Remote system and remote method for controlling multiple pieces of PXI equipment based on TCP protocol

Abstract

The invention is applicable to the field of comprehensive electrical measurement technology improvements, and provides a remote method for controlling multiple pieces of PXI equipment based on a TCP protocol. The remote method comprises the steps that A, a control function of PXI equipment and a board card is divided into a control terminal module and a control service module; B, the control service module is deployed on the PXI equipment to control the board card on the equipment to operate; C, the control terminal module is deployed on an equipment control module to perform data instruction transmission; D, the control terminal module performs instruction data transmission with the control service module through a network protocol so as to complete a remote control test. According to the invention, a user operation terminal breaks away from an equipment execution terminal, control software is not required to be deployed on the PXI equipment, single piece of software can control multiple pieces of PXI equipment, and flexible deployment of the PXI equipment and software is facilitated.

Description

technical field [0001] The invention belongs to the field of comprehensive electric measurement technology improvement, in particular to a remote system and method for controlling multiple PXI devices based on the TCP protocol. Background technique [0002] The comprehensive test of the satellite is to detect the function of the satellite in the stage of satellite production and development, and to ensure the status of the satellite. Various ground equipment will be used in the process of the comprehensive test. Control is one of the key items of comprehensive testing, and PXI equipment is often used at this stage. [0003] PXI equipment mainly refers to a set of equipment composed of PXI chassis, PXI controller, PXI board and other hardware produced by NI Company selected and built according to actual needs, used to complete various tasks such as data acquisition, signal processing, and signal control. There are several functions, and its hardware configuration depends on ...

AI Technical Summary

Problems solved by technology

[0007] 1. Since the resources that PXI devices can provide are limited, such as the limitation of board slots on the number of boards and resources, and the performance of PXI controllers on the processing of high-speed or large data volumes, etc., if a single software can only Control a single device, then for the test task, the test function that its software can realize will be greatly restricted

[0008] 2. In the past, the control software can only be installed on the device itself to control the board. On the one hand, this leads to the limitation of a single software controlling a single device mentioned in the above question 1. On the other hand, the operation of the software is very difficult. the inconvenience

In addition, there are situations where the test computer and PXI equipment are deployed in completely different locations, which is quite inconvenient for testers
