Description

Technical Field

[0001] The present invention relates to the technical field of gas detection, and in particular to a regional gas detection system based on star flash technology. Background Art

[0002] For gas detection systems within a region, such as those in industrial plants, devices like gas detectors that support positioning and networking require the use of traditional technologies such as Bluetooth, Zigbee, LoRa, WiFi network connections, and cellular networks to achieve precise positioning and networking. Bluetooth and Zigbee technologies suffer from insufficient positioning accuracy, require dense node deployment, have limited coverage, and are susceptible to signal interference in complex industrial environments. LoRa technology suffers from poor positioning accuracy, failing to meet meter-level positioning requirements, and exhibits significant network data transmission delays and insufficient real-time performance. WiFi technology requires the deployment of numerous access points (APs) to provide Wi-Fi coverage throughout the area. Sensor nodes consume high power and require frequent charging, and positioning relies on AP deployment, making it unsuitable for monitoring scenarios without infrastructure. Cellular networks rely on mobile communication base stations for positioning, resulting in poor positioning accuracy and the need for an additional positioning module, leading to high system costs.

[0048] The LED light is controlled by the intelligent gas detection main circuit board, and the light is used to alert people around.

[0049] like Figure 2 As shown, the regional gas detection system based on star flash technology of the present invention includes:

[0050] Several intelligent gas detection devices equipped with integrated synaesthesia star flash modules collect gas concentration and posture information and upload the collected information;

[0051] The smart gateway equipped with the Star Flash module communicates wirelessly with the smart gas detection equipment;

[0052] Cloud server; the cloud server is an IOT server, which communicates wirelessly with the smart gateway, receives and processes the gas concentration and posture information transmitted by the smart gateway;

[0053] The information collected by several intelligent gas detection devices is preprocessed to correct deviations and align them in space and time. The data is then correlated through distributed joint probabilistic data association and distributed multiple hypothesis testing to obtain the location or attributes of the intelligent gas detection devices for target differentiation and tracking. A decision is then made and sent to the data center.

[0054] The data center is wirelessly connected to the IOT server; it has a PC interface operating platform, which can perform graphical area division according to area size and function, and color-code dangerous areas based on gateway data to indicate gas leaks in a certain area or at a specific point.

[0055] Several of the intelligent gas detection devices communicate with the intelligent gateway equipped with the Star Flash module through Star Flash wireless communication to upload gas concentration collection information, alarm information, and posture information; the intelligent gateway equipped with the Star Flash module is connected to the cloud server through 5G wireless communication to upload the information collected by the gas detection device to the cloud server. The Star Flash module is used to connect to the gateway equipped with Star Flash technology or other intelligent gas detection devices, and to transmit data between the connected device and the MCU; Star Flash technology adopts Star Flash SLE low power consumption + SLB high speed + SLP precise positioning and synaesthesia integrated technology. The number of networking nodes of multiple intelligent gas detection devices can support more than 50 units, and users can select and connect them according to their needs.

[0056] Through a multimodal data preprocessing mechanism, IOT converts data into a standard normal distribution or uniform distribution according to the statistical characteristics of the data, and maps data values ​​of different dimensions into the same numerical range to eliminate the weight distribution bias caused by differences in the range of different eigenvalues, adjust the distribution of data to make it more consistent with the preset values ​​of certain algorithms, improve the ability to process large-scale and high-dimensional data, and enhance the ability to process data with missing data or a large number of outliers.

[0058] Deploy multimodal data sources for data collection, pre-process data at sub-nodes, and then connect to the data fusion center system through unified communication. The first level of processing is sub-object segmentation, which pre-processes data to correct deviations and align them in space and time. The second level of processing is object refinement, which correlates data to obtain the location or attributes of the target. The results obtained include target differentiation and target tracking. The third level of processing is target process assessment, which conducts correlation analysis on objects or events and estimates their contextual relationships in the work environment. In fact, it is mainly to assess the importance of the target in a specific environment. The fourth level of processing is fusion data assessment, which predicts the current situation to conduct event prediction, intent estimation, and consequence analysis, and further evaluates the refined object targets. The fifth level of processing is fusion process improvement, which evaluates the ongoing fusion process and provides suggestions, such as task priority and the allocation of available resources.

[0059] Furthermore, each data source node is processed independently, with the results sent to the fusion node. Each fusion node is responsible for processing the information received from other nodes. This structure provides more flexible configuration, allowing for a single fusion node or multiple intermediate fusion nodes. In a distributed data fusion system, each sensor or data source has its own local processor.

[0060] Further, such as Figure 3 As shown, data association is usually performed before state estimation.

The present invention associates data through distributed joint probabilistic data association and distributed multiple hypothesis testing.

[0061] Furthermore, by combining information from multiple data sources, advanced analysis and reasoning are used to generate and ultimately execute decisions. During the fusion process, the system makes decisions based on predefined rules and policies, as well as the information generated after fusion. These decisions may involve multiple aspects such as target identification, classification, tracking, and prediction. Once a decision is made, the system will issue dynamic instructions based on the decision results according to different application scenarios. The execution process involves the coordination and cooperation of multiple systems and components to ensure the effective implementation of the decision, and the decision is adjusted and optimized based on real-time feedback and new information.
