When green signal lights, 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 1 that generates inductive signals, and the reading and writing device uploads the card information to the database of the host computer after reading the card and calls out the vehicle information at the same time.
The vehicle drives onto the balance for weighing, and the screen displays the weight information and snaps the image information at the same time.
After the weighing, the vehicle goes off the balance and passes the ground-sensing coil 2, and then the lever rises up.
After the vehicle pass the lever puts down, then the green signal lamp turns on, the next vehicle is allowed for entrance. (According to the actual situation, another flow is also available: the lever rises up after vehicle number information identified then the vehicle drives onto the balance for weighing and the lever prevents the next vehicle from driving onto the balance) (See the chart in above)
