摘要： Systems and methods for monitoring underwater structures are provided. First and second sets of point cloud data that are obtained at different times are compared to determine whether the location of the underwater structure has changed. For detecting vibration, a series of range measurements taken along a line intersecting the underwater structure are compared to one another to determine an amplitude and frequency of any vibration present in the underwater structure. For detecting temperature, the ratio of different components of return signals obtained from a point in the water surrounding the underwater structure is measured to derive the temperature of the water. Leak detection can be performed by scanning areas around the underwater structure. Monitoring systems can include a primary receiver for range measurements, and first and second temperature channel receivers for temperature measurements.

摘要： The present disclosure relates to a device and a method for pipeline leakage detection. The device for pipeline leakage detection includes a metal powder storage box, a plurality of ribs, and a signal collection and processing device. The metal powder storage box is ring-shaped and made of insulating material, which is configured to be sleeved on a pipeline. Metal powder is stored inside of the metal powder storage box, and inner and outer peripheral walls of the metal powder storage box are of mesh structure, which allows the metal powder to be ejected from the metal powder storage box under the push of leakage fluid of the pipeline. The plurality of ribs are made of insulating material, which are distributed evenly along an outer peripheral wall of the metal powder storage box, and fixed on the metal powder storage box respectively, and a plurality of coils arranged in a layer are configured inside the plurality of ribs. The signal collection and processing device is connected to each coil for collecting and monitoring electromagnetic signal of each coil and obtaining leakage parameters based on the abnormal signal when an abnormal signal occurs. The present disclosure can well detect whether the pipeline leaks and obtain the leakage parameters efficiently, portably, and accurately in the case of leakage.

The sensor may connect to a control unit, preferably with operating hardware that can process signals. This arrangement may secure to structure of the valve. In one implementation, the sensor can connect to connections that exist on a circuit board. This feature permits upgrades to devices, including those in assembly or those in the field, with minimal impact to design or performance.

摘要： A system for detecting water damage to a structure may include a plurality of energy-harvesting sensors on or within the structure, each sensor being configured to (i) generate sensor data indicative of one or more characteristics of air, construction materials, and/or water within the structure and (ii) generate power for operating the sensor responsively to an external stimulus other than an electrical power source. One or more processors of the system receive sensor data generated by the energy-harvesting sensors, detecting water damage to the structure by analyzing at least the sensor data, and cause an indication of the detected water damage to be presented to a user.

摘要： A gas detector for revealing a target gas includes an image capturing unit with multiple optical channels, an image processing unit and a calculation unit. The image processing unit is adapted for deducing a value of a radiation transmission coefficient which relates to an analysis spectral band, and which is attributable to a quantity of the target gas present in a part of the field-of-view. Preferably multiple analysis bands are used in parallel. The calculation unit is adapted for deducing an evaluation of the quantity of the target gas based on the value of the radiation transmission coefficient which relates to each analysis band. Such a gas detector may have small dimensions, be easily transportable, including on board a drone, and can provide evaluation results for the quantity of the target gas in real-time or nearly real-time.

摘要： Methods, apparatuses, and computer program products for fugitive gas quantification are provided. For example, a computer-implemented method may include obtaining gas column density maps associated with one or more gas leak tests, each with an associated distance and leak rate; if the density maps do not meet a predefined quality threshold, filtering the density maps to remove any that do not meet predefined quality metrics and generating a leak rate predictive model based on providing some or all of any remaining density maps that meet the predefined quality metrics, associated distances from the gas leak imaging device to the gas leak tests, and associated leak rates to an artificial intelligence algorithm; and if the density maps meet the predefined quality threshold, generating a leak rate predictive model based on providing some or all of the density maps, associated distances, and associated leak rates to the artificial intelligence algorithm.
