Description
Technical field
The utility model relates to the radio operation apparatus field, relates in particular to a kind of radio operation equipment of LED display.
Background technology
The operations such as the Play Control of LED display all need to be finished by connecting computing machine traditionally.Traditional LED display is carried out Long-distance Control by operation computing machine in machine room.
Along with the application of LED display is promoted gradually, at the vehicles that flow, such as having used more and more LED display on the rail transit train.For the LED display of using at the vehicles, traditional mode that operates in machine room can't re-use.Because the operating personnel in machine room can't real-time monitor the play content on the LED display on the vehicles, do not understand and know no LED display normal operation.If operate at the scene, according to traditional approach, need a large amount of equipment of configuration, such as a large amount of peripherals such as keyboard, mouse, these vehicles at narrow space seem very inconvenient.
In fact, the most shirtsleeve operations of operation at the scene such as controlling cursor movement, affirmation, playing, stop, deleting etc., do not need very complicated operation.If LED display breaks down, then still need to get back to the machine room maintenance.Therefore, be suitable for carrying out at the scene simple operations, operating equipment easy to carry with regard to needs are a kind of.
The utility model content
The utility model is intended to propose a kind of radio operation equipment that can carry out the simple functions operation in short distance to LED display.
According to an embodiment of the present utility model, a kind of radio operation equipment of LED display is proposed, comprise receiving end device and transmitting end device.Receiving end device is installed on the LED display, and receiving end device is connected to the instruction input port of LED display, and receiving end device comprises wireless receiver and demoder.Transmitting end device comprises instruction inputting device, scrambler and wireless launcher, and instruction inputting device receives the input instruction, and scrambler is connected to instruction inputting device and to the input instruction encoding, the wireless launcher emission is by the input instruction of encoder encodes.Wireless receiver receives encoded input instruction, and the encoded input instruction of demoder decoding obtains inputting instruction, and demoder carries the input instruction to the instruction input port of LED display.
In one embodiment, instruction inputting device comprises tracking ball and nine key boards.Comprise the four direction operating key on nine key boards.
In one embodiment, the instruction input port of LED display is USB interface, and receiving end device has the USB plug receptacle.
In one embodiment, the operating distance of wireless launcher and wireless receiver is 10 meters.
The radio operation equipment of LED display of the present utility model can be realized the simple operations to LED display in short distance, such as the control cursor movement, carry out simple logical operation etc., meets the execute-in-place requirement of LED display.
Description of drawings
Fig. 1 has disclosed the structural representation according to the transmitting end device of an embodiment of the present utility model.
Fig. 2 has disclosed the scheme of installation according to the receiving end device of an embodiment of the present utility model.
Embodiment
The utility model is intended to propose a kind of radio operation equipment of LED display, and this radio operation equipment comprises receiving end device 102 and transmitting end device 104.Receiving end device 102 is installed on the LED display 200.
With reference to shown in Figure 1, Fig. 1 has disclosed the scheme of installation according to the receiving end device of an embodiment of the present utility model.Transmitting end device 104 comprises instruction inputting device 141, scrambler 142 and wireless launcher 143.In illustrated embodiment, instruction inputting device 141 comprises tracking ball 144 and nine key boards 145.Tracking ball 144 is used for the cursor of demonstration on the control LED display 200.Tracking ball 144 comprises ball and two shaft-position encoders corresponding to x direction and y direction that can freely promote with hand.Send the coding of corresponding x direction and y direction when ball rotates, the cursor on the control LED display moves with the moving direction of ball.Tracking ball 144 can also be pressed, and is equivalent to the function of left mouse button.Have nine operating keys on nine key boards 145, in one embodiment, wherein four is the direction operating key, and five remaining buttons are logic control keys, can carry out logical combination according to the program that sets in advance.In other embodiment, nine operating keys can all be the logic control keys, realize logical combination according to the program that sets in advance.The mode of button can be to press the Macintosh of singly-bound or two keys.Because the purpose of transmitting end device 104 is to realize simple feature operation, therefore for nine key boards 145, the combination of singly-bound and two keys has comprised abundant possibility, need not to support the key combination of greater number again.Instruction inputting device 141 receives the input instruction, the instruction of namely inputting by tracking ball 144 and nine key boards 145.Scrambler 142 is connected to instruction inputting device 141 and the input instruction is encoded, and the input instruction behind the coding is by wireless launcher 143 emissions.
With reference to shown in Figure 2, Fig. 2 has disclosed the scheme of installation according to the receiving end device of an embodiment of the present utility model.Receiving end device 102 is installed on the LED display 200.Receiving end device 102 is connected to the instruction input port 202 of LED display 200, and in one embodiment, the instruction input port 202 of LED display 200 is USB interface, and receiving end device 102 has USB plug receptacle 124.Receiving end device 102 comprises wireless receiver 121 and demoder 122.Wireless receiver 121 receives by the encoded input instruction of wireless launcher 143 emissions and offers demoder 122.The encoded input instruction of demoder 122 decodings restores original input instruction, and demoder 122 carries original input instruction to the instruction input port 202 of LED display 200.Displaying contents on the LED display 200 is inputted instruction in response to this, follows the movement of tracking ball and moves such as cursor, perhaps the function that shows corresponding to the logical combination key of nine key boards of LED display 200.In the embodiment shown in Figure 2, also have a pilot lamp 123 on receiving end device 102, the wireless communication status of pilot lamp 123 indication wireless launchers 143 and wireless receiver 121 receives at signal that pilot lamp 123 lights when normal.In one embodiment, the operating distance of wireless launcher 143 and wireless receiver 121 is 10 meters.
