Development of Ground Based Multi-Source Information Collection System by Converting Paddy Transplanter

Abstract

Precision agriculture has created a technology revolution in production agriculture and it requires reliable technology to acquire accurate information on crop conditions. A ground-based integrated sensor and instrumentation system was developed to measure real-time crop conditions. The integration system included multispectral camera and N-sensor for real time Nitrogen application. The system was interfaced with a DGPS receiver to provide spatial coordinates for sensor readings. Before mounting of the sensors on modified paddy transplanter, different mountings and frames were attached with the paddy vehicle to mount the sensors, camera and power source. Battery mounting plate was required to fit imported 12 V & 80 A battery on vehicle. New bracket had fabricated to suit the new battery and it can be adjusted vertically 25~30 mm as per the requirement. For overturning balancing of rice transplanter extra weights of 100 kg were added at the rear of the rice transplanter. Trails were done in puddle rice field. By adding additional weight, there was no problem of over turning in the field in normal operations. The results showed that the integration sensor and instrumentation system supports multi-source information acquisition and management in the farming field except high clearance of tractor.

Precizna poljoprivreda je dovela do tehnološke revolucije u poljoprivrednoj proizvodnji, koja zahteva pouzdanu tehnologiju za sakupljanje tačnih informacija o stanju useva. Zemaljski integrisani senzor i sistem instrumenata su razvijeni za određivanje stanja useva u realnom vremenu. Ovaj integrisani sistem je uključio multispektralnu kameru i N senzor za primenu azota u realnom vremenu. Sistem je povezan sa DGPS prijemnikom za određivanje prostornih koordinata očitavanja senzora. Pre postavljanja senzora na modifikovanu sadilicu postavljeni su razni sklopovi i ramovi koji nose senzore, kameru i izvor napajanja. Napajanje je obezbeđeno sa akumulatorske baterije na vozilu, 12V-80A. Za obezbeđenje vozila od prevrtanja postavljeni su dodatni tegovi od 100 kg na zadnju stranu.
