Problems solved by technology

But at present, there is a lack of an effective way to transmit the accident signal to every driver entering the tunnel in a timely manner. The traditional method is generally that after a vehicle accident or breakdown occurs in the tunnel, the vehicle in the accident turns on the fault light, calls for help, and waits for the traffic police to deal with it. , but because the light in the tunnel is relatively dim, in the process of waiting for the traffic police, when subsequent vehicles enter the tunnel, especially when vehicles driving on the expressway enter the tunnel, they often cannot see the fault light signal of the faulty vehicle in time, which makes the driver Failure to do a good job of deceleration and avoidance in time will lead to the occurrence of secondary accidents and bring serious losses to people's lives and property

Abstract

The invention discloses a wireless alarm system for preventing secondary accidents of a freeway tunnel group, which comprises alarm base stations, a signal repeater, a scene alarm assembly, a remote controller and a monitoring center, wherein the alarm base stations are distributed in a channel and used for starting an alarm signal when an accident is generated; the scene alarm assembly is arranged at the entrance of the channel; the alarm signal of the alarm base stations is transmitted among the alarm base stations in the channel by a wireless network; the accident alarm signal of the alarmbase stations is finally transmitted to the remote controller, and the scene alarm assembly is driven by the remote controller to remind the following vehicle to slow down or avoid entering the channel in an acousto-optic picture way; the remote controller is communicated with the monitoring center by a GSM / GPRS network, and the monitoring center carries out remote monitoring on scene equipment and an alarm state by the remote controller. The invention can effectively prevent the secondary accidents of a freeway tunnel group.

Description

technical field [0001] The invention relates to an expressway alarm system, in particular to a Zigbee technology-based wireless alarm system for secondary accident prevention in expressway tunnel groups. Background technique [0002] Tunnel secondary accidents refer to rear-end collisions, collisions and other accidents caused by vehicles entering the tunnel at a high speed without timely knowing the situation in the tunnel when the vehicle has an accident or breakdown in the parking lot. In order to reduce the occurrence of secondary accidents in tunnels, it is very important to transmit and indicate accident and fault signals to every driver entering the tunnel in time. But at present, there is a lack of an effective way to transmit the accident signal to every driver entering the tunnel in a timely manner. The traditional method is generally that after a vehicle accident or breakdown occurs in the tunnel, the vehicle in the accident turns on the fault light, calls for hel...
