Description

Technical Field

[0001] The present invention relates to the field of natural gas energy metering, and in particular to a synchronous energy metering device and an Internet of Things system embedded with an information security module. Background Art

[0002] As a high-quality, efficient, clean energy and important chemical raw material, natural gas has been widely valued and given priority in all countries around the world, accounting for 35% of the energy structure. With the increasing status of natural gas as an environmentally friendly energy source, accurate, fair and impartial measurement of natural gas is an important technical work for scientific management of natural gas, which is related to the interests of many parties. At the same time, as a fuel, the actual value of natural gas should be its calorific value rather than its volume. The natural gas measurement method abroad generally adopts the energy measurement method, so it is inevitable that unnecessary disputes will arise during the natural gas trade handover process with other countries. Therefore, it is of great significance to carry out research on natural gas energy metering equipment.

[0003] At present, when natural gas energy metering is performed, the data will be sent to the management platform for unified management after calculation. However, due to the single source of data, the accuracy of the data cannot be verified. Since the amount of data in natural gas energy metering is particularly large and the conditions for local calculations are limited, the calculation pressure of energy calculation is relatively large when the amount of data is too large. Therefore, in the long-term data calculation and collation, it cannot be guaranteed that the metering results will always remain accurate. Therefore, how to reduce the burden of local energy calculation and verify the energy calculation results has become an urgent problem to be solved in the field of natural gas energy metering. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art due to the huge amount of data, the huge amount of calculation, and the fact that energy calculation results can only be obtained through a single channel, resulting in the inability to avoid calculation errors caused by excessive calculation burden. A synchronous energy metering device and an Internet of Things system embedded with an information security module are provided. By preprocessing the collected natural gas physical data and synchronously sending the energy calculation results and preprocessing information, the management platform can not only directly obtain the energy calculation results, but also realize remote energy metering and accounting through the obtained preprocessing information, thereby realizing the synchronous metering of natural gas energy by the metering device and the management platform, facilitating mutual verification and analysis of the metering results, and improving the metering accuracy.

[0005] The purpose of the present invention is mainly achieved through the following technical solutions:

[0006] A synchronous energy metering device embedded with an information security module comprises a natural gas data acquisition system, a calorific value analysis and processing system, a data preprocessing module and an energy calculation module, wherein the natural gas data acquisition system and the calorific value analysis and processing system are both connected to the data preprocessing module, and the data preprocessing module is connected to the energy calculation module, wherein:

[0007] The natural gas data acquisition system is used to collect the physical data of natural gas and send it to the data preprocessing module;

[0008] The calorific value analysis and processing system is used to calculate the unit calorific value of natural gas and send the calculation results to the data preprocessing module;

[0009] A data preprocessing module is used to receive natural gas physical data and natural gas unit calorific value calculation results, classify and store the data to form preprocessing information, and send the preprocessing information to the energy calculation module;

[0010] An energy calculation module, used for receiving preprocessing information and performing natural gas energy calculation;

[0011] The energy calculation module is also connected to an information security management module, the information security management module is bidirectionally electrically connected to the energy calculation module, the information security management module is bidirectionally electrically connected to the data preprocessing module, and the information security management module is used to encrypt and decrypt the energy calculation results and preprocessing information;

[0012] The information security management module is connected to a communication module, and the communication module is used for sending communication data, and the communication data is the energy calculation result and pre-processing information after encryption and decryption.

[0013] At present, due to the extremely large amount of data in natural gas energy metering and the limited conditions for local calculations, the calculation pressure of capacity calculation is relatively large when the amount of data is too large. Therefore, it cannot be guaranteed that the metering results will remain accurate in long-term data calculation and sorting. Therefore, in the present invention, the energy calculation results of the energy calculation module and the preprocessing information of the data preprocessing module are both sent to the communication module, and the energy calculation results and the preprocessing information are sent to the management platform through the communication module. The management platform can calculate the preprocessing information to achieve the purpose of verifying the energy calculation results. Since the management platform can also calculate the preprocessing information, the calculation results can be pushed back to the energy calculation module to assist the calculation, so the calculation pressure of the energy calculation module is reduced.

[0014] When the energy calculation results and preprocessing information are sent to the communication module synchronously, since it is necessary to distinguish the two data streams and to protect data security, an information security management module is set before the communication module receives the preprocessing information and the energy calculation results. The information security management module can perform identity authentication of information interaction objects, encryption and decryption of interaction data, and verification of the integrity and validity of interaction data, so that information security can be effectively guaranteed, and the preprocessing information and energy calculation results can be effectively distinguished, which is beneficial for the management platform to organize and calculate data; the present invention preprocesses the collected natural gas physical data and synchronously sends the energy calculation results and preprocessing information, so that the staff can obtain the preprocessing information and the energy calculation results at the same time, which is convenient for the staff to mutually verify and analyze the preprocessing information and the energy calculation results.

