The present invention relates to a logistics monitoring system using a satellite positioning system, and more particularly, to a logistics monitoring system using a satellite positioning system that enables real-time monitoring of logistics movement in a customs free zone.

In general, logistics refers to the flow of products from producers to consumers, and includes both the process of transporting, unloading, storing and packing the produced goods, and the distribution of goods such as distribution processing and transport infrastructure. It takes more than one stage of distribution process before a product is produced and delivered to the consumer, and the manufacturer owns a vehicle for this distribution process or sends it to a specialized logistics company.

Conventionally, various types of online information sharing systems have been established and utilized between logistics companies (transporters) and companies (customer companies) for efficient logistics management. In recent years, systems operated online through networks and the Internet are widely used. It is used.

In other words, in the conventional manual system in which the driver reports the status in transit to a mobile phone, a system for periodically informing the location of transportation of vehicles and cargoes by connecting a GPS module and a mobile phone network, a wireless data network, or a satellite network. During this operation, however, the real-time location tracking of the vehicle was difficult, so there was a problem in that it was impossible to obtain various and accurate information and operate accordingly.

Logistics movement monitoring is a big part of establishing the logistics system. Logistics management is, in a broad sense, managing the movement of logistics from the immediate production to the consumer. Therefore, it is possible to infer the route and estimated time of arrival, select the optimal route and means of transportation, and manage them systematically only when the current location of moving logistics is made quickly and accurately. In addition, all logistics should be located within the customs free zone.

For example, facility managers, such as ports and airports, need to load, unload, and store cargo efficiently, and carriers or cargo owners should be able to prevent or cope with problems such as vehicle dispatch, loss of cargo, and delays in transportation. In addition, due to the large amount of logistics entering and leaving the airport and port, careful attention must be paid to management, and in the case of a free area of tariffs, the real-time movement of all logistics should be continuously monitored due to the nature of the region that is related to taxes when moving out. Therefore, it is very important to track the location of the logistics in real time, but the conventional general location management and tracking system has difficulty in acquiring the weather information, the observation time, the satellite information in the stationary state and the position information in the moving state in real time. There was a problem that cannot be monitored in real time.

The present invention was created to solve the above problems, and an object of the present invention is to provide a monitoring system of logistics using a satellite positioning system to monitor the movement of logistics entering and exiting the customs free area.

Logistics monitoring system using a satellite positioning system according to the present invention for realizing the above object, the satellite receiver installed in the transport vehicle transport, and a database for classifying and storing the location information received using the satellite receiver; A location information agent server comprising a communication module for transmitting stored location information in association with the database;

First, each server mentioned in the present invention is connected to the wired / wireless communication network 300 or the Internet using the same, which is a technology for the main office, and thus a separate description is omitted. In addition, although each server is not shown in the drawings, such as the general hardware, computer operating system (Operating System) and various application programs, such as the main processor, network adapter, display adapter, main memory, auxiliary storage and input and output devices, It includes software, and this is also a technique for the public administration in the technical field of the present invention, so the separate description will be omitted.

Logistics monitoring system using the satellite positioning system of the present invention is largely composed of a location information agent server 10 and the monitoring agent server 20.

The location information agent server 10 uses a configuration of a conventional satellite positioning system, and transmits and receives a GPS satellite group consisting of a plurality of GPS satellites 200 and these GPS satellite groups to and from the logistics transport vehicle 100 or And a satellite receiver 11 which is a GPS antenna mounted on a loaded container or the like.                     

Here, the GPS satellite group is generally composed of 24 satellites, including 3 spare satellites, and orbits the earth at 12 hour intervals with 6 orbits distributed at equal intervals at a slope of 55 ° with respect to the equator at an altitude of 20,000 km. do. In addition, the GPS satellite groups transmit the assigned code and message signals to the logistics transport vehicle 100, respectively.

As described above, the location information agent server 10 to which the conventional satellite positioning system is applied includes a satellite receiver 11 installed in the logistics transport vehicle 100 that is largely moving, and location information received by using the satellite receiver 11. And a communication module 13 for transmitting and storing the stored location information in association with the database 12.

Here, the location information measured from the satellite signal of the logistics transport vehicle 100 is stored in the form of MNEA (LLQ) message as the measured position data and additional data (satellite number, ambiguity determination, etc.) related at the time of location measurement and monitoring. The monitoring control room, that is, is transmitted to the monitoring agent server 20 is provided to the end user and visualized in the monitoring program using the transmitted data. At this time, the monitoring program is based on the MapObject program, and in the program, NMEA (LLQ) messages are classified for each information, the location data is calculated using the classified information, and the location data is used in the monitoring program. To visualize. While monitoring, the user can make more objective judgment by providing current time, speed, direction of progress, gradual position realization, current absolute coordinates, number of observation satellites and ambiguity.

On the other hand, the location information agent server 10 is a wireless modem for connecting to the mobile communication network 300, and a portable computer equipped with an application program is used, the logistics transport vehicle 100 is given a unique identification code It is preferable to be configured to prevent data confusion with the other logistics transport vehicle 100.

The location information agent server 10 configured as described above communicates with the GPS satellite group by using the satellite receiver 11, and the satellite signal at this time is stored in the database 12 and through the communication module 13. The acquired satellite signal, that is, location information is transmitted to the monitoring agent server 20 connected to the wired or wireless communication network.

The monitoring agent server 20 classifies and processes the reception module 21 for receiving the location information transmitted from the location information agent server 10 and the location information provided in connection with the reception module 21.
