Description of the drawings
Fig. 1 is the connection block diagram of present system.
Specific embodiment
With reference to the accompanying drawings and examples the invention will be further described.
The embodiment of the present invention and its implementation process are as follows：
In a preferred embodiment of the present invention, the electric energy storage device test system is flat using Matlab/simulink
Platform, compatible favorable expandability can be promoted relatively broadly, be capable of achieving prolonged Based Intelligent Control, be realized high-precision automatic
Change.
Situation is precisely obtained in real time by smart power instrument in embodiment, and adds data database storing, will be gathered
Data storage and be analyzed.
The first step：Solve the connection of host computer and equipment and communicate.
With No. ID and the path parameter that equipment communication needs equipment, parameter can obtain in tmtool to particular device
Take.Meanwhile, carry systematic function using tmtool in matlab and communicated with equipment, but the communication is for user
Still too coarse, needs proceed to encapsulate and optimize.
First, the connection of equipment needs the operation that communicated, and the species for communicating mainly has two kinds, be respectively write with
Inquiry.Write mould and correspondence encapsulation function is write respectively using above two communication mode.
Secondly, in connection after equipment, need to carry out equipment frequent read and write access operation, while the connection to equipment is entered
The rational preservation of row carrys out guaranteed efficiency.
In this step, the communication of host computer and equipment is realized, and encapsulation makes its easy-to-use.
Second step：Realize the order described in device's document.
By the information needed for the confluence analysis to instructing simultaneously comprehensive each step, having extracted 5 kinds instructed per bar can match somebody with somebody
Confidence ceases：
1. whether initialization sends information
Whether expression needs to send commands to equipment when program brings into operation.Mainly pass through in code
Access arrays are controlled.
Realization approach is：Using persistent keywords in Matlab, make every time same into using during function
Access arrays, the value of access correspondence positions can add one when certain instruction is accessed every time, represent this instruction at this
System is accessed several times during starting.And in follow-up code, whether the value by decision instruction correspondence access is big
Real execute instruction is chosen whether in 0.
Initial access is 0 when initialized, and execute instruction is not needed when representing and access for the first time, 0 value
Initialization corresponds mainly to that the input type of callback can be called when program starts and performs.Will be detailed in 3rd step
Describe this attribute.
2. inquire about or writing commands
Whether the method for operating in correspondence communication module, concrete value needs return value relevant with the instruction.By array
Method is configured, and 1 represents inquiry, and 0 represents write.
3. additional parameter number
Represent whether the order has extra alternative parameter.Configured by value arrays, program is in operation
During the value of composition instruction is obtained by the respective value in value arrays.
4. instruction is called
For representing the brief name of certain instruction.Configured using param arrays.
This name is unique in whole program, is the proof of identification of instruction.External function by the name call this
Instruction in group.Meanwhile, the mask variable names that this instruction is also ensure that in the mask encapsulation of the 3rd step are also this
Another name, is easy to the acquisition of user input.
5. instruction format
Instruction format represents the form of certain instruction, i.e., how to be spliced into according to multiple required user input values and be sent to
The instruction of equipment.The instruction has substantial connection with the 3rd parameter, is mainly configured by command arrays.
After configuration code terminates, instruction execution flow is entered into.Execution sequence is to find out correspondence according to instruction another name
All configurations, and according to configuration parameter, order parameter and instruction format are read, after generating actual instruction, according to previous
Step provides method and apparatus and is communicated, and reaches the purpose of control device.
The step is truly realized control of the user to slave computer.
3rd step：
At this time, it may be necessary to some optimizations can be carried out to the instruction execution mode in previous step, graphic interface is used
Sub-system and mask encapsulation in simulink.
In mask encapsulation, what is mainly deposited is the instruction of once-type.
The characteristics of this instruction is that call number is few, meanwhile, in most of the cases need to add some parameters manually.
And mask encapsulation disclosure satisfy that this requirement just.Mask encapsulation graphical interfaces in have conventional drop-down menu, input frame with
And button.In the case where the input of multiple types is supported, writing commands can be very good encapsulation, and user requires no knowledge about the order of each
It is how to be sent to equipment, it is only necessary to very easily used by the meaning for knowing each input item.
A callback function in being simulink under the top layer that user uses.Callback is mask configurations
One.In each project after value changes, the small routine section write on inside callback can be actively called by system.
So, it is only necessary to the order line statement write out in the sentence i.e. second step that triggering transmission corresponding instruction is write in callback is i.e.
Can.
And when mask runs for the first time, in addition to type of button, remaining input type can be called once
The callback for setting.For the correctness for arranging, the readjustment of this initialization type can be manually forbidden in code.This is
Be access attributes be 0 the reason for.Certainly, as button etc never call when initialized call back function in configuration
When only need to normally be used by access attributes are put into 1.
Considerations above it is most be instruction write, and least a portion of instruction is with return value.For Consumer's Experience,
Return value can not be exported in order line.So, there is a FX for setting in advance on interface, each return value is all
Can be write direct that block region, facilitate user to check return value.
Here, by taking the inputState orders for above occurring as an example, illustrating how to carry out mask encapsulation.Firstly, since
The order is a write instruction, at the same need an opening input, so using editor as the instruction input
Frame, receives input.And if limited input, it is possible to use popup is that drop-down list type is controlled.And if be not required to
It is input into, then the use of button is directly type of button.
And in the attribute of the editor, variable name is set to another name inputState and facilitates journey by needs in mask configurations
Sequence is obtained.Meanwhile, as described above, in callback hurdles, needs actively call the trigger command of respective modules with logical
Know that program obtains newest value and is sent to equipment.
In Sub-system encapsulation, what is mainly deposited is the instruction of inquiry type.The instruction calls often, but every time
The parameter called is basically identical.Therefore, it is similar to step 2, need the inquiry first by query function to equipment to be packaged.
Then, query function is packaged using subsystem, to last Query Result is externally provided, middle all operations are used
It is negligible per family.
Simultaneously Sub-system is the meaning of subsystem encapsulation and is incessantly this.Its major function is that user is encapsulated
Concrete implementation details and only reserved port.Under this packaged type, the readable and reliability of module is substantially increased.
In subsystem encapsulation, in order to interact with the external world, need to specify several in ports and out ports.And the number of each port
Input or need externally exposed output that amount is relied on depending on the module.
In addition, after Sub-system is encapsulated, Simulink can be added it to by some modes
Subsequently used with facilitating in Library Brower.Specific mode connects referring to the end of writing, repeats no more in text.In this, the son
System is not merely an application, but a kind of module in Simulink.When there is user to need to use the subsystem,
Only need to find and use by being configured.Modularity is greatly enhanced.
For the Sub-system encapsulation of high accuracy analysis instrument, it is desirable to provide four outputs, its equipment is represented respectively
The voltage of reading, electric current, performance number and Matlab are by calculated performance number, it is not necessary to be input into.
For voltage, the function for separately writing a read voltage is needed to exclusively carry out reading.Meanwhile, need a square wave to occur
The operation of device clocked flip function reading.An output point is also needed to as the output of function.Now, the magnitude of voltage can be with
Acquired in outside.
