Position recognition apparatus for a personal rapid transit control system
First Claim
1. A position recognition apparatus for a personal rapid transit, system including a vehicle guideway (10), for aerial-installation at railways in urban areas, and small vehicles (80) for traveling along the vehicle guideway (10) at a time interval of as short as 0.5 seconds between vehicles to provide respective small units of passengers with rapid transit, the guideway comprising two sides and further comprising control ducts attached to both said sides of the guideway, comprising:
- position designation means, comprising bar code members (50a &
50b) comprising strips arranged in a continuous band configuration on which bar-codes (50) are printed by engravement, wherein said bar-code members (50a &
50b) are attached to the control ducts (21a &
21b) attached to both said sides of said guideway (10) to be displayed towards said vehicles (80), for designating sections and respective corresponding positions of said guideway (10) as at least one member of the group consisting of figures and letters, to designate passage positions where said vehicles (80) travel along said guideway (10);
control means (70);
position recognition means, comprising bar code scanners (60a and 60b) installed on said vehicles (80) to be opposite to said position designation means, for reading out and recognizing a current position of said vehicles (80) from bar codes of said position designation means, and transmitting recognized position signals of said vehicles (80) to said control means (70); and
said control means (70), disposed adjacent to said position recognition means, for receiving the position signal supplied from said position recognition means of said vehicles (80), and controlling travelling speed of said vehicles (80) and time intervals between vehicles on the guideway (10).

Abstract
A position recognition apparatus for personal rapid transit. The personal rapid transit system comprises a chassis (40) for moving at the inside of a guideway (10) and a chamber for passengers being mounted on the chassis (40) at the outside of the guideway (10). The chassis (40) is provided with guidance wheels (41 and 42), electric linear motors (44a and 44b), a switching device, brakes, a control apparatus (70) and electric power supply devices. Bar code scanners (60a and 60b) are installed at both sides of the chassis (40) in the inside of the guideway (10). Bar codes include figures and letters indicating sections and positions at a certain interval on the guideway (10), and are printed on bar code members (50a and 50b) having a predetermined width which is made of plastics. The plastic bar code members (50a and 50b) on which the same bar codes are printed are attached to both sides of the guideway (10). The scanners (60a and 60b) recognize positions and speed of the vehicles (80) from bar codes which are arranged opposite to the scanners (60a and 60b) fixed at the chassis (40) of the vehicles (80), and transmit the data to a computer which is installed adjacent to the scanners (60a and 60b) for controlling the vehicles (80). The computer controls the driving motors of the vehicles (80) to thereby provide effects of performing accurate interval maintenance and preventing in advance rear-end collision and collision between vehicles under the control of interval and speed.
