Control system capable of recognizing types of fruits and vegetables in intelligent food fresh keeping refrigerator

Abstract

The invention discloses a control system capable of recognizing the types of fruits and vegetables in an intelligent fresh keeping refrigerator. The control system comprises a central processing unit, a circuit substrate, a pressure sensor, a humidity sensor, a spraying device, a camera, a graphics processing unit and a data storage device. The circuit substrate is connected with the central processing unit. A fresh-keeping chromatic lamp is arranged on the circuit substrate, and comprises a red LED lamp bead, an orange LED lamp bead, a yellow LED lamp bead, a green LED lamp bead, a blue LED lamp bead, an indigo LED lamp bead and a purple LED lamp bead. The pressure sensor, the humidity sensor, the spraying device, the camera, the graphics processing unit and the data storage device are connected with the central processing unit. The central processing unit can control the fresh-keeping lamp beads of various colors on the circuit substrate individually, so that the fresh-keeping lamp is turned on and the luminous intensity is regulated according to the weights and the types of the fruits and vegetables in a fresh-keeping room.

Description

technical field [0001] The invention relates to a control system of an intelligent fresh-keeping refrigerator capable of identifying types of fruits and vegetables, and the control system is used for intelligent fresh-keeping of fruits and vegetables inside the refrigerator. Background technique [0002] Refrigerators are indispensable electrical appliances in modern life. Putting vegetables or fruits in the refrigerator can extend their shelf life. However, since vegetables and fruits cannot continue to carry out photosynthesis, the continuous consumption of respiration will accelerate the deterioration and decay of vegetables or fruits; and the implementation of light on plants in the refrigerator can allow vegetables to continue photosynthesis to offset the generation of respiration. consumption, effectively delaying the rotting speed of vegetables and achieving the effect of keeping fresh. Many existing refrigerators use an air-cooling system. The advantage of the air-c...

Problems solved by technology

Many existing refrigerators use an air-cooling system. The advantage of the air-cooling system is that the cooling efficiency is very high. However, the air-cooling refrigerator will dry the vegetables and fruits in the refrigerator and make them lose moisture quickly. In this way, the moisture in the vegetables and fruits will be reduced. It is steamed dry and loses its original taste, and none of the existing refrigerators can implement the corresponding amount of light according to the amount of fruits and vegetables inside.

There are refrigerators using vacuum fresh-keeping in the prior art, but their structures are complex and require additional air extraction devices, which will also bring additional noise and power consumption. Although there are refrigerators using photosynthetic fresh-keeping lamps in the prior art, each The sensitive bands of vegetables are not the same, and it cannot implement different bands of light for different fruits and vegetables, let alone adjust the corresponding light according to the amount of fruits and vegetables
