Description

Intelligent real-time automatic sheltered billboard

technical field

The invention relates to a billboard, in particular to a billboard that can automatically avoid wind in real time. The billboards include: billboards on highways, billboards on high-rise buildings in cities, billboards on the top of power or communication towers or on towers, billboards on buildings and everything that may be windy due to its installation location. The flow, and thus wind flow, creates billboards that are detrimental to the billboard body and its supporting structure.

Background technique

Billboards are everywhere, wherever there are people moving. In order to highlight the advertising effect of billboards, billboards are often installed in a high place that is easy to observe. The size of the billboard determines the weight of the billboard itself. And the advertising effect usually wants the bigger the billboard size, the better.

However, since the billboards are generally at high places, when the wind speed is high, due to the size of the billboard itself, a lateral thrust is generated on the billboard body and the structure supporting the billboard, thereby producing safety for the billboard and the supporting structure. hidden danger. In order to ensure the safety of the billboard and its supporting structure, it is often only possible to make the supporting structure very large and strong, thereby causing an increase in the overall weight and cost of the billboard and the supporting structure. In some cases, the overall weight cannot be increased: like billboards on the roof, because the structure of the roof cannot be changed, the weight that the roof can bear is limited.

Therefore, the consequences of the safety hazards generated by the billboard being pushed by the wind are:

1) Sacrificing the size of the billboard, thereby sacrificing the advertising effect;

2) increase in overall weight;

3) Reinforcement of billboards and supporting structures, resulting in increased overall cost and increased installation difficulty;

4) In some installation situations, the problem cannot be solved by strengthening the overall structure and increasing the overall weight.

To solve these problems, an intelligent billboard structure is the key to solving the problem.

SUMMARY OF THE INVENTION

The technical solution adopted by this patent to solve its technical problems is: an intelligent real-time automatic wind-proof billboard, including billboard frame, display curtain, curtain driving component, display curtain roller, display blade, blade driving component, wind sensor, wind direction Sensors, shock sensors, light sensors and billboard controllers.

There are two display schemes for the above-mentioned intelligent real-time automatic wind shelter billboard: A display screen scheme, and B display blade scheme. The display curtain is installed in the billboard frame, and the curtain driving component is installed on the billboard frame. The display curtain is rolled up and down or horizontally through the display curtain roller to form a display curtain scheme; the display blade is installed on the billboard frame through the blade drive component. It is installed vertically or horizontally to form a B display blade scheme; the billboard controller is installed on the billboard frame.

In the above-mentioned intelligent real-time automatic wind-proof billboard, the above-mentioned display screen scheme A is to hollow out the display screen by rolling up the screen when the wind exceeds the safe range, thereby reducing the windward surface. The B display blade scheme reduces the windward surface by rotating the windward angle of the display blade when the wind exceeds the safe range.

In the above-mentioned intelligent real-time automatic wind shelter billboard, the blade drive assembly is composed of a blade rotating shaft, a motor + a transmission, an electromagnetic clutch, a blade position sensor and a blade bearing. The blade drive assembly is mounted on the billboard frame.

The electromagnetic clutch is coupled when powered and disengaged when powered off. In the coupled state, the motor can drive the display blade, and in the disengaged state, the display blade can passively freely rotate around its own blade rotation axis. When the electromagnetic clutch loses power, whether it is a control loss or a mains loss, the electromagnetic clutch automatically disengages the motor + the transmission and the blade rotating shaft by gravity.

The above-mentioned B display blade scheme, the drive of the display blade is jointly driven by a motor + transmission to drive all or more blade rotating shafts, each display blade is equipped with a synchronous pulley on the blade rotation shaft, and each display blade is connected with Adjacent display blades are connected by a timing belt to form a common drive mode; or a motor + transmission drives a blade rotating shaft independently to form a separate drive mode.

The above-mentioned scheme B shows the blade scheme. The windward angle of the rotating display blade is driven by the motor + transmission, and the wind direction is determined according to the feedback of the wind direction sensor, and the display blade is automatically rotated and adjusted so that the windward surface of the display blade is Minimum ( 7 ). Or the windward angle of the rotating display blade is to disengage the motor + transmission and the blade rotating shaft through the electromagnetic clutch, so that the display blade can be passively rotated freely under the action of the wind, so that the windward surface of the display blade is automatically adjusted to the minimum.

