Embodiment
Can't carry out the problem of efficient management to many cross-screens in order to solve current cross-screen control system, present embodiment provides a kind of cross-screen network control system.Below in conjunction with specific embodiment, the cross-screen network control system is specifically described.
Please refer to Fig. 1, the cross-screen network control system that present embodiment provides, comprise computing machine 110, radio frequency (RF, Radio Frequency) sending module 120, several Receiver Modules 130 and control card 140.
In the present embodiment, radio frequency sending module 120 is connected by USB interface with computing machine 110.Computing machine 110 can directly transfer to radio frequency sending module 120 by No. ID (being mainly used in guaranteeing data only are sent to the cross-screen of certain expection for No. ID) and data.
Between radio frequency sending module 120 and several Receiver Modules 130, in the radio communication mode, communicate by letter.When No. ID of receiving that computing machine 110 sends of radio frequency sending module 120 and data, radio frequency sending module 120 can transfer to several Receiver Modules 130 in the radio communication mode by No. ID and data.
Each Receiver Module 130 is equipped with unique numbering, and control card 140 of the equal separate connection of each Receiver Module 130.When radio frequency sending module 120 is seen No. ID and data off with radio communication mode side, at first whether Receiver Module 130 detect No. ID and mate with numbering separately, if mate data that received RF sending module 130 sends transfer data to control card 140, if do not mate can not receive data.Receive the coupled cross-screen of Data Control that the control card 140 of data is sent according to computing machine immediately, make cross-screen show corresponding information.From said process, we can see, cross-screen network control system in present embodiment, can guarantee that data only are sent to the cross-screen of certain expection, thereby realize many cross-screens are carried out to network management control, that is realize many cross-screens are managed efficiently.
Please refer to Fig. 2, in the present embodiment, control card 140 comprises that STM32(STM32 refers to 32 series microprocessor chips of STMicw Electronics) microprocessor 141 and the serial port circuit 142, Flash storer 143, light sensation circuit 144, temperature sensor 145, cross-screen that are connected in STM32 microprocessor 141 drive interface 146, JTAG(Joint Test Action Group, joint test behavior tissue) programming port 147 and clock chip 148.
Under the control of STM32 microprocessor 141, light sensation circuit 144 can be adjusted voluntarily according to the ambient light line strength brightness of cross-screen, such as at night, the brightness that light sensation circuit 144 can be controlled cross-screen brightness by day lower than it, thus saved certain electric energy.
Under the control of STM32 microprocessor 141, temperature sensor 145 can obtain ambient temperature.Thereby cross-screen also can show Current Temperatures information.
JTAG programming port 147 is upgraded the program of STM32 microprocessor 141 inside for outer computer.Due to the variation of actual needs, the program of STM32 microprocessor 141 inside may need corresponding change or upgrading, at this time by JTAG programming port 147, just can reach quickly and easily the purpose of update routine.
Please refer to Fig. 3, cross-screen comprises several LED modules, and these several LED modules are arranged in " ten " character form structure.In traditional cross-screen control system, several LED modules are controlled by single signal usually, how out-of-date when LED module quantity, only depend on a road signal controlling can't meet the requirement of signal high-speed transfer, the low sudden strain of a muscle screen problem caused of refresh rate may appear.In the present embodiment, we are divided into two groups by these several LED modules, and several LED modules in every group connect with series system, and signal input 1 and signal input 2 that every group of LED module produced by STM32 microprocessor 141 are respectively controlled.This two paths of signals transmits simultaneously, and due to the quantity reduction of every group of LED module series connection, the complete time used of whole data transmission of cross-screen at least reduces half, thereby has improved the refresh rate of cross-screen, has solved to a certain extent sudden strain of a muscle screen problem.
In the present embodiment, the control employing ON time of cross-screen pixel gray scale is controlled to method, setting minimum ON time is T, T of the every increase of pixel ON time, and the gray scale of this pixel performance just increases one-level.The binary number representation of one 4 for the gradation data of pixel, the gray shade scale of pixel can reach 16 grades like this.Please refer to following form:
| Gradation data | Gray shade scale | ON time |
| 0000 | 1 | 0T |
| 0001 | 2 | T |
| 0010 | 3 | 2T |
| 0011 | 4 | 3T |
| 0100 | 5 | 4T |
| 0101 | 6 | 5T |
| 0110 | 7 | 6T |
| 0111 | 8 | 7T |

| 1100 | 13 | 12T |
| 1101 | 14 | 13T |
| 1110 | 15 | 14T |
| 1111 | 16 | 15T |
ON time, gray shade scale are corresponding with gradation data, as long as computing machine 110 sets gradation data, just control card 140 can be controlled the ON time of each pixel of cross-screen, thereby control the gray scale of each pixel, and the content that cross-screen is shown is abundanter.
Above-mentioned cross-screen network control system can guarantee that data only are sent to the cross-screen of certain expection, has realized many cross-screens are carried out to network management control, that is has realized many cross-screens are managed efficiently.
In addition, adopt the LED module after the multiple signals control packet, can improve the refresh rate of cross-screen, solved to a certain extent sudden strain of a muscle screen problem.
Simultaneously, the gray shade scale of the pixel of cross-screen can reach 16 grades, has greatly enriched the content that cross-screen shows.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
