Problems solved by technology

At present, there is an error of ± 2cm in the detection of lidar on the market. When the tip of the turnout is not tightly attached to the rail, this error is enough to make the judgment result wrong, which will lead to serious consequences of train derailment.

Abstract

The invention discloses a turnout detection system and method. The system comprises a main control module, and an image acquisition module, a laser sensing module and a wireless transmission module which are respectively connected with the main control module; the image acquisition module comprises a camera and a first microprocessor connected with the camera, and the laser sensing module comprises a laser sensor and a second microprocessor connected with the laser sensor; and the first microprocessor and the second microprocessor are respectively connected with the main control module. The method comprises the steps: a camera and a laser sensor collect turnout initial image data and turnout initial point cloud data and respectively transmit the data to a first microprocessor and a second microprocessor; the first microprocessor and the second microprocessor respectively preprocess the received data and transmit the processed data to the local storage device and the main control module; the main control module judges the turnout state according to the received data; and the main control module sends the turnout state judgment result to the control terminal through the wireless transmission module.

Description

technical field [0001] The invention relates to the field of rail transit safety, in particular to a switch detection system and method. Background technique [0002] With the rapid development of urban rail transit, the safety requirements of rail transit are getting higher and higher. The turnout detection system in the prior art mainly relies on the power control system to transmit the state of the turnout. Once the power control system fails, it is easy to cause a subway accident, and the wrong transmission of the state of the turnout may cause the derailment of the subway. [0003] There are two data sources for turnout detection: camera and lidar; use the camera to get a high-resolution picture of the turnout, and use the lidar to detect the precise distance between the turnout and the sensor. At present, there is an error of ± 2cm in the detection of lidar on the market. When the tip of the turnout is not tightly attached to the rail, this error is enough to make the...
