RFID-based soil sampling and automatic marking device

Abstract

The invention relates to the technical field of quick identification of soil samples. The invention discloses a RFID (Radio Frequency Identification)-based soil sampling and automatic marking device. The device comprises a soil sample marking management module (1), a tag read-write module (4), a sampling drill (6), a soil sample box (8) and a RFID marking tag (9). The soil sample marking management module (1) is used for acquiring soil sample information, and transmitting the acquired soil sample information to the tag read-write module (4); the tag read-write module (4) is used for writing the soil sample information into the RFID marking tag (9); the tag read-write module (4) and the soil sample box (9) both are located in the sampling drill (6); and the RFID marking tag (9) is located on an external surface of the soil sample box (8). The RFID-based soil sampling and automatic marking device can implement high-efficiency soil sampling and automatic marking of soil sample information.

Description

technical field [0001] The invention relates to the technical field of rapid identification of soil samples, in particular to an RFID-based soil sampling and automatic identification device. Background technique [0002] To ensure my country's food security and promote agricultural production, efficiency and income, the key is to manage the soil well. In my country's agricultural production, there are generally negative problems such as excessive input of chemical fertilizers, low utilization rate, heavy environmental pollution and decreased soil fertility. Effective acquisition of soil main nutrient information and scientific guidance of chemical fertilizer application are the keys to realize cost-saving and efficiency-enhancing, perfect soil testing and formula fertilization and implement "fertile soil engineering" in the practice of precision agriculture. [0003] Routine soil nutrient information acquisition mainly includes field sampling, sample pretreatment and extrac...

Problems solved by technology

The conventional field sampling process uses manual handwriting to record sampling information with paper labels. The main problems are as follows: 1) The information of soil nutrient pretreatment and testing links still needs to be supplemented and entered, and the efficiency of manual operation is low, and the rate of misuse is high; The quality label has a small amount of information and cannot include important information such as soil sample location information, planted crops, soil type, and previous fertilization, and is easily stained and cannot be reused; 3) The information between field sampling and sample testing is disconnected, and testing results are shared Low rate and utilization
