Fruit maturity detection method based on color sensor

Abstract

The invention relates to a detection method for forecasting fruit maturity based on fruit skin color and environmental temperature. According to the method, an intelligent color sensing module and an integrated temperature sensor based on the chip of a wireless singlechip CC2430 are installed in a fruit tree for comprehensive detection and judge of the fruit maturity. Onsite measuring sensor networking is carried out through a Zigbee module and monitoring data low power consumption wireless transmission is realized. A frequency signal outputted from the color sensor is subjected to signal conditioning, digitization and parameter correction so as to obtain a RGB parameter of the fruit surface color. An analog signal outputted from the temperature sensor undergoes AD conversion and filtering correction and then is used as a factor for judging the fruit maturing trend. The above parameters undergo multi-sensor data fusion and analysis and then the fruit maturity can be evaluated and simultaneously the fruit maturing speed can be forecasted. The method can be used for remote and nondestructive detection of fruit maturity. Therefore, managers can master fruit harvest time flexibly, thus minimizing economic loss of orchard workers.

Description

technical field [0001] The invention relates to the application field of identification of fruit surface color and wireless data transmission technology, and the method is used for remote monitoring of fruit ripeness in an orchard. Background technique [0002] China is very rich in agricultural resources and there are many kinds of fruits, but the rot and deterioration and quality decline caused by backward picking and storage technology cause serious losses every year. At present, the informatization of agricultural production management is not high. For example, during the fruit ripening period, fruit farmers need to know the ripeness of the fruit in time to facilitate picking and avoid fruit overripe and rot. However, the current agricultural production cannot effectively Realize informatization and intelligent management of fruit maturity, thus increasing the management cost of fruit farmers and reducing the normal income of fruit farmers. Therefore, it is particularly...
