In addition, according to the invention described in claim 2 , the data detection terminal is connected to the GPS receiving unit and the mobile communication unit in the pre-departure handling area at the departure airport in response to the communication regulation using the telecommunication equipment. Although the power supply path is switched to a short circuit and the power supply is turned OFF, the power supply control for these communication system data processing units is independent of other non-communication system data processing units, so communication between the unloading stations at the arrival and departure airports Since the non-communication data processing unit can continue to operate while the power is on even in the restricted section, the status detection unit detects the transport status detected every time it detects the transport status including the anti-vibration status of air cargo. The abnormal occurrence log data detected during transportation in the communication restriction section can be used to determine whether the air cargo arrives at the arrival airport and is delivered at the unloading area after arrival.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows the overall configuration of an air freight transportation state monitoring system which is an example of the present invention. The air cargo transportation state monitoring system (hereinafter referred to as the present system) in the illustrated example is on the route L for transporting the air cargo D on the anti-vibration pallet P and arrives at the departure airport A before departure and arrival at the arrival airport. Information processing is performed so that the transportation state including the anti-vibration state of the air cargo D can be easily and accurately monitored even when the transportation using the telecommunication equipment is restricted between the after-loading site B. To do.

  Therefore, in this system, a data detection terminal R is attached to a vibration-proof pallet P that carries air cargo D and is transported, and the mobile communication network group 10 (domestic mobile communication network 10a and overseas roaming) is connected to the data detection terminal R. A network by connecting a transport management server S provided in the information center Z via a network group, and connecting a user terminal Q provided by a user W such as a shipping company or shipper via the Internet to the transport management server S. N and an external power supply control communication means C that performs short-range wireless communication with the data detection terminal R. In addition, a map content server T that provides map information is also connected to the network N.

  The pre-departure unloading area A at the departure airport is a container building (CFS: Container Freight Station) where the shipping company collects, stores, and stores the packed cargo (export cargo) before delivering it to the airline and loading it into the cargo compartment. is there. After arrival at the arrival airport, the unloading place B is a shed (CFS) for removing the packed cargo when the shipping company receives delivery of the packed cargo (imported cargo) from the airline. Since the transportation section between the unloading point A at the departure airport and the unloading point B after the arrival at the arrival airport has an adverse effect on aircraft instruments, etc., if communication is performed using telecommunications equipment, Communication using telecommunications equipment is regulated.

  As shown in FIG. 2, the anti-vibration pallet P includes a fixed lower base 11 which is a base assembled in a grid, an upper base 12 which is assembled in a grid on which an air cargo D is mounted, and a compression coil spring. The vibration isolation means 15 is provided, and the vibration isolation means 15 is erected as legs at the four corners between the lower base 11 and the upper base 12, and the upper base 12 and the lower base 11 are vertically connected by the vibration isolation means 15. The base 12 is elastically supported, and is assembled by being movably connected to the fixed undercarriage 11 in a three-dimensional direction. In the anti-vibration pallet P, data detection terminals R (R1 and R2) each composed of a data logger of the same electronic measuring instrument are attached to the lower platform 11 (primary side) and the upper platform 12 (secondary side).

  As shown in FIG. 3, the data detection terminal R includes a GPS receiver 19 that receives a GPS signal for performing GPS (Global Positioning System) positioning, and a mobile communication network. The mobile communication unit 20 that performs communication via the group 10, the state detection unit 25 that detects the transportation state of the air cargo D, the time management unit 30 that manages the current time information, and the functions of the terminal R are realized. The storage unit 35 for storing various data in addition to the program to be executed, the communication processing unit 39 for processing the data to be transmitted to the transportation management server S, and the power supplied from the main power supply E via the power supply circuit 49 are switched. A power supply switching unit 40, a display unit 44, and the like are provided, and these data processing units (components) are connected to a main control unit (CPU) 45 that performs operation control according to a program. In addition, the data detection terminal R of the present invention is characterized in that it has a short-range wireless communication unit 50 that performs short-range wireless communication with an external power control communication means C.

