Embodiment Construction

[0016] As shown in Fig. 1, the inter-plant electric drive weeding control system is composed of the knife and seedling distance information acquisition module, the speed information acquisition module, the motion execution unit and the motor angle return module. The knife-seedling distance information acquisition module uses the camera to dynamically obtain the field seedling grass image in real time and input it to the PC for image processing to obtain the knife-seedling distance information. The speed information acquisition module measures the forward speed in real time through the rotary encoder installed on the speed measuring ground wheel shaft. The operation execution unit is composed of a driver and a motor, and the motor drives the disc hoe to move. This design involves the control of three mutually independent operation execution units. The motor angle return module adopts Hall sensor signal to input corresponding driver and makes the motor angle return to zero. Th...

Abstract

The invention provides an inter-plant electrically driven hoeing control system for an electrically driven hoeing machine according to the demand for mechanical hoeing of a greenhouse. The system uses an MC9S12XDG128 double-core single chip microcomputer as a hardware core, and integrates real-time signal input of a Hall sensor and a rotary encoder, visual information, received in real time, of an upper computer (PC) is interrupted through an RS232 serial port, real-time communication with a lower computer (electric motor driver) is performed by adopting a CAN bus, the rotating speed and a rotating angle of a disc hoe knife are controlled in real time, and accordingly inter-plant hoeing and seedling avoidance are achieved. A hoeing test result in the greenhouse indicates that the advancing speed is 1.2 km/h, and the seedling damage rate is lower than 10%.

Description

technical field [0001] The invention relates to a control system, in particular to an inter-row electric drive weeding control system. Background technique [0002] Traditional weeding methods include manual weeding and chemical weeding. Manual weeding is labor-intensive, time-consuming and labor-intensive, and has low operating efficiency; chemical weeding is likely to cause environmental pollution and pesticide residues in agricultural products, thereby affecting the sustainable development of agricultural production and human diet health. Therefore, field mechanical weeding has important research significance and broad application prospects. [0003] According to the growth position of weeds in the field relative to crops, mechanical weeding can be divided into inter-row weeding and inter-row weeding. Common intertillage and weeding are mostly inter-row weeding, but inter-row weeding is the current research difficulty and hotspot. Wei Zhaokai etc. designed a kind of we...
