A fleet management server is connected to onboard terminal equipments mounted on plural haulage vehicles. The server includes an operation mode determination unit and operation mode switching unit. The determination unit determines whether or not an operation mode, in which segment setting processing is performed to set travel-permitted segments for the vehicles, respectively, needs switching between a bidirectional mode and a push mode. In the bidirectional mode, the processing is performed to send response information upon reception of request information from each onboard terminal equipment. In the push mode, a travel-permitted segment setting unit, without reception of such request information, performs the processing for one of the vehicles to set a new travel-permitted segment, and produces and transmits travel permission information indicating the new travel-permitted segment. The switching unit performs switching processing of the operation mode according to the results of the determination. |

1. A fleet management server connected, via a wireless communication network, to onboard terminal equipment mounted, respectively, on a plurality of haulage vehicles, which travel along a predetermined travel route in a mine, to perform fleet management of the plurality of haulage vehicles, comprising:
a control system connected to a wireless communication system configured to perform wireless communications with the individual onboard terminal equipment, and including a central processing unit coupled to a memory; and a storage device, coupled to the central processing unit, configured to store map information of the travel route, wherein the memory stores instructions, that when executed by the central processing unit, cause the central processing unit to: receive position information of a subject vehicle of the plurality of haulage vehicles and position information of an immediately preceding vehicle, which is on the travel route immediately ahead of the subject vehicle, transmitted from the wireless communication system, and read the map information from the map information storage device, set a front boundary point on the travel route at a position that is behind the immediately preceding vehicle, and a rear boundary point on the travel route that is closer to the subject vehicle than a point at a predetermined margin distance from a following vehicle on the travel route, which is a distance needed for the following vehicle to stop, perform segment setting processing for setting segments on the travel route from the rear boundary point to the front boundary point as travel-permitted segments, in which only the subject vehicle is permitted to travel, receive travel state information which identifies whether the subject vehicle is traveling or at stop from the wireless communication system to determine whether or not the subject vehicle is travelling or at stop, when the control system determines that the subject vehicle is traveling, the control system operates in a bidirectional mode in which, in response to the received request information transmitted from the subject vehicle that indicates a request for setting of the travel-permitted segment, performs the segment setting processing, and transmits a result of the segment setting processing, and when the control system determines that the subject vehicle is at a stop, the control system is switched to be operated in a push mode, in which the control system performs the segment setting processing with respect to the subject vehicle without receiving the request information to set a new travel-permitted segment and travel permission information indicating the new travel-permitted segment is produced and transmitted. |
