積み荷管理システム、及び積み荷管理システムの送信機
Document Type and Number:
Japanese Patent JP3602221
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate cargo loading and unloading confirmation errors by providing a weak output transmitter that is attached to every cargo, an on- vehicle receiver containing a signal detection means, and a cargo management means which manages the cargo loading and unloading states. SOLUTION: A crew member inputs a delivery invoice to an input part 15a to read the cargo numbers, the delivery spots, etc., via a memory 15c. When the crew member loads the cargo (equipped with a transmitter 11) of the number shown on a display 15b into a cargo room, a carrier detection circuit 12b of a receiver 12 prepared in an operation room outputs H since the carrier signal is set at reference level or higher. When the cargo arrives at a spot B, the cargo number corresponding to the spot B is retrieved of the cargo data stored in the memory 15c and then shown on the display 15b. When the crew member unloads the cargo of the corresponding number out of the cargo room, the circuit 12b of the operation room output L since the carrier signal is reduced down to the reference level or less. Thus the unloading confirmation errors of cargoes can be prevented.
