Abstract

The invention discloses a grain drying system capable of achieving remote control. The grain drying system comprises a microprocessor control module. A grain humidity sensor, a three-phase SPWM wave output module and an upper computer are connected to the microprocessor control module. The three-phase SPWM wave output module is connected with a grain dryer. The microprocessor control module is connected with the upper computer through a RS485 communication module. An A / D converter is connected between the grain humidity sensor and the microprocessor control module. A grain temperature sensor, a hot air pressure sensor and a hot air temperature sensor are further connected to the microprocessor control module. The three-phase SPWM wave output module is further connected with a hot air furnace. According to the grain drying system capable of achieving remote control, remote control over the grain dryer and the hot air furnace can be achieved, and the automation degree of grain drying operation is further improved.

Description

technical field [0001] The invention relates to the technical field of process control, in particular to a grain drying system capable of realizing remote control. Background technique [0002] my country is the largest grain producer and consumer country in the world, but at present most of the grain drying still relies on the traditional natural drying method. Mildew, etc., have caused huge losses, so the use of grain dryers has become very necessary, but the existing grain dryers are mainly manual operations, with a low degree of automation, resulting in high energy consumption and low efficiency of the dryers. And the operation is inconvenient. [0003] my country's patent CN102679716A proposes a grain dryer capable of remote control, which can be remotely controlled through a host computer, so that the staff do not need to go to the scene to operate, and the working environment of the staff is improved. However, the technical solution according to this patent can only r...
