Step S240, obtaining the volume L through the preset detection cavity specification data and the acquired height H.
The detection cavity specification data comprise the cross-sectional area of the detection cavity, and of course, when the detection cavity is of a regular structure (such as a cylinder structure with equal width up and down), the product of the cross-sectional area and the height H is the volume L, and when the detection cavity is of an irregular structure, the volume of each section needs to be calculated in a segmented mode and then added.
The height sensor may be a capacitive level gauge or an ultrasonic sensor.
Specifically, when the height sensor is a capacitance liquid level meter, the capacitance liquid level meter is arranged on one side of the detection cavity wall, and the obtaining of the height H of the residual liquid to be detected in the detection cavity comprises the following steps:
Acquiring a plurality of real-time capacitance values of a capacitance liquid level meter;
When the variation values of the continuous multiple real-time capacitance values are smaller than the preset value, the final value of the real-time capacitance values is obtained to obtain the height H.
The capacitance liquid level meter is a device for converting the position change of a measured object into capacitance, has the characteristics of simple structure, high resolution, reliable operation and quick dynamic response, is applied to the recovery of residual liquid and is used for detecting the height H in a detection cavity, the quick detection can be realized, and the detection result is accurate.

In step S410, when the height H is obtained and the height H is greater than the threshold Hq, the chemical component analysis device is started to obtain the component M of the residual liquid to be measured. When the residual liquid is too small, the chemical component analysis device is likely to be difficult to detect the residual liquid when the minimum volume is not met, so that the analysis device is started when the residual liquid is larger than the minimum volume, and the threshold Hq is the height of the residual liquid corresponding to the preset minimum volume.
The optical spectrum analysis device mainly uses optical theory as a basis and takes the interaction of the substance and light as a condition to establish the interrelation between the molecular structure of the substance and the electromagnetic radiation so as to analyze and identify the component M of the residual liquid to be detected.

In step S242, the volume L is obtained by the bottom area S, the height H 'and the volume Lz, wherein l=s' ×k-lz±w, W is a preset error value.
That is, when the height H of the residual liquid to be measured is smaller than the threshold Hq, it is proved that the residual liquid to be measured is insufficient at this time, and the component M cannot be accurately obtained by analyzing the residual liquid to be measured, then the residual liquid to be measured needs to be diluted at this time, the diluted height H 'of the medical residual liquid is obtained, and then the volume L is calculated by the diluted height H' of the medical residual liquid. More specifically, dilution may be performed by adding sterile water for injection or fresh sterile distilled water for dilution in order to prevent the residual liquid from being too small to calculate the height and to increase the volume for the analysis of the components, so long as the diluent does not react with the solute of the stock solution after the diluent is added to affect the analysis of the components.

step S414, comparing the current component spectrum with a preset standard component spectrum template;
And S416, extracting a component result corresponding to the standard component map when the comparison result meets the preset condition to obtain a component M.
