Abstract

The invention discloses a deep learning network based compost maturity real-time prediction method. The temperature, humidity and surface image depth feature vector in compost can be used as the descriptive characteristics of the compost; and on-line real-time monitoring of maturity can be realized with the help of the efficient learning capability of a deep learning method. A maturity predictionprocess begins from the real-time measuring of compost temperature and humidity and image acquisition; the method first performs pretreatment on an image, and the depth characteristics of the image can be extracted by a convolutional neural network (CNN); and then the combination of the compost temperature and humidity can be used as an input quantity during a maturity judging process, and sent into a recurrent neural network (RNN) to predict whether the current moment is mature or not. The relatively perfect, reasonable and accurate compost maturity real-time monitoring method can provide guidance for production.

Description

technical field [0001] The invention relates to a real-time prediction method of compost maturity realized by using information technology using compost temperature, humidity and image information through a deep learning network, belonging to the field of agricultural informatics. Background technique [0002] In agricultural production, in order to maintain and improve soil fertility, it is necessary to apply a certain amount of organic materials to the soil, and to use microorganisms to decompose these materials to a certain extent before application is called decomposing. The composting production mode is divided into static mode and dynamic mode, and the present invention takes the composting mode of linear fermenter as the research object. The width of the fermentation tank is generally 2.0-6.0m, the depth is 0.3-2.0m, and the length is 20-60m. The primary fermentation time of the compost is generally 15-25 days, and then the compost that has completed the primary ferm...
