Circulation controller in granary

Abstract

The invention discloses a granary internal circulation controller, which comprises a box body and a box door, wherein an air switch, a motor controller module, an embedded control host, a wireless data transmission module, a switching power supply, a power surge protector, an AC contactor, a relay and an external wiring terminal; the motor controller module is connected with the air switch, the motor controller module is connected with the relay, the relay is connected with a power supply of a motor, and the relay is connected with the embedded control host; the power surge protector is connected with an incoming line power part; the wireless data transmission module is connected with the embedded control host through a serial port, the embedded control host is connected with an upper computer, a granary temperature sensor is connected with the embedded control host, the embedded control host is connected with the upper computer, the upper computer is connected with a grain condition detecting system, the grain condition detecting system is connected with a grain bulk sensor, and a liquid crystal display screen, a manual and automatic button as well as a circulation and fumigation button are connected with the embedded control host. By utilizing the granary internal circulation controller, the circulation and fumigation are realized, the efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of grain surface temperature detection equipment, in particular to a granary internal circulation controller, which realizes the temperature control and adjustment of the granary, and at the same time uses the internal circulation pipeline and fan to circulate phosphine gas from the grain surface to the grain pile through negative pressure. , to achieve internal circulation fumigation in the warehouse. Background technique [0002] Grain is a living body, and its production and consumption are unique. How to store food safely has become a worldwide problem, and the development of grain storage technology has important practical significance. Intelligent control technology has begun to be used in my country's grain storage, which has greatly improved the comprehensive technology platform and automation management level of grain storage, and reduced the loss of grain mildew and insect damage. In the grain sto...
