The characteristics of each equipment is directed to when quasi- data equipment, selecting follow-up test needs equipment variables to be used, such as ammeter
Performance number develops corresponding assignment script for each variable, and name variable, assignment script check mark is stored in Object Notation
In table, in subsequent test process, both system testing can be carried out according to default script when developing, it can also be by testing
Personnel modify assignment script and are oriented test, and the test flexibility of the method for the present invention is higher, and because being full software design,
It is not take up space, is not related to material object, testing cost is smaller.The method of the present invention passes through multithreading equipment simulating algorithm for virtual data
Equipment is divided into multiple threads, it is ensured that the resource component of per thread utilizes, and avoids network resources waste, has further reduced test
Cost.
Detailed description of the invention
Fig. 1 is a kind of step flow chart of the full soft data equipment simulating method of PaaSization of the present invention.
Specific embodiment
Technical solution of the present invention is described further with reference to the accompanying drawing:
A kind of full soft data equipment simulating method of PaaSization, as shown in Figure 1, comprising the following steps:
S1, analysis mode demand calculate virtual data number of devices, and determine the corresponding variable of each equipment, variable herein
Refer in the virtual unit can assignment parameter.For example power plant's simulation system, the virtual data equipment needed have generator, pot
Furnace, ammeter etc., variable in need of consideration has rate, period, power, ammeter value etc. in ammeter.
S2, virtual data equipment is constructed using python language, it is virtual that developer writes code building on the server
Data equipment, to data equipment variable assign value interval, and according to normal operating conditions set a default value patrol
Volume, while one end assignment script is write, allow to carry out variable assignments by assignment script.
S3, the simulation plug-in unit generating device example in cloud client call S2 compiled virtual unit, and according to equipment
Corresponding variable establishes Object Notation table, and concrete operations are as follows:
S31, virtual unit is called to simulate plug-in unit generating device example, for example, calling the script of the ammeter of S2 compiling in computer
One simulation ammeter of upper generation.
S32, device instance and the corresponding variable of device instance are numbered, device instance and the corresponding change of device instance
The number of amount be it is the same, generally there are multiple identical virtual units in a test macro, all virtual units and
Its corresponding variable should have unique number.
S33, the assignment script of device numbering, equipment variables title and equipment variables is sequentially stored in Object Notation table
In.
S4, virtual data equipment is divided into multiple threads using multithreading equipment simulating algorithm, concrete operations are as follows:
The ratio value of interaction time-out, test during the time delay value of duration, interaction permission that S41, setting single thread are tested and test
Number of the interaction time delay more than the permissible delay value of setting and total interaction times during the ratio value of period interaction time-out is test
Ratio.
S42, virtual unit quantity is continuously increased in single thread, test meets the single thread of interaction time delay requirement
Maximum holds carrying capacity.
S43, all virtual data equipment is divided by multiple threads according to single thread maximum appearance carrying capacity.
S5, virtual data equipment composition virtual test system is connected with proxy for equipment using virtual communication link.It is virtual logical
Letter link is the functional module for connecting the virtual data equipment of any required communication with one another, both can connect same
Virtual unit in a thread can also connect virtual unit with cross-thread.Proxy for equipment will be for that will need to connect hardware serial ports
Virtual unit is connected on nearest serial ports, when some virtual unit connects hardware serial ports by proxy for equipment, in the computer
The upper serial ports, which can be shown, have been occupied, meanwhile, in the same thread, it is only necessary to which one of them proxied equipment opens physics string
Mouth can represent the equipment of all chain roads, and all serial ports is online.
In order to preferably resource be utilized to connect conducive to the horizontal extension of the resource in from cpu to process of server resource
Multi-process+multithread mode is used during virtual unit, centre is coordinated between multi-process+multithreading by flexible bus mode
Resource coordination.
S6, the variable for carrying out virtual test according to default logic or modifying virtual unit in Object Notation table carry out empty
Quasi- test, specific operation are as follows:
S61, the default script in virtual unit simulation plug-in unit is called to carry out virtual test, such as ammeter equipment, when calling exploitation
The logic in default script write, ammeter power changes according to sequence from low to high in the valued space of permission, generates
The ammeter power test data of default.
S62, by uniquely numbering or name variable is searched in Object Notation table and needs the equipment of fc-specific test FC.
S63, tester can give variable random assignment in Object Notation table using the assignment script of equipment variables.
S64, operation assignment script, change the variable of the virtual unit, generate specific equipment test data.
S7, the resident layer of data is transmitted test data to, and is successively saved in Redis database from resident layer, it is specific to grasp
Make as follows:
S71, data established in cloud client be resident layer, data, which are resident layer, has a fixed memory, data be resident in layer setting with
The number of threads of test macro is identical and sequentially connected storage queue, and the data resident time is arranged.
The test data that equipment generates in S72, some thread is stored in data by connected storage queue and is resident layer.
S73, data are successively resident the storage of the data in layer to Redis database sequentially in time；For liveness
Higher thread or equipment preferentially can be put in storage and be stored.
S74, in order to prevent loss of data, data will not be resident layer deletion from data at once after being stored in Redis database,
Data through being put in storage can be confirmed whether to be stored in Redis database after reaching data residence time, be not stored at once into
Row storage, only reaches data residence time and the data for being stored in Redis database just will do it cleaning.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the invention is not limited to above-mentioned
Embodiment within the knowledge of a person skilled in the art can also be before not departing from present inventive concept
It puts and makes a variety of changes.
