| Nowadays, along with production, trade, technical fast development, weighing technology by simple idea again to informationization, integrated development. However, in weighing technology to the development of this trend, the measurement accurate and the fast contradiction always hinders the weighing technological development. Until the 1970s, in technology gradually mature dynamic electronic weighing apparatus development, its effective solution rapidity, accuracy--weighing technology two most important performance index unification question. This regarding the solution project in the real-time weighing question is important, specially regarding overland communication as well as lot item weighing extremely important. Therefore, regarding the dynamic weighing technology research is extremely essential.Dynamic electronic Rail-weightometer is the most common form of the dynamic weighing technology,This article take the Shougang group dynamic electronic Rail-weightometer as the object of study, introduced Shougang group's characteristic in dynamic weighing area,The Shougang group dynamic electronic Rail-weightometer system used the WINDOWS operating system as a platform, its formidable software function was the effective solution rapidity and the accurate unification question foundation; With the software method distinguished the train vehicle type has overcome the hardware distinction law failure rate high weakness; Uses the Automatic Equipment Identification (AEI) technology, solved in the measurement process to copy the number artificially effectively the malpractice, ceased the artificial interpolation measurement data opportunity. The dynamic Rail-weightometer system fully unified Shougang group automation information technology platform (ERP),has achieved data automatic uploading, the statistical report form, the memory, the printing, realized the train not to stop the measurement to meet the true self-service requirements. This paper described the development of the measurement apparatus, load cell principle, the design of dynamic electronic weighing principle and components, signal processing methods, models discriminant logic control system, AEI system applications, as well as the software of dynamic weighing system in Shougang group focused narrative.The Shougang group's dynamic Rail-weightometer system has put the operation since 2004, is at the stable highly effective condition continuously. The measuring accuracy enhances largely, the measurement doubts discusses reduces largely, every year reduces the nonessential loss 10,000,000 Yuan for the enterprise. The fast measurement reduced the commodity dead time, causes the entire commodity measurement, the production management, the railway transportation, the sale and so on each link efficiency big promotion. The self-service measurement reduces the personnel for the enterprise to disburse 800,000 Yuan every year. It has obtained the good economic efficiency and the social efficiency.
