Multipurpose wireless data converter

Abstract

The invention relates to a converter, in particular to a multipurpose wireless data converter. The multipurpose wireless data converter comprises a converter body; the converter body is provided with a power supply output interface and a variety of data interfaces; the converter body is internally provided with a CPU (Central Processing Unit), and a WiFi (Wireless Fidelity) module and a serial port module which are in communication connection with the CPU respectively; the converter body is also provided with an external USB (Universal Serial Bus) module; the CPU adopts a PowerPC QorIQ series communication processor; the WiFi module adopts a wireless router chip which is provided with a wireless interface and integrated with an internal configurable Ethernet switch; the WiFi module communicates with the CPU by virtue of the Ethernet switch; the serial port module adopts an FPGA (Field Programmable Gate Array) chip integrated with a plurality of various serial buses; the USB module adopts a USB peripheral control unit; the CPU, the WiFi module and the serial port module are respectively in communication connection with respective corresponding data interfaces. The multipurpose wireless data converter disclosed by the invention integrates the serial port to WiFi function, the wireless router function and the ARINC429 avionics bus wireless transmission function, and has the advantages of large interface number, interface concentration, high equipment generality and the like.

Description

technical field [0001] The invention relates to a converter, in particular to a multipurpose wireless data converter. Background technique [0002] The ARINC429 bus protocol is an avionics bus proposed by the American Aviation Electronics Engineering Committee (Airlines Engineering Committee) in July 1977. It is one of the most mainstream bus protocols used by many aircrafts today. [0003] In the past, aviation equipment used different types of aviation buses (such as ARINC453, ARINC461 / 568, ARINC573, ARINC575, ARINC582), and it was difficult to be compatible with each other. Modern aircraft electronic systems require that all airborne aviation equipment use a unified aviation bus to facilitate system integration. ARINC429 forms a specification under this need. [0004] The definition of electronic flight bag (EFB) originated in the late 1970s. The original core purpose was to replace heavy paper documents. Today, the electronic flight bag system is no longer a simple dig...

AI Technical Summary

Problems solved by technology

The current ARINC429 bus data is mainly transmitted by wire, such as using: 429 to USB, 429 to PCI and other devices. These devices are cumbersome to use and need to be connected to the computer many times to adjust parameters and set the working interface, and the intelligence is extremely low.

Moreover, the wired transmission method will cause inconvenience and hidden dangers in many aspects such as transmission distance, installation wiring, and uniform equipment interface standards. Even wireless expansion through wired methods will greatly increase the space occupied by the equipment and reduce the degree of integration.

At the same time, it is necessary to develop and install the driver when using the USB cable method, which increases the burden of equipment operation and causes unnecessary software development work.
