Abstract
The utility model relates to an LED display screen wireless control system which comprises a sending terminal, an LED control card and an LED display screen, wherein the sending terminal is connected with the LED control card through a GSM network, and the LED control card is in wired connection with the LED display screen. Compared with the prior art, the LED display screen wireless control system provided by the utility model has the advantages of stable communication, high security, a simple structure, convenient usage and the like.
Description
Technical field
The utility model relates to a kind of LED display control system, especially relates to a kind of wireless control system of the GSM of support network ultralong short message.
Background technology
The LED control card developed about 10 years, but most card remains the connection of wired mode, is flooded with the USB flash disk card on the market, the network interface card, and serial port board etc., unruled card have only occupied a small amount of share.And along with the gradually diversification of application scenario, the LED control card also gradually be transformed into popular consumer goods from industrial goods, its application is greatly expanded, everybody can see that everywhere LED control flow card gets figure.But, LED wireless controlled fabrication aspect just at present, development still be not very ripe, substantially all adopt the GPRS mode, the GPRS mode has possessed real time reaction, larger advantages such as carrying data, has obtained comparatively general application.But also expose gradually some problems, for example: the user need to give training specially, uses very inconveniently, safeguards flow that link produces, can't communicate by letter when network signal is bad, and security is bad, is attacked easily extra-pay burden etc.
The utility model content
The purpose of this utility model is exactly that a kind of communication robust, safe LED display wireless control system are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of LED display wireless control system, comprise transmitting terminal, LED control card and LED display, described transmitting terminal is by GSM network connection LED control card, and the mode by note sends control information described LED control card and LED display wired connection to the LED control card.
Described LED control card is connected by 08 interface or 12 interfaces with LED display.
GSM communication module, power module, clock module, storer and scan drive circuit that described LED control card comprises processor and is connected with processor, described GSM communication module passes through GSM network connection transmitting terminal, the LED display that described scan drive circuit connects.
Described GSM communication module comprises antenna and SIM card, when not using SIM card, can pass through the serial mode input control information.
Described processor is the ARM chip.
Compared with prior art, the utlity model has following advantage:
1, communication is reliable: note possesses the ability at server buffer, and is unblocked by the short message receiving-transmitting of GSM network when GPRS network sometimes can't be stablized in the situation of connection, even the receiving end shutdown is reissued after still can starting shooting.Adopt the information issue of short message mode substantially can accomplish the transmission that to lean on.
2, safe: by using short message mode, judge legitimacy according to the number that sends note, security is based on GSM network and SIM card, and is very safe.
3, not limited by the note character length: the maximum length of note is i.e. 70 Chinese characters of 140 bytes generally speaking, overlength will automatically be deleted and be exceeded part, this will cause the data volume restriction of the information content, the note of overlength can be split into many automatically, after being received respectively by the LED control card, be combined into complete note, maximum length is relaxed can reach 500 Chinese characters, substantially can satisfy the requirement of much information issue.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of LED display wireless control system comprises transmitting terminal 1, LED control card 2 and LED display 3.Wherein, transmitting terminal 1 is generally computer, mobile phone or network control platform etc., and other can send the electric terminal equipment of note, LED control card 2 has comprised processor 21 and the GSM communication module 22 that is connected with processor 21, power module 25, clock module 26, storer 23 and scan drive circuit 24, GSM communication module 22 is comprised of antenna and SIM card, be used for receiving the note that transmitting terminal 1 sends by the GSM network, because SIM card can be separated with the LED control card, when not using SIM card, can pass through the serial mode input control information.Processor 21 adopts the ARM chip, the note that receives is processed, obtain control information, the storer 23 general FLASH memory devices that adopt the outside, be used for preserving some information of processing procedure, power module 25 and clock module 26 are respectively applied to provide power supply and system clock, and scan drive circuit 24 is used for the control signal of LED display 3 is carried out power amplification, and by 08 interface or 12 interfaces of 16pin content to be shown is exported on the LED display.
When sending note, the content of its control information adopts the coded system of Unicode, when its content exceeds length restriction, it is split the control information after recombinant splits during reception when sending.In this way, solved the obstacle that a lot of LED wireless control systems can't show long short message content, and use and only show that a note or a long SMS mode have solved the complicated loaded down with trivial details problems of management such as many short message content storages, inquiry, deletion, judge that according to the number that sends note the legitimacy in note source solves safety issue simultaneously, whole system is simple in structure, safety, easy to use, substantially can satisfy the requirement of much information issue.
