현대에 있어 전기는 사람들에게 없어서는 안될 중요한 자원 중에 하나인데, 이러한 전기는 사람들이 생활하는데 필요한 여러 가지 가전제품 또는 기계 등이 동작하도록 하는 동력원이 되어 매우 유용하게 사용되기도 하지만, 전기에 사람이 감전되면 생명을 잃게되는 등 사람에게 치명적인 상해를 입히기도 한다.In modern times, electricity is one of the indispensable resources for people, and it is very useful because it is the power source for various household appliances or machines that people need to live, but when people get electric shock It can also cause fatal injuries, including loss of life.
일반적으로 고가형 건설장비의 탑재차량은 이동중에 활선에 접촉할 수 있으며, 활선 근접작업시 고가형 건설장비의 활선 접촉 우려가 크기 때문에 감전 위험이 높은 문제점이 있으며, 또한 현재 산업현장에서 사용하고 있는 활선접근 경보기는 주로 안전모에 부착하는 활선작업자에 대한 대인용으로서 근접거리가 작아지면 경보가 울리도록 설계되어 왔으나, 차량에 직접 경보기를 부착하는 경우는 없어 인체의 활선접촉 이외의 장비의 직접적인 접촉의 경우나, 차량에서 운전자가 크레인을 조작하는 경우나, 차량의 이동중에 운전자의 시각에만 의존하여 접근여부를 확인할 수 있어서, 항상 활선의 접촉 위험에 노출되어 있는 실정이다.In general, a vehicle equipped with high-priced construction equipment may come into contact with live lines while moving, and there is a high risk of electric shock due to the high risk of live contact with high-priced construction equipment when working near a live ship, and also the live access that is currently used in industrial sites. The alarm is mainly for the live worker who attaches to the hard hat. The alarm has been designed to sound when the proximity distance becomes small. However, the alarm is not attached directly to the vehicle. In the vehicle, when the driver operates the crane or when the vehicle is moving, it is possible to check whether the vehicle is approaching only depending on the driver's sight, and thus the vehicle is always exposed to the risk of live contact.
