Remote control system of mobile body {Remote control System of Mobile body}

The present invention relates to a remote mobile location control device, the mobile is the most comfortable and easy road by collecting and analyzing information using a kind of navigation device to guide the destination to the information such as the road condition, shopping location, driving speed, etc. You can choose to reduce the travel time. The latitude and longitude information was collected from the well-known Global Positioning System (GPS) satellites located above the Earth and collected the latitude and longitude information required for the location notation and matched with the latitude and longitude information of a predetermined electronic map to determine the current location. .

Such a device has a low GPS satellite signal in an urban area where buildings and underground buildings are densely populated, making it impossible to receive a real-time location, and it is not possible to perform real-time location marking. The use of orbital satellite adds a separate satellite fee, which incurs a burden.

Therefore, the present invention is attached to the electronic compass to collect the movement direction information of the moving object in the area where GPS satellite signal reception is impossible, and when the location tracking and emergency situation occurs using another wireless communication network operating on land for mobile control at a remote place The present invention relates to a remote mobile position control device for constructing a system that can be processed quickly.

 As shown in FIG. 1, in order to receive a good signal from several GPS satellites 1, a GPS antenna 101a of the mobile navigation apparatus 100 is constructed at the highest point of the mobile body 40 where there is no obstacle. The GPS module 102 for amplifying and analyzing the signal is disposed. In addition, a signal modulator / demodulator 109 for converting a signal into a suitable transmission form for transmission to the low-orbit communication satellite 2 and a low-orbit communication satellite antenna 101c for signal transmission and reception are provided. Travel speed measuring device 500 for detecting the moving speed of the mobile body 40 and transmitting it to the mobile navigation device 100, the latitude and longitude information received from the GPS satellite 1 and the moving speed of the traveling speed measuring device 500. The central processing unit 103 which collects and analyzes the information, and the electronic map display window 108 which informs the operator of the position of the moving object 40 by matching the analyzed latitude and longitude information with the latitude and longitude information of a predetermined electronic map. It is provided.

A fixed station remote control center 200 and a mobile station terminal 130 capable of receiving the mobile unit latitude and longitude information from the remote site and controlling the mobile unit 40 are configured.

 Under such a system, in the conventional mobile navigation apparatus 100, an area where normal signal reception is not possible in the "underground space of a building", "tunnel of a road", "inner city area where high-rise buildings are crowded", etc., where the GPS satellite 1 is not visible. Is a combination of the moving speed information of the traveling speed measuring device 500 attached to the moving object 40 and the latitude and longitude information received from the final GPS satellite 1, and matches the latitude and longitude information of a predetermined electronic map to display the electronic map display window. In 108, the position of the movable body 40 is indicated.

Under such a system, when the mobile body 40 is located in an area where GPS satellite 1 signals cannot be received, and the direction of the mobile body 40 is changed, the mobile navigation device 100 moves on the basis of the final GPS satellite 1 signal. Since 40 is predicted to move in the same direction and is indicated on the electronic map display window 108, even if the moving body 40 changes the moving direction, the moving body 40 continues to move in the same direction.

Database (DB) is stored in the server (210). By matching the stored latitude and longitude information with the latitude and longitude information of the electronic map previously designated by the server computer 210, the mobile station 40 remotely confirmed the position of the mobile body 40 and received the low-orbit communication satellite signal 2 exclusively. In the terminal 130, the location of the remote body 40 was checked in real time.

In such a method, since the frequency used by the low-orbit communication satellite 2 is very low, an antenna large enough to receive a signal is essential, and many problems arise in attaching and moving the antenna to the mobile body 40.

In order to receive the low-orbit communication satellite (2) signal from a remote mobile station, a separate reception-only mobile terminal 130 is inefficient.

     Still another object of the present invention is to send a signal to the remote section of the remote area by transmitting the latitude and longitude information of the mobile object using another wireless communication network operating on land for the purpose of identifying and controlling the movement path and position of the mobile object at a remote location. The signal is received from another wireless communication base station located and the signal is transmitted to the wired section of the internet network.

      The signal is transmitted to a fixed station remote control center at a remote location and a mobile station remote control device capable of confirming while moving the position of the moving object in real time.
