Description

Technical Field

[0001] The present invention relates to the field of gas monitoring and alarm, and more specifically to an ultrasonic gas working status monitoring method, system and storage medium based on digital twin. Background Art

[0002] In daily use of gas, if you forget to turn off the gas and let it work for a long time, the consequences are very serious. In the mildest case, the pot will be burned, and in the worst case, it will cause a fire, resulting in catastrophic consequences.

[0003] The gas dry-burn prevention monitoring currently used is mainly applied to gas stoves, that is, using temperature sensors to monitor the temperature of the pot body and turn off the fire when the temperature is too high. This method has several problems: 1. During the long-term stewing process, the temperature of the pot body may be too high, causing misjudgment; 2. The temperature sensor placed on the pot body is exposed to high temperature for a long time and has a short lifespan; 3. Due to the different materials of the pot body, this method has a large error.

[0004] With the continuous development of technologies such as the Internet of Things and big data, the gas industry is also gradually becoming intelligent. By installing sensors, collecting data and analyzing them, real-time monitoring and early warning of gas production, transportation and use can be achieved to improve safety and efficiency. However, the above technical solution requires large-scale modification of gas pipelines, which is costly and not conducive to implementation. Therefore, how to achieve simple and efficient gas monitoring and improve monitoring efficiency still requires continued research by technical personnel in this field. Summary of the invention

[0005] In view of this, the present invention provides an ultrasonic gas working status monitoring method, system and storage medium based on digital twin, which can improve the safety of gas use, monitoring accuracy, intelligent management level and reduce maintenance costs.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A method for monitoring the working state of ultrasonic gas based on digital twins comprises the following steps:

[0008] Obtain the gas working status, and build a digital twin model of different gas working states based on digital twin technology. The gas working status includes the gas stewing content and the pots used for stewing;

[0009] Collect historical experience data of abnormal gas operation, and map the abnormal operation indicators corresponding to the abnormal operation to the twin models of gas operation status data;

[0010] According to the actual gas usage status, the current digital twin model is selected, and the gas flow in the gas pipeline is monitored in real time using ultrasound, and the flow time is recorded, and the gas flow and flow time are mapped to the current digital twin model;

[0011] The current digital twin model determines whether there are abnormal working indicators based on the gas flow rate and flow time. If there is an abnormality, an alarm command is issued and the gas is shut off.

[0012] Optionally, it also includes setting a gas index threshold in the gas working environment in the digital twin model of different working states, using a gas sensor to collect the gas index in the gas working environment in real time, comparing the gas index with the gas index threshold, and determining whether there is a gas leakage problem.

[0013] Optionally, ultrasound can be used to monitor the gas flow in the gas pipeline in real time. The specific principle is: when there is no gas flowing in the gas pipeline, the time from the ultrasonic transmitting probe sending out the ultrasonic wave to the ultrasonic wave receiving the ultrasonic wave is fixed or fluctuates very little. When gas flows in the pipeline, the ultrasonic wave will be accelerated, and the time from sending out the ultrasonic wave to receiving the ultrasonic wave will be reduced. The gas consumption is judged by the degree of reduction in the detection time.

[0014] Optionally, the abnormal working indicators include abnormal pressure, abnormal flow, and abnormal temperature.

[0015] Optionally, it also includes mapping abnormal indicators to the data twin model according to mapping rules to form a visual display of abnormal status; real-time monitoring of abnormal status in the data twin model, and timely issuance of early warning and alarm information.

[0016] Optionally, it also includes setting different equipment working hours in the digital twin model under different gas working conditions, and making real-time reminders based on the working hours.

[0017] An ultrasonic gas working status monitoring system based on digital twin, comprising:

[0018] Digital twin model building module: used to obtain the working status of gas, and build digital twin models of different working status of gas based on digital twin technology. The gas working status includes the content of gas stewing and the pots used for stewing;

[0019] Digital twin model data improvement module: used to collect historical experience data of abnormal gas operation, and map the abnormal operation indicators corresponding to the abnormal operation to the data twin models of different gas operation states;

[0021] Gas anomaly judgment module: The current digital twin model is used to judge whether there are abnormal working indicators based on the gas flow and flow time. If there is an abnormality, an alarm command is issued and the gas is shut off.

[0022] Optionally, the real-time gas monitoring module includes an ultrasonic receiving probe and an ultrasonic transmitting probe. When there is no gas flowing in the gas pipeline, the time from the ultrasonic transmitting probe emitting an ultrasonic wave to the ultrasonic wave being received is fixed or fluctuates very little. When there is gas flowing in the pipeline, the ultrasonic wave will be accelerated, and the time from the ultrasonic wave being emitted to the ultrasonic wave being received will be reduced. The gas consumption is judged by detecting the degree of time reduction.

[0023] A computer storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements any one of the steps of a method for ultrasonic gas working status based on digital twins.

[0024] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides an ultrasonic gas working status monitoring method, system and storage medium based on digital twins, which have the following beneficial effects:

[0025] 1. The present invention combines digital twin technology with ultrasonic monitoring to achieve intelligent management of gas usage status.

