Meanwhile, in the case of the breaker 210 and the warning lamp 220 provided in the access control means, the operation is controlled through an 8-bit control board 450 additionally provided in the access control means 400. In addition, the data storage module 420 stores electronic invoice information, vehicle ID information, and image information capturing the front surface of the trailer. On the other hand, the information stored in the data storage module 420 as described above is transmitted to the logistics management server 500, so that users who access the logistics management server 500 can grasp the entry and exit information and the current status of the material in real time. . In addition, the display module 430 displays the stored electronic invoice information, vehicle ID information and image information to the operator, and also has a touch screen function for receiving a predetermined message from the operator. The control module 440 outputs a control signal related to the access control, and manages display information of the display module 430.

Hereinafter, with reference to the above-described configuration and Figure 5, the access control method according to an embodiment of the present invention will be described. 5 is a flowchart illustrating an access control method according to an embodiment of the present invention.

First, as the trailer approaches the entrance gate, the Zigbee module 100 receives the electronic invoice information sent from the trailer, transmits the received information to the access control means 400 via the RS-232C protocol, The RFID reader 120 reads tag information of a trailer near 3 to 10 m, identifies a vehicle unique ID stored in the tag information, and transfers the identified information to the access control means 400 through an RS-232C protocol. Transmit (S110-S120).

Thereafter, the access control means 400 stores the electronic invoice information and the vehicle unique ID, and notifies the logistics management server 500 of the access of the trailer through the switching hub 140 and the access point (AP) 130 ( S130-S140). At this time, the logistics management server 500 sends a short message to the field manager in conjunction with the SMS server (not shown), thereby inducing the field manager to move to the location.

At the same time, the access control means 400 requests the image acquisition means 300 to capture the front of the trailer, and receives the captured image information (S150-S160).

Then, the access control means 400 transmits the electronic invoice information and the vehicle unique ID and the captured image information stored in the logistics management server 500 to store the information (S170).

Then, the access control means 400 requests and receives material access and transportation plan information previously stored in the logistics management server 500 through the switching hub 140 and the access point (AP) 130, and receives the received information. Compare with the stored information to check whether the match (S180-S200).

At this time, if the material information is inconsistent, the access control means 400 transmits a control signal to the access control means 200, to prevent entry of the trailer (S210). That is, the control signal is transmitted to the breaker 210 and the beacon 220 to prevent the entry of the trailer and generate an alarm, and also send a message such as 'material information mismatch' to the signboard 230 to control the access situation. Inform.

Then, the access control means 400 transmits the same message to the trailer through the Zigbee module 110, thereby notifying the driver of the inaccessible situation (S220).

At the same time, the access control means 400 transmits the access control facts and causes to the logistics management server 500, and stores the corresponding information (S230). At this time, the site manager arriving at the site visually checks whether the trailer is free of material damage or defects, and if there is a problem, the display manager 430 provided on the access control means 400, for example, 'prohibit entry of material defect'. By touching the item, the message is displayed on the electronic display board 230 to inform the access control reason. On the other hand, if it is impossible to enter the trailer due to incorrect information or material defects, it is preferable to guide the site manager to handle the situation according to the procedure.

On the other hand, if the material information in step 'S200' or the entry permission item according to the visual confirmation of the site manager is touched, the control signal to the access control means 200 is transmitted to permit the entry of the trailer (S240). That is, the control signal is transmitted to the breaker 210 to permit the entry of the trailer, and transmit and display a message such as 'entry permission' and the moving destination information on the display board 230.

At the same time, the access control means 200 transmits the same message to the trailer through the Zigbee module 110, thereby notifying the driver of the entry permission and the moving destination (S250). At the same time, the access control means 400 transmits the access control situation to the logistics management server 500 to store the corresponding information (S260).

As can be seen from above, the access control system according to the present invention automatically recognizes in real time the vehicle and the materials loaded on the vehicle construction site, by managing the information integrated to improve the efficiency in the logistics management process In addition, cost loss can be prevented by thoroughly monitoring the loss and damage of materials.

Although the present invention has been described in detail with reference to the preferred embodiments, the present invention is not limited to the above-described embodiments, and the present invention belongs to the present invention without departing from the gist of the present invention as claimed in the following claims. Anyone skilled in the art will have the technical idea of the present invention to the extent that various modifications or changes are possible.
