Data communication test system and method based on PXI synthesis instrument

Abstract

The invention belongs to the technical field of data communication. The invention discloses a data communication test system and method based on a PXI synthesis instrument. The system comprises a signal generation module, a data acquisition module, a frequency reference module, a frequency synthesis module, a multiplexing switch module, a down-conversion module, a digitizer module, an oscilloscopemodule, a universal meter module, a CAN communication module, a switch, a cable, a computer and the like. According to the optimal PXI instrument combination mode, the instrument optimal combinationcapable of meeting the requirements is derived according to the parameter information set by the user or the actual measurement value and used for achieving the needed functions, and therefore the working efficiency of the system is improved. The system is developed based on a LabVIEW language, a software interface capable of carrying out data interaction with a user is provided, and the user canset parameter information through the software or manually import or export configuration information and test data through the software.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to a data communication testing system and method based on a PXI synthesis instrument. Background technique [0002] The existing data communication test system designs the system solution, hardware, software and test method according to the requirement put forward by the user. Especially for complex functional tests and functional tests whose data exceeds the normal range, it is necessary to redesign a new system solution and test method. The system can meet the needs of users, but due to factors such as specific test requirements, single function and poor compatibility, a lot of manpower and material resources are invested in system design and maintenance, resulting in a large waste of resources. At the same time, in the data testing and communication process of the existing data communication testing system, due to the accuracy of the equipment, design loo...

Problems solved by technology

The system can meet the needs of users, but due to factors such as specific test requirements, single function, and poor compatibility, a lot of manpower and material resources are invested in system design and maintenance, resulting in a large waste of resources

At the same time, in the data test and communication process of the existing data communication test system, due to the accuracy of the equipment, design loopholes and human operation errors may lead to data loss and communication failure, making the system abnormal and unstable

[0003] To sum up, the problems existing in the existing data communication test system are: it can only meet specific test requirements, the equipment utilization rate is low, the compatibility is poor, and it is a great waste of hardware instrument resources and human resources

[0004] Difficulty in solving the above technical problems: the functional test is complicated, and a single instrument cannot meet the demand; the number of equipment is large, the accuracy is poor, and the operation is cumbersome
