摘要： Systems and methods are described for detecting a leak based upon home telematics data. The method may include: (1) receiving home telematics data from one or more sensors associated with one or more pipes (or piping systems) in a structure, wherein the home telematics data is indicative of the frequency with which the one or more pipes are being used; (2) determining, using a trained machine learning algorithm, pipe activity associated with the one or more pipes is occurring at an irregular frequency; (3) determining, based upon at least the determination that the pipe activity associated with the one or more pipes is occurring at the irregular frequency, that the one or more pipes are leaking; and (4) transmitting an indication to a user associated with the home that the one or more pipes are leaking.

摘要： A method for determining a leak in a line for fluid media can include providing at least one noise and/or frequency logger comprising a sensor, and a computing unit, attaching the noise and/or frequency logger to the line or to fittings thereof, measuring noise on the line via the sensor and determining a noise level by means of a frequency analysis of the noise level. The determined frequency spectrum may be divided into two or more frequency bands, and a threshold value may be determined for each frequency band. A threshold value can be determined for each frequency band, and compared the measured noise to determined if one or more threshold values are being exceeded. A leak in the line can be thus be determined and/or analyzed by means of the computing unit.

摘要： One of the biggest challenges faced by oil and gas companies is to monitor such long pipelines for leak events and generate false leak event alarms during routine pipe maintenance. A data associated with a first sensing unit is processed to obtain an instant timing information (T0) of a leak event in a conduit at a test environment. A data associated with a second sensing unit is processed to obtain a transient signal associated with the leak event at a specific band. An accelerometer data is filtered to obtain a band passed filtered accelerometer signal (Accelbpf). The Accelbpf is truncated in a time domain from the T0 to a duration Td of the leak event to obtain a temporal template signal (Acceltemplate). A leak event of a real-time conduit is dynamically detected at a physical environment based on Acceltemplate when a cross-correlation value is greater than a threshold value (∝).

摘要： A consumption meter, e.g. a water or heat meter, for measuring a flow rate of a fluid supplied in a flow tube. First and second ultrasonic transducers are arranged at the flow tube for transmitting and receiving ultrasonic signals transmitted through the fluid and operated by a flow measurement sub-circuit for generating a signal indicative of the flow rate of the fluid. A noise measurement sub-circuit operates a sensor arranged at the flow tube for detection of acoustic signals of the flow tube, and being arranged to generate a signal indicative of a noise level of the flow tube accordingly. This sensor may comprise a separate transducer, or the sensor may be constituted by one or both of the first and second ultrasonic transducers. The consumption meter may communicate data representative of the noise level via a communication module along with data consumed amount of water, heat etc. Such consumer noise level measurement at the consumer site allows collection of noise level data to assist in locating fluid leakages in a fluid supply pipe system.

摘要： A method for detecting leaks in a pipe in a system including a processor and at least one sensor installed on the pipe, may include generating, by the processor, a plurality of signals based on measurements from the at least one sensor. The method may include calculating, by the processor, at least two cross correlations from the plurality of signals. Each cross correlation may correspond to two of the plurality of signals. The method may include calculating, by the processor, a signal to noise ratio (SNR) of each of the at least two cross correlations. The method may include selecting, by the processor, a cross correlation that has a greatest SNR among the at least two cross correlations. The method may include detecting a leak in the pipe based on the selected cross correlation.

摘要： A leak detection sensor may be capable of dynamically adjusting a sampling time for acoustic data based on monitored fluid flow. The leak detection sensor monitors leak detection information associated with a fluid in a fluid transporting medium over a predetermined time interval, where the leak detection information comprises flow and pressure of the fluid in the fluid transporting medium, and processing the leak detection data monitored at the sampling time in the predetermined time interval, where the sampling time is determined based at least in part on the monitored flow of the fluid.

摘要： Methods, systems, and techniques for simulating an event. Simulated event data comprising a simulated event, and authentic raw data, are both obtained. The simulated event data and the authentic raw data are blended to form blended data that comprises the simulated event. The blended data may be fed into an event detection system, such as a pipeline leak detection system, for testing purposes.

摘要： A method for detecting a deterioration defect of a structural part using a structural unit includes: defining a first base structural unit and obtaining N first base modal parameters of the first base structural unit; detecting a respective one of M first subject structural units of a subject structural part by each of M first sensors to obtain N first actual modal parameters of each of the M first subject structural units; calculating N first subject modal parameters of each of the M first subject structural units according to the N first actual modal parameters of each of the M first subject structural units and M*N first predetermined ratios; and comparing the N first subject modal parameters of each of the M first subject structural units to the N first base modal parameters to determine whether each of the M first subject structural units has a deterioration defect.
