Description

Technical Field [0001] The present invention relates to a digital map update system,

The present invention relates to a system and method for updating a digital map of a digital terrain, and more particularly, to an apparatus and method for updating a digital map of a digital map, Using the drone, the drone is photographed periodically at low cost to compare the drone GPS location information in the shooting area with the actual location coordinates of the shooting area, so that the terrain change information is immediately reflected in the digital map to improve the accuracy of the digital map In the case of drone shooting, it is possible to reflect the river change information by collecting together the rainfall-related friendship report for each river and reflecting it on the numerical map, and furthermore, the module constituting the system can prevent the shortening of the lifespan due to heat deterioration. To the digital map update system of the changed feature through verification Will.

A digital map is a digital map that is obtained by analyzing various numerical information obtained by surveying maps, aerial photographs, and satellite images, and numerically editing the numerical information.

Therefore, the digital map must be accurately applied to the displayed topographical image so that the user can easily obtain the geographical / geographical information while viewing the map, and the drawn topographical image should be accurately applied to the geographical information It should be precisely shown, mainly used for various cadastral maps and topographical maps.

These digital maps are produced from the images collected through aerial photographing and ground photographing, and the collected images are completed with a complete image through a mutual connection between neighboring images, and are produced as a digital map.

However, in order to interconnect the collected images, a reference for accurate connection between images is required. In order to accurately capture the reference, it is necessary to take an accurate aerial image image and a ground image image according to the GPS coordinates.

That is, the aerial photographing and the ground photographing are accurately performed according to the GPS coordinates, and the accurate aerial image image and the ground image image are collected according to the GPS coordinates.

For this purpose, a reference point serving as a reference of photographing is required, and a device capable of externally displaying the reference point is also required.

Conventionally, various apparatuses have been proposed in which a camera receives a signal or light so that the position of the corresponding point can be recognized.

Conventionally, most of the conventional devices have a technology for allowing the camera to accurately receive and photograph light irradiated by itself, and in particular, there is no function of protecting itself from external pollution and managing itself, and thus the life of the device is short .

Of course, such a problem prevents the reference point performed by the apparatus from fully exercising, and thus it has been an urgent problem to be solved.

In addition, there has also been a disadvantage in that the modules constituting the system are accelerated to deteriorate due to heat, shortening the service life and shortening the maintenance period.

At this time, the double hand gun unit 4200 is installed on the upper frame FRM on which the door 2300 of the housing 2100 is installed.

The double-handed gun unit 4200 has a function of preventing the door from being rotated by closing the upper end of the door 2300 in addition to the basic locking function by the key holder (HOL) and the key (KEY) provided on the door 2300, .

This is because the worker often leaves the housing 2100 without accidentally locking the key, so that there is a high possibility that the unauthorized person may be cut, stolen, or exploited. Therefore, even if the key is not locked, The unit 4200 is always locked so as to block such a nuisance accident from the beginning.

An ID card reader 4300 is installed on the door frame DRF on which the door 2300 is installed and a unit controller 4210 is embedded on the upper side of the door frame DRF.

At this time, the unit controller 4210 has a built-in memory, and is configured to register an ID card for registration of an access permit person, which is a known technology, and thus a description thereof will be omitted.

The ID card reader 4300 is electrically connected to the unit controller 4210 so that the unit controller 4210 compares the ID information read by the ID card reader 4300 and determines whether the ID information is a permissible person .

The ID card reader 4300 is also disposed inside the housing 2100 so that the door 2300 can be closed while the worker enters the inside of the housing 2100 so that the door 2300 can be opened also inside the housing 2100. [ ) Is particularly preferable.

In addition, when the door 2300 needs to be opened quickly due to an emergency such as a fire, the emergency switch 4400 is operated to turn off the power supplied to the dual-purpose gun unit 4200, The emergency switch 4400 is installed on the upper frame FRM at the upper end of the front surface of the housing 2100 so as to be invisible and is closed by the cover so that the general person does not know that it is the emergency switch 4400 do.

Meanwhile, the dual-purpose gun unit 4200 includes a locking plate 4220, as shown in FIG.

At this time, the locking plate 4220 is opened and closed in accordance with a control signal of the unit controller 4210 as a blocking plate for preventing door opening.

In addition, it is preferable that the double-vision gun unit 4200 is covered so that the external appearance is not exposed through a separate cover.

