Abstract: Provided is a data processing assistant system, a data processing assistant method, and a data processing assistant program. The data processing assistant system includes: a processing record accumulation unit that accumulates processing records in which one or more pieces of data, data processing performed using the data, and a processing result of the data processing are associated with each other; a correspondence relation data creation unit that creates, based on the processing records, correspondence relation data indicative of a correspondence relation among a data type indicating a type of the data, a question to be solved by the data processing, and the processing result; and a processing information presentation unit that presents, upon receiving designation of the data type and the question, information related to appropriate data processing based on the correspondence relation data.

Abstract: Operation of self-propelled mining equipment in the field can be accurately recognized at a remote position of the equipment. A management center for controlling a dump truck receives signal from sensors in order to show detection data for the working status of the operation instruments and warning indication data based upon the detection data. The warning indication data and the detection data for the working status of the operation instruments are displayed on the same display. Alternatively, in place of the detection data for working status of the operation instruments, related information from a data base concerning the record of maintenance previously conducted may be displayed, or a graph of the detection data for the working status of an operation instrument of another dump truck which is operating in the same working field may be displayed.

Abstract: Travel management is adapted to perform of transport vehicle at working areas which are widely different in geographical conditions to ensure operation in a facilitated manner with high efficiency of exhaust gas and at high running efficiency. A signal processor (32) of a management center (30) is processed signals transmitted from sensors provided in a dump truck (2) to create, then on the basis thereof a display (33) is shown graphs respectively expressed in a form of temporal transition on chronological pattern for load of the dump truck (2), inclination on travelling rout of the dump truck 2 and step-in quantity of an accelerator pedal by the operator, thereby ensuring high efficiency of exhaust gas and at high running efficiency by properly operating the acceleration pedal on the basis of comprehensive judgment taking in consideration of the load weight of the dump truck (2) and travelling rout.
