[0059] 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.

[0060] Reference Figure 1 As shown, a water, electricity, gas and heat meter centralized reading system comprises:

[0061] A carbon copy decomposition module, wherein the carbon copy decomposition module performs data carbon copy when the data of the instrument being carbon copied changes, and decomposes the data carbon copy process into at least one carbon copy basic element;

[0062] a cc determination module, wherein the cc determination module determines the cc type of the cc basic element, the cc type of the cc basic element including water meter data, electric energy meter data, gas meter data and heat energy meter data, wherein the meter is a water meter, an electric energy meter, a gas meter and a heat energy meter;

[0063] A model building module, wherein the model building module builds a key parameter identification model;

[0064] A key parameter identification module, wherein the key parameter identification module identifies and obtains the key parameters of the basic element and the standard characteristic values ​​of the key parameters according to the key parameter identification model;

[0065] An error generation module, wherein the error generation module obtains the allowable error of the key parameters of the basic element of the copy, and obtains a preset value of the allowable deviation degree;

[0066] A monitoring module monitors the key parameters of the CC basic element, obtains the actual monitoring values ​​of the key parameters of the CC basic element, calculates the degree of deviation between the actual monitoring values ​​and the corresponding standard characteristic values, and determines whether the degree of deviation is greater than a preset value. If so, an early warning is issued; if not, the real-time CC data of the CC basic element is used.

[0067] In this scheme, whether the data is abnormal is judged according to the degree of data fluctuation, so that the abnormal data can be identified to a certain extent, thereby identifying the corresponding instrument problem, but due to the various possibilities of abnormalities, it is impossible to identify all abnormalities, and only part of the data related to data fluctuations can be identified. As for the attribution of data, it is distinguished according to the speed at which the data of different types of instruments change, because different types of instruments measure different objects and their consumption speeds are also different. Therefore, the data can be identified according to the different speeds and then classified.

[0068] Reference Figure 2 As shown, judging the type of the copy basic element includes the following steps:

[0069] Based on historical data, obtain the data change range per unit time when the water meter data changes, as the water meter reference range;

[0070] Obtain the data change range of the electric energy meter data per unit time when the data changes, as the reference range of the electric energy meter;

[0071] Obtain the data change range of the gas meter data per unit time when the data changes, as the reference range of the gas meter;

[0072] Obtain the data change range of the heat energy meter data per unit time when the data changes, as the heat energy meter reference range;

[0073] Calculate the value of the data copied by the basic element of copy in unit time as the copy judgment value;

[0074] When the CC judgment value belongs to the water meter reference range, the CC type of the CC basic element is water meter data;

[0075] When the CC judgment value belongs to the reference range of the electric energy meter, the CC type of the CC basic element is the electric energy meter data;

[0076] When the CC judgment value belongs to the gas meter reference range, the CC type of the CC basic element is gas meter data;

[0077] When the CC judgment value belongs to the heat meter reference range, the CC type of the CC basic element is the heat meter data.

[0078] The purpose of identifying the CC type of the CC basic element is to determine the ownership of the CC data and then obtain the source of the CC data.

[0079] Reference Figure 3 As shown, establishing the key parameter identification model includes the following steps:

[0080] Generate key parameters of water meter data, key parameters of electric energy meter data, key parameters of gas meter data and key parameters of heat meter data respectively;

[0081] The key parameters of water meter data are generated by: obtaining water meter copy data in the process of water meter data copy, obtaining the water meter copy data at intervals of preset time, averaging the absolute values ​​of the differences between adjacent water meter copy data, and obtaining the key parameters of water meter data;

[0082] The key parameters of the electric energy meter data are generated by: acquiring the electric energy meter copy data in the process of copying the electric energy meter data, acquiring the electric energy meter copy data at intervals according to a preset time, taking an average of the absolute values ​​of the differences between the adjacent electric energy meter copy data, and obtaining the key parameters of the electric energy meter data;

[0083] The key parameters of the gas meter data are generated by: acquiring the gas meter copy data in the process of gas meter data copy, acquiring the gas meter copy data at intervals of a preset time, averaging the absolute values ​​of the differences between the adjacent gas meter copy data, and obtaining the key parameters of the gas meter data;

[0084] The key parameters of heat energy meter data are generated by: obtaining heat energy meter copy data in the process of heat energy meter data copy, obtaining the heat energy meter copy data at intervals according to a preset time, averaging the absolute values ​​of the differences between adjacent heat energy meter copy data, and obtaining the key parameters of heat energy meter data.

