Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inventory management system, and more particularly, to inventory management of articles in a plurality of unmanned article storage areas from a remote office by using a portable telephone device and a radio calling device. Inventory management system.

[0002]

2. Description of the Related Art Conventionally, transmission of this kind of inventory data has generally been performed by drawing a dedicated line. However,
This construction of a dedicated line requires a lot of time and cost, and communication costs are high, which is a major disadvantage.

Therefore, there have been proposed some techniques for performing data transmission using a wireless line.

For example, there is a first method using a multi-channel radio call data communication (MCA) service and a second method using a paging receiver and a car telephone device at the same time.

As an example of this second technique, Japanese Patent Laid-Open No. 5-2
"Wireless data collection system" in 76088 publication
For example, this wireless data collection system is installed at a predetermined location, at least a paging signal receiving section, a call code detector for determining whether or not the received paging signal is a predetermined call code, and product sales. Data including a memory for storing data such as status or failure, a spread spectrum transmission unit, a transmission control unit for outputting the contents of the memory to the spread spectrum transmission unit based on the discrimination result of the calling code detector, and a transmission antenna It comprises a transmitting device and a data collecting device which is provided in a mobile unit and which has a spread spectrum receiving section for receiving the above spread spectrum transmission signal and demodulating the data, and a display section for displaying the demodulated data. The purpose of the present invention is to provide a data collection system capable of easily transmitting data from a short distance.

[0006]

According to the first conventional method, the service area for wireless transmission is small, and the terminal device side (that is, the warehouse or the vending machine side) receives another transmission-dedicated device. Since it is necessary to install each of the dedicated devices, there is a problem that the equipment cost increases.

Further, when the cellular type mobile telephone apparatus is used in the second conventional method, there is a problem that the communication cost increases.

Furthermore, the third data transmission is performed only for the collected data, and the terminal device side is controlled by wireless communication.
This method has never been proposed.

An object of the present invention is to provide an inventory management system capable of performing inventory management of articles in a plurality of unmanned article storage locations from a remote office by using a portable telephone device and a radio calling device. To provide.

[0010]

According to the present invention, there is provided an inventory management system for managing inventory of a plurality of unmanned article storage locations from a remote office, wherein each of the article storage locations is an inventory counter. An inventory management system is provided, which comprises a simplified mobile phone device for wirelessly transmitting inventory data for each article from the office to the office through a simplified mobile phone base station and a public telephone line network.

Further, each of the article storage areas is provided with a data transmission / reception control device for controlling transmission / reception of the inventory data to / from the simplified portable telephone device, and the data transmission / reception control device stores the inventory data from the inventory counter.
