Material management system

Abstract

We provide a materials management system that can manage multiple types of materials, including large and heavy materials used at civil engineering and construction sites, as well as small and lightweight materials. [Solution] The material management system 1 at a civil engineering or construction site comprises a material weighing unit including a plurality of weighing devices 500, a basket 20 that can be placed on the plurality of weighing devices 50 constituting the material weighing unit and is removable from the weighing devices, and a data processing unit that can communicate with the weighing devices of the material weighing unit. The data processing unit stores an inventory management unit master in which a material identifier that identifies the type of material and weight information relating to the weight per unit quantity of the material corresponding to the material identifier are associated. The data processing unit refers to the inventory management unit to obtain weight information corresponding to the type of material placed in the basket 20, and manages the quantity of material based on load data received from the plurality of weighing devices 500 received from the material weighing unit and the acquired weight information.

Claims

1. A materials management system at civil engineering or construction sites, A material weighing unit including multiple weighing devices capable of transmitting load data indicating the applied load, A storage unit that can be placed across multiple weighing devices constituting the material weighing unit and is removable from the weighing devices, The material weighing unit comprises a data processing unit capable of communicating with the weighing device of the material weighing unit, The aforementioned data processing unit is The system stores an inventory management unit master in which a material identifier that identifies the type of material is associated with weight information relating to the weight per unit quantity of the material corresponding to that material identifier. The aforementioned data processing unit is By referring to the aforementioned inventory management unit master, weight information corresponding to the type of material placed in the storage unit is obtained. Based on the load data received from the plurality of weighing devices constituting the material weighing unit and the acquired weight information, the quantity of the material is managed.
