货车情报对铁路行车调度具有十分重要意义。它是全面、迅速提高运输组织水平和经济效益的关键。目前我国系采用人工方法收集此类情报,造成人力和物力上的浪费,因此迫切需要建立用电子计算机查询铁路货车情报的系统。本文介绍一种在PDP-11计算机上调试所得的货车情报查询软件系统,并讨论其功能、结构、情报流程及模型,重点论述产生三个子系统的方法,即货车情报收集的处理、货车动态信息库的管理和货车查询服务系统。
Truck information is of great significance to railway traffic regulation. It is the key to a comprehensive and prompt improvement of the transport organization’s level and economic efficiency. At present, China collects such intelligence by using manual methods, resulting in human and material waste. Therefore, there is an urgent need to establish a system for using computers to check the intelligence of railway wagons. This paper introduces a software system of truck information inquiry which is debugged on PDP-11 computer and discusses its function, structure, intelligence flow and model, and focuses on the method of producing three subsystems, that is, the processing of information collection of trucks, the dynamic information of trucks Library management and truck inquiry service system.
