Embodiment

[0024] The invention includes the acquisition of the current state quantity of the orchard management machine, the calculation of the overturn judgment index and the anti-overturn early warning strategy. The calculation of the tipping judgment index uses STM32 single-chip microcomputer, the speed sensor uses Saimo PLR2300 speed rotary encoder, the inclination sensor needs to use MTI-300 inclination sensor, the acceleration sensor uses MPU6050 acceleration sensor, the pressure sensor uses FSR402 resistive film pressure sensor, and STM32 single-chip microcomputer Obtain the walking speed of the orchard management machine and detect the inclination angle of the orchard management machine in real time. The STM32 single-chip microcomputer uses the inclination sensor and the acceleration sensor to collect the current inclination angle of the orchard management machine, the initial angular velocity of the orchard management machine, and the roll acceleration of the orchard management m...

Abstract

The invention relates to a rollover early-warning control system and control method for an orchard management machine. The rollover early-warning control system comprises a platform detection module, a rollover judgment control module and a rollover prevention early-warning module, wherein the platform detection module comprises a speed sensor, a tilt angle sensor, an acceleration sensor and a pressure sensor; the rollover judgment control module is a single chip microcomputer; the single chip microcomputer is connected with the speed sensor, the tilt angle sensor, and the acceleration sensor and the pressure sensor respectively. The control method specifically comprises: acquiring a current quantity of state of the orchard management machine, calculating rollover judgment indexes, and carrying out a rollover prevention early-warning strategy, wherein the rollover judgment indexes adopt a rollover early-warning time and a carload transverse load transfer rate. According to the invention, the rollover early-warning time and the carload transverse load transfer rate are set as the rollover judgment indexes at the same time, so that the rollover early-warning control system realizes active early-warning, and active braking or active steering of the orchard management machine is realized for a possible rollover state, thereby realizing double rollover prevention measures and ensuring that the orchard management machine is safer and more reliable.

Description

technical field [0001] The invention relates to an overturning early warning control system and control method for an orchard management machine, in particular to an overturning early warning control for an orchard management machine in hilly and mountainous areas. Background technique [0002] my country has a vast territory and a large area of ​​fruit tree planting. The terrain of orchards is diverse. Hilly and mountainous areas are the main areas for orchard planting. The plots are uneven and undulating. Orchard management machines play an important role in orchard operation machinery. From fruit tree pruning to fruit picking to transportation operations, the management platform plays play an irreplaceable role. Facing the orchard planting mode with complex terrain and slopes, the existing orchard management machines are not very versatile, have poor tipping stability performance, and lack corresponding safety warning measures. The adaptability of the machine is of grea...
