Description
Technical field
The utility model relates to a kind of LED display, particularly relates to the device that a kind of hand-held LED controlled based on blue teeth wireless shows.
Background technology
Along with the continuous progress of China's science and technology, LED technology is also at development, due to LED display it to have brightness high, operating voltage is low, power consumption is little, maximize, life-span is long, the features such as shock-resistant and stable performance are subject to widespread use and are developed rapidly, and existing LED display screen control device passes through LAN (Local Area Network), infrared, the mode such as radio and laser transmits data, but it is high that these modes also exist cost, the shortcomings such as complicated operation and instability, particularly be applied in some small advertisement LED screen, because existing LED display screen control device cost is higher, complex structure, bulky, control and the higher defect of maintenance cost can not be moved, so people finding always more convenient, the device of stable and economic LED display and control.
Summary of the invention
The purpose of this utility model is the device providing a kind of hand-held LED controlled based on blue teeth wireless to show, solve existing LED display screen control device and transmit data by LAN (Local Area Network), infrared, the mode such as radio and laser, but these modes also exist, and cost is high, the shortcoming such as complicated operation and instability, particularly be applied in some small advertisement LED screen, because existing LED display screen control device cost is higher, complex structure, bulky, the problem that can not move control and the higher defect of maintenance cost.
The utility model realizes like this, it comprises computing machine, bluetooth host, bluetooth is from machine, single-chip microcomputer, LED display, it is characterized in that: described computing machine, bluetooth host, bluetooth is from machine, single-chip microcomputer is connected successively with LED display, described computing machine is connected by USB data line with bluetooth host, described bluetooth host and bluetooth carry out wireless transmission from machine by HC-05 bluetooth serial ports, described bluetooth is connected the RXD interface pin of single-chip microcomputer by wire from machine and single-chip microcomputer, described single-chip microcomputer is connected by I/O port with LED display, described single-chip microcomputer is STC12C5A60S2.
The preferred 74HC595 of described single-chip microcomputer.
The preferred 74HC154 of described single-chip microcomputer.
The preferred ULN2803 chip of described single-chip microcomputer.
Described single-chip microcomputer high speed crystal oscillator is as playing vibration source.
Technique effect of the present utility model is: write that the utility model can realize the Dynamic Announce of LED display, Circulating fibrocytes, brightness regulation, rate of circulation regulates, character is wireless and showing in real time, and the utility model can install battery, thus realize ambulatory handheld travelling control LED display, substantially increase convenience and the stability of LED display control.
Accompanying drawing explanation
Fig. 1 is control flow chart of the present utility model.
Fig. 2 is the Chinese character delivery process flow diagram of labview software of the present utility model.
Embodiment
Composition graphs 1, 2 illustrate the utility model, described computing machine, bluetooth host, bluetooth is from machine, single-chip microcomputer is connected successively with LED display, described computing machine is connected by USB data line with bluetooth host, described bluetooth host and bluetooth carry out wireless transmission from machine by HC-05 bluetooth serial ports, described bluetooth is connected the RXD interface pin of single-chip microcomputer by wire from machine and single-chip microcomputer, described single-chip microcomputer is connected by I/O port with LED display, described single-chip microcomputer is STC12C5A60S2, described single-chip microcomputer 74HC595 transmits and latch data, described single-chip microcomputer 74HC154 realizes the row gating to dot matrix, described single-chip microcomputer ULN2803 chip drives LED display dot matrix, described single-chip microcomputer high speed crystal oscillator is as playing vibration source.
As shown in Figure 2, this is the Chinese character delivery process flow diagram of the labview software of computing machine, the utility model adopt in labview open/create/alternate file control carrys out the dot character library file that middle reading has been downloaded, and utilize the size that document location control and side-play amount are set to obtain inputting the character pattern data of Chinese character, mainly contain two crucial controls, document location control is set and reads text control, arranging document location is that side-play amount offset by having calculated finds the input position of Chinese character in Chinese character dot matrix font file, because the dot matrix Chinese character size of 16 × 16 is 32 bit, therefore need to read 32 data continuously from first address, text is read so adopt, and arrange its counting port be 32, its internal code is obtained by adopting array related control, and utilize formulae discovery to draw offset, so just obtain the character pattern data of a Chinese character, in order to obtain a series of character pattern data, a powerful function f or cyclical function is provided in labview, by for function, we can extract the character pattern data of each Chinese character, and calculate the number of input Chinese character, in the labview software write, Chinese character is inputted as long as this achieve, click to send and just can show in real time on a display screen.
During use, be energized to this device by power supply, afterwards in computing machine labview software obtain the character pattern data of Chinese character needing display, character data is sent to single-chip microcomputer from machine afterwards by bluetooth host and bluetooth, single-chip microcomputer starts after obtaining the character pattern data from computing machine to control display screen display, character data is shown in LED display.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
