Description

Technical Field

[0001] The invention relates to the technical field of exhibition galleries, in particular to an exhibition gallery display control system. Background Art

[0002] An exhibition hall is a place where information is displayed to the audience. Generally, the items, texts, pictures, etc. to be displayed are arranged on the booths and walls of the exhibition hall. The browsing path of the audience is generally planned by limiting the location of the booths, or the displayed items are placed in the corridor for display in the form of a gallery. With the development of electronic information, the explanatory items such as texts and pictures usually carried by paper are replaced by electronic display screens, making the display method more diversified. At the same time, the display effect can be better adjusted through electronic documents, etc., giving the audience a more comfortable viewing experience. Furthermore, various mechanical structures are used to control the rotation of the display screen to adjust the specific position to show a better display effect, but when it is necessary to Using time as the axis to display the changes in cultural objects, the laws of development of things, the development history of individuals, companies and even countries in different periods, the audience needs to remember the time, events and impacts that occurred in each time period and echo each other. The general display method will cause most viewers to forget the events and their impacts they viewed in the previous time when watching the current event, and when they are forced to remember the specific events they watched last, the audience's energy is all spent on memory, and they cannot invest extra energy into the impact of the continuity of several events, nor can they produce echoes. As a result, this type of display cannot make the audience intuitively feel the impact of an event at a certain time on subsequent events, which leads to limitations in the display effect of this type.

[0003] Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a gallery display control system, which controls the lifting and lowering of display screens and display columns as well as the content information displayed thereon, so that viewers can not only look back and re-understand the content they have viewed previously and combine it with the content they are currently viewing, but also increase viewers' understanding of the nature and content of the currently displayed information through the information, light effects, etc. displayed on the display screens and display columns.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a gallery display control system includes a plurality of display screens, display columns, a driving device for driving the display screens to move, a lifting device for driving the display columns to rise and fall, a feedback device for detecting the position of the crowd, and a controller, and the controller is electrically connected to the driving device, the lifting device, and the feedback device. The plurality of display screens and display columns are evenly distributed on the walls on both sides of the gallery along the direction of the gallery. The driving device drives the display screen to gradually move from a low position close to and parallel to the wall to a high position perpendicular to and away from the wall. The controller receives the signal of the feedback device and controls the movement of the display screen and the display column respectively through the driving device and the lifting device. The feedback device controls the display screen and the display column to display different pictures.

[0006] By adopting the above technical solution, the current position of the viewing crowd is detected by using the feedback device, and then the display screen at the crowd position and several display screens in the crowd's advancing direction are controlled by the feedback device to display the content information required to be displayed at the display screen position, and then the driving device is used to control the movement of several display screens at the current position in the opposite direction of the crowd's advancing direction, that is, the display screen is controlled to gradually rotate from a position parallel to the wall to a position perpendicular to the wall, and also gradually move away from the wall, from a low position to a high position, and the display screen is rotated in a horizontal direction to a direction obliquely downward, so that several display screens far away from the crowd position are always facing the crowd, which is convenient for viewers to look back. The previously displayed information can be directly seen, and then the display column at the current crowd position is driven to rise by the lifting device. At the same time, the feedback device controls the display column to display the corresponding graphic information. As the crowd moves, several display columns at the corresponding positions gradually rise and show different colors. For example, if the current event is exciting, a picture of raging fire can be displayed. If the event is tragic, a corresponding picture of sadness can also be displayed. At the same time, several display columns close to the crowd position show the same picture, while the display columns far away from the crowd and close to the entrance of the exhibition gallery show guidance instructions to guide single people forward, while the display columns far away from the crowd and close to the exit fall to the ground and go out.

[0007] The present invention is further configured as follows: the feedback device includes a first calculator and a plurality of pressure sensors, the pressure sensors are arranged on the floor of the exhibition gallery and a corresponding number is set for each pressure sensor, the force-bearing ends of the plurality of pressure sensors are spliced ​​together to form the floor, the calculator receives the pressure sensor signal and calculates the center position of the concentrated crowd and outputs a signal.

