The pending reception data of zero proof, then read the address bit of the reception data, treat that all of the port poll finishes unified root
Judge processing priority, software layer translation-protocol and transmission interface according to the reception data address position read before, be sent into afterwards
Data encoding is put into and corresponding sends that data buffer area etc. is to be sent, and address bit determines to send out at this time by corresponding application layer protocol
Send priority, software layer translation-protocol and transmission interface (such as Fig. 4).And the corresponding priority of data address, software layer conversion association
Negotiation transmission interface sets and is configured by computer end software by 485 interfaces and be stored in memory module.
Embodiment 2：Referring to Fig. 1-Fig. 3, a kind of to support a variety of communication bus conversion methods at the same time, the method is as follows, and 1）
CAN, SPI, RS485, Ethernet are respectively connected into the bus at scene；2）By 485 interfaces of computer and matching somebody with somebody for the equipment
Put interface connection, and using configuration software configure the corresponding priority in each interface data frame address position, software layer translation-protocol and
Transmission interface and four kinds of communication interface communications parameter configuration such as baud rates, master slave mode etc., and be stored in memory module, often
The secondary configuration parameter for powering on automatic loading last time；3）When some fieldbus sends data to interface, data frame passes through phase
The communication module answered enters arm processor, application layer protocol module, can be MODBUS according to the setting of interface and parameter configuration
Rtu protocol, CANopen agreements, ModbusTCP agreements or custom protocol, agreement number is obtained by corresponding driver
According to frame and it is decoded as virtual bus protocol data frame and is stored in the interface data buffer area of oneself；4）When core virtual bus
Program module monitors that receiving data buffer area has the address bit for being read first during data and receiving data frame in data buffer area, root
Judge which interface data frame conversion is sent to according to address bit, if there is the data frame that multiple communication interfaces receive to be sent at the same time
Same communication interface, data processing module will be judged according to address bit send priority, post processing prioritized data frame and put
Enter corresponding transmission buffer area, being defined after application layer protocol module monitors to the data frame sent in buffer area according to address bit will
Its transmission function for being encoded to corresponding data frame format and writing it in communication driver is sent.
In such scheme, when RS485 fieldbus sends data with MODBUS RTU application protocols to interface, data frame
Arm processor serial ports peripheral hardware buffer area is entered by RS485 transceiver modules, MODBUS RTU application protocol modules judge data frame
Whether meet protocol rule, do not meet discarding, meet, be decoded into virtual bus protocol data frame and be put into RS485 reception data
The reception data frame numerical digit of RS485 buffer areas is simultaneously added one by buffer area.When the priority block in virtual bus program is polled to
The reception data frame numerical digit of RS485 buffer areas just reads the address bit of the reception data when non-zero, after treating all of the port poll
Priority is judged according to data address position, if the data frame highest priority in RS485 order cachings area or the only number
Called switch target agreement is then determined according to information of address bit according to frame, it is assumed that define judgement herein according to address bit and be converted to
The ModbusTCP agreements of Ethernet interface then place data into Ethernet interface and send data buffer area and call ModbusTCP
Agreement is encoded and sent.
Similarly RS485 general line systems CAN bus, RS485 general line systems spi bus, RS485 general line systems CAN bus and
Spi bus and Ethernet, CAN bus conversion RS485 buses, CAN bus conversion spi bus, CAN bus conversion Ethernet etc.
It is all similar to the above embodiments.

Interface, data processing module will be judged according to address bit send priority, post processing prioritized data frame and be put into corresponding hair
Buffer area is sent, is defined after application layer protocol module monitors to the data frame sent in buffer area according to address bit and is encoded to phase
The data frame format the answered and transmission function for writing it in communication driver is sent.
