Embodiment Construction

[0030] Hereinafter, an operation management system for managing vehicles operated at a quarry site or a construction site will be described as a preferred embodiment of the road surface management system of the present invention.

[0031] figure 1 is a schematic diagram showing a schematic configuration of the operation management system according to the first embodiment of the present invention, figure 2 will be figure 1 The structure of the shown dump truck is shown as an example in side view. image 3 It is a block diagram showing the control structure of the operation management system of the first embodiment of the present invention.

[0032] In quarrying or construction sites, e.g. figure 1 As shown, a plurality of excavators 1 for excavation work or loading work, and a plurality of excavators 1 for transporting excavated materials such as stones or sand excavated by the excavators 1 from the loading point where the excavator 1 is located to the unloading point are u...

Abstract

Provided is a road surface management system whereby the state of a road surface likely to cause damage to a dump truck can be sensed, and the position of the road surface can be displayed. When the travel speed of a dump truck (2) detected by a speed sensor (12) is equal to or greater than a preset threshold, a server (4) of an administrative bureau (3) determines that the dump truck (2) is traveling. With each position of the traveling dump truck (2), a determination is made as to whether or not the pressures of suspensions (18L, 18R, 19L, 19R) detected by pressure sensors (20A-20D) are respectively within corresponding set reference ranges. When it is determined that any one pressure of the four suspensions (18L, 18R, 19L, 19R) is outside of the reference range and the remaining three are within the reference ranges, the road surface in the corresponding position of the dump truck (2) is determined to be poor. The position of the road surface determined to be poor is displayed on a display unit (17B) or the like.

Description

technical field [0001] The present invention relates to a road surface management system for managing the road surface state of a travel route of a dump truck at a quarry site or a construction site. Background technique [0002] In a quarrying site or a construction site, many dump trucks are used to transport excavated materials such as stones and sand, and the dump trucks travel between the loading point and the unloading point. Here, when there are irregularities on the road surface of the driving route of the dump truck, it will be affected by excessive fuel consumption, tire wear, etc., and will give the driver an uncomfortable feeling. Therefore, in order to solve such technical problems, a road surface repair system that detects road surface irregularities and repairs them has been proposed (for example, refer to Patent Document 1). [0003] In the road surface repair system described in Patent Document 1, a microwave sensor is provided on the front surface of the d...
