Camera head 23 and the signal emission module 26 of shooting transmission unit 2 all are in off position under normal circumstances, signal receiving module 21 is in holding state, in case signal receiving module 21 is received the signal that guardrail monitoring means 1 sends in this interval, then trigger camera head 23 and signal emission module 26 work of shooting transmission unit 2, with the wireless traffic administration dispatching center that is sent to of on-the-spot relevant information.
The emissive power of the signal amplification emissioning circuit 15 of guardrail monitoring means 1 adopts middle low power to transmit, transmission range is about about 1000M, such signal amplitude neither affects and disturbs the normal communication system, again can be reliable and stable communication is given shooting transmission unit 2.The above wireless launcher of power in 26 employings of signal emission module of shooting transmission unit 2 is with the wireless communication connection of assurance with the traffic control center.
To sum up, the road traffic guardrail intelligent management system of present embodiment, simple in structure, easy for installation, cost is lower; Only have when the run-off the straight of road guardrail reaches the angle that presets, just the relevant device of trigger message transmission is started working, not standby during run-off the straight, thereby but power saving and can effectively prolong the serviceable life of system; Be arranged on the middle guardrail monitoring means of road and the shooting transmission unit that is arranged on the light pole and all adopt the solar cell self-powered, both can save electric energy, save again the trouble of frequent dry cell, increased the reliability of system works; System can find in real time that road guard topples and relevant information is uploaded to the traffic administration dispatching center in real time, thereby can improve significantly instantaneity and the validity disposed when the traffic administration dispatching center accident (fault) occurs to road guard, thereby promote the integrity of road guard, reduce the generation of traffic hazard, promote city image.
Above embodiment is the explanation to the specific embodiment of the present invention; but not limitation of the present invention; person skilled in the relevant technique is in the situation that does not break away from the spirit and scope of the present invention; can also make various conversion and obtain the corresponding technical scheme that is equal to variation, so all technical schemes that are equal to all should be included into scope of patent protection of the present invention.
