Abstract

The invention discloses a cereal drying control system which is characterized in that a human-computer interface, a single chip microcomputer, a sensor and a PLC module are included, the human-computer interface and the sensor are connected with the single chip microcomputer, the sensor comprises a material position sensor, a moisture sensor and a temperature-humidity sensor, the PLC module is connected with the single chip microcomputer, a grain discharging motor, a fan, a feeding lifter, a discharging lifting and an electromagnetic relay, and the electromagnetic relay is connected with a boiler. Compared with the prior art, the cereal drying control system has the advantages of being stable, reliable, economical and flexible, the parts such as the single chip microcomputer, the PLC module and the sensors are matched, and cereal drying intelligent drying is achieved.

Description

technical field [0001] The invention relates to a grain drying control system. Background technique [0002] The grain dryer can reduce the moisture contained in the grain in time, reduce the loss of grain mildew, ensure the quality of the grain, increase the yield of grain, reduce the labor intensity of farmers, and then increase the income of farmers. It plays an important role in the storage and quality assurance of grain. [0003] At present, in the development and application field of domestic grain drying equipment control systems, the grain moisture measurement is generally separated from the grain drying equipment temperature control system, that is, the grain moisture is measured off-line, and the equipment temperature control is manually adjusted. It is difficult to realize online control of temperature and moisture, and it is rare to integrate the two into one system. It is still at a relatively low level in terms of control accuracy and intelligent control, and r...
