Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
The embodiment of the present application discloses a kind of board equipment, meets remote AccessPort demand.
Referring to fig. 2, a kind of structure chart of board equipment disclosed in the embodiment of the present application, as shown in Fig. 2, including board 100
Turn radio receiving transmitting module 200 with serial ports;The board is provided with board serial port connector 101, and the board 100 passes through the plate
Card serial port connector 101 turns radio receiving transmitting module 200 with the serial ports and is connected.
In specific implementation, serial port connector 101 can be reserved when board 100 designs, serial ports is turned into radio receiving transmitting module 200
It is inserted on the serial port connector 101 of board 100, that is, realizes the imagination target that serial ports is converted into wireless telecommunications, computer end is opened
Wirelessly it can be used later with wireless module docking.
Board equipment provided by the embodiments of the present application turns radio receiving transmitting module by serial ports and replaces serial ports turn in the prior art
The interconnecting module of USB port, wired connection become being wirelessly connected, and reduce the complexity of connection, avoid since connecting line is more, connection is closed
Time cost caused by system is complicated, can simplify the process of AccessPort.In addition, being wirelessly connected can prop up compared to wired connection
Hold longer-distance debugging demand.
The specific structure that serial ports turns radio receiving transmitting module 200 is described in detail below.The serial ports turns radio receiving transmitting module packet
Include bus structures, processing unit, wireless transmitter and multiple serial port devices;
The serial port device is connected with the board serial port connector, for receiving the board serial port connector transmission
Rs 232 serial interface signal;
The processing unit is connected by the bus structures with the serial port device, for defeated according to the rs 232 serial interface signal
The identifiable M signal of the wireless transmitter is to the wireless transmitter out;
The wireless transmitter is connected with the processing unit, for the M signal to be converted to wireless signal simultaneously
It sends.
Preferably, serial port device can be specially RS485 serial port device, and bus structures can be specially the total knot of RS485
Structure.The particular number of RS485 serial port device is not unique, can be adjusted according to actual needs.RS485 bus is that one kind is more
The communication interface of point, differential data transmission, have it is succinct flexibly, hardware interface is simple, software is easily realized, sexual valence is relatively high, biography
The advantages that defeated distance is farther out, the bit error rate is lower, strong antijamming capability.RS485 communication is half duplex communication, is sent and received shared
Same physical channel.