[0015] Furthermore, the communication module includes a streaming unit, and the streaming unit is used to perform the following steps:

[0016] Acquire communication data in real time, and acquire a timestamp corresponding to the time when the communication data is received in real time;

[0017] The timestamp is combined with the corresponding communication data to form data to be sent;

[0018] The data to be sent are pushed in sequence according to the order of timestamps, and the time interval between each data to be sent is consistent with the time interval of the timestamps.

[0019] At present, when transmitting communication data for natural gas energy metering, due to the huge amount of data, the data receiving and sending channels generally used are difficult to send and receive communication data in a timely and effective manner, which will cause congestion of communication data. Under the premise of communication data congestion, communication data packet loss is likely to occur, and the communication data packet loss is generally due to the communication data occupying the sending channel in no particular order, resulting in the communication data being lost when it is sent, thereby causing data packet loss. The present invention queues the communication data in a manner of storing timestamps together with the communication data, and sends the communication data in sequence according to the order of timestamps, thereby effectively organizing the communication data sending method, and avoiding blockage of the data sending channel of the communication module, and also enabling the management platform to obtain more complete communication data.

[0020] Furthermore, a buffer unit is provided in the communication module, and the buffer unit is used to maintain a data queue, and the data queue is used to store a section of data to be sent. After the data queue is full, the communication module sends the data to be sent in the order of timestamps.

[0021] Simply sorting the communication data can alleviate the congestion of the communication module data to a certain extent, but when a large amount of communication data flows in within a short period of time, it will still cause data transmission congestion. The present invention adopts the method of constructing a buffer unit to effectively establish a data queue. Through the integration of the data queue, the communication data can be effectively sent in the order of timestamps. Due to the existence of the data queue, the situation where a large amount of communication data flows in at the same time is avoided, thereby reducing the burden of sending communication data. The data queue can make the sending of communication data more orderly.

[0022] Furthermore, when the data queue of the buffer unit is full, new data to be sent enters the data queue and is placed at the end of the queue, and the data to be sent at the head of the queue is sent.

[0023] In the present invention, by buffering the data queue in the buffer unit, the communication data can enter the data queue for sorting before sending. In addition to making the sending of communication data more orderly, the data queue can also effectively avoid the loss of intermediate data. Since the communication data in the present invention is arranged according to timestamps, and the timestamps are independently obtained when the communication data is obtained, if the timestamp is missing in the data queue, it proves that data loss exists here, thereby avoiding the staff ignoring the data packet loss phenomenon in the data queue.

[0024] Furthermore, the interval between the real timestamps of two adjacent communication data is taken as the real time difference, and after pushing one piece of data to be sent, the next piece of data to be sent is sent after waiting for the real time difference.

[0025] In order to avoid congestion in data transmission when communication data is sent, the present invention waits for the real time difference after pushing a piece of data to be sent before sending the next piece of data to be sent, thereby making the sending of communication data and the reception of communication data by the management platform smoother, effectively avoiding congestion when sending communication data.

[0026] Furthermore, taking the timestamp of sending the first data to be sent as the starting point, the time of subsequently sending the data to be sent is calculated according to the time difference between the timestamp of the data to be sent and the starting point.

[0027] The present invention does not use the interval time between two pieces of data to be sent as the standard as the time interval for data transmission, which effectively avoids the measurement error of the interval time. Instead, by taking the timestamp of sending the first piece of data to be sent as the starting point, the time for subsequent sending of the data to be sent is calculated according to the time difference between the timestamp of the data to be sent and the starting point, thereby eliminating the time error between each communication data and the previous communication data, thereby obtaining smoother data transmission and more effectively avoiding congestion and packet loss in the data channel.

[0028] Furthermore, the natural gas data acquisition system includes a flow sensor, a pressure sensor and a temperature sensor, and the flow sensor, pressure sensor and temperature sensor are all connected to the data preprocessing module. The data preprocessing module can calculate the operating flow rate of natural gas through the natural gas physical data collected by the flow sensor, pressure sensor and temperature sensor, and realize the conversion of the operating flow rate to the standard flow rate.

[0029] Furthermore, the communication module is also connected to a combustible gas detection alarm module, and the combustible gas detection alarm module is used to detect the leakage status of pipeline natural gas and output alarm information.

[0030] Furthermore, the calorific value analysis and processing system includes a calorific value analysis and processing module, the input end of which is connected to a sample gas processing system and a standard gas processing system, wherein:

[0031] The input end of the sample gas processing system is connected to a sample gas controller. The sample gas processing system is used to remove impurities from the collected natural gas. The calorific value analysis and processing module calculates the unit calorific value of the natural gas after the impurities are removed, and transmits the calculation result to the energy calculation module.

