Method and system for compensating fixed tooth deviation

Abstract

The invention discloses a method and a system for compensating fixed tooth deviation. The method comprises the following steps of: scanning and recording the number and the widths of teeth of a reaction disc of a full-automatic biochemical analyzer; optionally determining a reference tooth from the teeth of the reaction disc of the full-automatic biochemical analyzer; calculating the deviation between each tooth and the reference tooth by using the reference tooth as a reference position; and rotating the reaction disc according to the sum of the step number of a motor of the full-automatic biochemical analyzer and the deviation, and starting a system which implements the method. The reaction disc is scanned and the reference tooth is selected first, then the deviation between each tooth and the reference tooth is determined according to the reference tooth, and finally the reaction disc rotates according to the sum of the step number of the motor of the full-automatic biochemical analyzer and the deviation, so that the shortcoming of inherent deviation in a positioning tooth machining process is overcome, the positioning accuracy of the reaction disc is improved, a cuvette on the reaction disc can accurately reach a specific position, and the measuring efficiency of the full-automatic biochemical analyzer is improved.

Description

Technical field [0001] The invention relates to a reaction plate used for a full-automatic biochemical analyzer to carry a cuvette, in particular to a method and a system for compensating the deviation of a fixed tooth. Background technique [0002] The automatic biochemical analyzer is an instrument that measures a specific chemical composition in body fluids based on the principle of photoelectric colorimetry. Because of its fast measurement speed, high accuracy, and small consumption of reagents, it has been widely used in hospitals, epidemic prevention stations, and family planning service stations at all levels. However, due to the inherent deviation in the machining of the positioning teeth of the reaction disk, for example, when the reaction disk rotates a fixed tooth, the theoretical number of steps to control the rotation of the stepping motor is N steps, but due to errors in the machining, the position optocoupler detects the fixed tooth The number of steps rotated dur...

Problems solved by technology

However, due to the inherent deviation in the mechanical processing of the positioning teeth of the reaction disk, for example, when the reaction disk rotates a fixed tooth, the theoretical number of steps to control the rotation of the stepping motor is N steps, but due to the error in the mechanical processing, the position photocoupler detects the fixed teeth. The number of steps rotated when the signal is turned is M steps, resulting in an error of (N-M) steps, which causes a certain error when the reaction plate stops positioning, which in turn affects the position of adding samples, adding reagents and stirring, which limits the position to a certain extent. performance of the instrument, reducing its measurement efficiency
