Study on Collision early Alert System of Large-Scale Mechanical Equipment for Hydropower Station Construction

Abstract

Collision between mechanical equipment during the process of hydropower station construction frequently happens, and always causes great damage. Consequently, a set of collision early alert system, which employs GPS positioning technology, wireless microwave communication technology and virtual instrument technology, was developed. Functions of this system include dynamic picture display of the field model, sound light anti-collision alert of the mechanical equipment, remote monitoring of the running equipment, and fault diagnosis of the GPS equipment. With this system, the collision possibility among the various equipment in the process of operation was reduced. The paper mainly introduces the system’s hardware design, software design, collision calculation and so on. Practicability, efficiency and reliability of this system have been proved through experiment and practice in LONGKAIKOU hydropower station.
