Step S11: the mode of operation of determining each described second functional module that current test assignment is used.
In current test assignment, the mode of operation of each second functional module can be set arbitrarily.The mode of operation that sets each second functional module is namely determined the mode of operation of each second functional module that current test assignment is used.
In the present embodiment, the mode of operation of second functional module has three kinds, is respectively mode standard, disable mode and from development mode.Under mode standard, the code of each described second functional module correspondence is standard code, and the fieldbus function of each described second functional module correspondence is standard fieldbus function.Under disable mode, the code of each described second functional module correspondence is empty.Under development mode, the code that the code of each described second functional module correspondence is write again for the initialization function that provides by described programmable software code storehouse and interface function.
Step S12: according to the mode of operation of each described second functional module, from described programmable software code storehouse, obtain the code of each described second functional module correspondence respectively.
In the present embodiment, can be according to the mode of operation of each second functional module, by manually from the programmable software code storehouse, obtaining the code of each second functional module correspondence.After the mode of operation of determining each second functional module, from the programmable software code storehouse, obtained the code of each second functional module correspondence by experimenter's manual operation.
Mode of operation with certain second functional module is mode standard, if be the code that the second functional module correspondence is manually obtained in the example explanation by the code that manually from the programmable code storehouse, obtains this second functional module correspondence, from the programmable software code storehouse, copy the code of this second functional module correspondence or be used for calling the file destination of the code of this second functional module correspondence by the experimenter, and the file destination that the code of this second functional module correspondence that will copy or be used for calls the code of this second functional module correspondence affixes to the engineering compiling window.
When the mode of operation of this second functional module changes to disable mode by mode standard, in the engineering compiling window, get final product with the code of this second functional module correspondence or for the manual deletion of the file destination of the code that calls this second functional module correspondence.
When the mode of operation of this second functional module changes to from development mode by mode standard, in the engineering compiling window, manually delete with the code of this second functional module correspondence or for the file destination of the code that calls this second functional module correspondence, then with this second functional module at code corresponding under development mode or be used for calling this second functional module and be copied to the engineering compiling window at the file destination of code corresponding under development mode, the code write again for the initialization function that provides by the programmable software code storehouse and interface function at code corresponding under development mode of this second functional module wherein.
In the present embodiment, can also from the programmable software code storehouse, obtain the code of each second functional module correspondence by compiler toggle according to the mode of operation of each second functional module.After the mode of operation of determining each second functional module, from the programmable software code storehouse, obtained the code of each second functional module correspondence automatically by compiler toggle by the experimental calculation machine.
In the present embodiment, compiler toggle is a variable, when the mode of operation of certain second functional module is mode standard, compiler toggle can be set to 0, after compiler toggle is set to 0, the experimental calculation chance is obtained the code of this second functional module correspondence under mode standard automatically from the programmable software code storehouse, insert the engineering compiling window.
When the mode of operation of certain second functional module is disable mode, compiler toggle can be set to 1, after compiler toggle is set to 1, the experimental calculation machine obtains the code of this second functional module correspondence under disable mode from the programmable software code storehouse, insert the engineering compiling window, wherein this second functional module corresponding code under disable mode is empty.
When the mode of operation of certain second functional module is during from development mode, compiler toggle can be set to 2, after compiler toggle is set to 2, the experimental calculation machine obtains this second functional module at code corresponding under development mode from the programmable software code storehouse, insert the engineering compiling window, wherein the code write again for the initialization function that provides by the programmable software code storehouse and interface function at code corresponding under development mode of this second functional module.
Step S13: according to the linking relationship of each described second functional module, the code of each described second functional module correspondence is carried out compiling link, generate second executable file.
In the present embodiment, chained file in the programmable software code storehouse records the linking relationship of each second functional module, and chained file is the code in the programmable software code storehouse, according to chained file the code of each second functional module correspondence is carried out compiling link then, generate second executable file at last.
Step S14: described second executable file of burning is to described experimental terminal, to carry out the fieldbus functional test.
In the present embodiment, the experimental calculation machine is burned onto experimental terminal with second executable file, experimental terminal is downloaded described second executable file, and move described second executable file, when experimental terminal brings into operation second executable file, standard terminal first executable file that brings into operation is to carry out the fieldbus functional test.First feedback information that the standard terminal will produce in the time of will moving first executable file is sent to the experimental calculation machine, and second feedback information that experimental terminal will produce in the time of will moving second executable file is sent to the experimental calculation machine.
