Hereinafter, the installation and use method and the alignment method of the laser transmitter according to the present invention will be described in detail.

First, the operator prepares two or more laser transmitters and then specifies a position to communicate with each other. Experimental results show that the laser transmitter according to the present invention is typically guaranteed an effective transmission distance of 4 to 5 km.

Referring to FIGS. 8 and 9 and the above-mentioned drawings, the operator is at each of the corresponding points, for example, the first point OP1 and the second point 0P2, which are not limited but are preferable installation positions such as the summit of a building or a mountain. Install each support (P). Then, the mounting plate (M) is fixed to each support (P) to mount the laser transmitter. In more detail, the mounting member 94 provided on the lower portion of the lower member 80 of the support device 72 mounted on the main body 10 of the laser transmitter has a shaft 96 provided at the center thereof. Mounting plate (M) rotatably fixed to the support (P). Thereafter, the operator rotates the entire support device 72 or the mounting member 94 to adjust the azimuth angle so that each laser transmitter installed at each point faces each other, and then uses the fixing member 98 composed of bolts and nuts. The mounting member 94 is fixed to the mounting plate (M). Of course, thereafter, the azimuth angle of the entire laser transmitter can be adjusted by releasing or tightening the mounting member in such a manner as to access and access the tool to the fixing hole 94a and the fastening hole Ma formed in the mounting member 94 and the mounting plate M. have.

As described above, after the laser transmitters are installed to each support P in a state in which the laser transmitters face each other, the operator again adjusts the up and down or the high and low angles of the main body 10 by using the support device 72. That is, by adjusting the upper member 78 in a swing or sliding manner with respect to the lower member 80 of the support device 72 to adjust the high and low angle of the laser transmitter itself or the main body 10. At this time, by the interaction between the convex lower surface 78a of the upper member 78 and the recessed upper surface 80a of the lower member 80, the upper member can slide smoothly, and also the upper member 78 Receiving groove 82 formed in the center of the guide is provided by the guide 84 provided in the central portion of the upper surface 82a of the lower member 80 is accurately guided by the high and low angle of the body 10 can be adjusted accurately and easily. .

Subsequently, when the high and low angles of the main body 10 are adjusted, the tool is inserted through the openings 90 formed at both sides of the upper member 78 to insert the nut 88c of the fastening device 88 into the lower member 80. The main body 10 is fixed by fastening to 88a. Of course, if necessary, the high and low angles of the main body 10 can be adjusted at any time by releasing and fastening the fastening device 88.

As such, in the state where the laser transmitter is installed to face each other at a predetermined distance, the alignment of the transmitting and receiving devices is adjusted for the actual transmission and reception of the laser light. That is, the left and right and the high and low angles of the respective transmitting apparatuses are adjusted so that the laser beam emitted from the transmitting apparatus of one laser transmitter accurately reaches the receiving apparatus of the counterpart laser transmitter while the main body of each laser transmitter is fixed.

In more detail, first, the alignment of the first transmitter 22 is adjusted using the first adjusting device 40 addressed to the first transmitter 22 constituting the transmitter 20 of one laser transmitter. do. That is, the azimuth and the high and low angles are adjusted by tightening or releasing the adjusting bolts 56 of the adjusting member 52 installed on the upper and side portions of the support plate 44 supporting the first transmitter 22. At this time, the first transmission port 22 is moved up and down or left and right with respect to the support frame 18 in response to the adjustment of the vertical movement or the horizontal movement of the support plate 44, and as a result, the alignment of the lens of the first transmission port 22 Is controlled.

Of course, being able to adjust the high and low angles and the azimuth angle of the first transmission tool 22 only by adjusting the upper and one side of the support plate 44 is the elastic force of each elastic member 50 supporting the support plate 44 and It can be achieved automatically by the support force of the adjustment bolt 56. This adjustment is also because the support plate 44 is arranged such that tension is exerted by each elastic member 50 to one of its corners. On the other hand, tightening and loosening of the adjustment bolt 56 as described above can be easily carried out by inserting a tool such as a driver through the through hole 16 formed in the cover 16, or the cover 16 is removed In the same manner as described in the adjustment bolt 56 can be adjusted.

After the alignment of the receiving lens of the receiver of the counterpart laser transmitter of the first transmitter 22 is completed, the second transmitter 24 is aligned to the receiver of the counterpart laser transmitter in the same manner. That is, the driver is inserted into the adjusting bolt 70 of the adjusting member 66 provided on the upper and side portions of the support plate 58 supporting the second transmitter 24 through the through hole 12a of the base 12. Tighten or release to adjust the azimuth and elevation angles. At this time, the second transmission port 24 is moved up and down or left and right with respect to the support frame 18 to correspond to the shank or left and right movement control of the support plate 58, as a result, the lens of the second transmission port 22 is a relative side It is aligned with the light receiving lens of the receiver of the laser transmitter.

Similarly, being able to adjust the high and low angles and azimuth angles of the second transmission tool 24 only by adjusting the upper and one side portions of the support plate 58 is the elastic force of each elastic member 64 supporting the support plate 58. It can be achieved automatically by the bearing force of the adjustment bolt (70). This adjustment is also because the support plate 58 is arranged by each elastic member 64 such that tension is exerted to one of its corners.

On the other hand, the other laser transmitter, that is, the counterpart laser transmitter can also align the transmitting port of the transmitting apparatus with respect to the receiving apparatus of one laser transmitter in the same manner as described above. Is omitted.

Of course, thereafter, by using a transmitter of the transmitter of one laser transmitter in a general manner by transmitting the laser beam to the light receiving lens of the other, that is, the receiver of the opposing laser transmitter, or vice versa It is possible to perform a predetermined laser communication.

As a result, as shown in FIG. 9, the laser beam emitted from each of the light emitting lenses 26A and 28A of one laser transmitter fixed to the first point OP1 is connected to the other point installed at the second point OP2. The laser beam emitted from each of the light emitting lenses 26B and 28B of one laser transmitter fixed to the light receiving lens 32B and fixed to the second point OP2 is installed at the first point OP1. The focus is focused on the other light receiving lens 32A. Accordingly, it is possible to quickly and accurately align each transmission port of the transmission device to each one laser transmitter to the reception device of the other laser transmitter, thereby achieving accurate communication with each other.

As a result, according to the alignment of the laser transmitter and the laser transmitter according to the present invention, it is possible to accurately and easily align each transmission port of the transmitting device to one laser transmitter to the receiving device of the other laser transmitter. It is possible to achieve accurate communication between each other has the effect of improving the productability and operability.

In addition, the laser transmitter according to the present invention can be manufactured in a compact and compact, easy to carry and install, there is an advantage that the workability and maintainability can be improved to perform a perfect waterproof and dustproof.
