Communication region defining method, toll collection system, and program
First Claim
1. A method of defining a predetermined defined communication region in operation of a toll collection system having an on-board unit present within the predetermined defined communication region as a communication target for toll collection, the method comprising:
- a transmitter arrangement step of arranging reference transmitters capable of transmitting radio waves at a plurality of positions on a boundary line of the defined communication region to be defined;
a position location step of locating a position of each of the plurality of reference transmitters on the basis of position location signals obtained by receiving, through predetermined position location antennas, radio waves transmitted by the plurality of reference transmitters; and
a determination condition setting step of setting conditions for determining whether to set the on-board unit as the communication target for toll collection on the basis of position location results with respect to the plurality of reference transmitters.

Abstract
A communication region defining method is a method for defining a defined communication region in operation of a toll collection system having only an on-board unit present within the defined communication region as a communication target for toll collection and includes: a transmitter arrangement step of arranging reference transmitters capable of transmitting radio waves at a plurality of positions on a boundary line of a defined communication region; a position location step of locating a position of each of the plurality of reference transmitters on the basis of a position location signal obtained by receiving, through predetermined position location antennas, radio waves transmitted by the plurality of reference transmitters; and a determination condition setting step of setting conditions for determining whether to set an on-board unit as a communication target for toll collection on the basis of position location results with respect to the plurality of reference transmitters.

8. A non-transitory computer readable medium, which records a program causing a computer of a toll collection system comprising position location antennas used to locate a position of a target transmitting radio waves and reference transmitters capable of transmitting radio waves and arranged at a plurality of positions on a boundary of a predetermined defined communication region, and having an on-board unit present within the defined communication region as a communication target for toll collection to serve as:
-
a position location unit which is configured to locate the position of each of the plurality of reference transmitters on the basis of position location signals obtained by receiving, through the position location antenna, radio waves transmitted by the plurality of reference transmitters; and a determination condition setting unit which is configured to set conditions for determining whether to set the on-board unit as the communication target for toll collection on the basis of position location results with respect to the plurality of reference transmitters.
