To solve the problems of poor branching and red light strip in the track circuit of Daqin Railway, a cable transmission scheme combining axle counting technology and track circuit is proposed. The potential application of axle counting technology in solving track circuit problems was analyzed, the overall architecture of the system was designed, key modules are identified, and the system workflow was clarified; Then the key components were designed and corresponding renovation plans were proposed based on the on-site situation; Finally, overall testing on the system was conducted to verify its stability and reliability, and test results that meet expectations were obtained. This plan can provide technical reference for related circuits with issues such as poor branching and red light bands.