[0008] By adopting the above technical solution, the pressure sensor is used to detect the distribution of the crowd in the gallery, and then the central position of the crowd is calculated by the calculator, wherein the calculation method is:

[0009] The distances along the direction of the exhibition hall along the pressure sensors are taken as the X-axis, and the pressure signals received by the pressure sensors are converted into pressure values ​​as the Y-axis. A point is taken in the middle of the two farthest distance points where the pressure sensors sense pressure, and the corresponding pressure values ​​of the pressure sensors on both sides of the point are multiplied by the distance of the pressure sensor from the middle point. The two sides of the middle point are calculated separately and subtracted (left side minus right side). If the value is within ±1400, the middle point is taken as the center of the crowd. If the calculated value is greater than 1400, the middle point is moved 10CM to the left, and the calculations on both sides of the point are continued and subtracted. If the calculated value is less than 1400, the middle point is moved 10CM to the right, and the calculations on both sides of the point are continued and subtracted. Finally, the center of the crowd is obtained, and then the center of the crowd is converted into a signal input to the controller.

[0010] The present invention is further configured as follows: the controller receives a signal provided by the calculator and drives the display screen and the display column at the corresponding position to move through the driving device and the lifting device at the corresponding position.

[0011] By adopting the above technical solution, the position of each display screen and display column is numbered, and its number represents its distance from the gallery entrance. Then, the crowd position signal received by the calculator is compared with the display screen and display column number. When the data received by the controller is the same as that of one of the display screens and display columns, the position and the display screen away from the gallery exit remain unchanged, that is, the display screen is parallel to the wall, close to the wall, and located at a low position, while the display screen away from the position and close to the gallery entrance moves, and the display screen movement trajectory is divided into five nodes, that is, the display screen moves during the movement. There are five states in the process, which are 0%, 25%, 50%, 75%, and 100% of the entire moving trajectory of the display screen. As the distance between the display screen and the crowd increases, the display screen state gradually changes from the 0% state to the 100% state. When the display screen state changes to the 100% state and the distance continues to increase, the display screen returns to its original state (0% state). When the display screen state changes from the 0% state to the 25% state, the third corresponding display column at the current position close to the gallery exit extends, and when the display screen changes from the 100% state to the 0% state, the display column at this position descends.

[0012] The present invention is further configured such that: the feedback device receives a signal provided by the calculator and controls the display screen and display column at the corresponding position to display different stored information.

[0013] By adopting the above technical solution, when the moving state of the display screen is 0%, the controller controls the display screen to display the detailed information and time of the exhibits at the current position, as well as a detailed explanation, and is accompanied by a picture analysis. When the display screen 15 is in the state of 25%, 50%, 75%, and 100%, the display screen displays rough information, such as a title plus a picture, and summarizes the exhibits at that position. At the same time, as the display screen state changes from 0% to 100%, the size of the font and the image gradually increases, and when several large fonts and pictures cannot be displayed on the display screen, part of the content on the display screen is transferred to another display screen close to the display screen at that position and with a slightly smaller font.

[0014] The present invention is further configured such that: the display column is composed of a plurality of display screens, and the plurality of display screens are perpendicular to the horizontal plane, and the display screens are electrically connected to the calculator.

[0015] By adopting the above technical solution, a plurality of display screens are distributed on the side of the display column, so that viewers can watch the content on the display screen at all angles, further improving the viewing effect.

[0016] The present invention is further configured as follows: the display screens on a plurality of displays and display columns respectively form sorting labels, the controller compares the relationship between the calculator input signal and the sorting labels and determines the display screen and display column corresponding to the central position of the concentrated crowd, and controls the moving distance of a plurality of display screens arranged at the center of the concentrated crowd from the position to the entrance of the gallery and the display information on the display screens and the display screens, and controls the moving distance of a plurality of display columns arranged at the entrance and exit of the gallery from the position to the entrance and exit of the gallery.

[0017] The present invention is further configured to include: a plurality of lamps arranged on the top of the exhibition hall, wherein the lamps are connected to a controller by telecommunication, and the controller controls the brightness of the lamps near the crowd to be reduced.

[0018] By adopting the above technical solution, the controller controls the brightness of the position lights near the crowd, making it convenient for the crowd to watch the display screen and the content on the display screen, thereby increasing the viewing effect.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The controller is used to control the movement of the display screen and the display column, so that the viewer can also see the displayed information when looking back, and can combine the content watched before with the content currently watched, thereby increasing the viewing experience and the publicity effect; at the same time, the position of the crowd is monitored and the display screen and the display column at the corresponding position are adjusted in real time to move, that is, to adjust the best viewing position and adapt it to the movement speed of the crowd.