  The GPS receiver 19 receives the GPS wave (GPS information) from the GPS satellite G shown in FIG. 1 via the GPS antenna 21 according to the control of the main controller 45. The GPS information includes, for example, transmission time information from the GPS satellite G. The GPS receiver 19 calculates longitude / latitude information indicating the current location of the terminal R using the GPS information, and derives position information indicating the current location of the terminal R. The GPS receiver 19 outputs position information derived using GPS positioning to the storage unit 35 as position information a3. Note that the position information derived using GPS positioning includes not only the longitude / latitude information calculated from the GPS information but also data such as address information corresponding to the longitude / latitude information.

  As shown in FIGS. 1 and 3, the mobile communication unit 20 can communicate using international roaming using the mobile communication network 10 via the mobile communication antenna 22 under the control of the main control unit 45. It is like that. Therefore, the data detection terminal R can also be connected to the transportation management server S of the domestic information center Z using the international roaming service even when it is attached to the anti-vibration pallet P carrying the air cargo D and transported internationally. Can send and receive.

  The state detection unit 25 detects the transportation state of the air cargo in the transportation section from the departure point X to the landing point Y using a sensor according to the control of the main control unit 45 at a constant cycle (for example, every minute). Air freight transportation status refers to the acceleration of displacement caused by external forces such as vibration and impact that air cargo receives during transportation, the accuracy of cargo measured from the temperature, humidity, illuminance, etc. around air cargo that changes during transportation. It is the current state of quality. For this reason, the state detection unit 25 includes at least an acceleration sensor 25a in order to measure a vibration isolation state (impact / vibration buffering effect) of the vibration isolation pallet P, which is particularly important in the transportation state. In the illustrated example, in addition, a temperature sensor 25b and a humidity sensor 25c that are important for measuring the transportation state are provided. The sensor is not limited to these, and may include other detection sensors that measure physical phenomena such as illuminance, pressure, current, strain, and displacement.

  The acceleration sensor 25a measures the acceleration of the air cargo D and detects the vibration-proof state. Then, an electrical signal corresponding to the measured acceleration is output to the main control unit 45 and stored in the storage unit 35.

The time management unit 30 is, for example, RTC (Real
(Time Clock), the current time information is output to the communication processing unit 39 with the time being recorded by itself, while the GPS reception unit 19 manages the accurate time in light of the transmission time information received from the GPS satellite G.

  The storage unit 35 uses the time management unit 30 to manage the state data a1 indicating the air cargo acceleration detected by the state detection unit 25 using the sensor, that is, the transportation state including the vibration proof state, under the control of the main control unit 45. The state detection time a2 based on the current time information and the position information a3 of the terminal R at the time of state detection derived by the GPS receiver 19 using GPS positioning are associated with each other at regular intervals (for example, every 30 minutes B) Store as log data a.

  The communication processing unit 39 reads the log data a from the storage unit 35 at regular intervals (for example, every 60 minutes) in units of palettes, prepares for a list request from the user terminal Q, and manages transportation via the mobile communication unit 20. Send to server S.

  The power supply circuit 49 controls the power supplied from the main power supply E to each data processing unit. In particular, each of the GPS receiving unit 19 and the mobile communication unit 20 is independent of other non-communication data processing units. The power supply switching unit 40 that controls power supply is provided. Therefore, the power supply circuit 49 branches the power supply path from the main power source E into a communication system and the other two systems, and the power supply switching unit 40 and the GPS switch 41a provided in the power supply paths 41 and 42 of the communication system and the mobile communication By switching the switch 42a, power supply control is performed independently of other non-communication data processing units such as the state detection unit 25. The main power source E is constituted by a battery such as a dry battery. Therefore, the data detection terminal R can manage the log data “a” of the transport status in real time whenever and wherever it is in transit, even if it is difficult to use a commercial power supply for transporting with air cargo. The server S is likely to be sent.

