Abstract

Aiming at the alarm system of electrical construction machinery, which is mostly developed based on the principle of near electric alarm in the current market, a more excellent safety system is developed: research on the safety alarm distribution and control system of electric construction machinery based on edge computing technology. The X-band-based linear frequency modulation continuous wave (LFMCW) ranging radar is selected as the basic detection method. The system consists of the front-end monitoring device, signal processing and display, and acoustic and optical alarm equipment. To carry more new functions in the future, the front-end monitoring device adopts edge computing technology to overcome the shortcomings of centralized cloud computing. In the application test, the system has high detection accuracy and high practical use value, which can improve the safety of field operations, reduce the burden of safety supervision, and has good promotion value.
