Development of an electronic device for protection from agricultural machinery hazards

Abstract

Objective: The objective of this study was to develop an electronic device capable of being connected to agricultural machinery to protect operators from mechanical hazards. Material and Methods: The electronic device contains two electronic circuits for alarming and automatically shutting off. The device is equipped with a pair of passive infrared sensors with a daylight resistance to increase the devise sensitivity. The alarm circuit operates a siren that warns the operator when approaching dangerous objects such as rotors, knives, exposed gears, etc. The automatic disconnect circuit turns off the tractor's engine when the operator does not pay attention to the alarm. Four sensing distances of 0.25, 0.5, 0.75, and 1.00 m were tested with three delay periods of 30, 60, and 90 s at two levels for the interstitial distances between the sensors of 150 and 200 mm. Results: The device was tested by simulating human hands to test the efficiency of the sensor response and the efficiency of the time delay. The addition of the day light resistance to the passive infrared sensor led to an increase in its response efficiency, from 90.67% to 95.83%. Conclusion: The developed electronic device can be attached to agricultural equipment to protect operators from operating risks.

Tarım makineleri tehlikelerinden korunmak için bir elektronik cihazın geliştirilmesi

Öz

Amaç: Bu çalışma, operatörleri mekanik tehlikelerden korumak için tarım makinelerine bağlanabilen bir elektronik cihaz geliştirmeyi amaçlamaktadır. Materyal ve Yöntem: Elektronik cihaz, alarm vermek ve otomatik olarak kapatmak için iki elektronik devre içermektedir. Cihaz, cihaz hassasiyetini artırmak için gün ışığı direncine sahip bir çift pasif kızılötesi sensörle donatılmıştır. Alarm devresi rotorlar, bıçaklar, açıktaki dişliler vb. gibi tehlikeli nesnelere yaklaştığında operatörü uyaran bir siren çalıştırır. Otomatik bağlantı kesme devresi, operatör alarma dikkat etmediğinde traktörün motorunu kapatır. 0.25, 0.5, 0.75 ve 1.00 m'lik dört algılama mesafesi, 150 ve 200 mm'lik sensörler arasındaki boşluk mesafeleri için iki seviyede 30, 60 ve 90 s'lik üç gecikme periyoduyla test edildi. Araştırma Bulguları: Cihaz, sensör yanıtının etkinliğini ve zaman gecikmesinin etkinliğini test etmek için insan elini simüle ederek test edildi. Pasif kızılötesi sensöre gün ışığı direncinin eklenmesi, tepki veriminde %90,67'den %95,83'e bir artışa yol açtı. Sonuç: Geliştirilen elektronik cihaz, operatörleri işletme risklerinden korumak için tarım ekipmanlarına takılabilir.
