Abstract

<P>PROBLEM TO BE SOLVED: To present an inexpensive radio vehicle delivery system for allowing a vehicle delivery center to know a location position of a radio mobile station responding to a question about vehicle delivery from a radio base station. <P>SOLUTION: A GPS receiver is arranged in a taxi being the radio mobile station. The radio mobile station side desiring to receive the vehicle delivery pushes down a response switch, and transmits position information from the GPS receiver to the vehicle delivery center being the radio base station together with a vehicle number. The vehicle delivery center combines the conventional responding vehicle number display function with a means for determining a radio mobile station locating area by checking up position data from the radio mobile station with position coordinates of a preset area by a terminal unit, and displays the vehicle number and a location area name of a vehicle responding to the question about the vehicle delivery on the terminal unit. A location area range is predetermined in a vehicle delivery center side terminal unit by latitude-longitude information, and the correspondence of the location area and range information is registered. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless dispatch system such as a taxi wireless dispatch system.

[0002]

2. Description of the Related Art Conventionally, taxi companies have had a low-priced and simple response vehicle number display system for dispatching vehicles.
In this system, in response to a voice inquiry from a dispatch center which is a wireless base station, response information is transmitted when a taxi side, which is one or more wireless mobile stations that want to receive dispatch, presses a response switch. The vehicle number of the wireless mobile station that transmitted the response information to the installed terminal device is displayed on the side, the operator of the wireless base station selects the most suitable vehicle from among them, and voice dispatch instructions are given to that vehicle. It was that. In this system, the vehicle number of the responding vehicle, that is, the vehicle number of the wireless mobile station is known, but the current vehicle position is unknown, so it was not possible to determine whether the vehicle was a wireless mobile station in the vicinity of the destination vehicle. For this reason, there is a problem that when the radio mobile station selected and dispatched by the radio base station, that is, the taxi is located in a remote place instead of in the vicinity of the intended dispatch destination, the arrival at the dispatch destination is delayed. As a solution to this problem, the wireless system is a global aviation positioning system (Glob).
There is a taxi radio dispatch system that combines an electronic map with an al Positioning System (hereinafter abbreviated as GPS).
In this case, there is a problem that it takes a lot of money to develop the electronic map application program according to the needs of the customer.

SUMMARY OF THE INVENTION An object of the present invention is to provide a low-priced wireless dispatch system in which the location of a wireless mobile station that responds to a vehicle dispatch inquiry from a wireless base station can be known at a dispatch center. And

[0004]

A taxi, which is a wireless mobile station, is provided with a GPS receiver, and by pressing a response switch on the side of the wireless mobile station that wants to receive dispatch, the vehicle number and position information from the GPS receiver can be displayed. It transmits to the dispatch center which is a wireless base station. At the vehicle dispatch center, the terminal device has a function to display the conventional response vehicle number, and to determine the area where the wireless mobile station is located by comparing the position data from the wireless mobile station with the position coordinates of the preset area. combination,
The vehicle number and the location name of the vehicle that responded to the vehicle allocation inquiry are displayed on the terminal device. The range of the location area is previously determined by the latitude and longitude information in the terminal device on the vehicle dispatch center side, and the correspondence between the location area and the location position range information is registered.

1 is a block diagram showing an embodiment of the present invention. 1 is a mobile station radio, 2 is a response switch, 3 is a GPS receiver, 4 is a base station radio, and 5 is a terminal device. 2 is registered and stored in the terminal device 5 in advance,
An example of a district / latitude / longitude range correspondence table is shown. 10 is an area column of the table, and 11 is a corresponding latitude / longitude range column of the table. FIG. 3 shows an example of a display screen of the terminal device.
12 is a vehicle number column of the responding vehicle, 13 is a location area column of the vehicle, 14 is a state column of the vehicle, 15 is a display showing a state of an empty vehicle, and 16 is a display showing a state of an actual vehicle. The display is displayed, for example, in different display colors so that the display can be easily identified in consideration of visibility. The operation will be described below. The base station radio 4 of the vehicle dispatch center, which is a radio base station, simultaneously makes a voice request for a vehicle dispatchable vehicle response to vehicles in the radio base station service area. A taxi, which is a wireless mobile station desiring to dispatch in response to the inquiry, depresses the response switch 2. At this time, the response switch information and the vehicle position data of latitude and longitude detected by the GPS receiver 3 are transmitted to the base station radio 4 via the mobile station radio 1 together with the vehicle number data. On the radio base station side, the vehicle position data and vehicle number data of the radio mobile station received by the base station radio 4 are transmitted to the terminal device 5. In the terminal device 5, the vehicle position data from the wireless mobile station, the pre-registered area 10 of FIG. 2 and the corresponding latitude / longitude range 11
The area where the wireless mobile station is located is automatically identified by comparing with the table of No. 12, and the vehicle number 12, the location name 13, and the status 14 of the vehicle are distinguished into an empty vehicle 15 and an actual vehicle 16,
For example, each color is displayed with good visibility. A dispatcher at a dispatch center, which is a wireless base station, selects a vehicle in an empty state that is closest to the customer address area for which a dispatch request has been made, and sends a dispatch instruction from the base station radio 4 to the corresponding mobile station radio 1. . In the above embodiments, the taxi wireless dispatch system has been described as an example, but the present invention is not limited to this, and may be applied to a wireless dispatch system relating to another mobile station such as a home delivery vehicle. it can.

[0006]

By adding a GPS receiver, an area, a corresponding latitude / longitude range table, and an area discrimination program to the conventional low-priced and simple answer vehicle number display system, the answer vehicle number and location area can be easily set. Therefore, it is possible to realize a low-priced and simple wireless dispatch system.
