Serial server, wind power communication system and bus communication system

Abstract

The embodiment of the invention discloses a serial server, a wind power communication system and a bus communication system. The serial port server comprises a processor, a PHY chip, a WIF I module, a network transformer, a first pin header, a second pin header, a third pin header and a fourth pin header. An MAC module is integrated in the processor, the MAC module is connected with a control unit of the processor through an AHB bus, the MAC module is connected with one end of the PHY chip through an RM I interface, and the other end of the PHY chip is connected with one end of the network transformer. The other end of the network transformer is connected with the first pin header. The WIF I module is connected with a first serial interface of the processor, an input / output interface of the processor is connected with a second pin header, an analog-to-digital conversion interface of the processor is connected with a third pin header, and a second serial interface of the processor is connected with a fourth pin header. According to the serial server provided by the embodiment of the invention, the data can be received and transmitted through the Ethernet and the WIF I, the data transmission convenience is improved, and the data transmission cost is reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communication, and in particular to a serial port server, a wind power communication system, and a bus communication system. Background technique [0002] The serial port server is a device that provides the serial port to network function, which can convert the RS-232 / 485 / 422 serial port into a TCP / IP protocol network interface, and realize the data bidirectional between the RS-232 / 485 / 422 serial port and the TCP / IP protocol network interface Transparent transmission, or support MOUBUS protocol two-way transmission, so that the serial device can immediately have the TCP / IP network interface function, connect to the network for data communication, and extend the communication distance of the serial device. In the traditional serial server, it is mostly the conversion between Ethernet and serial port. This type of serial server cannot allow users to choose between Ethernet and W...

Problems solved by technology

However, the CAN bus communication mode is adopted between the electronic control units of the electric bus, but the signal transmitted by the CAN bus is not compatible with the industrial Ethernet, so in order to realize the wireless two-way communication between the electric vehicle and the charging bow, it is necessary to introduce a new Communication Systems
