Description

Technical Field

[0001] The present invention relates to the technical field of monitoring model establishment, and in particular to a gas monitoring display system and method based on a three-dimensional model. Background Art

[0002] Existing gas monitoring display systems based on three-dimensional models provide intuitive spatial visualization by combining gas concentration data with real-time three-dimensional environmental models.

[0003] For example, the prior art discloses a method and device for constructing a gas mutual drive model, a storage medium and an electronic device, the method comprising: scanning a porous medium to obtain a porous medium structural image; constructing a pore network model based on the porous medium structural image; and constructing a gas mutual drive model based on the pore network model, while ensuring the heterogeneous distribution characteristics of the porous medium, displaying the transient distribution characteristics of the gas in a three-dimensional visualization manner, and being able to quantitatively measure the gas flow characteristics and mutual drive efficiency, and visualize and quantitatively display the transient gas mutual drive process that is difficult to capture under laboratory conditions in a manner based on a heterogeneous pore network, and evaluating the gas displacement characteristics through pressure distribution, gas phase distribution and gas flow, thereby realizing the tracking and description of multiphase fluid transport and exchange behavior, and being able to clarify the interaction between gases in carbon sequestration, hydrogen storage, and gas reservoir development during underground energy storage and mining.

[0004] The existing technologies currently demonstrated in gas monitoring mainly rely on various sensors to collect gas data in real time, and convert these data into intuitive graphics and charts through software platforms so that users can quickly understand information such as gas concentration, type and flow rate, and make corresponding responses and decisions.

[0005] However, although this gas mutual drive model can display the gas distribution characteristics through three-dimensional visualization and quantitatively measure the flow rate and mutual drive efficiency, its simulation of the complexity of actual underground conditions may not be accurate enough, especially when dealing with the heterogeneity of porous media and multiphase fluid exchange behavior. The model requires a lot of computing resources, resulting in untimely model updates. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] like Figure 1 As shown, it is a structural block diagram of a gas monitoring and display system based on a three-dimensional model according to an embodiment of the present invention. The present invention provides a gas monitoring and display system based on a three-dimensional model, including:

[0047] A monitoring environment acquisition module is used to obtain actual building information of the environment to be monitored, and determine several sub-monitoring environments of the environment to be monitored and corresponding three-dimensional information according to the actual building information;

[0048] A gas monitoring module, which is connected to the monitoring environment acquisition module and is used to continuously acquire gas information in each of the sub-monitoring environments, the gas information including gas flow rate, gas type and corresponding gas concentration;

[0049] A model generation module, which is connected to the monitoring environment acquisition module and the gas monitoring module respectively, and is used to construct a three-dimensional model of the environment to be monitored in the model space, and to update the gas display state in the sub-model of the three-dimensional model with an initial update cycle according to the gas information;

[0050] A model updating module, which is connected to the monitoring environment acquisition module, the gas monitoring module and the model generation module respectively, and is used to determine the update method and update cycle of each sub-model in the three-dimensional model according to the gas information detection result, and determine the integration method of each sub-model according to the change amount of the gas information;

[0051] A monitoring and early warning module is connected to the model updating module and the gas monitoring module respectively, and is used to send early warning information to the corresponding sub-monitoring environment according to the display status of the three-dimensional model.

[0052] In implementation, the initial update cycle is 5 to 10 seconds. The higher the gas danger level displayed by the monitoring, the smaller the time interval of the initial update cycle. The adjusted update cycle can be less than 5 seconds.

[0053] The present invention does not limit the specific structure of the model generation module and the model update module, which can be composed of logic components, and the logic components include a field programmable processor, a computer, and a microprocessor in the computer.

[0054] The present invention realizes the accurate division of the monitored environment and the dynamic monitoring of real-time gas information through the coordinated work of the monitoring environment acquisition module, the gas monitoring module, the model generation module, the model update module and the monitoring and early warning module. The system can intelligently adjust the update mode and cycle of each sub-model according to information such as gas type, concentration, flow rate, etc., optimize resource allocation, and improve monitoring efficiency. At the same time, the system can also intelligently determine whether to integrate the model according to the change in gas information and the position relationship of the sub-model, reduce the amount of data processing, and reduce the complexity of calculation. In addition, the monitoring and early warning module can issue early warning information in time according to the display status of the three-dimensional model, providing strong support for safety management.

[0055] Furthermore, the present invention improves the accuracy and response speed of gas monitoring, reduces system resource consumption, and enhances the ability of environmental safety monitoring through an intelligent monitoring and early warning mechanism.

[0056] In detail, the environment to be monitored includes several sub-monitoring environments;

[0057] The sub-monitoring environments are independent of each other and have no overlapping parts.

