Laboratory instrument linking system and method based on intelligent handheld terminal

Abstract

The invention provides a laboratory instrument linking system and method based on an intelligent handheld terminal. The system comprises an laboratory information system server, an instrument link server, a plurality of analysis instruments, the intelligent handheld terminal and a protocol converter, wherein the plurality of analysis instruments are connected to the protocol converter through RS232 interfaces, the protocol converter is connected with the instrument link server through a network, the instrument link server and the laboratory information system server are connected and share related information including user names, passwords and the like, and the intelligent handheld terminal and the instrument link server are connected wirelessly; and the intelligent handheld terminal is provided with a code label scanning device for the plurality of analysis instruments and test samples, and thus, a convenient function of manually matching sample numbers is provided and test data can be input manually.

Description

technical field [0001] The present invention relates to the technical field of laboratory testing, and in particular, the present invention relates to a laboratory instrument connection system and method based on a handheld intelligent terminal. Background technique [0002] When laboratories use various information systems, such as LIMS (Laboratory Information Management System), ELN (Electronic Laboratory Notebook) and LIS (Laboratory Information System), it is generally necessary to collect the test results of various laboratory analytical instruments , used to generate test report or experiment report. In various laboratories, the analytical instruments used can be divided into three categories according to the type of data interface configured, including instruments with a PC workstation, instruments without a PC workstation but with an RS232 data interface, and instruments without any Instruments with data interface. Some of these instruments have no RS232 interface ...

Problems solved by technology

The practice of placing a PC next to each instrument in order to avoid frequent movement of personnel needs to be equipped with many PCs and occupy a large amount of laboratory tabletops. The requirements for user names and passwords also make operators feel cumbersome, so most operators are unwilling to accept this automatic data collection method, but rather use manual methods to connect these instruments without PC workstations but with RS232 interfaces to those without any data. The interface instruments are treated together, that is, the test results of the instruments are first recorded on paper, and then these results are input into the information system through the client PC. This method of manually transcribing data greatly increases the error rate, and may not comply with the relevant laboratory specifications
