Description

 The device magnetically controlled blinker board refers to the means of display and indication of information. It can be used to create information fields with on-off information carriers such as blinkers for information displays, flat screens, pointers, etc.

 The above tools relate to the nodes of information systems.

 In this case, the main factor affecting the cost of an information system is the frequency of information change, therefore, when developing these systems, when choosing its components, it is advisable to divide information into three groups: operational (rapidly changing), periodically and rarely changing.

 For rapidly changing (operational) information, the frequency of change of which is from seconds to several hours, dynamic systems with any kind of indicators are used. Examples of information systems with a quick change of information are electronic clocks, a train departure board, etc.

Information display system data can be classified according to the type of display elements (in decreasing power consumption):
accumulation lamps, gas discharge lamps, cathode ray tubes, LEDs, liquid crystal indicators, blinker devices.

 This proposal relates to the development of blinker indicating devices.

Blinker devices according to the design of display elements can be divided into the following modifications:
- flipping, i.e. each familiarity or line consists of a set of plates with plotted graphic information and scrolling is performed to display the necessary information. Currently, they are rarely used due to complex mechanics, cumbersomeness and, as a consequence, high cost.

 - systems using non-magnetic blinkers with elements of soft magnetic material, for example, the system of the English company "Brigt tech developments LTD".

 - systems using blinkers made of hard magnetic material or non-magnetic with elements made of hard magnetic material.

 Currently, well-known companies usually produce magnetic memory systems, i.e. The core of the control coil of the blinkers is remagnetized depending on the polarity of the control pulse, which forcibly keeps the blinker in the set position. These are the most commonly used display elements used by firms producing information systems. If you do not take into account the different shape and size of the blinkers, you can distinguish three main designs of display elements.

 Blinker rotating around a vertical axis (US patent 3668699, class G 08 B 5/24, 1972).

 Flat blinker according to the size of an information element, rotating around a vertical axis coinciding with its axis of symmetry (SU, copyright certificate, 437118, class G 08 B 5/24, 1974).

 A flat blinker, half the size of an information element, rotating around a vertical axis coinciding with one of its sides. This is the most common version produced, for example, by the Hungarian company FOK-DIEM (VISINFORM system), the German company KRUEGER, the French companies AEG and LAWO, etc.

 For periodically changing information, the frequency of the shift is once a day - a week, a blinker system is used on seven-segment digital indicators with a manual change of information. For example, such systems are produced by the Hungarian company "FOK-DIEM" for a quote board for the value of currencies or a board for the cost of gasoline at gas stations. These systems are much cheaper than dynamic systems with a slight deterioration of the operator’s working conditions.

 For rarely changing information, the frequency of change of which is from once a week or less, static systems are used. For example, graphic information in the form of diagrams, posters, announcements, etc.

 The closest in technical essence to the claimed magnetically controlled blinker scoreboard, is the device scoreboards described in US patent 4015255, CL. G 08 B 5/24, 1977.

 Known magnetically controlled blinker display contains a panel on the outside of which are magnetically controlled display elements. The electromagnetic control elements are connected to the position setting unit of the magnetically controlled display elements. The electromagnetic control elements are a single core, protruding to the side of the panel, the core on which the excitation winding is located. When a current flows in the latter, a magnetic field arises at the end of the rod, the polarity of which is determined by the direction of this current. Opposite each core is mounted a permanent magnet of the indication element, the axis of which passes between the opposite magnetic poles. Means are provided for turning the permanent magnet around an axis passing between the poles in the transverse plane of the panel, with the axis of rotation parallel to the plane of the panel. When current flows in the excitation winding of the electromagnetic control element from the positioning unit of the magnetically controlled display elements, the field that appears at the end of the specified control element interacts with the permanent magnet field of the display element, causing the latter to rotate around the axis. As a result, one of the poles of the permanent magnet is placed opposite the corresponding end of the core core of the electromagnet. Contrast coatings are applied to opposite surfaces of the magnetically operated display element. The element is mounted on a permanent magnet and rotates with it. As a result, one of the contrasting surfaces will face the observer.

 Known blinker systems, including the closest analogue, have the following disadvantages.

 Blinker systems with quick change of the displayed information on the basis of blinkers made of hard magnetic material or non-magnetic with elements made of hard magnetic material contain a positioning unit and a complex automatic control circuit for each blinker.

 Known designs of magnetically operated blinker displays are bulky and due to the large number of electromagnetic controls (their number is equal to the number of familiarity on the display) is unreliable in operation.

 The technical result of the proposal is the creation of a magnetically controlled blinker board with a semi-automatic control mode, which reduces the number of electromagnetic control elements. Due to this, the cost of equipment is reduced, the installation time of the board in a given place of information display is significantly reduced, for example, on moving objects or as a shift advertisement.

 This design does not require installation of communication cables.

 By changing the design and arrangement of magnetically controlled elements, it is possible to change information both with front access and from the back of the display panel.

 One of the qualities of this design is almost any thickness of the display panel to the smallest, because it depends only on the thickness of the magnetically controlled display elements.

