Description

Technical Field

[0001] The present invention relates to the technical field of laboratory resource management, and in particular to an information management system for laboratory equipment. Background Art

[0002] With the continuous development of society and the continuous advancement of technology, quality has become a key factor in the competition between enterprises and products. In the context of increasingly fierce competition in the global market, enterprises not only need to produce high-quality products, but also need to ensure that these products are competitive in the market. Therefore, the quality inspection industry has gradually become more and more important, occupying an increasing share of the economic market. The country has also taken positive measures to promote the construction of a quality power, and has promulgated a series of laws and regulations on quality inspection, aiming to improve the quality level of products and services, strengthen market supervision, protect consumer rights, and promote enterprises to transform towards quality and innovation-driven. These laws and regulations require enterprises to establish an efficient, accurate and traceable quality inspection system to ensure that products meet relevant standards and specifications.

[0003] However, traditional quality inspection methods are limited in meeting the complex quality management needs of modern enterprises. Manual records, paper documents, and decentralized data storage and processing methods can no longer meet the requirements of efficient and high-quality quality management. Therefore, it has become an urgent need to manage the quality inspection process in an informationized manner. The information management system can centrally manage quality inspection data, information, and reports, improve data accessibility and availability, strengthen the real-time monitoring and traceability of quality inspection, reduce human errors and operational inconsistencies, and thus significantly improve the efficiency and accuracy of quality inspection.

[0004] The current information management system has the following shortcomings: 1. Most laboratory scientific research instruments and equipment are monitored by different monitoring systems. The monitoring system has a relatively simple function and cannot monitor instruments and equipment of different brands at the same time. The compatibility is poor, which makes the overall monitoring of the equipment more cumbersome and not conducive to timely discovery of problems in equipment operation; 2. There are many types of information management systems, including laboratory environmental conditions monitoring systems, video monitoring systems, and equipment monitoring systems. Each system operates independently; monitoring data is not conducive to integrated analysis, the data is relatively scattered, and it is impossible to transmit massive amounts at the same time, which reduces the efficiency of equipment management; 3. In traditional laboratory equipment management, manual records are prone to errors, data is difficult to trace, and equipment maintenance is not timely.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to provide a laboratory equipment information management system to solve the shortcomings of the existing technology. Summary of the invention

The records stored in the present invention are kept for at least 6 years. At the same time, it can also realize online scheduling of analytical data, automatic collection of analytical data, uninterrupted rapid recording, information sharing, and paperless monitoring of analytical reports.
