Abstract
The utility model provides an electronic device, which is used for detecting the heights of vehicles and giving audible and visual alarming prompts to drivers under the condition of vehicle height excess. The automatic vehicle height excess alarming device for the roads and the bridges consists of a control circuit, a light-emitting diode (LED) display matrix, an audible and visual alarming circuit and a photoelectric sensor circuit for detecting the heights of the vehicles, wherein the LED display matrix, the audible and visual alarming circuit and the photoelectric sensor circuit are communicated with the control circuit by circuits. The automatic vehicle height excess alarming device for the roads and the bridges has a simple structure, is stable and reliable, can reduce injury, death and economic loss due to the vehicle height excess, and is suitable for the sections of various roads and bridges with height limit requirements.
Description
Technical field
The utility model relates to a kind of road caution electronic installation.
Background technology
When entering the road that has limit for height gantry or bridge, usually can occur not being careful road caution board or the driver is not the traffic accident that knocks limit for height gantry fully aware of to own overall height owing to the driver.This has caused many casualties and economic asset loss.
Summary of the invention
For reducing unexpected generation, the utility model provides a kind of electronic installation that is used to detect height of car and can carries out the sound and light alarm prompting to the driver under the situation of vehicle superelevation.
For achieving the above object, the utility model is taked following technical scheme:
Road and bridge vehicle superelevation autoalarm, by control circuit, LED display matrix, sound light alarming circuit and the photoelectric sensor circuit that is used to detect height of car constitute; Described LED display matrix, sound light alarming circuit, photoelectric sensor circuit all with the control circuit circuit communication.
Wherein:
The LED display matrix is used for demonstration warning term and alternately flash of light, as: with the ruddiness demonstration warning clause of " vehicle surpasses No Entry ", carry out the alternately flash of light of blue light and white light simultaneously, attract driver's attention with this.
Sound light alarming circuit is used to send caution light and alarm sound, with prompting road and bridge supvr.
Photoelectric sensor circuit is used to detect vehicle and whether arrives specific limit for height height, and its testing result will influence the action of control circuit.
Control circuit is made corresponding action output according to the testing result of photoelectric sensor circuit.Testing result as photoelectric sensor circuit is the vehicle superelevation, then control circuit is with driving LED display matrix and sound light alarming circuit action, and behind the recovering state normal (vehicle of superelevation leaves photoelectric sensor) of photoelectric sensor circuit, make LED display matrix and sound light alarming circuit carry out the deferred action of specific duration.
The utility model is simple in structure, reliable and stable, can reduce because injures and deaths and the economic loss that the vehicle superelevation causes is adapted at the various road and bridge highway section configuration uses that limit for height requires that have.
Description of drawings
Fig. 1 is the circuit theory diagrams of embodiment.
Description of reference numerals: 1-control circuit; The 2-photoelectric sensor circuit; The 3-sound light alarming circuit; The 4-LED display matrix.
Embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As shown in Figure 1, road and bridge vehicle superelevation autoalarm, by control circuit 1, LED display matrix 4, sound light alarming circuit 3 and the photoelectric sensor circuit 2 that is used to detect height of car constitute.Wherein: LED display matrix 4, sound light alarming circuit 3, photoelectric sensor circuit 2 all with control circuit 1 circuit communication.
As shown in Figure 1, in the present embodiment, control circuit 1 has adopted 2 NE555 integrated packages to control, and with relay J 1, relay J 2, the relay J 3 corresponding switches of controlling red LED character reminding language, White LED light, blue led light in the LED display matrixes 4; The step switch of control circuit 1 during as the vehicle superelevation with relay J 4 is with the step switch of relay J 5 as sound light alarming circuit 3.
Under the narrow situation in road surface, the photoelectric sensor in the photoelectric sensor circuit can adopt reflective photoelectric sensor; If but the correlation photoelectric sensor is then preferably adopted when having 5 to 20 meters wide in the road surface.
What this instructions was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under principle of work of the present utility model and thinking all are considered as protection domain of the present utility model.
