摘要： The invention concerns a system for sensing train wheels which employs a slotted detector bar. Optical resistive and piezoresistive strain gauges may be coupled to the detector bar as well as enhanced mechanical and electrical components. Optional equipment including an optical sensor, and pulse and frequency modulators improve noise immunity and reduce power consumption.
