초록

고유가, 환경규제 등의 국제무역환경 변화에 따라 수출주력상품인 유압 브레이커의 고부가가치화를 위하여 지능형 전자제어유압시스템 분야인 ICT 융합기술을 활용하여 암반특성을 예측하고 최적모드(다단형)로 구동하는 지능형 파쇄기술 및 에너지 효율을 극대화할 수 있는 유압 브레이커 개발에 관한 연구를 수행하였다. 본 연구에서는 암반의 강도에 따라 최적의 타격력을 제공하기 위해 근접센서를 이용해 암반 타격 시 피스톤의 하강 깊이를 측정하고 이를 통해 암반의 특성을 판별하여 타격력을 결정하는 피스톤 스트로크의 길이를 솔레노이드 밸브를 이용해 제어하였다. 다단 타격시스템을 위해 컨트롤러와 디스플레이/조작장치를 개발하였고, 무선통신을 이용하여 상호 정보교환이 가능하도록 하였다. 최종적으로 암반 강도에 따라 3단으로 타격할 수 있는 제어시스템을 개발하였고, 실차실험을 통해 이를 검증하였다.

We have carried out the development for hydraulic breaker which can be operated by optimal mode with ICT convergence technology. This developed system can predict the rock properties. Moreover, this system can maximize the energy efficient with intelligent control of hydraulic system. In order to provide the optimal impact force, this system can measure the descending depth of piston with the proximity sensor and discriminate the rock properties with the measuring data and control the piston stroke using solenoid valve eventually. In addition, we have developed the controller, display module and operating device for cascade (multi-level impact) system and applied the module which can communicate each system by wireless communications. In conclusion, the control system which can control the multi-level impact in accordance with strength of rocks has been developed and approved by several field tests.
