    摘要： The present invention belongs to the technical field of rail traffic and discloses a method and system for monitoring crawling and a close-attaching force of a turnout tongue rail and an external locking apparatus. The method includes: in a case that a tongue rail connecting iron and a connecting iron base are relatively displaced, converting, by a magnetic field inductive sensor, the number of acquired magnetic grids passing through a magnetic grid ruler and a magnetic pickup sequence into a magnetic signal; in a case that a latch hook assembly pushes the connecting iron base, converting, by an optical fiber pin type sensor, a force applied to the optical fiber pin type sensor into an optical fiber signal; processing the magnetic signal to acquire crawling quantities of the tongue rail and the external locking apparatus; and processing the optical fiber signal to acquire a turnout close-attaching force. According to the present invention, a sensing unit is mounted on the external locking apparatus, and it is unnecessary to punch a ballast bed and a rail to mount other instruments and sensing devices. The method is simple and convenient in mounting and simple in construction. According to the present invention, the crawling quantity and the close-attaching force of the tongue rail and the external locking apparatus can be monitored at the same time.

    摘要： ABSTRACT OF THE DISCLOSURE
    The disclosure is directed to a method, system, and apparatus that can be utilized to provide electrical power to an active magnetic ranging (AMR) bottom hole assembly (BHA). The electrical power can be transmitted through a drill string, with an end attached drilling BHA, inserted into a wellbore. The AMR BHA can include a powered isolation sub to create an isolated electrical zone along the drill string. The AMR BHA can create an electrical short along a designated portion of a formation to create a resultant magnetic field to be detected by the AMR BHA or other downhole tools. A drilling wellbore can maintain drilling operations while actively ranging a target well for intercept and other operations. The drilling BHA does not need to be removed from the wellbore to enable the activities of the AMR BHA, and access to the target wellbore is not needed.
