Smart guardrail

The invention provides an intelligent guardrail. The intelligent guardrail mainly comprises bases, lamp caps, upright columns, an upper cross beam, a lower cross beam and a plurality of standpipes, wherein rope connecting mechanisms are internally arranged in the upright columns; pavement temperature sensors and pavement waterlogging alarms are internally arranged in base bodies of the bases; each lamp cap comprises a solar cell panel, a circuit board, a data storage, a signal collector, an aluminium floriation and a plurality of three color variable lamps; each rope connecting mechanism comprises a polyethylene rope, a locking fixed seat and a locking fixed cap; and the polyethylene ropes pass through the locking fixed seats and the locking fixed caps to be respectively connected with the lamp caps and the bases. The intelligent guardrail has the beneficial effects that the connection firmness between the upright column and the base and between the upright column and the lamp cap is greatly improved by arranging the rope connecting mechanisms inside the upright columns; the pavement temperature sensors and the pavement waterlogging alarms are internally arranged in the bases, and the solar cell panels, the circuit boards, the data storages and the signal collectors are arranged on the lamp caps, thus achieving multiple functions of environment monitoring and lighting warning; and the intelligent guardrail has the advantages of elegant appearance, simplicity and convenience in installation and high intelligent degree.
