    摘要: The embodiments of the present disclosure provide a method for safety management of a compressor in a smart gas pipeline network and an Internet of Things system thereof. The method is implemented based on a smart gas safety management platform of an Internet of Things system for safety management of a compressor in a smart gas pipeline network. The method comprises: obtaining sound data and a target vibration feature of a gas compressor, and determining a target sound feature based on the sound data; obtaining gas data and device data, and determining a standard sound feature and a standard vibration feature based on the gas data and the device data; and predicting whether there is a safety hazard in the gas compressor based on the target vibration feature and the standard vibration feature, or based on the target sound feature and the standard sound feature.

    摘要: A system for forecasting leaks in a fluid-delivery pipeline network. The system identifies a subsystem in the pipeline network that comprises a plurality of topologically connected stations. The system accesses historical temporal sensor measurements of a plurality of variables of the stations that are directly connected and generates a temporal causal dependency model for a first control variable at the first station in the subsystem, based on the plurality of time series of sensor measurements of a second variable of the first station, and temporal delay characteristics of the plurality of time series of sensor measurements of the second variable at the stations directly connected to the first station. The system automatically calculates a normal operating value of the first control variable at the first station and the deviations between actual measured values and the normal operating value and determines a threshold deviation that indicates a leak event.

    摘要: A geothermal heat containment barrier operable to be manipulated through an opening of a vault by at least partially folding the geothermal heat containment barrier, and positioned substantially horizontally against walls of the vault to reduce heat transfer through the barrier is provided. The barrier includes a central insulating core, a flexible outer frame, and an outer sealing trim. The central insulating core includes top and bottom outer surfaces and a perimeter edge. The central insulating core includes and/or contains an insulating material. The flexible outer frame has a shape memory and includes at least one flexible component having ends together such that the flexible outer frame is continuous and closed. The outer sealing trim is attached to the top and bottom outer surfaces and wraps around the perimeter edge of the central insulating core. The outer sealing trim is operable to press against the wall of the vault.

    摘要: Methods and systems for modelling pipeline construction, include or implement steps of (a) obtaining ranging data of a pipeline construction location including a pipe; (b) processing the ranging data to produce a spatially organized point cloud; and (c) processing the point cloud to identify at least one geometric feature comprising a point or a two-dimensional feature representative of a pipe centreline, and associating the at least one geometric feature with the pipeline construction location. The ranging data may be data obtained from a lidar device. The pipeline construction may be underground construction, where pipe is laid in a ditch. Relevant information, such as depth-of-cover may be calculated from identified geometric features. Relevant information may be determined in real-time or near-real-time and displayed, communicated or recorded as desired.

    摘要: A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline includes an upstream portion of the pipeline supplying a flow of fluid material, a crossing portion of the pipeline receiving the flow of fluid material from the upstream portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline, the downstream portion, a pipeline pressure activated valve selectively capable of blocking the flow of fluid material from entering the crossing portion based upon a change in pressure within the crossing portion, and a fluid capacitor connected to the upstream portion configured to filter out a pressure spike in the upstream portion associated with the valve blocking the flow of fluid material.

    摘要: A gas supply line control system and method for preventing flow reversal due to an upstream pressure drop in a natural gas supply line, the system and method include setting a threshold low pressure for the upstream gas flow, continually sensing the upstream pressure, activating a trigger valve when the upstream pressure falls below the threshold low pressure, and closing a control valve in response to the trigger valve to prevent reversal of flow in the gas supply line.
