Intelligent broadcast sowing control system

Abstract

The invention provides an intelligent broadcast sowing control system. A touch screen and control keys are installed on a control box, and a radiator is installed on one side of the control box; the control keys are a power key, a start key, a pause key and a stop key; a PLC (Programmable Logic Controller) is installed in the control box, one end of the PLC is connected with the start key, the pause key, the stop key, a sensor 1 and sensors 2 respectively, and the other end of the PLC is connected with a contactor, the touch screen, a motor driver and a buzzer respectively; the contactor is connected to a high voltage fan, the driver is connected to a step motor, the PLC is connected to a booster and connected with the power key, the sensor 1 is arranged on a feed box, and the sensors 2 are arranged on a broadcast sower and a broadcast sower ground wheel. The intelligent broadcast sowing control system can automatically control the rotating speed of a motor according to the running speed of a tractor, thereby keeping the broadcast sowing quantity within unit area unchangeable, and realizing a series of intelligent broadcast sowing control such as automatic variable accurate broadcast sowing, reversing stop, empty box alarm and the like.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an intelligent sowing control system. Background technique [0002] At present, domestic fertilizers and seeders use the speed control knob to control the speed of the DC gear motor to change the feeding speed of the fertilizer applicator or seeder discharge wheel, so as to achieve the purpose of flexibly controlling the spreading amount. This control method can change the amount of sowing according to different needs, but it cannot accurately control the amount of sowing, reduce waste, save the cost of seeds and fertilizers, and give an alarm for empty boxes. For example, when working, you can only estimate the approximate position of the knob, and estimate the discharge speed to control the spreading value; moreover, when the tractor is changing gears or reversing, the discharge speed cannot be changed according to the tractor’s driving speed. Keep the spread rate pe...
