Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Flow chart when Fig. 1 is present system verifying.
Specific embodiment
The principle and embodiment that the invention will now be described in detail with reference to the accompanying drawings.
As shown in Figure 1, intelligent test system of the invention mainly includes simulation model, input data executive device and tests
Demonstrate,prove module.Below by taking testing air conditioner as an example, each section to be described in detail.
Simulation model is built according to the function logic function book of product to be measured, the test case write according to user
Importation carry out the calculating logic of automatic running test case, then obtain operation result.Wherein, the input unit of test case
Divide and specifically includes input parameter, the value of input parameter, the order for inputting parameter and duration.
Any function point of air-conditioner set is all made of input Parameter Conditions, calculating logic, timing, output result etc..
For example, often there is XX condition (input Parameter Conditions) to continue 3 minutes in function logic book, then YY condition continues 1 minute etc. again,
Then an output result is obtained.Corresponding, the prior art then needs to have input in the test case for writing the function point
Parameter, duration, order, calculating logic, output these elements of result.And the present invention is when write test case, only
It needs to consider to cover function point to be measured, parameter and its numerical value will be inputted in order and the duration is write out, i.e., manually
Write the importation for only needing to be performed test case.This is the first step of process, such as, function point is when continuous 3
Minute environment temperature is greater than 30, A valve and opens, and it is 30 and some special that the test case that we write, which just surrounds environment temperature,
Value, such as first environment temperature=29, continue 3 minutes, Article 2 environment temperature=30, continue 3 minutes ... and so on.And it is right
In the result drawn according to these corresponding calculating logics of input Parameter Conditions without calculating.
Assuming that there is a function point to be measured in function logic book are as follows: when environment temperature be greater than 30, continue 3 minutes, A valve is opened
It opens.So we are when building simulation model, it is only necessary to prepare the importation of the test case of following table, and exporting result is not
By manual compiling, but in such a way that logical simulation models, pass through the calculating of simulation model automatic running test case
Logic obtains output result.
1 manual compiling of table inputs parameter list
The operation result that 2 simulation model automatic running of table generates
Have during writing the importation of test case, under the different operating conditions of product to be measured mutually convertible described defeated
The title for entering parameter wants identical, it is ensured that versatility of the same model under different operating conditions, meaning mentioned here are mutually all
Physical significance is identical, for example, the compressor operating frequency in some logic function books, is patrolled what another research staff was write
Compressor frequency or running frequency may be written to by collecting in function book, and such case should be unified for a title, for another example
Some outdoor environment temperatures may be written to outdoor dry bulb, the title of this same physical meaning in the logic function book of part
A title should be unified for.In the test of simple function point, the duration of importation can adopt in analogue system
Embodied with the multiple mode of fixed step size, if simulation model step size settings be 1s, then be separately operable three 10 steps of use-case, 20 steps,
10 steps.In a bit complicated function point test process, the overlong time of test case causes simulation time too long, then may be used
To be solved using the means for increasing step-length.Specifically, the test case of simulation model can be divided at least one set, one group of test
The step-length of use-case is the greatest common divisor of this group of test case all duration, and the step-length of difference group test case can not
Together, for example the duration of first test case is 15s, and the duration of Article 2 test case is 10s, Article 3 test
The duration of use-case is that 20s can be designed completely if we only consider this three test cases (assuming that they be one group)
Step-length is 5, is equivalent to 5 times of speed in this way and is calculated.When more than one set test case, this step-length can be variation
, one step-length of first three use-case, behind three can be another step-length, and so on, such variable step is calculated, can
To accelerate calculating speed, that is, it can ensure that and promote simulation velocity in error-free situation, further raising efficiency.Simulation model is realized
Calculating logic can use high-level language (such as C#) Lai Kaifa, and exploitation is according to the logic function book for being exactly the function point, emulation meter
Obtained result is handled as the output par, c of test case, and the test for collectively constituting complete set with above table is used
Example.
Input data executive device needs are built according to the system architecture of product to be measured, for by the input of test case
Part, which is input in product to be measured, to be allowed to operate normally, to obtain actual operation result.Wherein input data executes
Device includes the first execution module for simulating the communication class data for generating product to be measured, and generates production to be measured for simulating
Second execution module of the communication class data of product.
Continue by taking air-conditioning as an example, in the input data executive device for building air-conditioning, need to refer to unit is the present invention
System topological structure, is developed for specific controller characteristic.For example a set of domestic air conditioning unit is by outdoor unit, indoor unit and distant
Control device composition.The input network of this set system has communication network interior, between outdoor unit, the communication between remote controler and indoor unit
Network, remote controler internal key operation display communication network etc..Therefore it needs input parameter being divided into communication class and communication class
Two kinds, communication class data are subdivided into three kinds of different communication networks, and the first execution module is by respective protocol translation at communication
Data input in indoor unit, outdoor unit and the controller of remote controler three.Communication class data refer mainly to simulation class data
(such as temperature sensing package sampled temperature data etc.), relay class data (open and close).This kind of data need to develop independent work
Loading board makes the second execution module, using the means of digital simulation AD value and switching value, and designs a set of agreement as data
Transmission.We press this agreement, and communication class data are input to input data executive device, and then input data executive device has
There is the interface that can be connected into unit, instead of true unit temperature sensing package and switching load.One may finally be reached to use test
Example importation is transmitted to the effect of unit.
When verifying air-conditioner set, it is only necessary to run simulation model and make product to be measured by input data executive device
Then then operation can be obtained by test result by operation result of the authentication module to both this, complete automatic test.
If there is same a function logic, but it is applied under different unit or working condition, test is used at this time
The importation of example is different.It only needs to reformulate importation (such as above-mentioned input parameter list), continues to use
Ready-made simulation model can calculate result.Input data executive device can continue to using.In new input parameter list
Mutually convertible parameter name want identical, as long as meeting this principle, though input parameter list in input parameter order not
Together, mapping algorithm is carried out, the calculating logic mutually mapped with importation can be thus re-used, it can accomplishes to emulate
The reuse of model.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
