Abstract
The utility model discloses an LED (Light-Emitting Diode) display screen controller and belongs to the technical field of LED display. The LED display screen controller comprises a control board and a changeable transmission medium card, wherein the control board is provided with a control circuit and a PCL (Peripheral Component Interconnect) interface, which are electrically connected; and the transmission medium card is connected onto the PCL interface in a pluggable manner. According to the LED display screen controller disclosed by the utility model, the control board can be shared and only the transmission medium card needs to be changed under different transmission manners, so that the cost is saved, and the controller has the strong generality and is convenient to produce; and one type of products can be produced in a large batch, the PCL interface is utilized to be convenient for plugging, and the reliability is high.
Description
Technical field
The utility model relates to LED display technique field, relates in particular to a kind of LED display controller.
Background technology
Industry like product control system slave controller is varied to the signal transmission form of screen at present, and for example Network Transfer Media can be selected 100M Ethernet card, 1000M Ethernet card etc., but in general; Transmission medium is directly to be arranged on the controller, and promptly transmission medium is the part of controller, and both are inseparable; If a company adopts multiple signal transmission medium must use the various control device, like 100M Ethernet or 1000M Ethernet, just must 100M and the controller of 1000M; Cause product many more; The controller kind is many more, and production control and management are more numerous and diverse, and the controller versatility is poor.
The utility model content
The technical matters that the utility model mainly solves provides a kind of LED display controller with good versatility.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of LED display controller is provided; Comprise control panel and removable transmission medium card; Said control panel is provided with the control circuit and the PCL interface of electrical connection, and said transmission medium card plug is connected on the said PCL interface.
Wherein, said transmission medium card comprises 100M network card, 1000M network card, sonet card, DVI card, HDMI card, VGA card, SDI card.
Wherein, said PCL interface is horizontal connect-disconnect structure, and the transmission medium card that is plugged in the said PCL interface is parallel with said control panel.
Wherein, said PCL interface is set at least two, and said control circuit comprises network control circuit and display control circuit, and one of them PCL interface is electrically connected with said network control circuit, and another PCL interface is electrically connected with said display control circuit.
Wherein, the PCL interface on the said control panel is the PCL slot, and said transmission medium card is provided with and the suitable PCL golden finger of said PCL slot.
The beneficial effect of the utility model is: be different from that the various signals transmission medium need use the Different control device in the LED display of prior art, the versatility of controller is poor, and the utility model provides a kind of LED display controller; It is provided with the PCL interface on control panel, the transmission medium cartoon is crossed the plug of this PCL interface and control panel and is connected, and when using different transmission modes corresponding transmission medium card is plugged on the control panel to get final product; Control panel can be changed the transmission medium card by shared need like this, thereby practices thrift cost, controller highly versatile; Convenient production; Can produce a kind of product in enormous quantities, adopt the plug of PCL interface convenient, reliability is high.
Description of drawings
Fig. 1 is the structural representation of the LED display controller of the utility model.
The accompanying drawing mark:
10, control panel; 11, PCL interface; 20, transmission medium card.
Embodiment
By the technology contents, the structural attitude that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
See also Fig. 1; The utility model provides a kind of LED display controller; Comprise control panel 10 and removable transmission medium card 20, control panel 10 is provided with control circuit (not shown label) and PCL interface 11, and control circuit is the general designation of each module of completion respective control function (demonstration and the signal between the LED display of control LED display transmit, receive external control order etc.); In Fig. 1, only illustrated the individual metablocks device; Each element and annexation want complicated many certainly on the control panel of reality, because concrete control circuit is not the emphasis of the utility model, therefore do not do too much introduction here.
More excellent ground, PCL interface 11 is set at least two, and one of them PCL interface 11 is used for being connected with the network interface card of transmission medium card 20, and correspondingly, the network control circuit that is used for Control Network in this PCL interface 11 and the control circuit is electrically connected; Another PCL interface 11 is used for being connected with the video card of transmission medium card 20, correspondingly, is used for the display control circuit that control of video shows in this PCL interface 11 and the control circuit and is electrically connected.If control panel 10 is provided with the PCL interface 11 more than two, then other PCL interface 11 can design its function as required.Thus, the abundant function of extending controller.
In the present embodiment, PCL interface 11 is designed to horizontal pulling/inserting structure, and promptly its row's pin is parallel to control panel 10 plate faces, and the transmission medium card 20 that is plugged in thus in this PCL interface 11 is parallel with control panel 10.Can reduce the thickness of controller like this, convenient toward the miniaturization development.
In the specific implementation, the PCL interface 11 on the control panel 10 is the PCL slot, and grafting is convenient, cost is low, durable; Be provided with and the suitable PCL golden finger of this PCL slot on the transmission medium card 20, the reliability height is not fragile.
Be different from that the various signals transmission medium need use the Different control device in the LED display of prior art, the versatility of controller is poor, and the utility model provides a kind of LED display controller; It is provided with the PCL interface on control panel, the transmission medium cartoon is crossed the plug of this PCL interface and control panel and is connected, and when using different transmission modes corresponding transmission medium card is plugged on the control panel to get final product; Control panel can be changed the transmission medium card by shared need like this, thereby practices thrift cost, controller highly versatile; Convenient production; Can produce a kind of product in enormous quantities, adopt the plug of PCL interface convenient, reliability is high.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
