By the detailed description below with reference to accompanying drawing, it is obvious that other side of the present utility model and feature become.But it should be known that the only object design for explaining of this accompanying drawing, rather than as the restriction of scope of the present utility model, this is because it should be with reference to additional claim.Should also be appreciated that, unless otherwise noted, the unnecessary accompanying drawing of drawing to scale, they only try hard to illustrate conceptually structure described herein.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Fig. 1 is the configuration diagram of the LED display system of an embodiment of the present utility model.
Fig. 2 is the configuration diagram of the LED display system of another embodiment of the present utility model.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Fig. 1 is the configuration diagram of a kind of LED display system of an embodiment of the present utility model.As shown in Figure 1, LED display system 10 comprises the asynchronous control card 12 of LED display, a plurality of receiving card 14 and a plurality of LED casing 16; A plurality of LED casings 16 are stitched together and can obtain LED display.
Wherein, the asynchronous control card 12 of LED display comprises processing and control module 121, communication interface 123, maintenance interface 125 and shows data and state acquisition interface.Particularly, processing and control module 121 for example comprise embedded microprocessor and programming device, embedded microprocessor is mainly responsible for displaying contents being resolved to form the control signals such as displays content data and clock, synchronizing signal for programming device, and programming device is responsible for data-switching and gray-scale Control shows data and control signal to provide to LED lamp box 16; At this, embedded microprocessor is such as being arm processor or MCU (Microprogrammed Control Unit) etc., programming device is for example FPGA (Field Programmable Gate Array, field programmable gate array) device or CPLD (Complex Programmable Logic Device, CPLD) etc.In addition, being understandable that, is the running of matching embedded type microprocessor and programming device, and the asynchronous control card 12 of LED display also can arrange necessary auxiliary circuit, such as dynamic RAM and nonvolatile memory etc.
Show that data and state acquisition interface 127 are suitable for being electrically connected to LED casing 16 by receiving card 14, so that the status information that shows data and control signal and collect each LED casing 16 to be provided to each LED casing 16, such as opening circuit that single-point detects, short circuit, also has the information such as temperature, humidity, smog of LED casing.At this, show that data and state acquisition interface 127 are for example network interfaces.Preferably, showing that data and state acquisition interface 127 are structure as a whole, is also single structure, thereby showing that status information that data transmit and gather is transmitted on same interface completes; Certainly, the utility model, not as limit, can be also to show that data transmit and state acquisition is completed by network interface and winding displacement interface respectively.
Hold above-mentionedly, a plurality of receiving card 14 is electrically connected to demonstration data and the state acquisition interface 127 of the asynchronous control card 12 of LED display with cascade system.Each receiving card 14 band carries a LED casing 16, and each LED casing 16 is provided with a plurality of LED lamp plates.It should be noted that, the quantity of the receiving card 14 in the present embodiment is not limited to three, the concrete size of the LED display of building depending on actual needs, its can for one, two or more; Similarly, the quantity of LED casing 16 is also not limited to three, and general way is receiving cards 14 of a LED casing 16 configurations; In addition, the quantity of the LED lamp plate in LED casing 16 is also not limited to three.
