to implement an intelligent terminal wireless network signal anomaly monitoring method, including a central control module, and a plurality of intelligent terminals communicatively connected to the central control module; the method comprises the steps that test data are sent to a plurality of intelligent terminals through a central control module at regular time, and the intelligent terminals immediately return to the central control module after receiving the test data; the central control module acquires test time after receiving test data returned by the intelligent terminal, and builds a signal test curve based on the test time; judging whether the wireless network signal of the corresponding intelligent terminal is abnormal or not based on the signal test curves, and summarizing signal influence factors according to the signal test curves.
The central control module is mainly controlled by the processor to process data, and is in communication connection with a plurality of intelligent terminals. When a certain intelligent terminal is used as a target, the central control module can only continuously send test data to the intelligent terminal; and when the intelligent terminals in a certain range are targeted, the central control module can send test data to a plurality of intelligent terminals in the range at the same time. The central control module can also communicate with the operation and maintenance personnel in time, and sends the processing result to the operation and maintenance personnel.
An embodiment of a third aspect of the present invention provides an intelligent terminal wireless network signal anomaly monitoring device, including a storage medium and a processor; the storage medium stores operation instructions, and the processor executes the operation instructions to realize an intelligent terminal wireless network signal abnormality monitoring method. It should be noted that, executing the operation instruction by the processor controls an intelligent terminal wireless network signal abnormality monitoring system to operate, and after the system operates, an intelligent terminal wireless network signal abnormality monitoring method is implemented.

The working principle of the invention is as follows:
counting the corresponding duration of the test period and marking the duration as test time; constructing a signal test curve by taking the mark of the test period as an independent variable and the corresponding test time as the dependent variable; and constructing time windows based on the identification of the test period, and analyzing whether the signal test curve is abnormal in each time window.
