In FIG. 1, the starting point 110, the stop point 120, and the end point 130 are named to clearly describe the operation of the present invention, and mean each logistic base, in particular, when the track is installed next to the highway. A logistics base should be constructed at the site adjacent to the rest area to reduce installation costs.

In describing an embodiment of the present invention, a case in which the cargo is shipped from the starting place 110 and transported to the stopping place 120 and the destination 130 will be described as an example.

First, for the shipment of cargo, the cargo classification apparatus 112 classifies each cargo by shipping address and attaches the type and shipping information of the cargo to the corresponding cargo by using a barcode or RFID.

After that, when the wagon 200 is stopped at the loading station 310, the cargo transported through the conveyor is shipped to the wagon 200, which may be automatically loaded by a person or by installing a separate loading equipment. .

By the way, the wagon 200 is automatically moved to the loading station in communication with the central control unit 111, when arriving at the loading station to communicate with the vehicle detector 320 installed in the corresponding loading station to stop at the loading position of the cargo The control unit 210 stops the wagon 200 at the correct shipping position by controlling the driver 230 in communication with the vehicle detector 320, and after the wagon 200 stops, the door opens. The driving unit 260 is controlled.

In addition, the control unit 210 prevents illegal loading or unloading of the cargo by controlling the door opening only when communication with the vehicle detector 320 installed at the loading or unloading station or by a specific operation of the manager.

Then, when the shipment of the cargo is completed, the control unit 210 controls the door driving unit 260 to close the door, and communicates with the central control unit 111 through the communication unit 250 to start the operation.

In this case, when the wagon 200 starts to travel to the destination and leaves the starting point 110, the vehicle detecting unit 113 confirms the departure of the wagon 200 and informs the central control unit 111.

Subsequently, the controller 210 determines the current driving position through the position determining unit 280 and notifies the central control unit 111 via the communication unit 250 while the wagon 200 is traveling to the destination. The 111 detects where the respective wagons are currently operating and controls the wagons. At this time, the position determining unit 280 may be configured to determine the current position by detecting the current position through the sensors installed on the track at predetermined intervals or by measuring the driving speed to calculate the driving distance or by using the GPS to determine the current position. Can be.

In addition, while the wagon 200 is in operation, the control unit 210 performs an operation of detecting an object in front of the object through the object detecting unit 270. If the preceding wagon is approached within a predetermined distance and confirmed as an object detection, the control unit ( The 210 controls the driving unit 230 to adjust the traveling speed to prevent a collision with the vehicle in front.

Then, when the wagon 200 approaches a predetermined distance from the stopover 120, the track switching unit 122 communicates with the communication unit 250 to collect delivery address information from the control unit 210, and the delivery point information is the stopover 120. If it is determined to be) to change the track of the branch point 125 so that the wagon 200 is driven into the stopover 120.

At this time, when the vehicle detecting unit 123 detects that the wagon 120 is traveling in the stopover 120 and notifies the line transfer unit 122, the line transfer unit 122 transfers the line again to the destination 130. It is possible to prevent the traveling wagon from running to the stopover 120 and to operate the wagon to the destination 130. By the way, since a plurality of wagons are operated on the track, the wagons other than the wagons that operate in the stopover 120 may wait for the track to be switched again if necessary by reducing the running speed when the track is switched. The control unit 210 may determine through communication with the line switching unit 122 through the communication unit 250.

Accordingly, the wagon 200 guided to travel in the stopover 120 is moved to the loading dock through communication with the independent control unit 121. The loading dock may be installed in the same manner as in FIG. 3, and the wagon 200 stops at a loading position by communicating with a vehicle / cargo detector 320 installed at the loading dock, and opens a door for loading and unloading cargo.

Therefore, the cargo loaded on the wagon 200 is unloaded and transferred to the cargo sorting apparatus 124 through a conveyor. The vehicle / cargo detector 320 communicates with the control unit 210 of the wagon 200 and is installed at a position capable of recognizing a barcode or RFID attached to the cargo at the time of loading or unloading the cargo. It may be configured to detect the unloading, the communication between the vehicle / cargo detector 320 and the control unit 210 may be applied to the Zigbee, wireless LAN, Bluetooth.

