Description

  The present invention relates to a vehicle operation management system, and more particularly to a vehicle operation management system that monitors the speed and travel route of a vehicle and performs appropriate operation management.

  Construction vehicles, route buses that perform regular operations, etc. must travel on a travel route permitted in advance. In addition, a legal speed is set for the travel route, and construction vehicles, route buses, etc. must travel in compliance with the legal speed.

Therefore, various techniques for monitoring the operation of the vehicle and improving the safety have been developed. For example, a vehicle driving support system for monitoring the speed of a vehicle to prevent excessive speed is disclosed (see Patent Document 1).
The vehicle driving support system described in Patent Document 1 acquires position information of a vehicle using GPS, calculates an operation speed, compares a preset set speed with the operation speed, and determines the operation speed. A warning is generated when the set speed is exceeded.

  Also, when operating construction vehicles, monitoring personnel such as guards are placed at important monitoring points where safety is particularly important, and visual monitoring is performed.

JP 2004-287856 A

  As described above, construction vehicles and route buses must travel on a travel route permitted in advance at a speed equal to or lower than the legal speed. In particular, when a construction vehicle is operated, there is a risk of traveling off a route permitted in advance or exceeding a legal speed in an attempt to prevent a delay in the construction period. For this reason, the construction supervisor pays sufficient attention to the operation status of the construction vehicle and performs management so that safe operation is performed.

However, it is practically impossible to constantly monitor all routes along which the construction vehicle travels. In addition, even when strict operation management is performed, it may be assumed that the vehicle travels off the route due to carelessness of the driver or exceeds the legal speed. Therefore, it has been desired to develop a technology capable of performing safer vehicle operation management.
In this regard, in the vehicle driving support system described in Patent Document 1 described above, it is possible to give a warning regarding overspeed, but it has not been possible to give a warning to a vehicle that is running off the travel route.

  The present invention has been proposed in view of the above-described circumstances, and an object of the present invention is to provide a vehicle operation management system capable of monitoring the speed and travel route of a vehicle and performing appropriate safe operation management.

The vehicle operation management system of the present invention has the following features in order to achieve the above-described object.
That is, the vehicle operation management system of the present invention corresponds to position information acquisition means mounted on a vehicle, travel route storage means for storing predetermined vehicle travel route information, and a predetermined vehicle travel route. Set speed storage means for storing the set speed information, speed calculation means for calculating the traveling speed of the vehicle based on the position information acquired by the position information acquisition means, calculation results in the speed calculation means and the set speed Speed comparison means for comparing the set speed information stored in the storage means; travel route comparison means for comparing the position information acquired by the position information acquisition means and the travel route information stored in the travel route storage means; The position information acquired by the position information acquisition means, the comparison result by the speed comparison means, and the comparison result by the travel route comparison means It is characterized in that and a display control means for displaying on the device.

  In the vehicle operation management system having such a configuration, information on the current position of the vehicle is acquired by position information acquisition means such as GPS, and the travel route of the vehicle is determined based on the position information that moves with the passage of time. While grasping, the traveling speed is calculated. Then, the preset travel route and travel speed are compared with the actual travel route and travel speed, and the comparison result is displayed. Note that the position information acquisition means can be mounted on a plurality of vehicles, and the operation status of the plurality of vehicles can be monitored in real time.

In addition to the above-described configuration, the vehicle operating system of the present invention includes a speed warning unit that gives a warning to the effect that the speed comparison unit determines that the speed exceeds a set speed, and the travel route. And a travel route warning means for giving a warning to that effect when it is determined by the comparison means that the vehicle is out of the travel route.
In the vehicle operation management system having such a configuration, a warning is issued when the vehicle travels outside a preset travel route or travels beyond a set speed.

In addition to the above-described configuration, the vehicle operation system of the present invention is characterized in that the display control means performs control to display vehicle position information superimposed on map information.
In the vehicle operation management system having such a configuration, the current position of the vehicle is displayed as map information.

In addition to the above-described configuration, the vehicle operating system of the present invention is characterized in that the display control means performs control to display detailed information for each vehicle based on an instruction from the operator. .
In the vehicle operation management system having such a configuration, when a plurality of vehicles are operating, when the operator indicates a vehicle for which detailed information is desired, the detailed information of the vehicle is displayed.

In addition to the above-described configuration, the vehicle operation system according to the present invention includes, as history information, the position information acquired by the position information acquisition unit, the comparison result by the speed comparison unit, and the comparison result by the travel route comparison unit. As a history storage means.
In the vehicle operation management system having such a configuration, a history relating to the vehicle operation status is constructed as a database.

  According to the vehicle operation management system of the present invention, the operation status of the vehicle is monitored in real time by comparing and displaying the preset travel route and travel speed and the actual travel route and travel speed, Appropriate safe operation management can be performed.

  In particular, in the case where the warning regarding the travel route and the travel speed is configured, it is possible to perform a more appropriate safe operation management without overlooking the travel route violation and the speed violation.

  In addition, when the position information of the vehicle is configured to be displayed superimposed on the map information, the current position of the vehicle can be easily grasped, and more appropriate safe operation management can be performed.

  Moreover, when it is set as the structure which displays the detailed information for every vehicle, specification of the vehicle which performed the driving | running route violation and speed violation becomes easy, and it becomes possible to perform much more appropriate safe operation management.

  Moreover, when it is set as the structure which accumulate | stores the log | history regarding the operation condition of a vehicle, since the log | history of an operation condition can be reconfirmed, it becomes possible to perform much more appropriate safe operation management.
