Rear-end collision prevention device of the maintenance vehicle

摘要

[PROBLEMS] By combining the laser measurement and the GPS measurement, it provides a collision prevention device for accurate maintenance vehicles. The apparatus includes a radio 13 for receiving the location information transmitted from the wireless device 23 of the transmission or the maintenance vehicle 2 position information received generated maintenance vehicle 2 facing the at GPS receiver 12, the laser beam maintenance comprises emitting a maintenance vehicle 1 and a laser head 14 for receiving the reflected laser beam, and a radio 23 transmits the position information received generated by the GPS receiver 22 to the maintenance vehicle 1 facing and a use vehicle 2, a maintenance vehicle 1, vehicle-to-vehicle between the calculated maintenance vehicle 1 and 2 from the position information of the maintenance vehicle 2 receiving position information of maintenance for the vehicle 1 and from the maintenance vehicle 2 distance and, based on the inter-vehicle distance between the maintenance vehicle 1 measured by the laser head 14, maintenance vehicle, characterized in that it comprises a microcomputer 18 for rear-end collision prevention process between maintenance vehicle 1 is a rear-end collision prevention device. .BACKGROUND
