Technical Field

The invention relates to the technical field of automatic testing, in particular to a PXI bus switch module control system and method.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The PXI bus switch module is a central hub for information exchange between the PXI bus automatic test system and the to-be-tested piece. Through various switch modules, the system can inject various control signals or excitation signals into any input port of the tested object, and can automatically switch the information of the output port of the tested object to corresponding test equipment, so that the automatic test operation of the PXI bus test system is realized, the test time is shortened, and meanwhile, artificial errors in the test process are reduced. The PXI bus switch module has the characteristics of flexible topological structure, high integration level, good environmental adaptability, multiplexing, strong expansibility and the like, and can better meet the requirement of signal switching. The PXI bus matrix switch module plays an important role in an automatic test system, and is widely applied to a weapon equipment test system.

Software design based on various switch modules is also crucial. Due to the difference of the switch types, the switch numbers and the realized functions of the switch modules, different switch modules need to develop different switch software for control. Product developers need to spend a great deal of time on development, and maintenance of products is easy to make mistakes, so that the development efficiency of software and the code quality are generally low.

The specific design style of the conventional switch module software is shown in fig. 1, and each switch module needs to develop independent switch module software, including an independent user interface and a virtual instrument driver. Due to the fact that program developers have different design ideas, switch module software interfaces of the same type are complex and various and different, and the user experience effect is poor. Multiple switch modules need multiple sets of different switch software, new switch modules are added, corresponding switch software needs to be re-developed, and the development process is complex.

In summary, the conventional PXI bus switch module software design method has the following disadvantages:

1) the expansibility is poor, a new switch module is added, corresponding switch software needs to be re-developed, and the development process is complicated.

2) The universality is poor, each switch module corresponds to respective switch software, multiple switch modules need multiple sets of different switch software, and the software development mode has a large amount of repeated development.

3) The switch modules of the same type have complicated software interfaces and poor user experience effect.
