All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide a linear LED lamp image-text display skipping rope based on visual persistence and a using method thereof, so as to solve the problem of poor functionality of the existing skipping rope.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Example 1:

the embodiment provides a linear LED lamp image-text display skipping rope based on persistence of vision, which, as shown in fig. 1 and 2, comprises a skipping rope body 1, wherein a handle of the skipping rope body 1 is internally integrated with an MCU module 11, and a handle module 12, an LED lamp strip module 13, a power management module 14, a bluetooth data transmission module 15 and a voice broadcast module 16 which are electrically connected with the MCU module; an LED lamp strip is arranged in the rope of the skipping rope body 1 and is electrically connected with an LED lamp strip module 13; the Bluetooth data transmission module 15 is also in wireless connection with the smart phone 2, and the smart phone 2 is in wireless connection with the cloud server 3.

Specifically, LED lamp area comprises 23 LED lamp pearls.

Further, the smart phone 2 is provided with an APP, and the APP comprises a bluetooth connection and management module, a bluetooth data transmission module 21, a code scanning module, a test module, a UI display module, a network data transmission module 22 and a user login module.

Further, the cloud server 3 includes a user account information module, a data analysis module 31, a data storage module 32, a data transmission module 33, and a maintenance module 34.

The embodiment also provides a use method of the linear LED lamp graph-text display skipping rope based on persistence of vision, as shown in fig. 3 and 4, including the following steps:

(1) a user logs in a cloud server through an App of a smart phone to synchronize data;

the user installs the appointed App software, and registers and logs in the App software, and when the App software is used for the first time, the App software reports personal body parameters of the user, such as gender and age. And (3) logging in the App synchronous cloud personal motion data every time, and displaying historical motion conditions, namely rope skipping times, consumed calories and motion time. The user can make a standard exercise plan based on personal physical parameters.

(2) The user establishes Bluetooth data connection with the skipping rope body through the App of the smart phone and sets a motion mode; the user passes through the smart mobile phone App discernment rope skipping and establishes bluetooth data connection, and after the connection succeeds, sets up rope skipping motion mode through the App, like free motion mode, count-down motion mode. The flexible movement mode setting can fully meet the movement requirements of the user and simultaneously can prevent the user from being overworked.

(3) A user sets an LED lamp strip display mode and pictures and texts of the skipping rope body through an APP of the smart phone; after the smart phone App and the skipping rope establish Bluetooth data connection and set the motion mode. The user sets up rope skipping LED lamp area display mode and picture and text through smart mobile phone APP, such as number mode, pattern mode etc..

The smart phone App carries out coding pretreatment on the content to be displayed to obtain a file after coding, and the file is transmitted to the skipping rope through a Bluetooth protocol and stored.

The smart phone App provides custom texts and graphs and scrawling making, and then generates data of each frame according to the graphs and sends the data to the skipping rope. The patterns displayed by the skipping rope linear LED lamp in the skipping rope rotation mode are all formed by scanning in a picture mode, continuous pictures are generated due to the persistence of vision of human eyes, so what contents need to be displayed are changed into corresponding pictures, 1 string of lamp strips are arranged on the skipping rope and consist of 23 LED lamp beads, as shown in figure 4, each number occupies 5 lamp beads, 1 lamp bead is arranged between each number, and 4 numbers can be displayed in total, namely 0000 + 9999. In order to achieve the smoothness of rope skipping LED lamp display, the smart phone App transmits data by taking a frame as a minimum unit, one frame is a static picture, each frame corresponds to a group of data, and the data is binary data corresponding to a lamp array.

(4) The skipping rope body works according to the setting of a user and dynamically displays the LED pictures and texts; as shown in fig. 3, the skipping rope MCU receives the encoded data through the bluetooth protocol and stores the encoded data in the memory, and the MCU controls the color and brightness of the LEDs on the rotating arm according to the real-time attitude angle to realize that the LED display device displays the content to be displayed whose brightness can be adjusted at will.

The LED lamp strip rotates under the drive that the user jumped on the rope skipping, every rotation certain angle, changes LED display content, because human vision has the persistence phenomenon, when the object is in the rapid motion, after the image that people's eye saw disappears, still can continue to keep its image about 0.1 to 0.4 second time, when motor speed is fast enough, when the time of rotatory round is shorter than the time of people's eye's reaction, just can use a lamp strip 1 to show a complete image through the rotation.

The rope skipping movement adopts an arc-shaped LED linear array as a display dot matrix in the warp direction on the spherical surface, the LED is controlled to be on or off in a timing mode through rotation in the central shaft direction, characters or patterns are observed by using the visual persistence effect of human eyes, the dynamic picture is divided in the weft direction, and dynamic pixels based on division of the warp and the weft in the spherical surface are formed. Setting the rotation starting point position as the first row, the rotation angular velocity as ω, and defining a minimum step angle Δ θ, which represents the rotation angle of the LED lattice, the spherical space is divided into m parts, where m is 2 pi/Δ θ. Since the rotary linear array is provided with n LEDs, the size of the pixel displayed by the spherical surface is mxn. I.e. 23 m.

When the rotation speed is omega₀When it is alongThe moving time T of two adjacent pixels of the weft is T/m (called the minimum step refresh time), where T is defined as the time required for one rotation (called the rotation period). When the speed of rotation changes suddenly, i.e. ω_i＝kω₀(k > 0), keeping the refresh time constant, and then the minimum step angle at this time is:

Δθ_i＝ω_it＝kω₀t

therefore, the change of the angular speed causes the equal proportion change of the step angle, and for the spherical surface, according to the principle of step angle equal division, the virtual pixel point in the weft direction changes, m_i＝2π/kω₀t. If k is larger than 1, the angular velocity is increased, and the number of pixels in the spherical space along the weft direction is reduced.

If the number reaches a certain number, such as 100, the skipping rope can also broadcast data in a voice mode and display celebratory pictures, and the sport fun is increased.

(5) The skipping rope body uploads user motion data to the smart phone through the Bluetooth communication module; the rope skipping data are transmitted to the smart phone App through a Bluetooth communication protocol to be displayed, and the rope skipping data comprise rope skipping times, exercise time, calories consumed and the like.

(6) The user uploads the motion data and the LED image-text to the cloud server through the App of the smart phone; the smartphone App displays the rope skipping times, exercise time, calories consumed, and the like on the UI, and also uploads data to the cloud server. The user uploads the self-edited pattern to the cloud server through the smart phone App so as to facilitate next use or community sharing.

(7) The cloud server stores user data, performs motion analysis, and simultaneously stores interesting LED pictures and texts for community sharing. The cloud server is responsible for storing data of all users, analyzing the motion data and prompting the users. The interesting LED patterns uploaded and shared by the users are used for being exposed to the community platform by the cloud server, so that the labor achievements of the users are shared, and the users can experience the effects.

Further, the method also comprises the following steps:

(8) when the battery power of rope skipping body was low excessively, the APP suggestion user of smart mobile phone charges. The lithium cell that the rope skipping provided, but audio playback and LED lamp show all can be power consumptive, and when detecting that battery power is low excessively, App can report an emergency and ask for help or increased vigilance the user, need charge for equipment, can recharge.
