Embodiment Construction

[0022] The device and technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Spectrophotometer structure of the present invention such as figure 1 As shown, it mainly consists of three parts: spectroscopic system, data acquisition and control system and remote operating system. The spectroscopic system mainly includes four parts: light source, monochromator (or polychromator), sample chamber and detector (PMT or CCD). The optical path of the spectroscopic system is different according to the scanning and non-scanning signal acquisition methods. For the scanning type, the light beam is emitted by the light source, firstly passed through the monochromator, then irradiated on the sample, and finally reflected or transmitted by the sample. The light intensity signal is detected by a photomultiplier tube; for the non-scanning type, the light beam is emitted by the light source, first irra...

Abstract

The invention relates to a remote accessing spectral photometer, including spectral system, data collecting and control system and remote operating system, where the data collecting and control unit is connected with the spectral system through data collecting card and network server through network device to provide remote interface for operating terminals, each of which is connected with the data collecting and control unit through a remote terminal interface, by accessing the data collecting and control unit, further sampling spectrum and processing data. It can conveniently implement distant and multiuser use of the spectral photometer for spectral measurement, able to meet demands in some applications and effectively enhance utilization ratio of apparatus.

Description

Technical field: [0001] The invention relates to a spectrophotometer, in particular to a spectrophotometer with a remote access function, and belongs to the field of spectrophotometry technology and network technology. Background technique: [0002] Spectrophotometer is the most basic measuring instrument for substance detection and analysis. play an important role in the field of application. [0003] Due to the advancement of science and technology, spectrophotometers are constantly developing. In addition to changes in the spectroscopic system, their output devices and control systems are also constantly evolving. The output devices of early spectrophotometers were mainly direct-reading meters and X-Y recorders. Their control systems were generally fixed on the main body of the spectrophotometer and directly controlled by the buttons and knobs on the instrument. With the development of computer technology, the spectrophotometer gradually adopts single-chip microcomputer...
