Intelligent granary control cabinet and use method

Abstract

The invention belongs to the field of automation control controlled by a PLC (programmable logic controller), and particularly relates to an intelligent granary control cabinet suitable for a granary and a use method of the intelligent granary control cabinet. The intelligent granary control cabinet comprises a circular inflation and air-conditioning unit, an intelligent ventilation unit, a grain condition detection unit and a safe warehousing unit, wherein the grain condition detection unit provides data support for the circular inflation and air-conditioning unit, the intelligent ventilation unit and the safe warehousing unit; a 1#PLC is arranged in the control cabinet, the 1#PLC analyzes and judges real-time data uploaded by PLCs of all the units, the units are actively coordinated to work in a matched mode, grain ventilation is not allowed and personnel are not allowed to enter the granary during circular inflation and air-conditioning operation, and at the moment, a granary door is automatically locked; and after the personnel enter the granary, the circular inflation and air-conditioning operation and the like are not allowed to be started, and at the moment, the program of the circular inflation and air-conditioning unit executes safety protection. Therefore, data sharing and mutual cooperation among the units provide guarantee for high-quality storage of grains in the granary and safe warehousing of personnel.

Description

technical field [0001] The invention belongs to the field of automatic control controlled by a PLC programmable controller, and specifically relates to an intelligent granary control cabinet suitable for granaries and a use method thereof. Background technique [0002] At present, the automation systems in the domestic grain storage industry mainly include grain situation detection systems, ventilation systems, nitrogen atmosphere control systems, video surveillance systems, etc., each system operates independently and each system has a set of control cabinets, which not only makes data interaction difficult but also affects The storage area is clean and beautiful, and currently there is no comprehensive monitoring system to provide guarantee for the safety of personnel entering the warehouse. Contents of the invention [0003] The invention includes a ring-filled air conditioning unit, an intelligent ventilation unit, a grain condition detection unit and a safe warehousin...
