## Abstract

A detection system includes a plurality of support posts, cables supported by the support posts, a winding device operable to wind the cable, a lifting and lowering device that is connected to the cable, and is movable in an air when the cable is wound by the winding device, and a detecting device hung by the lifting and lowering device. The detecting device is configured to be moved by the winding device in a region defined by the support posts, and lowered by the lifting and lowering device to detect information concerning an object.

## Claims

### Claim 1

A detection system comprising:
a plurality of support posts;
a cable supported by the support posts;
a winding device operable to wind the cable;
a lifting and lowering device that is connected to the cable, and is movable in an air when the cable is wound by the winding device; and
a detecting device hung by the lifting and lowering device, wherein
the detecting device is configured to be moved by the winding device in a region defined by the support posts, and configured to be lowered by the lifting and lowering device to detect information concerning an object.

### Claim 2 (depends on 1)

The detection system according to claim 1, wherein the detecting device is lowered by the lifting and lowering device and detects information concerning a root side of a tree in a forest.

### Claim 3 (depends on 2)

The detection system according to claim 2, further comprising a processing device configured to analyze data obtained by detecting, from the air, a plurality of trees present in the region defined by the support posts, and determine a position among the trees, as a detection point at which the detecting device is lowered.

### Claim 4

A detecting method comprising:
a first step of moving a lifting and lowering device to a point above a detection point, by winding a cable by a winding device operable to wind the cable supported by support posts, the lifting and lowering device being connected to the cable and being movable in an air when the cable being wound by the winding device;
a second step of lowering a detecting device by the lifting and lowering device, the detecting device being hung by the lifting and lowering device;
a third step of detecting information concerning an object, by the detecting device; and
a fourth step of lifting the detecting device by the lifting and lowering device, wherein
the first step through the fourth step are repeated at another detection point.
