Description

A smart warning sign

technical field

The utility model belongs to the technical field of triangular warning signs for automobiles, in particular to an intelligent warning sign.

Background technique

With the development of economy and society and the improvement of people's living standards, the use of family cars is also increasing. However, while enjoying the convenience brought by family cars, it also brings many troubles, such as accidents caused by temporary car failures or other various traffic accidents. Accidents, in order to avoid causing secondary traffic accidents thus, a kind of conventional emergency response device-warning board is usually equipped on the car. The current warning signs are all passive reflective bodies made of plastic reflective materials, and when the owner encounters an accident, the owner needs to place the warning sign at a certain distance behind the car to remind other vehicles to avoid it in time. To avoid secondary traffic accidents, there will be certain safety hazards in the process of placing warning signs by car owners. In order to solve this problem, it is necessary to design an intelligent warning sign that can automatically move and automatically correct the direction.

Contents of the invention

The technical problem solved by the utility model is to provide an intelligent warning sign with simple structure, reasonable design and convenient operation.

The utility model adopts the following technical solutions to solve the above technical problems. An intelligent warning sign is characterized in that it includes a base, a roller disposed on the bottom of the base, a power supply disposed on the base, a single-chip microcomputer, an information storage unit, a first support plate, Roller drive device, direction control device, switch and distance preset button, first ultrasonic range finder, LED display and second ultrasonic range finder, one end of the second support plate is hinged with one end of the third support plate, and the second The other end of the support plate and the other end of the third support plate are respectively hinged to the two ends of the first support plate, fog lamps are respectively arranged on the first support plate, the second support plate and the third support plate, and the first ultrasonic distance measuring The instrument and the second ultrasonic range finder are arranged on one side of the base in parallel, and the single-chip microcomputer is respectively connected with the power supply, the information storage unit, the roller driving device, the direction control device, the switch and the distance preset button, the fog lamp, the first The ultrasonic range finder, the LED display screen and the second ultrasonic range finder are connected.

The utility model has the advantages of simple structure, reasonable design and convenient operation, and can be quickly disassembled and installed. At the same time, the warning sign can automatically drive to the designated position and stop. .

Detailed ways

The specific content of the utility model is described in detail in conjunction with the accompanying drawings. As shown in Figure 1-2, an intelligent warning sign includes a base 1, a roller 2 set on the bottom of the base 1, a power supply 3 set on the base 1, a single-chip microcomputer 4, an information storage unit 5, a first bracket plate 6, Roller driving device 7, direction control device 8, switch and distance preset button 9, first ultrasonic range finder 10, LED display screen 11 and second ultrasonic range finder 12, one end of the second support plate 13 and the third support One end of the plate 14 is hinged, and the other end of the second support plate 13 and the other end of the third support plate 14 are respectively hinged at the two ends of the first support plate 6, the first support plate 6, the second support plate 13 and the third support Fog lamps 15 are respectively arranged on the board 14, and the first ultrasonic range finder 10 and the second ultrasonic range finder 12 are arranged on one side of the base 1 in parallel. , roller driving device 6, direction control device 7, switch and distance preset button 9, fog lamp 15, first ultrasonic range finder 10, LED display screen 11 and second ultrasonic range finder connected 12.

The use process of the utility model is as follows: when the auto parts break down or a traffic accident causes temporary parking, the intelligent warning board needs to work. First, the intelligent warning board is taken out, and the first bracket plate and the second bracket of the warning board Plate and the movable end of the third support plate are snapped together to form a triangular warning sign. Turn on the switch on the base and the distance preset knob to preset the placement distance of the warning sign. At the same time, the first ultrasonic rangefinder and the second ultrasonic The rangefinder stores the first measured distance into the information storage unit, and the two measured distance values may or may not be equal, and then calculate the difference between the two measured distances, and use this difference as the direction reference , the smart warning sign will automatically drive to the rear of the car. During the driving process, the fog lights on the bracket board emit light to warn the vehicles behind to slow down and change lanes in time; if the two measured distances are the same as the direction reference, the smart warning sign is driving in the correct direction, and continue driving until it reaches When the preset distance is reached, stop driving. At this time, the fog lights will light up. If the two measured distances are not the same as the direction reference, the driving direction of the smart warning sign will deviate from the correct direction. This information will be transmitted to the single-chip microcomputer to control the direction control device. Adjust the direction until the measured distance is the same as the direction reference and continue driving until the preset distance is reached, then stop driving, at this time, the fog lights will glow.

The basic principles, main features and advantages of the present utility model have been shown and described above. On the premise of not departing from the spirit and scope of the present utility model, the present utility model also has various changes and improvements, and these changes and improvements all fall into the claims. The scope of the utility model.
