Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] The present invention proposes a method of using the N-ISDN UNI interface technology of the telecommunication network, which puts the communication data to be transmitted by multiple serial ports into the sending data frame of the UNI interface, and then transmits the sending data frame to the opposite end through a twisted pair. Therefore, it is possible to realize a multi-serial port transmission technology that has the advantages of low cost, strong a...

Abstract

The invention belongs to the field of computer communication, and discloses a multi-serial data remote transmission device and method, which can be applied to realizing lower cost, stronger antijamming capability, bi-directional 144kbps transmission rate, and 3-5km transmission distance. The remote transmission device comprises a twisted-pair, and two RS232 to UNI interface modules respectively connected to two ends of the twisted-pair, wherein the RS232 to UNI interface modules are used for multiplexing RS232 serial signals of multiple data serial ports into one path of UNI interface signal, or branching the one path of UNI interface signal into the multiple RS232 serial signals; a pair of twisted-pair is used for transmitting the one path of UNI interface signal.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a long-distance transmission device and method for multi-serial port data. Background technique [0002] In the case of using a high-power radio station, since the radio station’s transmission power is large, up to hundreds of watts, in order to reduce the interference of the radio station’s transmitter to its receiver, it is usually necessary to place the transmitter at a distance of 3~ Therefore, high-power radio stations need a multi-channel radio with low cost, strong anti-interference ability, convenient erection, and can support voice, data and other services at the same time, and can achieve a transmission distance of 3-5 kilometers. Serial port transmission technology. [0003] At present, the communication means that can enable the serial port to achieve a longer transmission distance mainly include: RS485 bus technology, xDSL technology and wireless data transmiss...
