Earth and sand management system of a construction site using RFID}

The present invention relates to a soil management system at a construction site using RFID, and more specifically, to transport soil based on the tag information of the RFID tag provided in the soil transport vehicle entering and leaving the construction site and vehicle weight sensing information at the time of entering and leaving. The present invention relates to a soil management system of a construction site using RFID that enables to determine the validity of a load on a vehicle and to use the soil management information generated as a result of the determination as a data for calculating a freight cost of the vehicle.

In general, after the foundation work at a construction site or a large-scale civil engineering site, a large amount of soil is generated, and such soil is carried on earth transport vehicles such as dump trucks to be taken out to the outside. At this time, the construction site pays a fare determined according to the number of times of operation of the earth and sand transporting vehicles to take out the earth and sand.

Currently, in most construction sites, the managers who stay in and out of the earth and sand transport vehicles directly check the vehicles and write the contents by hand.

This method requires a lot of time and manpower by the manager to directly check the load of the earth and sand for the earth and sand carrying vehicles entering and leaving the construction site, as well as delays due to the delayed construction of many vehicles. There was a problem that occurred.

In addition, there is a problem of paying more than the expected cost if the load of the soil transport vehicle is not appropriate, and it is inefficient in management and duplication of work such as the rewriting of handwritten documents is required. There was this.

In other words, when relying on document records using manual labor as a means for controlling and managing the access of vehicles carrying soil and soil at the construction site, it takes a lot of time and management personnel to enter and manage the vehicle, as well as the loss of document records. It can also be used incorrectly to calculate fares for soil-carrying vehicles due to misunderstandings, which can be a source of disputes about fares.

On the other hand, the RFID (Radio Frequency Identification) system is a radio recognition technology that automatically recognizes data stored in an RFID tag with a microchip using a radio frequency using an RFID reader. An RFID tag stores tag information and exchanges data with a protocol.
