Data resource configuration management method applied to measuring instrument

Abstract

The invention provides a data resource configuration management method applied to a measuring instrument. The method comprises the steps of establishing correlation between local menu resources and data resources and between remote SCPI command resources and the data resources, data resource access authority control and data resource access interfaces; establishing direct correlation between the local menu resources and the remote SCPI command resources and the data resources, wherein a menu resource item is correlated with a data resource item at the maximum, and an SCPI command is correlated with multiple data resource items; declaring all the data resources to be privately-owned, wherein any client program cannot directly get access to the data resources; providing an access interface and a modification interface for each data resource item in the data resources, wherein the client programs can only get access to or modify the data resources through the access interfaces and the modification interfaces; reserving calling of virtual interfaces in the modification interfaces of the data resource items, wherein the client programs achieve automatic setting of correlation parameters by rewriting the virtual interfaces.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a data resource configuration management method applied to measuring instruments. Background technique [0002] In order to facilitate the construction of test systems, measuring instruments are usually required to provide two control methods, one is to directly complete the local settings of the instrument through the buttons on the front panel of the instrument, and the other is to send SCPI commands to the host through GPIB, LAN or USB communication methods. The instrument, and then the instrument parses and executes the command to complete the remote setting of the instrument. [0003] The measuring instrument only accepts one input method at any time, that is, when the instrument is set remotely, the local cannot respond to user input. Only after pressing a special key "local" on the front panel of the instrument can the instrument respond to the local input. User input set...

Problems solved by technology

[0006] However, with the development of intelligent measuring instruments, the functions of the instruments are becoming more and more complex, and the data resources that the instruments need to process are increasing, and the cost of maintaining the synchronization of data resource items is getting higher and higher. Experience, multiple data resource items also need to be associated, so that after the user completes the setting of a parameter, other associated parameters can be automatically set

[0007] For modern intelligent instruments, the existing technical solutions define and store the local interface data resources and remote interface data resources separately, which will lead to a large amount of data redundancy and space waste; in order to complete the synchronization of data resource items, the existing technical solutions need to be maintained A huge synchronous data mapping table. When the local interface data resource item is changed, query this huge synchronous data mapping table to synchronously change the remote interface data resource item. Conversely, when the remote interface data resource item is changed, it also needs to be queried In this table, modifying the local interface data resource items synchronously is very inefficient. At the same time, the maintenance cost of the synchronous data mapping table will become larger and larger as the data grows, and the probability of errors will also increase accordingly; The existing technical solutions to realize the automatic setting of associated parameters also need to maintain another associated parameter table, so that when the local interface data resource item is changed, the local associated parameter table is first queried to complete the automatic setting of local parameters, and then according to the associated Query the synchronization data mapping table one by one for parameter items, and modify the corresponding remote interface data resource items one by one. On the contrary, when the remote interface data resource item is changed, first query the remote associated parameter table to complete the automatic setting of remote parameters, and then one by one according to the associated parameter item Query the synchronous data mapping table, and modify the corresponding local interface data resource items one by one; the synchronous data mapping table and the associated parameter table of the existing technical solution need to be manually established and maintained, the maintenance cost is high, the flexibility is poor, and it is difficult to meet the existing data resources. management needs
