Embodiment

[0026] Example: such as figure 1 As shown, the present invention obtains the titration result data of the titrator 1 by the potentiometric titrator control terminal 2; the titrator control terminal 2 is connected with the data acquisition machine 3, and the titration data is sent to the data acquisition machine 3, and the data is pushed by the data acquisition machine 3 After reaching the database 4, the operator can log in to the system at any terminal of the laboratory information management system terminal 5 to enter his own original record interface to select titration batches, complete the automatic collection of titration data by the potentiometric titrator, and perform subsequent inspection and testing operations.

[0027] Specific steps include:

[0028] 1. After a titration is completed, add relevant information such as the internal sample code, titration type, and inspection elements corresponding to each titration value in the collection program, and the system will...

Abstract

The invention relates to an automatic data acquisition system of a potentiometric titrator, belonging to an automatic data acquisition technology of the potentiometric titrator in the check test environment of the steel production process; the automatic data acquisition system comprises the potentiometric titrator, a titrator control terminal, a data acquisition device, a central data base and a laboratory information management system terminal, wherein the output of the potentiometric titrator is connected with the input of the titrator control terminal; the output of the titrator control terminal is connected with the input of the data acquisition device; the output of the data acquisition device is connected with the input of the central data base; and the output of the central data base is connected with the laboratory information management system terminal. The invention provides a scheme for checking and testing the acquisition of the originally recorded data, thus having great significance for realizing electronization and informatization in the whole checking and testing process of a laboratory, avoiding the error caused by manually copying and improving labor productivity of checking and testing.

Description

Technical field: [0001] The invention relates to an automatic data collection technology of a potentiometric titrator in the testing environment of the iron and steel production process. Background technique: [0002] At present, the metal group and raw material group in the chemical laboratory use the traditional chemical method for volumetric inspection, and the laboratory inspection results are calculated manually. Repeated transcription work still accounts for the vast majority of the daily workload, and volumetric titration with potentiometric titrator is an important part of the experiment. Mistakes in recording occurred during repeated transcriptions. Therefore, the automatic titration data collection system of the potentiometric titrator is of great significance to realize the full automation and informatization of the laboratory inspection process. Invention content: [0003] The purpose of the present invention is to realize the titration data automatic collect...