  However, in the case of aircraft transportation, communication using telecommunications equipment is normally restricted in the transportation section between the unloading area A before departure at the departure airport and the unloading area B after arrival at the arrival airport. That is, it is a communication restriction section F in which communication cannot be performed using the data detection terminal R of the telecommunication device.

  Therefore, in the present invention, the data detection terminal R uses the power supply switching unit 40 to switch the power supply path between short and open of the power supply path to the GPS receiving unit 19 and the mobile communication unit 20 that perform communication among the data processing units. (Power ON / OFF control).

  Therefore, the power supply switching unit 40 performs short-range wireless communication via the short-range wireless communication unit 50, and according to the operation instruction data received from the preset power supply control communication means C, the GPS switch 41a and the mobile communication switch 42a is switched to control the short-circuiting and opening of the power feeding paths 41 and 42 that communicate with the GPS receiver 19 and the mobile communication unit 20.

  The short-range wireless communication unit 50 performs wireless communication with other short-range wireless communication units by a communication method compliant with a short-range wireless communication standard such as IrDA, RFID, IEEE802.15.x, ISO / IEC 18092, 14443, 21481. Transmitter / receiver to perform. As shown in FIGS. 1, 2, and 3, the short-range wireless communication unit 50 is formed separately from the data detection terminals R (R 1 and R 2), and is outside the rectangular outer frame portion 11 a of the gantry 11. It is attached to the side face m and electrically connected to the main control unit 45. However, the short-range wireless communication unit 50 may be built in the data detection terminal and electrically connected to the main control unit.

  On the other hand, the power control communication means C that operates externally is an electronic device having a short-range wireless communication unit 51 that can wirelessly communicate with the short-range wireless communication unit 50 of the data detection terminal R as shown in FIG. As long as the terminal R can be remotely controlled, it may be a remote controller, an IC card, or the like. Therefore, in the illustrated example, an IC card is used as the power control communication means C.

  The power supply control communication means C is configured by configuring the short-range wireless communication unit 50 of the data detection terminal R with an RFID reader, terminal authentication data (terminal ID number / password) for identifying the data terminal R to be controlled in advance, and power supply control Related operation instruction data (power on / off power on / off data, etc.) is related and set. The power control communication means C may use two IC cards for turning on the power to which power-on operation instruction data is written and for turning off the power to which the power-off operation instruction data is written.

  Therefore, in the present system, when there is a section to be transported by aircraft in the transportation route L, the air cargo D accompanied by the data detection terminal R to be controlled is loaded at the departure airport at the departure airport A and at the arrival airport after arrival. When it is brought into B, the power control communication means C is operated from the outside to operate the short-range wireless communication unit 50 without operating the data detection terminal R by directly touching and operating the data detection terminal R by unpacking the net and lashing packaging. When approached, the power supply switching unit 40 is controlled in accordance with the operation instruction data received from the power supply control communication means C by short-range wireless communication, and the short-circuit of the power supply paths 41 and 42 leading to the GPS receiving unit 19 and the mobile communication unit 20 (power OFF ) And open (power ON).

  Note that when the short-range wireless communication unit 51 is brought close to the short-range wireless communication unit 50 of the data detection terminal R, the power control communication means C sounds an operation confirmation sound “beep” and displays the result of the power on / off operation. A display unit (not shown) for LED display (red / green blinking) may be provided. On the other hand, the display unit 44 of the data detection terminal R also displays the power ON / OFF state of the GPS receiving unit 19 and the mobile communication unit 20 with LEDs (red / green blinking).

  On the other hand, as shown in FIG. 4, the transportation management server S includes a log data receiving unit 54 that receives the log data a transmitted from the communication processing unit 39 of the data detection terminal R, and a log received by the log data receiving unit 54. When the data storage unit 52 that stores the data a in palette units and the browsing request for the log data a from the user terminal Q, the data storage unit 52 is searched and the log data a corresponding to the browsing request is returned to the user terminal Q The search unit 55 is provided.

