fig1 shows a section of a road 10 that is being monitored with the wildlife warning system according to the invention . mounted at the edges 11 , 12 of the road 10 are traffic posts 13 , usually at intervals of 25 meters . every 25 meters , the traffic posts are equipped with warning devices of the wildlife warning system according to the invention alternately on the left - hand and right - hand sides of the road . in the case of road sections with a lower level of risk , the devices can also be fitted every 50 meters , for example . the warning devices 14 can communicate with one another and / or with a base station 15 situated nearby wirelessly . by way of example , the base station 15 is equipped with a gsm or umts module 16 that it can use to communicate with a remote service control center 17 . for wireless communication with the warning devices 14 in the network , the base station 15 has a radio module 18 that can be used to communicate over relatively short distances of between a few hundred meters and a few kilometers . the network may also be configured such that a short range for the communication module 18 prompts communication only with a warning device 14 that is situated in direct proximity to the base station 15 , and the warning devices 14 that likewise have communication means for wireless communication with other warning devices forward appropriate data to the destination warning device , which means that it is also possible for relatively long road sections having relatively low - power and therefore energy - saving radio communication means to be monitored . the radio communication between base station 15 and warning devices 14 is symbolized by the arrows 19 in fig1 . the radio communication of the warning devices 14 among one another is symbolized by arrows 20 . fig2 shows a warning device 14 of the wildlife warning system according to the invention that can be mounted on a road traffic post 13 , for example . the warning device 14 has a weatherproof housing 21 that contains the power supply 22 , for example a lithium polymer storage battery , which is indicated only symbolically and is powered by a solar module 23 , a light - emitting diode 24 that serves as a visual signal generator , a loudspeaker 25 that serves as a visual signal generator and a microcontroller 26 for controlling the two signal generators . furthermore , the microcontroller 26 can ensure charge protection for the power supply 22 . furthermore , the housing 21 contains communication means 27 that comprise an antenna 28 for communicating with other warning devices or with the base station 15 . furthermore , the warning device 14 has a headlamp sensor 29 for detecting approaching vehicles , the communication means 27 are likewise controlled by the microcontroller 26 . finally , the housing 21 contains a position sensor 30 , the signals from which are likewise evaluated by the microcontroller 26 , so that in the event of an accident , for example , when the warning device 14 is no longer in its proper position or in the event of theft of the warning installation , an appropriate alarm can be triggered and transmitted to the service control center 17 via the communication means 27 and the base station 15 . conventional traffic posts can easily be ripped out of the ground , which means that a traffic post with a warning device can also easily be stolen . to improve theft prevention , the traffic post 13 or else a separate mounting rod on which the warning device 14 may be mounted can therefore be provided with a mechanical theft prevention system . a preferred embodiment of such a theft prevention system is shown in fig3 , wherein the traffic post 13 is provided with a ground anchor 30 that is connected to the warning device 14 by means of a wire cable 31 . the ground anchor 30 has two or more foldout arms 32 that , after the post 13 has been inserted into the ground 33 , can be folded out through openings 34 provided in the outer wall of the post 13 by means of the securing wire 30 or a separate pull cable 34 , so that the post with the warning device can be securely anchored in the ground . fig4 shows a variant of the warning device in fig3 . in this case , the traffic post 113 again has a ground anchor 130 , which in the example shown can be operated by means of a rod 131 . by rotating the rod 131 , one or more ( two in the example shown ) arms 132 are folded out . after the post 113 has been inserted into the ground , the rod 131 is rotated by means of a twist grip that can be inserted into the post 113 , so that the arms can be folded out through openings 134 provided in the outer wall of the post 113 ( cf . fig5 , which shows a schematic cross section through the wildlife warning device along the line v - v in fig4 ).
a wildlife warning system that comprises at least two independent warning devices , wherein each warning device has an electric power supply , at least one signal generator , a microcontroller for controlling the signal generator , and a communication means for wireless communication with other warning devices and / or with a base station for the purpose of forming a wireless network of wildlife warning devices .
