<p>PURPOSE:To safely and positively perform acceptance and delivery of cargoes, and easily perform work of newly constructing and increasing stations without using an optical communication modem, etc. CONSTITUTION:After a travelling conveying device 5 is stopped at a position corresponding to a station 10, information required for performing the acceptance and delivery of cargoes on the side of the travelling conveying device 5 is sent from the travelling conveying device 5 to a main control device 15 by a first communicating means A. Then, information on the side of the station 10 is sent from the station 10 to the main control device 15 by a second communicating means B. Based on the information, a state-verification circuit 29 of the main control device 15 confirms that the acceptance and delivery of cargoes are possible, and generates a cargo acceptance and delivery starting signal. The signal is sent to the travelling conveying device 5 and the station 10 through the first and second communicating means A, B, and thus the acceptance and delivery of cargoes are safely and positively performed.</p> |
