The present invention proposes that a kind of WiFi turns the integrated interface circuit of Ethernet serial ports, comprising: WiFi control module 1, radio circuit 2 and main control module 3, the main control module 3 include Ethernet interface 4 and RS485/RS422 interface 5；Wherein, the 1 input terminal communication link of WiFi control module is connected to radio circuit 2, and 2 output end communication link of WiFi control module is connected to main control module 3.The circuit passes through protocol conversion and communication control, it is the conversion of wired Ethernet agreement and RS485/RS422 communication protocol by wireless WiFi communication protocol conversion, realizes control and data exchange of the existing Aerial Electronic Equipment based on airborne cable network to the following sensor device based on wireless network.
Description
Technical field
The invention belongs to aircraft communication field, a kind of WiFi realization for turning the integrated interface circuit of Ethernet serial ports is provided
Method.
Background technique
As the function of aircraft platform is continuously increased the promotion with function complexity, airborne computer system is in aircraft platform
In application constantly extension, thus realize aircraft platform to the acquisition of the data of sensor, airborne equipment and each layer of platform, control and
Management.Communication network between traditional airborne computer is wireline communication network, and the complexity of network layout is with network kind
Class, quantity, on line distance and the factors such as aircraft bay section physical environment and increase, furthermore sensor digitizing rate on aircraft platform
It improves rapidly, dispenses number of sensors in fuselage and be also continuously increased, cable network bring cable weight, volume sharply increase
Add, the maintenance workloads such as maintenance of cable network further increase.Application of the radio network technique on airborne, will reduce aircraft
Interior wiring reduces aircraft weight, improves the flexibility of airborne communication.
Summary of the invention
It is an object of the invention to propose that a kind of WiFi turns the implementation method of the integrated interface circuit of Ethernet serial ports, replace
Ethernet and serial communication in aircraft non-security-critical system, to solve in existing aircraft, wire communication bring system is multiple between machine
It is miscellaneous, it is difficult wiring, again, it is easy to damage the problems such as.
To achieve the above object, the present invention proposes that a kind of WiFi turns the integrated interface circuit of Ethernet serial ports, comprising: WiFi
Control module 1, radio circuit 2 and main control module 3, the main control module 3 include Ethernet interface 4 and RS485/RS422 interface
5；
Wherein, the 1 input terminal communication link of WiFi control module is connected to radio circuit 2, and 2 output end of WiFi control module
Communication link is connected to main control module 3.
Optionally, two processors built in the WiFi control module 1, a processor are used for wireless network management, lead to
Letter scheduling；Another processor is used for wireless network dedicated processes, which includes the TCP/IP of IPv4
Stack.
Optionally, two processors built in the main control module 3, a processor are used for system administration, communication scheduling；Separately
One processor is used for ethernet network dedicated processes, and the ethernet network application specific processor supports MII and RMII format.

Compared with prior art, the beneficial effects of the present invention are: the WiFi turns the integrated interface circuit of Ethernet serial ports,
Physically realize a kind it is wireless, 2 kinds of wired network interfaces integrated；The equipment such as more convenient sensor access onboard networks, nothing
Lead is needed, is easy to system extension, loss of weight, maintainability and reliability are higher.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment:
Following will be combined with the drawings in the embodiments of the present invention is clearly and completely described.
In conjunction with Fig. 1, the present invention provides a kind of WiFi integrated interface circuit for turning Ethernet serial ports, including radio circuit 2,
WiFi control module 1, main control module 3, Ethernet interface 4 and RS485/RS422 interface 5.
Wherein, radio circuit 2, WiFi control module 1 constitute radio communication circuit part.Radio circuit 2 include antenna and
Filter circuit.Filtered signal is linked into WiFi control module 1.It include two processors inside WiFi control module 1, i.e., it is main
Processor and wireless network application specific processor.Primary processor uses arm processor core, is responsible for wireless network management, communication scheduling
It is controlled with I/O interface；Wireless network application specific processor be integrated with WIFI agreement and TCP IP protocol stack.This example uses Ti company
CC3200 chip realizes WiFi control module 1.After powering on, CC3200 completes chip initiation first, then by SPI interface with
The SPI interface of main control module 3 is connected, and receives the control command that main control module 3 is sent, and sends through the acquisition of WiFi interface and pre- place
The data of reason.
Main control module 3 includes an arm processor, is responsible for the control and management of entire integrated interface circuit.This example is adopted
It is realized with the FH8812 of Fu Han company.After powering on, FH8812 completes chip initiation first, and then, FH8812 can run solid
The program of change sends control command to CC3200 by SPI interface, can also be received by Ethernet interface and be referred to from host computer
It enables, then sends control command to CC3200.FH8812 can also by RS485/RS422 interface 5 directly with existing wired biography
Sensor system is connected, receiving sensor data.FH8812 uploads the information of acquisition to host computer by Ethernet interface 4.