Combined with the digital twin model, it can instantly determine whether these changes represent abnormal working conditions, so as to issue an alarm in time and take corresponding safety measures, such as shutting off the gas, to effectively avoid potential safety risks.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The embodiment of the present invention discloses a method for monitoring the working state of ultrasonic gas based on digital twin, such as Figure 1 As shown, the following steps are included:

[0032] Step 1: Obtain the gas working status, and build a digital twin model of different gas working states based on digital twin technology. The gas working status includes gas stewing content and the pots used for stewing;

[0033] Step 2: Collect historical experience data of abnormal gas operation, and map the abnormal operation indicators corresponding to the abnormal operation to the twin models of gas operation status data;

[0034] Step 3: According to the actual gas usage status, select the current digital twin model, use ultrasound to monitor the gas flow in the gas pipeline in real time, record the flow time, and map the gas flow and flow time to the current digital twin model;

[0035] Step 4: The current digital twin model determines whether there are abnormal working indicators based on the gas flow rate and flow time. If there is an abnormality, an alarm command is issued and the gas is shut off.

[0036] The present invention combines the digital twin model and ultrasonic monitoring technology through the above technical solution to provide users with more intuitive and accurate gas usage status information. This helps users better understand gas usage, improve usage efficiency and safety, and thus enhance user satisfaction and loyalty.

[0037] Furthermore, in step one, this embodiment uses an ARM+FPGA solution, wherein the ARM is used for control, algorithm and interface display, and the FPGA is used for ultrasonic monitoring.

[0038] In actual tests, detection rates below 300MHz cannot achieve accurate gas detection. Currently, we use a 500MHz detection frequency and plan to use an 800MHz frequency in the future to achieve more accurate monitoring.

[0039] The present invention constructs a virtual model of gas equipment based on the physical characteristics and working principle of gas equipment by using mathematical modeling, computer simulation and other methods. The influence of gas stewing content and pots on gas usage is considered, and relevant factors are integrated into the virtual model to form a more refined model.

[0040] Furthermore, in step 2, the sources of historical experience data are mainly the following:

[0041] Accident records: Obtain gas accident records from government regulatory departments, industry associations, corporate safety management departments and other channels, including detailed information such as accident type, time, location, cause, and loss.

[0042] Equipment operation and maintenance records: Collect daily operation and maintenance records of gas equipment, including data from equipment status monitoring, troubleshooting, maintenance, etc.

[0043] Environmental monitoring data: Obtain relevant data on the gas usage environment, such as air quality, temperature and humidity, which may affect the working status of the gas.

[0044] Furthermore, in this embodiment, the gas index threshold in the gas working environment is set in the digital twin model of different working states, the gas index in the gas working environment is collected in real time by the gas sensor, and the gas index is compared with the gas index threshold to determine whether there is a gas leakage problem. The digital twin model is used to monitor the operating status of the gas equipment and the changes in the stewing process in real time. When the model detects an abnormal state or potential risk, it will issue a warning message in time and take corresponding safety measures.

[0045] Furthermore, in step three, ultrasound is used to monitor the gas flow in the gas pipeline in real time. The specific principle is: when there is no gas flowing in the gas pipeline, the time from the ultrasonic transmitting probe sending out the ultrasonic wave to the ultrasonic wave receiving the ultrasonic wave is fixed or fluctuates very little. When gas flows in the pipeline, the ultrasonic wave will be accelerated, and the time from sending out the ultrasonic wave to receiving the ultrasonic wave will be reduced. The gas consumption is judged by the degree of reduction in the detection time.

[0046] Furthermore, the abnormal working indicators include abnormal pressure, abnormal flow, and abnormal temperature.

[0047] Specifically, it also includes mapping abnormal indicators into the data twin model according to mapping rules to form a visual display of abnormal status; real-time monitoring of abnormal status in the data twin model, and timely issuance of early warning and alarm information.

[0048] In this embodiment, the digital twin model in different gas working states also includes setting different equipment working hours and making real-time reminders based on the working hours.

[0053] Gas anomaly judgment module: The current digital twin model is used to judge whether there are abnormal working indicators based on the gas flow and flow time. If there is an abnormality, an alarm command is issued and the gas is shut off.

[0054] Furthermore, the real-time gas monitoring module includes an ultrasonic receiving probe and an ultrasonic transmitting probe. When there is no gas flowing in the gas pipeline, the time from the ultrasonic transmitting probe emitting an ultrasonic wave to the ultrasonic wave being received is fixed or fluctuates very little. When there is gas flowing in the pipeline, the ultrasonic wave will be accelerated, and the time from the ultrasonic wave being emitted to the ultrasonic wave being received will be reduced. The gas consumption is judged by detecting the degree of time reduction.

[0055] In addition to detecting the flow of liquid in the pipeline, the above system in this embodiment can also realize gas source shutoff, gas concentration detection in the surrounding environment, air temperature and humidity detection, etc.

[0056] Finally, this embodiment discloses a computer storage medium, on which a computer program is stored. When the computer program is executed by a processor, any one of the steps of the ultrasonic gas working state method based on digital twin is implemented.
