Problems solved by technology

During the entire identification process, handles that are not related to the required identification modules are operated, which reduces the efficiency of module identification. When the module is replaced with a chassis slot, it is necessary to change the relevant identification fields in the program, which breaks the closed principle of the program for changes, which is not conducive to the project. development management of

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] The similar module identification method based on the module handle in the prior art opens all the local PCI interface devices, obtains the identification information through the module handle, executes too many useless operations, and is inefficient. When the slot position of the module in the chassis changes, for a chassis that does not support obtaining the slot position of the module, it is necessary to view and modify the program identification info...

Abstract

The present invention proposes a kind of PXI test module identification method of the same kind, comprises the following steps: programming device serial number to the unused register of external serial EEPROM of module device control chip; Operating specific I / O space of local computer to drive PCI bridge It is converted into an operation on the configuration space of the module device, matches user setting information, saves the device configuration address port information of the matching module; reads the device serial number of the saved module, matches the user setting information, identifies similar modules, and obtains the module control handle in reverse. The present invention uses the PCI configuration register manufacturer ID and device ID attributes and the device serial number programmed in the external serial EEPROM register of the control chip as the module identification information. In the module identification process, the module device is only opened once, and the module handle is obtained in reverse, and the efficiency is improved. High; programming the serial number of the device to the module can realize module registration and management, which is beneficial to the development and management of the project.

Description

technical field [0001] The invention relates to the field of PXI test modules, in particular to a method for identifying similar PXI test modules. Background technique [0002] PXI test modules have been rapidly developed and applied in the test field due to their small size, flexible plug-in combinations, and high integration efficiency. With the construction of a general platform for module systems and the improvement of integration, a set of PXI test module integration systems will appear There are cases of the same type of test modules, such as multiple local oscillator modules. [0003] The existing module identification method is based on the module handle. For an integrated system with only one functional module, before identifying the module, it is necessary to open all the local PCI interface devices to obtain the module handle. The vendor ID and device ID attributes are matched with the user setting information. When the same type of modules exist in the integrat...
