For this reason, it is necessary to turn off the power so that the terminal power supply that is the power supply of the cargo loading terminal 200 is not operated. In the arrival base airport, it is necessary to resume communication with the GPS in the cargo loading terminal 200 and transmit the current position information to the monitoring center 400 in order to realize cargo security in the security target section. For this reason, it is necessary to turn on the terminal power to operate the cargo loading terminal.

  FIG. 2 is a block diagram of an overall configuration of the terminal power supply control system 2000 according to the first embodiment. The terminal power supply control system 2000 mainly includes a cargo loading terminal 200, a wireless receiver 300, a monitoring device 405, and a wireless transmitter 500.

  The wireless transmitter 500 transmits predetermined various information by weak radio waves. Specifically, whether the terminal power supply is activated by receiving an input of a container ID, which is unique identification information of a container in which the cargo C is accommodated, from an airport clerk at the departure point of the section where the cargo is transported by the aircraft A Alternatively, a power control signal instructing whether or not to operate is transmitted. The wireless transmitter 500 mainly includes a display unit 510 and an operation unit 520. The operation unit 520 is a user interface such as a touch panel or a keyboard. The display unit 510 is a liquid crystal screen, for example, and displays a list of input contents to the user.

  The wireless receiver 300 is a means for receiving radio waves from the wireless transmitter 500 and includes a receiving unit 310 and a transmitting unit 320. The receiving unit 310 receives a transmitter ID, which is unique identification information for identifying the wireless transmitter 500, from the wireless transmitter 500 together with a power control signal. The transmitting unit 320 transmits the received power control signal and transmitter ID to the cargo loading terminal 200.

  The cargo loading terminal 200 is a terminal that is included in the cargo load in order to guard the cargo, periodically acquires current position information using GPS or the like, and transmits the current position information to the monitoring center 400.

  The power control unit 230 controls power OFF and ON for the terminal power (power SW 808) of the cargo loading terminal 200. Specifically, the power supply ON / OFF is controlled by switching the terminal power supply mode based on the power supply control signal received from the wireless receiver. Here, the power supply mode is a mode that determines whether or not the terminal power supply can be operated. There are two power modes: an operation mode (terminal power ON) and a non-operation mode (terminal power OFF) depending on the operation state of the cargo loading terminal 200.

  The operation mode refers to a state in which power is supplied to all internal circuits with respect to a terminal power source (power SW 808) that is a power source of the cargo loading terminal 200.

  The non-operation mode refers to a state in which power is supplied to only some internal circuits and no power is supplied to other internal circuits with respect to the terminal power supply (power SW 808) that is the power supply of the cargo loading terminal 200. In the first embodiment, a state in which power is not supplied to the second communication unit 250 and the position information acquisition unit 210 is referred to, and in this embodiment, this state is referred to as a power supply OFF.

  In addition, the power supply control unit 230 sets the power supply of the cargo loading terminal 200 in an inoperable state by illegally stealing the security target cargo during the period from the collection of the security target cargo before the security start or after the security start. In order to prevent the evasion, the power supply to the power SW 808 is not completely stopped even when an operation of pressing the power SW (terminal power) is received. Specifically, when the guard start signal has been received and the guard is in operation and the power mode is the operation mode, the power control is performed when an operation of pressing the power SW 808 (terminal power source) is received. The unit 230 does not completely stop power supply to the power supply SW808. On the other hand, when the power supply mode is inactive and the operation for pressing the power SW 808 is accepted, the power controller 230 does not completely stop the power supply to the power SW 808 when the power SW is in the non-operation mode The date and time when the pressing operation is received is recorded in a storage unit described later.

  The position information acquisition unit (positioning unit) 210 periodically acquires current position information by communication with a GPS (Global Positioning System) or the like when the power source is ON and the power mode is the operation mode. A positioning process for notifying the current position information of the cargo C is executed.

  The storage unit 220 is a storage medium such as a memory or a hard disk drive (HDD) that stores a power mode table.

Then, the terminal ID and transmitter ID authentication request is transmitted to the monitoring device 405 (step S912). When the power OFF signal, transmitter ID, container number, and terminal ID and transmitter ID authentication request are transmitted to the monitoring device 405, the speaker 295 outputs a buzzer sound indicating that communication is being performed to the monitoring center 400. (Step S914).

