Method and system for solving communication interface data compatibility in replacement of old parts of instrument

Abstract

The invention relates to the field of instrument measurement and control, and discloses a method for solving data compatibility of a communication interface in replacement of an old component of an instrument, which comprises the following steps: S1) confirming bus interface types of a scientific instrument and a new component to be installed, and respectively connecting the scientific instrumentand the new component to be installed with a data adapter; s2) obtaining a communication protocol; s3) modifying data format adaptation software in the data analysis and forwarding software; s4) powering on the scientific instrument, the to-be-installed new part and the data adapter module and performing integration test; and S5) judging whether the communication between the scientific instrumentand the to-be-installed new component is normal or not. The invention provides a method for solving the data compatibility problem of the communication interface in replacement of old parts of the scientific instrument, the disadvantage caused by dependence on traditional hardware improvement is avoided, the data compatibility problem is solved by adding the data adapter between the scientific instrument and the parts, the universality is very high, and the model selection range of instrument accessories is enlarged.

Description

technical field [0001] The invention relates to the field of instrument measurement and control, in particular to a method and system for solving communication interface data compatibility in the replacement of old parts of the instrument. Background technique [0002] Large-scale scientific instruments are the integration of various cutting-edge technologies, and are often developed by integrating components provided by different countries and manufacturers. The communication bus and component interfaces are complex. During the long-term use of large-scale scientific instruments, part (or component) manufacturers often improve and upgrade the process, design, and software communication protocols. When old components fail, they cannot be replaced or updated due to compatibility issues, resulting in instrument downtime. , cannot be used normally. There is currently no unified solution to the above problems. Most of them request component manufacturers to customize products, ...

Problems solved by technology

During the long-term use of large-scale scientific instruments, part (or component) manufacturers often improve and upgrade the process, design, and software communication protocols. When old components fail, they cannot be replaced or updated due to compatibility issues, resulting in instrument downtime. , does not work properly

There is currently no unified solution to the above problems. Most of them request component manufacturers to customize products, or request large-scale scientific instrument manufacturers to upgrade the instrument control system. The above two methods generally have a long cycle and are expensive, especially the second one. The method may not be applicable due to factors such as the acquisition and bankruptcy of the instrument manufacturer
