Description

Technical Field

[0001] The present invention relates to the field of gas monitoring, and in particular to a gas gateway system based on the Internet of Things. Background Art

[0002] Currently, gas management still relies largely on manual inspections, which are inefficient and slow to respond. Due to a lack of real-time monitoring, many hidden dangers go undetected, easily leading to accidents. Furthermore, data is not shared between departments, leaving them operating independently. This leads to difficulties in coordination and delayed emergency response when problems arise.

[0003] With the rapid development of IoT technology, front-end sensors are increasingly being used in various fields. However, existing gas gateway sensor data collection and reporting systems often suffer from insufficient data processing capabilities, low reporting efficiency, and difficulty adapting localized products, making them unable to meet the complex and ever-changing needs of IoT applications. Therefore, it is necessary to design an intelligent gateway device based on front-end sensors to efficiently collect, analyze, and report sensor data to the IoT cloud platform. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the existing technology and propose a gas gateway system based on the Internet of Things. The gateway system is based on the research of domestic Rockchip microchip and domestic Kylin operating system.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a gas gateway system based on the Internet of Things, including a front-end sensor module, a data acquisition module, a data processing module, a data reporting module, and a control module. The front-end sensor module is composed of multiple front-end sensors connected to each other, and is used to monitor environmental parameters in real time and send data signals; the data acquisition module is used to receive the data signals sent by the front-end sensors and convert them into digital signals; the data processing module is used to pre-process, analyze and filter the collected digital signals to extract valuable information; the data reporting module is used to send the processed data to the Internet of Things cloud platform via a wired or wireless network; the control module is responsible for coordinating the work of each module to ensure the normal operation of the entire system.

[0006] Furthermore: the data acquisition module can communicate with the front-end sensor using multiple communication protocols.

[0007] Furthermore: the data processing module can use algorithms such as machine learning to analyze and filter data.

[0008] Furthermore: the data reporting module can use a variety of wireless or wired network technologies to transmit data.

[0009] The present invention has the following beneficial effects:

[0010] Compared with existing technologies, this IoT-based gas gateway system achieves efficient utilization of front-end sensor data through the data collection, processing and reporting functions of the intelligent gateway system; and provides users with convenient data management and decision-making support through the storage, analysis and display functions of the IoT cloud platform.

[0011] Without changing or interfering with existing sensors and alarm device controllers, this invention achieves "senseless" integration in a low-cost, easy-to-implement, and highly reliable manner. This converges and integrates previously isolated device data, forming a closed-loop remote monitoring and intelligent early warning mechanism. This will significantly lower the barrier to digital transformation and upgrades for traditional gas stations, providing technical support for the gas industry's transition to networking, intelligentization, and localization.

[0012] The system of the present invention has a simple structure and is easy to implement, and can be widely used in fields such as environmental monitoring, smart home, and agricultural Internet of Things. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of module connection of the present invention; DETAILED DESCRIPTION

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0015] Reference Figure 1 The present invention provides a gas gateway system based on the Internet of Things, including a front-end sensor module, a data acquisition module, a data processing module, a data reporting module, and a control module. The front-end sensor module is composed of a plurality of front-end sensors connected in a network, and is used to monitor environmental parameters in real time and send data signals.

[0016] The data acquisition module is used to receive data signals sent by front-end sensors and convert them into digital signals. The data acquisition module is responsible for docking with front-end sensor devices and receiving various raw data signals sent by front-end sensors. It contains multiple high-precision ADC channels and a high-impedance photoelectric isolation circuit in front to safely "mirror" collect analog signals such as 4-20mA. It also integrates multiple RS485 / RS232 physical interfaces for direct connection to digital sensors that comply with protocols such as Modbus-RTU.

[0017] The data processing module is used to pre-process, analyze and filter the collected digital signals to extract valuable information. The data processing module is responsible for sending the locally processed data in a custom data format through a wired or wireless network securely and reliably. It integrates wireless (Wi-Fi / 4G) and wired (standard Ethernet) interfaces to provide a physical channel for connecting to the Internet.

[0018] The data reporting module is used to send the processed data to the Internet of Things cloud platform via a wired or wireless network.

[0019] The control module is responsible for coordinating the work of each module to ensure the normal operation of the entire system.

