MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641008620 A) filed by Iqnet Systems, Chennai, Tamil Nadu, on Jan. 28, for 'a single-pyrometer multi-zone thermal detection system for hot axle and wheel conditions in railway rolling stock with environmental temperature correction.'
Inventor(s) include Iqnet Systems; and Jeyasekaran.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a wayside thermal condition detection system for railway rolling stock. The system employs a single infrared pyrometer mounted on each side of a railway track, wherein each pyrometer is configured to measure thermal radiation from wheel surface, axle box region, and bogie frame region of a rolling unit during a single pass. Thermal data obtained from the pyrometers is processed to segregate wheel, axle box, and bogie frame temperature components. The bogie frame temperature is used to compensate wheel and axle box temperature measurements for environmental thermal influence. Corrected temperature values are evaluated to detect abnormal thermal conditions and to generate alarms when predefined limits are exceeded. The invention reduces sensor count, minimizes false alarms caused by environmental heating, and improves reliability of axle and wheel condition monitoring in railway wagons and passenger coaches."
