Abstract
The utility model discloses a LED caution signboard, which comprises a support bar and a casing provided on the support bar. A PCB plate and a control circuit connected with it are fixed in the casing. The control circuit is connected on the control panel, and the LED members are arranged on the PCB plate. The box shed is provided with a transparent cover plate used to seal the members in the box. The utility model is characterized in that the LED members are arranged and combined into various caution sign patterns, and the control circuit contains a single chip microcomputer that automatically control the LED members to display various caution sign patterns. The LED caution signboard is capable of circulating and changing into different caution sign patterns automatically and sequentially, thereby achieving the multifunctional caution signing and saving the cost input of location and facilities. Meanwhile, the dynamic process of changing different caution sign patterns further enhances the signing effect of the LED caution signboards, which is beneficial for the pedestrians to notice the indicator signals.
Description
Technical field
The utility model relates to a kind of LED caution direction board.
Background technology
Mostly the caution direction board of outdoor application now is stenciling static caution Warning Mark on the board plate.The shortcoming that this caution direction board exists is: 1, the caution Warning Mark is static, can only represent a kind of caution indicator signal pattern on the direction board all the time, and the caution direction board can not the different caution indicator signal of dynamic mapping; 2, by warning the reflective naturally caution indicator signal of transmitting of direction board, can not autoluminescence, under the situation of weather conditions difference, as overcast and rainy, greasy weather, perhaps night, this caution direction board lacks good light condition, just can not be effectively reflective, and the light of reflection does not have strong penetration power yet, thereby can not found by the people very early at a distance, can influence the caution indicating effect.
Along with the development of LED application technology, LED has begun to be applied to indicate the caution field, and existing LED caution direction board has self luminous advantage, can transmit the caution indicator signal under the situation of weather conditions difference at a distance.And present this LED caution direction board can only be represented a kind of caution indicator signal pattern, because some place need be provided with multiple caution indicator signal, that just need be provided with the LED caution direction board of the different caution of a plurality of expressions respectively indicator signal.Because present LED caution direction board, price still compares expensive, and the input cost that this will inevitably increase the place facility greatly is unfavorable for the extensive utilization of LED caution indication product.
The utility model content
Technical problem to be solved in the utility model provides a kind of LED caution direction board, this kind LED caution direction board can be by the continuous conversion caution of the program of setting indicator diagram, play the effect of multinomial caution indication, thereby saved the input cost that is used for the place facility, to overcome the deficiency that prior art exists.
In order to solve above-mentioned technical matters, the technical solution adopted in the utility model is:
A kind of LED caution direction board, comprise support bar and the casing that is located on the support bar, the control circuit that the casing internal fixation is provided with pcb board and is connected with PCB, control circuit connects control panel, arrange on the described pcb board and be fixed with the LED assembly, box mouth is provided with the transparent cover plate of above-mentioned device sealing in casing, it is characterized in that: described LED assembly permutation and combination on PCB becomes multiple caution indicator diagram, includes the single-chip microcomputer that automatic control LED assembly shows different caution indicator diagrams in the described control circuit.
Described multiple caution indicator diagram has three kinds, promptly is respectively to prohibit fiery pattern, speed limit pattern, horn-blowing control pattern.
Adopt above-mentioned technical scheme, the utility model has the advantages that, the Automatic Program that this LED caution direction board can advance single-chip microcomputer by burning is the different caution indicator diagram of cyclic transformation in order, thereby realize the function of multinomial caution indication, saved the input cost of user's locality facility, simultaneously, this dynamic process of conversion different caution indicator diagram has more been strengthened LED caution direction board caution indicating effect, is beneficial to the pedestrian and early finds the caution indicator signal.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that device of the present utility model connects block diagram.
Embodiment
A kind of LED caution direction board as depicted in figs. 1 and 2 comprises support bar 1 and the casing 2 that is located on the support bar 1, and this casing 2 is made of cold rolling iron plate.The casing internal fixation is provided with pcb board 3, control circuit 4, control panel 5.Described pcb board 3 connects control circuit 4 by lead, and control circuit 4 leads connect control panel 5.Described control panel 5 is provided with power switch 51.
Arrange on the described pcb board 3 and be fixed with LED assembly 6, these LED assemblies 6 permutation and combination on pcb board 3 becomes multiple caution indicator diagram.In the present embodiment, described LED caution direction board is mainly used in the place, refuelling station, so LED assembly 6 permutation and combination become three kinds of caution indicator diagrams, as shown in Figure 1, promptly prohibits fiery pattern, speed limit pattern, horn-blowing control pattern.Certainly, in other occasion, can be transformed into the required caution indicator diagram of other occasion.
Comprise single-chip microcomputer 41 in the described control circuit 4, burning has program in the single-chip microcomputer 41, and this program can be warned the automatic control in direction board energising back LED caution direction board at LED and show the caution indicator diagram with time interval conversion in order.
The box mouth 21 of described casing 2 is provided with transparent cover plate 22, and in the present embodiment, the material of this transparent cover plate 22 is a tempering Nano self-cleaning glass, and the fitted seal filler rod with above-mentioned device once sealing in casing.
Above-mentioned only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some distortion and improvement, these also should be considered as belonging to protection domain of the present utility model.