[0026] The present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Example:

[0028] This kind of exhibition gallery display control system, such as Figures 1 to 3 As shown, it includes a plurality of display screens 15, display columns 12, a driving device 13 for driving the display screens 15 to move, a lifting device for driving the display columns 12 to rise and fall, a feedback device for detecting the position of the crowd, and a controller, and the controller is connected to the driving device 13, the lifting device, and the feedback device by telecommunication. The plurality of display screens 15 and display columns 12 are evenly distributed on the walls on both sides of the gallery along the gallery direction, and the driving device 13 drives the display screen 15 to gradually move from a low position close to and parallel to the wall to a high position perpendicular to and away from the wall. The controller receives the signal of the feedback device and controls the movement of the display screen 15 and the display column 12 respectively through the driving device 13 and the lifting device. The feedback device controls the display screen 15 and the display column 12 to display different pictures. The feedback device includes a first calculator and a plurality of pressure sensors 11, and the pressure sensors 11 are arranged on the gallery floor and a corresponding number is set for each pressure sensor 11. The force-bearing ends of the plurality of pressure sensors 11 are spliced ​​together to form a ground The calculator receives the signal from the pressure sensor 11, calculates the center position of the crowd and outputs the signal. The controller receives the signal from the calculator and drives the display screen 15 and the display column 12 at the corresponding position to move through the driving device 13 and the lifting device at the corresponding position. The feedback device receives the signal from the calculator and controls the display screen 15 and the display column 12 at the corresponding position to display different stored information. The display column 12 is composed of a plurality of display screens, and the plurality of display screens are perpendicular to the horizontal plane, and the display screens are connected to the calculator by telecommunications. The display screens on the plurality of displays and the display column 12 form sorting numbers respectively. The controller compares the relationship between the input signal from the calculator and the sorting number and determines the display screen 15 and the display column 12 corresponding to the center position of the crowd, and controls the moving distance of the plurality of display screens 15 arranged at the entrance of the gallery and the display information on the display screens 15 and the display screens, and controls the moving distance of the plurality of display columns 12 arranged at the entrance and exit of the gallery.

[0029] The exhibition hall further comprises a plurality of lamps 14 arranged on the top of the exhibition hall, wherein the lamps 14 are connected to a controller by telecommunication, and the controller controls the brightness of the lamps 14 to be reduced near the crowd.

[0030] A group of visitors enter the gallery to watch. The normal state of the display screen 15 and the display column 12 in the gallery is: the display screen 15 is parallel, close to the wall and located at a low position, the display column 12 is retracted into the ground, and the top of the display column 12 is in the same plane as the ground. When the crowd enters the gallery, the pressure sensor 11 that constitutes the ground and is located at the entrance of the gallery detects the pressure of the viewers on the ground and transmits the pressure signal to the calculator. The calculator receives the pressure signals of different pressure sensors 11 and extracts the sorting number of the pressure sensor 11, and the pressure sensors The sorting number of the pressure sensor 11 is the distance of the pressure sensor 11 relative to the gallery entrance, and then randomly extract the value in the middle of the sorting number of the pressure sensor 11 that transmits the signal, and then calculate the absolute value of the difference between the sorting number and the value of the pressure sensor, and then multiply the calculated value by the pressure value of the pressure sensor, and then sum the values ​​of the products calculated by the pressure sensors with sorting numbers less than the value and the values ​​of the products calculated by the pressure sensors with sorting numbers greater than the value, and subtract the sum of the former from the sum of the latter to obtain the data. When the data is between 1400, the The value is the middle position of the crowd, and the controller transmits the value signal to the controller, and the controller controls the display screen 15 with a sorting number less than the value to move. Specifically, the controller drives the display screen 15 to move through the driving device 13, and the controller only transmits signals to the five display screens 15 with sorting numbers closest to the value and moves them. When the viewer enters the gallery, the first display screen 15 moves once and shows a position state of 25% and maintains it. When the viewer moves to the position of the second display screen 15, the first display screen 15 moves a second time and shows a position state of 50% and maintains it, while the second display screen 15 moves a first time and shows a position state of 25% and maintains it. When the display screen 15 shows a position state of 100%, the display screen 15 receives a signal next time and moves from a position state of 100% to a position state of 0% and maintains it, so that the display screen 15 can always face the crowd as the crowd moves, so that the viewer can look vertically at the display screen 15 on the wall at his current position. When looking back, the display screen 15 far away from the viewer is also at an angle facing the viewer, thereby increasing the viewing effect.