[0058] In this embodiment, by dividing the environment to be monitored into several non-overlapping sub-monitoring environments, the system can monitor and manage each sub-environment more accurately and optimize resource allocation. Since the sub-monitoring environments are independent of each other, the system can set monitoring sensors according to the specific needs of each sub-environment. Independently monitoring each sub-environment can reduce the interference of gas flow between different environments on the monitoring results and improve the accuracy of monitoring data. In addition, when a problem occurs in a sub-monitoring environment, since they are independent of each other, the system can quickly locate the problem area, facilitate troubleshooting and maintenance, and reduce interference with the entire monitoring system. The system can also flexibly add or remove sub-monitoring environments according to actual needs, or adjust existing sub-environments to adapt to different monitoring needs and environmental changes.

[0059] like Figure 2 As shown, it is a structural block diagram of a gas monitoring module according to an embodiment of the present invention, and the gas monitoring module includes:

[0060] A gas monitoring sensor group, which includes a plurality of gas concentration sensors for monitoring the gas types and corresponding gas concentrations in the sub-monitoring environment;

[0061] A gas flow rate monitoring unit is connected to the gas monitoring sensor group and is used to monitor the gas flow rate of the sub-monitoring environment.

[0062] In implementation, the number of gas concentration sensors in the gas monitoring sensor group is equal to the total number of sub-monitoring environments; the number of gas flow rate sensors in the gas flow rate monitoring unit is twice the total number of sub-monitoring environments;

[0063] In this embodiment, the gas concentration sensor preferably uses a photoelectronic gas sensor, including a light source, a light receiver, and an optical transmission path. The photoelectronic gas sensor usually detects the concentration of the gas based on the absorption or scattering characteristics of the gas molecules to light of a specific wavelength. When the gas passes through this path, the light interacts with the gas molecules, and different gas molecules absorb light of different wavelengths. This principle is based on the absorption characteristics of the gas to a specific wavelength of light. For example, carbon dioxide (CO2) absorbs 4.3 microns of infrared light, and the sensor calculates the concentration of the gas by measuring the amount of light absorbed in the gas. In practice, the light emitted by the light source passes through the gas sample, and the receiver measures the change in light intensity passing through the sample. According to the degree of change in light intensity, the sensor can calculate the concentration of the gas. The model selection of the photoelectronic gas sensor is determined based on the three-dimensional information of the sub-monitoring environment. The monitoring range of the photoelectronic gas sensor is greater than the volume of the sub-monitoring environment in which it is located. This is a prior art and will not be described in detail.

[0064] In this embodiment, the gas concentration sensor can be a thermal gas flow sensor, a turbine flow sensor, a differential pressure flow sensor, or an ultrasonic flow sensor, etc., which can detect the indoor gas flow rate. When setting the gas concentration sensor, it is set according to the provisions of the confined space operation safety guidance manual. In the vertical direction, the number of detection points should not be less than 3, and the distance between the detection points should not exceed 8 meters; in the horizontal direction, the number of detection points should not be less than 2, and the distance between the far end point and the confined space entrance and exit should not be less than 2 meters. For the sub-monitoring environment with known three-dimensional information, it is a prior art to determine the setting method and number of gas concentration sensors, and no specific limitation is made.

[0065] In detail, the model generation module constructs a three-dimensional model of the environment to be monitored in a simulated space according to the actual building information of the environment to be monitored, and determines a sub-model of each sub-monitoring environment in the three-dimensional model according to each sub-monitoring environment and the corresponding three-dimensional information.

[0066] In this embodiment, the corresponding virtual three-dimensional model can be called in a database that pre-stores several building models according to the actual building information, and the called virtual three-dimensional model can be adjusted according to the size information corresponding to the actual building information to place the model in the model space to complete the establishment of the three-dimensional model. The size is then adjusted according to the three-dimensional information of the monitoring environment and the position of the corresponding sub-model in the three-dimensional model is determined. This will not be repeated here.

[0067] In detail, the model generation module updates the gas display state in each sub-model at an initial update cycle according to the gas information;

[0068] The gas display state includes an overall display state and a dispersed display state.

[0069] In implementation, the gas types include toxic and harmful gases (carbon monoxide, hydrogen sulfide, formaldehyde, benzene and benzene derivatives, etc.), combustible gases (methane, hydrogen, liquefied petroleum gas), volatile organic compounds and oxygen, etc. The gas category is the gas category detected by the sensor, and each gas category includes several gas categories;

[0070] The overall display state displays the combined monitoring results of each gas type, and the scattered display state displays the monitoring results of each type of gas.

[0071] The model generation module updates the gas display status in real time and provides two modes: overall display status and dispersed display status. It comprehensively presents monitoring data including various gases. The overall display status can grasp the gas environment overview at a macro level, while the dispersed display status deeply displays the specific monitoring results of each type of gas, enhancing the flexibility and accuracy of monitoring, especially the real-time tracking and response capabilities of multiple gases in complex environments. It not only improves the readability and availability of monitoring data, but also optimizes resource allocation. The system can quickly identify potential hazardous gas accumulation areas and conduct detailed analysis of the risks of different types of gases, so as to more effectively conduct risk assessment and provide a data basis for subsequent decision-making.

