Abstract

The invention relates to a magnetic navigation device of a greenhouse operation platform, which utilizes a magnetic sensor to obtain a yaw signal and belongs to the technical field of agricultural operation machines. The magnetic navigation device comprises magnetic nails, an I-shaped support, magnetic signal acquisition devices and a microprocessor, wherein the magnetic nails are arranged on the ground along a walking route of the operation platform, the I-shaped support is fixed on the operation platform, the magnetic signal acquisition devices are respectively fixed on a front arm and a rear arm of the I-shaped support, and the microprocessor is fixed on a connecting rod in the middle of the I-shaped support and responsible for receiving and processing signals acquired from the magnetic signal acquisition devices, emitting a corresponding implementation command to the operation platform according to the processing result and controlling the operation platform to walk normally. The magnetic navigation device has low cost, strong anti-interference capacity and high practicality, and can greatly save the labor cost.

Description

technical field [0001] The invention relates to a walking navigation device in the technical field of agricultural operation machinery, in particular to a magnetic navigation device for a greenhouse operation platform that uses a magnetic sensor to obtain yaw signals. Background technique [0002] The working space in the greenhouse is narrow. In order to avoid the crops from being crushed by the agricultural machinery, it is required that the agricultural machinery can walk along the designated route. However, due to the luxuriant branches and leaves in the middle and late stages of crop development, the line of sight is easily blocked when the machine is manually operated, and operations such as spraying pesticides are more harmful to the human body. Significance. More mature navigation methods mainly include laser navigation, ribbon navigation, GPS navigation, magnetic navigation and so on. Laser navigation and color ribbon navigation have high precision, but they also ...