[0032] The input end of the standard gas processing system is connected to the standard gas collection port. The standard gas processing system is used to remove impurities from the collected standard gas. The calorific value analysis and processing module calculates the calorific value of the standard gas after impurities are removed, and compares the calculation result with the standard value of the calorific value of the standard gas to achieve calibration of the calorific value analysis and processing module.

[0033] A synchronous energy metering IoT system embedded with an information security module includes a user platform, a service platform, a management platform, a sensor network platform, and a perception control platform that interact in sequence;

[0034] The perception control platform is the natural gas energy metering device, and the perception control platform transmits the acquired perception information to the management platform through the sensor network platform;

[0035] The management platform includes an energy metering management system, which performs comprehensive analysis and processing on the received perception information, transmits user demand information to the user platform through the service platform, and issues control instructions to the perception control platform through the sensor network platform.

[0036] In summary, the present invention has the following beneficial effects compared with the prior art:

[0037] (1) The present invention preprocesses the collected natural gas physical data and synchronously sends the energy calculation results and preprocessing information, so that the management platform can not only directly obtain the energy calculation results, but also realize remote energy metering and accounting through the obtained preprocessing information, realize the synchronous metering of natural gas energy by the metering device and the management platform, facilitate the mutual verification and analysis of the metering results, and improve the metering accuracy.

[0038] (2) The present invention queues the communication data by storing the timestamp together with the communication data, and sends the communication data in sequence according to the order of the timestamps, thereby effectively organizing the communication data sending method and avoiding the blockage of the data sending channel of the communication module, and also enabling the management platform to obtain more complete communication data.

[0039] (3) The present invention does not use the interval time between two pieces of data to be sent as the standard as the time interval for data transmission, which effectively avoids the measurement error of the interval time. Instead, the time stamp of sending the first piece of data to be sent is used as the starting point, and the time of subsequent sending of the data to be sent is calculated according to the time difference between the timestamp of the data to be sent and the starting point. In this way, the time error between each communication data and the previous communication data is eliminated, thereby achieving smoother data transmission and more effectively avoiding data channel congestion and packet loss.

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0045] Example:

[0046] like Figure 1-2 As shown, a synchronous energy metering device embedded with an information security module includes a natural gas data acquisition system, a calorific value analysis and processing system, a data preprocessing module and an energy calculation module. The natural gas data acquisition system and the calorific value analysis and processing system are both connected to the data preprocessing module, and the data preprocessing module is connected to the energy calculation module, wherein:

[0047] The natural gas data acquisition system is used to collect the physical data of natural gas and send it to the data preprocessing module;

[0048] The calorific value analysis and processing system is used to calculate the unit calorific value of natural gas and send the calculation results to the data preprocessing module;

[0049] A data preprocessing module is used to receive natural gas physical data and natural gas unit calorific value calculation results, classify and store the data to form preprocessing information, and send the preprocessing information to the energy calculation module;

[0050] An energy calculation module, used for receiving preprocessing information and performing natural gas energy calculation;

[0051] The energy calculation module is also connected to an information security management module, the information security management module is bidirectionally electrically connected to the energy calculation module, the information security management module is bidirectionally electrically connected to the data preprocessing module, and the information security management module is used to encrypt and decrypt the energy calculation results and preprocessing information;

[0052] The information security management module is connected to a communication module, and the communication module is used for sending communication data, and the communication data is the energy calculation result and pre-processing information after encryption and decryption.

[0053] In this embodiment, when the energy calculation result and the preprocessing information are sent to the communication module synchronously, since it is necessary to distinguish the two data streams and to protect data security, an information security management module is set before the communication module receives the preprocessing information and the energy calculation result. The information security management module can perform identity authentication of the information interaction object, encryption and decryption of the interaction data, and verification of the integrity and validity of the interaction data, so that information security can be effectively guaranteed, and the preprocessing information and the energy calculation result can be distinguished, which is beneficial for the management platform (or sensor network platform) to organize and calculate the data; in this embodiment, the data preprocessing module is set to preprocess the collected natural gas physical data, and the encrypted energy calculation result and the preprocessing information are sent synchronously, so that the management platform (or sensor network platform) can not only directly obtain the energy calculation result, but also realize remote energy metering and accounting through the obtained preprocessing information, realize synchronous metering between the device end and the platform end, facilitate mutual verification and analysis of the metering results, and improve metering accuracy.

[0054] The communication module includes a streaming unit, which is used to perform the following steps:

[0055] Acquire communication data in real time, and acquire a timestamp corresponding to the time when the communication data is received in real time;

[0056] The timestamp is combined with the corresponding communication data to form data to be sent;

[0057] The data to be sent are pushed in sequence according to the order of timestamps, and the time interval between each data to be sent is consistent with the time interval of the timestamps.

