Abstract

A method for realizing remote reconfiguration by using a reconfigurable PXI serial communication card relates to the PXI reconfigurable serial communication technology. It solves the problems of poor versatility and inconvenient maintenance of the PXI 3U board. The reconfigurable instrument platform of the present invention is connected to the function board by stacking, the function board is arranged on the back of the reconfigurable instrument platform and is detachable, and the connection signal is the I / O signal of the FPGA. After establishing a complete network server, the FPGA receives the configuration file sent by the remote configuration computer. The invention can solve the problems of large number of different communication protocol cards, great difficulty in system integration, and high cost through the reconfiguration function, realizes the serial communication function of different protocols, and has the advantages of high flexibility, strong versatility, and easy upgrade. The invention is applicable to test or other systems.

Description

technical field [0001] The invention relates to a PXI reconfigurable serial communication technology. Background technique [0002] For different measured objects, generally need to use different serial communication such as RS422 or RS485, and for different measured objects, often need to use different communication protocols, such as HDLC, SDLC, UART, etc. The PXI reconfigurable serial communication card designed this time can realize the mutual switching of different communication level standards and different communication protocols through local or remote reconfigurable methods. [0003] In the field of testing, it is often necessary to use different communication protocols. Traditional PXI 3U boards integrate reconfigurable instrument platforms and function boards on one board, resulting in poor versatility of PXI 3U boards. If different communication cards are used to implement different communication protocols, device integration is difficult and costly. When diffe...
