According to the tunnel traffic information wireless publishing method based on frequency modulation data broadcasting, wireless publishing of tunnel traffic information is achieved, tunnel managementpersonnel publish related traffic information into a tunnel remotely and wirelessly in time, wired communication line constraints are eliminated, tunnel traffic information publishing reliability andeffectiveness are improved, the transformation work amount is small, and operation is easy and convenient. The method comprises the following steps: (1) serving as a standby mode for traffic information release; (2) judging whether the mobile display device is a mobile display device, if so, executing the step (6), otherwise, executing the step (3); (3) judging whether wired communication interruption is caused by an emergency reason or not, if so, executing the step (6), and otherwise, executing the step (4); (4) judging whether wired communication is interrupted due to maintenance, if so, executing the step (6), otherwise, executing the step (5); (5) as a standby link, going to the step (1); (6) the traffic information display device receiving the frequency modulation data broadcast information; and (7) sending the tunnel traffic information through a frequency modulation broadcast transmitter.
基于调频数据广播的隧道交通信息无线发布方法,实现隧道交通信息的无线发布,隧道管理人员及时向隧道内远程无线发布有关交通信息,摆脱有线通信线路约束,提高隧道交通信息发布可靠性和有效性,改造工程量小、操作简便。包括:(1)作为交通信息发布的备用方式待命;(2)判断是否为可移动显示设备,是执行步骤(6),否则执行步骤(3);(3)判断是否因紧急原因导致有线通信中断,是执行步骤(6),否则执行步骤(4);(4)判断是否因检修中断有线通信,是执行步骤(6),否则执行步骤(5);(5)作为备用链路待命,转至步骤(1);(6)交通信息显示设备接收调频数据广播信息;(7)通过调频广播发射机发送隧道交通信息。
