[0002] Corn frost damage is an agricultural meteorological disaster that occurs in the warm seasons of spring and autumn when corn plants are in the early or late stages of growth and development. Due to the invasion of cold air from the north and ground radiation, the surface temperature drops below 0°C in a short period of time, causing damage to corn plants. Severe frost damage will cause a reduction in corn plant yields. In the cultivation of frost-resistant corn plants, frost test fields of corn plants will be conducted in the test fields to understand the cold resistance of corn. Since corn plants are already strong and upright in autumn, it is difficult to collect test field data and it is difficult to conduct test fields. Therefore, frost test field data are mostly collected in the test fields during the corn seedling stage in spring. At present, the frost test field data detection device commonly used in corn test fields mainly consists of a base, a collection rod, a temperature and humidity collection device, and an image collection camera. The collection rod is installed at the head of the test field, and the temperature and humidity collection device and the image collection camera are installed on the collection rod to collect the test field data of the test field.
