Device and method for remote joint test of electronic equipment

Abstract

The invention discloses a device and a method for remote joint test of electronic equipment, and relates to the technical field of electronics, the electronic equipment remote joint test device comprises a plurality of driving terminals, the plurality of driving terminals are connected through optical fibers, each subsystem participating in system joint test is provided with at least one driving terminal, and communication and radio frequency signals of the subsystems are connected to the driving terminals. The driving terminal converts communication and radio frequency signals of the subsystem into optical signals, then the optical signals are compounded to an optical fiber and transmitted to another driving terminal at the distance, and the driving terminal converts the optical signals into corresponding radio frequency and communication signals and is crosslinked with the subsystem at the distance. The system supports communication signals and radio frequency signals at the same time and can be used in a long distance, so that subsystems can be distributed in respective sites and do not need to be concentrated in one place during system joint test, the working efficiency is improved, the cost-effectiveness ratio is reduced, and the working period is shortened.

Description

technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to a device and method for remote joint testing of electronic equipment. Background technique [0002] A system in the traditional sense is generally composed of several sub-systems that realize a single task, and the sub-systems are cross-linked through radio frequency signals and digital signals. In system research and development, production and maintenance, etc., it is necessary to connect the subsystems for joint operation and testing, that is, system joint test (referred to as joint test). Since there is an electrical connection relationship between communication and radio frequency signals between subsystems, the length of the connecting cable will affect the electrical indicators, such as radio frequency signals, the longer the connecting cable, the greater the signal loss. Therefore, when the system is tested together, it is usually required to gather ...

AI Technical Summary

Problems solved by technology

[0003] 1) The joint test requires a variety of equipment, multiple sub-systems, etc. to work together, and the shapes of the equipment are different, and the workload of logistics and transfer to the joint test site is relatively large

And if the joint test is staged, multiple round-trip transportation is required, which is inefficient;

[0004] 2) The joint test can only be started after all the sub-systems have completed their own debugging and testing. The debugging and testing progress of individual sub-systems will directly affect the progress of the joint testing of the entire system;

[0005] 3) It is necessary for the support resources and personnel of each subsystem to arrive at the joint test site

Moreover, in most cases, the independent debugging and testing of subsystems and the work arrangement of system joint testing cannot be fully balanced, and each team is forced to increase the number of resources and personnel;

[0006] 4) When there are many subsystems, a large enough joint test site is required to accommodate a large number of equipment, and the distance between each subsystem is different, which cannot meet the requirements of signal power and signal quality

[0007] 5) The method of concentrating all equipment together for joint testing will inevitably lead to excessive concentration of loads such as power supply and environmental control, and the site after targeted transformation must be used

Therefore, the site is not easy to adjust, which will inevitably lead to increased costs
