Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of erroneous operations of a crane due to human's error when a HMD(head mounted display) is used, and assure safety around the crane. SOLUTION: The interlock device is formed out of a three-dimensional camera loaded on a crane, a three-dimensional image display device HMD 3 which is mounted over the head of an operator in an operating room, a mount detector 4 detecting that the HMD 3 is mounted over the operator's head, a transmission detecting device 5 detecting that three-dimensional images are transmitted to the HMD 3, and of an interlock controller 6 which transmits each interlocking signal restricting the turning angle or traveling operation of the crane while it is aware through the mount detector and the transmission detecting device that the operator is watching the three-dimensional images.

Next, the operation will be described. The driver of the hoist 2 works while looking at the image of the stereoscopic camera 1 with the HMD 3 for the work that cannot be seen with the naked eye. At that time, since the area other than the field of view of the stereoscopic camera 1 cannot be seen, it is dangerous to move the hoist 2 to an invisible range, which may cause an unexpected collision accident, and the hoist is likely to malfunction due to a human error. The wearing detector 4 detects whether or not the driver wears the HMD 3, and the transmission detector 5 detects whether or not the HMD 3 receives the video signal of the stereoscopic camera 1 by detecting the presence or absence of the signal. , The interlock controller 6 confirms both signals by AND processing, etc., and when both the mounting detector 4 and the transmission detector 5 are ON, an interlock signal is sent to the control unit (not shown) of the hoist. When the interlock signal is received, the control unit controls the driving force to regulate the turning operation angle of the hoisting machine 2 within the view angle range of the stereoscopic camera 1 and prohibit the forward and backward movement of the hoisting machine body. To.

When the attachment detector 4 is OFF and the transmission detector 5 is ON, the stereoscopic camera 1 is photographing, but the driver side does not wear the HMD 3, so that the stereoscopic camera 1 If you are not working with images and the attachment detector 4 is ON but the transmission detector 5 is OFF,
When the HMD3 is placed on the head, but there is no image yet, it looks like the front is seen with the naked eye, and when both the mounting detector 4 and the transmission detector 5 are turned on.
In the case of FF, it is determined that the operation is not performed by looking at the image of the stereoscopic camera 1, and the hoist 2 is not regulated.
