That is, in combination with the result of the anomaly analysis of the data reported by the telemechanical equipment (such as whether there is a telemetry mutation, frequent dislocation of telemetry information, etc.), the operation state of the telemechanical equipment is comprehensively evaluated, and an anomaly host and a channel are timely found and alarmed.
In some embodiments, after obtaining the communication message between the remote device and the master station of each station in real time, the method further includes: according to the structure of the station-remote equipment-communication channel, storing communication messages according to a preset time interval; when a channel monitoring instruction is received, reporting data in communication messages in each communication channel are displayed according to the structure of the station-remote equipment-communication channel; when a message monitoring instruction is received, the communication message in each communication channel is displayed according to the structure of the station-remote equipment-communication channel. It should be noted that, the structure of the station-telemechanical equipment-communication channel refers to the hierarchical catalogue of the station-telemechanical equipment-communication channel, namely, the primary catalogue is the station, the secondary catalogue is the telemechanical equipment, the tertiary catalogue is the communication channel, the corresponding secondary catalogue is arranged under each primary catalogue, and each secondary catalogue is provided with the corresponding tertiary catalogue, so that the channel monitoring and the message monitoring are more convenient to check.
In some embodiments, the remote device of each station includes a plurality of telemetry stations, the remote device collects report data from each telemetry station, the communication message adopts a nested map mode, the target information in the communication message is stored in the redis memory database and the java memory, and the target information at least includes a communication channel for transmitting the communication message and the telemetry station corresponding to the report data in the communication message. Referring to fig. 2, fig. 2 is a logic diagram for implementing reporting data verification. In fig. 2, the reported data is an original message, and the target information includes a communication channel for transmitting a communication message, a telemetry measurement point corresponding to the reported data in the communication message, an intermediate variable, and the like.
It can be understood that the data volume of the reported data is large and needs to be analyzed in real time, so that a nested map is constructed, and a redis memory database and a java memory are used for storing important information.
In some embodiments, detecting whether there is an abnormal condition in the reported data in each communication packet between the remote device and the master station (i.e. report data check) includes: acquiring the current measuring point value of each telemetry measuring point in the report data in each communication message between the telemechanical equipment and the master station, wherein the type of the measuring point value can be electric parameters such as voltage, current, frequency, power and the like, or non-electric parameters such as temperature, water level, oil level and the like, and the type of the measuring point value can be different when the telemetry measuring points are different; for each telemetry measuring point, acquiring a current measuring point difference value between a current measuring point value of the telemetry measuring point and a historical measuring point value of the telemetry measuring point; modifying a history measurement point difference value in a redis memory database by adopting the current measurement point difference value, wherein the history measurement point difference value is a nested element in a nested map of target information; when the abnormal condition is abnormal, based on the modified historical measuring point difference value, judging whether the corresponding report data of the telemetry measuring point has abnormal measuring point or not. The difference value of the current measuring point is an intermediate variable, namely the variable quantity between the current measuring point value of the telemetry measuring point and the historical measuring point value of the telemetry measuring point. Based on the modified historical measurement point difference value, judging whether the report data of the corresponding telemetry measurement point has measurement point abnormality or not can comprise the following steps: when the modified historical measurement point difference value is 0, the measurement point value of the corresponding telemetry measurement point is judged not to be refreshed, so that the report data of the corresponding telemetry measurement point is judged to have the measurement point abnormality that the measurement point value is not refreshed, and the verification of the report data is realized. The historical measurement point difference value is modified through the current measurement point difference value, so that the verification of the next reported data can be independent of the historical multiple measurement point values.
It can be understood that by constructing a special intermediate variable, dependency on historical data is reduced, taking an example of judging abnormality (such as that a measurement point is not refreshed, frequency changes, etc.) of reported data within one minute, according to practical situations, a historical time period is generally required to be used as a reference, so that each time of verification needs to combine and calculate the historical data with a current measurement point value at a current moment, repeated calculation can be caused, and therefore, the intermediate variable is created, and the value of the intermediate variable is calculated and modified during each time of verification, so that the use of a memory can be greatly reduced and the verification efficiency of the reported data can be improved when the historical data is not relied on during the next verification of the reported data.
In some embodiments, for a single telemetry site, the reporting data corresponding to the single telemetry site is stored as a file. Detecting whether the report data in each communication message between the remote equipment and the master station has abnormal conditions or not can comprise: reading a file of a single telemetry measurement point; and aiming at the file of the single telemetry measurement point, sequentially detecting whether the reported data corresponding to the single telemetry measurement point has channel consistency check abnormality, measurement point abnormality, communication channel abnormality and station abnormality. All the anomalies can be analyzed once for one file of a single telemetry measurement point through one file of the telemetry measurement point, so that the code coupling degree is reduced, different anomalies are prevented from being analyzed by reading the reported data corresponding to the same telemetry measurement point for multiple times, and the efficiency of anomaly analysis is improved.
It can be understood that when the original message is analyzed, the information of each telemetry measurement point is stored as a file independently and is used for other services in a character string splicing mode, if the analyzed clear text is stored in a unit of a channel file name or directly stored, the calculation when the abnormal situation analysis is performed also needs to be split, and as the content is increased, the json format file is increased, and the efficiency is also lowered. The content stored in the mode provided by the embodiment not only can be convenient for front-end curve display, but also can be used for other businesses to calculate, and can reduce the code coupling degree.