  Here, a transmitter ID authentication process in the monitoring apparatus 405 will be described. FIG. 10 is a flowchart of an authentication process procedure such as a transmitter ID in the monitoring apparatus according to the first embodiment. The communication unit 410 of the monitoring device 405 receives the power OFF signal, transmitter ID, container number, and terminal ID and transmitter ID authentication request from the second communication unit 250 of the cargo placement terminal 200 (step S1000).

  The authentication unit 420 refers to the transmitter management table and acquires the base and the operation state corresponding to the transmitter ID received in step S1000 (step S1002). The authentication unit 420 determines whether or not the transmitter ID is properly registered at the base (step S1004). When the authentication unit 420 determines that the transmitter ID is properly registered at the site (step S1004, Yes), the authentication unit 420 then proceeds to the site where the wireless transmitter 500 is installed. It is determined whether it is used correctly, that is, whether it is in a normal operating state (step S1006). When it is determined that the wireless transmitter 500 is in a normal operation state (step S1006, Yes), the authentication unit 420 sends a transmitter ID authentication enable signal for authenticating the transmitter ID to the second communication unit 250. Transmit (step S1008). On the other hand, if the authentication unit 420 determines in step S1004 that the transmitter ID is not properly registered at the base (step S1004, No), the authentication unit 420 does not authenticate the transmitter ID. Is transmitted to the second communication unit 250 (step S1012). Similarly, in step S1006, when authentication unit 420 determines that radio transmitter 500 is not in a normal operating state (step S1006, No), a transmitter ID authentication rejection signal indicating that transmitter ID is not authenticated is issued. It transmits to the 2nd communication part 250 (step S1012).

  The registration unit 430 registers the terminal ID, transmitter ID, container number, base, operation state, and operation date / time in the operation state management table (step S1010). As a result, when the portable reading terminal 100 receives a list display request of the cargo loading terminal 200 whose operation state is in the non-operation mode from the airport clerk at the departure point, a courier, or the like, the network is By referring to the operation state management table stored in the storage unit 440 of the monitoring device 405, the operation state stored in association with the container ID is the power supply OFF (non-operation mode). A list of the terminals 200 can be displayed.

  Returning to FIG. 9, the second communication unit 250 determines whether or not the transmitter ID authentication enable signal has been received from the communication unit 410 of the monitoring device 405 (step S916). When the second communication unit 250 determines that the transmitter ID authentication enable signal has been received from the communication unit 410 of the monitoring device (Yes in step S916), the registration processing unit 240 transmits the transmitter of the authenticated transmitter 500. The ID is registered in the power mode table (step S918). When the audio output unit (speaker) 295 receives the transmitter ID authentication enable signal, the audio output unit (speaker) 295 switches and outputs the buzzer sound being output (step S920). The power supply control unit 230 switches the current power supply registered in the power supply mode table to the power supply OFF (non-operation mode) (step S922).

  In addition, when the transmitter ID authentication enable signal is received from the communication unit 410 in step S916, the position information acquisition unit 210 cuts off communication with the GPS and stops the scheduled positioning (step S924). Then, the power control unit 230 turns off the power (step S926).

  When the second communication unit 250 determines in step S916 that the transmitter ID authentication enable signal is not received from the communication unit 410 of the monitoring device (step S916, No), the second communication unit 250 determines that the transmitter ID is not transmitted. It is determined whether or not an authentication rejection signal has been received a predetermined number of times (step S928). When the second communication unit 250 determines that the transmitter ID authentication rejection signal has been continuously received for a predetermined number of times (step S928, Yes), the second communication unit 250 operates abnormally due to theft or theft. It is determined that an operation from the wireless transmitter 500 in the state has been received, and an alarm is notified to the monitoring center 400 (step S930). On the other hand, when the second communication unit 250 determines that the transmitter ID authentication rejection signal has not been received a predetermined number of times (No in step S928), the process returns to step S912 (step S912).