 The technical result is achieved by the fact that in a magnetically controlled blinker display panel containing a panel, on the external side of which there are magnetically controlled display elements, electromagnetic control elements associated with the position setting unit, magnetically controlled display elements, electromagnetic control elements are placed in the housing, the working panel of which is made of non-magnetic material with a number of holes for placement of electromagnetic controls with the possibility of interaction, with magnetically controlled and indication elements when moving the case from the outside of the panel.

 The drawings show preferred embodiments of a magnetically controlled blinker board.

 In FIG. 1 is a functional diagram of a device comprising a panel 1, on the outside of which there are magnetically controlled display elements 2 (blinker), a housing 3 of electromagnetic control elements 4 connected to a position setting unit 5 of magnetically controlled display elements 2. This figure illustrates an embodiment of a device with a mode for controlling the position of magnetically controlled display elements from the front of panel 1 of the panel.

 In FIG. Figure 2 shows an example of a device with a mode for controlling the position of electromagnetic indication elements on the reverse side.

 In FIG. 3 shows an example of the structural placement of electromagnetic control elements in the housing 3 and connecting them to the unit 5 for setting the position of the magnetically controlled display elements. On the working panel 6, holes 7 are made of non-magnetic material of the housing for accommodating the working ends of the electromagnetic control elements 4, a motion sensor 8 is installed on the surface of the housing 3, designed to synchronize the operation of the electromagnetic control elements 4 and the position setting unit 5 of the magnetically controlled display elements.

 In the housing 3 to accommodate the electromagnetic control elements 4 includes the required number of these elements. For example, with a row height of 8 magnetically controlled display elements 2 (blinkers), 8 electromagnetic control elements 4 are included. This number does not depend on the number of blinkers 2 located along the length of the panel, forming a line.

 The housing 3 may be provided (not shown) with a device for mechanical movement along the line, for example, in the appropriate directions (not shown).

 When manually moving the device to move the housing 3 may not be.

 A movement sensor 8 is installed on the housing, designed to synchronize the operation of the electromagnetic control elements 4 and the unit 5 for setting the position of the magnetically controlled display elements.

 Each control element 4 is connected through a wire 9 to the unit 5.

 Depending on the convenience of access to the scoreboard, there are two options for performing the scoreboard: for changing information from the back. The front and back sides of the panel will be external in relation to the placement of the housing 3 of the electromagnetic control elements both in the erase mode and in the recording mode.

 On the scoreboard in the simplest case, one set of electromagnetic controls located in the housing 3 is required.

 The unit 5 for setting the position of the magnetically controlled display elements is, for example, a register 9 (not shown) synchronized by a displacement sensor 8, each bit of which is associated with a corresponding control element 4.

 Code signals (0,1) come, for example, from a memory unit (not shown in the drawing) in parallel to the register. Each code signal, for example, of 8 characters, is synchronously recorded in the corresponding register bit. This occurs in the time interval passing over the column that corresponds to the next pulse of the displacement sensor.

 Thus, each column of the scoreboard, for example, of 8 blinkers will change its state when 8 electromagnetic elements are placed in the zone of their operation located in the housing 3, the location of which corresponds to the location of the blinkers in the column, for example, an 8-digit scoreboard.

 As the case 3 with elements 4 moves, the entire row of the scoreboard of 8 blinkers (bit) columns will change its information state.

 Magnetically controlled blinker board works as follows.

 The panel is a panel 1 with magnetically controlled indication elements and removable protective glass 10 installed on it with blinkers. The glass, in addition to the protection function, performs the function of fixing the blinker elements (not shown in the drawing).

 When working with a magnetically controlled device remove the protective glass 10 from the scoreboard. The case 3 is installed to place the electromagnetic control elements at the beginning of the line and connect elements through the wires 9, for example, by means of a switch (not shown in the drawing) to the unit for setting the position of magnetically controlled display elements. Turn block 5 into the erase mode of previously recorded information. For example, in the register of block 5 in this mode, “0” is written in all digits. Move the housing 3 with electromagnetic control elements 4 to the end of the line.

 During this operation, all magnetically controlled display elements 2 (blinkers) are switched to the zero position and the information field of the board becomes, for example, black.

 Then, the case with the electromagnetic control elements is returned to their original position.

 In general, this is not necessary, because for the sensor 8 displacement any extreme position of the electromagnetic elements on the scoreboard can be taken as the starting position.

 The unit 5 for setting the position of the magnetically controlled display elements is turned on in the recording mode and the housing 3 with the elements 4 is moved to the end of the line. During this operation, the blinkers 2 are switched in accordance with the recorded information.

 Then remove from the panel 1 the housing 3 of the electromagnetic control elements and install a protective glass on the scoreboard.

 The proposed design of a magnetically controlled blinker board can be used to indicate, for example, the route of movement of vehicles (buses, trolleybuses, minibuses, trams), which varies depending on the route number, time of day, etc.

 Since the proposed display is convenient to operate, and its size can vary within a given, practically any range, the display can be used for any advertising purposes.
