摘要：【中文】本发明公开了一种三危驾驶行为监测与报警系统，包括三危驾驶监测器、组合仪表、T‑BOX及T‑BOX网络后台，所述三危驾驶监测器分别通过CAN总线连接组合仪表、T‑BOX，所述T‑BOX通过无线网络连接T‑BOX网络后台。所述三危驾驶监测器安装于车身前部位置，包括三轴加速度和计算单元，计算单元根据三轴加速度计监测的各方向的加速度大小，综合判断司机危险驾驶行为及危险等级。本发明的三危驾驶行为监测与报警系统，监测器内部集成的三轴加速度计，具有低功耗和高分辨率性能，灵敏度可达49mg，极大的提高了驾驶行为监测的精度与准确率；将报警数据传输至后台并形成分析报表，便于公交公司掌握公交司机驾驶情况，做出针对性管控。 【EN】The invention discloses a triple-risk driving behavior monitoring and alarming system which comprises a triple-risk driving monitor, a combination instrument, a T-BOX and a T-BOX network background, wherein the triple-risk driving monitor is respectively connected with the combination instrument and the T-BOX through CAN buses, and the T-BOX is connected with the T-BOX network background through a wireless network. The three-danger driving monitor is arranged at the front position of the vehicle body and comprises a three-axis acceleration and a calculation unit, and the calculation unit comprehensively judges dangerous driving behaviors and dangerous grades of a driver according to the acceleration in each direction monitored by a three-axis accelerometer. According to the three-risk driving behavior monitoring and alarming system, the three-axis accelerometer integrated in the monitor has low power consumption and high resolution performance, the sensitivity can reach 49mg, and the precision and accuracy of driving behavior monitoring are greatly improved; alarm data are transmitted to the background and analysis reports are formed, so that a public transport company can master the driving condition of a bus driver conveniently and make targeted management and control.
