MUMBAI, India, Sept. 5 -- Intellectual Property India has published a patent application (202047051640 A) filed by Crrc Nanjing Puzhen Co. Ltd., Jiangsu, China, on Nov. 27, 2020, for 'rail transit vehicle magnetic rail braking logic control system.'
Inventor(s) include Sun, Jiani; Zhang, Qian; Mao, Xun; Song, Dejian; Xiao, Fei; Xue, Hongquan; Zhang, Hongfei; and Yu, Kai.
The application for the patent was published on Sept. 5, under issue no. 36/2025.
According to the abstract released by the Intellectual Property India: "A rail transit vehicle magnetic rail braking logic control system, applied to a high-suspension magnetic rail braking apparatus, and comprising a magnetic rail braking control circuit, a magnetic rail braking power supply execution circuit, and a magnetic rail braking state monitoring and feedback circuit. According to the system, automatic control can be set by means of a vehicle speed signal, and manual control can be achieved by artificially pressing a button, so as to achieve time-sharing control of a magnetic rail braking execution apparatus and an electromagnet. After five minutes of excitation of the electromagnet, power is automatically cut off to prevent damaging the electromagnet since the electromagnet works for a long time. The magnetic rail braking power supply execution circuit can achieve functions of motion control of the magnetic rail braking execution apparatus, excitation control of the electromagnet, and electromagnet coil outage reverse DC800V impulse voltage protection. The rail transit vehicle magnetic rail braking logic control system can be promoted to all medium and high-speed urban rail vehicles according to specific scene application requirements, and can safely and reliably control a magnetic rail braking system."
The patent application was internationally filed on Dec. 05, 2019, under International application No.PCT/CN2019/123203.
