Description

Rotating information device.

The proposed utility model relates to information technology and can be used to create devices for displaying advertising and cognitive information.

Rotating information devices are known, the distinguishing feature of which is the ability to create large-format images using a set of light emitters. So, it is known the Turn Sign according to the patent of Russia No. 2103750, MKP G09F 11/00, 1998, in which sets of single image elements are assembled in blocks located in cells of a rectangular farm and forming together an information field. The truss is mounted vertically and by means of a slewing ring device can slowly rotate around a vertical axis by 360 degrees, which increases its visibility. The main disadvantage of such a panel is its high cost due to the large number of image elements equal to the product of the number of elements in a row by the number of lines.

This drawback is overcome in a number of known information devices in which only one or several lines with light emitters quickly rotate around a vertical axis, forming an information field. The effect is based on the peculiarities of the human visual memory, which retains an image that has already disappeared for some time, as a result of which a rotating line of light emitters creates two- and three-dimensional spatial pseudo-images that are perceived as real.

So, it is known Electromechanical display according to the patent of Russia No. 2172983, MCP G09F 9/30, 2001. It contains grouped in triads LEDs (red-green-blue), placed on the outer periphery of the petals of the rotor rotating with a sufficient angular speed, resulting in multi-color images on pseudo-surfaces. Unfortunately, the shape of the petals of this device is chosen so that one of the important visual effects achieved in other similar devices disappears: the illusion of the image in the air without visible support.

This lack of rotating information device according to the application of Germany No. 19630011, G09F 9/33, 1996 In it, on a disk rotating in a horizontal plane, one or several vertical rods are mounted on which light emitters are mounted. The light emitter control unit is fixed motionless, and the luminescence control signals from it are transmitted individually to each light emitter through movable electromagnetic or optoelectronic connections. The disadvantage of this known device is its high cost due to the large number of these technically complex compounds. This limits the very number of light emitters and, thus, the amount of information displayed.

INCG09F 9/33

The closest in technical essence analogue of the proposed utility model is the rotating information device described in Russian patent No. 2159962, cl. MKP G09F 9/33, 19/00 and G09G 3/00, 2000, according to the application No. 2000105805/12 of 03.13.2000. It contains (see Fig. 1) a housing 1, a rotating motor 2 with a bearing shaft 3, a balancing holder 4, a rotating indicating unit 5, including at least one arm 6 with holders 8 and 9 for attaching the light emitters 10 and block 11 the control of light emitters, having separate control circuits for each of them, fixedly connected to their inputs, and a power supply 12, fixed motionless in the housing I and connected to the control unit 11 of the light emitters through movable electrical contacts 13 and the contact sleeve 14. The bracket 6 includes ment 7 and at mensche least two holder arranged thereon light emitters 8 and 9, different distance from the rotation axis and forming two rotational bodies representing information surface. The bracket 6 is fastened to the shaft 3 through the balancing holder 4.

The control unit 11 of the light emitters comprises a storage device 17 connected to the block of output registers 19 and to a central processor 18, connected by its output to the block of registers 19, and the input to a circuit 20 for linking the beginning of the sweep, consisting of a stationary emitter 21 and a movable receiver 22. Block 23 provides stabilized power to the electronics of the rotating display unit 5, receiving the primary voltage itself from the power supply unit 12 through the sliding electrical contacts 13 and the contact sleeve 14. The engine 2 has a soft suspension 1 5. The block of output registers 19 with its outputs is element-wise connected to the light emitters 10.

When the power is turned on, the engine 2 starts to rotate and through the shaft 3 and the holder 4 transmits rotational motion to the display unit 5, which, by rotating its bracket 6 with holders 8 and 9, forms a spherical and cylindrical surface of rotation of the light emitters 10. To give these surfaces informational properties, the unit power control 11, receiving power supply through the circuit: power supply 12 - movable contact pair 13,14 - stabilized power supply 23. All information about the image is stored in a storage device (Memory) 17.

The information fields are divided into vertical sectors, in each of which the columns of light emitters 10 alternately turn out during rotation. One sector, in which the emitter 21 of the scanning start linking circuit 20 is located, is synchronizing (first). When the receiver 22 passes by the stationary emitter 21, a pulse of the beginning of the sweep start is generated in the receiver 21, by which the processor 18 extracts from the memory 17 information about the required state of the light emitters for the first sector (lit - not lit) and puts it in the block of output registers 19, directly controlling each light emitter 10 during the passage of this sector Tc 1 / FN, where F is the rotation frequency and N is the number of image sectors. After Tc, the processor 18 likewise proceeds to control the luminescence of the light emitters for the 2nd sector, after 2Tc for the 3rd sector, etc., alternately for all sectors of the information fields. The rotation of the display unit 5 with light emitters 10 occurs at a high angular velocity (20 ... 25

r / sec), sufficient to create a stable, unblinking image of information in the eyes of the observer and, at the same time, the apparent disappearance of the holders, which provides the visual effect of the presence of a visual image in the air without visible support.

