Description

Security management system of aviation RFID container

The present invention relates to a security management system of an aviation unit load device (ULD) container, and more particularly, to prevent theft of cargo by opening and closing the door of the ULD container in an air logistics transportation process, The present invention relates to a security management system for an aviation ULD container that enables quick identification and response of security-related information even in the event of a lost accident.

In general, in the field of air logistics, cargo carried by land is miraculous to aircraft through a series of processes, while cargo carried by aircraft is unloaded to land logistics.

At this time, in the case of the existing process, there is no security device from loading the air cargo to the air pallet or the air ULD container until the cargo is miraculized in the actual aircraft. The service process of the air logistics is as follows.

Common air logistics and land logistics linkage services include: 1) aircraft arrival / departure, 2) cargo miracle / unloading, 3) break down, build up, 4) cargo classification, and 5) cargo takeover / takeover. 6) Logistics warehouse, 7) Ground transportation, 8) Export / receipt in order, and check handwritten documents for cargo in the classification, B / D, and Build Up process. Online registration / printing will take place.

That is, only the method of manually listing the cargo list of cargo at the time of loading the existing aviation ULD container by hand or registering it in the database is searched online. It is difficult.

In particular, it was a general process to proceed with unsecured and unconfirmed status when aviation ULD containers were shipped to the warehouse for cargo miracle / unloading.

As described above, even if the door of the aviation ULD container is opened illegally during the transportation of the air logistics that is carried out by the worker's manual or insecure state, it is difficult to recognize the cargo immediately, and the information about the illegal opening or theft of the container is difficult. Was post-checked with no status and only reimbursed for lost cargo.

In case of loss of cargo, it is difficult to take preventive measures in the future, in spite of the cost loss, because there is no responsibility for loss of cargo and no information about where it is lost. There is no way to check for.

This problem will eventually halve the reliability of the company's freight transportation, and can be a problem that lags behind the competition in logistics services with other companies.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to check the illegal opening and closing of the air ULD container in transit to prevent theft of cargo due to the illegal opening of the container, as well as the cargo To provide security management system of aviation ULD container that enables security management to be strengthened by grasping responsibility and prompt information about lost place in case of accident.

Here, the power control unit 124 monitors the state of charge of the battery 121 to generate a charge or replacement signal of the battery 121 and transmits to the control unit 160.

The environmental sensor unit 130 collects environmental information of cargoes carried in the aviation ULD container 10, and the memory unit 140 is a list of the cargo information and collected by the environmental sensor unit 130 It stores the environment information of the cargo including temperature, humidity, vibration, shock, acceleration, and the opening and closing detection information of the door. Here, the environmental sensor 130 is a sensor for collecting information such as temperature, humidity, vibration, shock, acceleration, geomagnetism, etc., may be composed of a combination of one or more heterogeneous sensors.

In addition, the environmental sensor unit 130 may monitor in a periodic or event manner through the sensor is installed the necessary environmental information according to the cargo characteristics carried in the aviation ULD container 10.

The warning notification unit 150 drives an alarm or a buzzer so that the freight manager can recognize unauthorized opening and closing of the door and theft of the cargo according to generation of the opening / closing detection information of the door 12. Wake-up only by a driving command of the RFID reader system 200 to perform driving control to enable wireless communication with the RFID reader system 200, and the power supply unit 120 and the environmental sensor unit ( 130 and control operations of the memory 140 and the alert notification unit 150 as a whole.

In addition, the semi-passive sensor tag 100 controls the driving of the door opening and closing sensor 110 in accordance with the security setting of the seal processing of the RFID reader system 200, the door 12 of the aviation ULD container 10 In the case of unauthorized opening and closing of the door 12 rather than the normal seal release, the opening and closing detection information sensed through the door opening and closing sensor 110 is stored and the alarm manager controls the cargo manager to recognize theft or unauthorized opening and closing of the door. do.

The RFID reader system 200 collects cargo information by recognizing the passive tag 11 attached to each cargo carried in the aviation ULD container 10 and registers online with the management server 300 through a network (not shown). It basically does it.

In addition, the RFID reader system 200 stores a list of the cargo information collected by the semi-passive sensor tag 100 attached to the aviation ULD container 10 and sets the security of seal processing.

At this time, the RFID reader system 200 and the passive operation mode for communicating in a passive mode with the passive tags 11 attached to each cargo carried in the airborne ULD container 10, and the airborne ULD container 10 Including a semi-passive operation mode for transmitting a driving command to the semi-passive sensor tag 100 attached to the semi-passive sensor tag 100 in communication with the semi-passive sensor tag 100 in a state of wake-up It is operated in the operation mode.

That is, since the RFID reader system 200 of the present invention can recognize both passive tags and semi-passive tags with one reader, efficiency is increased in terms of construction, operation, and maintenance of the system. Can be.

An operation process of the security management system of the aviation ULD container of the present invention having the above configuration will be described with reference to the accompanying drawings.

First, cargoes in which the passive tag 11 is attached to the internal space of the aviation ULD container 10 are loaded. In this case, before closing the door 12 of the airborne ULD container 10, the RFID reader system 200 collects cargo information through the passive tag 11 carried in the airborne ULD container 10 and wireless communication in the passive mode.

Next, the RFID reader system 200 performs online registration with the management server 300 connected to the collected cargo information by a network.

Next, the RFID reader system 200 wakes up by transmitting a driving command to the semi-passive sensor tag 100 attached to the aviation ULD container 10, and stores the list of collected cargo information in a memory unit ( 140 and secure the seal process.

As such, when the seal is secured, the aviation ULD container 10 is loaded on an aircraft and arrives at the destination, and when the door is opened and closed by someone before the seal is released by another RFID reader system, the aviation ULD container ( The door opening / closing sensor 110 corresponding to each other on the door 12 side and the container housing of 10) senses unauthorized opening and closing to store the opening / closing detection information in the memory 140, and the warning notification unit 150 By buzzing or alarming, the cargo manager can recognize the unauthorized opening and theft of the container door.

Accordingly, the freight manager can quickly identify whether and when the door 12 of the container is opened or closed at any place through analysis of the opening and closing detection information stored in the memory 140, and also the RFID reader system ( Through the wireless communication with the passive tags 11 using the 200, it is possible to quickly identify and cope with any cargo stolen.

Although the present invention has been described in more detail with reference to the embodiments, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.
