Abstract

The present invention discloses a method and system for processing massive gas filling data at a gas filling station, which relates to the field of data processing technology, including extracting and processing the database of the gas filling station to obtain the historical data of the gas filling station; preprocessing the data based on the historical data of the gas filling station to obtain several groups of gas filling order information.

[0074] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0075] Please refer to Figure 1-Figure 5 As shown, a method for processing massive gas filling data at a gas filling station includes:

[0076] Extract and process the database of the gas station to obtain the historical data of the gas station;

[0077] Preprocess the data based on the historical data of the gas station to obtain several groups of gas order information;

[0078] Search the database based on several groups of gas filling order information to obtain the gas filling rate information corresponding to the order;

[0079] Draw a curve based on the gas filling rate information corresponding to the order, and obtain several groups of order gas filling rate curves;

[0080] Data is screened based on several groups of gas filling order information to obtain several groups of user gas filling times, and the several groups of user gas filling times correspond to several groups of order gas filling rate curves one by one;

[0082] Extract and process the database of gas filling stations to obtain the average gas filling rate of the gas filling stations;

[0083] A judgment process is performed based on the gas filling rate offset to determine the status of the gas filling station.

[0084] It can be understood by those skilled in the art that the gas filling orders of all users on the same day are first obtained, and the gas filling rates of all users are extracted by means of data retrieval. Then, the gas filling time of the users is obtained by means of data screening, and a gas filling rate curve is drawn for all users. The gas filling time of each user is in a one-to-one correspondence with the gas filling rate curve of their respective orders. Then, a proximity analysis is performed on the gas filling rate curves of the orders in adjacent time periods. The proximity refers to the overlap relationship. The adjacent time periods refer to the comparison of the gas filling rates of two adjacent users before and after the gas filling process on the same day. Because only when the gas filling of two adjacent users before and after one day is taken, the data is targeted. If the number of days between the two users is large, the gas station may have been gassed, and the data will not be logical. After the comparison, the gas filling rate offset is obtained, and the gas filling rate offset is judged to obtain the status of the gas station.

[0085] Preprocessing the data based on the historical data of the gas station to obtain several groups of gas order information specifically includes the following steps:

[0086] Perform outlier deletion processing on historical data to obtain first processed data;

[0087] Perform missing value filling processing on the first processed data to obtain second processed data;

[0088] The specific calculation formula for filling missing values ​​is: ;

[0089] In the formula, is the filling data; i is the number of filling data; are different types of historical data; n is the number of different types of historical data;

[0090] Classification is performed based on the second processed data to obtain several groups of gas filling order information.

[0091] Searching the database based on several groups of gas filling order information to obtain the gas filling rate information corresponding to the order specifically includes the following steps:

[0092] Searching the database based on several groups of gas filling order information to obtain gas filling volume information and gas filling completion time information;

[0093] Calculate based on the gas filling volume information and the gas filling completion time information to obtain the gas filling rate information;

[0094] Among them, the specific calculation formula for obtaining the gas filling rate is: ,

[0095] In the formula, is the gas filling rate, T is the gas filling completion time, and S is the gas filling volume.

[0096] Drawing a curve based on the gas filling rate information corresponding to the order, and obtaining a number of groups of order gas filling rate curves specifically include the following steps:

[0097] A rectangular coordinate system is established with the filling completion time information as the X-axis and the filling volume information as the Y-axis;

[0098] Based on the gas filling rate information corresponding to the several groups of orders, curves are drawn in a rectangular coordinate system to obtain the gas filling rate curves of the several groups of orders.

[0099] The steps of performing a proximity analysis on the order gas filling rate curves in adjacent time periods and obtaining the gas filling rate offset are as follows:

[0100] Performing time analysis on the gas filling rate curve based on the gas filling order information to determine the gas filling rate curve information for adjacent time periods;

[0101] The gas filling rate offset is obtained by performing calculation based on the gas filling rate curve information of adjacent time periods.

[0102] The calculation and processing based on the gas filling rate curve information of adjacent time periods to obtain the gas filling rate offset specifically includes the following steps:

[0103] Extract time features from the gas filling rate curves in adjacent time periods to determine the completion time of two groups of gas filling;

[0104] Calculate and process the two groups of gas filling completion time to obtain the minimum gas filling completion time;

[0105] Among them, the specific calculation formula for the minimum gas filling completion time is: ;

[0106] in, The gas filling completion time for two groups respectively;

[0107] The minimum gas filling completion time is set as the reference time, and the curve of another group of gas filling completion time is removed by the reference time to obtain the gas filling rate curve;

[0108] A comparison process is performed based on the processed gas filling rate curve and the gas filling rate curve corresponding to the reference time to obtain the gas filling rate offset.

[0109] It can be understood by those skilled in the art that, because the order information is different, the filling time and volume are also different, and therefore it is necessary to use the shortest time as a reference to eliminate the long-time curve, so that the short-time curve and the long-time curve are judged within the same time to obtain the filling rate offset between the two; and if an order data is too long and is eliminated, the eliminated data pattern is the same as the non-eliminated data pattern.

