Application of UHF RFID Coal Mine Vehicle Intelligent Weighing Management

For a long time, there have been a large number of material transport vehicles coming in and out of the mining area every day, and procedures such as parking, registration, and weighing have to be carried out. The operator manually enters the data into the computer, which is not only time-consuming, but also has a high error rate. In addition, it is easy to breed human fraud , causing large economic losses to the enterprise. Therefore, how to quickly and effectively collect data, remote inspection and judgment system in the mining area vehicle import and export, weighing area, and unloading area has become the primary issue.

Combined with the current situation of manual management of mine vehicles, UHF RFID intelligent weighing management of coal mine vehicles can automatically record the license plate number, weight information, time information, etc. of vehicles equipped with electronic tags, and write them into the host database, which can effectively eliminate artificial errors, prevent overbalance blockage, cheating and other situations, and ensure the accuracy of original data collection.

The workflow of RFID technology coal yard vehicle management:

1. Registration

The mine registration office first registers the vehicles entering the mine, and distributes a special label for ore transportation, and then saves the card number, vehicle plate number, owner's name, entry time and entry location related information of the label in the in the host database.

2. Billing

Only customers who have been issued a special label for transporting ore can go to the billing office of the mine to invoice and purchase ore.

3. Empty car weighing

After the customer invoices, the ore truck can be driven into the truck scale channel for weighing. The vehicle detector installed at the crossing senses that there is a car coming in, and sends the signal to the front gate and signal light. The barrier gate is closed immediately, and the signal light turns red. Prompt the driver to drive slowly, and at the same time require the weighing instrument and the reader to start working. After the tag on the ore truck is read by the reader, the reader sends the car’s information to the host, instructs the electronic scale to start sending the car’s weight information, and the camera monitors whether the car is parked at the designated location and captures images. When the host receives the card number and weight information, it will accurately record and back up the information, and then issue an instruction to open the gate, and the ore transport vehicle will drive into the mine for loading.

4. Loading

After the empty ore truck is weighed, it can be driven into the mine for loading.

5. Ore loading and weighing

After loading ore, the ore truck needs to drive into the truck scale road again for weighing. The vehicle detector installed at the crossing senses that there is a car coming in, and sends the signal to the front gate and signal light. The barrier gate is closed immediately, and the signal light turns red, prompting The driver drives slowly, and at the same time requires the weighing instrument and the reader to start working. After the tag on the mining vehicle is read by the reader, the reader antenna transmits the information of the vehicle to the host, instructs the electronic scale to start transmitting the weight information of the vehicle, and at the same time, the camera monitors whether the vehicle is parked at the designated location and captures images. When the host receives the card number and weight information, it will accurately record and back up the information, and then issue an instruction to open the gate, and the ore transport vehicle will drive into the mine ticketing office to issue tickets.

6. Billing

After the ore truck is loaded, it needs to go to the billing office again for billing. The billing office checks whether the information on the two weighings of the ore truck is consistent. When all the information is consistent, the billing office will automatically calculate the net weight of the transported ore according to the management system and issue the bill.

7. Appearance

Finally, the coal truck can hold the ticket and leave the coal yard after being inspected by the guard. Automatically record various required information such as vehicle entry time, entry location, vehicle weight, and vehicle owner unit. RFID technology automatically collects fast, which can realize rapid vehicle weighing, improve weighing efficiency, and reduce excessive vehicles. And cause the phenomenon of queuing overbalance. All overweight vehicles are automatically recorded by the computer, eliminating the need for manual intervention, automatic recording of data, and automatic release. By realizing automatic measurement, the time required for each operation link is shortened, the loading and unloading capacity of the measurement system is improved, labor intensity is reduced, and labor costs are saved. Through the automatic collection of RFID electronic tags installed on coal transport vehicles, real-time monitoring of the measurement site can be quickly realized, so that the data information collection in the measurement process is fully automated and the data is accurate and fast, ensuring the accuracy and fairness of information collection, and improving work efficiency. Reduce economic loss.

8. Destination unloading ore weighing

The ore truck reaches its destination. Before unloading, drive into the truck scale road at the destination for weighing. The vehicle detector installed at the crossing senses that there is a car coming in, and sends the signal to the front gate and signal light. The barrier gate is closed immediately, and the signal light turns red to remind the driver The operator drives slowly, and at the same time requires the weighing instrument and the reader to start working. After the tag on the ore truck is read by the reader, the reader sends the car’s information to the host, instructs the electronic scale to start sending the car’s weight information, and the camera monitors whether the car is parked at the designated location and captures images. When the host receives the card number and weight information, it will accurately record and back up the information, and then issue an instruction to open the gate.

9. Unloading

After the ore truck is weighed, it can be driven into the mine for unloading.

10. Empty car weighing

After the ore truck is unloaded, the empty car is weighed. At the same time, the invoice is issued at the billing office. The billing office checks whether the information on the two weighings of the mine car is consistent. Wait, if all the information is consistent, the invoicing office will automatically calculate the net weight of the ore transported according to the management system to issue an invoice, and return the special label for ore transport.

11. Calculation and weighing

The calculation of the whole ore loading process is divided into three calculations. The weighing of the loading ore is compared with the weighing of the empty truck to calculate the weight of the loading; Comparing with the weighing at the unloading yard, calculate the transported ore weight, and compare with the ore weight calculated for the first time to calculate whether there is any loss or residual ore.

What are the advantages of UHF RFID coal mine vehicle intelligent weighing management?

safety

RFID electronic tags cannot be forged or copied, which fundamentally eliminates the phenomenon of copying, forgery, and cheating...

Strengthen management to prevent favoritism and fraud

The UHF RFID electronic tag is pasted on the windshield of the car, and the weight weighed by the weighbridge each time strictly corresponds to a card and a car.

Protect the safety of this area and prevent illegal vehicles from entering

This system can be integrated with the parking lot management system. Only vehicles carrying legally authorized electronic tags can enter the mine loading and weighing area, thereby improving the security of the area.

Can transmit information over long distances

It can carry out remote control and group control to make the system truly automatic and intelligent, and can be connected to the computer network to automatically analyze, calculate and print data records and reports.

Information collection automation

The weighing data output by the truck scale and the electronic tag card number installed on the mine truck are processed by related equipment and then transmitted to the computer. The computer displays the weight of the cargo being pulled by the vehicle and Stores it in the computer's database. Users can query, summarize, print and other operations as needed, thus realizing the automation of information collection.