Accordingly, the freight classification device 124 determines the shipping address information through a barcode or RFID attached to each cargo and classifies the shipping address.

In addition, the independent control unit 121 transmits the information according to the arrival of the wagon 200, the unloading and the delivery of the cargo shipped to the wagon 200 to the central control unit 111 through wired and wireless communication.

If the wagon 200 approaching the stopover 120 and the line changer 122 communicate with each other to determine the wagon driven to the destination 130, the line changer 122 does not perform the line change. Accordingly, the wagon 200 continues to travel to the destination 130.

Thereafter, when the wagon 200 is driven into the destination 130, the vehicle detecting unit 133 detects the entry of the wagon 200 and informs the independent controller 131.

At this time, the wagon 200 is in communication with the independent control unit 131 to run to the loading dock, and arrives at the loading dock in the same way as the operation at the stop 120 (120).

Accordingly, when the cargo shipped to the wagon 200 is unloaded, the logistics classification apparatus 132 classifies each cargo by delivery address.

On the other hand, the wagon 200 is described as an example only when the delivery destination 120 or the destination 130, but when the wagon 200 is to be operated to one of a plurality of destinations at a branch point, a plurality of tracks are switched It should be configured to

In addition, in the above-described starting point 110, but only the operation of loading and unloading the cargo at the stopper 120 and the destination 130, but in practice the starter 110, the destination 120, the destination 130 In the loading and unloading of the cargo are all performed, the loading and unloading of the cargo is made in the same process as the operation described above.

In addition, in order to transport the cargo from the stopover 120 or the destination 130 to the starting point 110, a separate track will be more convenient. That is, when only one track is installed for freight transportation, the traffic is generated and the efficiency of freight transportation will be reduced. Based on the starting point 110, an uphill track and a downward track are installed for freight transportation. Can be configured to prevent traffic.

In addition, the power supply unit 220 provided in the wagon 200 is provided with a current collector to receive power from the power line installed in the line, but it is provided with a component such as a battery, ADC, so as to charge the battery By configuring, it can be configured to operate by using the power charged in the battery in an emergency.

On the other hand, the central control unit 111 is located in the starting place 110 to control the overall operation of the system as well as to control the loading and unloading of cargo at the starting place 110, the starting place Independent control unit 110 is separately installed in the central control unit 111 may be configured to control the operation of the overall system by communicating with the independent control unit and the line transfer unit installed on the track in each distribution base.

In addition, the wagon 200 has been described on the assumption that the cargo mounting unit 240 is integrally coupled to the wagon, it can be manufactured to be detachable to the cargo mounting unit 240, such as a container box. In this case, the freight truck 200 may improve the inefficiency of loading or unloading the cargo only in a state where it is stopped at the loading dock or the loading dock.

That is, in the case of loading the cargo, the cargo is loaded in advance on the cargo mounting unit 240 separated from the wagon 200, and then mounted on the wagon 200, and when the cargo is unloaded, arriving at the wagon 200 at the destination. When the cargo mounting unit 240 is separated from the wagon 200 to perform a cargo unloading operation, the wagon 200 may improve the disadvantage of waiting for a long time at the loading dock.

As described above, a case in which the cargo mounting unit 240 is detachably manufactured like the container box has been described as an example. As shown in FIG. 4, a vehicle that can mount the container box at the rear of the wagon 200 ( It can also be configured by mounting a coupling that can connect the trailer). Therefore, if the above configuration can be applied to a plurality of trailers can be connected to the wagon 200, it is possible to transfer a lot of cargo to the destination at a time.

Although the embodiments of the present invention have been described in detail above, it will be understood that the present invention can be embodied in various forms without departing from the spirit and essential characteristics of the present invention by those skilled in the art. Could be.
