The invention is divided into a server end and a client end, wherein the server end is mainly responsible for receiving media data (pictures and videos) to be displayed, processing and finally forwarding; the client side is primarily responsible for accepting data and driving the display.

As can be seen from the functional block diagram of the server device in fig. 1, the components of the server side are a network transmission module, a data storage module, a data conversion module and an operating system. In the invention, the server runs based on a Linux operating system. The network transmission module has the main function of carrying out C/S communication, the connection establishment mode is TCP connection, and the function of the network transmission module is to send the picture data received by the server to the client; the realization of the data storage module depends on a database, and the function of the data storage module is to temporarily store the received data in the corresponding category of the database as a record; the data conversion module is used for calculating data, and conversion of the picture from a plane rectangular coordinate system to a polar coordinate system is achieved.

As can be seen from the client-side functional block diagram of fig. 2, the client-side components are a power module, a data receiving module and a motion control module. The data receiving module is divided into a network data receiving part and a data storage part; the motion control module is divided into a data conversion part, a motor driving part and an LED lamp group driving module.

As can be seen from the client hardware configuration and working diagram of fig. 5, the client-side hardware mainly includes: the LED lamp bank comprises a power supply module, an MCU and a minimum system thereof, a speed reducing motor and a driving circuit thereof, an LED lamp bank and a driving module thereof and a WIFI communication module. The LED lamp bank and the driving module thereof are used for motion control, the WIFI communication module is used for network data receiving, and the MCU and the minimum system thereof are a main controller.

The server side has the following functions: (1) and deploying a webpage to acquire the picture/video data information uploaded by the user. (2) The picture/video information is processed (different processing modes are adopted for different data types), so that the picture/video information is easy to rotate, display and display. (3) And storing the converted data through a database to generate record information. (4) And establishing a stable TCP connection with the client. (5) And packaging the converted information according to a certain communication protocol and sending the packaged information to the client.

The function composition of the client side is as follows: (1) and establishing a stable TCP connection with the server. (2) And receiving picture information data information sent by a server, and analyzing according to a preset communication protocol. (3) And processing the data information into driving information of the LED lamp group and the motor, and storing the driving information in the memory in a multi-dimensional array form. (4) The driving motor and the LED lamp set perform rotary display.

The operation of the system requires the cooperation of each module, and the operation flow is divided into two relatively independent parts in the invention: the operation flow of the server side and the operation flow of the client side.

As can be seen from the system workflow of fig. 3, the coordination operation flow between the modules at the server side is as follows:

firstly, starting a server to initialize, and completing system configuration: and deploying the webpage to wait for the user to operate, establishing TCP connection with the client, and detecting the integrity of the database. And after the configuration is finished, waiting for the user to upload the picture information and the video information to be displayed. If valid information is collected, the type of information is classified: video or picture, and reference the corresponding processing program, and its core lies in that the data is undergone the conversion of coordinate axis and separated from channel. The coordinate transformation algorithm refers to the transformation from an inter-plane coordinate system to a polar coordinate systemThe information size of the original image is (X)_N,Y_NP), wherein X_NRefers to the width, Y, of the image_NRefers to the height of the picture and P refers to the number of channels of the picture (here typically 3). But this is expressed in planar rectangular coordinates, and when the image appears under a circular area, a polar coordinate system should be used. There is a transformation from the inter-plane coordinate system (X, Y) to the polar coordinate system (θ, ρ). After the data is processed, the data is stored through a database to generate record information. And finally, packing and sending the data to the client according to a certain communication protocol through the socket connection. Namely, a work flow is completed.

Meanwhile, as can be seen from fig. 3, the coordination operation flow between the modules at the client end is as follows:

firstly, the system is electrified and self-started to complete initialization configuration: hardware initialization and connection establishment with a server. After the configuration is finished, the network data receiving module waits for effective information from the server, and if the effective information is received, the data is classified: and (4) video or pictures, calling corresponding processing functions, and finally, converting the video or the pictures into frame-by-frame display. The MCU converts the received data into control information according to the received data, and stores the control information in a memory in a multi-dimensional array form. And finally, the MCU drives the motion control module to display the picture frame.

In summary, the multi-arm rotary display system supporting networked graphic display provided by the invention comprises the following steps:

the first step is as follows: and starting the server side equipment and the client side equipment to finish initialization.

The second step is that: the server side and the client side are connected through TCP to establish communication. Then, the client sends the local identification number and the relevant configuration information to the server, and the server stores the local identification number and the relevant configuration information in a corresponding form of the database after receiving the local identification number and the relevant configuration information.

The third step: after the server side starts the service, the user waits for uploading the picture or video information to the server through the webpage. For picture information, the server will accept directly; for video information, the server will parse the video information according to a preset frame rate.

The fourth step: after receiving the data transmitted by the user, the server calls a data conversion module, processes the data through algorithms such as coordinate transformation, channel separation and the like, and processes the original information into data information which can be received by the client. This part of the information will be stored in the database.

The coordinate transformation algorithm refers to the transformation from a plane coordinate system to a polar coordinate system, and the information size of an original image is (X)_N,Y_NP), wherein X_NRefers to the width, Y, of the image_NRefers to the height of the picture and P refers to the number of channels of the picture (here typically 3). But this is expressed in planar rectangular coordinates, and when the image appears under a circular area, a polar coordinate system should be used. There is a transformation from the inter-plane coordinate system (X, Y) to the polar coordinate system (θ, ρ). With particular reference to the transformation of the planar rectangular to polar coordinate system of fig. 4.

The fifth step: the server side packs the data and sends the data to the client machine according to a certain communication protocol.

And a sixth step: the client end receives the data and processes the data into driving signals of the LED lamp group and the motor so as to drive the equipment to operate and display image information.

And the data processing in the sixth step is mainly performed by a client-side single chip microcomputer part, and the data is stored in a memory in a two-dimensional array form and then is called by a display module.

Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