In the above-mentioned intelligent real-time automatic windproof billboard, the display curtain is made of materials that can be rolled, such as cloth, chemical fiber film, etc.; the size of the curtain is not larger than the size of the billboard frame.

In the above-mentioned intelligent real-time automatic windproof billboard, the curtain driving component is composed of a motor and a winding wheel; the driving component is installed on the billboard frame.

In the above-mentioned intelligent real-time automatic windproof billboard, the display blades are made of aluminum alloy or fiber sheet, and each blade is installed vertically or horizontally; The rotating shaft of the blade is asymmetric in the position of the display blade, and is close to the front end of the display blade, and the rotating shaft of the blade is installed on the frame of the billboard.

In the above-mentioned intelligent real-time automatic windproof billboard, the wind sensor, wind direction sensor, vibration sensor and photosensitive sensor are installed on the billboard frame and connected with the billboard controller. The billboard controller accepts the feedback from the wind sensor, the wind direction sensor and the vibration sensor, calculates the magnitude of the wind power according to the signals of the wind sensor and the wind direction sensor, and folds or folds the billboard according to the vibration magnitude measured by the vibration sensor. Adjust the windward angle action; the feedback from the photosensitive sensor can be used to limit the content switching of the billboard or turn on the lights at night.

In the above-mentioned intelligent real-time automatic windproof billboard, the billboard controller is composed of a single-chip microcomputer. Its functions are: real-time monitoring of wind, wind direction and vibration. When the wind is within a safe range, roll the curtain or turn the display blades to switch the advertising content; when the wind exceeds the safety range, retract the display curtain to make the curtain partially hollow, or rotate the display blades to minimize the windward angle of the display blades. The billboard controller includes the following functional units: power supply, sensor input, motor drive, electromagnetic clutch drive, MCU, communication unit, and LED display.

The beneficial effects of this patent are: the billboard controller measures the wind speed, wind direction and vibration in real time, and when the measured value exceeds the safe range, the billboard's windward display area is minimized through the A display screen scheme and the B display blade scheme. Among them, the A display screen scheme can reduce the area to zero, and the B display blade scheme can not reduce the windward surface to zero, but can complete the minimization of the windward surface in a very short time. In particular, the passive free rotation function in the B scheme can ensure that the windward surface is minimized in the event of a power failure of the entire billboard system, and the response speed is the fastest among all schemes.

When the wind speed is within the safe and safe range, the billboard maintains the display function of ordinary billboards through the A display screen scheme and the B display blade scheme: switching multiple advertising contents.

Through this patented technology, billboards can be installed on structures that were previously unable to install billboards. Larger billboards can be installed on structures that previously could only be installed with relatively small area billboards. Many places where billboards cannot be installed due to high or rapidly changing wind speeds have the potential to install billboards. Also, the weight of the billboard is lighter than that of a normal billboard.

Detailed ways

As shown in Figure 1 A shows the implementation of the curtain scheme. The display part of the advertisement is composed of two upper and lower display curtain rollers 25 and a display curtain 2 (it may also be two left and right display curtain rollers 25 ). The upper display screen roller 25 is driven to rotate by the screen drive assembly 3, and the screen drive assembly 3 can rotate forward or reverse to change the content of the advertisement display part. The advertisement display section changes content at preset time intervals.

In FIG. 3 , when the wind force sensor 10 and the wind direction sensor 11 detect that the wind force on the windward side is greater than a preset value, the upper display curtain roller 25 rotates to retract the display curtain 2, so that the display curtain 2 in the billboard frame 1 is rotated. The area is hollowed out to minimize the windward side, so as to protect the billboard and the structure that supports the billboard. When the wind power returns to a safe range, the display curtain roller 25 releases the display curtain 2 to restore the advertising function.

B as shown in Figure 2 shows the blade scheme implementation. The scheme is completed by showing the blade 4. Allocate the entire advertising area to several display blades 4 . Under normal circumstances, the wind power is within the safe range, and each display blade 4 is displayed either on the front (0 degrees) or on the reverse side (180 degrees).

When the wind force exceeds the safe range, as shown in FIG. 4 , the display blades 4 start to rotate, so that the windward surface of each display blade is minimized, so as to protect the billboard and the structure supporting the billboard. When the wind power returns to a safe range, the display blade 4 is rotated to a position of 0 degrees or 180 degrees, and the advertising function is restored.

