business background
With the continuous advancement of science and technology and the continuous development of laboratory management needs, traditional laboratory management methods are facing many problems, such as the use of paper records and manual operations, easy loss of data and difficulty in tracing, low efficiency, complex processes, and insufficient quality management. Specifications etc. These problems have become bottlenecks restricting laboratory development and improving operational efficiency. At the same time, the inspection and testing industry also faces the following challenges:
(1) Unable to support large-scale data calculation and analysis**: In the early experimental data analysis calculations, the amount of data was small, and simple calculators and manual calculations were sufficient. However, as the amount of detection data increases, the early calculation methods can no longer meet the demand, and data analysis tools with better performance and stronger computing power need to be introduced.
(2) Sample data collection is slow and inefficient: **Before digitization, traditional data collection relied on manual data information collection. The paper-based collection method was slow in efficiency and had poor preservation.
(3) Poor data verification function and inaccurate verification results: **The traditional working mode may have problems such as incomplete data verification, too loose verification rules, and logical loopholes in the algorithm, resulting in inaccurate verification results. , affecting the validity and credibility of the data.
(4) Analysis report results are generated slowly and cannot meet user needs: **Early systems cannot meet the growing demand for today's data volume. Their performance when processing large-scale data is poor, resulting in analysis report generation taking a long time and unable to meet users' needs. The need for fast, real-time analysis and reporting.
(5) Opaque management of resources: **In laboratory work, information on sample consumables needs to be recorded manually in the traditional way and saved in paper files. This will lead to problems such as unclear preservation and traceability, failure to form a system for personnel training materials, and difficulty in controlling file permissions. The transmission of test reports and test data requires paper delivery, which not only wastes resources but also cannot guarantee the authenticity and timeliness of the data.
(6) Data cannot be shared (data island): **Data cannot be communicated between laboratories. For example, it is difficult for the quality management department to call the testing data of each laboratory, and data is easily lost. It is difficult to dig deep into the value.
How to solve these pain points
In order to solve these problems and challenges, digital systems have gradually become a trend in laboratory management and are gradually applied to laboratory management. Laboratory Information Management Systems (LIMS) came into being. The LIMS digital system can realize the digital collection, management and analysis of laboratory data and improve the reliability and accuracy of data. At the same time, it can optimize laboratory workflow, improve management levels and quality certification levels.
Laboratory Information Management System, also known as LIMS (Laboratory Information Management System, hereinafter referred to as LIMS), is composed of computers and application software and can complete the collection, analysis, reporting and management of laboratory data and information.
LIMS系统以实验室为中心，将实验室的业务流程、环境、人员、仪器设备、标物标液、化学试剂、标准方法、图书资料、文件记录、客户管理等等影响分析的数据因素有机结合起来，采用先进的计算机网络技术，数据库技术和标准化的实验室管理思想，组成一个全面、规范的管理体系，为实现分析数据网上调度、分析数据自动采集、快速分布、信息共享、分析报告无纸化、质量保证体系顺利实施、成本严格控制、人员量化考核、实验室管理水平整体提高等各方面提供技术支持，是连接实验室、采样现场、监管部门及客户信息的信息平台，同时引入先进的数理统计技术，如方差分析、相关和回归分析、显著性检验、累积和控制图、抽样检验等，协助职能部门及时发现和控制影响产品质量的关键因素。
The introduction of LIMS digital system can greatly simplify the laboratory management process. By replacing paper records and manual operations, the LIMS system can realize the electronic collection and storage of experimental data, avoiding the problems of data loss and difficulty in traceability. At the same time, the automation function of the LIMS system can speed up laboratory processes, improve work efficiency, and reduce human errors and duplication of work.

Technical points
(1) Multi-terminal cross-platform application
In the early LIMS system, report filling, modification and generation of inspection data were all completed through Excel. After entering the B/S era, LIMS systems need to be able to be used in real time on various terminal devices (such as computers, tablets, mobile phones, etc.). In this case, it becomes very inconvenient to fill in and modify data through Excel software. Therefore, how to directly operate reports on the browser and implement cross-platform applications is an important requirement for LIMS systems in the new era.
In the LIMS application system based on the browser/server (B/S) architecture, modules related to data filling, report analysis and display can be built based on front-end technology. With the help of SpreadJS, the pure front-end form control of Grape City Company, Excel can be migrated from offline to online, realizing the integrated process of data filling, analysis and report generation, and completely saying goodbye to dependence on Excel software. Through the nested technical solution, the system can realize the same form display method on the mobile terminal and desktop terminal.
