摘要:
Methods, apparatus, and systems for providing information regarding a locate and/or marking operation to identify a presence or an absence of at least one underground facility within a dig area. At least one notification indicating a status of the locate and/or marking operation is electronically transmitted and/or stored so as to inform at least one party associated with requesting the operation (a “requesting party,” e.g., an excavator, a property owner, a facility owner, a regulatory authority, a damage investigator, etc.) of the status of the operation. In one aspect, a requesting party may designate a preferred format, content, and/or method of receiving notifications regarding the locate and/or marking operation. In another aspect, a computer-generated GUI is provided to facilitate submission of requests, generation of “virtual white line” images to indicate one or more dig areas on a digital image of a work site, and/or selection of notifications and preferences for same. In yet another aspect, a requesting party may provide an acknowledgement of receipt (e.g., a “return receipt”) for one or more received notifications.
摘要:
Marking material is dispensed onto a target surface using a marking device, and one or more images are captured by one or more camera systems attached to the marking device. The image(s) is/are analyzed to determine tracking information indicative of the a motion or an orientation of the marking device. The tracking information is analyzed to determine marking information relating to the dispensed marking material. In one example, the image(s) is/are analyzed to obtain an optical flow plot indicative of a path on the target surface traversed by the marking device. One or more reference plots respectively representing a plurality of reference marking patterns are compared to one or more portions of the optical flow plot to identify at least one reference marking pattern that substantially matches the portion(s) of the optical flow plot.
摘要:
In connection with a locate operation to detect a presence or absence of an underground facility, a magnetic field from an underground facility is detected, and one or more signals also are obtained that are indicative of one or more environmental conditions in an environment in which the underground facility is detected. The signal(s) indicative of the environmental condition(s) are compared to a target value or range of values to determine if an out-of-tolerance condition exists.
摘要:
Managing information relating to a locate and/or marking operation to detect and/or mark a presence or an absence of at least one underground facility. At least one electronic manifest corresponding to the locate and/or marking operation is generated based on first information relating to the locate and/or marking operation. The at least one electronic manifest includes image information documenting performance of the locate and/or the marking operation. At least one limited access file comprising second information relating to the at least one electronic manifest or the image information is generated, and the at least one limited access file and/or information relating to the at least one limited access file is electronically transmitted and/or stored to facilitate selective/limited access to or viewing of the electronic manifest(s).
摘要:
A docking station to dock locating equipment (e.g., marking devices, locate devices, combined locate and marking devices) may be communicatively coupled to and/or equipped with a mobile/portable device (e.g., a mobile phone, personal digital assistant or other portable computing device) that provides processing, electronic storage, electronic display, user interface, communication facilities and/or other functionality (e.g., GPS-enabled functionality) for the docking station. A mobile/portable device may be mechanically and/or electrically coupled to the docking station. The mobile/portable device may provide redundant, shared and/or backup functionality for the docking station to enhance robustness. In one example, the mobile/portable device itself serves as a docking station for the locating equipment.
摘要:
In a locate operation to detect a presence or absence of at least one underground facility using a locate device, an applied signal is transmitted to the at least one underground facility, and/or a magnetic field emitted from the at least one underground facility is detected. Based on the indication of the location provided by a location tracking system, environmental information is obtained regarding at least one environmental condition of an environment in which the locate device is used, and logged into local memory of the locate device.
摘要:
Methods, apparatus and systems for determining the location of a marking device during performance of a marking operation using triangulation are described. The marking device may be of the type used to mark the presence or absence of underground facilities and may include a marking material dispenser to dispense marking material as an indicator. The marking device may include a transmitter which transmits a signal received by a receiving system including two or more receiving devices at separate locations. Triangulation algorithms may then be used to determine the location of the marking device relative to the receiving system.
摘要:
A digital image (e.g., a facility map, an aerial/satellite image, an engineering drawing) is displayed on a display device of a locate receiver used to detect a presence or absence of an underground facility. Image data used to generate the image is selected based on information obtained from a ticket associated with a locate operation for which the locate receiver is used, and geographic information indicative of a location of the locate receiver. Based on a strength of a magnetic field received by an RF antenna of the locate receiver, one or more electronic markings representing a detected presence of the underground facility are overlaid on the displayed digital image.

摘要:
A vehicle-based complex event processing (CEP) engine executes on at least one hardware computer processor in a first vehicle. The CEP engine receives a first input stream onto which vehicle information related to the first vehicle is published, and applies one or more queries to the first input stream to assess if a vehicle-related event has occurred. If it is determined that the vehicle-related event has occurred, the CEP engine publishes an indication of occurrence of the vehicle-related event on an output stream of the vehicle-based CEP engine, and transmits the indication of occurrence of the vehicle-related event from the first vehicle.
