Abstract
A crane control based on quoted location data and observed ambient data provided by at least one identifier, the goods to be conveyed by the crane can be controlled to the location site. The identifier takes pictures of at least two difference areas, which is implemented so that the identifier is pivotable, or fixed, whereby the certain image area directed to the identifier is reflected from a reflecting surface.
Claims16
A method for conveying a load between two location sites, at one of which sites the load is gripped for transfer, and at the other of which sites the load is discharged, said method comprising the steps of:
- selecting a load to be gripped;
- attaching at least one grip member to the load;
- observing a first reference point adjacent the load, at least with identification means that is disposed on the grip member and operably connected to a control system to record information on the first reference point received from the identification means;
- transferring the load toward the other location site, the other location site being defined by a second reference point adjacent the other location site that is identifiable by the identification means using information stored in the control system on the second reference point;
- providing current information by observation with the identification means at specified intervals during conveyance of the load for use by the control system;
- and
- comparing the stored information on the second reference point to the current information provided by the identification means during conveyance of the load to identify the second reference point, and to control the conveying of the load to the other location site.
A method for conveying a load between two location sites, at one of which sites the load is gripped for transfer, and at the other of which sites the load is discharged, said method comprising the steps of:
- selecting a load to be gripped;
- attaching at least one grip member to the load;
- observing a first reference point adjacent the load with at least one video camera that is disposed on the grip member and operably connected to a load control system to record information on the reference point received from the identification means;
- transferring the load to the other location site, the other location site being defined by a second reference point adjacent the other location site as identified by the at least one video camera by taking a first picture of the other location site with the camera;
- storing the picture into a computer memory and control system operably connected to the camera;
- determining in the first picture a digital image area to be searched;
- taking a second picture of the other location site with the camera;
- and
- comparing the digital image area of the second picture with the digital image area of the first picture to determine the relative transit distance from the position where the first picture was taken.
