Description of drawings
Fig. 1 is the structured flowchart of the icing monitoring early-warning system of bridge floor of the present utility model.
Below in conjunction with drawings and Examples the utility model is further explained.
Embodiment
As shown in Figure 1, the bridge floor of the present utility model monitoring early-warning system that freezes comprises supervisory system and early warning system; Wherein, described supervisory system comprises a plurality of freezing sensor, shift knob and signal projectors that are installed on the bridge floor, and the output terminal of freezing sensor connects signal projector, and the shift knob of supervisory system is connected with signal projector; Described early warning system comprises shift knob, signal receiver, A/D converter, single-chip microcomputer and display, wherein, signal receiver is by the input end of A/D converter connection single-chip microcomputer, and the output terminal of single-chip microcomputer connects display, and the shift knob of early warning system connects single-chip microcomputer; Described signal projector links to each other with described signal receiver by optical fiber.
Described freezing sensor is used for measuring the ice layer thickness of bridge floor.Freezing sensor adopts the flat diaphragm type freezing sensor based on piezoelectric effect in the present embodiment, and they adopt flat mounting means evenly to be arranged on the bridge floor, and namely the detection faces of each freezing sensor is concordant with bridge floor, with the icing situation of accurate perception bridge floor.At bridge transversely, with the hardened verge center line freezing sensor is installed on the center line in every track; Bridge vertically on, adorn a freezing sensor every 50 meter amperes.
Described signal projector adopts the optical fiber analog signal transmitters.
Described signal receiver adopts the optical fiber receiver of the analog signal, and its model need adapt with the signal projector model.
Described A/D converter adopts 12 A/D converters at a high speed, and the analog quantity that is used for signal receiver is received converts digital quantity to and sends to single-chip microcomputer.
Described single-chip microcomputer is used for analyzing and handling the data that receive, and sends instruction according to the result after handling to display.In the present embodiment, adopt the STC8051 single-chip microcomputer.
Described display is used for display reminding or information warning.In the present embodiment, display adopts the LED display board, and its size and word coca are determined according to design rate and the laying condition of corresponding road.Because bridge floor ice hazard grade adopts colour code, so the LED display board adopts black matrix with outstanding early warning font color;
Described supervisory system shift knob is located at end of the bridge, and described early warning system is installed in end of the bridge by erecting frame, and erecting frame adopts stainless steel to be welded, and display is mounted to the erecting frame upper end, and the early warning system shift knob is located at the erecting frame bottom to make things convenient for manually-operated.
