Communication adapter

Abstract

The invention belongs to the technical field of electronics, and particularly relates to a communication adapter, which comprises a single chip microprocessor, a memory, a real-time clock, an uplink communication terminal and a downlink communication terminal, wherein the single chip microprocessor is provided with two asynchronous serial communication ports and a capacitor, the capacitor is used as a resetting circuit of the single chip microprocessor, the uplink communication terminal is connected with the corresponding pin of first receiving and transmitting pins of one asynchronous serial communication port of the single chip microprocessor by a first sending and transmitting device, the downlink communication terminal is connected with the corresponding pin of second receiving and transmitting pins of the other asynchronous serial communication port of the single chip microprocessor by a second sending and transmitting device, and a data line of the memory and a clock line of the real-time clock are respectively connected with the corresponding pins of the single chip microprocessor. The communication adapter has the advantages that the existing electric leakage protector communication protocol is converted into the industrial standard of Residual Current Action Protector Communication Protocol, the replacement of the protector is not needed, and the waste is reduced.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a communication adapter. Background technique [0002] The power supply department puts the safety and reliability of power grid operation in an important position, and the installation of leakage protectors has been widely promoted and applied as one of the effective protection measures to ensure the safe operation of rural power grids. With the development of informatization and the need to build a smart grid, intelligent and communicable requirements are put forward for the leakage protector used in the grid. For this reason, the country issued a unified industry standard "Residual Current Action Protector Communication Protocol", which standardized and unified the communication protocol between the leakage protector and the distribution transformer acquisition terminal. Before the release of industry standards, the communication protocols of leakage protectors operating ...

AI Technical Summary

Problems solved by technology

Before the release of industry standards, the communication protocols of leakage protectors operating in rural power grids are various and defined by each manufacturer; in addition, the storage space and hardware resources of leakage protectors are also insufficient (such as lack of real-time clock)
