Anti-crossing alarm device for freeway guardrail net

Abstract

The object of the invention is to provide an anti-turn alarm system for high speed highway guardrail net, composed of a detection alarm unit and a monitoring alarm receiving center, etc. The detection alarm unit adopts a vibration detecting sensor, to detect the vibration and other interference information generated by turning the high speed highway guardrail net; acquires vibration signals, amplifying and filtering the signals, and then sending them in a single-chip processing unit, performs acquisition and analysis by ADC in the single-chip; using a fuzzy diagnosis method to compare and analyze the stored database information, filtering out interference signals, in order to accurately detect the warning message generated by turning the high speed highway guardrail net; sending out a warning alarm sound at the scene and sending the warning message to the monitoring alarm receiving center through the cable platform. The invention is applied in the high speed highway guardrail net for preventing the personnel form turning, and plays an active role in protecting the safety operations of highway and reduce the turning of irrelevant personnel, so that the invention not only allows the highway to be more clear, but also can prevent the life-threatening over the turning personnel and reduce the on duty working strength of high-speed highway group posts.