[0085] When the data is copied, since the data comes from different instruments, the parameters after copying are also different. Therefore, it is necessary to determine the indicators used to judge whether the data is abnormal in different situations. To this end, the key parameters of data copying and the standard characteristic values ​​corresponding to the key parameters in different situations are obtained. The key parameters can be used to judge whether the data copying is abnormal.

[0086] Reference Figure 4 As shown, identifying the key parameters of the carbon copy basic element and the standard characteristic values ​​of the key parameters includes the following steps:

[0087] Under the condition that the instrument operates normally, the judgment result of the CC type of the CC basic element is obtained;

[0088] If the copy type is water meter data, then taking an average of at least one reference value of the key parameter of the copied water meter data to obtain a standard value of the key parameter of the water meter data;

[0089] The key parameters of water meter data are used as the key parameters of the basic element of the copy, and the standard values ​​of the key parameters of water meter data are used as the standard characteristic values ​​of the key parameters;

[0090] If the copy type is electric energy meter data, then taking an average of at least one reference value of a key parameter of the electric energy meter data after the copy is sent, to obtain a standard value of the key parameter of the electric energy meter data;

[0091] The key parameters of the electric energy meter data are used as the key parameters of the basic element of the copy, and the standard values ​​of the key parameters of the electric energy meter data are used as the standard characteristic values ​​of the key parameters;

[0092] If the copy type is gas meter data, then taking an average of at least one reference value of the key parameter of the copied gas meter data to obtain a standard value of the key parameter of the gas meter data;

[0093] The key parameters of the gas meter data are used as the key parameters of the CC basic element, and the standard values ​​of the key parameters of the gas meter data are used as the standard characteristic values ​​of the key parameters;

[0094] If the copy type is heat meter data, then average at least one reference value of the key parameter of the heat meter data after copying to obtain the standard value of the key parameter of the heat meter data;

[0095] The key parameters of the heat energy meter data are used as the key parameters of the basic elements of the copy, and the standard values ​​of the key parameters of the heat energy meter data are used as the standard characteristic values ​​of the key parameters.

[0096] The standard characteristic value of the key parameter is used to judge the degree of deviation. It uses the mean of the standard values ​​of the key parameters of the same type of data as the basis for judgment. It mainly examines the fluctuation of the data. Since the time interval is the preset time, when the preset time is small enough, taking the water meter as an example, the adjustment of the water flow size only accounts for a very small part of the use, and since the preset time is small enough, even during the adjustment process, it can be approximately considered that the water flow size is unchanged. Therefore, the key parameters reflect the volatility of the data. Because when the water flow size remains unchanged and there is no abnormality in the instrument, the fluctuation of the measured value will be limited to a fixed range. When it exceeds this range, it means that the data is abnormal, and then the corresponding instrument is judged to be abnormal. Therefore, it can be guaranteed that the data used are relatively accurate.

[0097] Reference Figure 5 As shown, obtaining the allowable error of the key parameters of the basic element of the copy and send and obtaining the preset value of the allowable deviation degree includes the following steps:

[0098] Based on historical data, under the condition that the meters are operating normally, the fluctuation ranges of the key parameters of the water meter data, the key parameters of the electric energy meter data, the key parameters of the gas meter data and the key parameters of the heat meter data are obtained respectively;

[0099] When the key parameter of the water meter data is the key parameter of the CC basic element, the length of the fluctuation range of the key parameter of the water meter data is used as the allowable error of the key parameter of the CC basic element;

