Abstract: An online remote inspect and diagnosis internet system used in the high-speed wire
rolling mill gearbox of large-scale steel factory has been introduced in this article. This system can discern the characteristic signal of their respective malfunctions of these three parts: bearing, gear wheel and shafting in the gear case. Besides this, we have studied the special function and significance of impulse vibration signal in the gear case’s malfunction diagnose. Computer network and remote communication technology are used in the system. RAS (remote accessing service ) system is built by the WINNT4.0 SERVER/WINDOWS2000 SERVER to support the remote accessing. This provide a real and share tool for the diagnose expert and realize the large-scale strange land’s diagnose technology of equipments on the spot. At the same time, the RAS offers a guarantee for the security and credibility of equipments on the spot.
