Photovoltaic Technology and Electricity Saving Strategies for Fixed-Velocity-Measuring System

This paper designed an implement scheme of the alnic automatic measuring system for rail type vehicles. The system can read information of rail type vehicles by adopting four alnics, through the PLC to achieve the vehicles’s direction measuring and vehicles counting and axle counting and velocity measuring. In order to improve system reliability, comprehensive application of the anti-jamming alnic, software fault-tolerant variety of anti-jamming measure. By setting the calibration alnic, the system effectively overcome the interference of a variety of human factors. By cleverly setting registers N1N1N3 and in accordance with the principle of FIFO N1N2N3 pass assignment, software design is simplified. This system is widely used in modern logistics production and transportation management process of large and medium-sized enterprises involving the train transportation embedded in information management control system or warehouse management control system with high precision, stable and reliable performance, the low product cost.
