Abstract

The invention relates to the technical field of soil environment monitoring, and particularly discloses a soil detection method and system for soil improvement. The method comprises the steps of obtaining a real-time output signal of a sensor, identifying the starting moment of fluctuation change of the signal to define a monitoring period, taking the signal in the period as a parameter signal, dividing the parameter signal into parameter groups to generate a comprehensive score representing the soil state, comparing the comprehensive score with a preset deviation value to judge whether a correction triggering condition is met, and issuing a correction instruction if the correction triggering condition is met, and calculating a correction time node based on the response time of the sensor and a reference factor to serve as the execution moment of correction operation. The invention makes a decision through comprehensive scoring, can effectively smooth the instantaneous signal interference, and enhances the timeliness and the accuracy of system response by accurately calculating the correction time node, thereby improving the overall accuracy and the reliability of detection.
