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.

Claims

1. A travel management device of a transport vehicle at a management center in order to perform management of the transport vehicle having a travelling mechanism and a vessel, the transport vehicle being operated with loaded substance on the vehicle to be reciprocally travelled between a predetermined loading field and unloading field, which comprises:

the transport vehicle having at least a load sensor installed in the transport vehicle to measure weight of loaded substance contained in the vessel, inclination sensor to detect inclination angle of the vehicle and an operation amount sensor to detect travelling speed of the vehicle by the operation of a transmission mechanism, further provided with a wireless communication transmitter for transmitting signals detected by the respective sensor;

the management center being provided with a wireless communication receiver to receive transmitted signal from the wireless communication transmitter, and a signal processing apparatus to create plural number of sensor data on the basis of output signal from respective sensors adapted to be displayed plural number of graphs respectively expressed in a form of chronological pattern; and

further the management center having an image displaying apparatus for displaying on a single screen of plural number of related information on the same time axis.

2. A travel management device of transport vehicle according to claim 1, wherein the image displaying member adapted to show in the same chronological pattern of a difference in height of a travelling rout of the transport vehicle, loaded weight of the vessel and temporal transition of detection data of a step-in quantity of accelerator operation, a travelling rout plural kinds of the related information.
