Passive communication protocol translator

Abstract

The invention relates to a passive communication protocol translator. The passive communication protocol translator comprises an intelligent processor module supporting an open-sourcing gcc compiler and an arduino integrated development environment, a memorizer, a serial port self-powered source transformation module, an RS-232 module, an RS-485 module and an anti-thunder module, wherein the intelligent processor module is arranged on a circuit board, the memorizer is connected with the intelligent processor module, and the anti-thunder module is connected with the RS-232 module and the RS-485 module. An RS-232 interface of the RS-232 module and an RS-485 interface of the RS-485 module respectively serve as an output interface or an input interface of the translator, the serial port negative voltage is converted into the stable 3.3-volt positive voltage to be output through the serial port self-powered source transformation module, then the 3.3-volt positive voltage is output to the intelligent processor module, and the anti-thunder module and the RS-485 module are connected to absorb an instantaneous high voltage. The passive communication protocol translator has the advantages of being small in size, free of power supply, wide in application range and the like, and the field installation and construction are easy.

Description

technical field [0001] The invention relates to a converter, especially a passive communication protocol translator. Background technique [0002] With the development of computer technology, a variety of serial ports of different standards have been born, and the serial ports of different standards cannot communicate directly. Therefore, when it is necessary to communicate between serial ports of different standards, the signals need to be converted. [0003] At present, industrial computers or programmable controllers are generally used as communication protocol translators, which first convert the received signals to meet the standards of the receiving interface, and then output them to the receiving interface to realize the translation of communication protocols. [0004] However, the current communication protocol translators have the disadvantages of complex systems, large volumes, and high power consumption, which lead to complex applications and high costs, making it...