[0031] At the same time, the controller controls the display column 12 to move up and down through the lifting device. When the display column 12 moves downward to the extreme position, the display column 12 retracts into the ground, and its top is on the same horizontal plane with the ground. The display screen opposite to the display screen 15 whose position status is 25%, 50%, 75%, and 100% controlled by the controller displays the second picture. The content of the second picture is adjusted according to the display content, and its color adopts black and white. The four display screens in the direction of the gallery exit relative to this position display the first picture. The content of the first picture is adjusted according to the display content, and its color adopts color. The other display screens retracted into the ground are turned off, so that the viewer can understand that the information is the content seen before and what happened before the viewer's current time when watching the black and white system, while the color system enables the viewer to understand the content he is currently watching, which greatly increases the viewer's sense of substitution for the development process of the event. The screen being retracted into the ground and closed can reduce power consumption. At the same time, the process of retracting into the ground and extending out can also make the viewer see less information when looking forward. After moving to the corresponding position, the displayed information is increased, which not only reflects the unknown future at the current time, but also reflects people's actions and attitudes when things happen, further enhancing the viewer's substitution effect and increasing the viewing experience; at the same time, the display screen 15 with a position status of 25%, 50%, 75%, and 100% displays general content, which is a summary and induction of the information that needs to be displayed at the position, so that viewers at a distance can "review" the content they have watched, and also refines important information and combines it with the viewer's position information, further increasing the display effect, and the display screen 15 with a position status of 0% displays the specific content of the current position, helping the viewer to understand all events occurring at the current time node in more detail;

[0032] At the same time, the controller controls the brightness of the lights 14 at the positions of the display screens 15 at the positions of 25%, 50%, 75%, and 100% and the display columns 12 extending out of the ground to reduce the interference of the lights 14 at other positions on the display screen and the content on the display screen 15, thereby increasing the viewing experience.

[0033] The driving device 13: uses a first motor to drive the rotating shaft to rotate, the rotating shaft drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the connecting shaft to rotate, the connecting shaft drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the display board to rotate with the connecting shaft axis as the rotation center, and then drives the display board to gradually rotate from a position parallel to the wall to a position perpendicular to the wall. When the rotating shaft rotates, the structure of the threaded sleeve meshing with the external thread on the rotating shaft, and the rotating shaft is restricted by the sliding groove, so that the distance between the first motor and the threaded sleeve is shortened when the rotating shaft rotates, that is, the rotating shaft gradually extends outward, causing the motor support plate to also extend into the exhibition gallery. At the same time, when the distance between the first motor and the threaded sleeve is reduced, the first motor is supported by the motor support plate, and the motor support plate The support plate is supported by a structure in which the support rod is slidably connected to the track groove, thereby driving the first motor to move along the track groove toward the opening position of the movable groove and move upward, thereby driving the display board to rise. At the same time, when the rotating shaft drives the rotating sleeve to extend outward, the rotating sleeve and the control block slide relative to each other. Because the control block is restricted by the limiting groove and the distance relative to the opening of the movable groove remains unchanged, and the control block does not rotate, the structure in which the connecting slider and the spiral groove on the control block are slidably connected makes the rotating sleeve rotate when it moves outward, thereby driving the connecting block, the connecting shaft, the worm gear, the driving gear, and the display board to rotate around the axis of the rotating sleeve, and the movement of the display board from top to bottom toward the middle of the gallery is coordinated with the movement of the display board from a position parallel to the wall to a position perpendicular to the wall.

[0034] Lifting device: The threaded shaft is driven by the second motor to drive the threaded sheet to move up and down. Four display screens are fixedly connected around the threaded sheet, and blocks are fixedly connected to the tops of the four display screens.

[0035] The calculator is a DSP chip, and the calculator is connected to the display screen and the display screen 15 by telecommunication. The display screen 15 and the display screen are provided with a memory, and a plurality of videos and pictures are stored in the memory. Different contents are displayed according to the signal received by the memory from the calculator.

[0036] The controller includes a motor controller connected to the first motor and the second motor, and a light controller connected to the light 14. The motor controller is a dual-drive two-in-one servo driver KYDAS48500-1E, and the light controller is JD2204.

[0037] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