Step S15: first feedback information when described first executable file is moved in second feedback information when receiving described experimental terminal and moving described second executable file and described standard terminal, and with described second feedback information and described first feedback information as the fieldbus functional test results.
In the present embodiment, first feedback information when described first executable file is moved in second feedback information when being received described experimental terminal and moved described second executable file by the experimental calculation machine and described standard terminal, and with described second feedback information and described first feedback information as the fieldbus functional test results.
In the present embodiment, the mode of operation of each second functional module of experimental terminal is under the mode standard situation in current test assignment, can understand the standard fieldbus function of this second functional module correspondence according to the fieldbus functional test results of current test assignment.
The mode of operation of any one second functional module of experimental terminal is under the situation of disable mode in current test assignment, in the time of can understanding the fieldbus afunction of this second functional module correspondence according to the fieldbus functional test results of current test assignment to the influence of experimental terminal operation.
The mode of operation of any one second functional module of experimental terminal is under the situation of development mode in current test assignment, can judge according to the fieldbus functional test results of current test assignment whether this second functional module is identical with the fieldbus function of this second functional module correspondence under mode standard in fieldbus function corresponding under development mode, if this second functional module is identical with the fieldbus function of this second functional module correspondence under mode standard in fieldbus function corresponding under development mode, the code of writing again that this second functional module correspondence then is described is correct, otherwise, illustrate that the code of writing again of this second functional module correspondence is incorrect.
Be this second functional module in fieldbus function corresponding under development mode and this second functional module under the identical situation of the fieldbus function of correspondence under the mode standard in judged result, can also be according to this second functional module in the fieldbus functional test results under development mode and the fieldbus functional test results of this second functional module under mode standard, relatively whether this second functional module is better than the fieldbus performance of this second functional module correspondence under mode standard in fieldbus performance corresponding under development mode.Pass through comparative result, determining has the excellent poor reason that has in the fieldbus performance of this second functional module correspondence under development mode and under mode standard, by the fieldbus performance of analyzing in this second functional module correspondence under development mode and under mode standard the excellent poor reason that has is arranged, further understand the method for operation of fieldbus and the working mechanism of fieldbus.
Wherein, according to the fieldbus functional test results of current test assignment judge this second functional module fieldbus function corresponding under development mode and this second functional module under mode standard corresponding fieldbus function whether identical detailed process is: whether consistent to information that should second functional module in the information of the first identical functional module of this second functional module function that neutralizes owing to first feedback information in the fieldbus functional test results of this second functional module more current test assignment under mode standard and second feedback information, if unanimity as a result, illustrate that then this second functional module is identical with the fieldbus function of this second functional module correspondence under mode standard in fieldbus function corresponding under development mode, if the result is inconsistent, illustrate that then the fieldbus function of this second functional module correspondence under mode standard in fieldbus function corresponding under development mode and this second functional module is inequality.
In the process of the code of writing this second functional module correspondence again, the experimenter can be familiar with the exploitation of embedded system, the device level programming of communication protocol stack.
In current test assignment, the mode of operation of second functional module of any one in the experimental terminal can not be set to simultaneously mode standard, disable mode and from development mode, but the mode of operation of any one second functional module can have nothing in common with each other in different test assignments.When the mode of operation of any one second functional module has nothing in common with each other in different test assignments, the fieldbus functional test results of each test assignment correspondence has nothing in common with each other, and the test result that has nothing in common with each other according to each test assignment can be understood the method for operation and the working mechanism of the fieldbus function of this second functional module correspondence.Because the mode of operation of any one second functional module can have nothing in common with each other in the experimental terminal, therefore can recognize the method for operation and the working mechanism of the fieldbus function of each second functional module correspondence in different test assignments.
In this application, each first functional module in second functional module of each in the experimental terminal and the standard terminal is by obtaining the division of field bus device implementation structure level.Certainly, each first functional module in second functional module of each in the experimental terminal and the standard terminal also can be obtained by other dividing mode.
Wherein, each second functional module can be respectively in the experimental terminal: transmitting-receiving driver module, clock synchronization module, communication scheduling module, process binding module, system service module, information management module, file system module.
Wherein, described transmitting-receiving driver module is used for driving the physics R-T unit;
Described clock synchronization module is used for adjusting described experimental terminal and described standard terminal system clock, makes described experimental terminal and described standard terminal keep system clock synchronous;
Described communication dispatch module is used for planning fieldbus medium and utilizes mode, so that fieldbus reaches industry determinacy requirement in real time; Wherein, planning fieldbus medium utilizes mode to refer to plan when the field bus device node sends data, when take the fieldbus data medium and how long take the fieldbus data medium.It is to clash when avoiding each field bus device node to send data that planning fieldbus medium utilizes the purpose of mode.