  On the other hand, as shown in FIG. 1, the user terminal Q is a personal computer, for example, but may be a data processing device such as a mobile phone or a PDA as long as data can be transmitted / received to / from the transport management server S via the Internet. .

  In the system having the above-described configuration, the air cargo D that the transportation company of the user W has received a transportation request from the shipper is loaded on the anti-vibration pallet P on the transportation route L for transportation before the departure of the departure airport. Air freight transported from origin X to destination Y via transport route L between the place A and the unloading place B after arrival at the arrival airport, including aircraft transportation where communication by telecommunications equipment is restricted Information processing for monitoring the transportation state of D will be described along the flowchart of FIG. 5 with reference to FIGS. 1 to 4 with a focus on control operations by the data detection terminal R, the transportation management server S, and the user terminal Q. .

  In the illustrated example, the air cargo D is collected at, for example, a shipping source, loaded on a vibration-proof pallet P and loaded onto a transport vehicle such as a truck, and then shipped to a shipping company's collection store (source X). Land transported to the departure airport, landed at the airport at the departure airport at the departure point A, delivered to the airline, transported by pallet dolly, etc., loaded into the cargo compartment, and then transported by aircraft, arrived at the arrival airport overseas. After arrival, when unloading is received at the unloading site B, it is unloaded, loaded into a transport vehicle such as a truck, etc., transported overseas to the local delivery store (overseas local transport), and sent from the local delivery store to the destination (landing) Y) Follow the transportation route L to be delivered to.

  Therefore, at the departure place X, the data detection terminal R having the corresponding terminal ID number is attached to the anti-vibration pallet P carrying the air cargo D to be collected, and the main power source E is turned on. Then, the data detection terminal R starts operation (S1), the state detection unit 25 measures the acceleration of the air cargo D using, for example, the acceleration sensor 25a at a constant period (for example, every minute), and the temperature sensor 25b. The temperature is measured using, and the transportation state of the air cargo D is detected. On the other hand, the state data a1 including the acceleration (anti-vibration state) and temperature indicating the transportation state of the air cargo D detected by the state detection unit 25 is the state detection time a2 based on the current time information managed by the time management unit 30. And the position information a3 of the terminal R at the time of detection of the state derived by the GPS receiver 19 using GPS positioning are stored and accumulated in the storage unit 35 as log data a at a constant cycle (for example, every minute). (S2).

  At the time of this data detection, as shown in FIG. 2, the anti-vibration pallet P has a data detection terminal R (R1) on a fixed lower base 11 (primary side) and a movable upper base 12 (secondary side). R2) is attached, and the acceleration sensor 25a of each state detection unit 25 measures not only the fixed position on the primary side but also the acceleration on the secondary movable position different from that, and the vibration isolation state ( By detecting the shock / vibration buffering effect) as the transport status of air cargo D, it is possible to more accurately grasp the anti-vibration status of the transport cargo during transport, and transport including the more accurate anti-vibration status. The status log data can be provided to the user W in an easy-to-understand manner.

  Then, the accumulated log data a is read by the communication processing unit 39 from the storage unit 35 in units of pallets at regular intervals (for example, every 60 minutes) and transmitted to the transport management server S via the mobile communication unit 20 ( S3). On the other hand, when the log data receiving unit 54 receives the log data a transmitted from the communication processing unit 39 of the data detection terminal R, the transportation management server S prepares the log data a for a browsing request from the user terminal Q. The pallet is identified in series and stored in the data storage unit 52 (S4).

  Therefore, in this system, the user W can browse the log data a regarding the transport status of the desired air cargo by accessing the transport management server SWEB site via the Internet N using the user terminal Q ( S5).

  Thus, for example, during the domestic land transportation, the browsing information processing executed when the transportation management server S receives a browsing request for the log data a related to the transportation state of the specific air cargo D during the domestic land transportation. With reference to FIGS. 7 and 8, the control operation of the user terminal Q will be mainly described along the flowchart of FIG.

