Rail Transit Bow Net Solution

Real-time online monitoring system for biomimetic binocular arch net

The first domestic developer of biomimetic binocular multi-sensor technology integrated monitoring equipment

Biomimetic binocular vision technology simulates human visual mechanisms and studies intelligent vision systems that include information collection, transmission, processing, understanding, and storage. Online self-calibration technology based on motion measurement can perform real-time 3D reconstruction of scenes in driving areas. Combined with a deep learning network framework and a multinetwork fusion mechanism, Realize end-to-end real-time detection and tracking of pantograph and catenary targets, as well as disparity stereo matching to calculate the geometric parameters of the pantograph and catenary.

The biomimetic binocular bow net real-time online monitoring system integrates multiple sensing technologies such as ultraviolet, infrared, laser, acceleration, inertial navigation, etc. It can achieve functional detection of bow net status, -ghttask integrity of bow net structure, geometric parameters of contact net, arc burning, temperature, bow head vibration, contact line wear, etc. The system has vibration compensation, positioning functions, and unified timing functions to ensure the accuracy of detection; Highly integrated monitoring equipment has the characteristics of small size, lightweight, low power consumption, easy installation, and real-time, comprehensive, expandable, and interchangeable; It can meet harsh usage environments such as vehicle vibration, high temperature, and high pressure, and is very suitable for outdoor testing tasks.