The disadvantages of this well-known technical solution include the following;

1. The power supply to the rotating display unit 11 is supplied through the sliding electrical contacts 13 and the contact sleeve 14, which entails certain inconveniences in operation: the need for cleaning and periodic replacement of electrical contacts, the effect on the electronic circuits of interference from sparking of contacts, etc.

2. Changing the displayed information is done either by physical replacement of the storage device 17 (usually a ROM with ultraviolet erasure), or by applying special signals through the processor 18 for recording on the memory 17,

Both disadvantages require a periodic stop of the rotating display unit 11 and direct access to it by maintenance personnel. This is especially inconvenient when, in order to expand the field of view, the information device is placed on special towers, so that the staff would have to work at height.

The objective of the proposed technical solution is to increase the usability and reliability of the device by eliminating the noted drawbacks.

The essence of the proposed utility model is that in a rotating information device comprising a processor and a supporting housing with an electric motor mounted on it with a shaft connected through a balancing holder to a rotating display unit containing light emitters and at least one bracket with a holder for mounting of light emitters, a control unit for emitting light emitters, comprising a decoder connected by its output to the input of the register, the outputs of which are element-wise coupled to the light emitters firs, and the stabilized power supply, the output of which is connected to the power inputs of the decoder, register, and emitter of the scan start binding circuit, which also has a receiver, made structural changes, namely, it introduced a wireless communication channel, a high-frequency generator located in the support case, and two windings, movable and fixed, coaxially located on a ferrite tube mounted on the motor shaft, while the fixed winding is connected to the output of the high-frequency generator, and the movable to the input stabilized power supply unit, the processor is located outside the rotating unit and its synchronization input is connected to the output of the scan start binding circuit fixed to the receiver support housing, and the processor output is connected to the decoder input via a wireless channel.

A comparative analysis of the claimed technical solution with the closest analogue shows that its new significant differences from the known technical solution are as follows:

1. Introduced movable and fixed windings coaxially located on a ferrite tube mounted on an electric motor shaft, and high-frequency

a generator located in a support housing. In this case, the fixed winding is connected to the output of the high-frequency generator, and the movable winding is connected to the input of the stabilized power supply.

2. A wireless channel is introduced with its input connected to the output of the processor located outside the rotating display unit, and the output to the decoder input.

3. The emitter of the reference circuit for the beginning of the sweep is located on the rotating display unit and connected to the output of the stabilized power unit, and the receiver of the reference circuit is located on the supporting case and connected to the processor synchronization input |

The proposed technical solution is new, original and non-obvious, since the analysis of known ones. solutions in the information and related fields of technology did not reveal anything like that.

The following is an example of the implementation of the proposed technical solution, showing its industrial feasibility1 The drawings correspond to;

FIG. 2 - drawing of the device in the installed state,

FIG. 3 - created information surface.

The proposed rotating information device (see FIGS. 2 and 3) comprises a support housing 1, a high-frequency generator 24 mounted thereon, an electric motor 2 with a shaft 3, on which a ferrite tube 25 is mounted, which serves as a magnetic circuit for the stationary 26 and movable 27 coaxially located on it windings, balancing holder 4, through which the shaft 3 is mechanically connected to a rotating display unit 5, containing a bracket 6 with a holder 8 for attaching the light emitters 10 and a shielded light emitter control unit 11, comprising decryptor 28, register 19, emitter 21 of the start-of-reference binding circuit 20 and the stabilized power supply 23. The processor 18 can be located in the support housing 1 or outside it, for example, in the user's office. The electric motor 2 is attached to the supporting body 1 through the shock absorbers 15. The movable winding 27 is mechanically connected to the balancing holder 4, and the stationary winding 26 is connected to the housing 1. On the housing 1 is also a receiver 22 of the scan start binding circuit 20. Between the processor 18 and the rotating block 5 wireless channel 29 is operational.

The following electrical connections are provided in the device: The output of the high-frequency generator 24 is connected to the fixed winding 26, the movable winding 27 is connected to the input of the stabilized power supply 23, the output of which is connected to the power inputs of the electronic nodes 19, 21 and 28. The output of the decoder 28 is connected to the input of the register 19 the outputs of which are element-wise coupled to the light emitters 10. The synchronizing input of the processor 18 is connected to the output of the receiver 22, and the output of the processor 18 is connected to the input of the decoder via a wireless channel 29 28.

