Locate apparatus configured to detect out-of-tolerance conditions in connection with underground facility locate operations, and associated methods and systems
Abstract:
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.
Abstract(Chinese):

关于检测地下设施的存在或不存在的定位操作，检测到来自地下设施的磁场，并且还获得指示在环境中的一个或多个环境条件的一个或多个信号，其中 检测到地下设施。 将指示环境条件的信号与目标值或值的范围进行比较，以确定是否存在超出容限的条件。