As explained above, when the wind force exceeds the safe range, the function of displaying the rotation of the blades 4 to keep the windward surface to a minimum is accomplished by two methods:

The first method is: when the wind force exceeds the safe range, the wind direction is determined according to the feedback of the wind direction sensor 11 , and the windward angle of the display blade 4 is adjusted to minimize the windward surface of the overall display blade 4 . Under this method, it is shown that the blade 4 is directly driven to rotate by the motor+transmission 6 through the blade rotating shaft 5 . The rotation of the blade rotation shaft 5 is automatic rotation.

The second method is: when the wind force exceeds the safe range, the connection between the motor + transmission 6 and the blade rotating shaft 5 is disengaged through the electromagnetic clutch 7, so that the display blade 4 is driven by the wind force to passively rotate freely. As shown in FIG. 5 , because the section of the display blade 4 is a streamlined structure and the asymmetrical arrangement of the blade rotation axis 5 , the final result is that the display blade 4 is passively free to rotate under the action of the wind, so that the windward surface is minimized. In this case, the windward side of each display blade 4 can be kept to a minimum. The rotation of the blade rotation shaft 5 is passive free rotation.

The difference between the first method and the second method is whether the cooperation of the motor + transmission 6 and the blade rotating shaft 5 is directly driven (without the electromagnetic clutch 7 in the middle) or driven by the electromagnetic clutch 7 . The first method relies on the detection of the wind direction sensor 11 when adjusting the windward angle. The second method may not rely on the detection of the wind direction sensor 11 . The advantage of the second method is that the billboard maintains a minimum windward side even if the billboard loses power.

There are two methods for driving the blade rotating shaft 5 by the motor+transmission 6: one motor+transmission 6 drives the blade rotating shaft 5 separately (single drive), and one motor+transmission 6 All the blade rotating shafts 5 are driven (co-driven).

As shown in FIG. 7 , a timing belt pulley 22 is installed on the blade rotating shaft 5 of each display blade 4 , and each display blade 4 is connected with the adjacent display blade 4 by a timing belt 23 . Under this connection, all the display blades 4 become a whole and rotate synchronously. As long as the motor + transmission 6 drives one of the display blades 4, the whole can be driven. After the motor+transmission 6 is disengaged from the vanes through the electromagnetic clutch 7, the entire display vanes 4 are passively and freely rotated together. Due to the limited size of the figures, the distances between the blades in the figures are not drawn to scale.

FIG. 6 shows the structure of the blade drive assembly 24 . An electromagnetic clutch 7 , a vane position sensor 8 and a vane bearing 9 are installed on the vane rotating shaft 5 . The role of the electromagnetic clutch 7 is to disengage and couple the connection between the motor + transmission 6 and the blade rotating shaft 5 . The function of the vane position sensor 8 is to detect the angle of the present display vane 4 .

Once the motor + transmission 6 is disengaged from the blade rotating shaft 5, in the next coupling process, if it is driven together, just adjust the angle of the display blade 4 to 0 degrees or 180 degrees to restore the display function of the billboard. If it is driven independently, the display function of the billboard can be restored by adjusting the corresponding display blades 4 of each motor + transmission 6 to 0 degrees or 180 degrees.

The above "single drive" and "joint drive" are not absolute. For example, in the case of a total of 10 display blades, every two blades are used as a group, and the two blades are "commonly driven", then there are 5 "individually driven" units in the entire advertising system, and 5 Motor + transmission 6.

As shown in FIG. 8 , a wind sensor 10 , a wind direction sensor 11 , a vibration sensor 12 , a light sensor 13 and a billboard controller 14 are installed on the billboard. The function of the wind sensor 10 is to measure the real-time wind speed. The function of the wind direction sensor 11 is to measure the real-time wind direction. The function of the shock sensor 12 is: when the billboard starts to shake under the action of any external force (including wind), the billboard can be collected, and at the same time, it can alarm the upper system.

A functional block diagram of the billboard controller 14 is shown in FIG. 9 . The billboard controller 14 is a unit installed on the billboard frame 1 to control the entire billboard in real time. Including: power supply 15, sensor input 16, motor drive 17, electromagnetic clutch drive 18, MCU19, communication unit 20 and LED21 display.

The scope of rights of this patent also applies to products and applications resulting from the modification of the principles and features of this patent.