Described process binding module is used for the described experimental terminal of binding and described experimental terminal client layer program, to finish communication function;
Described system service module is used for providing the application layer entity access services to described experimental terminal;
Described information management module is used for the attribute of the described experimental terminal of management and described experimental terminal to the operation of described fieldbus experiment porch;
Described file system module, the data that produce during for the configuration file of managing described experimental terminal and described experimental terminal operation executable file.
Each of standard terminal first functional module can be the first transmitting-receiving driver module identical with transmitting-receiving driver module function, first clock synchronization module identical with the clock synchronization module function, the first communication scheduling module identical with the communication scheduling functions of modules, the first process binding module identical with process binding module function, the first system service module identical with the system service functions of modules, the first information administration module identical with the information management module function, first file system module identical with the file system module function.
Be that example is elaborated to the method for operation and the working mechanism that can understand the fieldbus function according to the fieldbus functional test results with clock synchronization module in the experimental terminal in the present embodiment now.Wherein, the module identical with clock synchronization module function in the experimental terminal is first clock synchronization module in the standard terminal.
When the clock synchronization module when the mode of operation in the first time test assignment is mode standard, the primary scene bus functionality test result of test assignment can be understood the standard fieldbus function of clock synchronization module correspondence according to the first time.
When the clock synchronization module when the mode of operation in the second time test assignment is disable mode, according to the second time test assignment secondary scene bus test result can understand the fieldbus afunction of clock synchronization module correspondence the time to the influence of experimental terminal operation, thereby understand the necessity that the fieldbus function of clock synchronization module correspondence exists.
When the clock synchronization module is during from development mode in the mode of operation in the test assignment for the third time, the code that the code of clock synchronization module correspondence is write again for the initialization function that provides by the programmable software code storehouse and interface function, can judge according to the fieldbus functional test results of current test assignment whether clock synchronization module is identical with the fieldbus function of clock synchronization module correspondence under mode standard in fieldbus function corresponding under development mode, if clock synchronization module is identical with the fieldbus function of clock synchronization module correspondence under mode standard in fieldbus function corresponding under development mode, the code of writing again that the clock synchronization module correspondence then is described is correct, otherwise, illustrate that the code of writing again of clock synchronization module correspondence is incorrect.
Be this clock synchronization module at fieldbus function corresponding under development mode and this clock synchronization module under the identical situation of the fieldbus function of correspondence under the mode standard in judged result, can also be according to this clock synchronization module in the fieldbus functional test results under development mode and the fieldbus functional test results of this clock synchronization module under mode standard, relatively whether this clock synchronization module is better than the fieldbus performance of this clock synchronization module correspondence under mode standard in fieldbus performance corresponding under development mode.Pass through comparative result, determining has the excellent poor reason that has in the fieldbus performance of this clock synchronization module correspondence under development mode and under mode standard, by the fieldbus performance of analyzing in this clock synchronization module correspondence under development mode and under mode standard the excellent poor reason that has is arranged, further understand the method for operation of fieldbus and the working mechanism of fieldbus.
Wherein, because the fieldbus function of the fieldbus function of the first clock synchronization module correspondence of standard terminal and the clock synchronization module of experimental terminal correspondence under mode standard is identical, therefore in current test assignment, judge clock synchronization module when whether identical whether with clock synchronization module corresponding fieldbus function under mode standard fieldbus function corresponding under development mode, only need judge that clock synchronization module is the fieldbus function of the first clock synchronization module correspondence of the fieldbus function of correspondence under development mode and standard terminal identical getting final product whether according to the fieldbus functional test results of current test assignment.
By the comparison clock synchronization module in first time test assignment corresponding standard fieldbus function and clock synchronization module in the second time test assignment during corresponding fieldbus afunction to the influence of fieldbus experiment porch operation, understand the effect of the fieldbus function of clock synchronization module correspondence.
By the comparison clock synchronization module in first test assignment corresponding fieldbus function, in second test assignment during corresponding fieldbus afunction to the influence of fieldbus experiment porch operation and the corresponding code that passes through to write is again realized in the 3rd test assignment fieldbus function, can understand the method for operation and the working mechanism of the fieldbus function of clock synchronization module correspondence.