[0100] When the key parameter of the electric energy meter data is the key parameter of the copy basic element, the length of the fluctuation range of the key parameter of the electric energy meter data is used as the allowable error of the key parameter of the copy basic element;

[0101] When the key parameter of the gas meter data is the key parameter of the copy basic element, the length of the fluctuation range of the key parameter of the gas meter data is used as the allowable error of the key parameter of the copy basic element;

[0102] When the key parameter of the heat meter data is the key parameter of the copy basic element, the length of the fluctuation range of the key parameter of the heat meter data is used as the allowable error of the key parameter of the copy basic element;

[0103] The allowable error is divided by the maximum value of the key parameter corresponding to the carbon copy basic element to obtain a preset value.

[0104] For different CC data, the allowable error will be different, so there will be corresponding different preset values. It is necessary to calculate each type of CC data one by one to obtain the corresponding preset value, so as to judge whether the data CC is accurate during subsequent monitoring.

[0105] Reference Figure 6 As shown, obtaining the actual monitoring values ​​of the key parameters of the CC basic element includes the following steps:

[0106] Acquire real-time CC data of the CC basic element, and acquire at least one real-time interval data in the real-time CC data according to a preset time as an interval;

[0107] The absolute values ​​of the differences between the adjacent real-time interval data are averaged to obtain the actual monitoring values ​​of the key parameters of the CC basic element.

[0108] Calculating the degree of deviation between the actual monitoring value and the corresponding standard characteristic value includes the following steps:

[0109] The actual monitoring value is subtracted from the corresponding standard characteristic value and the absolute value is taken. The absolute value is divided by the corresponding standard characteristic value to obtain the degree of deviation.

[0110] The degree of deviation is used to judge the degree of passability of data copy. If the degree of deviation is greater than the preset value, it means that the accuracy of the copy data has deviated during the copy process. Therefore, it is necessary to stop the copy and check to eliminate the copy error.

[0111] The working process of the above-mentioned water, electricity, gas and heat meter centralized reading system is as follows:

[0112] Step 1: The CC decomposition module decomposes the data CC process into at least one CC basic element, and the CC judgment module judges the CC type of the CC basic element, and the CC types of the CC basic element include water meter data, electric energy meter data, gas meter data and heat energy meter data;

[0113] Step 2: The model building module builds a key parameter identification model;

[0114] Step 3: The key parameter identification module identifies the key parameters of the basic element and the standard characteristic values ​​of the key parameters according to the key parameter identification model;

[0115] Step 4: The error generation module obtains the allowable error of the key parameters of the basic element of the copy, and obtains the preset value of the allowable deviation degree;

[0116] Step 5: The monitoring module monitors the key parameters of the CC basic element, obtains the actual monitoring value of the key parameters of the CC basic element, calculates the degree of deviation between the actual monitoring value and the corresponding standard characteristic value, and determines whether the degree of deviation is greater than the preset value. If so, an early warning is issued, otherwise, no action is taken.

[0117] Furthermore, the present solution also proposes a storage medium on which a computer-readable program is stored. When the computer-readable program is called, the above-mentioned water, electricity, gas and heat four-meter centralized reading system is executed.

[0118] It is understandable that the storage medium may be a magnetic medium, such as a floppy disk, a hard disk, or a magnetic tape; an optical medium, such as a DVD; or a semiconductor medium, such as a solid state drive (SSD).

[0119] In summary, the advantages of the present invention are: by setting a copy judgment module, a model building module, a key parameter identification module and a monitoring module, in the data copy process, the data copy process is decomposed into copy basic elements, and in each copy basic element, the key parameters during data copy can be independently identified, and the standard characteristic values ​​of the key parameters can be obtained. The data is monitored for the key parameters, and then the copy quality can be monitored in real time during the data copy process, and then the data can be automatically identified to prevent the data from being matched to the wrong instrument and causing confusion in the data copy. At the same time, the accuracy of the data can be controlled to a certain extent, thereby ensuring the accuracy of the data.
