Problems solved by technology
[0003] However, the embedded numerical control system is different from the numerical control system based on the PC platform. Its hardware resources are limited, and performance monitoring cannot occupy too many system resources.
Therefore, only a simple way of printing out to the screen for observation or recording to a file for post-analysis can be used instead of graphical monitoring
This is not intuitive and convenient, nor can it be tracked in real time

Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] figure 1 It is a system structure diagram of the remote performance monitoring of the embedded numerical control system applied in the present invention.
[0034] In order to better understand the method of the present invention, each module and task in the system are now described one by one:
[0035] (1) Shared memory module
[0036] In the method of the invention, all performance data are stored in a shared memory, which facilitates data management and transmission.
[0037] Divide the shared memory into partitions, each partition corresponds to an acquisition module, and each acquisition module can only store the data it collects in its corresponding partition.
[0038] In order to meet the different requirements of the storage space required by different acquisition modules and avoid the waste of shared memory, the memory partit...

The invention relates to the technical field of numerical control, in particular to a method for monitoring the performance of an embedded type numerical control system. According to the embedded type numerical control system, a corresponding memory sharing zone is appointed to each collecting module by a memory zone management module; collected performance index data are stored in the corresponding memory sharing zone through the collecting module; the performance index data in each memory sharing zone are transmitted to a remote monitoring system by a transmission module through the Ethernet; according to the remote monitoring system, the transmitted performance index data are received by a data extracting module and stored in a corresponding data file and imaging display is conducted on the performance index data through an image displaying module. The method for monitoring the performance of the embedded type numerical control system is good in instantaneity, high in speed of data transmission, reliable in data transmission, visual and graphic in expression and capable of enabling a new performance monitoring task to be extended easily and enabling each performance data collecting module to be independent and free of interference.
Description
technical field [0001] The invention relates to the technical field of numerical control, in particular to a method for performance monitoring of an embedded numerical control system. Background technique [0002] At present, some domestic numerical control systems (especially high-performance numerical control systems) are still in the stage of technological exploration, and the monitoring of various static and dynamic performances of numerical control systems is helpful to the design, testing, and operation of numerical control systems. Developers or maintenance personnel hope to obtain parameters that reflect system performance as soon as possible, so that they can more reasonably select components used in the system, evaluate system design schemes, find out performance bottlenecks in the system, and optimize the design. Lay the foundation for development. [0003] However, the embedded numerical control system is different from the numerical control system based on the ...
