Description
Technical field
The present invention relates to the cure applications implementation method of storage chip RAM Software Anti-interference in the circuit such as a kind of embedded system.
Background technology
In the circuit such as embedded system, there is the exchange of the most real-time data between microprocessor and Peripheral storage chip RAM, can the quality of working environment directly affects microprocessor normally, work reliably.When especially the circuit such as AC servo driver embedded system is in strong electromagnetic naval vessel working environment, the impacts such as the instantaneous power-down come in more susceptible to spatial interference, power supply power-fail and peripheral electrical network crosstalk and transient pulse interference, often cause the misoperation of microprocessor.Solution generally uses the technology such as low pass filter, isolating transformer, Phototube Coupling, for matured product, it is necessary to re-start hardware designs and cost is high.By storage chip RAM software solidification application technology, can be on the basis of need not changing products-hardware design, it is ensured that the correctness of driver cure parameter, it is effectively improved embedded system interference free performance, enhances the reliability worked under strong electromagnetic ships environment.
Summary of the invention
It is an object of the invention to be effectively improved instantaneous power-down and the interference free performance of transient pulse interference that spatial interference, power supply power-fail and peripheral electrical network crosstalk are come in by the circuit such as embedded system, enhance the reliability worked under strong electromagnetic ships environment.
Realize the object of the invention technical solution by: first according to the environment applied, the parameter within storage chip RAM is classified, distinguish in normal course of operation without the parameter changed and user program statement, then the data field of the parameter read-in storage chip ROM of solidification will be needed, these parameters are downloaded to by programmed statements write user program the program area of storage chip ROM simultaneously, when circuit powers on and when n time is run user program, microcontroller is by having called writing with a brush dipped in Chinese ink of cure parameter and writing with a brush dipped in Chinese ink of a program ram district user program in n+1 RAM data district for n+1 time, guarantee to be cured the correctness of parameter and user program.
The present invention compared with prior art, is mainly characterized by:
(1) whole technical costs is low and is easily achieved.
(2) cure parameter in repeatedly RAM data district is write with a brush dipped in Chinese ink and the writing with a brush dipped in Chinese ink of a program ram district user program by repeatedly having called, it is ensured that the parameter that is cured and the correctness of user program.
(3) it is effectively improved instantaneous power-down and the interference free performance of transient pulse interference that power supply power-fail, spatial interference and peripheral electrical network crosstalk are come in by the circuit such as embedded system, enhances the reliability worked under strong electromagnetic ships environment.The invention will be further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the implementation method block diagram of a kind of storage chip RAM software solidification application.
Detailed description of the invention
The enforcement of combination technology solution is described further:
Step one; according to the working environment applied, various parameters in storage chip RAM built-in variable file are determined (comprise protected variable, be not protected variable, Default Value parameter, switching variable and user program etc.) numerical range of parameter; therefrom distinguish without the parameter changed and user program statement in normal course of operation, be to need the parameter that is cured by these without the parameter determination changed；
Step 2, compiles software document by communication composing software by the parameter determining solidification and writes data field corresponding in storage chip ROM；
Step 3, the parameter these being cured writes user program by programmed statements, downloads to program area corresponding to storage chip ROM by communication composing software；
Step 4, when circuit powers on, microcontroller by the calling to storage chip RAM data district and program area from storage chip ROM data district and program area, completes writing with a brush dipped in Chinese ink and the writing with a brush dipped in Chinese ink of program ram district user program for the first time of cure parameter in RAM data district for the first time；
Step 5, when microprocessor runs a user program, microcontroller, by calling operation user program from storage chip program ram district, completes writing with a brush dipped in Chinese ink of cure parameter in a RAM data district；
Step 6, when circuit once powers on, microcontroller all again through the calling to storage chip RAM data district and program area from storage chip ROM data district and program area, completes writing with a brush dipped in Chinese ink of cure parameter and writing with a brush dipped in Chinese ink of a program ram district user program in a RAM data district；
Step 7, whenever running a user program at microprocessor, microcontroller, by calling operation user program from storage chip program ram district, completes writing with a brush dipped in Chinese ink of cure parameter in a RAM data district.
When circuit powers on once with n user program of operation, microprocessor has called writing with a brush dipped in Chinese ink of cure parameter and writing with a brush dipped in Chinese ink of a program ram district user program in n RAM data district eventually through n+1 time, guarantee the correctness of cure parameter and user program, it is effectively improved instantaneous power-down and the interference free performance of transient pulse interference that power supply power-fail, spatial interference and peripheral electrical network crosstalk are come in by the circuit such as embedded system, enhances the reliability worked under strong electromagnetic ships environment.