[0110] The judgment process based on the gas filling rate offset is used to determine the state of the gas filling station, which specifically includes the following steps:

[0111] Making a judgment based on the gas filling rate offset and a set first threshold;

[0112] If the gas filling rate offset is greater than the set first threshold, the first gas filling rate abnormal point is output;

[0113] If the gas filling rate offset is equal to the set first threshold, the output gas filling is normal;

[0114] If the gas filling rate offset is less than the set first threshold, a second judgment is made on the gas filling rate offset;

[0115] Analyze the first abnormal point of gas filling rate to determine the status of the gas filling station.

[0116] The secondary judgment of the gas filling rate offset specifically includes the following steps:

[0117] Making a judgment based on the gas filling rate offset and a set second threshold;

[0118] If the gas filling rate offset is less than the set second threshold, the second gas filling rate abnormal point is output;

[0119] If the gas filling rate offset is greater than or equal to the set second threshold, the output gas filling is normal;

[0120] Obtaining time data corresponding to the second gas filling rate abnormal point;

[0121] Performing data extraction processing on the database based on the time data corresponding to the abnormal point of the second gas filling rate, and determining the second gas storage volume of the gas filling station;

[0122] Making a judgment based on a second gas storage volume of the gas filling station and a set third threshold;

[0123] If the second gas storage volume of the gas filling station is less than or equal to the set third threshold, the output gas filling station has insufficient gas storage and cannot reach the average gas filling rate, and the gas filling station is in normal state;

[0124] If the gas storage volume of the gas filling station is greater than the set third threshold, the output gas filling station pipeline is abnormal.

[0125] Analyzing the first abnormal point of the gas filling rate and determining the state of the gas filling station specifically includes the following steps:

[0126] Performing data extraction processing on the database based on the time data corresponding to the first gas filling rate abnormal point to determine the first gas storage volume of the gas filling station;

[0127] Making a judgment based on a first gas storage volume of the gas filling station and a set fourth threshold;

[0128] If the first gas storage volume of the gas filling station is less than or equal to the set fourth threshold value, the output gas filling station has insufficient gas storage and cannot reach the average gas filling rate, and the gas filling station is in a normal state;

[0129] If the first gas storage volume of the gas filling station is greater than the set fourth threshold, the pipeline of the gas filling station is abnormal.

[0130] It can be understood by those skilled in the art that when the gas filling rate offset is greater than the set first threshold, there are two abnormal situations, one is that the rate slows down, and the other is that the rate is too large. The slow rate is related to insufficient gas at the gas station and blockage in the gas pipeline. If the gas volume is sufficient and the gas rate increases, it means that the gas station pipeline is damaged. Therefore, the present invention introduces the second threshold and the third threshold for comparative analysis to determine the status of the gas station, which is convenient for the staff to refuel or repair it and ensure that subsequent users can refuel normally.

[0131] A system for processing massive gas filling data at a gas filling station, comprising:

[0132] An extraction module is used to extract the database of the gas filling station, obtain the historical data of the gas filling station and obtain the average gas filling rate of the gas filling station;

[0133] The data preprocessing module is used to preprocess the historical data of the gas station and obtain several groups of gas filling order information;

[0134] A search module is used to search a database for several groups of gas filling order information to obtain gas filling rate information corresponding to the order;

[0135] A curve drawing module is used to draw a curve for the gas filling rate information corresponding to the order, and obtain several groups of order gas filling rate curves;

[0136] The data screening module is used to screen the gas filling order information and obtain the gas filling time of several groups of users;

[0137] The proximity analysis module is used to perform proximity analysis on the order gas filling rate curves in adjacent time periods to obtain the gas filling rate offset;

[0138] The judgment module is used to judge the gas filling rate offset and determine the state of the gas filling station.

[0139] To summarize, first obtain the gas filling orders of all users on the same day, extract the gas filling rates of all users through data retrieval, and then obtain the gas filling time of the users through data screening, draw a curve for the gas filling rate of all users, and the gas filling time of each user is in a one-to-one correspondence with the gas filling rate curve of their respective orders; then perform a proximity analysis on the gas filling rate curves of orders in adjacent time periods, and the proximity refers to the overlap relationship. Adjacent time periods refer to the comparison of the gas filling rates of two adjacent users before and after the gas filling process on the same day. Because only when the gas filling of two adjacent users on the same day is taken before and after, the data is targeted. If the number of days between the data is large, the gas station may have been refueled, and the data will not be logical. After comparison, the gas filling rate offset is obtained, and the gas filling rate offset is judged with the first threshold value to output the first abnormal point. There are two types of abnormal points, one is that the rate slows down, and the other is that the rate is too large. The slow rate is related to the insufficient gas volume at the gas station and the blockage of the gas pipeline; if the gas volume is sufficient and the gas rate increases, it means that the gas station pipeline is damaged. Therefore, the present invention introduces the second threshold and the third threshold value, and compares and analyzes them to determine the status of the gas station, which is convenient for the staff to refuel or repair it, and ensure that subsequent users refuel normally.
