Detailed description of the invention
The attached drawing constituted part of this application is used to provide further understanding of the present invention, schematic reality of the invention
It applies example and its explanation is used to explain the present invention, do not constitute improper limitations of the present invention.In the accompanying drawings:
Fig. 1 is the method flow diagram of PORT COM connection method according to an embodiment of the present invention；
Fig. 2 is the method flow diagram of application software connecting communication according to an embodiment of the present invention；
Fig. 3 is the structural block diagram of PORT COM attachment device according to an embodiment of the present invention.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, right below with reference to embodiment and attached drawing
The present invention is described in further details.Here, exemplary embodiment and its explanation of the invention is used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
When in order to solve the connection of existing communication software using computer terminal port, user can not determination port numbers and wave
Special rate and lead to a possibility that repeatedly selecting, influencing friendly that software uses is problem, proposes a kind of communication in this example
Connection method can be automatically identified in PORT COM and connect, and avoid the problem of wasting time caused by the blind choosing of user,
The user experience is improved.
Specifically, may include steps of as shown in Figure 1, provide a kind of PORT COM connection method:
Step 101: obtaining port list and the communication baud rate list of target device；
Wherein, above-mentioned target device can be computer, and communication software can trigger automatic connection after being installed into computer
The operation of port.
It may include: that the selection target is set specifically, obtaining port list and the communication baud rate list of target device
In standby arbitrary port access target bus；Automatically the target device is detected, the port list and the communication wave are generated
Special rate list.
Step 102: according to the port list, determining target port；
Step 103: according to the communication baud rate list, determining the baud rate of the target port；
Step 104: determining baud rate being set with the target port, is communicated.
In upper example, port list and the communication baud rate list of target device are obtained, port list is then based on, determined
Target port, and according to communication baud rate list, the baud rate of target port is determined, so as to realize target port and baud
Rate automatically determines, and solves existing software and needs user's selection port number, inefficiency caused by setting baud rate
Problem has reached software automatic identification port and baud rate, to realize the technical effect connected automatically.
It, can be by the way of determining one by one, that is, can be according to list in order to determine target port from port list
Sequence, port is confirmed whether to be available one by one.I.e., it is possible to identify whether the port in the port list is beaten one by one
It opens, using the port in the open state recognized as target port.After selected target port, wave can be selected for it
Special rate, if suitable baud rate can also be determined, just using the port as target port, if being not in open shape
State, or determine less than suitable baud rate, then determining that whether next port can be used as target port, that is, by
One determines whether port can be used.
When determining the baud rate of port based on port, it can execute in accordance with the following steps:
S1: select the bit rate in communication baud rate list as target bit rate one by one；
S2: the bit rate that the target port is arranged is the target bit rate；
S3: it determines in the case where setting the target bit rate for the target port, the quality of data of communication data
Whether preset requirement is met；
S4: in the case where being determined for compliance with preset requirement, the target bit rate is determined as to the ratio of the target port
Special rate.
When specific implementation, above-mentioned preset requirement can be whether determining data frame format is correct, or really
Determine whether data frame format is preset target data format.This also has relationship with the position of software and identity, if software is
Host computer, if software is not host computer, mainly receives data, therefore, for software then mainly sending data
Whether it is host computer, different determination logics can be used, for example, can judge in the following way:
1) application software be host computer in the case where, send order frame data, listen to transmission order frame data whether
Meet the preset object format for replying frame data；
2) in the case where application software non-host computer, bus mode data determine whether the frame head of bus data meets
Preset data format.
The above method is illustrated below with reference to a specific embodiment, it should be noted, however, that the specific implementation
Example does not constitute an undue limitation on the present application merely to the application is better described.
In this example, a kind of application software is proposed to connect to the automatic identification of the PORT COM and baud rate used and automatically
Method is connect, without artificial selection setting PORT COM and baud rate, so as to effectively promote the friendly of software interactive.
As shown in Fig. 2, PORT COM automatic identification and the method for connection may include:
S1: in the available arbitrary port access data/address bus of selection computer；
S2: application software is opened；
S3: software program detects local computing automatically, generates port list port [i] and common communication baud rate list
baud[j]。
S4: judging the state of each port in port list one by one in order, determine each port whether opened with.
If opened with, execute S5；Otherwise, S6 is executed；
S5: next (i+1) a port numbers of selection judge whether to have exceeded port list range, that is, judge whether to have examined
All existing ports of computer are surveyed.If detected, S13 is executed, S4 is otherwise executed；
S6: baud rate value is arranged according to baud rate list one by one, executes S7；
S7: judge software whether be communication host computer (whether be host computer when developing software it is determined that), if it is
Host computer then executes S11, otherwise, executes S8；
S8: listening to and receive bus receipt, executes S9；
S9: judging whether received data frame head meets the object format of agreement, if met, executes S14；Otherwise it holds
Row S10；
S10: a kind of lower (j+1) baud rate of selection judges whether to be more than baud rate list range, that is, judge whether
It attempts to set up all baud rate parameters in list.If gone beyond the scope, S5 is executed；Otherwise S6 is executed；
S11: order frame data are sent according to communications protocol, execute S12；
S12: interception data judges whether it is the reply frame data for meeting protocol target format, if it is, executing S14；
Otherwise S10 is executed；
S13: automatic identification port and connection failure prompt user's inspection computer terminal port or software program baud rate list are
The no target baud rate value comprising communication need.
S14: automatic identification port numbers, baud rate and successful connection stop automatic identification step, and software enters use.
Through the above scheme, in subsequent communications software development, software can be realized, computer terminal port used is carried out certainly
The purpose of dynamic identification and the setting of baud rate, eliminates user's manpower operation setting and selection mismatches and needs to grasp one by one again
Excessively cumbersome problem is operated caused by making, substantially increases user's interaction friendly of software.
