The urban gas pipeline network is an important infrastructure for urban energy transmission, providing core power for household, commercial, and industrial production. However, with the expansion of urban scale and the increasing service life of gas pipelines, safety hazards are becoming increasingly prominent. As a key node in the gas pipeline network, valve wells are prone to methane leakage due to factors such as pipeline aging, loose interfaces, and external corrosion caused by long-term underground enclosed environments. Methane, as a flammable and explosive gas, may accumulate in enclosed spaces even if trace leaks are not detected in a timely manner. Once exposed to a source of fire, it can cause explosions and fires, not only threatening the lives and property safety of surrounding residents, but also causing serious damage to urban transportation and public facilities.

More seriously, traditional gas pipeline monitoring methods have many limitations: on the one hand, relying on manual inspection is inefficient and difficult to achieve 24-hour uninterrupted coverage, and limited by the experience of inspection personnel and the accuracy of detection equipment, it is easy to miss hidden leakage points; On the other hand, early monitoring equipment often used a local storage data mode, which could not be uploaded to the management platform in real time. Staff had difficulty grasping the dynamics of the pipeline network in a timely manner, and often waited until accidents occurred to passively deal with them, missing the opportunity for prevention and control. Against the backdrop of accelerating the construction of smart cities, traditional monitoring methods are no longer able to meet the safety management needs of refined and intelligent urban gas pipelines. How to build an efficient, real-time, and accurate methane leakage monitoring system has become an urgent issue to ensure the safety of urban lifelines.

To solve the industry pain points of methane monitoring in urban gas pipelines, Yiyuntian Electronics has deeply accumulated technology in the field of industrial safety monitoring and launched a targeted solution for methane detection in urban lifeline gas pipelines, providing urban gas.

Yiyuntian ElectronicsValve well leakage monitoring equipment GTYQ-MIC-600-LThe combination with 4G wireless transmission technology is not simply a device overlay, but a full scenario and full cycle safety monitoring solution created based on the actual working conditions of urban gas pipelines. Since the implementation and application of the plan, it has played an important role in gas pipeline network renovation projects in multiple cities across the country, and has delivered an impressive safety response.

From the perspective of device adaptability, the IP68 protection level provides reliable assurance for the stable operation of the equipment in underground valve wells. The environment of underground valve wells in cities is complex, with water accumulation during rainy summers and condensation during low temperatures in winter. In addition, dust and silt accumulate over a long period of time, and ordinary monitoring equipment often fails due to water ingress, moisture, or dust clogging of sensors. The valve well leakage monitoring equipment GTYQ-MIC-600-L, with its IP68 protection capability, can work normally even when immersed in water, effectively resisting dust erosion. Even in environments such as the rainy season in the south and severe cold weather in the north, it can maintain stable detection performance, ensuring that monitoring data is not interrupted or distorted.

The ultra-low power design solves the maintenance problem of traditional devices' frequent power changes. Traditional monitoring equipment often relies on external power sources or short-term battery life, requiring staff to regularly replace them in the well. This not only increases operation and maintenance costs, but also poses safety risks for underground operations. The GTYQ-MIC-600-L valve well leakage monitoring equipment adopts low-power chips and energy-saving algorithms, combined with large capacity long-lasting batteries. It can last for more than 4 years in diffusion detection mode and 3 years in pump suction detection mode. This means that after the installation of the equipment, there is no need for manual intervention in power replacement for several years, greatly reducing the workload and cost of operation and maintenance, while avoiding monitoring gaps caused by power replacement, achieving long-term protection of the gas pipeline network.

The multi-dimensional alarm function of this solution has played an important role in risk warning and equipment security assurance. In addition to the core methane concentration over limit alarm, the equipment also integrates water immersion alarm, anti-theft alarm, displacement alarm, and low battery alarm functions: when the accumulated water in the valve well exceeds the preset safety threshold, the water immersion alarm will be immediately triggered, notifying the staff to promptly investigate and handle the water accumulation problem; If the device encounters malicious damage or theft prevention and relocation alarm, the alarm will be quickly uploaded to the management platform for easy tracking and processing; At the same time, the low battery alarm function displays the remaining battery level in real time through the cloud platform, allowing staff to arrange for battery replacement in advance, ensuring the continuous and stable operation of the equipment, and avoiding monitoring interruptions caused by battery depletion. This multidimensional alarm system not only achieves accurate early warning of methane leaks, but also effectively ensures the safety of monitoring equipment itself, jointly building a dual security guarantee for equipment and pipeline networks.

The application of 4G wireless transmission technology has brought gas pipeline monitoring into the "intelligent era". In the past, monitoring data required manual on-site reading, and there was a serious lag in information transmission; The GTYQ-MIC-600-L valve well leakage monitoring equipment is equipped with a 4G communication module, which can synchronously upload real-time methane concentration data, equipment operation status and other information to the urban gas pipeline management cloud platform. The staff only need to log in to the platform in the office to view the monitoring data of each valve well at any time. If the methane concentration exceeds the standard, the platform will immediately pop up an alarm prompt and accurately locate the location of the leaking valve well, guiding the repair personnel to quickly rush to the scene for disposal.

In addition, the plan also has good scalability and compatibility, and can seamlessly integrate with the urban smart emergency management platform, integrating gas pipeline network monitoring data into the overall urban safety management system. Through big data analysis, management departments can also predict the aging trend of pipeline networks based on historical leakage data, formulate pipeline maintenance plans in advance, and achieve a transition from "passive emergency" to "active prevention and control".

From a long-term perspective of urban development, the Yiyuntian electronic valve well leakage monitoring solution not only solves the pain point of methane monitoring in the current gas pipeline network, but also conforms to the development concept of "safety, efficiency, and intelligence" in smart city construction. It connects scattered valve well monitoring points into a network through technological means, forming a gas pipeline safety monitoring system covering the whole city, providing a solid guarantee for the smooth operation of the city's lifeline. In the future, with the further integration of IoT technology, Yiyuntian Electronics will continue to optimize its solutions, launch more intelligent and efficient monitoring equipment, and help more cities build a "safer and smarter" gas pipeline management system, making the city's lifeline truly a "safe line" and a "reassuring line".
