With the rapid development of urban construction, the management of quarries also has higher requirements. The quarry adopts RFID technology to improve the efficiency of the quarry, the safety of vehicle transportation, and the safety of workers. RFID is a non-contact automatic identification technology that can work in the harsh environment of the quarry, and has the characteristics of high temperature resistance and long-distance identification and collection, so that the quarry can realize technological and information management. The clever application of RFID technology in the quarry!
RFID technology automatically recognizes and collects information on the collection of stone materials in the quarry, the weight information of vehicles entering and exiting, the identification information of the stone materials leaving the factory, and the management of terminal computers.
Stone information collection: The information of the finished stone, such as the length, width, height and weight of the stone, is written into the electronic tag through the RFID electronic tag reader, and the user information of the stone is stored in the tag. And fix the electronic label on the stone. It is connected to the terminal computer via a wireless network to store all the stone information in the computer.
Weight information of vehicles entering and exiting: Assemble electronic tags on the vehicles that transport stones, so that we can write the weight information and vehicle information when the vehicles enter and exit into the electronic tags. The daily output of stone materials and the working conditions of the vehicle can be automatically calculated through the difference in the weight of the vehicle in and out.
Ex-factory stone identification information: Since the stones are equipped with electronic tags, we can know whether the stones on the vehicle meet the requirements of the factory by inquiring the electronic tag readers through the ex-factory goods when the stones leave the factory. When all the conditions meet the factory requirements, the access control system opens the door and sends the factory stone information back to the terminal computer. These tasks can be completed in an instant, reducing a lot of labor costs.
The terminal management computer is the focal point of the application, which comprehensively processes all data and issues corresponding operating instructions. Including all stone information, stone user information, stone factory information, etc. Users can know the current status of each stone at any time. Through the application of the electronic label system, the management of stone materials can be greatly improved and management costs can be saved. When the item with the electronic tag is within the readable range of the reader, the reader emits a magnetic field, the query signal will activate the tag, the tag requires a reflection signal according to the received query signal, and the reader receives the tag reflection back After the signal, the electronic data stored in the electronic tag is read and identified contactlessly through the decoding process of the internal circuit, so as to achieve the purpose of automatically identifying the object. Then further realize the object recognition through computer and computer network.
After the stone production is completed, the RFID electronic tag is installed on the stone and read out in a non-contact manner within a certain distance through the RFID reader. The dynamic monitoring system based on radio frequency identification technology can simultaneously non-contact, high-speed and accurate parallel tracking and identification of multiple target objects with electronic tags within a certain range, so as long as the stone passes through the place where the reader is installed, it will Automatically read the ID numbers of the electronic tags of all stones, and then the system will transmit the ID numbers of the tags and related information of the stones to the back-end system for processing.
Install RFID readers at the entrance and exit of the stone material warehouse, and install RFID readers at the gate of the factory. When the stone enters the warehouse, the information of the stone is automatically transmitted to the management computer through the RFID reader, and the computer will automatically register the stone in the warehouse. When the stone is out of the warehouse, the shipping information and the delivery location of the outbound stone can be written into the electronic label through the RFID reader, and the management computer is used for outbound registration. When the stone is loaded into the factory door, the RFID reader installed on the factory door will read the information of the electronic tag on the stone and judge whether it meets the requirements of the warehouse and the factory. If it meets the requirements of the factory, the factory door will automatically open , At the same time, it can export the transportation of the stone to the destination.
Realize the digital and scientific management of the stone materials in the quarry. Effectively manage related transportation vehicles, build an efficient and reliable management platform, grasp the transportation status of the quarry in real time, improve the management level of transportation in the quarry, and prevent various management loopholes and property losses.
