OHT Method for controlling junction position transport of overhead hoist transport carriage

The present invention relates to a method of determining the operation of an OHT vehicle in a junction section and comprises the steps of: requesting entry permission to enter the joint suction from the OHT vehicle scheduled to enter the junction section; checking whether there is entry permission and whether there is an OHT vehicle that has entered the junction section; allowing the OHT vehicle that has requested entry permission to enter and pass the junction section if there is an entry permission and no OHT vehicle has entered the junction section; switching to no entry and making the OHT vehicle that requested entry permission wait if there is entry permission and there is an OHT vehicle that has entered the junction section; and switching to entry allowed so that the OHT vehicle enters the junction section if there is no entry permission and no OHT vehicle has entered the junction section. Accordingly, the productivity of logistics transportation can be improved. 본 발명은 OHT 반송차의 합류구간 운행 결정 방법에 관한 것으로, 합류구간으로 진입할 예정인 OHT 반송차에서 합류구간으로 진입하기 위한 진입허가를 요청하는 단계와, 진입허가가 있는지 여부와 합류구간으로 진입한 OHT 반송차가 있는지 여부를 확인하는 단계와, 진입허가가 있고 합류구간으로 진입한 OHT 반송차가 없으면 진입허가를 요청한 OHT 반송차를 합류구간으로 진입하여 통과시키는 단계와, 진입허가가 있고 합류구간으로 진입한 OHT 반송차가 있으면 진입불가로 전환하여 진입허가를 요청한 OHT 반송차를 대기시키는 단계와, 진입허가가 없고 합류구간으로 진입한 OHT 반송차가 없으면 OHT 반송차가 합류구간으로 진입하게 진입가능으로 전환하는 단계를 포함하는 것을 특징으로 한다.
