Abstract
The utility model provides a signal transmission structure of a multi touch screen, which comprises a first network interface, a second network interface, a signal converting unit and a universal serial bus (USB) port. The multi touch screen comprises a serial data interface which is connected with the first network interface through an RS232 serial data line, one end of the data line is connected with the second network interface, and the other end of the data line is connected with the USB port. The first network interface is connected with the second network interface through a reticle, and the USB port is connected with a computer USB port. The signal transmission structure uses the characteristics of serial signals which are long in transmission range and reliable in transmission, enables the multi touch screen to output the serial signals, and enables the serial signals to be converted into USB signals and then connected with the computer, so that connection distance between a host machine of the multi touch screen and the computer is prolonged, and reliability of data transmission is improved.
Description
Technical field
The utility model relates to a kind of transmission structure of signal, particularly a kind of signal transmission structure with multi-point touch panel of extended line.
Background technology
Between multi-point touch panel of the prior art and the computer all is that common USB interface is connected usually, and the gauged distance between multi-point touch panel and the computer is 5 meters, therefore, when so long distance connects, must use high-quality usb data line.Yet, even if use high-quality usb data line, when length increases, also can the problem that usb signal is made mistakes take place because of the electricity shortage of multi-point touch panel (particularly infrared screen).
The utility model content
The purpose of the utility model provides that a kind of simple in structure, dependable performance, cost are low, the signal transmission structure of the multi-point touch panel of long transmission distance.
For solving the problems of the technologies described above; The utility model provides a kind of signal transmission structure of multi-point touch panel; It is characterized in that; Comprise first network interface, second network interface, signal conversion unit and USB interface, said multi-point touch panel comprises serial data interface, and said serial data interface is connected with said first network interface through the RS232 serial data line; One end of said signal conversion unit is connected with said second network interface, and the other end of said signal conversion unit is connected with said USB interface; Be connected through netting twine between said first network interface and said second network interface, said USB interface is connected with the USB interface of computer.
Further, said first network interface and second network interface all are the RJ45 sockets.
Further, said netting twine is to surpass five types of netting twines.
Further, said signal transmission structure also comprises power interface, and said power interface is connected with the 5V/500mA power supply.
Further, said multi-point touch panel is the multiple spot infrared touch panel.
The utility model utilizes serial signal long transmission distance, transmission reliable characteristics; Make multi-point touch panel output serial signal; Be connected with computer after converting serial signal into usb signal then; Thereby increased the distance of the line between multi-point touch panel main frame and the computer, and improved reliability of data transmission.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Fig. 1 shows the structural representation of the signal transmission structure of the multi-point touch panel in the utility model.As shown in Figure 1; The signal transmission structure of said multi-point touch panel comprises first network interface 4, second network interface 6, signal conversion unit 7 and USB interface 8; Said multi-point touch panel 1 comprises serial data interface, and said serial data interface is connected with said first network interface 4 through RS232 serial data line 3; One end of said signal conversion unit is connected with said second network interface 6, and the other end of said signal conversion unit 7 is connected with said USB interface 8; Be connected through netting twine 5 between said first network interface 4 and said second network interface 6, said USB interface 8 is connected with the USB interface (not shown) of computer.Therefore, the output data of multi-point touch panel main frame is earlier through the pattern output of RS232 level with serial, adopts the signal of serial output can realize the signal transmission of 15 meters distance, and data are made mistakes and the probability of losing is very little; Then, this signal is transferred to said signal conversion unit through network, and said signal conversion unit converts the serial data that it receives into usb signal, to realize communicating by letter between multi-point touch panel and the host computer, with the said multi-point touch panel of normal use.Preferably, said multi-point touch panel is the multiple spot infrared touch panel.
Preferably, said first network interface 4 and second network interface 6 are female sockets of RJ45 socket, particularly RJ45.Preferably, said netting twine 5 is to surpass five types of netting twines, and the two ends of said netting twine 5 are crimped with 8 core crystal heads respectively, uses netting twine as connecting line, have wiring and characteristics easy to make, and the antijamming capability of netting twine is relatively good.Preferably, said netting twine is the parallel netting twine of making by the 568B standard.
Preferably, said signal transmission structure also comprises power interface 2, and preferably, said power interface 2 is connected with independent 5V/500mA power supply, to solve power supply owing to the voltage that long Distance Transmission produces reduces the problem that causes the multi-point touch panel electricity shortage.
The utility model utilizes serial signal long transmission distance, transmission reliable characteristics; Make multi-point touch panel output serial signal; Be connected with computer after converting serial signal into usb signal then; Thereby increased the distance of the line between multi-point touch panel main frame and the computer, and improved reliability of data transmission.
