Embodiment Construction

[0042] A multi-channel communication sharing device and method of the present invention will be explained and illustrated in detail below in conjunction with the accompanying drawings.

[0043] Such as Figures 1 to 17 As shown, the present invention discloses a multi-channel communication sharing device, which is used to realize the communication function between a communication terminal and other communication terminals using different communication interfaces under the same protocol. The multi-channel communication sharing device mainly includes a control converter For each interface, for example, the control converter includes a first signal control isolation unit, a first signal level conversion unit, etc., and the above-mentioned interfaces include an RS485 interface, a UART interface, a WIFI interface, and the like. The invention can ensure that the communication signal can only be transmitted in one direction: from the output end of any interface to the input end of othe...

Abstract

The invention discloses a multi-channel communication sharing device and method. The device includes an RS485 interface, a UART interface, a WIFI interface and a first signal control isolation unit, and the output end of the RS485 interface and the first input end of the first signal control isolation unit Connection, the output end of the UART interface is connected with the second input end of the first signal control isolation unit, the output end of the first signal control isolation unit is connected with the input end of the WIFI interface; the first input end of the first signal control isolation unit is connected to A forward diode is connected in series between the output terminals, and a forward diode is also connected in series between the second input terminal and the output terminal of the first signal control isolation unit; the method utilizes the above-mentioned device to share the communication signal. Compared with the prior art, the present invention not only can connect different interfaces in parallel to meet the requirement of multiple terminals using different communication interfaces in parallel, but also ensures the conversion efficiency of communication signals and effectively reduces cost input.

Description

technical field [0001] The present invention relates to the technical field of data communication interface, more specifically, the present invention is a multi-channel communication sharing device and method. Background technique [0002] There are various communication methods at present, and various communication interfaces based on the same protocol emerge in endlessly, and multiple terminals using different communication interfaces based on the same protocol sometimes need to be used in parallel, especially in industrial communication. This phenomenon is more common; However, due to mutual interference and different electrical characteristics between the interfaces, various interfaces cannot be directly connected in parallel, which requires a communication signal control conversion device between various interfaces to ensure reliable signal transmission, non-interference with each other, and corresponding The interface electrical characteristics match. [0003] At pres...
