The invention discloses an expressway active road occupation early warning system based on a wireless network, belongs to the field of optics, and aims to solve the problem that an existing traffic cone is insufficient in active early warning capability. The system comprises a sentry node and an alarm node, the alarm node is arranged on a construction road section, and the sentry node is arranged on a normal traffic road section behind the construction road section and is D away from the alarm node; the sentry nodes are arranged on the two sides of a road of a normal traffic road section and used for detecting vehicles on the road surface, and when it is detected that a vehicle enters, the sentry nodes send vehicle entering signals to the alarm node in a wireless communication mode; the alarm node is used for receiving the vehicle driving-in signal sent by the sentry node, giving an on-site alarm to an on-site constructor and reminding the on-site constructor that a vehicle is driven in behind; and the alarm node is also used for uploading the position data of the current construction road section to the map server so as to give an early warning to a driver through the map server and mark the position information and the speed limit information of the construction road section.

    基于无线网络的高速公路主动占道预警系统,属于光学领域,本发明为解决现有交通锥主动预警能力不足的问题。本发明包括哨兵节点和报警节点,报警节点设置于施工路段,哨兵节点设置于施工路段后方的正常通行路段且与报警节点相距D;所述哨兵节点设置于正常通行路段的道路两侧,对路面上车辆进行检测,当检测到有车辆驶入时,哨兵节点通过无线通信方式将车辆驶入信号发送至报警节点;所述报警节点,用于接收哨兵节点发送的车辆驶入信号,对现场施工人员进行现场报警,提醒现场施工人员后方有车辆驶入;所述报警节点,还用于将当前施工路段的位置数据上传至地图服务器,以通过地图服务器对驾驶员进行预警,标示施工路段位置信息和限速信息。
