Forest fruit vibration harvesting dynamic signal detection system

Abstract

The invention discloses a forest fruit vibration harvesting dynamic signal detection system comprising a main processing module, a vibration acquisition module, a power supply energy supply module, a USB serial port module, a data storage module and a data transfer module; the main processing module is connected with the vibration acquisition module through an IIC interface; IIC transferring process is carried out for vibration signals collected by the vibration acquisition module; a SPI interface can store the processed vibration data into the data storage module; the power supply energy supply module provides working voltage for the whole system; the data storage module transfer data to a host computer through the data transfer module; the main processing module is connected with the host computer through the USB serial port module. The forest fruit vibration harvesting dynamic signal detection system is simple in structure, convenient in making, low in fault rate, easy to promote, can effectively obtain fruit vibration and bumping conditions in the vibration harvesting process, thus providing technical support for developing vibration harvesting equipment with high efficiency and low damage .

Description

technical field [0001] The invention relates to a vibration signal detection system, in particular to a dynamic signal detection system for fruit vibration harvesting. Background technique [0002] In recent years, China's annual output of forest fruit is about 261.4224 million tons, accounting for 15.2% of the world's total output value, and nearly half of the fruit directly enters the fresh fruit market after picking. However, the low productivity of manual picking and high labor cost are the severe challenges faced by the development of forest and fruit industry at this stage, and the key to deal with this challenge is to vigorously develop mechanized harvesting technology. [0003] While promoting the mechanized fruit picking technology in an all-round way, the impact damage of the picking machine to the fruit during the harvesting process is always the focus of attention. With the development of modern agriculture, impact damage has become an important factor affecting...

Problems solved by technology

[0004] Most of the previous studies have done a lot of analysis and experiments on the transmission law of vibration energy in the tree. By arranging acceleration sensors on the tree, the vibration conditions at different positions of the tree can be obtained, or the sensors can be placed on the fruit for vibration detection. However, when the fruit When the mass is small or the mass of the sensor is large, it will affect the detection results, causing the test results to deviate from the actual situation

Moreover, a large number of sensors not only increases the cost of use but also reduces the operability, and requires professionals, which is not conducive to popularization
