Description
Technical field
The present invention relates to computer application field, particularly a kind of signal generator data interactive method based on VxWorks.
Background technology
In today of computer technology and rapid development of information technology, vxworks operating system is widely used in the field such as industry, military affairs, as military and national defense, Industry Control, traffic administration, home intelligent management, ecommerce etc. with its good reliability and remarkable real-time.
Just because of VxWorks embedded OS a large amount of be applied in every field, therefore to using the work of this embedded OS software maintenance also day by day to increase, such as software upgrading has function with the defect and program error, improvement that correct design or increases new function etc.Therefore how the convenient instrument with having vxworks operating system carries out data interaction, becomes the link that modern intelligent instrument Software for Design is paid close attention to gradually.
At present, existing with use the signal generator of VxWorks to carry out data interaction have two kinds of modes: a kind of method is that instrument maintenance personnel stop instrument running to instrument at the scene, then machine of tearing open changes instrument CF card, FLASH supervisor memory device, or use instrument to reform vxworks operating system at the scene, for the target machine not having network interface, this is unique operable data interactive mode.
The condition precedent that another kind method is carried out is that signal generator itself has network interface, software development due to VxWorks completes on host, carry out after having developed compiling, link and obtain system map file, re-using cross integration development environment (Tornado) utilizes network and target machine to establish the link, then by network, system map file is downloaded in target instrument, complete the work of data interaction.
Instrument maintenance personnel are carried out to the method for data interaction to instrument scene, major defect is:
(1) in data exchange process, target instrument cannot use, if target instrument number is many, distribution far away, this mode wastes time and energy especially, with high costs.
(2) because needs change instrument CF card or FLASH memory, this, with regard to needing machine of tearing open the work carrying out signal generator at user scene, may have an impact to the inside sensitive circuit of signal generator, and then affect the performance index of instrument.
For use cross integration development environment method, major defect is:
(1) need the computing machine mutual with target instrument that cross integration development environment (TORNADO) is installed, and this development environment is payware, expensive.
(2) need operating personnel to adopt the mode of designator, the data needing to write or write out are sent in target instrument, the ability of maintainer be there are certain requirements.
(3) data adopting this kind of method mutual lack checking procedure, if gone wrong in the process data write out, target instrument can be caused to occur the situation that cannot start or instrument software is made mistakes.
Summary of the invention
For the signal generator solving above-mentioned use VxWorks carries out data interaction Problems existing, the invention provides a kind of signal generator data interactive method based on VxWorks.
Technical scheme of the present invention is achieved in that
Based on a signal generator data interactive method for VxWorks, comprise the following steps:
Step (a), creates a data interactive window;
Step (b), utilizes the verification menu in above-mentioned data interaction window to add check code for file destination;
Step (c), select target file;
Step (d), according to the communication interface that the signal generator of user's use provides, any one in choice for use network, GPIB or RS232 communication interface completes data interaction;
Step (e), batch imports/derives file destination.
Alternatively, in described step (a), the class utilizing Microsoft Foundation class libraries to provide generates data interaction window, adds corresponding control according to current needs; Then CFileDialog class is utilized to create file selection box general in Windows system.
Alternatively, in described step (a), adding control has progress bar control, list box control.
Alternatively, in described step (b), when sending data file to target instrument, the verification menu in click data interactive window, in response BN_CLICKED Message function, utilize file manipulation function this file before, middle, the check code that finally adds 32 bytes, after target instrument receives this check code, compare, if check code is identical, then will be transferred to the file access pattern of target instrument, and final alternative target instrument file.
Alternatively, in the process of described step (e) batch importing/export, after each file transfer completes, then pass through file manipulation function, open file, and the check code that diverse location reading is added from file carries out file verification, if find, check code is different, then point out this document transmission process to make mistakes, and transfer instruction is again sent to transmission side, if still bust this, then stop this transmission, the remaining file of listed files also no longer transmits.
The invention has the beneficial effects as follows:
(1) interface that user's cognition degree is very high is provided;
(2) interface needs to provide connected mode that is multiple and instrument communication according to user, and information displaying enriches, prominent function;
(3) user can also carry out handled easily to the various parameters of target instrument needed for oneself, and requires according to user the ability generating various file.