  As described above, the cargo loading terminal 200 according to the first embodiment includes the power control signal (power OFF signal), the container number, and the transmitter ID for inactivating the terminal power supply via the wireless receiver 300. When receiving the transmitter ID authentication from the monitoring center 400 and receiving the transmitter ID authentication enable signal, the power source control unit 230 switches the power mode of the terminal power source to turn off the terminal power source (OFF) ). Accordingly, it is possible to turn off the power of the cargo loading terminal 200 without opening the cargo, to prevent a reduction in work efficiency, to improve security, and to realize cargo security.

  Next, the procedure of the switching process for switching the terminal power supply to ON by the cargo loading terminal 200 according to the first embodiment will be described. FIG. 11 is a flowchart of a switching process procedure for switching on the terminal power supply in the cargo loading terminal according to the first embodiment.

The wireless receiver 300 receives a power supply control signal (power ON signal), a container number, and a transmitter ID for turning the terminal power supply into an operating state from the wireless transmitter 500 via the receiving unit 310.

  First, the first communication unit 265 receives a power ON signal, a container number, and a transmitter ID from the wireless receiver 300 (step S1100).

  Next, the power supply control unit 230 switches the terminal power supply to ON (operation mode) and puts the power supply into an operation state (step S1102).

  Next, the power supply control unit 230 refers to the power supply mode table, and acquires a container number registered in the power supply mode table in advance (step S1104). The power supply control unit 230 determines whether or not the container number acquired in step S1104 matches the received container number (step S1106). If the power supply control unit 230 determines that the acquired container number matches the received container number (step S1106, Yes), the power supply mode table is referenced again to acquire the current power supply mode corresponding to the container number. (Step S1108). On the other hand, when the power supply control unit 230 determines in step S1106 that the acquired container number does not match the received container number (step S1106, No), a message instructing the user to operate again is displayed on the speaker 295. Is output by voice (step S1110).

  Next, the power supply control unit 230 determines whether or not the current power supply mode acquired in step S1108 is a non-operation state (that is, power supply OFF) (step S1112). If the power supply control unit 230 determines that the acquired current power supply is OFF (step S1112, Yes), the second communication unit 250 receives the power ON signal, transmitter ID, and container number received in step S1100. Then, the terminal ID and transmitter ID authentication request is transmitted to the monitoring device 405 (step S1114). When a power ON signal, transmitter ID, container number, terminal ID and transmitter ID authentication request are transmitted to the monitoring device 405, the speaker 295 outputs a buzzer sound indicating that communication is being performed to the monitoring center 400. (Step S1116).

  Here, a transmitter ID authentication process in the monitoring apparatus 405 will be described. FIG. 12 is a flowchart of an authentication process procedure such as a transmitter ID in the monitoring apparatus according to the first embodiment. The communication unit 410 of the monitoring device 405 receives the power ON signal, the transmitter ID, the container number, and the terminal ID and transmitter ID authentication request from the second communication unit 250 of the cargo placement terminal 200 (step S1200).

  The authentication unit 420 refers to the transmitter management table and acquires the base and the operation state corresponding to the transmitter ID received in step S1200 (step S1202). The authentication unit 420 determines whether or not the transmitter ID is properly registered at the base (step S1204). If the authentication unit 420 determines that the transmitter ID is properly registered at the site (step S1204, Yes), the authentication unit 420 then proceeds to the site where the wireless transmitter 500 is installed. It is determined whether it is used correctly, that is, whether it is in a normal operating state (step S1206). When it is determined that the transmitter 500 is in a normal operation state (step S1206, Yes), the authentication unit 420 transmits a transmitter ID authentication enable signal indicating that the transmitter ID is authenticated to the second communication unit 250. (Step S1208). On the other hand, when the authentication unit 420 determines in step S1204 that the wireless transmitter ID is not properly registered at the base (step S1204, No), the authentication unit 420 does not authenticate the transmitter ID. A transmitter ID authentication rejection signal indicating this is transmitted to the second communication unit 250. (Step S1212). Similarly, in step S1206, when authentication unit 420 determines that radio transmitter 500 is not in a normal operating state (step S1206, No), a transmitter ID authentication rejection signal indicating that transmitter ID is not authenticated is issued. It transmits to the 2nd communication part 250. (Step S1212).

