Abstract : Operation processes of USSR railroads are currently being automated. Special emphasis is being placed on development of automating the running record and operation control of transportation for the Moscow Railroad. In a period of 24 hrs 8.5 million decimal digits must be stored and processed. Punched cards (80 decimal columns) comprise the storage medium, and the Ural-4 computer processes data. The U-210 punched-card reading unit which serves the Ural-4 computer has a throughput of 300 card/min; daily data storage therefore requires 10 hrs. During data storage the Ural-4 computer does not operate. An analysis of different methods of coupling the input data-storage process with the computer operation shows that none of them is practical for this case. To solve this problem, an independently-controlled intermediate rewriting device was designed and built. The device first translates card decimal code into binary-decimal code and stores single punched-card data in buffer storage. The independent control unit subsequently sends command to stop the computer and then rewrites data at high speed in the computer operation memory unit. The computer is then restarted automatically. The computer idle time is thus reduced by a factor of 26. It was calculated that this fully-automated device saves 50,000-60,000 rubles during a single year of operation solving economical and statistical problems. (Author)
