Along with the continuous rising of the status of natural gas as an environment-friendly energy source, the accurate, fair and fair metering work of natural gas is an important technical work for scientifically managing natural gas, and the natural gas is related to multiple benefits. Meanwhile, the natural gas is used as fuel, the actual value of the natural gas is the calorific value of the natural gas rather than the volume, and the foreign natural gas metering mode generally adopts an energy metering method, so that unnecessary disputes are inevitably generated in the process of natural gas trade handover with other countries, and the research of natural gas energy metering equipment is very significant.
When data analysis is performed on the natural gas energy metering, repeated data are often interfered in the acquired energy metering result, if the repeated data are added into statistics, the final analysis result can be greatly influenced, so that the analysis and judgment of the natural gas energy metering data are influenced, and the problem to be solved in the natural gas energy metering field is solved urgently by how to avoid the influence of the repeated data on the analysis of the natural gas energy metering data.

At present, when natural gas energy metering is performed, the natural gas energy metering is mainly based on a natural gas energy metering result, and the energy metering module can effectively obtain the natural gas energy metering result after obtaining the physical data of the natural gas and the calculation result of the natural gas unit heating value, and in general, the natural gas energy metering result is realized by matching the standard flow of a set time period and the natural gas unit heating value of a corresponding time period, so that the natural gas energy metering obtained in different time periods is different, and when communication data containing the natural gas energy metering is sent outwards, each communication data should represent different natural gas energy metering results, but because the communication data are not set to be differentiated, a large amount of extra effort is required by a worker to discriminate the validity of the communication data after receiving the communication data, and especially in the point of eliminating redundant communication data, the follow-up work is extremely influenced, and even the follow-up work fails.
The built-in gateway is connected to the energy calculation module, the built-in gateway can perform communication pretreatment work so as to facilitate normal transmission of communication data, meanwhile, the communication data processing module can also effectively discriminate the communication data transmitted by the energy calculation module, different communication data are distinguished in the communication data processing module in a mode of numbering the communication data and adding a timestamp to the communication data after being compiled, and when the communication data processing module transmits the communication data to a subsequent module, staff can effectively distinguish each communication data and also conveniently sort and store the communication data; according to the invention, the communication data is provided with the capability of being directly identified and distinguished by numbering and adding the time stamp into the communication data processing module, so that when a large amount of communication data is received by a worker, the communication data can be rapidly and effectively processed, at least one identical communication data with the number and the time stamp can be used as the problem data to be identified for processing, thus not only can redundant communication data be avoided to increase the workload of the worker, but also the problem data can be effectively identified, and the worker can more carefully treat the problem data when facing the problem data, and the influence of the problem data on the subsequent work can be avoided.
Furthermore, the built-in gateway also comprises a data storage module, and the communication data is transmitted to the data storage module for backup after being numbered and added with a time stamp;
the energy calculation module sends the natural gas energy calculation result to the built-in gateway with identity marks, the communication data processing module sends a query instruction to the data storage module after receiving the communication data sent by the energy calculation module, the identity marks of the natural gas energy calculation result in the communication data are compared with the identity marks of the communication data in the data storage module, if the identity marks are the same and the time stamps of the communication data are the same, one piece of communication data is abandoned, and if the identity marks are the same but the time stamps of the communication data are different, the two pieces of communication data are marked in error.
In the prior art, communication data is directly sent to a user side after being processed and is not stored locally, so that maintenance after problems are unfavorable, backup cannot be effectively found after the user side loses data, and the risk of a user is greatly increased. In the invention, identity marks are set on the natural gas energy calculation result in the energy calculation module, so the energy calculation result is provided with the identity marks before being converted into communication data, which avoids repeated numbering and marking different time stamps on the same communication data when the numbering and the adding of the time stamps are carried out in the communication data processing module, thus the same communication data can be processed by staff as different communication data, which is unfavorable for the development of subsequent work, therefore, the invention is particularly set, if the identity marks are identical and the time stamps of the communication data are identical, one of the communication data is abandoned, if the identity marks are identical but the time stamps of the communication data are different, the error marks are carried out on the two communication data, after the processing, the identity marks, the numbering and the time stamps are identical, only one piece of communication data is left, redundant communication data is effectively removed, and errors of the following situations can also occur in the data processing process, the first situation is that the communication data of the same identity marks are processed differently, the second situation is different numbering and the time stamps are different, the error is carried out on the communication data of the two kinds of the communication data, the invention can be distinguished, the error data can be prevented from being influenced by the personnel, the error is prevented from being influenced by the fact that the two pieces of the communication data are processed, and the error data are processed, the error is different in the time stamps are different, and the data are compared with the data are input by the data after the data, the energy calculation results after the identity marking are added with different numbers and time stamps, so that the situation that the same energy calculation results are marked with different numbers and time stamps and treated as different energy calculation results due to transmission errors or channel blockage is avoided.
