Abstract

The invention relates to a data receiving, storing and forwarding device suitable for various ports, belongs to the field of communication electronics, and aims to solve the problem that the conventional data receiving, storing and forwarding device has no commonality. An output end of a receiving port circuit of the device is connected with a port selection circuit, wherein an RS232 serial port of the port selection circuit is connected with an RS232 serial port of an FPGA through an RS-232 unit; an RS422 serial port of the port selection circuit is connected with an RS422 serial port of the FPGA through an RS-422 unit; and an RS485 serial port of the port selection circuit is connected with an RS485 serial port of the FPGA through an RS-485 unit; a control and output end of the FPGA is connected with a controlled end of the port selection circuit; a data storage, input and output end of the FPGA is connected with an input and output end of a storage unit; and a forwarding or storing control signal output end of the FPGA is connected with a forwarding or storing control signal input end of a forwarding unit.

Description

technical field [0001] The invention relates to a data receiving, storing and forwarding device suitable for ports of various serial bus communication modes, and belongs to the field of communication electronics. Background technique [0002] At present, there are many kinds of devices for receiving, storing and forwarding data. As far as its receiving method is concerned, it includes two types of wired reception and wireless reception. Wireless reception is generally weak in anti-interference, and there are various types of wired data reception. Common ones include RS-232 bus, RS-422 bus, RS-485 bus, and CAN bus. Wait for the receiving method. In terms of storage methods, the memory is generally realized by storage media such as FIFO, SRAM, SDRAM, ROM, FLASH, and solid state disk. In terms of forwarding methods, serial communication is generally used, and the commonly used ones are USB bus, RS-422 bus, and RS-485 bus. [0003] Summarize and summarize the currently existi...