The binding circuit of the beginning of the sweep 20 may be, for example, an optical pair of an LED (emitter) - a photodiode (receiver). Wireless channel 29 may be implemented in various ways:

a) in the form of an optical pair, similar to the binding circuit 20, in which the LED and the photodiode are located on the axis of the shaft 3, the LED connected to the output of the processor 18, and the photodiode to the input of the decoder 28;

b) by organizing a low-power radio channel, the transmitter of which is connected to the output of the processor 18, and the output of the receiver to the input of the decoder 28;

c) by frequency or other modulation of the high-frequency radiation of the generator 24, while the modulation input of the generator 24 is connected to the output of the processor 18, and the movable winding 27 is additionally connected to the input of the decoder, which is given additional demodulation functions.

Rotating information device operates as follows. After turning on the power, the rotor of the electric motor 2 starts to rotate, and its rotation through the shaft 3 and the balancing holder 4 is transmitted to the bracket 6 of the display unit 5, the holder 8 of which together with the light emitters 10 form some rotation surface (cylinder, ball, ellipsoid, etc.), serving to post information. Surfaces can be one or more, depending on the shape, quantity and relative position of the holders 8 relative to the axis of rotation. In this example, the simplest cylindrical shape with one holder was used.

The high-frequency signal of the generator 24 enters the stationary winding 26 and excites high-frequency electromagnetic oscillations in it, passing through the ferrite tube 25 and also penetrating the movable winding 27. The high-frequency voltage introduced in the latter enters the stabilized power supply 23, where it is rectified, stabilized and serves to power electronic nodes of a rotating display unit 5: decoder 28, emitter 21, register 19 and, through the register, light emitters 10.

With the passage of the luminous emitter 21 near the receiver 22 of the reference circuit of the beginning of the sweep 20, the pulse of the beginning of the scan image is fed to the clock input of the processor 18. The time interval T between pulses coming one after the other from the emitter 21 located on the holder 8 serves to generate the time Tz of the illumination of the light emitters 10, which refers to one sector (column) of the decomposition of the Tz T: N image, where N is the number of sectors on the information surface. The time interval T is constantly counted by the processor 18 using its timer and, thus, is adjusted at each revolution. This avoids image overlays in case of instability of the speed, caused, for example, by changes in the frequency and voltage of the network.

Upon the arrival of each scan start pulse, the processor 18 turns to its storage device, where all image information is stored, and selects the part related to the first decomposition sector. From the processor 18, the selected information is transmitted in a certain sequence through the wireless communication channel 29 to the decoder 28, and from it, divided by image elements, to register 19, where it is held for a time T3, providing illumination or lack of illumination of the corresponding light emitters 10 related to the 1st sect yelling images. After the exposure time T3 expires, the processor 18 selects information related to the 2nd sector from the storage device and likewise provides the illumination or absence of illumination of the light emitters 10 of this decomposition sector, etc., for the 3rd, 4th ... N-ro sectors, until the rotating display unit 5 makes a full revolution and near the receiver 22 of the reference circuit of the beginning of the sweep 20, the emitter 21 again appears.

Thus, in one revolution, an image of the entire information surface is formed, after which the process is repeated, ensuring that the emitters of the light emitters 10, for example, 25 l / ceK, are fast enough so that there is no flicker at a rotation speed of 25 r / sec.

In FIG. 3 shows an example of the formation of an elementary image of information during operation of the proposed information device. The light emitters 10 located on the holder 8, while rotating the display unit 5, describe circles that are folded into a cylindrical information surface divided into N sectors 30 and M of rows 31. The number M is equal to the number of light emitters 10 on the holder 8. When a single light emitter is illuminated on the information surface there is a bright luminous dot (stroke), which is the minimum element of the image. In the absence of illumination, a non-luminous spot forms, which in contrast appears black. The entire image is built from combinations of such bright and dark dots.

Any information — a running line, a graphic image, or combinations thereof — is created using special software and stored in the memory of processor 18. Image is changed using processor 18, in the simplest case, from its diskette, but all known means of exchange can be used information: local area networks, the Internet, etc. To change the information does not need to stop the display unit 5.

The information image can be either monophonic or color, if applied to each point of the triad of light emitters 10 (red, green, blue). At the same time, the storage capacities of the processor 18, the decoder 28, the register 19 and the light emitters 10 increase, and the programming becomes more complicated, but the capabilities of the device expand.

The information device can be implemented on the basis of well-known, commercially available elements and materials, so that there is no doubt about its industrial feasibility.

The proposed technical solution has the following advantages compared to the closest analogue:

a) replacement of the displayed information is made without direct access to the rotating display unit and without stopping it, which is especially important for information devices located high above the ground;

b) sliding power contacts are not used to power the rotating information block, which simplifies operation and increases the reliability of the device;

c) the use of a processor located outside the rotating unit allows the use of modern means of information exchange for its task and operational change, including in the form directly determined by the customer.