[0020] The core operating principle of the IoT-based gas gateway system described in this invention is that it serves as an intelligent hub deployed on-site at a gas station, independently and completely executing a set of automated processes from "data acquisition" to "intelligent analysis" to "response control." It aims to securely and cost-effectively connect previously isolated sensor data to the network and, through local intelligent processing, enhance the safety monitoring level of the gas station. Its complete workflow can be divided into several key stages: data acquisition, data analysis, decision-making, and response control. Specifically,

[0021] 1. Data Collection Phase: During this phase, the gateway's core mission is to securely, efficiently, and compatibly acquire data from all on-site sensors. Through a specially designed non-intrusive data collection interface, it "mirrors" a copy of the data from existing sensor signal lines. This process is achieved through electrical isolation technology, ensuring no interference with existing equipment or alarm systems. This interface is capable of simultaneously processing multiple signal types, including 4-20mA analog signals and digital signals such as Modbus RTU.

[0022] 2. Data Analysis: The gateway leverages its local computing power to perform in-depth processing and intelligent analysis on the collected standardized data. Its core objectives are twofold: first, converting data from diverse sources and formats into unified, standardized physical quantities that the system can understand; second, intelligently analyzing these standardized physical quantities to determine if there are security risks. This phase utilizes the system's built-in data analysis engine to assess risk, including static threshold analysis, dynamic trend analysis, and multi-dimensional correlation analysis.

[0023] 3. Decision-making Phase: Based on the results of the data analysis phase, the gateway device's alarm policy engine assesses the current system status and determines the necessary actions. When the data meets the risk event criteria set by the pre-set rules, the gateway autonomously makes an emergency response decision. This decision is independent of the cloud platform or any external intervention, ensuring autonomous decision-making in extreme situations such as network outages. This decision includes the severity of the alarm to be triggered and whether immediate local control is required.

[0024] 4. Response control phase: The gateway converts the decision-making results into actual physical actions or interactive information data. The response behaviors mainly include the following aspects:

[0025] 1) Local closed-loop control: For emergency alarms from internal decisions, the gateway will immediately call the hardware interface locally to drive the connected relay control and execute emergency plans such as automatically closing valves and activating sound and light alarms, achieving risk disposal in seconds.

[0026] 2) Intelligent Risk Reporting: Dynamic reporting strategies are implemented based on decision-making outcomes. When the system is stable, only aggregated data is reported periodically. When an alarm occurs or in response to a remote query, incident response or status data is immediately reported.

[0027] 3) Operation records and traceability: All response control actions, whether automatically executed by the system or manually intervened by on-site personnel, will be recorded in detail by the system to form a complete operation log to ensure that every action is traceable.

[0028] This gas gateway system utilizes a modular hardware architecture and a unified interface bus design, treating the gateway device as a scalable hardware platform for edge computing and environmental sensing, capable of connecting to various sensors and environmental perception modules. The main control unit utilizes a low-power, high-performance microcontroller (a domestically produced MCU) equipped with a lightweight real-time operating system (a domestically produced system: LiteOS), responsible for task scheduling, data processing, and communication control for the entire gateway. The device integrates multiple communication methods, including I2C, SPI, UART, Ethernet, Wi-Fi, and ultra-high frequency, providing a unified loading method for various register devices, intelligent sensing modules, and data interaction functions. External expansion modules can be flexibly selected based on site needs to achieve environmental perception, monitoring, and device control.

[0029] Based on the above unified architecture, this gateway has powerful functional expansion capabilities and can flexibly integrate multiple functional modules according to the specific needs of gas stations to build a comprehensive security situation awareness and control system. Specifically, it includes the following aspects:

[0030] 1. The gateway device supports data connection of multiple analog sensors. Through its built-in high-precision ADC interface, it can parallelly collect and process standard industrial analog signals 4-20mA current or voltage signals, enabling real-time monitoring of core data such as tank area pressure, liquid level, and combustible gas concentration in key areas of the station.

[0031] 2. The gateway device supports driving multiple relay control units. Using the GPIO interface isolated by optical coupling, it can safely and reliably perform on-off control of key actuators such as gas emergency shut-off valves, sound and light alarms, and sprinkler cooling systems. It supports cloud-based remote commands and local intelligent linkage.

[0032] 3. The gateway device supports the integration of multiple environmental perception modules. Through standard buses such as I2C / SPI, it can seamlessly mount sensors such as temperature and humidity, digital smoke detectors, etc., to establish real-time monitoring of the site operating environment and provide rich environmental data support for multi-dimensional data fusion analysis.

[0033] 4. The gateway device supports the integration of asset physical security monitoring modules. By docking with the IMU six-axis sensor module, it can sense in real time whether the gateway itself or its fixed key equipment has abnormal tilt, vibration, or illegal displacement.

[0034] 5. The gateway device supports the integration of a contactless authentication module. By connecting to a near-field communication (NFC, 6B, etc.) card reader, it can authenticate the identity of on-site operation and maintenance personnel, provide electronic security credentials for key operations such as parameter modification and equipment start and stop, and achieve closed-loop management and full traceability of operational behaviors.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
