This anti-collision system is a safety distance measurement system. It is developed based on UWB technology, the accuracy can reach the centimetre level, and the vehicle accident can be effectively prevented through accurate distance measurement and pre-alert. In specific applications i.e. forklift, when the distance between vehicles and pedestrians is less than the set minimum value, the RFID tags connected to the base station will send out alarms in real time to prevent collisions and accidents.