  The registration unit 430 registers the terminal ID, transmitter ID, container number, base, operation state, and operation date / time in the operation state management table (step S1210). As a result, when the portable reading terminal 100 receives a list display request for the cargo loading terminal 200 whose operation state is OFF, such as an input of a container number from an airport clerk at the destination or a courier, etc., via the network. By referring to the operation state management table stored in the storage unit 440 of the monitoring device 405, the operation state stored in association with the container ID is the non-operation mode (OFF), that is, the power is off. It is possible to display a list of the cargo loading terminals 200.

  Returning to FIG. 11, the second communication unit 250 determines whether a transmitter ID authentication enable signal has been received from the communication unit 410 of the monitoring device 405 (step S <b> 1118). When the second communication unit 250 determines that the transmitter ID authentication enable signal has been received from the communication unit 410 of the monitoring device (Yes in step S1118), the registration processing unit 240 transmits the transmitter of the authenticated transmitter 500. The ID is registered in the power mode table (step S1120). When receiving the transmitter ID authentication enable signal, the audio output unit (speaker 295) switches and outputs the buzzer sound being output (step S1122). The power supply control unit 230 switches the current power supply mode registered in the power supply mode table to the operation mode (ON) (step S1124). Then, the power supply control unit 230 determines whether or not the unauthorized power-off time is stored in the storage unit 220 (step S1125a). When the power control unit 230 determines that the time of unauthorized power OFF is stored in the storage unit 220 (step S1125a; Yes), it is determined that an unauthorized power OFF operation has been performed during the non-operation mode. Then, an alarm indicating that the operation of turning off the unauthorized power supply is received and the date and time are transmitted to the monitoring center 400 (step S1125b), and the process proceeds to step S1126. When the power supply control unit 230 determines that the time of unauthorized power OFF is not stored in the storage unit 220 (step S1125a; No), the process proceeds to step S1126.

  When the transmitter ID authentication enable signal is received from the communication unit 410 in step S1118, the position information acquisition unit 210 starts communication with the GPS and resumes the timed positioning (step S1126).

  When the second communication unit 250 determines in step S1118 that the transmitter ID authentication enable signal is not received from the communication unit 410 of the monitoring device (No in step S1118), the second communication unit 250 determines that the transmitter ID is not transmitted. It is determined whether or not an authentication rejection signal has been received a predetermined number of times (step S1128). If the second communication unit 250 determines that the transmitter ID authentication rejection signal has been received a predetermined number of times (step S1128, Yes), the second communication unit 250 is in an abnormal operating state due to theft or theft. It is determined that an operation from the wireless transmitter 500 has been accepted, and an alarm is notified to the monitoring center 400 (step S1130). On the other hand, if the second communication unit 250 determines that the transmitter ID authentication rejection signal is not received more than a predetermined number of times (step S1128, No), the process returns to step S1114 (step S1114).

  As described above, the cargo loading terminal 200 according to the first embodiment receives the power supply control signal (power ON signal), the container number, and the transmitter ID to activate the terminal power supply via the wireless receiver 300. In addition, when the transmitter ID is requested to the monitoring center 400 and a transmitter ID authentication enable signal is received, the terminal power supply can be controlled by the power supply control unit to switch the terminal power supply ON / OFF state. . Accordingly, the cargo loading terminal 200 can be turned on without opening the cargo, and security can be improved and cargo security can be realized.

  Further, when the cargo loading terminal 200 according to the first embodiment is guarded and the power supply mode is the operation mode, when the operation for pressing the power SW 808 is received, the power of the power SW Without stopping supply, the monitoring center 400 is transmitted to the effect that an operation of depressing the power SW 808 has been accepted. Further, when an operation to press the power SW 808 is accepted when the power mode is the non-operation mode, the date and time when the operation to press the power SW 808 is received without stopping the power supply of the power SW When the power supply mode is switched to the operation mode after that, an operation of pressing the power supply SW 808 illegally and the date and time thereof are transmitted to the monitoring center 400. Therefore, even if the power SW 808 of the cargo loading terminal 200 is illegally pressed while the cargo to be guarded is being guarded, it is possible to prevent the cargo loading terminal 200 from becoming inoperable, and to continue to quickly make the abnormality. The effect is that it is possible to take detailed security measures.