  As described above, the transport management server S, when receiving the log data a from the data detection terminal R (S100), prepares for the browsing inquiry from the user W, and saves it in the data storage unit 52 in pallet units in time series. (S101) When a browsing request for specific log data a is received from the user terminal Q (S102), the data storage unit 52 is searched according to the browsing request content (S103), and the searched log data a is sent to the user terminal Q. Reply (S104).

  Then, the user terminal Q that has received the search log data displays the log data search image 59 and the log data list image 60 on the display unit in FIG. 7 (S105). Next, when the map display instruction button 60a in the list image 60 is pressed, the position of the data detection terminal R is superimposed on the map as shown in FIG. 8 (S106a). When one of the positions of the data detection terminal R displayed on the map is clicked, data corresponding to this plot is displayed on the map as shown in FIG. Further, by pressing the graph display instruction button 60b in the list image 60, a graph 60c based on the log data a is displayed as shown in FIG. 9 (S106b). Then, when the plot of the graph 60c based on the log data a is clicked, the position corresponding to this plot is displayed on the map as shown in FIG. 10 (S107).

  Therefore, according to this system, when receiving the log data a from the data detection terminal R, the transportation management server S prepares for a browsing inquiry from the user W, and saves it in the data storage unit 52 in pallet units in time series. When a browsing request for specific log data a is received from the terminal Q, the data storage unit 52 is searched according to the browsing request content, and the log data a corresponding to the browsing request is returned to the user terminal Q. For example, the user can easily check the transport status of the air cargo being transported at any time and accurately grasp it.

  Now, during transportation, as shown in FIG. 1, the air cargo D is communicating with the GPS receiving unit 19 and the mobile communication unit 20 of the data detection terminal R (R1, R2) attached to the anti-vibration pallet P. The state detection unit 25 detects the transportation state and continues to collect data. After arriving at the departure airport after domestic land transportation, it is loaded with lashing nets, etc. for aircraft transportation at the unloading site A before departure. However, in the case of air transportation, the section F between the unloading site A before departure and the unloading site B after arrival at the arrival airport uses the data detection terminal R of the telecommunication equipment. Communication is regulated.

  Therefore, this system operates the power supply switching unit 40 of the data detection terminal R by operating the power supply control communication means C externally, and supplies power to the GPS receiving unit 19 and the mobile communication unit 20 that perform communication among the data processing units. The paths 41 and 42 are short-circuited, and the power is turned off as shown in FIG. 5 (S6).

  Therefore, power control (power ON / OFF control) is performed by externally operating the power control communication means C to switch between short-circuiting and opening of the power supply paths 41 and 42 to the GPS receiver 19 and the mobile communication unit 20 of the data detection terminal R. The information processing to be performed will be described in detail according to the flowchart of FIG. 11 with reference to FIGS. 1 and 2, focusing on the control operation of the power control communication means C and the data detection terminal R.

  First, as described above, the power control communication means C includes terminal authentication data (terminal ID number / password) for identifying the data terminal R to be controlled in advance and operation instruction data relating to power supply control (power on / off power on / Off data, etc.) (S200), and when the air cargo D accompanied by the data detection terminal R to be controlled is brought into the pre-departure handling area A at the departure airport, power control is performed from the outside. When the communication unit C is brought close to the short-range wireless communication unit 50, the terminal authentication data and the power-off operation instruction data are transferred from the power control communication unit C to the main control unit 45 of the data detection terminal R through the short-range wireless communication. (S201).

  On the other hand, the data detection terminal R authenticates the power control communication means (IC card) C by the main control unit 45 based on the received terminal authentication data (S202). Therefore, the main control unit 45 does not operate when the terminal authentication data does not match (S203a), and when they match, the main control unit 45 reads the received setting information of the IC card C, and according to the operation instruction data of the setting information, the power supply switching unit 40 And the power supply paths 41 and 42 of the GPS receiver 19 and the mobile communication unit 20 are switched to a short circuit and the power is turned off (S203b). Then, the main control unit 45 reports the result of the power OFF operation to the display unit 44 and returns it to the power control communication means C of the IC card by short-range wireless communication (S204). Then, the data detection terminal R displays the power OFF state on the LED by the display unit 44 according to the result report of the power OFF operation (S205a). On the other hand, the power control communication means C sounds a power off operation confirmation sound “beep” and displays the result of the power off operation in an LED (S205b).