The fieldbus functional test results is the test result of current test assignment, and after test assignment changed, the fieldbus functional test results can change with the change of test assignment.
In this application, experimental terminal comprises a plurality of second functional modules, and the function that each second functional module has is corresponding one by one with each function of fieldbus, therefore understand each function that to understand fieldbus by each second functional module to experimental terminal, and then draw the inner structure of fieldbus by each function distribution of fieldbus.
In this application, the mode of operation of each second functional module is corresponding with test assignment in the experimental terminal, therefore in different test assignments, each second functional module can conversion mode of operation separately, and second executable file is to generate according to the mode of operation of each second functional module, therefore second executable file of different test assignment correspondences has nothing in common with each other because of the change of the mode of operation of second functional module, feedback information when having nothing in common with each other operation second executable file of different test assignment correspondences as can be known by second executable file of different test assignment correspondences has nothing in common with each other, feedback information during by operation first executable file of the identical different test assignment correspondences as can be known of first executable file of different test assignment correspondences is identical, and then the feedback information during by operation second executable file of different test assignment correspondences has nothing in common with each other, and the identical fieldbus functional test results of different test assignment correspondences as can be known of feedback information during operation first executable file of different test assignment correspondences has nothing in common with each other.Can understand the method for operation of fieldbus and the working mechanism of fieldbus by the fieldbus functional test results that contrasts different test assignment correspondences.
When carrying out the fieldbus functional test, do not limit the number of experimental terminal in the experiment porch, when having only an experimental terminal in the experiment porch, need to understand the method for operation of fieldbus and the working mechanism of fieldbus by the fieldbus functional test results of the different test assignment correspondences of contrast.
In experiment porch, comprise a plurality of experimental terminal, and when the functional module that each experimental terminal comprises is identical, can be in test assignment, the mode of operation of each experimental terminal identical functions module is had nothing in common with each other, under the situation that the mode of operation of each experimental terminal identical functions module has nothing in common with each other, second executable file that each experimental terminal obtains has nothing in common with each other, because each self-corresponding second executable file of each experimental terminal has nothing in common with each other, feedback information when each experimental terminal is moved each self-corresponding second executable file has nothing in common with each other, feedback information when first executable file is moved in the feedback information when moving each self-corresponding second executable file according to each experimental terminal and standard terminal can be understood the method for operation of fieldbus and the working mechanism of fieldbus.
When comprising an experimental terminal in the experiment porch, need to understand the method for operation of fieldbus and the working mechanism of fieldbus by the fieldbus functional test results of the different test assignment correspondences of contrast, owing to repeatedly test, so inefficiency, but owing to only need an experimental terminal, therefore the cost of test is low; When comprising a plurality of experimental terminal in the experiment porch, owing to can understand the method for operation of fieldbus and the working mechanism of fieldbus by once testing, so high efficiency, but owing to need a plurality of experimental terminal, testing cost height.Certainly in actual applications, can select corresponding experiment porch to carry out the fieldbus functional test according to actual conditions.But no matter the number of the experimental terminal in the experiment porch is several, and the method for carrying out on-the-spot functional test is constant, a kind of method of testing based on the fieldbus experiment porch as shown in Figure 1.
When carrying out the fieldbus functional test, do not limit the number of standard terminal in the experiment porch yet, but more accurate for the fieldbus functional test results that guarantees to be obtained by the fieldbus experiment porch, at least two standard terminals can be set.Arrange at least two standard terminals can make the fieldbus functional test results more accurately former because: if the standard terminal of fieldbus experiment porch has two, be respectively standard terminal A and standard terminal B, when standard terminal A or standard terminal B break down, the feedback information of standard terminal A is different with the feedback information of standard terminal B, one of them fault occurred among standard terminal A and the standard terminal B as can be known by different feedback informations, after one of them breaks down in discovery, fault is got rid of, after fault is got rid of, proceeded experiment again.If the standard terminal has only one in the fieldbus experiment porch, when break down in the standard terminal, the feedback information that obtains is wrong and can not find that the feedback information that obtains is that standard terminal by fault obtains, and causes experimental result inaccurate.
As shown in the above, the fieldbus experiment porch has two standard terminals than the fieldbus experiment porch standard terminal to be arranged, and the fieldbus functional test results that obtains is more accurate.When the standard terminal of fieldbus experiment porch during more than two, the fieldbus functional test results that the fieldbus functional test results that obtains obtains when the standard terminal of fieldbus experiment porch is two is more accurate.
