Description

[0001] The present invention relates to an underground precision geodetic system for geophysical mapping based on observation of underground facilities,

Field of the Invention The present invention relates to an underground precision geodetic system for geophysical mapping based on the observation of underground facilities in the field of geodetic surveying. More particularly, the present invention relates to a geodetic precision geodetic system for maintaining a transmit antenna and a receive antenna in a vertical direction, And observing the underground facilities to improve the efficiency of the electromagnetic wave radiated in the downward direction by maintaining the output impedance in the optimum state through the movement in the up and down direction and the downward direction even if the measurement position fluctuates due to the influence of the bent topography or the surrounding environment To a geotechnical geodetic system for geophysical mapping.

In general, underground facilities such as LNG supply pipelines, city gas pipelines, water supply and sewage pipes, power cables and telecommunication optical cables are buried in many places, and it is expected that buried underground facilities will be buried rapidly in the future.

These underground facilities are required to maintain and maintain the piping with stability and reliability in the state of construction and civil engineering works for construction, after-care, and repair.

In order to measure the underground burials, a radar system (Groung Penetrating Radar, GPR) is used.

As shown in FIG. 1, the radar apparatus for underground burial survey probes the depth of the underground buried object using a dual antenna with two horizontal antennas spaced apart from each other by a predetermined distance.

A dipole antenna, a bowtie antenna, a mixed-type antenna, etc. are used according to the frequency of an antenna used in a radar device for underground inspection, and when the impedance of the radiator is equal to the impedance of the antenna, the radiator emits a maximum amount of electromagnetic waves into the air. We make it together.

In general, the method of adjusting the impedance of the antenna is adjusted to be equal to the output impedance of the transmitter in the free space of the air, and when the impedance of the antenna is adjusted, the antenna is fixed to the fixture and operated optimally.

However, since the antenna has the characteristic that the impedance varies according to the surrounding conditions, the antenna that emits electromagnetic waves into the air can be obtained only by impedance matching to the free space in the air. However, in the case of the radar for underground penetration, The antenna is installed close to the surface of the ground.

When the antenna is installed on the ground surface, the impedance of the antenna varies according to the state of the ground, and the impedance of the antenna significantly deteriorates the performance of the antenna.

In addition, the conventional radar apparatus for underground buried probe has a problem that when the apparatus itself is inclined due to the influence of the bent topography or the surrounding environment, the impedance is fluctuated and the measurement can not be performed in an optimum state.

The data transmitter 109 is controlled by the control unit 140 and wirelessly transmits the ground geodetic data and the underground geodetic survey data measured by itself from the total station device 20 to the outside.

The vertical movement device 200 of the present invention includes a housing body 202 connected to the lower surface of the adjustment device 150, a cover plate 233 covering the housing body 202, A first guide groove 231 extending along a predetermined length in the vertical direction in the antenna body 230 and a first guide groove 231 spaced apart from the first guide groove 231 by a predetermined distance, Thereby forming a second guide groove 232 extending along a predetermined length.

The first guide groove 231 has a transmission antenna body 210 formed in a bar shape having a predetermined length in a vertical direction. The transmission antenna body 210 includes a transmission antenna 105 inside the lower end portion thereof, The first driver unit 212 is formed along the outer surface in the vertical direction.

The detachable gear 236 is fixed to one side of the antenna body 230 so that the first detachable gear portion 214 and the second detachable gear portion 224 formed at the lower end of the transmitting antenna body 210 and the receiving antenna body 220 are engaged with each other. Lt; / RTI >

A moving gear 235 meshes with one end of the first moving device unit and the second driving unit 222 and a removable gear 236 is attached to one end of the first removing gear unit 214 and the second removing gear unit 224. [ .

The controller 140 rotates the moving gear 235 when the antenna driving motor 240 is driven so that one of the transmitting antenna body 210 and the receiving antenna body 220 is lowered.

That is, when the transmitting antenna body 210 is lowered, the receiving antenna body 220 is raised.

This improves the efficiency of the electromagnetic waves radiated in the underground direction by changing the impedance of the antenna and making the antenna transmission and reception optimal.

When the transmission antenna body 210 is raised, the first detachment gear portion 214 of the transmission antenna body 210 is engaged with the detachment gear 236 to rotate the detachment gear 236.

The receiving antenna body 220 engaged with the removable gear 236 is lowered and the second driving unit 222 of the receiving antenna body 220 is engaged with the moving gear 235.

Since the moving gear 235 rotates in a direction to raise the transmitting antenna body 210, the receiving antenna body 220 in which the second driving unit 222 is engaged is lowered.

When the receiving antenna body 220 is lowered, the second detachable gear portion 224 of the receiving antenna body 220 is detached from the detachable gear 236.

The first driving gear portion 214 of the transmitting antenna body 210 is engaged with the removable gear 236 so that the first driving gear portion 212 of the transmitting antenna body 210 moves away from the moving gear 235.

Therefore, the moving gear 235 is engaged only with the second driving unit 222 of the receiving antenna body 220, and the detachable gear 236 is engaged with only the first detachable gear unit 214 of the transmitting antenna body 210.

The controller 140 can move only the receiving antenna body 220 having the second driving unit 222 engaged with the moving gear 235 rotated by the antenna driving motor 240 to a desired height.
