DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying device, and more particularly to a surveying device capable of easily guiding a worker having a target to a target surveying point.

[0002]

2. Description of the Related Art Conventionally, pile driving work (measuring) at a construction site or the like.
When performing the above, it is necessary to accurately position the place where the pile is driven, and a total station capable of distance measurement and angle measurement has been used as a surveying device to be used. This positioning operation requires at least two workers, one on the total station side and one on the target side.

[0003] Then, the worker on the total station side needs to guide the worker on the target side to the positioning point.

The guidance to the positioning point is performed by collimating the direction to the measuring point calculated by the total station, and moving the corner cube formed on the target in the collimating line direction in order to measure the distance. Was realized.

That is, the operator of the total station confirms the difference between the calculated direction angle and distance and the actual measured direction angle and measured distance on the display of the total station, and uses a transceiver or the like to check the difference between the target side and the target. Was instructed on the moving direction and the moving distance.

[0006] Further, the worker on the target side moves the target based on the instructions of the moving direction and the moving distance transmitted from the worker on the total station side by using a transceiver or the like, and arranges the target at a precise position. I had to drive a stake.

[0007]

However, the conventional guide to the positioning point has a problem that both the total station side and the target side operators have to carry the transceiver, which is troublesome.

[0008] Further, since communication between transceivers needs to be performed while confirming the transmission / reception status of each other, it takes time,
There was a problem that work efficiency was reduced.

[0009] In the case of communication using wireless voice, there have been problems such as that the instruction method on the total station side differs depending on the operator, and it is difficult to hear due to noise due to interference or external electromagnetic noise.

When optical communication is used, it is necessary to provide a light receiving device on the target side, and the data communication of the mounting position and the position information and the like increases the cost of the communication device.
There was a problem that it was uneconomical.
