1. the system is powered by a battery, and a communication network is established among the devices in a zigbee ad hoc network mode, so that the system is convenient to expand, field wiring is not needed, and a warning area can be flexibly arranged.
2. The effective detection distance of the portable laser detection alarm can be expected to reach 500 meters, and the portable laser detection alarm can be bridged and expanded, so that the requirement of the warning range of a construction area can be effectively met.
3. Compare traditional road signboard of being under construction night, this system has increased audible-visual alarm, and when the vehicle was run into, portable laser detection alarm sound was the highest 120 decibels among the wireless sensor early warning network, can effectively remind driver and constructor tired driving.
4. Constructors can timely acquire vehicle intrusion information in a warning area and position the vehicle intrusion direction through the portable alarm receiver in the wireless sensor early warning network of the system, so that the constructors can more effectively handle the accident situation.
