[0056] refer to figure 1 and figure 2 , a highway inspection system based on a track-type inspection robot, including a track 4 laid along the length of the expressway, a track-type inspection robot 3 installed on the track, a communication system and a control station.
[0057] The orbital inspection robot includes a robot controller, GPS / BDS positioning module, environmental data sensor group, voice call module, pan / tilt, and image / video acquisition module installed on the pan / tilt; GPS / BDS positioning module and image / video acquisition The modules are respectively connected with the signal input of the robot controller; the environmental data sensor group includes a noise sensor connected with the signal input of the robot controller; the orbital inspection robot has two noise sensors, and the two noise sensors are about The central axis of the orbital inspection robot is symmetrically installed on the left and right sides of the orbital inspection robot, and the central ...
specific Embodiment approach 2
[0074] Due to the relatively closed space in the tunnel, the noise is more obvious after the traffic accident, and the ambient temperature rises significantly after the fire. This specific implementation makes the following improvements to the highway inspection system based on the track-type inspection robot in Embodiment 1. To better apply to accidents in expressway tunnels:
[0075] The traffic accident identification procedure is carried out in the following steps:
[0076] a1: Analyze the noise data in the environmental data, and judge whether the current environmental noise exceeds the accident noise threshold; if so, go to step a2; if not, repeat step a1:
[0077] a2: Judging the location of the accident according to the noise source and the current location of the track-type inspection robot, and generating a control command to control the track-type inspection robot to move to the traffic accident scene collection location;
[0078] In step a2, locate the noise and c...

Abstract
The invention discloses a highway inspection system and identification method based on a track type inspection robot. The system comprises a track laid along the length direction of a highway, a tracktype inspection robot installed on the track, a GPS / BDS positioning module, a communication system and a control station. A traffic accident identification program is configured in a server of the control station and is used for carrying out identification and positioning on a highway accident based on environmental data during the inspection process. According a highway accident identification method, the highway inspection system and identification method based on a track type inspection robot is connected to a highway monitoring system, so that an emergency command problem after the highway accident occurrence is solved; and after an accident occurs, the worker can arrive at the accident site immediately and transmits the field condition to a highway monitoring center in real time, sothat the monitoring center is able to carry out emergency traffic processing on the accident by a voice broadcast system of the inspection robot conveniently.
Description
technical field [0001] The invention relates to the technical field of expressway monitoring, in particular to an expressway accident identification system based on an intelligent inspection robot, and also relates to an expressway accident identification method. Background technique [0002] my country's transportation construction is entering a period of rapid development. At present, my country has become the country with the most expressways, the most complicated and the fastest developing in the world. With the increase of passenger flow, the transportation facilities gradually develop to the mountainous areas. Due to the limitation of terrain and geological conditions, the mountainous transportation facilities often pass through bridges and expressways. The traffic expressway is a narrow and long building. If a disaster occurs, considering the characteristics of the disaster, it will be difficult to rescue and the consequences will be unpredictable. [0003] With the...
