The obtained difference between result, the smaller passage consistency of this species diversity are better.Since the system uses moving detection vehicle formulas
Structure and the structure only have one group of LED, PD this allow for interchannel and does not have any detection error, and other previous schemes due to
There are multiple groups LED, PD so will appear the difference of interchannel detection data.
2. Material Cost reduces: due to having used detection vehicle type structure, this system only use one group of LED, PD(to exist
A PD and multiple LED is used in the system).It will be one corresponding with the LED of traditional each wavelength of solid-state Physico-chemical tests
A large amount of cost is reduced for the structure of PD, especially cost-effectiveness more highlights in the case where multichannel multi-wavelength.
3. reduce debugging complexity: traditional solid-state Physico-chemical tests system debug process is very cumbersome, channel more it is more then
PD, LED are more, and debug time is longer, but structure used in the present invention to debug abnormal convenient, this is embodied in:
1. due to there was only one group of LED, PD so only needing to debug the LED of each wavelength respectively.
2. due to using dismountable modular construction, and the original part for being related to consistency and precision problem is all set
Meter is in dismountable module, so this makes debugging that can complete that (independent tooling can be used outside the system with off line
It is refilled in detection system after unified debugging calibration).
The invention has the advantages that
(1) present invention has the characteristics that structure is simple, is convenient for operation, compact compared with prior art.Due to using LED to make
For light source with traditional spectrophotometer using spectroscope generate determine wavelength form compared with firmer antidetonation, in special field
There is inborn advantage under environment.
(2) position is relatively fixed under the action of elastic slice after cuvette insertion, to the repeatability of identical pattern detection data
It plays a key effect.Traditional LED physics and chemistry monitoring system insertion cuvette, which does not position each insertion position, some differences
Influence detection accuracy.
(3) it is detected only with one group of detecting element, production cost can be substantially reduced, avoided because of the first device of different detections
The individual difference of part causes interchannel difference and the influence to detection data.Traditional Physico-chemical tests module is due to there is multiple groups detection
Element, and between original part there are the difference of electric property and parameter consistency cause interchannel difference obviously need constantly debug with
Removing difference, which increase debugging costs.
(4) detecting element LED lamp panel and PD plate support warm connection function, and spigot design has protective device, detecting element
Wrong plug device of design itself, can carry out quick-replaceable.
The beneficial effects of the present invention are: its structure is simple, is convenient for operation, entire detection system is only with a pair of of detecting element
(LED circuit board and PD circuit board), and position is relatively fixed after cuvette insertion, avoids the individual because of different detection components
The influence of difference and different detection position differences to detection numerical value.And three kinds of differences are gathered inside a LED circuit board
LED light spectrum, integrated level is very high, machine compact, lighter in weight, and production cost is greatly reduced.Since detection part is
Mobile, easily, spectral frequency can be replaced arbitrarily for replacement detecting element (LED circuit board and PD circuit board), without
Dismantle machine.The system can detecte the sample in any notch by software control, greatly shorten detection time, improve inspection
Survey efficiency.