  In view of this, this system responds to communication regulations using telecommunication equipment at the departure point A at the departure airport, controls the power supply switching unit 40 according to the operation instruction data received from the power control communication means C, and controls the main power supply. The power supply paths 41 and 42 from E to the GPS receiving unit 19 and the mobile communication unit 20 are switched to a short circuit and the power supply is controlled to be turned OFF. The power supply control for these communication system data processing units is shown in FIGS. As shown, since it is independent of the other non-communication data processing unit, the data detection terminal R loads the air cargo D at the pre-departure handling area A and delivers it to the airline, then the pallet dolly etc. The non-communication data processing unit can continue to operate while being transported and loaded into the cargo compartment and transported by aircraft, and the state detection unit 25 continues to accelerate at a constant cycle (for example, every minute). Capacitors 25a measures the acceleration of the air cargo D is used to detect the transport state of the air cargo D by measuring the temperature using a temperature sensor 25b. On the other hand, the state data a1 including the acceleration (anti-vibration state) and temperature indicating the transportation state of the air cargo D detected by the state detection unit 25 is the state detection time a2 based on the current time information managed by the time management unit 30. Are stored and accumulated in the storage unit 35 as log data a at a constant cycle (for example, every minute) (S7).

  After that, when the air cargo D arrives at the overseas arrival airport via aircraft transportation and receives the delivery of the air cargo D from the airline at the unloading site B after the arrival, communication using the data detection terminal R of the telecommunication equipment Regulations are lifted.

  Therefore, in this system, the power supply control communication unit C is externally operated again to operate the power supply switching unit 40 of the data detection terminal R, and among the data processing units, the GPS reception unit 19 and the mobile communication unit 20 that perform communication are connected. The power supply paths 41 and 42 are switched to open, and the power is turned on as shown in FIG. 5 (S8).

  Therefore, the power supply control communication means C is externally operated to open the power supply paths 41 and 42 to the GPS receiving unit 19 and the mobile communication unit 20 of the data detection terminal R. The control operation of the communication means C and the data detection terminal R will be mainly described along FIG. 11 with reference to FIGS.

  First, when the air cargo D accompanied by the data detection terminal R is brought into the unloading area B after arrival at the arrival airport, if the power control communication means C is brought close to the near field communication unit 50 from the outside, the near field communication is performed. Thus, the terminal authentication data and the power ON operation instruction data are transferred from the power control communication means C to the data detection terminal R (S201). On the other hand, the data detection terminal R authenticates the power control communication means (IC card) C by the main control unit 45 based on the received terminal authentication data (S202), and does not operate when the terminal authentication data does not match (S203a). When they match, the setting information of the received IC card C is read, the power supply switching unit 40 is controlled according to the operation instruction data of the setting information, and the power supply paths 41 and 42 of the GPS receiving unit 19 and the mobile communication unit 20 are controlled. Switching to open and turning on the power (S203b).

  Therefore, as shown in FIG. 5, the data detection terminal R is in transit between the unloading point A at the departure airport and the unloading point B after the arrival at the arrival airport, that is, the GPS receiver 19 and the movement of the communication system. The state detection time a2 managed by the time management unit 30 is associated with the state data a1 indicating the transportation state of the air cargo D detected by the state detection unit 25 with the section F in which the body communication unit 20 is turned off, and the storage unit The log data a stored and accumulated in 35 is read from the storage unit 35 by the communication processing unit 39 in units of pallets, and transmitted to the transport management server S via the mobile communication unit 20 (S9). On the other hand, when the log data receiving unit 54 receives the log data a transmitted from the communication processing unit 39 of the data detection terminal R and accumulated during the transportation between the landing areas A and B at the arrival and departure airports, These stored log data a are also identified and stored in the data storage unit 52 in chronological order in preparation for a browsing request from the user terminal Q (S10).

