Technical Problem
[0008]本实用新型的目的在于解决现有技术中工程机械在铁路施工作业中限速手段缺失，通信手段不稳定导致安全风险较高的技术问题，提供一种工程机械限速报警装置
Benefits of technology
本实用新型公开了一种工程机械限速报警装置，通过速度采集单元实时获取工程机械的运行速度，发动机控制单元在接收到速度信息后，能够主动判断是否超过预设的安全限值。一旦判定超速，发动机控制单元会立即发出控制指令给油门控制执行器，直接干预发动机的供油量，强制降低发动机转速和输出功率，从而主动、强制性地将机械运行速度限制在安全范围内，有效预防因超速引发的倾翻、失控等安全事故。通过主动限制速度，显著降低了工程机械（尤其是挖掘机、装载机、起重机等重心高、工况复杂的设备）在行驶、转向或作业过程中因速度过快导致侧翻、失稳、制动距离过长等事故的风险。
