Abstract

The invention relates to the technical field of data wireless transparent transmission and discloses a system capable of achieving ad hoc network serial port data wireless transparent transmission. The system comprises a device used for achieving ad hoc network functions, a device used for achieving universal serial bus (USB) serial port conversion functions and a power supply device, wherein the device used for achieving ad hoc network functions, the device used for achieving USB serial port conversion functions and the power supply device are connected sequentially. By the aid of the system, the problems that only point-to-point communication of existing products is achieved on and additional power supplies are required to be installed are solved. A CC2530 chip is used, a USB port of the CC2530 chip is converted to a serial port through a CP2102 chip, and the CC2530 chip is in communication with a host computer. The volume is small, functions such as data transmission, ad hoc networks and self-routing are achieved, the transmission distance is long, the additional power supply is not required, and the transmission of large data volume is completed.

Description

Technical field [0001] The present invention relates to the technical field of data wireless transparent transmission, in particular to a system for realizing wireless transparent transmission of serial port data in an ad hoc network. Background technique [0002] The existing serial port transparent transmission products are basically nRF series products based on Bluetooth or wireless radio frequency chips, which are composed of a control chip MCU (micro control unit), a wireless module (similar to nRF series chips), and a serial port module. It can play the function of serial port transparent transmission in point-to-point and short distance. The following are two typical existing products: [0003] The combination product of MUC and nRF series wireless chip can only complete point-to-point communication, and the communication distance is relatively short, often only within 50m in an open outdoor situation. [0004] When the Bluetooth wireless transparent transmission product is ...