  Then, after the air cargo D is unloaded at the unloading station B after arrival at the foreign arrival airport, it is loaded into a transport vehicle such as a truck, through a local delivery store to the destination (landing Y), FIG. 1 and FIG. As shown in FIG. 3, the land transportation (overseas field transportation) is performed outside the country, but the data detection terminal R operates even during the overseas land transportation, and the state detection unit 25 performs acceleration sensor 25a at a constant cycle (for example, every minute). Is used to measure the acceleration of the air cargo D, and the temperature is measured using the temperature sensor 25b to detect the transportation state of the air cargo D. On the other hand, the state data a1 including the acceleration (anti-vibration state) and temperature indicating the transportation state of the air cargo D detected by the state detection unit 25 includes the state detection time a2 managed by the time management unit 30 and the GPS reception unit 19. Is associated with the position information a3 of the terminal R at the time of state detection derived using GPS positioning, and is stored and accumulated in the storage unit 35 as log data a at a constant cycle (for example, every minute). The accumulated log data a is read by the communication processing unit 39 from the storage unit 35 in a constant cycle (for example, every 60 minutes) in units of pallets and transmitted to the transport management server S via the mobile communication unit 20 (S11). .

  On the other hand, when the log data receiving unit 54 receives the log data a transmitted from the communication processing unit 39 of the data detection terminal R, the transportation management server S prepares for a browsing request from the user terminal Q, and pallets in time series. And are stored in the data storage unit 52 (S12).

  After that, when the air cargo D requested to be transported to the shipper is delivered to the delivery destination (landing Y) and the delivery is completed, the main power source E is disconnected and the operation of the data detection terminals R (R1 and R2) is stopped. Thus, the information processing of this system for monitoring the transportation state of the air cargo D is completed.

  Therefore, according to the above-described system, as shown in FIGS. 1 and 3, the pre-departure unloading area A and the arrival point arrive at the transportation route L on which the air cargo D is mounted on the anti-vibration pallet P and transported. The data detection terminal R responds to the communication regulation using the telecommunications equipment in the departure area of the departure airport in response to the communications regulation using the telecommunications equipment between the unloading place B after arrival at the airport including the transportation using the telecommunications equipment. At the front unloading site A, the power supply switching unit 40 is controlled according to the operation instruction data received from the external power control communication means C, and the power supply paths 41 and 42 to the GPS receiver 19 and the mobile communication unit 20 are switched to a short circuit. The power supply control for these communication data processing units is independent of other non-communication data processing units, so the communication restriction section F between the unloading airports A and B at the arrival and departure airports. Non-communication data processing Since the unit can continue the operation with the power ON, the state detection unit 25 can detect the transportation state including the vibration-proof state of the air cargo D as it is, while the transportation state detected during transportation in the communication restriction section F can be detected. When the air cargo D arrives at the arrival airport and receives the delivery at the unloading station B and the communication regulation is released, the log data a is received by the GPS receiver 19 according to the operation instruction from the external power control communication means C. By switching the power supply path to the mobile communication unit 20 to open and turning on the power, the data detection terminal R stores the log data accumulated during aircraft transportation to the transport management server S via the mobile communication unit 20. It can transmit and can prepare for the browsing request from user terminals Q, such as a shipping company and a shipper. In this way, according to this system, even if air freight is transporting the communication restriction section F between the landing areas at the arrival and departure airports, it is possible to detect and collect data on the transportation status, and users such as shipping companies and shippers can communicate Once the regulations are lifted, the transportation status in the communication regulation section F can be viewed and confirmed at any time, which makes it possible to visualize the transportation condition in the communication regulation section, and as a result, Even without relying on listening from crew members or the like, it is possible to easily and accurately grasp the transportation state including the vibration-proofing state of the air cargo in real time.

