The test strip includes a substrate, a detection area disposed on the substrate for dry chemical detection of the sample, a first identifier indicating manufacturer information, and a second identifier indicating test strip specifications. The controller controls the sample application device to apply the sample to the detection area of ​​the test strip for a dry chemical reaction, and controls the information acquisition device to acquire the detection information of the detection area, the manufacturer information of the first identifier, and the test strip specifications of the second identifier after the dry chemical reaction is completed. Based on the detection information, manufacturer information, and test strip specifications, the controller obtains and outputs the detection results, ensuring that each entered test strip information corresponds one-to-one with the currently used test strip, thus improving the accuracy of the detection results.

The invention provides a dual-wavelength dry chemical detection method and system. The method comprises the following steps: acquiring a first reaction stationary point signal of a first to-be-detected substance reaction area of a to-be-detected sample under a first wavelength and a second reaction stationary point signal of the first to-be-detected substance reaction area under a second wavelength; inputting the first reaction stationary point signal into a first concentration quantification model corresponding to the first to-be-detected substance to obtain a first concentration value; comparing the first concentration value with a preset concentration switching threshold value; if the first concentration value is smaller than the concentration switching threshold value, determining a concentration detection result of a first to-be-detected substance in the to-be-detected sample based on the first concentration value; and if the first concentration value is greater than or equal to the concentration switching threshold value, inputting the second reaction stationary point signal into a second concentration quantification model corresponding to the first to-be-detected substance to obtain a second concentration value, and determining a concentration detection result of the first to-be-detected substance in the to-be-detected sample based on the second concentration value. According to the invention, the detection result accuracy of dry chemical detection can be improved.
