PROBLEM TO BE SOLVED: To provide a vehicle intrusion warning system for allowing a site worker such as an operator to reliably recognize a danger.SOLUTION: The vehicle intrusion warning system includes a plurality of road cones 10 to be installed on the boundary of a site zone A, and a main transmitter receiver 20. Each road cone 10 includes detecting means 11 for outputting an alarm signal α when detecting the movement or inclination of the road cone 10, transmitting means 12 for transmitting the alarm signal α, receiving means 13 for receiving a control signal &bgr;, a light emitting part 14, and control means 15 for controlling the light emission pattern of the light emitting part 14 corresponding to the control signal &bgr;. When the transmitting means 12 of any road cone 10 transmits the alarm signal α, the receiving means 13 of the remaining plurality of road cones 10 receives the control signals &bgr; and the control means 15 of the road cones 10 controls the light emission patterns of the light emitting parts 14 of the road cones 10 to be changed into alarming light emission patterns, respectively.SELECTED DRAWING: Figure 2 |
