UHF RFID solution for Automatic Weighing

T here is many in-and-out transport vehicles in the power plant, coal yard dump area and mining area. There are some procedures such as parking registration and weighing required.

If the operators input the data into the computer or register by hand writing, it will waste a lot of time and may cause many errors and human cheatings, so usually a huge economic loss may occur to the enterprise.
The intelligent weighing system has integrated the RFID technology, electronic automobile scale technology, communication technology, automatic control technology, database technology and computer network technology.
It automatically records the weight and time information of in-and-out vehicles that tagged with an electronic tag, the information store into the database of the host computer.

The system can get rid of the human errors effectively, prevents the weighing cheating and other unfavorable cases, and make sure the accuracy of the data collection and reduces economic loss.

Workflow

◇ Green signal lights on, the vehicle to be weighed enters the lane and then the red signal lamp turns on to prohibit the entrance of next vehicle into the lane.
◇ The vehicle passes the entrance-sensing coil, and then the sensing coil will generates inductive signals and the RFID Reader begin to read the card information which stick on the windshield. Compare the card information with the database of the host computer .Register the vehicle information at the same time.
◇ the vehicle drives onto the balance for weighing and the screen displays the weight information and the camera will capture the vehicle photo and store to the system at the same time.
◇ After weighing, the vehicle leave the balance and passes the ground-sensing coil and then the barrier rises up and left the vehicle go.
◇ after the vehicle pass the barrier puts down then the green signal light turn on, the next vehicle is allowed for entrance.

◇when the vehicle finish the uploading. it will pass the system again and get the vehicle weight and store the information to the system, then the software will know the goods weight.

Benefits

◇ it is suitable for the application under various extremely terrible environments such as wind, snow and rain weather
◇ the tag data is specially encoded and the electronic tags (electronic vehicle plate) cannot be faked or copied

• the vehicle tag with long life and no maintenance required;
  ◇ High-speed data collection enables the rapid weighing, improves the efficiency of the weighing and gets rid of the phenomenon of queue-up for Vehicles
  ◇Avoid human operation errors, Due to the adoption of automatic data collection, all vehicles to be weighed will be recorded by the computer automatically
  ◇ Long distance identification with 5-8m identification distance