  By the way, in the illustrated example, in the data detection terminal R, the state detection unit 25 detects the transportation state such as the vibration proof state of the air cargo D using the acceleration sensor 25a or the like at a constant cycle. Each time the air freight transport status is detected at regular intervals, it is determined whether the detected transport status exceeds a predetermined standard, and if it exceeds the standard, abnormal transport It can also be configured to determine the state and transmit it to the transportation management server S as abnormality log data.

  Therefore, in this system of this other example, the data detection terminal R preliminarily sets a reference transport condition threshold value (acceleration threshold value, temperature threshold value, humidity threshold value, etc.) and stores it in the storage unit 35 shown in FIG. On the other hand, each time the state detection unit 25 detects a transportation state including an air cargo anti-vibration state at a certain period, the data detection terminal R reads a reference transportation state threshold value from the storage unit 35 and detects the detected transportation state. The main control unit 45 is provided with an abnormal state determination unit 65 that determines whether or not the state is an abnormal state exceeding a predetermined transport state threshold, and the transport state detected by the abnormal state determination unit 65 is determined in advance. When it is determined that the abnormal state exceeds the threshold value of the state, the state data indicating the abnormal state and the time of detection of the abnormal state are associated with each other and stored in the storage unit 35 as the abnormality occurrence log data. A configuration is used in which the data is transmitted to the transport management server S via the mobile communication unit 20.

  On the other hand, when the transportation management server S receives the state data indicating that the detected transportation state indicates an abnormal state and the abnormality occurrence log data that associates the time of detection of the abnormal state, the transportation state of the air cargo D is in an abnormal state. An electronic document containing the above information is transmitted to an e-mail address registered in advance, and a specific user W is notified that an abnormality has occurred in the air cargo D.

  Therefore, this system of another example is used in the transportation route L in which the air cargo D is mounted on the anti-vibration pallet P and transported, before the departure at the departure airport A and at the arrival airport B at the arrival airport. The data detection terminal R responds to the communication regulation using the telecommunication equipment, and the power control communication means C in the unloading place A before departure at the departure airport when the communication includes the aircraft transportation regulated by the telecommunication equipment. The power supply switching unit 40 is controlled in accordance with the operation instruction data received from the power supply line 41 and 42 from the main power source E to the GPS receiving unit 19 and the mobile communication unit 20, and the power supply is controlled to be turned off. Since the power supply control for the communication system data processing unit is independent of other non-communication data processing units, the communication restriction section F between the unloading airports A and B is also a non-communication data processing unit. Works with the power on Therefore, the state detection unit 25 detects the transportation state including the vibration-proofing state of the air cargo D as it is, and whenever the transportation state is detected, the abnormal state determination unit 65 reads the storage state from the storage unit 35. Reads the threshold value of the transport condition as a reference, determines whether the detected transport condition is an abnormal condition that exceeds the threshold value of the transport condition, and determines that the detected transport condition is an abnormal condition that exceeds the threshold value of the transport condition. Then, the state data indicating the abnormal state is associated with the time of detection of the abnormal state, and is stored and stored in the storage unit 35 as abnormality occurrence log data in preparation for notification of the occurrence of the abnormality to the registered user W.

  Then, in this system, when the air cargo D arrives at the arrival airport, and after receiving the delivery of the air cargo D at the unloading site B, the communication restriction is released, the data detection terminal R detects in the communication restriction section F When the abnormality log data is read out from the storage unit 35 and transmitted to the transportation management server S via the mobile communication unit 20 by the communication processing unit 39, the transportation management server S An electronic document containing information indicating that the transportation state of the air freight D detected during transportation in the communication regulation section F is abnormal is sent to the registered e-mail address and sent to a specific user W Notify that an abnormality has occurred in Air Cargo D.

  In the above illustrated embodiment, an example is shown in which a data logger is used as the data detection terminal R. However, in the present invention, the data detection terminal is not limited to the data logger, and is an electronic device such as a data recorder or an IC tag. It may be a measuring instrument.
