Specific embodiment
Embodiment one:
Below in conjunction with attached drawing, invention is further described in detail.
It referring to Figures 1 and 2, is a kind of multi-protocol data integral communication device based on serial communication disclosed by the invention,
Shell 1 including rectangle, the data processor in shell 1 and eight inlet interfaces that 1 same side of shell is set
2, an outlet interface 3 and a configuration interface 4.Wherein data processor is the single-chip microcontroller with data integration processing function,
It is herein preferably the single-chip microcontroller of STM32F103VCT6 model.There are a variety of receptions corresponding with communication protocol in data processor
Subfunction and output subfunction, communication device connect host computer by configuring interface 4, and are each inlet interface by host computer
2 and outlet interface 3 configure it is corresponding receive subfunction, to realize that same interface adapts to receive various communications protocols data.
In binary data transmission mode as an example, such as communication protocol A are as follows: 1 start bit, 8 data bit, 1 bit parity school
Test position and 1 stop position；
Communication protocol B are as follows: 1 start bit, 4 are data bit, 1 bit-errors check bit and 1 stop position；
Communication protocol C are as follows: 1 start bit, 1 bit check position, 8 data bit and 1 stop position.
Then when receiving the detection data using communication protocol A output detection data, corresponding inlet interface 2 is received into number
According to mode be configured to the reception subfunction of corresponding communication protocol A, and extracting 2-9 data is detection data, and by out
Line interface 3 is to export the corresponding communication protocol transmission mode output of subfunction.
In order to enable outlet interface 3 to export the received data of multiple inlet interfaces 2, the corresponding communication protocols of output subfunction
View code successively includes a start bit, two stop positions and the data bit between start bit and stop position, and each group
The data of data bit correspond to the inlet wire data of single inlet interface 2 and configured with partition positions.Wherein start bit " 1 " effectively, stops
Effectively, partition position uses four partition positions for position " 01 ", and partition position " 0000 " is effective.
As three inlet interfaces 2 are respectively configured as of reception corresponding to communication protocol A, communication protocol B and communication protocol C
Function, data code are as follows:
1 11010110 1 1；
1 1101 0 1；
1 1 11011011 1；
Then three 2 received detection datas of institute of inlet interface are respectively as follows: " 11010110 ", " 1101 " and " 11011011 ", use
The mode that the corresponding communication protocol of output subfunction exports three groups of data is answered are as follows:
1 11010110 0000 1101 0000 11011011 0000 01；
Wherein, in order to increase the safety in data transmission procedure, verification is added in the corresponding communication protocol of output subfunction
Position is the customary means of this field, and in the declared range of the present embodiment, details are not described herein.
The mode for using host computer to configure reception subfunction for each inlet interface 2 is as follows:
The reception subfunction for such as needing to call is printf(a), a is the data received by printf subfunction, then interface
Reception data mode are as follows:
Int main()
Printf(a);return a;}
The received data of each inlet interface 2 are obtained by " a " value that each inlet interface 2 returns.
Further, data processor is also connected with HART communication module, crosses HART communication module all and realizes communication dress
The regional networking set reduces the cost of layout of the device of communication in order to reduce the quantity of on-scene communication line.
Further, read-write interface 5 is additionally provided on shell 1, staff can be realized by read-write interface 5 to data
Manage the update of device internal processes.
It is first each by configuration device by the above content it is found that when needing to carry out data acquisition to plurality of devices
Outlet interface 3 and inlet interface 2 configure the subfunction for sending and receiving data, enable and pass through the data that inlet interface 2 enters
Enough to be received in a manner of correspondingly received subfunction, the appearance data of each outlet interface 3 can be accordingly to export the side of subfunction
Formula output data is exported the detection device detection data of various communications protocols by unified communication mode to realize.
Embodiment two:
It is in place of the present embodiment and the difference of embodiment one:
The corresponding communication protocol code of output subfunction successively include a start bit, a flag bit, a stop position and
Data bit between flag bit and stop position.Wherein effectively, effectively, flag bit is provided with stop position " 01 " start bit " 1 "
Three, and the value of flag bit corresponds to the label of corresponding inlet interface 2.
Embodiment three:
It is in place of the present embodiment and the difference of embodiment one:
As shown in figure 3, communication device includes display screen 6 for showing each interface communications protocol and cooperates with display screen 6
Configuration button 7, display screen 6 is located at communication device upper surface, so that practical personnel can intuitively observe that communication device is each
The communication protocol of interface configures.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
