Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Referring to FIGS. 1 to 5, the GPS geodetic survey system (hereinafter referred to as "geodetic survey system") with improved precision according to the present invention 1000 is a GPS satellite 1100, a vehicle 1200, and a sign unmanned vehicle. It includes a broadcasting unit 1300, a vehicle operation unit 1400, a communication network 1500, and a road construction central server 1600.

The GPS satellite (1100) consists of 24 constant altitudes of 20 to 25 km (Km) above ground, preferably about 20.183 km on average, and at least 3 GPS satellites received from the GPS satellite (1100). When analyzing a signal, it is a global positioning system (GPS) that broadcasts a GPS signal that can be analyzed at sea level, longitude, latitude and time for free, and is generally known.

The vehicle 1200 is a general transportation method that can move on the road 900 together with people and various devices, equipment, and cargo.

The signage unmanned broadcasting unit 1300 is installed at a reference point location around the road 900 and receives GPS signals broadcast by the GPS satellite 1100 and uses ultrasound and laser from a vehicle 1200 passing through the reference point. While tracking the moving vehicle by using the result of the arithmetic mean calculation processing of the measured moving speed value, the traffic condition information around the road 900 is broadcast as a directional signal to the vehicle 1200.

The signless unmanned broadcasting unit 1300 includes a first GPS receiving unit 1310, a ground control unit 1320, a wireless communication unit 1330, a loop sensor unit 1340, a speed measuring unit 1350, a memory unit 1360, and an ISM broadcasting unit. (1370), a rotating motor unit 1380, a configuration that includes a rotating antenna unit 1390.

The first GPS receiver 1310 receives a GPS (GPS) signal broadcast by the GPS satellite 1100, analyzes it and outputs it as first coordinate information including latitude, longitude, elevation, and time.

Here, the vehicle 1200 is described as having a vehicle operation unit 1400 mounted thereon.

The ground control unit 1320 connects to the first GPS reception unit 1310, inputs first coordinate information, controls and monitors the loop sensor unit 1340 installed at the reference point, detects the point of time when the vehicle 1200 passes the reference point, and measures speed. By controlling and monitoring the unit 1350, the moving speed of the vehicle 1200 detected in two ways is arithmetically averaged to increase the reliability of the detected moving speed value.

On the other hand, if the ground control unit 1320 is confirmed that the vehicle 1200 has passed through the loop sensor unit 1340 installed at the reference point, it is input and managed from the external or road construction central server 1600 through the communication network 1500, The traffic control information of the surrounding area corresponding to the first coordinate information of the area where the signage unmanned broadcasting unit 1300 is installed is controlled to be wirelessly broadcast as a frequency signal in the ISM band through a directional antenna composed of the Hoengantenabu 1390 At the same time, it monitors each function and outputs the respective control signals.

The ISM (Industrial Scientific Medical band) band is a radio frequency band in which a frequency of the 2.4 GHz or 5.7 GHz band is used and a user can use it free of charge without obtaining a separate license from the government.

High-speed data communication of 11 Mbps to 54 Mbps can be performed using the ISM band.

In order to minimize interference between users, the ISM (ISM) band has a maximum output and a spreading factor, and frequencies in the 900 MHz, 2.4 GHz, and 5.7 GHz bands are allocated worldwide, and recently Bluetooth (Bleetooth) Can also be used in

The wireless communication unit 1330 accesses the central server 1600 of the road construction via the communication network 1500 under the control of the ground control unit 1320, transmits the first coordinate information of the ground control unit 1320, and the central road construction server ( 1600) receives the traffic situation information provided by selecting and providing content corresponding to the first coordinate information of the ground control unit 1320 and transmits the received traffic condition information to the ground control unit 1320.

The roof sensor unit 1340 is the same length as the width of the road 900, and preferably has a width of 30 to 60 centimeters (cm).

The loop sensor unit 1340 is installed at a randomly designated reference point on the road 900 on which the vehicle 1200 runs and constitutes a loop of a conductor that is well-connected to electricity, and functions as a coil of an electric circuit.

That is, the signal that the loop sensor unit 1340 detects the passage of the vehicle 1200 is applied to the ground control unit 1320, and the ground control unit 1320 controls the speed measurement unit 1350 to pass the vehicle through the reference point ( 1200) is detected.

The speed measuring unit 1350 measures the moving speed of the vehicle passing through the reference point where the loop sensor unit 1340 is installed by the corresponding control signal of the ground control unit 1320. The speed measuring unit 1350 is used to measure the ultrasonic unit 1351 and the laser unit 1352. Including.

By analyzing, it is possible to measure the moving speed of the vehicle 1200.

In addition, since the transmission and reception of the ultrasonic signals are repeated at a certain time difference, and the time at which each ultrasonic wave is transmitted and the received time are analyzed, the moving speed of the vehicle 1200 may be measured.

Ultrasound is a sound wave over the frequency band of about 20,000 hertz (Hz) that cannot be heard by humans, and it has the advantage of being easy to handle and moving at a distance of about 340 meters per second (m), but because the transmission speed is slow, the detectable distance is short and the surroundings Temperature can be affected.

The laser unit 1352 transmits a laser to a vehicle 1200 that has passed a reference point by a corresponding control signal of the ground control unit 1320, receives a laser that is reflected back from the vehicle 1200, and receives the returning laser signal. The Doppler effect of the received laser signal By analyzing, it is possible to measure the moving speed of the vehicle 1200.

In addition, since the transmission and reception of the laser signals are repeated at a constant time difference, and the time at which each laser is transmitted and the received time are analyzed, the moving speed of the vehicle 1200 may be measured.

The laser has a very high transmission speed, like light, and travels about 300 million meters per second, but it is relatively difficult to handle and has many problems affected by ambient humidity, snow, rain, and fog. There may be very poor accuracy.

Therefore, the speed measuring unit 1350 is equipped with an ultrasonic unit 1351 using ultrasonic waves and a laser unit 1352 using lasers at the same time, and each of the measured values is processed by the ground control unit 1320 for arithmetic average calculation, so that the vehicle 1200 It can increase the reliability of the moving speed measurement.

The ground control unit 1320 may measure the arithmetic average as described above and perform arithmetic mean calculation to control the rotation of the antenna unit 1390 within a range of about 270 degrees in a state corresponding to the moving speed of the vehicle 1200 detected with high reliability.

The memory unit 1360 records and stores traffic situation information provided by the road construction central server 1600 by the corresponding control signal of the ground control unit 1320 and received through the wireless communication unit 1330 in the allocated area.

At this time, the ground control unit 1320 analyzes the coordinate information of the traffic situation information received from the central server 1600 of the road construction once again in detail and traffic conditions corresponding to the first coordinate information input from the first GPS receiver 1310. Filtering information may be recorded in an allocated area of the memory unit 1360.

The ISM broadcasting unit 1370 modulates and amplifies the traffic situation information corresponding to the first coordinate information of the unsigned broadcasting unit 1300 to the frequency of the ISM band according to the control signal of the ground control unit 1320, and amplifies the traffic condition information. It is output to the antenna section 1390 during the rotation.
