Product DescriptionProduct DescriptionVehicle-mounted ppb-level gas leak detection systemThe system integrates a mid-infrared spectrometer, BeiDou navigation, Micro meteorl ogical system, AI imaging, and temperature control into a unified mobile platform mounted on a vehi-cle.Operating along municipal roads with natural gas pipelines, it conducts rapid mobile patrols while performing dual gas samplings per second. This enables real-time detection of methane and ethane concentration fluctuations in ambient air, allowing for precise identificatio of natural gas leaks.The BeiDou navigation system can provide accurate map positioning data and trajectory records. Combined with the wind speed and direction data from the micro meteorl ogical system , the system algorithm can accurately mark the location of the suspected leakage point. The system comprises a methane/ethane analyzer (hereinafter referred to as the analyzer), a BeiDou high-precision positioning module, an ultrasonic anemometer, and proprietary leak detection software. It can display a geographic information map showing the detection location and gas concentrations in real-time. The system utilizes mid-infrared laser spectroscopy technology. Methane absorption in the mid-infrared region is 200 times stronger than in the near-infrared, and ethane absorption is 6000 times stronger. The detection chamber is mirrorless, robust, and compact, achieving a 13m absorption path length within an extremely small volume (60cc). This enables ultra-high sensitivity, fast response time, and low power consumption. The filter is externally mounted for easy replacement, resulting in low operating costs. The system simultaneously detects methane and ethane concentrations, calculates the correlation coefficient, determines the gas type, and effectively reduces false alarms. The system displays a real-time detection map containing information such as the route, gas concentration, anomaly alerts, and AI imaging, allowing users to grasp the complete situation at a glance. The upgraded version can distinguish interference sources from CNG/LNG vehicle fuel.SpecificationPARAMETRICDESCRIPTIONMeasurement technologymid-infrared laser absorption spectrumLength of optical cavity13metresSpeed90km/hMedium and analysisEnvironmental Atmosphere,concentrationof methane and ethaneDetection precisionMethane at 1ppb level, ethane at 0.5ppb levelRangeMethane:0.001~10000ppm,Ethane:0.0005~1000ppmDetection frequency2HzMaximum Detection Coverage150 mPositioningBeidou inertial navigation(centimetre level)/GPSOperating power at steady state70W,12VNoise level38~65DecibelOperation interfaceChineseServer and data storageDomestic servers,encrypted data storageEquipment Technical Support24-hour technical supportSoftwareDomestic(Certified with CMMI3)OthersGIS convergenceRange and precision of anemometer0~60m/s,±1mGas intake methodPump suctionpower supplyVehicle-mounted power supplystart-up time after initialization≤1minDetailed PhotosOur AdvantagesThe system generates inspection reports, including the survey map and information on concentration anomaly points, enabling quick understanding of the complete leak detection results.

Can it be managed remotely?Yes. We use a dual-system architecture combining an on-board client and a server. On-board inspection data is uploaded to the server in real time. Administrators can remotely view the overall inspection status by simply logging into the server, making management very convenient.Q2: Can we re-inspect specific past routes?Yes. The on-board system supports loading historical tracks, allowing for accurate re-inspections along the original route, facilitating data comparison and trend analysis.Q3: Can the software process data from different devices or time periods?Yes. The advantage of the server is that it supports multi-device data upload and comprehensive analysis. Inspection data from different devices, time periods, and regions can be integrated and processed to analyze the completeness of pipeline network inspection coverage and determine whether there is overlap in areas of concentrated anomalies.Q4: Does the software have a mapping function? How is it upgraded?Yes. Our inspection system software is deeply integrated with the Geographic Information System (GIS), allowing all data to be displayed intuitively on a map. The software supports remote online upgrades, eliminating the need for on-site manual operations.Q5: What is the core technology of this product? What are its advantages?We utilize leading mid-infrared laser absorption spectroscopy and leak location technology. Its core advantage lies in its compact multi-channel cell structure, which enables an extremely long effective absorption path within an extremely short physical optical path. This results in extremely high detection sensitivity. It can detect changes and correlations in atmospheric methane and ethane concentrations, identify biogas, and determine whether there is a natural gas leak. Based on controlled leak experiments and diffusion numerical simulations, we develop an atmospheric diffusion model and methane emission inversion algorithm to estimate leak location and flow rate. Post-test data is intelligently managed and empowered, such as leak-based risk assessment and carbon emission quantification. Concentration walls, wind and cloud maps, and third-party damage monitoring are automatically generated.Q6: Is the optical sensor susceptible to damage?

We provide after-sales service and technical support nationwide.We have established a standardized after-sales service process, which is as follows:Receive a customer call or email → Manual registration → Phone or email service → Customer confirmationMaintenance Service(1) Daily maintenanceBefore testing, the detection system must be inspected as a whole to check whether the power supply meets the working requirements, whether the sampling system (gas line) is unobstructed, whether the host wiring plug is loose (connected in reverse), whether the filter needs to be replaced, whether the network is stable, and whether the positioning is accurate.After the test is completed, the wind speed and direction meter, inertial navigation antenna, air intake module, etc. should be disassembled and neatly placed in the trunk of the test vehicle to keep the equipment clean.The external filter of the equipment needs to be checked and kept clean regularly, and is generally replaced every 3 months. When the color of the filter changes significantly, it needs to be replaced in time. The operator can replace and maintain it on site.If the host battery is a rechargeable battery, it should be used and charged according to the product manual.When the instrument is idle, the nickel-hydrogen battery should be fully charged and discharged once a month, and the lithium battery should be removed from the instrument.(2) Precautions for use of the equipmentBefore testing, check whether there are impurities in the 0.01 micron filter in front of the host.Before turning on the analyzer, start the vehicle, turn off the start-stop button, wait for 2 minutes until the current stabilizes, and then turn on the analyzer host power. After satellite positioning is activated and calibration is complete, begin testing.Avoid operating in rainy or snowy weather to prevent moisture from being drawn into the laser cell and contaminating the lens.In winter, the test vehicle must be parked in a garage. If the ambient temperature is below 5°C, the analyzer main unit must be placed indoors.In summer, it is recommended to park the test vehicle in a garage (in a cool, shady location) to avoid prolonged exposure to direct sunlight.In non-rainy or snowy conditions, if the humidity exceeds 85%, a desiccant must be installed on the air intake duct. During operation, if the desiccant color darkens, it must be replaced promptly.Do not drive on roads where water accumulates above the air intake to prevent water from being drawn into the optical cavity.Detours are required on dusty construction roads. If testing is unavoidable on such roads, replace the front 0.01 micron filter immediately after completion. After completing the test, first shut down the analyzer on the tablet, then turn off the main unit power, and finally shut down the vehicle.