[0058] In this embodiment, the preprocessing information used by the energy calculation module for calculation corresponds to the preprocessing information directly sent by the data preprocessing module to the information security management module, and the corresponding preprocessing information and energy calculation result are packaged and sent in the information security management module or the communication module. Since the communication data is the energy calculation result and preprocessing information after encryption and decryption, when the timestamp is added to the communication data, the corresponding energy calculation result and preprocessing information will share the same timestamp. When the management platform needs to verify the energy calculation result, it only needs to find the corresponding energy calculation result and preprocessing information according to the timestamp, which can not only facilitate the management platform (or sensor network platform) to verify the energy calculation result, but also enable the management platform (or sensor network platform) to achieve the purpose of backup energy calculation.

[0059] A buffer unit is also provided in the communication module, and the buffer unit is used to maintain a data queue, and the data queue is used to store a section of data to be sent. After the data queue is full, the communication module sends the data to be sent in the order of timestamps.

[0060] When the data queue of the buffer unit is full, new data to be sent enters the data queue and is placed at the end of the queue, and the data to be sent at the head of the queue is sent.

[0061] In this embodiment, the buffer unit is used to receive the data to be sent from the streaming unit, and complete the sending of the communication data as a sending channel for the data to be sent.

[0062] The interval between the real timestamps of two adjacent communication data is taken as the real time difference. After pushing a piece of data to be sent, the next piece of data to be sent is sent after waiting for the real time difference.

[0063] The real timestamp in this embodiment records the real time, while the timestamp records the sequential time. Taking the real timestamp of the first data to be sent as the starting point, the interval time of the subsequent sending of the data to be sent is calculated according to the time difference between the real timestamp of the data to be sent and the starting point.

[0064] The natural gas data acquisition system includes a flow sensor, a pressure sensor and a temperature sensor, and the flow sensor, pressure sensor and temperature sensor are all connected to the data preprocessing module. The data preprocessing module can calculate the operating flow rate of natural gas through the natural gas physical data collected by the flow sensor, pressure sensor and temperature sensor, and realize the conversion of the operating flow rate to the standard flow rate.

[0065] This embodiment queues the communication data by storing the timestamp together with the communication data, and sends the communication data in sequence according to the order of the timestamps, thereby effectively organizing the communication data sending method, avoiding the blockage of the data sending channel of the communication module, and enabling the management platform (or sensor network platform) to obtain more complete communication data.

[0066] In this embodiment, a buffer unit is constructed to effectively establish a data queue. Through the integration of the data queue, the communication data can be effectively sent in the order of timestamps. Due to the existence of the data queue, the situation where a large amount of communication data flows in at the same time is avoided, thereby reducing the burden of sending communication data. The data queue can make the sending of communication data more orderly.

[0067] In this embodiment, by buffering the data queue in the buffer unit, the communication data can enter the data queue for sorting before sending. In addition to making the sending of communication data more orderly, the data queue can also effectively avoid the loss of intermediate data. Since the communication data in this embodiment is arranged according to timestamps, and the timestamps are independently obtained when the communication data is obtained, if the timestamp is missing in the data queue, it proves that there is data loss here, thereby avoiding ignoring the data packet loss phenomenon in the data queue.

[0068] This embodiment does not use the interval time between two pieces of data to be sent as the standard as the time interval for data transmission, which effectively avoids the measurement error of the interval time. Instead, by taking the timestamp of sending the first piece of data to be sent as the starting point, the time for subsequent sending of the data to be sent is calculated according to the time difference between the timestamp of the data to be sent and the starting point, thereby eliminating the time error between each communication data and the previous communication data, thereby obtaining smoother data transmission and more effectively avoiding data channel congestion and packet loss.

[0069] In this embodiment, the communication module is connected to a combustible gas detection alarm module, which is used to detect the leakage status of pipeline natural gas and output alarm information. It can effectively detect combustible gas leakage in the device and send alarm information to avoid the harm caused by natural gas leakage.

[0070] The calorific value analysis and processing system comprises a calorific value analysis and processing module, the input end of which is connected to a sample gas processing system and a standard gas processing system, wherein:

[0071] The input end of the sample gas processing system is connected to a sample gas controller, and the input end of the sample gas controller is connected to a sample gas collection interface. The sample gas processing system is used to remove impurities from the collected natural gas, and the calorific value analysis and processing module calculates the unit calorific value of the natural gas after the impurities are removed, and transmits the calculation result to the data preprocessing module;

[0072] The input end of the standard gas processing system is connected to the standard gas collection port. The standard gas processing system is used to remove impurities from the collected standard gas. The calorific value analysis and processing module calculates the calorific value of the standard gas after impurities are removed, and compares the calculation result with the standard value of the calorific value of the standard gas to achieve calibration of the calorific value analysis and processing module.
