The invention provides a collision safety monitoring system based on a vehicle-mounted Ethernet, which comprises the following steps that: in a safety monitoring mode, a monitor detects the surrounding environment of a vehicle body in real time, when the distance between a detected object and the vehicle body is smaller than a preset first threshold value, the monitor sends early warning information to wake up an MCU, the MCU wakes up an SoC, and the SoC starts a vehicle surrounding image acquisition module to obtain a plurality of paths of images; when the collision is detected, storing images of a preset second duration before and after the collision to a preset path to form collision data; the MCU detects the electric quantity of the vehicle body in real time, and if the electric quantity of the vehicle body is lower than the preset electric quantity, the MCU conducts power-off operation on the SoC and does not wake up the SoC. And online monitoring is realized through the safety monitoring system, and the system is in a dormant state without surrounding objects, so that energy is saved. And when collision occurs, the camera is awakened in time for shooting, so that parking safety and accident tracing under the unattended condition are realized, and the problem of difficulty in vehicle loss tracing caused by small capacitance and incapability of long-time standby of a fuel truck is solved.

    本发明提供一种基于车载以太网的碰撞安全监控系统,包括:在安全监控模式下,监视器实时检测车身四周环境,当检测到的物体离车身的距离小于预设第一阈值时,监视器发送预警信息唤醒MCU,MCU唤醒SoC,SoC启动环车图像采集模块获取多路图像;当检测到碰撞发生后,将碰撞发生前后预设第二时长的图像保存至预设路径,形成碰撞数据;MCU实时检车车身电量,若车身电量低于预设电量时,MCU对SoC进行下电操作并不在唤醒SoC。通过安全监控系统实现在线监控,并且周围无物体系统处于休眠状态,节省能源。当出现碰撞及时唤醒进行拍摄,实现无人看管情况下的停车安全及事故追溯,解决油车电容量小,无法长时间待机导致的车辆损失追溯难问题。
