Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle operation management device that records the running position, speed, and time of a moving vehicle such as an automobile, a ship, or an airplane, and manages the operation of the vehicle.

Conventional vehicle operation management devices record the distance traveled, speed, and time of the vehicle, but do not record the traveling position, so it is not possible to know the route traveled by the vehicle. In addition, methods for detecting the driving position of a vehicle include a method that receives radio waves from a radio lighthouse installed at a predetermined location, and a method that stores predetermined roads, topography, etc. to the destination in a computer. However, the former method cannot be used for vehicles traveling far away from radio lighthouses and in places where radio waves cannot be received, and the method itself is expensive, making it particularly unsuitable for cars, etc., and the latter method is expensive. Not only that, but it also had the disadvantage that the route to the destination was limited. Therefore, it has been difficult to record the traveling position of a vehicle with the conventional vehicle operation control device.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such conventional drawbacks, and to provide a relatively inexpensive vehicle operation management system that can record the driving position of a vehicle regardless of the driving location or driving route.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of a vehicle operation management system according to the present invention, where 1 is a distance sensor that detects the distance traveled by the vehicle, and 2 is a sensor that senses the earth's magnetic field to detect the direction of travel of the vehicle, such as north, south, east, west, etc. Orientation sensor, 3
takes the output signals of distance sensor 1 and direction sensor 2 as input, and calculates the distance traveled by the vehicle every time it travels a certain distance into a component parallel to the longitude line (north-south direction component) and a component parallel to the latitude line (east-west direction component). 6 is a clock device that outputs a signal corresponding to the time; 7 is a speed device that outputs a signal corresponding to the traveling speed of the vehicle; 4 is a clock device that outputs a signal that corresponds to the traveling speed of the vehicle;
A storage device such as a RAM that stores the output signals from the clock device 6 and the speed device 7, and sequentially adds and stores the output signals from the first arithmetic circuit 3; 5 stores the information stored in the storage device 4; Each represents a display device for display.

To explain its operation, the stored value of the storage device 4 is reset based on the output signal from the first arithmetic circuit 3 at the starting point. When the vehicle starts running, the distance sensor 1 outputs a signal corresponding to the distance traveled, and the direction sensor 2 outputs a signal corresponding to the direction of travel of the vehicle. First arithmetic circuit 3
is from the output signals of distance sensor 1 and direction sensor 2,
Every time the vehicle travels a certain distance (for example, 10 m), an operation is performed to decompose the distance into a component parallel to the meridian (north-south component) and a component parallel to the latitude (east-west component). That is, the distance traveled is decomposed into the xy coordinate system. The storage device 4 sequentially adds and stores the x and y components at regular intervals. For example, if the driving location is 3 km east and 4 km south of the starting point, the storage device 4 stores x=3 and y=-4. That is, the storage device 4 stores the position of the driving place viewed from the starting point (x=0, y=0). On the other hand, a signal corresponding to the time is input from the clock device 6, and a signal corresponding to the traveling speed of the vehicle is input from the speed device 7, so the storage device 4 stores the current driving location ( The time and speed are stored in correspondence with the x and y values). The stored information is displayed on the display device 5 each time or all at once upon arrival at the destination. The display device can be a recording paper.

FIG. 2 shows another embodiment of the present invention, in which the calculation results of a second calculation circuit 8 which receives the output signals of the distance sensor 1 and the clock device 6 and calculates the average speed of the vehicle are stored in the storage device 4. The structure is the same as that of the embodiment shown in FIG. That is, this is an embodiment which includes a second arithmetic circuit 8 in addition to the speed device 7 as a speed detection device for detecting the speed of the vehicle, and in this case, the average speed as well as the absolute speed of the vehicle can be stored and displayed.

As described above, in the present invention, the position and speed of a vehicle can be known for each unit of time by simply installing this device in the vehicle without the need for other equipment such as a radio lighthouse. This system has the advantage of being able to easily and reliably perform operation management, including the travel location, and being simple in configuration, it can be provided at a low cost.
