Problems solved by technology

But in theory, as long as there are no unlimited rainfall monitoring stations installed on the entire line, then this kind of early warning technology solution based on rainfall monitoring stations along the railway will inevitably exist in some railway areas without rainfall monitoring stations Early warning blind spot

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] Such as figure 1 As shown, a real-time intelligent measurement method for railway heavy rainfall UAV, including the following steps:

[0042] Step 1: Collect rainfall observation information along the railway line, select the railway track rainstorm risk zone that exceeds the historical annual rainfall, divide the railway track rainstorm risk zone at equal intervals, and configure two sets of UAVs for each railway track rainstorm risk zone unit Devices, respectively UAV rainfall measurement device and UAV image acquisition device;

[0043] The unmanned aerial vehicle rainfall measuring device comprises a flying device and a microwave rain gauge loaded on the flying device, a Kinect sensor, a thermometer, a hygrometer, a wireless communication module and a train speed measuring device, and the unmanned aerial vehicle image transmission device inc...

Abstract

The invention discloses a method and system for real-time intelligent measurement of railway heavy rainfall by unmanned aerial vehicle. The method realizes active rainfall measurement for the local moving environment of the controlled train by introducing an unmanned aerial vehicle rainfall measurement device, and utilizes the unmanned aerial vehicle rainfall The measuring device carries a microwave rain gauge, a train speed measuring device, a thermometer, and a hygrometer to measure the temperature, humidity, rainfall, and speed of the train, and calculates the safe speed limit of the train under the current rainfall condition in real time, avoiding from the technical plan The "monitoring blind spot" of rainfall; according to the collected rainfall, train speed and line slope information, the line-of-sight distance of the train is calculated in real time, and the mobility of the UAV device is used to monitor the line-of-sight of the train in real time using the UAV image transmission device. The image of the line is sent back to the on-board display device of the train, which expands the train driver's sight distance under heavy rainfall conditions and improves the operational safety of high-speed trains in heavy rainfall environments.

Description

technical field [0001] The invention belongs to the field of railway track detection, and in particular relates to a method and system for real-time intelligent measurement of heavy rainfall in railways by an unmanned aerial vehicle. Background technique [0002] If the section along the railway suffers from severe debris flow disasters, it will endanger the traffic safety. Under the condition of heavy rainfall, the sight distance of the train driver is seriously reduced, and it is difficult to find the dangerous situation ahead in the heavy rain. At the same time, mudslides and landslides caused by heavy rains pose serious hazards to the railway subgrade. The accident with the heaviest passenger casualties in the history of China's railways - the train crash on the Chengdu-Kunming Railway. According to Japan’s Shinkansen regulations, trains are put on alert when precipitation exceeds 25mm in 1 hour, and trains run at a speed limit of 170km / h when precipitation reaches 40-...
