PARKING METER PARKING GUIDANCE SYSTEM AND PARKING METER MANAGEMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a parking meter parking guidance system which is easily realized at low cost. ;SOLUTION: A display machine 1 with a radio set displays the vacant states of respective parking meters 3a to 3d. Radio sets 2a to 2d are connected to the parking meters 3a to 3d. For the radio sets 2, specific small-power radio sets which are usable without any license, economical, and easy to handle are used, and data can not be sent directly to the display machine 1 from the radio sets 2c and 2d of the distant parking meters from the display machine 1 such as the parking meters 3c and 3d. To cope with this, each radio set 2 is provided with a repeating function to transmit the data on the way of relay by bucket from the parking meter 3d which is the farthest from the display machine 1 to the display machine 1. In this system, the repeating radio sets send the received data together with their own data in addition. Repeating destinations make discrimination by using IDs assigned individually to the radio sets 2.;COPYRIGHT: (C)1999,JPO
