DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

Hereinafter, the technical structure of the present invention will be described in detail with reference to the preferred embodiments.

The waveguide distributor of the inspection terminal of the disaster communication construction facility network of the present invention can easily grasp the disconnection point by forming the distributor as a waveguide and constructing the inspection terminal at each part branched to the input and output of the waveguide.

A distributor is generally used in a relay network. The distributor divides a single signal into a plurality of signals, and outputs the signals to distribute and transmit signals to a plurality of devices.

FIG. 1 is an internal configuration diagram showing a configuration of a waveguide distributor of a disaster terminal of the present invention.

1, the waveguide distributor 1 of the disaster communication construction facility network detection terminal of the present invention includes a case 110 having a predetermined size, and an input transmission path 30 connected to one side of the case 110 And two or more output terminals 130 connected to the output transmission path 40 are formed on the other side.

One input terminal 120 is formed on one side of the case 110 and two or more output terminals 130 are formed so that a signal inputted to the input terminal 120 is branched to each output terminal 130 do.

The input terminal 120 is connected to the input transmission path 30 to receive the input signal, and the output terminal 130 is connected to each output transmission path 40 to transmit the output signal.

In the present invention, the detection terminal 140 may be formed on one side of each of the input terminal 120 and the output terminal 130 of the case 110 to determine whether the intensity input through the waveguide distributor is normal, So that it is possible to easily determine whether the intensity of the output signal is normal.

A waveguide body 160 formed as a waveguide is formed in the case 110 so that a signal received from the input terminal 120 is distributed to the respective output terminals 130 in the case 110 do.

As described above, in the present invention, in order to overcome the dielectric loss of the coaxial line, a waveguide in which an insulator is air and a center conductor which is a cause of conductor loss is removed is used as a transmission line.

In addition, the waveguide (waveguide) is a microwave transmission line made of a hollow metal tube, and its cross section is square and circular. In microwave, waveguides have much fewer losses (resistive, radiative, and dielectric) than parallel two-wire or coaxial cables and can deliver much greater power than coaxial cables of the same dimensions. A waveguide is a kind of high-pass filter, and the mode in the tube has a constant cut-off wavelength and does not pass the wave of longer wavelength. In addition, in the tube, it propagates to a wavelength different from that of the excitation wavelength.

The waveguide main body 160 is formed of a waveguide as a whole and includes an input part 161 having one end connected to the input terminal 120 and two or more output parts 130 branched at the other end of the input part 161 And an output unit 162 connected to the input terminal 120 to divide the signal received from the input terminal 120 and output the divided signal to the output terminal 130.

The inspection hole 163 of the main body 160 is made to pass through one or more holes as needed to adjust the coupling amount and the mode.

When a plurality of detection holes 163 are formed, it is preferable that the detection holes 163 are formed in regular shapes and intervals.

The electric wave power signal inputted to the input terminal 120 is divided and output to the two or more output terminals 130 uniformly and unequally through the waveguide body 160 formed by the waveguide.

At this time, the shape of the waveguide constituting the waveguide body 160 may be formed to have various cross-sections such as a quadrangle, a circle, and an ellipse.

FIG. 2 is a partially cutaway perspective view of a connection portion between a wave guide body and a test tube, which is a portion 'A' in FIG. 1; FIG.

An input detecting tube 170a is formed in the input part 161 of the wave guide body 160 connected to the input terminal 120 to detect whether the intensity of the radio wave power inputted to the input terminal 120 is normal. It is possible to form the input test tube 170a by overlapping or attaching the waveguide to the upper portion, the lower portion, or the side surface of the input portion 161 and regularly drilling the inspection hole 163 of one (1 EA) have.

At this time, the input electric wave power intensity can be transmitted to the output, and the detection holes 163 having various shapes can be formed in various dimensions and intervals so as to extract only a small amount of signal strength so that only the detection can be performed. The size of the waveguide forming the waveguide 170a can be adjusted.

An output measuring tube 170b is formed at the output part 162 of the waveguide body 160 connected to the output terminal 130 to detect whether the intensity of the electric wave output to the output terminal 130 is normal, And is formed in the same manner as the detecting tube 170a.

3 is a comparative diagram of a conventional distributor and a distributor application embodiment of the national disaster safety communication network of the present invention.

As shown in FIG. 3A, when the radio wave service is not output to the antenna 5 in the related art, it is possible to use any one of the failure occurrence sections connected to the inside of the distribution paper sheet 6, before or after the distributor 6 or through cables, connectors, distributors, It is not possible to confirm whether or not a fault has occurred in the waveguide distributor 1 and it is necessary to confirm the fault only by the naked eye. However, when the waveguide distributor 1 of the present invention is applied, It is possible to check whether the intensity inputted through the waveguide distributor 1 is normal or the signal intensity outputted through the waveguide splitter is normal can be easily, quickly, and accurately tested without releasing the waterproof connector.

As described above, in order to overcome the dielectric loss of the coaxial line, the waveguide distributor of the inspection terminal of the disaster communication construction facility network of the present invention uses an insulator as air and uses a waveguide which eliminates the center conductor which is a cause of conductor loss as a transmission line It is possible to easily determine whether the intensity of the power inputted through the waveguide splitter is normal and whether the intensity of the signal outputted through the waveguide splitter is normal, In the infrastructure, it is very beneficial to be able to accurately identify the fault occurrence period for the passive elements, and to check the advantages and promptness of the rapid A / S so that it can be directly connected with the prevention of disaster safety in the national disaster safety communication network.
