A method for automatic determination of compensation coefficient by peristaltic pump

Abstract

The invention discloses a method for automatically determining a compensation coefficient by a peristaltic pump. First, two first optical fiber sensors are placed symmetrically on both sides of the bottom of a reagent bottle, and two second optical fiber sensors are symmetrically placed on both sides of the bottle mouth; then a main controller reads Take the initial compensation coefficient of the peristaltic pump; then, the main controller calculates the number of walking steps of the peristaltic pump according to the current initial compensation coefficient, and controls the stock solution barrel to extract the reagent to the reagent bottle; then check whether the barrel is empty, if it is not empty If the number of steps of the peristaltic pump is completed and the second optical fiber sensor is not triggered, the main controller increases the initial compensation coefficient; if the number of steps of the peristaltic pump has not been completed and the second optical fiber sensor is triggered, the main controller The controller reduces the initial compensation coefficient; when the number of steps of the peristaltic pump is satisfied and the second optical fiber sensor is triggered, it is determined that the reagent reaches the predetermined liquid level position, and the current compensation coefficient is finally saved. This case has the characteristics of short time, fast speed, simple method and high degree of automation.

Description

Technical field [0001] The present invention involves the field of reagent setting technology, which specializes in a method of automatic measurement compensation coefficient of a peristaltic pump. Background technique [0002] The peristaltic pump is large -scale in laboratory equipment because of its fast speed, high accuracy, and low cost, but due to the aging of the hose, it will affect the final output accuracy, and the common peristaltic pump does not have automatic compensation. Function, so it is necessary to manually add liquid compensation to the experimental personnel before use, which greatly increases the workload of the personnel and seriously restricts the scope of the use of the peristaltic pump. Invention content [0003] The purpose of the present invention is to provide a method of automatic measurement of the compensation coefficient of the peristaltic pump. Two sets of fiber -fiber sensors can be used to determine the fixed volume reagent, and the compensati...

Problems solved by technology

[0002] Peristaltic pumps are widely used in laboratory equipment because of their fast filling speed, high precision, and low cost. However, the aging of the hoses will affect the final liquid output accuracy, and common peristaltic pumps do not have automatic compensation. function, so it needs to be manually compensated by the experimenter before using it, which greatly increases the workload of the personnel and seriously restricts the scope of use of the peristaltic pump
