Vegetable and fruit storage equipment based on PLC

Abstract

The invention discloses vegetable and fruit storage equipment based on PLC. The equipment comprises a housing, a control seat is arranged at the bottom end of the housing, a gravity plate is arrangedat the bottom of the housing, a plurality of matching rods are arranged at the bottom end of the gravity plate, an induction spring matched with the control seat is arranged at the bottom end of the matching rod, a spraying cover matched with the control seat is arranged at the top end of the housing, a control shunting frame is arranged at the top end of the spraying cover, a water receiving pipematched with the control shunting frame is arranged at the top end of the control shunting frame, a first water outlet pipe is arranged in the middle of the bottom end of the control shunting frame,an atomization spraying head is arranged at the bottom end of the first water outlet pipe and sleeved with a shunting spraying frame matched with the atomization spraying head, and connecting pipes matched with the control shunting frame are arranged on the two sides of the top end of the shunting spraying frame respectively. The equipment has the beneficial effects that effective automatic control over humidity, temperature and moisture of the equipment is effectively guaranteed, and the equipment is more flexible and practical.

Description

technical field [0001] The invention relates to the field of PLC control, in particular to a storage device for fruits and vegetables based on PLC control. Background technique [0002] The PLC control system is a new generation of industrial control devices formed by introducing microelectronics technology, computer technology, automatic control technology and communication technology on the basis of traditional sequence controllers. The purpose is to replace relays, execute logic, timing, Sequence control functions such as counting, according to a vegetable and fruit fresh-keeping cabinet disclosed in Patent No. CN109393848A, the device can separately adjust the temperature in each section, adapt to the storage of various fruits and vegetables, and make the cold air in the section form a convection cycle, which has a good refrigerated, but it cannot be assisted by PLC control, and the temperature and humidity inside the equipment cannot be guaranteed to be constant. In the...

[0002] The PLC control system is a new generation of industrial control devices formed by introducing microelectronics technology, computer technology, automatic control technology and communication technology on the basis of traditional sequence controllers. The purpose is to replace relays, execute logic, timing, Sequence control functions such as counting, according to a vegetable and fruit fresh-keeping cabinet disclosed in Patent No. CN109393848A, the device can separately adjust the temperature in each section, adapt to the storage of various fruits and vegetables, and make the cold air in the section form a convection cycle, which has a good refrigerated, but it cannot be assisted by PLC control, and the temperature and humidity inside the equipment cannot be guaranteed to be constant. In the vegetable and fruit storage equipment, because the fruits and vegetables need to ensure the humidity and temperature to ensure freshness, the PLC control is used to provide accurate and automatic control for the equipment. The humidification and spraying function can improve the storage time and quality of vegetables and fruits without wasting water and damaging the fruits
