The invention discloses an automatic soil component content detection control device. The automatic soil component content detection control device comprises a light source, a photoelectric detector, a pre-amplifier, a phase-sensitive detector, a controller, a display, a sample bearing platform, a weighing sensor, an A / D (Analog to Digital) converter and a horizontal detector, wherein the horizontal detector is arranged at the bottom part of the sample bearing platform and is used for detecting whether the sample bearing platform is in a horizontal state or not so as to obtain a detection result; the weighing sensor is used for weighing a to-be-detected soil sample in the sample bearing platform so as to obtain an analog signal and obtaining a digital signal through conversion of the A / D converter; the controller is used for receiving the detection result of the horizontal detector, obtaining a weight value of the to-be-detected soil sample and component contents of the to-be-detected soil sample according to the received digital signal when the detection result shows that the sample bearing platform is in the horizontal state, and controlling the display to display the obtained weight value and component contents of the soil sample. According to the automatic soil component content detection control device disclosed by the invention, a horizontal detecting function is added, so that convenience is provided for multi-directionally and accurately detecting components of the to-be-detected soil sample, the structure is simple, and implementation is convenient.
Description
technical field [0001] The invention relates to an automatic soil component content detection and control device, which belongs to the technical field of soil detection equipment. Background technique [0002] Since ancient times, soil has always been the source of food and clothing and the basis of survival for the majority of farmers in our country. Even in modern economic life, soil is still the most basic factor of production and the carrier of various economic relations. However, with the rapid development of the modern economy, the discharge of environmental pollutants is increasing day by day, and the environmental pollution and ecological damage are becoming more and more serious, which has brought serious pollution to the soil on which human beings depend for survival. [0003] Soil is the main body of nature composed of layers of mineral components of varying thickness. The difference between the soil and the parent material layer is manifested in the morphology, ...
