MOBILE OBJECT OPERATION MANAGEMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To attain a proper and efficient operation management of mobile objects to move along a scheduled route, by making each of mobile bodies judge the positions of itself and peripheral mobile objects based on the leaving information of the mobile object sent from a base station and positional data returned from respective mobile objects while correcting its own position. SOLUTION: A DGPS(differential global positioning system) control part 12 in a control device 10 at the base station 1A finds out the correction value data of a false distance between the known position of the station 1A and a GPS satellite based on a radio wave signal supplied from a DGPS antenna 11. The correction value data are transmitted from the station 1A to each cart by using a poling message. While correcting the position of each cart itself based on the correction value data, the cart judges the position of a forward moving cart based on leaving order sent from the station 1A and a response message transmitted from the forward cart. Thereby, each cart can easily grasp the position of the forward cart and safely determine operation by the cart itself even when an instruction is not outputted from the station 1A.
