Embodiment Construction

[0025] The present invention mainly comprises two major parts:

[0026] (1) First code the hollow cathode lamps, formulate the code table, set the code resistance for the hollow cathode lamps of different elements, then connect them in series to the lamp pins, and store the code table into the microprocessor.

[0027] (2) Install a voltage divider circuit on the instrument. When the coded hollow cathode lamp is installed on the lamp holder, the coded resistor on the lamp pin will be connected to the voltage divider circuit. Using the voltage divider identification method, the divided voltage value will be read into the microprocessor, and press The code table automatically identifies what the coded lamp is an element lamp.

[0028] As shown in Figure 1, the encoding resistor of the present invention adopts 16 levels of voltage division, corresponding to the hexadecimal code 0 ~ F, and each lamp is coded with 2 bits, that is, two encoding resistors R need to be connected to the...

Abstract

This invention provides encoding hollow cathode lamp recognition device and its method. The device is made up by hollow cathode lamp that can encode voltage division electric circuit, analog-to-digital converter and microprocessor. The recognition method is voltage division recognition method; its procedures are that first element lamp encoding table is established. Then encoding resistance is series connected to lamp foot of the hollow cathode lamp. Thirdly, the lamp is fixed on multiple positions rotary lamp bracket. Fourthly, high order encoding resistance voltage division value is red. Fifthly, the high order code is ensured. Sixthly, low order encoding resistance voltage division value is red. Seventhly, the low order code is ensured. Eighthly, elements lamp coding table is found. Finally, what is the element of the lamp is ensured. This invention improves automation and intelligence of atomic absorbing spectroscope, and work efficiency of multi-elements continuous analyzing and testing.

Description

technical field [0001] The invention relates to a component analysis instrument, in particular to a coded hollow cathode lamp identification device and a method thereof. Background technique [0002] The hollow cathode lamp used in the atomic absorption spectrometer is a kind of light source that uses different element materials to fill the cathode, and emits the sharp line spectrum of the element after excitation, which can be used to analyze the content of the element in the sample with high sensitivity. High atomic absorption analysis. Therefore, hollow cathode lamps are simply called "element lamps". When multiple elements need to be analyzed, it is necessary to use multiple hollow cathode lamps with cathodes filled with corresponding elemental materials. [0003] Early atomic absorption spectrometers only had 1 or 2 lamp holders. When analyzing different elements, the lamps had to be changed manually and the existing positions had to be adjusted, which was inefficient...
