Abstract

PURPOSE:To display the moving distance of a vehicle within a service area by calculating the moving distance of a vehicle basing on the increase amount of a count value of a wheel revolution counting means and the travelling distance per revolution. CONSTITUTION:A wheel revolution counting means counting the number of revolutions of the vehicle wheels and a count value transmission means transmitting the count value of the wheel revolution counting means after the vehicle is in the service area of the MCA control station via an MCA moving station are mounted. The MCA moving station 11 incorporated on a vehicle 10 and an MCA command station 12 installed at an objective point Pa are connected by radio through the MCA control station 13. The vehicle 10 travelling an expressway L2 enters the service area of the MCA control station 13 at the point P5. For example, when a communication request is sent from the MCA command station 12 to the MCA mobile station 11, the identification code of the MCA mobile station 11 is sent through the MCA control station 13 to the MCA mobile station 11. The vehicle 10 accepts the control code of the MCA control station.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position information collecting device using an MCA, and more particularly to a position information collecting device for collecting position information of a long distance transportation truck using the MCA.

[0002]

2. Description of the Related Art Long-distance transportation trucks regularly transport between distribution centers that are separated by a considerable distance, but it is important to accurately know the arrival time at a target distribution center for subsequent vehicle allocation planning. As a method for grasping the position of a moving body such as a long-distance transportation truck, a method using bidirectional communication using artificial satellites is known.

This is a system for measuring the position by using an artificial satellite, and it is possible to obtain highly accurate position information, but the device mounted on the moving body is expensive and all long-distance transportation trucks can be used. Not a thing. In order to solve this problem, a position information collecting device using wide area MCA (Multi Channel Access) is also proposed.

The MCA is a commercial radio system, which is composed of a control station, a command station, and a mobile station, and the control station searches for an empty channel in response to a communication request from the command station or the mobile station and searches the command station and the mobile station. The communication connection between the command station and the mobile station is made by giving an instruction to. 1
The service range of one control station is 20-30km,
By registering one mobile station in a plurality of control stations along the route along which the mobile station moves, it is possible to communicate over a wide range.

Therefore, it is possible to specify the position of the mobile station by recognizing that the command station has moved from the service range of one control station to the service range of another control station.

[0006]

However, it is necessary to register in a plurality of control stations, and the resolution is 20 to 30.
Since it is km, the accuracy is not sufficient. Furthermore, location information is not required at all points from the origin to the destination,
Accurate location information is needed as you get closer to your destination.

The present invention has been made in view of the above problems, and uses an MCA registered only in an MCA control station that includes a destination in the service range of position information from the time of passing a predetermined point. An object of the present invention is to provide a position information collecting device that collects positions.

The distance traveled by the vehicle from the beginning is displayed on the MCA command station. In the position information collecting device using the MCA according to the second aspect of the invention, the count value of the wheel rotation speed counting means is reset when the vehicle passes through a specific point along the travel route of the vehicle, so that the vehicle from the specific point is reset. The moving distance of is displayed on the MCA command station.

In the position information collecting apparatus using the MCA according to the third invention, the count value of the wheel rotation number counting means is reset when the service range of the MCA control station is entered. The moving distance of the vehicle after entering the service range is displayed on the MCA command station. In the position information collecting apparatus using the MCA according to the fourth aspect of the present invention, the MCA command station determines that the vehicle has reached the destination when the MCA command station determines that the vehicle has stopped after moving for a predetermined distance. Display on the station.
