Embodiment
Now in conjunction with specific embodiments, technical scheme of the present invention is described, the present invention can also have other embodiments.All those skilled in the art under the prerequisite that does not break away from the principle of the invention, substitute or equivalent transformation by changing and retouching formed being equal to, all drop on the protection domain of requirement of the present invention.
Be the forward sight structural drawing of magnetic levitation device of the present invention with reference to figure 1, Fig. 2 is the forward sight structural drawing of LED display, and Fig. 3 is the overall appearance figure of magnetic levitation LED rotary display screen, and Fig. 4 is the workflow diagram of magnetic levitation device, and Fig. 5 is the workflow diagram of LED display.
Peripheral frame is concrete to be formed as shown in Figure 1, 2, mainly comprises magnetic levitation device support, first, second CPU module, lower circuit board 9, the first can 1, the second can 2, motor 6, LED matrix display 4, suspension switch board 8, infrared emission receiving sensor 7, infrared distance sensor 10.The suspension switch board is used for fixed electrical machinery and places the suspension device, is mainly to suspend with making to shield for the center of gravity of stablizing LED display; The second central processing unit is arranged on above motor, is to be sent to the LED display module for the character code that 51 single-chip microcomputers are received with rotation mode; Motor is fixed on the suspension switch board, and purpose is can driving display screen in motor rotation, makes the angular field of view of display screen can expand 360 degree to; The effect of magnetic levitation device support 2 is for fixing can; The first can installation infrared distance measuring sensor 10, the height of measurement suspension, the height of support is exactly the lifting height of suspension maximum; Place lower circuit board, magnetic field generator and power module part in the second can, the size of current of controlling in electromagnet is big or small with the magnetic force of controlling electromagnet, what send due to the infrared distance sensor on support is simulating signal, input end at the infrared simulation signal has added AD converter, and when making the height of LED rotary screen that any small variation be arranged, the magnetic force of electromagnet all needs to adjust.
The master chip of central processing module adopts STC89S52, a high-performance 8 bit processors based on 8051 kernels, the first central processing module 11 is used for measuring the suspension height and controls output current, the second central processing module 5 is used for the font code of reception and the control display output of font code wireless transmission, and lower circuit board is that the wireless power receiver module is used for receiving wireless power.
Power module, LED display needs+5V power supply.At first line voltage is carried out step-down through input transformer, use 7805 to obtain stable 5V voltage.Then voltage is divided into two-way, one tunnel direct supply circuit plate 1 work, other one road supply circuit plate 2 work.In the situation that the line voltage normal power supply charges a battery, when line voltage stops, producing and interrupt being powered by accumulator simultaneously.
Reseting module, the user's when operation of the electrification reset of the main completion system of reseting module and system button reset function, what the present invention adopted is better simply RC circuit, system powers on by resistance to capacitor charging, when the electric capacity position reaches the threshold voltage of high level, the RESET end is output as high level, and system is in reset mode.When the voltage at electric capacity two ends reached the voltage of high level, the RESET end was output as low level, system's normal operation.When the user pushed button, electric capacity two ends electric charge was released, RESET end output high level, and system enters reset mode, and reset key discharges electric capacity and is in charging process, and system enters normal condition.
Principle of work of the present invention is as follows:
This invention has the height of adjusting, font rotation and the adjustable LED display of rotating speed, and can realize utilizing by host computer the function of radio communication real-time update font demonstration, the transmission font code that the single-chip microcomputer of the second central processing module is interrupted utilizes people's persistence of vision to come Display of Chinese characters or letter.
When the user need to change the content of wanting reality, content that only need to input will show on the host computer interface of control end, then generate corresponding binary code, then send to these font codes in the internal data register of the NRF24L01 on circuit board 1 by the control end single-chip microcomputer, after two client informations are synchronous, transmitting terminal is delivered to data the data register of the NRF24L01 of receiving end, then set up communication with the second central processing module single-chip microcomputer, single-chip microcomputer is sent to LED display after with information processing.
When the user need to change the rotating speed of display screen, the pulse signal that only needs 51 single-chip microcomputers generations of change the second central processing module, what we normally used is that dutycycle is 0.6 signal, when needs change rotating speed, the dutycycle that arranges to change pulse signal of the initial value by revising timer in 51 single-chip microcomputers, then by the distribution of signal, power amplification can be sent into direct current generator to reach the effect of controlling motor speed.
When the user need to change the height of display screen, can change by the size of current in the change electromagnet magnetic force size of electromagnet, namely change the adjusting limit switch that the solenoid input drives the input of L293D, magnetic field force size and gravity equal and opposite in direction during due to the display screen balance, cross and to be in equilibrium state, when changing the magnetic force size of electromagnet, suspension can rise thereupon or descend, and will enter the another one equilibrium state again.Because the output signal that goes up the infrared distance sensor of installing in can 1 is simulating signal, producing a small analog quantity when the Level Change of our suspension changes, and this moment, single-chip microcomputer can not be identified, need to change by AD, processing through the single-chip microcomputer on central processing module 1 just can be controlled output voltage, by driving to reach the effect of regulation output electric current, play the effect of regulating the suspension height.
The course of work of the present invention is as follows:
Magnetic levitation device: measure length by the infrared distance sensor in rack-mount end the first can in the time of initialized, if length equals the length of support, illustrate that do not have object to put this moment, do not produce magnetic field in electromagnet, when having object to put, the length of measurement is less than support height, 51 single-chip microcomputers in the first central processing module can produce output signal at this moment, and convert the pulse signal of electric current to, produce magnetic field in electromagnet, suspend to cause object.When the hoverheight of the size that will change object or object, can be by regulating the limit switch on the second can, the magnetic force that increases magnetic field makes the object hoverheight become large, in like manner if reduce the height of suspension as long as reverse direction is regulated limit switch (detailed process is asked for an interview Fig. 3).
LED display: at first power on to whole system, be divided into two parts, the first direct supply directly begins rotation to motor power supply motor this moment, second, LED display is to adopt the wireless power technology, at first be that direct current is converted to alternating current, then alternating current is converted to direct current to supply with LED demonstration use.After aspect, two of fronts is all ready, be arranged on magnetic suspension control infrared emission receiving sensor cashier's office in a shop just begin to detect the second CPU module whether forward to its top, if not, on the second central processing module, the data of Last status are waited for always and kept to single-chip microcomputer, the second CPU module forwards its top to, if, send into next font code, whether reexamine powered-down, if it is finish, if not, continue to carry out, circulation shows the content that will show.
