Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking-out device used at a construction site or the like.

[0002]

2. Description of the Related Art Conventionally, a device such as a total station, a theodolite or a level is used to measure the distance and angle from a reference point to determine the marking point, and to determine the marking point. Between the ejection points, the thread with the black ink in it is stretched out from the so-called urn, and is repelled by hand on the floor or wall with tension applied to the thread. Then, a line is drawn on the floor or the like by the ink attached to the thread.

[0003]

In order to determine the marking point in this way, the total station, theodolite,
Since a device such as a level is used, a minimum of one technician who handles the device and one other assistant are required to measure the distance and angle, and it is a laborious and troublesome task that requires two people to work together. Met.

An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to provide a marking-out device which can determine the marking-out point easily and accurately by one person.

[0005]

In order to achieve the above-mentioned object, the present invention is a total station which is equipped with photographing means, and which is connected with an input means for setting a marking point and an image transmitting means for transmitting an image of the photographing means. And a display screen worn by an operator to receive an image from the image transmission means and display a marking point, and the total station is equipped with a light emitting means for indicating the marking point. It is a summary.

[0006]

According to the present invention, the total station is automatically oriented in the direction of the marking point preset by the input means, and the photographing means such as the CCD camera catches the marking point. The image is displayed from the image transmission means on the display screen worn by the worker. Therefore, the operator marks the marking point while looking at this display screen.

According to the second aspect of the present invention, in addition to the above action, a laser beam or the like is emitted from the light emitting means toward a rough position of the marking point, so that the operator can find the position of the marking point. It will be easier.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing an embodiment of the marking-out device of the present invention. The marking-out device of the present invention comprises, as a basic configuration, a total station 1 and a small liquid crystal television 2 which is a display screen carried by an operator.

The total station 1 is equipped with, for example, a CCD camera 3 as a photographing means, and a control device 4 and a CC using a personal computer or the like as an input means for setting a marking point.
The image transmission device 5 that transmits the image captured by the D camera 3 is connected. Further, a laser light emitter 6 as a light emitting means for irradiating the approximate position of the marking point is mounted on the total station 1.

Then, the coordinates of the marking point are input in advance to the front control device 4 as the intersections of the X axis and the Y axis, and the marking point is set.

The liquid crystal television 2 carried by the operator is formed to have a size that can be mounted on one eye, and the operator receives signals from the ink jet pen 8 and the image transmission device 5 in addition to the liquid crystal television 2. An image transmission device 9 for receiving and outputting to the liquid crystal television 2 is carried.

As described above, in order to strike on the marking point, the total station 1 is installed at an arbitrary position on the site, and the reference positions are set at two points to set the total station 1 on the site. Check the coordinates.

Based on the confirmed coordinates of the present position, the coordinates of the marking points set in the control device 4 are read out to the total station 1, and the total station 1 automatically faces in the direction of the coordinates of the marking points. Then, a laser beam is emitted from the laser emitting device 6 in the direction of the marking point to indicate the approximate position of the marking point.

The operator knows the approximate position of the marking point by looking at the position designated by the laser beam. CC at the same time
The D camera 3 photographs the location of the marking point, and the image is transmitted by the image transmission device 5 to the liquid crystal television 2 carried by the worker.
As shown in FIG. 2, on the display screen 7, a video image of the location of the marking point is displayed as a composite image with the marking point 10 represented by, for example, a mark at the intersection of the X axis and the Y axis.

While looking at the image on the display screen 7 with one eye, the operator positions the marking pen 8 at the marking point with the help of the laser beam with the other eye, and displays it on the display screen 7. The tip of the ink-writing pen 8 is made to coincide with the position of the ink-printing point 10 displayed in coordinates, and ink is printed here.
When the black ink is finished, an end signal is transmitted to the total station 1 from the portable image transmission device 9.

Then, the other blacking point is displayed on the display screen 7 in the same manner as described above, and blackening is performed by the same operation.

[0017]

As described above, the marking-out device according to the present invention enables one operator to easily and accurately mark a mark and improve workability.