5% by weight of 1-chloro-2,3-epoxypropane, 5% by weight of methyltrimethoxysilane, 10% by weight of polyvinyl alcohol, silicone resin 10% by weight, triethanolamine 2.5% by weight, petrolatum 1.5% by weight, and the rest of the polycarbonate resin.

Here, 1-chloro-2,3-epoxypropane is added as a chlorine-based material having a high reactivity for stabilizing the reaction of the composition, and methyltrimethoxysilane is improved in durability by strengthening the bonding force between emulsified materials by hydrophobicity .

In addition, polyvinyl alcohol is added to enhance the acid resistance and chemical resistance, so as to increase the bonding force between components. The silicone resin is a polymer mainly composed of silicon and oxygen bonds, and enhances the bonding force to strengthen the binding force between the constituents. And triethanolamine is a weakly alkaline buffer added to control acidity. Petrolatum is an ointment-like material composed mainly of amorphous solid hydrocarbons and is waterproof and added to enhance the formation, and polycarbonate The resin is a base resin.

16, when the door 2300 is closed, the unit controller 4210 recognizes the closing of the door 2300 so that the unit controller 4210 can close and lock the locking plate 4220. [ A limit switch (LMT) can be further provided.

The limit switch LMT is electrically connected to the unit controller 4210 to transmit a detection signal. The unit controller 4210 receiving the detection signal drives the driving motor 4280 to close the locking plate 4220 The door 2300 is operated to automatically lock so as not to be opened.

At this time, when the limit switch LMT, to which the drive motor 4280 is locked, transmits a detection signal, the unit controller 4210 operates the solenoid-type locker LOC to rotate the drive gear 4270, And the solenoid-type locker LOC is operated in the reverse direction to release the lock state so that the drive gear 4270 is in a rotatable state.

To this end, the upper frame FRM is further provided with a solenoid type locker (LOC), which is electrically connected to the unit controller 4210 to be controlled.

Particularly, an insertion groove (GOV) is formed on one side of the driving gear 4270 so that the solenoid type locker (LOC) can be inserted and removed. At least one stopper (STP) is formed around the inner diameter of the insertion groove (GOV) So that the solenoid-type locker (LOC) can be caught and fixed when the solenoid-type locker (LOC) is inserted.

As described above, in the dual-purpose key unit 4200 according to the present invention, an authorized worker first opens the keyhole (HOL) with the key KEY to release the primary lock, and then transmits the ID card held by the authorized user to the ID card reader 4300 Lt; / RTI >

Then, the unit controller 4210 recognizes this and rotates the driving motor 4280 in a counterclockwise direction while lifting the locking plate 4220 in a counterclockwise direction, thereby creating an unlocking state in which the door 2300 can be opened.

Accordingly, the operator opens the door 2300 and enters the inside to perform a necessary operation.

When the door 2300 is closed after the completion of the operation, the unit controller 4210 closes the locking plate 4220 in the opposite direction of the above-described opening operation according to the detection signal of the limit switch LMT, Since the safety lock is performed even if it is not forgotten by the key, the child or the like can not open the door 2300, thereby preventing a safety accident.

In addition, as shown in FIG. 17, the drone 5000 used in the present invention is configured to photograph a photographing area while being held for at least four hours or more for a long time.

In the present invention, in order to increase the flying time of the drones 5000, the first and second storage batteries DC1 and DC2 are mounted in the battery box 5300. [

In this case, the first and second storage batteries DC1 and DC2 may be dual-redundant to switch two batteries, thereby increasing flight time.

A controller 14 is mounted between the first and second storage batteries DC1 and DC2 to switch the use of the first and second storage batteries DC1 and DC2. The DC power obtained from the DC power supply 5400 is supplied and charged.

In this case, the solar cell module 5400 is attached to the upper surface of the dron cover 5600, which seals the buoyancy groove 5500 formed on the upper surface of the dron body 5200.

Here, a voltage level detector (not shown) is further connected to the controller 14 in order to help increase the buoyancy because the air is filled in the buoyancy groove 5500 and to check the condition of the used battery among the two batteries. And the controller 14 uses any one of the first and second storage batteries DC1 and DC2 by sending a switching control signal related to the use of the battery according to the detection value of the voltage level detector, And accumulates the direct current electricity acquired from the battery module 5400.

The gas chamber 5700 is filled with helium gas on both sides of the buoyant groove 5500. The gas chamber 5700 is filled with a gas inlet 5720 And the gas injection port 5720 is sealed by an injection plug 5800. [
