Abstract
The utility model relates to a USB (Universal Serial Bus) flash disk for an LED (light-emitting diode) control card, which comprises a USB flash disk main body having a USB interface in communication connection with a computer on one end, wherein the other end of the USB flash disk main body is provided with a serial port in communication connection with an LED control system, and the serial port is in communication connection with a CPU inside the USB flash disk main body so as to utilize the LED control system to read the data in the USB flash disk main body through the serial port. The equipment usage is similar to the USB flash disk usage, the communication distance reaches above 20 meters, the USB flash disk is compatible with the current control system, the production cost of LED control card can be efficiently lowered, the use value thereof is high and the market prospect is wide.
Description
Technical field
The utility model relates to a kind of LED control card USB flash disk.
Background technology
The programme content of LED display is sent in the control card of LED screen through RS232 or Ethernet mainly by Computerized Editing at present.In the application in some difficult wiring or mobile place (as vehicle-mounted), there is the problem of poor operability.Another kind of programme transmission mode adopts USB flash disk on the market, deposits programme content in USB flash disk earlier, reads program in the flash disk by control card then.Though it is easy to use that USB flash disk transmits program, can only be used in the screen periphery operation, can't satisfy the practical engineering application requirement, and need special control card, can not with existing LED control card compatibility, increased the cost of display screen.
Prior art adopts USB flash disk to solve this problem usually, mainly has following three problems:
Control system needs internal USB HOST(USB main equipment), control system need increase this part hardware capability like this, has improved system cost;
Must not surpass 5 meters according to USB standard, its transmission range, so can't realize control with USB flash disk in higher place, a lot of screen installation sites;
In addition,,, need all be replaced by control card the control card of band USB interface, cause waste if will increase the USB flash disk control function for existing screen.
Summary of the invention
The purpose of this utility model is to provide a kind of LED control card USB flash disk, and this equipment uses similar to USB flash disk, and communication distance reaches more than 20 meters, compatible mutually with existing control system, can reduce the production cost of LED control card effectively, its use value height, market outlook are wide.
Of the present utility model being characterised in that: a kind of LED control card USB flash disk, the USB flash disk main body that comprises the USB interface that is connected with the computing machine communication that an end is provided with, described USB flash disk main body comprises master chip, storage chip and shell, it is characterized in that: the other end of described USB flash disk main body is provided with the serial ports that is connected with the communication of LED control system, described serial ports is connected with the CPU communication of USB flash disk body interior, reads the data of USB flash disk body interior by serial ports in order to the LED control system.
The CPU of above-mentioned USB flash disk body interior has the USB flash disk module for reading and writing.
The master chip of above-mentioned USB flash disk main body is C8051F321.
The storage chip of above-mentioned USB flash disk main body is SST25VF080.
The shell of above-mentioned USB flash disk is general 232 quick shells.
The beneficial effects of the utility model: the one, owing to used this product, LED to shield when selecting control card for use, as long as, need mobile storage freely to increase in the future with common LED screen control card.The user need not to select the high dedicated control system of price for use because consider mobile storage as long as select the most economic control card according to screen size; The 2nd, the control card of original tape USB flash disk function is to link to each other with the U card by usb bus, and it is 5 meters that communication prolongs distance the longest.And be by the work of serial ports (RS232) pattern when this product and control card communication, communication distance can reach 50 meters.The 3rd, if will increase the USB flash disk control function, do not need control card all is replaced by the control card of band USB interface, saved production cost, improved economic benefit.
