Autonomous power supply of railway automation devices

The throughput of railway section determines the number of trains traveled through it in a normalized time. On such sections of the railway, trains of various lengths are moving. At the same time, existing design methods provide maximum throughput for a railway section for only one train length. To optimize the throughput of the railway section, it is possible to use auto block system with a variable number of block sections on the railway haul. This leads to additional significant hardware and finance costs, including for providing electric power to additional equipment. To use of a low power, autonomous power supply allows the elimination high-voltage power lines for microprocessor optional equipment of block system with a variable number of block sections. The principle of operation of an autonomous power supply uses the mechanical energy of the moving wheelsets of the train cars, which move on section of the railway. Moving the ferromagnetic material of the wheelsets above the permanent magnet of an autonomous power source converts mechanical energy into electrical energy. The organization of electrical power supply of microprocessor optional equipment of auto block system from converted mechanical energy of wheels reduces capital investment and operating costs for the implementation of innovative transportation management methods.