[0072] In detail, in the model generation module:

[0073] The gas display state is an overall display state including displaying various types of gases in the sub-model as different filling colors, displaying the corresponding concentrations of various types of gases in the sub-model as different filling densities, and displaying the flow velocity of the gas in the sub-model along the gas flow direction;

[0074] The gas display state is a dispersed display state including displaying various types of gas in the sub-model as different filling colors, displaying the corresponding concentrations of various types of gas in the sub-model as different filling densities, and displaying the gas flow rate in the sub-model along the gas flow direction.

[0075] In implementation, the filling colors of various types of gases in the overall display state are different, and the filling colors of various categories of gases in the scattered display state are different. The same type of gas or the same category of gas is displayed using the same color system, and the depth or transparency of the color is selected according to the size relationship of the data for display, which can more intuitively display the size changes and distinguish various data types.

[0076] The gas flow velocity is displayed along the gas flow direction in the sub-model. The flow velocity is represented by a flow vector, which can characterize the velocity value of the gas flow velocity at different positions and the gas flow direction.

[0077] The model generation module sets different display parameters and different display methods for different dynamic information, which is used to display different dynamic information corresponding to various gas information, and can intuitively and real-timely reflect the operation status of the power network at each monitoring point.

[0078] In detail, the model updating module determines the updating method of each sub-model in the three-dimensional model according to the gas type and the corresponding gas concentration; the model updating module determines the updating period of each sub-model according to the gas flow rate and the gas concentration.

[0079] During implementation, if the gas concentration corresponding to the gas type is greater than the corresponding safety standard, the update frequency of the corresponding sub-model is increased. If the corresponding gas concentration is within the corresponding safety standard and the allowable range for 7 to 10 consecutive update cycles, the update frequency of the corresponding sub-model is delayed.

[0080] If the gas flow rate and gas concentration do not change for 7 to 10 consecutive update cycles, the update cycle becomes twice the original update cycle. If the gas concentration corresponding to the gas type is greater than the corresponding safety standard or the gas flow rate continues to change, the update frequency is the same as the sensor change frequency in the subspace.

[0081] The model update module can dynamically adjust the update method according to the gas type and the corresponding gas concentration, and determine the update cycle according to the gas flow rate and concentration, so as to achieve more accurate and efficient gas monitoring. Specifically, when the gas concentration exceeds the safety standard, the system will increase the update frequency to respond to potential risks more quickly; if the gas concentration continues to be within the safe range, the system will delay the update frequency to reduce unnecessary resource consumption.

[0082] See also Figure 3 As shown, it is a logic diagram of integrating sub-models in an embodiment of the present invention, and the model updating module determines whether to integrate the sub-models according to the change amount of the gas information of the sub-models and the position relationship of the sub-models;

[0083] If the sub-model meets the model integration condition, the sub-model is integrated;

[0084] The model integration condition is that the change in gas information is within a change threshold range and each sub-model is in an adjacent relationship.

[0085] In the implementation, the gas velocity changes within ±0.01 to ±0.05 m / s, and the gas concentration change rate does not exceed ±5% within 3 hours, and the change amount of the gas information is determined to be within the change threshold range. After the sub-models are integrated, the sub-models integrated into one are updated synchronously.

[0086] It can be understood that by integrating adjacent sub-models, the number of models that the system needs to process and update can be reduced, thereby improving the efficiency and response speed of data processing. Reducing the number of sub-models can reduce the computational complexity of the overall system, reduce the computational burden, and make resources (such as sensors, computing power, etc.) more concentrated and efficient. Use, avoid waste of resources.

[0087] In detail, the monitoring and early warning module determines whether to issue an early warning message according to the display status of the three-dimensional model, and issues an early warning message to the corresponding sub-monitoring environment according to the position of the sub-model.

[0088] In this embodiment, if the gas concentration corresponding to the gas type is greater than the corresponding safety standard, the filling density of the display state of the three-dimensional model is greater than the filling density corresponding to the safety standard, and it is determined that an early warning message is issued.

[0089] like Figure 4 As shown, it is a flow chart of a gas monitoring display method based on a three-dimensional model according to an embodiment of the present invention. The present invention also provides a method, including:

[0090] Step S1, the environment acquisition module acquires actual building information of the environment to be monitored and several sub-monitoring environments of the environment to be monitored and corresponding three-dimensional information;

[0091] Step S2, the gas monitoring module obtains gas information in each of the sub-monitoring environments;

[0093] Step S4, the model updating module determines the updating method and updating cycle of each sub-model in the three-dimensional model according to the gas information detection result, and determines the integration method of each sub-model according to the change amount of the gas information;

[0094] Step S5: the monitoring and early warning module sends early warning information to the corresponding sub-monitoring environment according to the display status of the three-dimensional model.

[0095] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
