Method and apparatus for monitoring concentration of reagent, electronic device, and computer readable storage medium

An apparatus for monitoring a concentration of a reagent, comprising:

• a processor;
• a density meter operatively connected to the processor;
• and
• a memory including:
• a first acquiring module, configured to cause the processor to acquire a first concentration of a current reagent measure by the density meter during filling of the current reagent with a preset concentration from a reagent bottle into a vessel via a liquid path;
• a second acquiring module, configured to cause the processor to acquire a current volume of carryover left in the vessel and the liquid path determined in a process of filling a previous reagent into the vessel and draining the previous reagent out from the vessel;
• a determining module configured to cause the processor to:
• acquire a second concentration of the current reagent measured by the density meter during draining of the current reagent from the vessel to the reagent bottle via the liquid path, and
• determine, based on the preset concentration, a volume of the reagent bottle and the current volume of carryover, a third concentration of the current reagent after the current reagent is drained out from the vessel to the reagent bottle;
• an updating module configured to cause the processor to update the current volume of carryover left in the vessel and the liquid path based on the first concentration, the second concentration and the volume of the reagent bottle;
• and
• a reminding module configured to cause the processor to generate an electronic reminder signal to remind a user to replace the current reagent when the third concentration is less than a preset concentration limit and/or a refreshing module, configured to refresh the current reagent with a higher concentrated reagent.

An equipment for monitoring a concentration of a reagent, comprising:

• a density meter, a cache, a controller and a processor;
• wherein the controller is configured to control a current reagent with a preset concentration to be filled into a vessel from a reagent bottle via a liquid path, and to control the current reagent to be drained out from the vessel to the reagent bottle via the liquid path;
• the density meter is configured to measure a first concentration of the current reagent during the filling and a second concentration of the current reagent during the draining;
• the cache is configured to cache parameters including the preset concentration, a volume of the reagent bottle, a current volume of carryover left in the vessel and the liquid path, and a preset concentration limit;
• the processor is configured to:
• acquire the first concentration of the current reagent measured during the filling;
• acquire the preset concentration, the water concentration, the volume of the reagent bottle, the preset concentration limit, and the current volume of carryover left in the vessel from the cache;
• acquire the second concentration of the current reagent measured during the draining;
• determine a third concentration of the current reagent after the current reagent is drained out from the vessel to the reagent bottle based on the preset concentration, the volume of the reagent bottle and the current volume of carryover;
• determine an updated current volume of carryover left in the vessel and the liquid path based on the first concentration, the second concentration and the volume of the reagent bottle, and replace the current volume of carryover saved in the cache with the updated current volume of carryover;
• and
• when the third concentration is less than the preset concentration limit, generate a reminder signal to remind a user to replace the current reagent and/or refresh the current reagent with a higher concentrated reagent.
