What does an unattended system look like?

The vehicle enters from one direction → traffic lights are green → the vehicle can proceed to the weighing scale → the reader detects information on the vehicle's tag card → simultaneously, the boom gate lifts and an audio prompt says "Please proceed to the weighing scale" → the vehicle is weighed → traffic lights turn red, and the boom gate in the entry direction drops → the infrared beam sensor checks if the vehicle is fully on the scale; if not, an audio prompt says "Infrared blocked, please park the vehicle," and the software does not weigh → wait until the vehicle is parked in the correct position and the weight is stable → save the weighing data, capture a video image of the vehicle information, and simultaneously, an audio broadcast reports the weight and prompts "Weighing complete, please proceed to the offloading area," and the large screen displays the weight → the boom gate in the exit direction lifts → the vehicle exits → the boom gate in the exit direction drops.
