Electric Communications Soundig Device for the Tunneling Machine Control. Development and Research

Issues of the experimental studies the electric communications sounding device built on the basis probes Foerster, for the micro tunneling machine movement control system, have been considered. The hardware and software system model and the experiment conduct methods have been developed. The impact of foreign magnetic field sources on readings three-component sensors has been established in the process study. The considerable existence parasitic noises, conditioned by external magnetic fields and high sensitivity the probes, which will require the use additional filters, has been established. The most informative coil-probe components for various spatial orientation positions of energized probed cable have been identified. The possibility of further detection current cable location and arrangement site by signals the three-component sensors has been established. The experimental studies conducted confirm the feasibility a multisensor sounding device for the micro tunneling machine shield movement control system.
